Description

[0001] DESCRIPTION

[0002] TITLE: Layout for vehicle opening with locking means keeping the opening closed in case of impact.

[0003] The present invention relates to an arrangement for a vehicle opening. The invention also relates to an opening comprising such an arrangement. The invention further relates to a vehicle comprising such an arrangement or such an opening. Finally, the invention relates to a method of operating such a vehicle, such an opening, or such an arrangement.

[0004] A vehicle, particularly a motor vehicle, according to the prior art is generally equipped, especially on each side door, with an external side door opening control, for example, a handle. The external opening control is usually mounted on an exterior panel of the door in question. Activating this external opening control generally results, via a pivoting lever winding a cable, in the engagement of a lock, thereby opening the door.

[0005] Only in the event of an impact, particularly a side impact on the door, does the outer door panel deform inwards due to the compression generated by the impact. The exterior door handle is then brought closer to the lock until it makes contact. During this compression, due to inertia, the operating lever rotates around its pivot point. This rotation winds the lock's activation cable, which is equivalent to manually operating the exterior door handle and results in the door opening unintentionally.

[0006] Thus, although the external opening command was not activated, the door opened unintentionally, which is dangerous and contrary to regulatory requirements. The vehicle cannot be sold in this condition. Indeed, a door deformed by an impact must remain closed to ensure its function of protecting the vehicle's occupants.

[0007] The aim of the invention is to provide an arrangement that overcomes the above drawbacks. In particular, the invention proposes a simple, reliable, and economical arrangement that helps to keep an opening closed in the event of an impact.

[0008] To achieve this objective, the invention relates to an arrangement for a vehicle opening, particularly for a motor vehicle, specifically a side door type opening, the arrangement comprising:

[0009] - a lock controlling the opening of such an opening,

[0010] - a lock actuating lever pivoting in a first direction towards a rest position of the actuating lever in which the lock blocks such an opening, and in a second direction towards an opening position of the actuating lever in which the lock releases such an opening,

[0011] - an opening control for such an opening, comprising a fixed part, in particular an external opening control,

[0012] - a means of transmitting motion between the actuating lever and the lock, in particular a cable-type means of transmitting motion,

[0013] - an exterior panel of such an opening,

[0014] - a means for locking the pivoting of the actuating lever in the second direction so that, in the event of an impact on the outer panel, the actuating lever is held in or at the rest position, the locking means comprising a first part and a second part, the first part being designed to slide relative to the second part during such an impact, in particular the first part being designed to slide within the second part. The second part of the locking means may be integrated into the fixed part of the opening control, in particular the second part may be made of the same material as the fixed part of the opening control.

[0015] The first part and the second part can be fixed to each other by a first fastening means intended to allow the separation of the first part from the second part during such an impact.

[0016] The first part and the second part of the locking means may be made of the same material and may form a single piece, and the first part and the second part may be fixed to each other by a second fastening means designed to break upon such an impact.

[0017] The second fastening means may include at least one breakable fin extending between the first part and the second part.

[0018] The second part can be fixed, in particular by clipping and / or screwing, onto the fixed part of the opening control, in particular onto a base of the opening control.

[0019] The first part may include a bearing face arranged at a distance, in the transverse or substantially transverse direction, of between 3 mm and 9 mm, in particular 6 mm, from an element, in particular the lock, against which the bearing face of the first part may come into contact in the event of an impact.

[0020] The bearing face may be flat or substantially flat and / or may extend in a vertical and longitudinal plane or substantially in a vertical and longitudinal plane.

[0021] The first part may include a locking portion, in particular a beveled locking portion comprising a locking face. The actuating lever may include a stop face designed to come into contact with the locking portion of the first part upon impact, so as to prevent any pivoting of the actuating lever in the second direction.

[0022] The invention also relates to an opening, in particular an opening of a motor vehicle, in particular a side door type opening, comprising an arrangement as defined above.

[0023] The invention also relates to a vehicle, in particular a motor vehicle, comprising an opening as defined above and / or an arrangement as defined above.

