    [031] Referring to Figures 1-17B, reference number 9 generally designates a vehicle that has a vehicle seat assembly 10 that includes a lower backrest 12. An upper backrest 14 is operatively coupled to the lower backrest 12. The upper backrest 14 is pivotally mounted on the lower backrest 12 on a geometric axis of pivot 16. An arched rear support bar 18 is arranged on the upper backrest 14 and is configured to rotate the upper backrest 14 between front and rear positions. The rear arcuate support bar 18 includes first and second generally linear members 20, 22 and an intermediate arcuate portion 24 disposed between the first and second generally linear members 20, 22. A hinge assembly operatively couples the backrest 12 below the upper backrest 14.
    [032] Referring again to Figure 1, the illustrated vehicle seat assembly 10 is configured for use on a vehicle of any type, which includes, without limitation, cars, vans, trucks, buses, etc. The vehicle seat assembly 10 is suspended on rails that allow the movement of the vehicle seat assembly 10 in front and rear directions. In addition, the vehicle seat assembly 10 may include a variety of comfort controls, which includes, for example, thigh support using chocks
    6/18 independent thigh 30, lumbar support and upper thoracic support. The vehicle seat assembly 10 includes a head restraint 32 which is arranged on the top backrest 14. Head restraint 32 is movable between front and rear positions to accommodate passenger heads of various sizes, as well as different passenger heights. The vehicle seat assembly 10 also includes controls specifically configured to adjust an upper thoracic portion 34 of the upper backrest 14.
    [033] Referring to Figure 3, the vehicle seat assembly 10 includes a backrest assembly 48 with a backrest suspension system 50 supported on a frame 52. Frame 52 of the backrest assembly 48 of the vehicle seat assembly 10 includes a first side support 54 and a second side support 56 that define the frame 52. The first and second side supports 54, 56 of the frame 52 pivotally engage a rear portion of a seat 60 and extend upwardly from the seat 60 to a top portion of the backrest assembly 48 and connect to an upper side clamp 62. The upper side clamp 62 of the backrest assembly 48 extends between the first and second side supports 54, 56. Head restraint 32 is coupled operatively to the upper side clamp 62 of the backrest assembly 48 and is substantially centered between the first and second side supports 54, 56. The upper side clamp 62 as well as a clamp the lower side 64 of the backrest suspension system 50 is coupled to and are distributed between the first and second side supports 54, 56, such that the backrest suspension system 50 is generally positioned between the head restraint 32 and seat 60 to support a passenger's back. It is contemplated that the head restraint 32 may be integrated into the top portion of the backrest assembly 48 or that the head restraint 32 may otherwise not be included in the vehicle seat assembly 10.
    [034] Referring again to Figure 3, the first and second side supports 54, 56 extend upward from a support
    7/18 reclining core 66 which has a reclining core 67 that pivotally couples the backrest assembly 48 to seat 60. The first and second side supports 54, 56 are substantially parallel to each other and curl up and back from of the reclining core support 66 to provide a curved shape that complements the shape of a passenger's spine. In addition, the first and second side supports 54, 56 are thicker and more robust adjacent to the reclining core support 66 and taper as they extend upwards to mate with the upper side bracket 62 which extends orthogonally between the first and second supports 54, 56. The upper side bracket 62 of frame 52 includes connectors 68 for securing the head restraint 32 to a central portion of the upper side bracket 62 centrally between the first and second side supports 54, 56. Connectors 68 are defined by upwardly designed flaps configured to engage the head restraint 32.
    [035] Referring again to Figures 3 to 7, the lower backrest 12 of the backrest suspension system 50, as shown in Figure 3, includes flexing members 70 that extend from each of a first side connector 71 and a second side connector 73 of the backrest assembly 48. The first and second side connectors 71, 73 are operably coupled to and support side shims 69 (Figure 2). The lower backrest 12 is positioned adjacent to the seat 60 and includes a lower comfort support 74 that supports the lower back of a passenger. Similarly, the upper backrest 14 of the backrest assembly 48 has an upper comfort support 75 operatively coupled to a curved flexing member 76 operatively coupled to the arched rear support bar 18. The flexing member 76 of the clamp upper side 62 is disposed above the first and second side connectors 71, 73. Bending member 76 includes a recess 77 in a top portion thereof configured to properly separate bending member 76 from head restraint 32. The
    8/18 bending member 76 also includes a plurality of outwardly extending reinforcing flanges 81. The curved bending member 76 includes three connection features 83 that function as pressure engagement connection arrangements for securing comfort support upper 75 on the curved flexing member 76. In the illustrated embodiment, the arched rear support bar 18 is coupled to the flexing member 76 by means of a friction engagement. Other connection provisions are also contemplated. It is conceivable that the lower and upper backrests 12, 14 can be integrated in a single component or in several components distributed by the backrest assembly 48.
