TECHNICAL FIELD
[001] This currently disclosed subject concerns headrests, and more particularly headrests for use in conjunction with a seat. HISTORY OF THE INVENTION
[002] Headrests are used to provide improved head and neck support to a user while sitting in a seat, for example, in case the user falls asleep or in the case of an individual with physical disorders. A headrest can be used to prevent the user's head from falling forward or tilting to the left or right side. This provides comfortable and stable support of the user's head while sitting in the seat.
[003] For example, during sleep, the muscles in the neck and back of the human body that normally support the head are relaxed. The result of this, when human beings (such as babies) are asleep in a car seat, their head will fall forward or “roll” to the right or left, putting pressure on the user's neck or spine and causing discomfort that diminishes quality. of sleep that the child enjoys. While driving on city streets, the forces associated with the vehicle's acceleration, braking, and sharp corners, respectively, further magnify the harmful effects on the neck and spine caused by the child's head not being supported.
[004] There are many headrests for adults and children that are known in the art. An example is disclosed in US 7,740,318, which discloses a padded strap that is attached to both sides of an infant vehicular seat using two sets of ring and handle type fasteners, and alternatively, through the use of two rotating discs. The additional example is disclosed in US 2013/0300176, which discloses a headrest system that includes a support arm formed of a flexible material, which is displaceable between a first position that extends horizontally over a forehead portion of a child and a second position arranged away from the child's forehead. SUMMARY OF CURRENTLY DISCLOSED TOPIC
[005] According to a first aspect of the subject currently revealed, a headrest is provided which comprises:
[006] a headrest member configured with a back and two side parts extending therefrom;
[007] a mounting arrangement hinged to the headrest member for mounting the headrest to a seat; and
[008] a limiting member fundamentally articulated to said lateral parts and configured to rotate at least between an ascending position and a descending position.
[009] The headrest is configured to provide improved head and neck support to a user while sitting in a seat, for example, in case the user falls asleep or in the case of an individual with physical disorders. More particularly, the restraining member is configured to prevent the user's head from falling forward, and the headrest member is configured to prevent the user's head from tipping to the left or right side. This provides comfortable and stable support for the user's head while sitting in the seat. The headrest can be mounted on any seat, such as a vehicle seat, in order to provide heightened head and neck stability to a user during vehicle cornering, braking or collision.
[0010] In use, when the user's head is positioned on the headrest, the limiting member, in its ascending position, may be located substantially above the user's head and, in its descending position, the limiting member may be located substantially in front of the user's forehead.
[0011] The term 'user' as used herein in the specification and claims means an individual, an infant, a child or an adult.
[0012] The term 'vehicle' as used herein in the specification and claims indicates a wheelchair, an automobile, a bus, a train, a vessel, an aircraft, and the like.
[0013] The term 'seat', as used herein in the specification and claims, refers to a booster seat, an infant vehicle seat, a safety seat, a baby carriage, a vehicle seat, a wheelchair seat , a chair, a bench, etc. The term 'seat' also refers to a part of a seat, such as a seat headrest, or any other part of any conventional seat.
[0014] The headrest can be a complement, that is, it can be installed in different types of seats.
[0015] Any one or more of features, designs and configurations may be incorporated into the subject currently disclosed, according to the first aspect, independently or in combination thereof:
[0016] The sides of the headrest member may be foldable relative to the rear, so as to allow the headrest member to assume a first state in which the sides are spaced apart in a first measure and a second state in which the sides are spaced apart by a second measure which is smaller than said first measure.
[0017] In the second state, the sides can be arranged close to the user's ears. This can be useful to reduce noise and therefore improve the user's sleep quality.
[0018] Each of the sides can be configured with an earphone, so that in the second state the earphones are arranged close to the user's ears to provide sound to them. The sound can be, for example, relaxing music, a story or a parent's voice.
[0019] The displacement of the restraining member between its ascending position and its descending position can be configured to cause the headrest member to assume its first and second states, respectively.
[0020] The back and sides can be integral and continuous or attachable to each other.
[0021] The back and sides can be formed as support pads.
[0022] The back is configured to support the back of the user's head, and the sides are configured to support the sides of the user's head. The sides can form a side impact protector for the user's head.