[0024] The invention also relates to a method of operation of a vehicle as defined above, or of an opening as defined above, or of an arrangement as defined above, the method comprising, in the event of a lateral impact on the opening:

[0025] - a step involving pressure on the outer panel and deformation of the outer panel under the effect of the pressure,

[0026] - a step involving the movement of the opening control, in particular the movement of the fixed part of the opening control and / or a base of the opening control, along the transverse or substantially transverse direction in the same direction as the direction of the impact resulting from the deformation of the outer panel,

[0027] - a contact step of the locking means against an element, in particular a bearing face of the first part against the lock,

[0028] - a translation step of the first part relative to the second part along the transverse or substantially transverse direction in a direction opposite to the direction of the impact, in particular due to the separation of the first part relative to the second part by the detachment of a first fastening means or the breakage of a second fastening means between the first part and the second part,

[0029] - a step of blocking the pivoting of the actuating lever in the second direction, in particular by contact between a stop face of the actuating lever and a blocking face of a blocking portion of the first part.

[0030] These objects, features, and advantages of the present invention will be described in detail in the following non-limiting description of an embodiment, in conjunction with the accompanying figures, among which: Figure 1 is a view of a vehicle according to an embodiment of the invention; Figure 2 is a top view of an arrangement according to an embodiment of the invention; Figure 3 is a partial cross-sectional view along a vertical and longitudinal plane of the arrangement according to the embodiment of the invention; Figure 4 is a partial perspective view of the arrangement according to the embodiment of the invention; Figure 5 is a perspective view of a locking means for the arrangement according to an embodiment of the invention; Figure 6 is another perspective view of the locking means for the arrangement according to the embodiment of the invention;Figure 7 is a partial schematic cross-sectional view along a vertical and transverse plane of a vehicle opening according to an embodiment of the invention, the opening being closed, not subjected to an impact, and the opening control not being activated; Figure 8 is a partial schematic cross-sectional view along a vertical and transverse plane of the opening according to the embodiment of the invention, the opening being closed, not subjected to an impact, and the opening control being activated; Figure 9 is a partial schematic cross-sectional view along a vertical and transverse plane of the vehicle opening according to the embodiment of the invention, the opening being closed and subjected to an impact; Figure 10 is a partial schematic cross-sectional view along a vertical and transverse plane of the vehicle opening according to the embodiment of the invention, the opening being closed and deformed by an impact.

[0031] The direction in which a motor vehicle travels in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, we use a right-handed coordinate system XYZ in which X is the longitudinal direction in the front-to-back direction of the vehicle, therefore directed towards the rear, Y is the transverse direction directed to the right, and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the motor vehicle usually travels in the longitudinal direction and is opposite to the backward direction.

[0032] Figure 1 illustrates an embodiment of a vehicle, for example, a motor vehicle 1. The motor vehicle 1 includes at least one opening according to this embodiment. Preferably, the opening is a side door 2. Although the side door 2 shown in Figure 1 is a left-hand front side door, it could also be a right-hand front side door. The opening could also be a left- or right-hand rear side door intended for rear passengers, i.e., those positioned behind or substantially behind the driver and possibly the front passenger(s). Obviously, several rear side doors could be arranged on the same side of the motor vehicle 1. The side doors could also be hinged or sliding. Alternatively, the opening could also be a rear hinged door or a trunk lid.

[0033] In what follows, door 2, illustrated and described, is a left-hand side door. Door 2 comprises an arrangement 10, illustrated in figures 2, 3, and 4.

[0034] The arrangement 10 includes a lock 11 whose operating states enable the movement and immobilization of the door 2 on the vehicle body.

[0035] The arrangement 10 includes a door opening control 14 for the door 2, preferably an external opening control. An "external opening control" is understood to mean a control arranged at least partially outside the vehicle. Such an external opening control is intended to be operated from outside the vehicle, in other words, used to open the door 2 in order to access or enter a passenger compartment of the vehicle. For example, the external opening control 14 includes a movable part 14' such as a handle or other grasping means, intended to be pulled outwards from the vehicle, as illustrated by arrow T in Figures 2 and 8. The opening control 14 includes a fixed part 15. The opening control 14 also includes an actuating lever 12.

[0036] The actuating lever 12 is able to pivot, around a pivot axis A, in a first direction S1 towards a rest position PR of the actuating lever 12 in which the opening command 14 does not cause the door 2 to open, as illustrated in figure 7. The pivoting of the actuating lever 12 is also able to pivot in a second direction S2, opposite to the first direction S1, towards an opening position PO of the actuating lever 12 in which the COE 14 requests the lock 11 to release the opening of the door 2 (figure 8).

[0037] The arrangement 10 further includes a means 13 for transmitting motion between the actuating lever 12 of the opening control 14 and the lock 11. Advantageously, the transmission means 13 is a cable 17, for example equipped with a sheath and / or sheath stop(s) so as to allow control of the stroke of the cable 17. According to an alternative embodiment not shown, said transmission means may be a rod made from a rigid metal wire.

