    DESCRIPTION

    Vehicle seat belt restraint system

     5
    OBJECT OF THE INVENTION

    The object of the present patent application is a retention system for a vehicle seat belt according to claim 1, which incorporates notable innovations and advantages. 10


    BACKGROUND OF THE INVENTION

    It is currently a fairly common problem in motor vehicles that the belt 15 is caught with the seat fixing mechanism in its reclined position. This situation commonly occurs after the rear seats of the vehicle are folded down. This may cause the user to not be able to remove the belt from its interlocking position, having to fold down the seats again, remove the belt from its position and recline the seat again. In addition, the belt may be damaged when caught with the fixing mechanism, which is detrimental for it to fulfill its functions and for its durability.

    In relation to this concept, it is known from the state of the art, as reflected in document US8308244, a vehicle seat that includes a seat back 25 mobilely connected to a base of said seat. The backrest is movable between a vertical position and a folded position. A stationary cross member is located on an outer side face of the seat back. Between the backrest and the naughty stationary is a dividing line. This dividing line is an imaginary line approximately in the space between the seat back and the stationary crossbar 30. A seat belt assembly has a tape and a tongue attached to the seat belt belt. When the backrest is in an upright position, the seat belt tape extends along the dividing line, the seat belt being in a condition of non-use. On the contrary, and without the use of the patent application, when the backrest is in the folded position and the seat belt in non-use condition, the tape would exceed the imaginary line. To do this, an apparatus arranged in the stationary crossbar retains the seat belt belt away from the dividing line, since the seat backrest moves between the vertical position and the folded position.

    The problem to be solved by said American patent consists more specifically in having either the stationary crossbar or the stationary crossbar as well as the safety belt, a retention means that prevents the belt of the safety belt from exceeding the imaginary line, with the seat back in its folded position. This prevents the seat belt belt from being trapped with the seat fixing mechanism in its vertical position. 10

    Thus, and as a summary, in said American document different alternatives of retention means are disclosed, such as:
    - a belt belt pin in the lower part of the stationary crossbar that forces the belt to deviate from the imaginary dividing line, 15
    - a protrusion in the upper part of the stationary crossbeam so that it is a difficulty for the belt to exceed the imaginary dividing line.
    - a magnet
    - a clip-like mechanism on the tongue and on the stationary crossbar to fix its position, and
    - two protrusions facing each other to fix the tongue. twenty

    At present, protrusions located in the upper part of the stationary crossbar or side lining adjacent to the back of the rear seat are commonly used. It is necessary to mention, however, that such a solution is not possible to implement when the belt, seen from the direction of advance of the vehicle, is overlapped with the franchise between seat and side covering. This situation occurs above all, in narrow vehicles (involving a narrow side covering) or in vehicles in which the design of said side covering is very curved. In both cases the bump does not work properly and does not prevent the belt from exceeding the imaginary line.
     30
    On the contrary, magnet type solutions, clip fixing mechanism type… require active user participation. In this way, each time the user wishes to fold the backrest of the rear seat, it is necessary to fix by means of these retention means the tongue or belt of the seat belt to the stationary crossbar. This operation is manual and inconvenient for the user, since in most cases it will not perform said previous anchoring between both components. Consequently, the present invention will not perform its function.

    It is also known from the state of the art, as reflected in EP1193142, a car seat that has a lever mounted on the front seat which retains the seat belt. This lever has a spring that forces it to be flush and folded to the side of the seat. Therefore, when the belt is not located on the lever, it closes towards its folded position.

    It is also known from the state of the art, as reflected in EP1415871, 10 a support for a vehicle seat belt that has a metal wire loop, with plastic coating, articulated to the side frame of the front seat of the access door. The retainer has a lock and release assembly with respect to a mounting foot. The retention device can be mounted on the seat so that the seat belt is kept in an inclined position. fifteen

    Both European documents solve a different problem, since they seek to guide and approximate the belt to the previous seat, especially in 3-door vehicles, facilitating that the user can comfortably reach the belt. Also note that the system is integrated in the front seat. twenty

    It is also known from the state of the art, as reflected in DE102013113568, a structure for a seat belt, which is capable of preventing the presence of noise caused by a tongue in the contact during driving with a side lining. Thus, a support structure for a seat is presented, in particular for a tongue of a rear seat during non-use of the seat belt. It is, therefore, a system to fix the tongue of the belt thus avoiding annoying noise in the cabin. Anyway, the user must manually fix the tongue each time to the retaining element, made nothing comfortable.
     30
    Thus, it is seen that there is still a need to have a solution of a seat belt restraint system in order to avoid being caught with the seat fixing mechanism in its reclined position, in particular after the operation of lower and then bring the backrest back to its original position.
     35

