Abstract
Description
Technical Field
[0001] The present invention relates to a safety device for a vehicle, particularly a motor vehicle, comprising: a door, which is displaceably arranged at the vehicle body, particularly a door opening for releasing and closing the vehicle body; a crashbolzen (sometimes also called a crash bolt) projecting laterally from the vehicle body in the direction of the door at a holding section; and a recess arranged at the door and configured to partially accommodate the crashbolzen.
[0002] Furthermore, the present invention relates to a vehicle having the aforementioned safety equipment. Background Technology
[0003] Safety devices of the above type are already known from the prior art. For example, publication KR 20070084667 A discloses a safety device for a motor vehicle, wherein a collision pin is present on the vehicle body side, which interacts with a recess on the door side to prevent the door from being forced into the vehicle's interior space in a side impact or lateral collision. By engaging the collision pin in the recess, the door is additionally blocked at the vehicle body and intrusion into the vehicle's interior space is prevented. The recess is here constructed in the reinforcing plate of the vehicle door, so that in the event of a collision, the collision pin interacts with the reinforcing element. Summary of the Invention
[0004] The present invention is based on the objective of creating an improved safety device that provides, in particular, enhanced stability and, more importantly, increased comfort for vehicle users.
[0005] The objective of this invention is achieved by a safety device featuring the characteristics of this invention. It is characterized by a collision pin fixed to the vehicle body and a collision element arranged at the door, extending at least substantially the entire length of the door, the collision element being configured to be supported at a retaining section of the vehicle body with a first end having a recess in a side impact. The safety device according to the invention has the advantage that the collision pin interacts with the collision element, which extends at least substantially the entire length of the door, thereby advantageously transmitting and reducing large forces without deforming the door into the vehicle's interior space. Since the collision pin is directly arranged at or fixed to the vehicle body, it is also particularly reliably held at the vehicle body and directly transmits the accident force into the vehicle body. Because the collision element extends at least substantially the entire length of the door (i.e., the entire or almost the entire length of the door), it extends from the door edge to the opposite or adjacent door edge, thereby introducing higher stability into the door. Preferably, the door is pivotally, particularly about a vertical or horizontal axis, and / or movably supported at the vehicle body.
[0006] Furthermore, it is preferably configured such that a liner is provided at the vehicle body, which covers the collision pin and is permeable by the collision pin in a side collision, allowing the collision pin to reach the receiving portion. Thus, by means of the liner, the collision pin is normally covered, which provides a visual advantage and also protects the user from, for example, clothing parts (such as coats) getting caught on the collision pin when getting into the vehicle, and from being damaged thereon or by subsequently closing the door.
[0007] Furthermore, preferably, additionally or alternatively, an internal baffle is provided at the door, which covers the impact element and is permeable by the impact pin in the event of a side impact, allowing the impact pin to reach the receiving portion. Thus, the recess is initially invisible and, for example, protected against external influences. In this way, the internal baffle, for example, prevents small parts or dirt from reaching the recess, which could subsequently weaken the function of the impact pin engaged in the recess. This also protects the door from water accumulation and corrosion.
[0008] According to a preferred embodiment of the invention, the retaining member extends substantially parallel to the inner retaining member of the door, at least in the retaining section. This ensures that the door fits snugly against the vehicle body in the area of the retaining section.
[0009] Furthermore, the collision pin is preferably configured such that it has a cutting tip facing the door for cutting the retaining members and / or internal retaining members during a side impact. The cutting tip is characterized in particular by a cutting edge or cutting blade constructed at the free end of the collision pin. Specifically, the cutting tip is constructed as a single piece or integrated into the collision pin. For this purpose, the collision pin may, for example, have a wedge shape at its free end.
[0010] Preferably, the collision pin is located at or near the vehicle pillar. This ensures that a larger force can be transferred to the vehicle body during a side impact.
[0011] In particular, the door is pivotally supported at the first vehicle pillar of the vehicle body, and the collision pin is arranged at the second vehicle pillar. Thus, the collision pin is located away from the pivot support of the door at the vehicle body, allowing side impact forces to be reliably absorbed both through the pivot support and through the collision pin. Specifically, the second vehicle pillar is adjacent to the first vehicle pillar.
