[0002] Safety device for a vehicle, vehicle

[0003] The invention relates to a safety device for a vehicle, in particular a motor vehicle, having a door which is displaceably arranged on a body of the vehicle, in particular for releasing and closing a door opening of the body, having a crash bolt projecting from a holding section laterally from the body in the direction of the door and having a recess arranged on the door and designed to partially accommodate the crash bolt.

[0004] Furthermore, the invention relates to a vehicle with the safety device described above.

[0005] Safety devices of the type mentioned above are already known from the prior art. For example, the published patent application KR 20070084667 A discloses a safety device for a motor vehicle in which a crash bolt is provided on the body side, which interacts with a recess on the door side to prevent the door from being pushed into the vehicle interior in the event of a side impact or a side crash. By engaging the crash bolt in the recess, the door is additionally held back against the body and prevented from penetrating the vehicle interior. The recess is formed in a reinforcing plate of the vehicle door, so that the crash bolt interacts with the reinforcing element in the event of a crash.

[0006] The invention is based on the object of creating an improved safety device which in particular offers increased stability and in particular brings comfort advantages for a user of the vehicle.

[0007] The object underlying the invention is achieved by a safety device having the features of claim 1. It is characterized in that the crash bolt is fastened to the body and a crash element extending at least substantially over the entire length of the door is arranged on the door and is designed to be supported on the holding section of the body with a first end, which has the recess, in the event of a side crash. The safety device according to the invention has the advantage that the crash bolt interacts with a crash element that extends at least substantially over the entire length of the door, so that high forces can be advantageously transmitted and dissipated without the door deforming into the vehicle interior.Because the crash bolt is arranged or attached directly to the body, the crash bolt is also held particularly securely to the motor vehicle and transmits the accident forces directly into the vehicle body. Because the crash element extends at least substantially over the entire length of the door, i.e. over the entire length or almost the entire length of the door, the crash element extends from one door edge to an opposite or adjacent door edge, thereby providing the door with a high level of stability. The door is preferably pivotable on the body, in particular about a vertical or horizontal axis, and / or displaceably mounted.

[0008] Furthermore, it is preferably provided that a trim panel is arranged on the body, which conceals the crash bolt and can be penetrated by the crash bolt in the event of a side impact, allowing the crash bolt to enter the receptacle. The trim panel thus normally conceals the crash bolt, which offers visual advantages on the one hand and also protects the user from getting caught on the crash bolt, for example, when getting in while wearing a piece of clothing, such as a coat or the like, and damaging the piece of clothing during the process or when subsequently closing the door.

[0009] Furthermore, it is preferably provided that, in addition or alternatively, an interior trim panel is arranged on the door. This panel conceals the crash element and can be penetrated by the crash bolt in the event of a side impact, allowing the crash bolt to enter the recess. Thus, the recess is initially invisible and, for example, protected from external influences. The interior trim prevents, for example, small parts or dirt from entering the recess, which could subsequently reduce the effectiveness of the crash bolt engaging the recess. This also protects the door from water retention and corrosion.

[0010] According to a preferred embodiment of the invention, the trim part runs at least substantially parallel to the interior trim part of the door, at least in the retaining section. This ensures that the door fits tightly against the body of the motor vehicle in the region of the retaining section.

[0011] Furthermore, it is preferably provided that the crash bolt has a cutting tip facing the door for cutting the trim element and / or the interior trim part in the event of a side impact. The cutting tip is characterized in particular by a cutting edge or blade formed at the free end of the crash bolt. In particular, the cutting tip is formed integrally with the crash bolt or is integrated into the crash bolt. For this purpose, the crash bolt has a wedge shape, for example, at its free end.

[0012] Preferably, the crash bolt is positioned on or near a vehicle pillar. This ensures that high forces can be transferred to the vehicle body in the event of a side impact.

[0013] In particular, the door is pivotally mounted on a first vehicle pillar of the body, and the crash bolt is arranged on a second vehicle pillar of the vehicle. As a result, the crash bolt is positioned away from the pivot bearing of the door on the body, allowing side impact forces to be safely absorbed by both the pivot bearing and the crash bolt. In particular, the second vehicle pillar is a vehicle pillar adjacent to the first vehicle pillar.