[0023] The rotation of the limiting member between the ascending and descending positions can be performed by the user himself using one of his hands.
[0024] In the descending position, the limiting member can be spaced from the user's forehead so that a gap extends between the forehead and the limiting member. This gap can provide an extra measure of comfort to the user, as there is no contact between the forehead and the limiting member. However, the gap should not be too large in order to allow the limiting member to operate effectively to delimit forward head movement.
[0025] The restraining member can be configured with two side members and a center member disposed between them. One of the side members can be hinged fundamentally to an outer face of a side part of the headrest member, and another of the side members can be hinged fundamentally to an outer face of another side part of the headrest member. The central connection can be provided by pressure fasteners.
[0026] The central member of the restraining member can be formed as a strip.
[0027] Each of the side parts can be configured with a boundary channel formed on its outer face.
[0028] Each of the side members can be configured with a projection part configured to be received in its respective delimitation channel and moved between the two extreme ends of these by moving the limiting member between the ascending and descending positions.
[0029] The side members and the boundary channels can be made of a flexible yet rigid plastic material. For example, the side members and fencing channels can be made of a polymer such as polypropylene.
[0030] The boundary channels may have an arc shape, the length of which corresponds to the angle between the headrest member and the limiting member in their ascending and descending positions.
[0031] The headrest can be modular and can have the following two configurations:
[0032] - a front configuration in which the limiting member is fundamentally mounted on the headrest member to be moved between its ascending and descending positions; and
[0033] - a rear configuration in which the restraining member is arranged on the rear side of the headrest member and connected thereto; in the rear configuration, the restraining member substantially completely engages an outer face of the headrest member; in the rear configuration, the headrest can be compactly packed by being rolled up or folded.
[0034] The restraining member can have a variable length in order to: adjust the distance between the user's forehead and the restraining member, adjust the distance between the top of the user's head and the restraining member, and adjust the headrest to different head sizes.
[0035] The side members can be articulated to the central member by ring and loop type fasteners (eg Velcro® fasteners).
[0036] The ring and handle type fasteners can allow the adjustment of the length of the limiting member. In addition, ring and loop type fasteners can allow adjustment of the vertical location of the center member in relation to the side members. This vertical adjustment allows the placement of the central limb exactly in front of the user's forehead (for example, a child). However, when an adult uses the headrest member, the center member may be located in front of their eyes so that it can be used as a sleep mask.
[0037] The central member can be flexible and can be formed of a soft and rigid material, although malleable.
[0038] The headrest member can also be flexible and can be formed of a soft and rigid, yet malleable material.
[0039] The mounting arrangement may comprise two pairs of straps. Each pair of straps is articulated to each other through connection means such as buckles, length adjustment elements or strap-and-ring type fasteners.
[0040] The mounting arrangement can be configured to secure the headrest to a headrest of the seat seat.
[0041] The mounting arrangement can be used to adjust the height of the headrest in relation to the seat and the height of the user's head.
[0042] The headrest may further include a detection unit mounted to it to detect situations in which a child or infant is left alone in the vehicle. Such a detection unit can be configured with an alert system to alert these situations.
[0043] The headrest may further include a microphone mounted on it to amplify the user's voice (for example, a child's voice).
[0044] According to a second aspect of the matter currently disclosed, a headrest is provided which comprises:
[0045] a headrest member configured with a rear part and two side parts extending therefrom; and
[0046] a limiting member fundamentally articulated to said lateral parts and configured to rotate at least between an upward position and a downward position;
[0047] wherein the sides of the headrest member are foldable relative to the rear, so as to allow the headrest member to assume a first state in which the sides are spaced apart in a first measure and a second state in which the sides are spaced apart by a second measure, which is smaller than said first measure.
[0048] According to a third aspect of the matter currently disclosed, a seat is provided which comprises: (a) an accommodation portion; (b) a headrest seat; and (c) a headrest comprising a headrest member configured with a rear portion attached to the headrest seat and two side portions extending therefrom; and a limiting member pivotally hinged to said lateral parts and configured to pivot at least between an upward position and a downward position;
[0049] wherein the sides of the headrest member are foldable relative to the rear, so as to allow the headrest member to assume a first state in which the sides are spaced apart in a first measure and a second state in which the sides are spaced apart by a second measure, which is smaller than said first measure.