    [036] The flexing member 76 of the upper backrest 14 of the backrest suspension system 50, as shown in Figures 4 to 7, generally defines a support basket that supports the upper back of a passenger. The flexing member 76 of the upper side clamp 62 is coupled to the arched rear support bar 18 that extends laterally between the first and second side supports 54, 56 of the frame 52. The arched rear support bar 18 is pivotally coupled with respect to the pivot pins 92 to allow the bending member 76 to pivot back and forth around the pivot geometry axis 16. Additionally, the arched rear support bar 18 is operably coupled to a motor 94 via a connection 96 to rotate the arched rear support bar 18 in an adjustable manner. Consequently, the upper backrest 14 can be pivoted back and forth in relation to a plurality of angled positions in relation to the lower backrest 12 and frame 52, as described in more detail below.
    [037] Referring again to Figures 3-6, pivot pins 92 generally define the geometric axis of pivot 16. The upper backrest 14 includes a front pivot portion 100 which is operatively coupled to the lower backrest 12. More specifically , the front pivot portion 100 is pivotally mounted on the lower backrest 12 on the pivot geometry axis
    9/18
    16. The arched rear support bar 18 is arranged on the upper backrest 14 and configured to rotate the upper backrest 14 between the front and rear positions. The arched rear support bar 18 includes a generally U-shaped configuration. The first and second generally linear members 20, 22 and the arched intermediate portion 24 generally define a central open space 102 in the backrest assembly 48. A hinge assembly 110 operationally engages the front pivot portion 100 of the upper backrest 14 to the backrest assembly 48 and allows movement between the front and rear positions. Notably, the flexing member 76 or support basket can be attached to the arcuate intermediate portion 24 of the arcuate rear support bar 18 or it can be overmoulded directly onto the arcuate intermediate portion 24. The arcuate rear support bar 18 is connected to the supports 112 extending forward with respect to the first and second generally linear members 20, 22 of the rear arched support bar 18. The rear arched support bar 18 is configured to rotate around a front portion of the supports 112 on the pivot pins 92 Consequently, the entire backrest 14 can be rotated around a front portion of the supports 112.
    [038] The backrest suspension system 50, as shown in Figure 3, includes frame 52, which can be constructed of metal or other rigid material and a rigid rear panel 120 configured to substantially surround a rear portion of frame 52. A vehicle seat assembly 10 also includes a front cutout panel 130. Front cutout panel 130, together with the rigid rear panel 120, generally defines a housing that covers frame 52 of the backrest assembly 48. The rigid rear panel 120 is engages frame 52 to substantially surround a rear portion of frame 52. Similarly, the front cutout panel 130 engages a front portion of frame 52 to surround a top front portion of frame 52. The front cutout panel 130 includes a mounting cut 133 to accommodate the head restraint 32, which extends through the same
    10/18 to couple with upper side bracket 62 of frame 52. Front cutout panel 130 and rigid rear panel 120 also engage frame 52 adjacent to upper side bracket 62, first side bracket 54 and second side bracket 56 , substantially surrounding an edge portion of frame 52. Front cutout panel 130 and rigid rear panel 120 are typically molded with a polymeric material and frame 52 is constructed substantially of steel, aluminum or another substantially rigid metal. It is conceivable that alternative training materials or methods can be used for the frame and frame 52. In addition, the frame, or portions thereof, can conceivably be integrated into frame 52.
    [039] Referring again to Figure 3, the upper backrest 14 and the lower backrest 12 of the backrest suspension system 50 are configured to operationally couple to a passenger cushion assembly 140. More specifically, the flexing members 70, 76 in the lower backrest 12 and in the upper backrest 14, respectively, extend forward to engage and support a passenger's back. The passenger cushion assembly 140 includes the lower comfort support 74, the upper comfort support 75, a cushion assembly 142 and a blanket 144. Flexing members 70, 76 operationally couple to the lower comfort support 74 and the superior comfort support 75 in a press fit and friction fit arrangement. The cushion assembly 142 is arranged between the lower comfort support 74 and the upper comfort support 75 and the blanket 144 and between the lower comfort support 74 and the blanket 144. It is conceivable that the passenger pillow assembly 140 may include more or less layers between the blanket 144 and the upper comfort support 75. Additionally, it is conceivable that the passenger cushion assembly 140 can be an integral part with the flexing members 70, 76 of the backrest suspension system 50.