    DESCRIPTION OF THE INVENTION

    At present, and as mentioned, there is the problem that the belt is caught with the seat fixing mechanism in its reclined position, in particular in 5 the rear seats, after its folding, causing its interlocking, and possibly its deterioration. Therefore it is advisable to avoid the fall of the belt towards the slip, or interlocking element of the backrest, with the seat folded down. In particular, it is intended to avoid belt shear in the slip or interlocking mechanism, when a rear seat is unfastened. 10

    The invention of the retaining device would have basic characteristics of:
    - comprise a surface that unfolds, which retains the seat belt belt,
    - comprise a bump at one end of the surface to improve the retention of the belt,
    - understand an elastic means that forces the deployment of the device,
    - when the seat back is in a reclined position, said backrest forces the retaining device to be in a non-use position,
    - when the seat back is in the collapsed position, the retaining device is obliged to be in its position of use, thanks to the force exerted by the elastic means.

    Thus, and more specifically, the restraint system of a vehicle seat belt, where the vehicle comprises at least one backrest of a rear seat, where the at least one backrest is movable between a first reclined position and a second folded position. , at least one inner lining disposed on one side of the at least one backrest, where the at least one inner lining comprises at least one means for retaining the seat belt, wherein the at least one retaining means comprises a fastening wall and a first elastic means that pushes the clamping wall, from a first folded position, where the clamping wall is substantially flush with the at least one inner lining, the clamping wall being in contact with the at least one backrest of the rear seat , the at least one backrest being in a first reclined position, to a second deployed position, where the clamping wall it is protruding from the at least one inner lining, the at least one backrest being in a second collapsed position, so that the retaining wall retains the seat belt in a movement of the seat belt towards a space occupied by the at least one backrest in its first reclined position. The side interior lining of the passenger compartment of the vehicle, or pass-through lining, is therefore provided with a hinge-type mechanism, in order to fasten the belt in case of sneaking through the opening towards the trunk, in the event that the seat is folded down . It is important to note that the advantage that the present invention achieves is to fasten the belt in case it falls, making it impossible to reach the area of the slip, or mechanism for fixing the seat back in a reclined position, preventing the belt from being damaged. . Therefore, the belt is not necessarily prevented from being caught between the seat and the side lining, but it is prevented from reaching the lower area where said slip element 10 is.

    Thus, when the rear seat is in its second collapsed position, the retaining wall of the retaining means is not in contact with the rear seat, so that it is in its second deployed position. For this, the clamping mechanism, or retaining device 15, comprises first elastic means, preferably around the first axis of rotation that force the clamping wall to be in the removed position. Specifically, the at least one first elastic means of the clamping mechanism forces the clamping wall out of the inner lining or pass through a hole. Instead, when the seat is in a reclined position, the seat back 20 itself forces to the clamping mechanism, or retention device, to be introduced into the hole and remain inside the inner lining or pass-through, the first elastic means being compressed.

    On the contrary, when the rear seat is in its first reclined or use position, the retaining wall of the retaining means is in contact with the rear seat, so that it is forced to be in its first retracted position. In this non-use position, it is substantially flush with the inner lining. Thus, the retention device is inserted into the hole and remains inside the inner lining or pass-through, the first elastic means being compressed. 30

    Thus, rear seat means those seats of a vehicle that are adjacent to the trunk. Thus, when the backrest is down, there is a direct connection between the boot and the rear row of seats. This allows the user to increase the load capacity of their vehicle. Inner lining means a component, usually plastic, although it can also be textile, whose main function is to hide areas that should not be seen or manipulated by the user, improving the interior finish of the vehicle.

    More particularly, the at least one backrest comprises a support surface for a user, and at least a second surface substantially perpendicular to the support surface, where the at least one inner lining comprises a front wall arranged as an extension of the surface of support of the at least one backrest, and a side wall facing the at least one second surface of the at least one backing where the retaining wall of the at least one retaining means is comprised in the side wall of the at least one lining inside. In this way the restraint system is hidden when the seat is in its usual position, that is, with the backrest in its first reclined position. The main advantage that the clamping wall is fully included in the side wall of the inner lining is that it does not worsen the aesthetics of the interior of the cabin. In addition, in conditions of normal use of the vehicle, with a seat in the first reclined position, the mechanism is not seen, thus preventing the user from misusing the retention system of the present invention.