[0038] Thus, as illustrated in Figure 8, the pull T on the moving part 14' of the opening control 14 causes a winding E and / or a displacement of one end 17' of the cable 17 attached to the actuating lever 12. The winding E and / or displacement of the end 17' results in the release of the lock 11 by displacement of the other end of the cable at the lock 11 (not shown). The winding E and / or displacement of the end 17' occurs, for example, downwards. The displacement of the other end of the cable at the lock then occurs, for example, upwards. In any case, the displacement of the cable end at the lock releases the lock and opens the door 2, or allows the door 2 to be opened without resistance.

[0039] The arrangement 10 also includes an outer panel 3 of the door 2. The outer panel 3 is, for example, made of sheet steel and / or aluminum. Thus, the outer panel 3 deforms preferentially in the event of an impact F, particularly a lateral impact, in order to absorb as much energy as possible. Indeed, as illustrated in Figures 9 and 10, during an impact F at the level of the opening control 14 or substantially in the area of ​​the opening control 14, the outer panel 3 moves closer to an inner panel 4 of the door 2.

[0040] Advantageously, the opening control 14, in particular its fixed part 15, is fixed at least partially on the outer panel 3.

[0041] The arrangement 10 further includes a locking means 20 to prevent the pivoting of the actuating lever 12 in the second direction S2. More specifically, this locking means 20 only acts in the event of an impact F on the outer panel 3. Thus, in the event of such an impact F, the actuating lever 12 is held towards, or at, the rest position PR as will be detailed later.

[0042] As illustrated in Figures 5 and 6, the locking means 20 comprises a first part 21 and a second part 22. The first part 21 is designed to slide relative to the second part 22 during an impact in the Y direction. For example, the first and second parts have complementary shapes to ensure a sliding connection between them. Preferably, the first part 21 is designed to slide within the second part 22. Advantageously, as illustrated in Figures 3 to 6, the first part 21 can be at least partially perforated, for example by openings 21' of any type of cross-section, for example straight, square, rectangular, or triangular, extending along the translational direction of the first part 21. In another embodiment not shown, the first and second parts have complementary shapes to ensure a pivoting connection between them.Preferably, the first part 21 is intended to pivot around the second part 22.

[0043] As illustrated in figures 7 and 8, the first part 21 and the second part 22 are fixed to each other by a second fixing means 23 according to the preferred embodiment, or by a first fixing means according to a variant not illustrated.

[0044] According to one embodiment, the first part 21 could also be separate from the second part 22 so that their assembly could be carried out during the assembly of the parts in the door by an operator who would fix it for example by harpooning or gluing.

[0045] In the preferred embodiment, the first part 21 and the second part 22 of the locking means 20 are formed from a single piece of material. In other words, the first part 21 and the second part 22 are a single piece produced from the same tooling mold, for example, by a molding process. For example, the material of the locking means is polypropylene. In this case, the second fastening means 23 is advantageously designed to break upon impact F. Preferably, the second fastening means 23 then comprises at least one fin 27 extending between the first part 21 and the second part 22. For example, two fins 27 are arranged, one at the top and the other at the bottom, or one on one side and the other on the opposite side. Alternatively, more fins 27 are planned, for example two at the top and two at the bottom, or two on one side and two on the other side.Preferably, the fins have similar or even identical cross-sectional areas so as to promote their simultaneous breaking and / or under the same or substantially the same compressive force which will be described later.

[0046] The second part 22 is fixed to the fixed part 15 of the opening control 14. For example, the second part 22 is fixed by clipping and / or screwing. At least one clipping area is therefore preferably provided on the fixed part 15 of the opening control 14 to facilitate the fixing of the second part 22. For this purpose, the second part 22 includes at least one lug 28 or rib, for example in the shape of or substantially in the shape of a sphere or hemisphere, intended to cooperate with at least one cavity of complementary shape provided in the fixed part 15. Preferably, as illustrated in Figures 5 and 6, two lugs 28 are provided. The second part 22 may also include, for example, at least one hole 29 for the passage of at least one screw intended to screw into the fixed part 15 or to cooperate with tapped and / or attached elements on the fixed part 15, for example nuts.Preferably, as illustrated in Figures 5 and 6, two holes 29 are provided. Thus, the locking means 20, more precisely its second part 22, can be assembled onto the opening control 14 by inserting the lugs 28 into cavities in the opening control. This insertion is advantageously followed by tightening screw(s) through the hole(s) 29.