[0014] Furthermore, it is preferably provided that the crash bolt is located in the transition between the vehicle pillar and a longitudinal member of the body. As a result, the crash bolt is located in a highly resilient area of ​​the body, so that high forces can be absorbed in the event of a side impact without the door being pushed into the vehicle interior. Even in an embodiment in which the door is not pivotable on the first vehicle pillar and the crash bolt is arranged on the second vehicle pillar, but in which the vehicle door is slidably mounted, for example, on the body, in particular on a longitudinal member between adjacent vehicle pillars of the body, the crash bolt is preferably arranged in the transition from one of the vehicle pillars to the longitudinal member of the body.

[0015] Preferably, the crash element is aligned at an angle to the longitudinal member. Due to the inclined alignment, the crash element extends, in particular, from the transition area of ​​the vehicle pillar to the longitudinal member to an opposite section of the door, which is located, in particular, above the longitudinal member, for example, at the mid-height of the door or between hinges by which the door is pivotally mounted on the body. This ensures advantageous force transmission and protective effect.

[0016] The vehicle according to the invention with the features of claim 10 is characterized by the safety device according to the invention. This results in the advantages already mentioned. Further advantages and preferred features and combinations of features emerge in particular from the above description and from the claims. The invention will be explained in more detail below with reference to the drawing. These drawings show:

[0017] Figure 1 shows a motor vehicle in a simplified side view,

[0018] Figure 2 shows a first detailed view of the motor vehicle,

[0019] Figure 3 shows a second detailed view of the motor vehicle, and

[0020] Figures 4A and 4B show a sectional view of the motor vehicle in the area of ​​an advantageous safety device in different operating states.

[0021] Figure 1 shows a simplified side view of an advantageous motor vehicle 1, of which essentially only a body 2 is shown here. The body 2 has two frame-shaped door openings 3, 4, to which a door 5 or 6 can be assigned or is assigned, respectively. In Figure 1, the doors 5, 6 are shown essentially transparent in order to be able to illustrate the advantageous embodiment. The door 5 is pivotally mounted on a first vehicle pillar 7, in particular the A-pillar, by one or more pivot joints 8. The door 6 is pivotally mounted on a second vehicle pillar 9, in particular the B-pillar, by one or more pivot joints 10. In the closed position of the door 5, it also rests against the second vehicle pillar 9, and in the closed position the door 6 rests against a third vehicle pillar 11, in particular the C-pillar, of the motor vehicle 1 in order to close the respective door opening.

[0022] Both doors 5, 6 each have a crash element 12, 13. The crash elements 12, 13 are each designed as crash tubes or crash struts, each extending at least substantially over the entire length of the respective door 5, 6. In the closed position of the door, a first end 14 of the crash element 13 is assigned to the transition from the vehicle pillar 11 to a longitudinal member 15 of the body 2. The crash element 13 thus ends in the kink or corner where the vehicle pillar 11 and the longitudinal member 15 meet. The same applies to the crash element 12, which ends in the transition from the vehicle pillar 9 to the longitudinal member 15.The crash elements 13, 12 are in particular each aligned inclined to the longitudinal member 15 such that they end with the respective first end 14 in the transition of the respective vehicle pillar 10, 11 to the longitudinal member 15, in order to end with the second end approximately halfway up the door on the respective opposite vehicle pillar 7, 9. As a result, the respective second end of the respective crash element 12, 13 is, for example, at the level of or adjacent to one of the pivot joints 8, 10, or between the pivot joints 8, 10.

[0023] The crash elements 12, 13 are each part of a safety device 16, 17 of the motor vehicle 1. Because the safety devices 16, 17 are basically designed the same, the design of both safety devices 16, 17 is explained in more detail below with reference to the safety device 17.