[0050] Any one or more of the following features, designs and configurations may be incorporated into the currently disclosed subject matter, in accordance with the second or third aspect, independently or in combination thereof:
[0051] Displacement of the restraining member between its ascending position and its descending position can be configured to cause the headrest member to assume its first and second states, respectively.
[0052] The back can be attached to the headrest seat through various means of attachment, such as: sewing, staples, a zipper, ring and strap type fasteners, etc.
[0053] The headrest can be attached to various types of seats, such as a booster seat, a safety seat, a baby carriage, a vehicle seat, a wheelchair seat, a chair, a bench, etc. .
[0054] In the second state, the sides can be arranged close to the user's ears. This can be useful to reduce noise and therefore improve the user's sleep quality.
[0055] Each of the sides can be configured with an earphone, so that in the second state the earphones are placed close to the user's ears to provide sound to them. The sound can be, for example, relaxing music, a story or a parent's voice.
[0056] The back and the sides can be integral and continuous or fixable to each other.
[0057] The back and sides can be formed as support pads.
[0058] The back is configured to support the back of the user's head, and the sides are configured to support the sides of the user's head. The sides can form a side impact protector for the user's head.
[0059] The rotation of the limiting member between the ascending and descending positions can be performed by the user himself using one of his hands.
[0060] In the descending position, the limiting member can be spaced from the user's forehead so that a gap extends between the forehead and the limiting member. This gap can provide an extra measure of comfort for the user, as there is no contact between the forehead and the limiting member. However, the gap should not be too large in order to allow the limiting member to operate effectively to delimit forward head movement.
[0061] The restraining member can be configured with two side members and a central member arranged between them. One of the side members can be hinged fundamentally to an outer face of a side part of the headrest member, and another of the side members can be hinged fundamentally to an outer face of other side parts of the headrest member. The central connection can be provided by pressure clamps.
[0062] The center member of the restraining member can be formed as a strap.
[0063] Each of the side parts can be configured with a boundary channel formed on its outer face.
[0064] Each of the side members can be configured with a projection part configured to be received in its respective boundary channel and moved between the extreme ends of these by moving the limiting member between the ascending and descending positions.
[0065] The side members and the boundary channels can be made of flexible yet rigid plastic material. For example, the side members and fencing channels can be made of a polymer such as polypropylene.
[0066] The boundary channels can have an arc shape, the length of which corresponds to the angle between the headrest member and the limiting member in their ascending and descending positions.
[0067] The headrest can be disconnected from the headrest seat.
[0068] The headrest can be modular and can have the following two configurations:
[0069] - a front configuration in which the restraining member is fundamentally mounted on the headrest member to be moved between its ascending and descending positions; and
[0070] - a rear configuration in which the restraining member is arranged on the rear side of the headrest member and connected thereto; in the rear configuration, the restraining member substantially completely engages an outer face of the headrest member; in the rear configuration, the headrest can be compactly packed by being rolled up or folded.
[0071] The limiting member can have a variable length in order to: adjust the distance between the user's forehead and the limiting member, adjust the distance between the top of the user's head and the limiting member, and adjust the support of head to different head sizes.
[0072] The side members can be articulated to the central member by ring and loop type fasteners (eg Velcro® fasteners).
[0073] The ring and handle type fasteners can allow the adjustment of the length of the limiting member. In addition, ring and loop type fasteners can allow adjustment of the vertical location of the center member in relation to the side members. This vertical adjustment allows the placement of the central limb exactly in front of the user's forehead (for example, a child). However, when an adult wears the headrest member, the center member may be located in front of their eyes so that it can be used as a sleeping mask.
[0074] The central member may be flexible and be formed of a soft and rigid material, although malleable.
[0075] The headrest member can also be flexible and be formed of a soft and rigid, yet malleable material.
[0076] The headrest may further include a detection unit mounted on it to detect situations in which a child or infant is left alone in the vehicle. Such a detection unit can be configured with an alert system to alert these situations.
[0077] The headrest may further include a microphone mounted on it to amplify the user's voice (for example, a child's voice). BRIEF DESCRIPTION OF THE DRAWINGS

[00108] Attention is first directed to Figs. 1A to 1F of drawings illustrating a headrest, in accordance with an example of the subject currently disclosed, generally designated 1.