    Advantageously, the at least one retaining means comprises a first axis of rotation where the first elastic means produces a rotation of the clamping wall around the first axis of rotation, from the first position retracted from the clamping wall, where the wall clamping is flush with the side wall of the at least one inner lining and where the clamping wall is in contact with the at least a second surface of the at least one backrest, the at least one backrest being in the first reclined position, up to the second deployed position of the clamping wall where the clamping wall is protruding 25 from the side wall, the at least one backrest being in its second collapsed position. In this way the retention system is active or inactive, in line with the movement of the seat back. Thus, it is the second surface of the backrest itself that drives the inner wall into contact with the clamping wall. It is important to note that the user must not perform any additional operation of fixing the belt of the seat belt to the inner lining, as some of the state-of-the-art solutions do. The present retention system is autonomous and holds the belt belt without the user performing any operation.

    Further indicate that, preferably, the first axis of rotation is close to the front wall of the inner liner, so that it defines the direction in which the clamping wall is collapsed.

    More specifically, the rotation around the first axis of rotation from the first retracted position 5 to the second deployed position of the clamping wall is substantially 90 °. Therefore, the clamping wall in the second deployed position is substantially perpendicular to the side wall of the at least one inner lining. In this way the clamping wall is placed in an orientation substantially perpendicular to the path followed by the belt when it slides into the gap left by the back of the seat, once folded down. Being perpendicular, the retention efficiency of said clamping wall is maximized.

    According to another aspect of the invention, the clamping wall comprises at its furthest end of the first axis of rotation at least one projection so that the seat belt is retained in the clamping wall. Said projection helps considerably so that the belt does not exceed, in the passage of the back of the rear seat of a second position folded to a first reclined position, the clamping wall and is properly supported on it. It is thus understood that the belt is at least partially located between the seat back and the inner lining. Said at least 20 a projection prevents the seat belt from sliding and falling towards the interlocking or slipping mechanism. He is therefore forced to remain, at most, supported by the wall of support.

    In more detail, mention that this projection is intended to retain the belt once it has fallen and is secured by the clamping wall. Thus, once the user reclines the seat and, during said process, the second surface of the backrest of the rear seat pushes the clamping wall into the interior lining or pass-through, the belt would fall back into the bottom, without having any type of Effect the present invention. That is why, at the end of the clamping wall the projection 30 is located, for example in the form of ‘C ’, so that it is held in the clamping wall during the seat reclining process. Consequently, the belt follows this movement and is caught between the clamping wall and the second surface of the inner lining, when the seat back is in the first reclined position. Thus, the safety belt will be retained in an intermediate position without ever contacting the slip, avoiding possible damage to the belt.

    Further indicate that, preferably, the longitudinal projection is parallel to the first axis of rotation so that the retention effect of said projection is maximized. 5

    Advantageously, the projection comprises a groove in which one end of the seat belt is retained. Thus, this longitudinal projection has on the face facing the first axis of rotation of the groove, so that the retention effect is increased by adapting the shape of said groove to that of the narrow edge of the belt belt. 10

    In a preferred embodiment of the invention, the first elastic means is at least one spring integrated in the first axis of rotation. This ensures that the thrust is effected perpendicularly to the axis of rotation itself, which helps correct deployment and folding of the clamping wall. fifteen

    According to another aspect of the invention, the at least one retaining means comprises at least one end stop against the at least one inner lining, so that the clamping wall is retained in the second deployed position. A first alternative is to size the effort and application of said effort based on the mechanical characteristics of the first elastic means. Alternatively, the end-of-travel position is mechanically defined by the limit stop based on the reference of the inner liner.

    More specifically, the limit stop is a second wall linked to the clamping wall in the first axis of rotation, where the second wall is substantially perpendicular to the clamping wall.

    The mission of said second wall is that, in the position removed from the clamping wall, the opening inside the casing is closed. In addition, 30 improves the aesthetics of the assembly and prevents unwanted objects from entering the interior of the interior lining. In this way, the additional wall is flush with the side wall of the casing lining and the clamping wall is parallel to the belt. Additionally, said second wall acts as a stop against the inner wall of the inner lining or pass-through, holding the clamping wall in the extracted position thanks to the action of the first elastic means.