[0024] Figure 2 shows a detailed view of the body 2 of the motor vehicle 1 in a detailed view of the safety device 17. The vehicle pillar 11 and the longitudinal member 15 are shown. In the transition region, a holding section 18 of the body 2 is formed, which, when the door 4 is closed, lies opposite the first end 14 of the crash element 13. A crash bolt 19 is arranged in the holding section 18. The crash bolt 19 is fastened to the body 2 either directly or with the aid of a reinforcing element 20. The crash bolt 19 protrudes laterally, in particular horizontally, from the body at the holding section 18 in the direction of the door 6, in particular in the direction of the end 14 of the crash element 13, as shown, for example, in Figure 4A, so that its free end 21 faces the door 4. The free end 21 is thus spaced from the body 2 and protrudes from the holding section 18.

[0025] Figure 3 shows the same detailed view of Figure 2, with the difference that the body 2 is now provided with a trim part 22. The trim part 22, in particular the trim panel, covers the body 2 and the crash bolt 19, so that the crash bolt 19 is hidden behind the trim part 22 and thus not visible from the outside.

[0026] Figures 4A and 4B show a sectional view along line AA of Figure 1 through the area of ​​the safety device 17 in which the crash bolt 19 is located. In Figure 4A, in addition to the body 2, the trim element 22 is also shown, which conceals the crash bolt 19. For this purpose, the trim element 22 extends at a distance from the retaining section 18, at least in the area of ​​the crash bolt 19, so that the free end 21 of the crash bolt 19 is spaced from the trim part 22.

[0027] At its end 14 opposite the crash bolt 19, the crash element 13 has a recess 23 which, according to the present exemplary embodiment, is designed as an opening or through-hole in the crash element 13. The recess 23 has an inner contour that is slightly larger than the outer contour of the crash bolt 19. In the closed position of the door 4, the recess 23 lies opposite the free end 21 of the crash bolt 19. The door 6 has an interior trim part 24 that covers and conceals the crash element 13 on the inside of the door. The interior trim part 24 thus also extends over the recess 23 so that it is not visible from the outside. The interior trim part 24 runs parallel to the trim element 22 in the region of the holding section 18 so that the door 6 can be arranged particularly close to the body 2 in the closed position.In the closed position, a gap preferably remains between the interior trim part 24 and the trim part 22, as shown in Figure 4A.

[0028] In the event of a side crash or a side impact in the area of ​​the door 6, the following function of the safety device 17 results, as shown in particular by means of Figure 4B.

[0029] Figure 4B shows, by way of example, the safety device 17 in the activated or deformed state after a side impact. The side impact impinges on the door 6 in the direction of the interior of the motor vehicle 1, causing the door 6 to deform. In particular, the crash element 13 is forced into the vehicle interior, causing the free end 14 to be displaced toward the crash bolt 19. If the force generated by the side impact is sufficiently large, the crash element 13 is displaced and pressed against the retaining section 18 in such a way that the crash bolt 19 cuts through the trim part 22 and the interior trim part 24 and is pushed into the recess 23 of the crash element 13. For this purpose, the crash bolt 19 preferably has a cutting edge 25 at its free end 21, which is designed to cut the trim part 22 and the trim part 24 in the event of such an impact or side crash.By engaging the crash bolt 19 in the recess 23, a positive connection is now established between the crash element 13 or the door 6 and the crash bolt 19 or the body 2, by means of which the door 6 is locked to the crash bolt 19 at the end remote from the pivot joint 10 and is prevented from being pressed into the vehicle interior.

[0030] The safety device 17 thus ensures that in the event of a side impact, the door 6 cannot be moved into the vehicle interior. This advantageously reduces the risk of injury to vehicle occupants. The hidden arrangement of the fastening bolt and also the recess 23 ensures that the safety device 17 is not visually noticeable, and that people cannot injure themselves on the fastening bolt or damage their clothing when getting in or out. While the present exemplary embodiment relates to a door 6 that can only be pivoted, according to a further exemplary embodiment (not shown here), the door is slidably mounted on the body 2 of the vehicle, in particular on the longitudinal member 15.At least one crash bolt 19 is then preferably arranged in the transition area or in the transition between one of the vehicle pillars 7, 9, 11 and the longitudinal member 15.