[00109] The headrest 1 comprises a headrest member 10, a limiting member 40 pivotally hinged thereto and a mounting arrangement 70 extending from the headrest member 10 for mounting the headrest 1 as a complement to a safety seat 3 in which a child can be accommodated (shown in Figs. 1E, 1F, 2E and 2F), or to any other seat.
[00110] The restraining member 40 is configured to be rotated relative to the headrest member 10 about an X axis (shown in Figs. 1B and 2B) between an upward position (shown in Figs. 1A to 1F) and a position descending (shown in Figs. 2A to 2F). This rotation can be performed by the user, using one of their hands.
Reference is now made to Figs. 1F and 2F in order to explain the general mode of operation of the headrest 1, which is attached to a headrest seat 4 of a safety seat 3.
[00112] As shown in Fig. 1F, in the upward position of the restraining member 40, a child 5 is accommodated on the safety seat 3, its head 6 rests on the headrest member 10 and the restraining member 40 is arranged above the head 6 and arch-like in shape, however, with a sufficient gap over the child's head. Furthermore, the headrest member 10 is in its first state, in which its first and second side parts 20 and 30 are spaced apart in a first measure. In this position, the child 5 is awake and his head 6 is free to move in the forward direction and each side, limited, however, to a certain extent by the sides 4a and 4b of the seat headrest.
[00113] As shown in Fig. 2F, the child 5 has fallen asleep and thus the headrest 1 is in the downward position. In this position, the restraining member 40 is arranged in front of the forehead 7 of the child 5 in order to restrict the movement of the head 6 in the forward direction. Furthermore, the headrest member 10 is in its second state, in which its lateral parts are spaced apart by a second measure, which is smaller than the first measure, thus restricting the movement of the head 6 to the sides. . This restriction by the restraining member 40 and the sides of the headrest member 10 provides elevated stability and comfortable support of the head 6 while the child 5 sleeps. In particular, the restraining member 40 prevents the user's head 6 from falling forward, and the first and second side parts 20 and 30 prevent the user's head 6 from tipping to the left or right side. In addition, the above restriction can provide heightened head and neck stability to a user upon cornering, braking or vehicle collision.
Reference is now made to Figs. 1A to 1F in order to explain in detail the structure and operation of the headrest 1 with the restraining member 40 in its ascending position and the headrest member 10 in its first state.
[00115] The headrest member 10 has a back 12, a first side 20 and a second side 30. The back 12 and the first and second side parts 20 and 30 are formed as support pads for the child's head 6. As shown in Fig. 1B, the back 12 supports a back 9 of the head 6.
[00116] The first side part 20 and the second side part 30 extend from the two opposite ends of the back part 12, i.e. a first end 13 and a second end 14, respectively. Furthermore, the first side part 20 and the second side part 30 are foldable relative to the central part 12 between the first state (Figs. 1A to 1F) and the second state of the headrest member 10 (Figs. 2A to 2F ).
[00117] The restraining member 40 is configured with a first side member 50, a second side member 60 and a center member 42 disposed therebetween. The center member 42 is formed like a strap and, as shown in Fig. 1F, is arranged above the child's head 6.
[00118] The first side member 50 and the second side member 60 are secured to the center member 42 by ring and loop type fasteners. The ring and loop type fasteners allow the adjustment of the length of the restraining member 40, in order to adjust the distance between the child's forehead and the restraining member 40 (in the descending position of the restraining member), the distance between the upper part of the head of the child and the restraining member 40 (in the ascending position of the restraining member) and adjusting the headrest 1 to different head sizes.
[00119] In addition, the ring and handle type fasteners allow the adjustment of the vertical location of the central member 42 in relation to the first and second side members 50 and 60. For example, if the user of the headrest 1 wants to use the center member 42 as a sleep mask, he can position the center member 42 relative to the first and second side members 50 and 60 so that the center member 42 is located in front of his eyes, instead of his forehead.