    [040] As shown in Figure 3, the bending members 70 include three connection features 150 arranged longitudinally and in alignment with
    11/18 complementary features in the first and second side connectors 71, 73 of the lower back 12 to secure the flexing members 70 of the lower back 12 in the passenger cushion assembly 140. The flexing members 70 of the lower back 12 extend forward and out of the backrest assembly 48 to create an outer peripheral gap 152. The pivot pins 92 pivotally engage the first and second side connectors 71, 73, generally above the lower side clamp 64.
    [041] Referring now to Figures 3-5, the top backrest 14 is pivotable back and forth around the geometric axis of pivot 16. Motor 94 is operationally coupled to the arched rear support bar 18 and configured to rotatably adjust the arched rear support bar 18 and the upper portion of the passenger cushion assembly 140 back and forth with respect to the lower portion. Link member 96 operationally couples motor 94 to the end of the rear arcuate support bar 18. The link member 96 can include a direct gear connection between motor 94 and the rear arcuate support bar 18. Alternatively, the upper portion of the passenger cushion assembly 140 and, specifically, the flexing member 76, can alternatively be pivoted through a manual gear assembly, as discussed in further details in the present invention. The upper portion is pivoting between a front position, a rear position and several intermediate positions between them. When the upper backrest 14 is in the rear position, the upper segment of the passenger support is substantially aligned with the backrest structure as a whole, as shown in Figure 8. As the upper backrest 14 moves to the intermediate positions and additionally to the forward position, the upper segment of the passenger support tilts forward to provide additional support for a passenger's neck (see Figure 9). Consequently, the outer peripheral span 152 expands adjacent to the upper backrest 14 as the flexing member 76 pivots forward to the forward position. It is contemplated that the
    12/18 vehicle seat assembly 10 can be configured to optionally pivot the top backrest 14 from the rear position to the intermediate positions and additionally to the front position simultaneously as the backrest assembly 48 reclines from a vertical position to a reclined position in relation to the seat 60.
    [042] As shown in Figure 4, the vehicle seat assembly 10 includes an engine clamp 180 that operatively couples engine 94 to backrest assembly 48. A lower end of link member 96 connects to engine 94 and a the upper end connects to a pivot junction 182, where the arched rear support bar 18 is coupled to the supports 112. Notably, the arched rear support bar 18 and, consequently, the upper backrest 14, rotates around the geometric axis of pivot 16 located through a front portion of support 112. Link member 96 is coupled to a worm gear that is operatively coupled to motor 94. Motor 94 operates to drive link member 96 up or down down based on the rotational direction of the 94 engine. It is conceivable that the 94 engine can be replaced by a manually rotating button to make the upper component pivot around the rear arched support bar 18. Add It is conceivable that several alternative connection arrangements, such as those that include a Bowden cable, can be used to rotate the arched rear support bar 18 and pivot the upper backrest 14.
    [043] Referring now to Figure 10, it is also contemplated that the upper backrest 14 can be adjusted manually instead of by an automated or motorized system. In the illustrated embodiment, the arched rear support bar 18 is pivotally coupled to one of the first and second generally linear members 20, 22 and a first linear end is pivotally coupled to a manual hinge assembly 200 that is manually adjustable and configured to secure or lock the top backrest 14 in a variety of positions in relation to the backrest
    Lower 13/18 12.
    [044] As shown in the embodiment illustrated in Figures 11-13, the manual hinge assembly 200 includes a housing 204 that has flesh engaging teeth 206 disposed on an inner wall 208 thereof. A positional cam 210 is arranged inside the housing 204 and includes complementary cam teeth 212 configured to engage the cam engaging teeth 206 of the cam 204. The cam 204 includes a cam groove 214 and a member cam channel spring 220 moving within the elongated groove 214 to adjust the position cam 210 in a vertical direction within the housing 204. The cam channel spring member 220 extends around a guide axis. A meat return spring 222 is coupled to a flap 224 at one end of the meat and configured to rotate the positional meat 210 to a rear or zero degree position within housing 204. The elongated groove 214 extends vertically through an intermediate portion of the housing 204. A positioning pin 230 extends into the elongated groove 214 which extends through the housing 204 and is linearly slidable in the meat channel. The positioning meat pin 230 extends through the positioning meat 210 and is operatively coupled to one of the first and second generally linear members 20, 22 of the vehicle seat assembly 10. The meat channel spring member 220 forces the meat pin 230 and, consequently, the meat position 210, upwards such that the meat engagement teeth 206 are engaged with the meat teeth 212. To rotate the meat position 210 inside the housing 204, a user would push a lever coupled to the meat pin 230 downward to disengage the teeth of the meat 212. In use, the manual hinge assembly 200 is in a design position with the meat 210 positioned in a completely rear position within housing 204. In that position, the the meat 212 teeth are in a completely rear position and engaged with the meat engaging teeth 206 on the inner wall 208 of the
    14/18 housing 204 (see Figure 14). A guide groove generally in square shape 240 is disposed in an upper portion of the positional cam 210. The guide groove in square shape 240 includes a guide pin 242 which extends therethrough. The guide pin 242 moves around the square-shaped guide groove 240 and helps to guide the positioned meat 210 as the positioned meat 210 rotates from a completely rear position to several intermediate positions and finally ends or stops in a completely position forward. Guide pin 242 rotates around a center island 244 that helps guide pin 242 along the square-shaped guide slot 240. Guide pin 242 will rest in any of a variety of positions along the bottom portion of the slot square shaped guide 240.