    To clarify the positions, when the backrest of the rear seat is in the second collapsed position, the stop is exerted by the second wall against the inner lining or 5 passages, the retaining wall being in the second position removed. On the contrary, when the seat back is in the first reclined position, the stop is exercised by the same seat back, which prevents rotation of the clamping wall, which is therefore flush with the side wall of the seat. Inner lining or passages in its first folded position. In this situation, the second wall exerts no stop 10 and is inside the inner lining or pass-through.

    Thus, the second wall is flush with the side wall of the inner liner and the clamping wall is substantially parallel to the belt, in the second deployed position. It should be noted that, for the mechanism to work, the clamping wall must be slightly smaller than the hollow of the inner lining and the second wall, in at least one of the dimensions, must be larger than said recess. This ensures that the retaining wall runs smoothly through the hollow of the inner lining, making only contact with the second surface of the backrest of the rear seat.
     twenty
    Advantageously, the at least one retaining means comprises at least one joining means between the clamping wall and the first axis of rotation, where the at least one retaining means comprises a second axis of rotation between the clamping wall and the less a joining means, where the clamping wall is capable of rotating around the second axis of rotation prolonging the rotation movement from the first retracted position 25 to the second deployed position. Said rotation is intended to prevent the breaking of said clamping wall. Thus, when the seat is folded down, it is usually because the user wishes to introduce large packages through the space or mouth of the rear seats. Since the clamping wall is a wall perpendicular to this opening, it is advantageous to provide said clamping wall with a rotational capacity in the event that an object introduced from the trunk pushes it in a vehicle forward direction, preventing it from breaking. Specify that by means of union any mechanism is understood that allows a mechanical link between the clamping wall and the first axis of rotation, thus being able to present the clamping wall of other types of movements than the rotation itself around the first axis of rotation . 35

    In a preferred embodiment of the invention, the at least one retaining means comprises at least one second elastic means exerting a force in the opposite direction to the movement of prolongation of the movement of rotation of the clamping wall, where the at least one means of union is a limit stop, so that it maintains the wall of support in the second position deployed before the force exerted by the at least a second elastic means. In this way the clamping wall is capable of rotating against the thrust of the second elastic means beyond the substantially perpendicular position with respect to the second flange by the action exerted by an element external to the system. In addition, due to the arrangement of the at least one joining means, the holding wall is capable of maintaining said perpendicular position by being supported against the at least one joining means.

    In a first alternative embodiment of the invention, the clamping wall and the second wall form a single solid element, so that it is possible to obtain, at least in part, the advantages of the main embodiment described so far, with a design more simplified and lower cost of realization.

    Thus, a solid body can be made so that the user can no longer break the clamping wall by introducing a bulge by pushing on the back. An alternative 20 would be to convert it into a solid body, and with an inclined wall, therefore, without any wall perpendicular to the force that the user could apply when introducing a body through the trunk, therefore there is no possibility of breaking the assembly.

    According to another aspect of the invention, the first clamping wall is additionally comprised in the front wall of the at least one inner lining so that the clamping wall comprises an angular shape formed by at least a first essentially flat section and a second section essentially flat. A second alternative embodiment is thus achieved where it is sought to compensate for the inclination of the inner lining or passages that the belt drives towards the opening of access to the trunk, such that a kind of wedge is formed between inner lining or passes, and the wall of support that allows to retain the belt when the seat is in a collapsed position.

    More specifically, and according to a second alternative embodiment, the angular-shaped clamping wall is deployable around the first axis of rotation from the first folded position 35, where the first essentially flat section is flush with the front wall of the at least one inner lining. and the second section is flush with the side wall of the at least one inner lining, the second section being in contact with the second surface of the at least one backrest, the at least one backrest being in a first reclined position, to the second deployed position , where the second section 5 is projecting from the side wall of the at least one inner lining and the first section is inclined with respect to the front wall of the at least one inner lining, the at least one backrest being in a second collapsed position, so that the first section of the retaining wall retains the seat belt in a safety belt movement ad towards a space occupied by the at least one backrest in its first reclined position 10.