[00120] The central hinge of the restraining member 40 to the headrest member 10 is provided by articulating the first side member 50 to an outer face 22 (shown in Fig. 3) of the first side part 20 by means of a first fastener by pressing 54 (shown in Fig. 3), and by pivoting the second side member 60 to an outer face 32 of the second side portion 30 by means of a second pressure fastener 64.
[00121] The first side part 20 is configured with a first boundary channel 52 (shown in Fig. 3) formed on the outer face 22, and the second side part 30 is configured with a second boundary channel 62 formed on the outer face 32 The first boundary channel 52 is formed within a channel element 51, which is mounted on the outer face 22. The second boundary channel 62 is formed within a channel element 61, which is mounted on the outer face 32. according to the particular example, the channel elements 51 and 61 of the outer faces 22 and 32 are related to a single element by being connected by a connecting strip (observed in Fig. 3).
[00122] The first boundary channel 52 and the second boundary channel 62 have an arcuate shape, the length of which corresponds to the angle between the headrest member 10 and the boundary member 40 between their ascending and descending positions. According to the present example, this angle is approximately 120°.
[00123] As can be seen in Fig. 3, the first side member 50 is configured with a first protruding part 55, which is received and slidably displaceable within the first delimitation channel 52 between the two extreme ends thereof by displacement of the limiting member 40 between its ascending and descending positions.
[00124] As shown in Figs. 1A and 1C, the second side member 60 is configured with a second projecting portion 65 (not shown in Fig. 1A), which is received and slidably displaceable within the second enclosure channel 62 between a lower end 66 and an upper end. 67 by moving the restraining member 40 between the ascending and descending positions, respectively. The lower end 66 further restricts the upward rotation of the restraining member 40 beyond its upward position, and the upper end 66 further restricts the downward rotation of the pressure member 40 beyond its downward position, thus preventing, for example, the central member. 42 is located below a predetermined level, for example, in front of the child's eyes.
[00125] The central member 42 is formed of a flexible and soft material. This material is rigid yet malleable. The headrest member 10 is formed from soft, flexible padding material. The first side member 50, the second side member 60, the two channel elements 51 and 61 are all made of a hard and rigid, yet malleable, plastic material. According to the present example, this material is polymer and, in particular, polypropylene.
[00126] It should be noted that, according to other examples, the headrest member 10 is not necessarily flexible, but in any case, it should allow the rotation of its sides.
[00127] The mounting arrangement 70 comprises a first pair of straps 72 and a second pair of straps 76. Each pair of straps is hinged to each of the other loop and loop type fasteners. According to the other examples, the strips are articulated to each of the other known mechanical means.
[00128] As indicated above, the headrest member 10 is shown in Figs. 1A to 1F in its first state. In this state, the first side part 20 and the second side part 30 are spaced apart by a first measure, represented by a distance D1 (Figs. 1B and 1D). Distance D1 is taken along an axis that is parallel to the axis of rotation X and traverses a center point 6' of the head 6. The first state of the headrest member 10 is in its normal state, to which the parts sides of the headrest member 10 tend to reverse. The normal state is provided due to the geometry and structure of the headrest member 10.
[00129] The restraining member 40 is structured so that the distance between the first and second side members 50 and 60 is substantially constant during the rotation of the restraining member 40 between its ascending and descending positions. In view of this feature of the restraining member 40, and the fact that the distance between the first and second side members 50 and 60 is less than the distance between the outer faces 22 and 32 in the upward configuration of the restraining member 40, the displacement of the restraining member 40 from its ascending position to its descending position causes the headrest member 10 to assume its second state. This result is provided by the first and second side members 50 and 60, which flex the first and second side parts 20 and 30 with respect to the back 12, respectively, causing them to come closer together. Likewise, the displacement of the restraining member 40 from its descending position to its ascending position causes the headrest member 10 to assume its first normal state.
[00130] Reference is now made to Figs. 2A to 2F in order to explain in detail the structure and operation of the headrest 1 with the restraining member 40 in its downward position and the headrest member 10 in its second state.
[00131] As shown in Fig. 2B, in the downward position of the restraining member 40, its central member 42 is located in front of the forehead 7 of the child's head 6, and spaced therefrom such that a gap m extends between center member 42 and forehead 7. Gap m provides an extra measure of comfort for child 5, since when child 5 is awake there is no contact between forehead 7 and limiting member 40. However, the gap should not be too large in order to allow the restraining member 40 to operate effectively when contact is made between forehead 7 and central member 42. This contact can be established if the child's head 6 falls in the forward direction. when she falls asleep.