    [045] Referring now to Figures 14A and 14B, in one embodiment, to affect the movement of the upper backrest 14 forward, a lever on an outer periphery of the vehicle seat assembly 10 that is coupled to the positional cam 210 is lowered. such that the teeth of the meat 212 of the meat positioned 210 disengage the meat engaging teeth 206 on the inner wall 208 of the housing 204. The arched rear support bar 18 can be spring-oriented to a front position and made possible to move by a predetermined distance forward in relation to the backrest assembly 48. Then the teeth of the meat 212 of the meat are allowed to position 210 re-engage the teeth of the meat engagement 206 as the passenger allows the meat to position 210 to move again to an elevated position. Notably, the meat channel spring member 220 of the manual hinge assembly 200 has a stronger compressive force than the tension force of the meat return spring 222. Consequently, with the absence force applied by a passenger, the positional meat 210 will remain in the raised position. Additionally, it will be understood that the meat return spring 222 is designed to rotate the positioning meat 210 backwards into the housing 204. After the meat engaging teeth 206 re15 / 18 engage the cam teeth 212 on the inner wall 208 of the housing 204, the upper backrest 14 is now in an intermediate front position. This same movement can be repeated to move the backrest to another intermediate front position, or finally, to a completely forward position, as shown in Figure 17. It is contemplated that the cam 210 can be positioned in the design position (Figure 14) and be movable to a rear intermediate position of approximately 5 degrees (Figure 15), a front intermediate position of approximately 10 degrees (Figure 16) and a completely forward position of approximately 15 degrees (Figure 17). It will be appreciated by an element of common knowledge in the art that the amount of slope may differ, depending on the intended use. The aforementioned inclination angles are intended to be examples only.
    [046] Referring again to Figures 14-17B, the manual hinge assembly 200 may include a ratchet system that functions as follows. Initially, as shown in Figures 11 and 14, the upper backrest 14 is in a design position at zero degree inclination in relation to the backrest assembly 48. From that position, a user can hold the upper backrest 14 and incite the backrest upper 14 forward in relation to the backrest assembly 48 such that the upper backrest 14 becomes inclined in relation to the backrest assembly 48. As the upper backrest 14 is rotated forward, the cam teeth 212 begin to engage the ratchet forward. Figure 15 illustrates the teeth of cam 212 moving forward to a position with respect to cam engaging teeth 206 such that the upper backrest 14 is now in a predetermined position, for example, five degrees forward, relative to to the backrest assembly 48. The user can continue to incite the upper backrest 14 forward to the additional inclined positions (for example, 10 degrees (Figure 16)), or to a maximum inclination angle of the upper backrest 14 in relation to the assembly backrest 48 as shown in Figure 17 (for example, 15 degrees).
    16/18 [047] Referring again to Figures 11-17, once the user has engaged the ratchet on the upper backrest 14 to the frontmost position in relation to the backrest assembly 48, the user cannot additionally incite the upper backrest 14 for any additional point ahead. To return the upper backrest 14 to the design position or zero degree, the user simply incites the upper backrest 14 further forward from the furthest forward position as shown in Figure 17, such that the meat positioned 210 is urged downward by a front slope 250 disposed adjacent to the meat coupling 206 of housing 204 against upward spring orientation of the meat channel spring member 220. Since the meat teeth 212 disengage from the meat coupling teeth 206, the meat return spring 222 rotates the meat position 210 backwards in a clockwise direction in the direction of arrow A, thereby resetting the meat position 210 within housing 204 back to the design position or zero degree. The process can then be started again. The user can move the upper backrest 14 to a desired angled position in relation to the backrest assembly 48.
    [048] It will be understood by an element of common knowledge in the art that the construction of the described disclosure and other components is not limited to any specific material. Other exemplary embodiments of the disclosure disclosed in the present invention can be formed from a wide variety of materials, unless otherwise described in the present invention.
    [049] For purposes of this disclosure, the term coupled (in all its forms, coupling, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to each other. Such a junction can be stationary in nature or mobile in nature. Such a junction can be achieved with the two components (electrical or mechanical) and any additional intermediate members that are integrally formed as a single unitary body with each other or with both