    Thus, the clamping wall also has a movement between a first position and a second position. In the first position it is substantially flush with the inner lining or passages, forming a contiguous surface with said lining. Similarly, it also has a spring system that seeks to extend the fastening system from the flush position to a use position. Therefore, also in this second alternative, when the seat moves from a reclined position to a collapsed position, the clamping wall ceases to meet the resistance in the seat back, moving from the first flush position to the second deployed position. twenty

    Specifically in this alternative, the clamping wall is not only in the side wall of the inner lining or pass-throughs (the one that contacts the seat) but also part of the seen or front surface of the inner lining or pass-throughs. The advantage of this system is that it prevents the belt from falling into the hole and being pinched. Thus, the main alternative poses a situation in which it is not specifically avoided that the belt is caught between the seat and the lining, but the belt is prevented from contacting the rear seat backrest fixing mechanism that could damage it. In this additional alternative, it is intended that the belt no longer falls into the franchise between the seat and interior lining or passages, always being visible to the user.

    According to another aspect of the invention, the angular-shaped clamping wall comprises at the far end of the first axis of rotation of the second section an extension towards an interior of the at least one inner lining, where the extension performs an end stop function 35 running against the side wall of the at least one inner lining retaining the clamping wall in the second deployed position, so that an end-of-stroke position is established while, in a specific embodiment, the hole that is left in the inner lining.
     5
    Thus, and mainly for decorative purposes, the belt support wall is accompanied by a set of adjoining walls that close the open spaces in the position of use. In this way the user does not see holes or empty areas in the inner lining or passages.
     10
    Note that in this alternative embodiment, the first elastic means is also at least one spring integrated in the first axis of rotation.

    The attached drawings show, by way of non-limiting example, a restraint system for a vehicle seat belt, constituted according to the invention. Other features and advantages of said restraint system for a vehicle seat belt, object of the present invention, will be apparent from the description of a preferred, but not exclusive, embodiment illustrated by way of non-limiting example in the accompanying drawings, in which:

    DESCRIPTION OF A PREFERRED EMBODIMENT 30

    In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below. 35
    The problem that is intended to be solved in the present invention is that shown in Figure 2, where the behavior of a seat belt 1 is observed when the backrest 21 of a rear seat 2 is between a first reclined position and a second folded position. Thus, in a reclined position, the safety belt 1 rests on both the backrest 21 and the inner lining 3. On the contrary, when the backrest 21 5 is lowered, the safety belt 1 finds no support from said backrest 21 , so it occupies the space occupied by the backrest 21. This situation is dangerous since the safety belt 1 can contact the backrest fastening mechanism 21 of the rear seat 2, so that it can be damaged. Therefore, as can be seen in Figure 1, the present invention raises a retaining means 4 located in the interior lining 3 of the vehicle. Its main function is to fasten the seat belt 1 preventing it from contacting the backrest fastening mechanism 21.

    Thus, as seen in Figure 3B, thanks to the retention mechanism 4 of the present invention, the seat belt 1 is fastened by said retention mechanism 4 and away from the backrest fixing mechanism 21 of the rear seat 2 .

    Thus, as seen in Figures 4A and 4B, the invention relates to a restraint system for a vehicle seat belt 1, wherein the vehicle comprises at least one backrest 21 of a rear seat 2, where the at least a backrest 21 is movable between 20 a first reclined position and a second folded position, at least one inner lining 3 arranged on one side of the at least one backing 21, where the at least one inner lining 3 comprises at least one retaining means 4 of the seat belt 1, wherein the at least one retaining means 4 comprises a clamping wall 41 and a first elastic means 45 that pushes the clamping wall 41, from a first folded position, where the clamping wall 41 is substantially flush with the at least one inner lining 3, the clamping wall 41 being in contact with the at least one backrest 21 of the rear seat 2, the at least one backrest 21 being in a p rimera reclining position, to a second deployed position, where the clamping wall 41 is protruding from the at least one inner lining 3, the at least 30 backrest 21 being in a second collapsed position, so that the clamping wall 41 retains the seat belt 1 in a movement of the seat belt 1 towards a space occupied by the at least one backrest 21 in its first reclined position.

    More particularly, as seen in Figures 1, 4A and 4B, the at least one backrest 21 comprises a support surface 211 for a user, and at least a second surface 212 substantially perpendicular to the support surface 211, where the at least one inner lining 3 comprises, a front wall 31 arranged as an extension of the support surface 211 of the at least one backrest 21, and a side wall 32 arranged 5 facing the at least a second surface 212 of the at least one backrest 21, wherein the clamping wall 41 of the at least one retaining means 4 is comprised in the side wall 32 of the at least one inner lining 3.