[00132] Furthermore, as shown in Figs. 2B, the first and second side parts 20 and 30 support the sides 8 and 8' of the child's head (in Fig. 2B). The first and second side parts 20 and 30 further constitute a side impact protector for the user's head 6.
[00133] As indicated above, the headrest member 10 is shown in Figs. 2A to 2F in its second state. In this state, the first side part 20 and the second side part 30 are spaced apart by a second measure represented by a distance D2 (shown in Figs. 2B and 2D), which is less than the distance D1. Distance D2 is taken along an axis that is parallel to the axis of rotation X and traverses the center point 6' of the head 6. As shown in Fig. 2B, the first and second side parts 20 and 30 are arranged close to the the user's temples, thus reducing the noise that comes close to the child's ears and improving the quality of their sleep.
[00134] Distance D2 can be regulated by changing the length of the limiting limb 40. For example, if the child feels discomfort with the first and second sides touching their ears, the length of the limiting limb 40 can be increased, increasing thus distance D2.
[00135] The headrest of the subject currently revealed is modular and has two configurations: a front configuration (shown in Figs. 1A to 1F and 2A to 2F) and a rear configuration (shown in Fig. 4A).
[00136] As opposed to the front configuration, in which the restraining member 40 is pivotable between its ascending and descending positions, in the rear configuration, the restraining member 40 is not displaceable between these positions.
[00137] Reference is now made to Fig. 3, in which the headrest 1 is shown in its disassembled configuration. In this configuration, the headrest member 10 is disengaged from the restraining member 40. Furthermore, the restraining member 40 itself is disassembled so that the central member 42 is disconnected from its side member 50 and the second side member 60.
Reference is now made to Fig. 4A in order to describe the rear configuration of the headrest 1 in detail. In the rear configuration, the first and second side members 50 and 60 are hinged to a rear side of the headrest member 10 and connected thereto. In particular, the restraining member 40 fully engages an outer face 18 of the headrest member 10, the first side member 50 is hinged to the outer face 22 by means of a first snap fastener 54 (not seen in Fig. 4A). and the second side member 60 is hinged to the outer face 32 by means of the second snap fastener 64. The first and second projecting portions are withdrawn from their respective first and second boundary channels. As shown in Fig. 4A, in order to fully engage the restraining member 40 with the outer face 18 of the headrest member 10, the length of the restraining member 40 is reduced, respectively.
[00139] In the rear configuration, the headrest 1 is ineffective and can be transported from one location to another to be mounted on different seats when necessary. Furthermore, in the rear configuration, the headrest 1 can be packed compactly by being rolled up and folded in the direction of arrow 90.
[00140] Reference is now made to Fig. 4B, in which the headrest 1 is shown in its packaged form. This shape is obtained by rolling the headrest 1 of Fig. 4A in the direction of arrow 90. As seen in Fig. 4B, in packaged form, the headrest 1 is very compact and can be gripped by an adult's hand.
[00141] Attention is now directed to Figs. 5 and 6A to 6F of drawings illustrating a safety seat 103 with a headrest 100 in accordance with another example of the subject currently disclosed.
[00142] The safety seat 103 is configured with an accommodation part 101 configured to support a child's body and a seat headrest 104 configured to support a child's head. The headrest 100 is secured and integrated with the seat headrest 104 by means of stitching, and possibly forms a part of the safety seat 103.
[00143] Referring to Figs. 6A to 6F, the headrest 100 comprises a headrest member 110 and a restraining member 140 hinged fundamentally thereto. Constraining member 140 is configured to be rotated relative to headrest member 110 about an X axis (shown in Figs. 6B and 7B) between an up position (shown in Figs. 6A to 6F) and a down position (shown in Figs. 6B and 7B). in Figs. 7A to 7F). This rotation can be performed by the user, using one of their hands.
Reference is now made to Figs. 6F and 7F in order to explain the general operation of the headrest 100.