[0012] Furthermore, it is preferably configured such that the collision pin is located in the transition between the vehicle pillar and the longitudinal beam of the vehicle body. Thus, the collision pin is located in a high-load-bearing area of the vehicle body, thereby absorbing greater force in a side impact without pressing the door into the vehicle's interior space. Similarly, in the following embodiment, where the door is not pivotable at the first vehicle pillar and the collision pin is arranged at the second vehicle pillar, and the vehicle door is movably supported, for example, at the vehicle body, particularly at the longitudinal beam between adjacent vehicle pillars, the collision pin is preferably arranged in the transition between one of the vehicle pillars and the longitudinal beam of the vehicle body.
[0013] Preferably, the collision element is inclined relative to the longitudinal beam orientation. This inclined orientation extends the collision element, particularly from the transition area from the vehicle pillar to the longitudinal beam, to the opposite section of the door, which is located above the longitudinal beam, for example, at the midpoint of the door's height or between the hinges, by which the door is pivotally supported at the vehicle body. This ensures advantageous force delivery and protective effects.
[0014] A vehicle according to the invention, possessing the features of the invention, is characterized by a safety device according to the invention. This yields the advantages already mentioned above. Attached Figure Description
[0015] Further advantages, preferred features, and combinations of features are particularly evident from the above description. The invention will now be explained in more detail with reference to the accompanying drawings. Wherein:
[0016] Figure 1 The motor vehicle is shown in a simplified side view.
[0017] Figure 2 A first detailed view of the motor vehicle is shown.
[0018] Figure 3 A second detailed view of the motor vehicle is shown, and
[0019] Figure 4A and Figure 4B Cross-sectional views of a motor vehicle in the area of advantageous safety equipment are shown under different operating conditions. Detailed Implementation
[0020] Figure 1 A simplified side view shows an advantageous motor vehicle 1, in which essentially only the body 2 is shown. The body 2 has two frame-shaped door openings 3 and 4, which are respectively fitted with or fitted with doors 5 or 6. Figure 1In the diagram, doors 5 and 6 are shown substantially transparently to allow for the presentation of advantageous construction. Door 5 is pivotally supported at the first vehicle pillar 7, particularly the A-pillar, via one or more pivot hinges 8. Door 6 is pivotally supported at the second vehicle pillar 9, particularly the B-pillar, via one or more pivot hinges 10. In the closed position, door 5 rests against the second vehicle pillar 9, and door 6 rests against the third vehicle pillar 11, particularly the C-pillar, of the vehicle 1 to close the respective door openings.
[0021] The two doors 5 and 6 each have collision elements 12 and 13. Collision elements 12 and 13 are respectively constructed as collision tubes or collision rods, extending at least substantially along the entire length of the respective doors 5 and 6. Here, the first end 14 of collision element 13 engages with the transition between the vehicle pillar 11 and the longitudinal beam 15 of the body 2 in the closed position of the door. Collision element 13 thus terminates at the bend or corner where the vehicle pillar 11 and the longitudinal beam 15 meet. Correspondingly, collision element 12 terminates in the transition between the vehicle pillar 9 and the longitudinal beam 15. Collision elements 13 and 12 are specifically inclined relative to the longitudinal beam 15 such that they terminate with their respective first ends 14 in the transition between the respective vehicle pillars 10 and 11 and the longitudinal beam 15, so that their second ends terminate at approximately half the height of the door at the respective opposing vehicle pillars 7 and 9. Thus, the corresponding second ends of the corresponding collision elements 12, 13 are located at or adjacent to one of the pivot hinges 8, 10, or between the pivot hinges 8, 10.
[0022] Collision elements 12 and 13 are respectively part of safety devices 16 and 17 of motor vehicle 1. Since safety devices 16 and 17 are constructed in a substantially identical manner, the construction of the two safety devices 16 and 17 will be explained in more detail below with reference to safety device 17.