    According to another aspect of the invention, as seen in Figures 4A and 4B, the at least 10 a retaining means 4 comprises a first axis of rotation 44 where the first elastic means 45 produces a rotation of the clamping wall 41 around of the first axis of rotation 44, from the first position retracted from the clamping wall 41, where the clamping wall 41 is flush with the side wall 32 of the at least one inner lining 3 and where the clamping wall 41 is in contact with the at least one second surface 212 15 of the at least one backrest 21, the at least one backrest 21 being in the first reclined position, to the second deployed position of the clamping wall 41 where the clamping wall 41 is protruding from the wall lateral 32, the at least one backrest 21 being in its second collapsed position.
     twenty
    On the other hand, as seen in Figures 4A and 4B, the rotation around the first axis of rotation 44 from the first retracted position to the second deployed position of the clamping wall 41 is substantially 90 °. Thus, in the second deployed position the first retention tab 41 is substantially perpendicular to how it is in the first retracted position. The first flange 41 is substantially parallel to the side wall 25 of the frame 3 in its retracted position.

    More particularly, as seen in Figure 5, the clamping wall 41 comprises at its end 412 furthest from the first axis of rotation 44 at least one projection 413 so that the seat belt 1 is retained in the wall of clamping 41. 30

    Additionally, as seen in Figure 5, the projection 413 comprises a groove 414 in which one end of the seat belt 1 is retained. In particular, the projection with the groove has a C or L shape.
     35
    More specifically, as seen in Figures 4A, 4B, 6A and 6B, the first elastic means 45 is at least one spring integrated in the first axis of rotation 44.

    According to a preferred embodiment of the invention, as seen in Figures 4A, 4B, 6A and 6B, the at least one retaining means 4 comprises at least one end stop 5 against the at least one inner lining 3, of so that the clamping wall 41 is retained in the second deployed position.

    According to another aspect of the invention, as seen in Figure 5, the limit switch is a second wall 42 linked to the clamping wall 41 on the first axis of rotation 10 44, where the second wall 42 is substantially perpendicular to the clamping wall 41.

    Therefore and as a summary of this first embodiment, it is shown in Figure 4A, which corresponds to a section in a horizontal plane of Figure 3A, the backrest 15 21 of the rear seat 2 in its first reclined position. In this position, the backrest acts as a stop and keeps the clamping wall 41 flush with the side wall 32 of the inner lining 3. On the other hand, the second wall 42 does not perform any function. On the contrary, as shown in Figure 4B, the backrest 21 is in the second collapsed position. Since the clamping wall 41 does not encounter any resistance, the first 20 elastic means 45 exert a force such that they produce a rotation of the clamping wall 41 around the first axis of rotation 44, removing the clamping wall 41 from the hollow of the inner lining 3. This turn is stopped by the second wall 42 of the retaining means 4, which runs into the side wall 32 of the inner lining 3 and forces the clamping wall 41 to remain in the second deployed position. Due to the perpendicular arrangement of the clamping wall 41 in relation to the second wall 42, the clamping wall 41 is parallel to the belt of the seat belt 1. Note that the position can be easily modified by the relative position between the clamping wall 41 and the second wall 42 to adapt to the construction characteristics of the interior of the vehicle. It is therefore intuited that, when the backrest 21 recovers its first reclined position, it will push the clamping wall 41 into the hollow of the inner lining 3, overcoming the force of the first elastic means 45.

    On the other hand, as seen in Figures 6A and 6B, the at least one retaining means 4 comprises at least one joining means 43 between the clamping wall 41 and the first axis of rotation 44, where the at least a retaining means 4 comprises a second axis of rotation 46 between the clamping wall 41 and the at least one connecting means 43, where the clamping wall 41 is capable of rotating around the second axis of rotation 46 prolonging the rotation movement from the first stowed position to the second deployed position. 5