[0047] Preferably, the fixed part 15 of the opening control 14 is a base 16 extending for example into a lower part of the opening control 14 as illustrated in Figure 4 and schematically illustrated in Figure 7.

[0048] According to an unillustrated variant of the preferred embodiment, the second part of the locking means is integrated into the fixed part of the opening mechanism. For example, the second part is formed from the same material as the fixed part of the opening mechanism. In this case, the first and second parts are fastened to each other by a first fastening means. The first fastening means is capable of releasing, i.e., separating, the first part from the second part upon impact F. The first fastening means comprises, for example, one or more clips or tabs formed on the fixed part of the opening mechanism that cooperate with one or more cavities, grooves, or notches formed on the first part.Alternatively, the first fastening means comprises, for example, one or more clips or tabs formed on the first part cooperating with one or more cavities, grooves, or notches formed on the fixed part of the opening control. Alternatively again, the first fastening means comprises, for example, several clips or tabs formed on the first part and on the fixed part of the opening control cooperating with one or more cavities, grooves, or notches formed on the fixed part of the opening control and on the first part.

[0049] The first part 21 preferably includes a bearing face 24. As illustrated in Figures 7 and 8, outside of an impact situation, the bearing face 24 is arranged at a distance D, in the transverse or substantially transverse direction, of between 3 mm and 9 mm, in particular 6 mm, from an element 5. The element 5 is arranged between the bearing face 24 and the inner panel 4. Preferably, this element 5 is, or includes, the lock 11. The bearing face 24 comes against, i.e., into contact with, the element 5 in the event of an impact F. This is caused by the outer panel 3 moving towards the inner panel 4 during an impact, as illustrated in Figures 9 and 10.

[0050] In an alternative embodiment not shown, the bearing face 24 of the first part 21 is positioned directly opposite the inner panel 4. For this purpose, to ensure rigidity of the inner panel 4 against deformation, a spacer (not shown) can be added between the face 24 and the inner panel 4.

[0051] Preferably, the bearing face 24 is flat, or substantially flat. The bearing face 24 extends, for example, in a vertical and longitudinal plane, or substantially in a vertical and longitudinal plane.

[0052] The first part 21 includes a locking portion 25. For example, the locking portion 25 replicates the geometry of the stop face 18 of the lever 12 and could therefore be beveled. For example, the locking portion 25 includes a locking face 26, as illustrated in particular in Figures 5 and 7.

[0053] The actuating lever 12 includes a stop face 18. The stop face 18 is intended to come into contact, or substantially into contact, with the blocking portion 25 during the impact F. The blocking portion 25 then blocks any pivoting of the actuating lever 12 in the second direction S2 during an impact as will be explained below.

[0054] An embodiment of a method for operating a vehicle, opening, or arrangement in the event of a side impact F according to the invention is described below. Thus, in the event of a side impact F on the door 2, the method comprises a step of applying pressure to the outer panel 3 and deforming the outer panel 3 under the effect of this pressure.

[0055] Simultaneously, or substantially simultaneously, with the support step, the method includes a step of moving the opening control 14 along the transverse direction Y, or substantially transversely, in the same direction as that of the impact F. In other words, this movement is towards the inner panel 4. This movement step is linked to the deformation of the outer panel 3 towards the inner panel 4. This movement step causes the fixed part 15 of the opening control 14 and / or its base 16 to move towards the inner panel 4.

[0056] Following the displacement step, the process then includes a contact step of the locking means 20 against the element 5. The distance D is thus completely "made up" due to the displacement of the outer panel, which in turn causes the external opening control 14 fixed to the outer panel to move. As mentioned previously, the element 5 is preferably the lock 11. Thus, the contact in the contact step occurs between the bearing face 24 of the first part 21 and a surface 11' of the lock 11, as illustrated in Figure 9.

[0057] Following the contact step, the process includes a translation step of the first part 21 relative to the second part 22. This translation preferably occurs in the transverse, or substantially transverse, direction. The translation takes place in the direction opposite to the direction of the impact F, with the first part 21 abutting the lock 11 in the direction of the impact. This translation is preferably made possible by the break in the fins 27 extending between the first part 21 and the second part 22, as illustrated in Figure 9. In other words, the subsequent compression of the outer panel separates the first part 21 from the second part 22. The first part 21 then slides within the second part 22.