[00145] As shown in Fig. 6F, in the upward position of the restraining member 140, a child 105 is accommodated in the safety seat 103, its head 106 rests on the headrest member 110 and the restraining member 140 is arranged above the head 106 similar to a bow, however, with a sufficient gap over the child's head. Furthermore, the headrest member 110 is in its first state, in which its first and second side portions 120 and 130 are spaced apart by a first measure. In this position, the child 105 is awake and his head 106 is free to move in the forward direction and each side, limited, however, to a certain extent by the sides of the seat 104a and 104b of the headrest of the seat 104 .
[00146] As shown in Fig. 7F, the child 105 has fallen asleep and therefore the headrest 100 is in the downward position. In this position, the restraining member 140 is disposed in front of the forehead 107 of the child 105 in order to restrict the movement of the head 106 in the forward direction. Furthermore, the headrest member 110 is in its second state, in which its sides are spaced apart by a second measure, which is smaller than the first measure, thus restricting movement of the head 106 to the sides. This restriction by the restraining member 140 and by the sides of the headrest member 110 provides elevated stability and comfortable support of the head 106 while the child 105 sleeps. In particular, the restraining member 140 prevents the user's head 106 from falling forward, and the first and second side parts 120 and 130 prevent the user's head 106 from tipping to the left or right side. In addition, the above restriction can provide heightened head and neck stability to a user upon cornering, braking, or vehicle collision.
Reference is now made to Figs. 6A to 6F in order to explain in detail the structure and operation of the headrest 100 with the restraining member 140 in its upward position and the headrest member 110 in its first state.
[00148] The headrest member 110 has a back 112, a first side 120 and a second side 130. The back 112 and the first and second side parts 120 and 130 are formed as support pads for child's head 106. As shown in Fig. 6B, the rear portion 112 supports a rear portion 109 of the head 106.
[00149] The first side part 120 and the second side part 130 extend from the two opposite ends of the back part 112, i.e. a first end 113 and a second end 114, respectively. In addition, the first side portion 120 and the second side portion 130 are foldable relative to the central portion 112 between the first state (Figs. 6A to 6F) and the second state of the headrest member 110 (Figs. 7A to 7F). ).
[00150] The rear part 112 is fixed and integrated into the seat headrest 104 by means of stitching.
The restraining member 140 is configured with a first side member 150, a second side member 160 and a center member 142 disposed therebetween. The center member 142 is formed like a strap and, as shown in Fig. 6F, is disposed above the child's head 106.
[00152] The first side member 150 and the second side member 160 are secured to the central member 142 by means of ring and loop type fasteners. The ring and loop type fasteners allow adjustment of the length of the restraining member 140 in order to adjust the distance between the child's forehead and the restraining member 140 (in the descending position of the restraining member), the distance between the upper part of the head of the child. child and restraint member 140 (in ascending restraint position) and adjust headrest 100 to different head sizes.
[00153] In addition, the ring and handle type fasteners allow adjustment of the vertical location of the center member 142 in relation to the first and second side members 150 and 160. For example, if the user of the headrest 100 wants to use the center member 142 as a sleep mask, he can position center member 142 with respect to the first and second side members 150 and 160, so that center member 142 is located in front of his eyes rather than his forehead.
[00154] The central articulation of the restraining member 140 to the headrest member 110 is provided by articulating the first side member 150 to an outer face face 122 (shown in Fig. 8) of the first lateral part 120 by means of a first fastener by biasing 154 (shown in Fig. 8), and pivoting the second side member 160 to an outer face 132 of the second side portion 130, by means of a second biasing fastener 164.
[00155] The first side part 120 is configured with a first boundary channel 152 (shown in Fig. 8) formed on the outer face 122, and the second side part 130 is configured with a second boundary channel 162 formed on the outer face face 132. The first boundary channel 152 is formed within a channel element 151, which is mounted on the outer face 122. The second boundary channel 162 is formed within a channel element 161, which is mounted on the outer face 132 According to the particular example, the channel elements 151 and 161 of the outer faces 122 and 132 are related to a single element by being connected by a connecting strip (see Fig. 8).
[00156] The first fencing channel 152 and the second fencing channel 162 are arc-shaped, the length of which corresponds to the angle between the headrest member 110 and the restraining member 140 between their ascending and descending positions. According to the present example, this angle is approximately 120°.