    According to a preferred embodiment of the invention, as seen in Figures 6A and 6B, the at least one retaining means 4 comprises at least one second elastic means 47 that exerts a force in the opposite direction to the prolongation movement of the rotational movement of the clamping wall 41, where the at least one connecting means 43 is a running end stop 10, so that it maintains the clamping wall 41 in the second position deployed before the force exerted by the at least a second elastic means 47, so that an angle between the clamping wall 41 and the second wall 42 is likely to increase.
     fifteen
    Thus, it is intended to provide a solution that prevents breakage of the retention system of the present invention before a force applied from the trunk of the vehicle with the loading of an object through the opening of the rear seats with at least one backrest 21 in the second position dejected. As can be seen in Figure 6B, a second axis of rotation 46 allows a rotation of the clamping wall 41 in the direction of application of said force. The second deployed position of the clamping wall 41 is maintained thanks to the force exerted by a second elastic means 47 and the stop exerted between the joining means 43 and the clamping wall 41. Note that at all times, the second wall 42 continues to abut the side wall 32 of the inner lining 3, as well as the first elastic means 45 exerts a continuous force on the clamping wall 41. 25

    According to a first alternative embodiment of the invention, as seen in Figure 7, the clamping wall 41 and the second wall 42 form a single solid element, so that the surface of the material that joins the clamping wall 41 and the Second wall 42 is substantially inclined in the thrust direction of a package that is inserted into the passenger compartment from the trunk. Said alternative allows saving the second axis of rotation 46, as well as the second elastic means 47. The same effect is achieved by designing a single body formed by the clamping wall 41 and the second wall 42 so that no surface is perpendicular to the direction of force application. Thus, there will be no element of the retaining means 4 that opposes said force. 35

    According to a second alternative embodiment of the invention, as seen in Figures 8A and 8B, the first clamping wall 41 is additionally comprised in the front wall 31 of the at least one inner lining 3 so that the clamping wall 41 comprises an angular shape formed by at least a first section 415 essentially flat and a second section 416 essentially flat.

    More particularly, as can be seen in Figures 8A, 8B and 10C, the angular wall 41 is deployable around the first axis of rotation 44, from the first retracted position, where the first essentially flat section 415 is flush with the front wall 31 of the at least one inner lining 3 and the second section 416 is flush with the side wall 32 of the at least one inner lining 3, the second section 416 being in contact with the second surface 212 of the at least one backrest 21, the at least one backrest 21 being in a first reclined position, to the second deployed position, where the second section 416 is protruding from the side wall 32 of at least 15 an inner lining 3 and the first section 415 is inclined with respect to the front wall 31 of the at least one inner lining 3, the at least one backrest 21 being in a second collapsed position, so that the first section 415 of the clamping wall 41 withdraws ne the seat belt 1 in a movement of the seat belt 1 towards a space occupied by the at least one backrest 21 in its first reclined position. twenty

    More specifically, as can be seen in Figure 8B, the angular-shaped clamping wall 41 comprises at the end 412 furthest from the first axis of rotation 44 of the second section 416 an extension 417 towards an interior of the at least one inner lining 3 , where the extension 417 performs a limit stop function against the side wall 32 of the at least one inner lining 3 retaining the clamping wall 41 in the second deployed position.

    Thus, a second embodiment is presented where the clamping wall 41 is formed not only by a first section 415 that fits with the side wall 32 of the inner lining 3, 30 but also by a second section 416 that fits with the front wall 31 of the inner lining 3.

    In order to improve understanding of the effect produced by the restraint system of a vehicle seat belt 1 of the present invention, Figure 10A shows in detail how the seat belt 1 is clamped between the seat backrest 21 rear 2, the backrest 21 being in its first reclined position, and the slide or fixing mechanism of said backrest 21 to the vehicle body.

    To avoid the situation in Figure 10A, an embodiment 5 shown in Figure 10B has been described, where the clamping wall 41 is only comprised in the side wall 32 of the inner lining 3 and, thanks to the action of the projection 413 it is possible to retain the seat belt 1 between the backrest 21 and the inner lining 3. Therefore, the seat belt 1 is not prevented from being slightly anchored between both elements, but any possibility of the seat belt is eliminated safety 1 10 contact the backrest fixing mechanism 21 that may damage you.

    Alternatively, as shown in Figure 10C, a second alternative embodiment has been described where the clamping wall 41 is comprised between the side wall 32 and the front wall 31 of the inner lining 3 and, thanks to the angle or inclination 15 forming the clamping wall 41 with the front wall 31, the seat belt 1 is not caught between the backrest 21 of the rear seat 2 and the inner lining 3.

    The details, shapes, dimensions and other accessory elements, as well as the components used in the implementation of the restraint system of a vehicle seat belt may be conveniently replaced by others that are technically equivalent, and do not depart from the essentiality of the invention or of the scope defined by the claims that are included after the following list.