[0058] According to the variant mentioned above, the translation step of the first part is preferably achieved by "unclipping." Indeed, in this variant, the first part is linked to the fixed part of the opening control by a first detachable means, for example without breakage.

[0059] Following the translation step, the process includes a step to prevent the pivoting of the actuating lever 12. For example, as soon as a translation of approximately 1 mm is achieved, the first part 21 begins to interfere with the actuating lever. Further translational travel strengthens the locking action. The actuating lever 12 is prevented from pivoting in the second direction S2. This locking is ensured by the contact, or near contact, between the stopping face 18 of the actuating lever 12 and the locking face 26 of the locking portion 25 of the first part 21, as illustrated in Figure 10. Clearly, the translational travel of the first part 21 within the base 16 of the opening control 14 is defined to prevent the lever 12 from reaching its open position PO, as illustrated in Figure 8.The forced return of the actuating lever to its rest position PR prevents any unintended movement within the lock, thus helping to keep the lock closed. This forced return of the actuating lever to its first pivot position S1 is facilitated by the beveled shape of the blocking portion 25, which cooperates with the stop face 18. As illustrated in Figure 8, preferably, an edge 26' of the blocking portion 25, for example at the bottom of the blocking face 26, first comes into contact with the stop face 18 at an end 18' of the stop face 18 furthest from the pivot axis A of the lever. The first part 21 then exerts a significant force against the stop face 18 to block or counteract the pivoting. Indeed, given the distance between the pivot axis A and the point of contact between the edge 26' and the end 18', the pivot lever arm in the first direction S1 is particularly important.Furthermore, in the event of pivoting in the first direction S1 caused by translation of the first part 21, the beveled shape limits friction. Finally, the beveled shape is preferably defined so that the locking face 26 and the stopping face 18 are parallel or substantially parallel at the end of the impact, as illustrated in Figure 10.

[0060] Thus, despite the inertia during a shock which tends to rotate the lever 12 around its axis A in the second direction S2, the arrangement 10 makes it possible to counter this effect and avoid this rotation which would cause the opening of the door 2.

[0061] In summary, we are dealing with a lever blocker for the actuating lever 12, also called a counterbalancer. The actuating lever 12 incorporates an inertial mass to limit the risk of opening due to inertial forces. The counterbalance or deflection function is integrated into the part 12 so that it provides the connection between the external control forming the gripping means and the moving lock interface. The blocker or blocking means 20 includes a system that can be described as a "drawer" with regard to the first part 21 sliding within the second part 22. Thus, in the event of a lateral impact on a door comprising the arrangement 10, the door does not open unintentionally.

[0062] Even if the rear door is not completely crushed during a regulatory test, the arrangement allows the rear door to remain closed. Furthermore, regulations require that the kinematic linkage between the opening mechanism and the lock be continuous during the test, which is the case with arrangement 10. The motor vehicle 1, equipped with doors each incorporating arrangement 10, is therefore type-approved and compliant with regulations. It should be noted that arrangement 10 is particularly well-suited to a rear door opening mechanism 14, which is generally connected to its lock by cable.

[0063] In other words, the arrangement 10 prevents the self-opening of the external opening control 14 during a lateral impact by taking advantage of the deformation of the outer panel 3 of the door 2. Indeed, the deformation of the outer panel 3 locks the actuating lever 12 in its rest position PR. Since the actuating lever 12 is responsible for pulling the cable 17 that transmits the opening command to the lock, the cable is not pulled. Lacking an opening command, the lock remains closed, leaving the door closed. More precisely, the prevention of the actuating lever's pivoting is ensured by the crushing of the locking means 20, which is "sandwiched" between the lock 11 and the opening control 14. Due to the reduction in the distance along the transverse direction Y between the outer panel 3 and the inner panel 4 during an impact, the locking means 20 is crushed.The first part 21 enters the second part 22, like a drawer, when the outer panel 3 is compressed. The locking portion 25, preferably beveled, therefore uses the crushing of the door to fit against the actuation lever 12 and lock it in pivoting in the second direction S2.

[0064] Preferably, the locking means 20 is positioned on the rear face of the external opening control, that is, opposite the lock 11. As mentioned previously, the locking means 20, according to the preferred embodiment, is attached, for example, by clipping and / or screwing onto the base 16 of the opening control 14. The parts 21 and 22 are, for example, joined by a recessed connection provided by the breakable fins 27. The two parts 21 and 22 are thus linked by areas of weakness that break during the shock or impact. It should be noted that there is no relative movement between the first part 21, the drawer, and the second part 22, the support, before compression due to the shock. Advantageously, the respective shapes of the parts 21 and 22 ensure sufficiently long guidance to prevent sagging.Non-functional peripheral games between the first and second parts 21, 22 are increased in order to avoid any risk of shoring.