[00157] As can be seen in Fig. 8, the first side member 150 is configured with a first protruding part 155, which is received and slidably displaceable within the first boundary channel 152 between the two extreme ends thereof by displacement of the limiting member 140 between its ascending and descending positions.
[00158] As shown in Figs. 6A and 6C, the second side member 160 is configured with a second projecting portion 165, which is received and slidably displaceable within the second enclosure channel 162 between a lower end 166 and an upper end 167 upon displacement of the restraining member 140 between the ascending and descending positions, respectively. The lower end 166 further restricts the upward rotation of the restraining member 140 beyond its upward position, and the upper end 167 further restricts the downward rotation of the restraining member 140 beyond its downward position, thus preventing, for example, the central member 142 is located below a predetermined level, for example, in front of the child's eyes.
[00159] The central member 142 is formed of a soft, flexible material. This material is rigid yet malleable. The headrest member 110 is formed from soft, flexible padding material. The first side member 150, the second side member 160, the two channel elements 151 and 161, are made of a hard, rigid, yet malleable plastic material. According to the present example, this material is polymer, and in particular, polypropylene.
[00160] It should be noted that, according to other examples, the headrest member 110 is not necessarily flexible, but, in any case, should allow the rotation of its sides.
[00161] As indicated above, the headrest member 110 is shown in Figs. 6A to 6F in its first state. In this state, the first side portion 120 and the second side portion 130 are spaced apart in a first measure by a distance D3 (Figs. 6B and 6D). the distance D3 is taken along an axis which is parallel to the axis of rotation X and traverses a center point 106' of the head 106. The first state of the headrest member 110 is in its normal state, to which the lateral parts of the headrest member 110 tends to reverse. The normal state is provided due to the geometry and structure of the headrest member 110.
[00162] The restraining member 140 is structured so that the distance between the first and second side members 150 and 160 is substantially constant during the rotation of the restraining member 140 between its ascending and descending positions. In view of this feature of the restraining member 140, and the fact that the distance between the first and second side members 150 and 160 is less than the distance between the outer faces 122 and 132 in the upward configuration of the restraining member 140, the displacement of the limiting member 140 from its ascending position to its descending position causes the headrest member 110 to assume its second state. This result is provided by the first and second side members 150 and 160, which flex the first and second side parts 120 and 130 with respect to the back 112, respectively, causing them to approach each other. Likewise, the displacement of the restraining member 140 from its descending position to its ascending position causes the headrest member 110 to assume its first normal state.
Reference is now made to Figs. 7A to 7F in order to explain in detail the structure and operation of the headrest 100 with the restraining member 140 in its downward position and the headrest member 110 in its second state.
[00164] As shown in Fig. 7B, in the downward position of the restraining member 140, its central member 142 is located in front of the forehead 107 of the child's head 106, and spaced therefrom such that a gap m' extends between the member. central 142 and forehead 107. Gap m' provides an extra measure of comfort to child 105, since when child 105 is awake there is no contact between forehead 107 and limiting member 140. it should not be too large in order to allow the restraining member 140 to operate effectively when contact is made between the forehead 107 and the central member 142. This contact can be established if the child's head 106 falls in the forward direction when he falls asleep.
[00165] Furthermore, as shown in Fig. 7B, the first and second sides 120 and 130 provide support to the sides 108 and 108' of the child's head (in Fig. 7B). The first and second side parts 120 and 130 further constitute a side impact protector for the user's head 106.
[00166] As indicated above, the headrest member 110 is shown in Figs. 7A to 7F in its second state. In this state, the first side portion 120 and the second side portion 130 are spaced apart by a second measurement represented by a distance D4 (shown in Figs. 7B and 7D), which is less than the distance D3. Distance D4 is taken along an axis that is parallel to the axis of rotation X and traverses the center point 106' of the head 106. As shown in Fig. 7B, the first and second side parts 120 and 130 are arranged close to the the user's temples, thus reducing the noise that approaches the child's ears and improving the quality of their sleep.
[00167] Distance D4 can be adjusted by changing the length of the limiting limb 140. For example, if the child feels discomfort with the first and second sides touching their ears, the length of the limiting limb 140 can be increased, increasing thus the distance D4.