[0023] Figure 2 A detailed view of the vehicle body 2 of the motor vehicle 1 is shown, with reference to safety device 17. The vehicle pillars 11 and longitudinal beams 15 are shown. A retaining section 18 of the vehicle body 2 is constructed in the transition area, which is positioned opposite the first end 14 of the collision element 13 when the door 4 is closed. A collision pin 19 is arranged in the retaining section 18. The collision pin 19 is fixed to the vehicle body 2 directly or by means of a reinforcing element 20. For example... Figure 4A As shown, the collision pin 19 protrudes laterally, particularly horizontally, from the vehicle body in the direction of the door 6, especially in the direction of the end 14 of the collision element 13, at the retaining section 18, such that the collision pin faces the door 4 with its free end 21. Therefore, the free end 21 is spaced apart from the vehicle body 2 and protrudes from the retaining section 18.
[0024] Figure 3 It shows the relationship with Figure 2The same detailed view is shown, except that the body 2 is now provided with a liner component 22. The liner component 22, in particular the liner panel, covers the body 2 and the collision pin 19, so that the collision pin 19 is covered behind the liner component 22 and is therefore not visible from the outside.
[0025] Figure 4A and Figure 4B It shows along Figure 1 A cross-sectional view of the area where line AA passes through the collision pin 19 of safety device 17. Figure 4A In addition to the vehicle body 2, a baffle element 22 is shown, which covers the collision pin 19. For this purpose, the baffle element 22 extends at least in the region of the collision pin 19 spaced apart from the retaining section 18, such that the free end 21 of the collision pin 19 is spaced apart from the baffle element 22.
[0026] The collision element 13 has a recess 23 at its end 14 opposite to the collision pin 19, which, according to the present embodiment, is configured as an opening or through-hole in the collision element 13. The recess 23 has an inner profile slightly larger than the outer profile of the collision pin 19. In the closed position of the door 4, the recess 23 is opposite to the free end 21 of the collision pin 19. The door 6 has an inner liner member 24 that covers and conceals the collision element 13 on the inside of the door. Therefore, the inner liner member 24 also extends over the recess 23, making it invisible from the outside. The inner liner member 24 extends parallel to the liner member 22 in the region of the retaining section 18, allowing the door 6 to be positioned particularly close to the vehicle body 2 in the closed position. In the closed position, it is preferable to... Figure 4A As shown, a gap is maintained between the inner baffle member 24 and the baffle member 22.
[0027] In a side collision or side impact in the area of door 6, the following functions of safety device 17 are derived, such as, especially by means of Figure 4B As shown.
[0028] For example, Figure 4BAn exemplary illustration shows a safety device 17 in an activated or deformed state after a side impact. Due to the side impact, the door 6 is subjected to a force in the direction of the interior space of the vehicle 1, which deforms the door 6. Here, in particular, the impact element 13 is compressed into the interior space of the vehicle, thereby displacing the free end 14 in the direction of the impact pin 19. If the force generated by the side impact is large enough, the impact element 13 is displaced against and compressed against the retaining section 18, such that the impact pin 19 cuts through the retaining member 22 and the inner retaining member 24 and is pushed into the recess 23 of the impact element 13. For this purpose, the impact pin 19 preferably has a cutting edge 25 at its free end 21, which is configured to cut through the retaining member 22 and the retaining member 24 in such an impact or side impact. By engaging the collision pin 19 in the recess 23, a form-fit connection is now created between the collision element 13 or the door 6 and the collision pin 19 or the body 2. Through this form-fit connection, the door 6 is locked at the end of the collision pin 19 away from the pivot hinge 10 and is prevented from being pressed into the vehicle interior space.
[0029] Safety device 17 thus ensures that, in a side collision, door 6 cannot move into the vehicle's interior space. This advantageously reduces the risk of injury to vehicle occupants. The arrangement of the retaining pin and the recess 23 ensures that, on the one hand, safety device 17 is not visually visible, and on the other hand, occupants will not be injured or have their clothing damaged when getting in or out of the vehicle at the retaining pin.
[0030] The current embodiment relates to a pivotable door 6, while according to another embodiment (not shown), the door is movably supported on the vehicle body 2, particularly on the longitudinal beam 15. Here, at least one impact pin 19 is preferably arranged in the transition or transition area between one of the vehicle pillars 7, 9, 11 and the longitudinal beam 15.