[0065] To optimize efficiency, the bearing face 24 of the first part 21 is positioned close to the element 5, along the transverse direction, against which it is designed to bear during an impact. As previously mentioned, it is preferable for the element 5 to be the lock 11. However, to ensure that no unwanted contact occurs, the distance or clearance D is, for example, 6 mm between the bearing face 24 and the surface 1T of the lock 11. Similarly, the volume within the second part 22, under non-impact conditions and along the transverse direction, is such that the locking portion 25 is in the immediate vicinity of the actuating lever 12 without interfering with its pivoting stroke, as illustrated in Figure 8. For example, the locking means 20, when not subjected to an impact, allows a cable stroke 17 that always exceeds the opening stroke of the lock without interfering with the actuating lever 12.For example, the blocking portion 25 of the first part 21 is at a distance D1 of approximately 1 mm from the actuating lever 12 at the end of the opening stroke, as illustrated in Figure 8.

[0066] In cases where the locking device 20 is attached to the opening mechanism 14, the solution requires little or no modification to the opening mechanism. The opening mechanism can then remain a standard component usable on various doors, whether or not they include the arrangement 10. Furthermore, the solution is compatible with different doors regardless of the arrangement of the components within the door, provided that the impact face 24 of the first part 21 is correctly positioned to perform its function. Depending on the embodiment, the second part is integrated into the fixed part of the opening mechanism or directly into its base. In this case, the first part or drawer is, for example, clipped into the opening mechanism in the non-impact position.During compression due to an impact, the breakage of the clips through intentional fragility or "unclipping" replaces the breakage of the fins as described in the preferred embodiment previously outlined. For example, depending on the variant, the second part integrated into the fixed part of the opening control is standard across several door configurations, while only the first part is adapted. It should be noted that once the first part is released, it must always be guided in translation by the second part towards the lever to immobilize it.

[0067] The solution is applicable to any front or rear side door, regardless of the vehicle range, including commercial vehicles, particularly when the lock and opening mechanism are connected by a cable. It is particularly reliable.

[0068] It should be noted that, in addition to saving the material needed to produce the first part 21, without reducing rigidity in the compression direction, the openings 21' allow for a reduction in mass without compromising the incompressibility of the first part. Mounting the locking device in each door therefore results in a negligible increase in mass. This makes this solution compatible with the environmental objectives of reducing vehicle mass in connection with reducing pollutant emissions. Since the locking device, particularly the second part, is fixed to or integrated into the opening mechanism, it is easy to maintain precise geometric conditions relative to the element against which the first part abuts during an impact. This solution is applicable in many cases, even if the door frame lacks a lock directly opposite or substantially opposite it in the transverse direction of the first part.Indeed, there is always an element on which the first part can come up against, for example the interior panel 4.

[0069] In observation, the solution according to the invention therefore achieves the desired objective of preventing the unintentional opening of door 2 when this door 2 undergoes a lateral impact F deforming the outer panel 3 towards the interior of the vehicle and offers the following advantages:

[0070] - it can adapt to any interior door shape by adapting the shape of the first part;

[0071] - it can be used on different types of motor vehicles, including trucks, vans, light or industrial vehicles, or even public transport vehicles;

[0072] - it improves the safety of the vehicle equipped with this solution, the passenger(s) being protected by the door remaining closed, even in the event of successive impacts on the door, for example during a pile-up and / or during a secondary accident.

[0073] The invention is particularly well suited to a motor vehicle equipped with a side door comprising an external opening control connected to a lock by a cable-type drive system. It relates to an arrangement within such a door. It also relates to a door comprising such an arrangement. Finally, it relates to a vehicle comprising such a door and / or such an arrangement. It further relates to a method for operating such a door.

[0074] Finally, although the solution was described for a side door subjected to a primarily lateral F-impact, it could also be suitable for a rear front door in the event of a rear-end collision. Indeed, a van and / or utility vehicle with at least one rear door equipped with an external opening mechanism, for example, an external handle connected to a lock by a cable-operated system, can benefit from the advantages of this solution in the event of a rear-end collision.

[0075] Optionally, the solution can be adapted to a transmission of movement between the opening control and the rod-type lock.
