  The object of the invention is to further study in such a known striker device for vehicle locks, in particular for bonnets, to realize a device which is advantageous for pedestrian protection while maintaining adjustability.

This problem is solved by the features described in claim 1. The subject matter recited in the dependent claims is in an advantageous form.
According to claim 1, there is provided a vehicle lock striker device, in particular for a bonnet, provided with a striker having at least one vertical striker and one horizontal striker. Furthermore, the striker device includes a receiving plate with at least one receiving opening for receiving at least one vertical striker. According to the invention, at least one receiving opening, when the bearing element is subjected to a load in the compression direction beyond a certain threshold, especially when a pedestrian collides, pushed by receiving off the plate, whereby The bearing elements are coupled so that the striker travel path is released.

  In addition, the striker is dimensioned so that the necessary tensile forces and moments that are generated functionally are received and the coupling is released only when the compressive load exceeds a certain threshold. This is advantageous.

  Detachable bearing elements required for such functions, such as rivet nuts, are simple and low-cost structural elements that result in improved pedestrian protection of the invention that allows for pedestrian collisions near the striker lock. Even in combination, the cost does not actually increase.

The bearing element is basically formed by a bearing bush, for example, which is coupled to the receiving opening, for example by a snap coupling. However, a form in which the bearing element is formed as a rivet nut is particularly preferred. In this case, the rivet connection is designed such that when a load exceeding a certain threshold is applied in the compression direction, the rivet nut is pushed and disengages from the receiving plate, thus releasing the movement path of the striker. By making the rivet connection in this way, a bearing element structure with a reliable and advantageous dimension is provided, and in addition, it can be handled easily in terms of manufacturing technology. On the one hand, in order to ensure that the necessary tensile forces and moments are received by the striker bearings, on the other hand, the rivet connection can be applied to a certain, in particular appropriate release from a dynamic compressive load . It is proposed to use a rivet nut with two rivet heads sandwiching the front and back surfaces . In this case, the diameter of the rivet head that requires a compressive load is reduced to push the rivet nut, and in some cases, a void on the rivet head contributes to it.

  According to a particularly preferred specific embodiment, the striker has a U-shaped basic shape with two vertical strikers and one horizontal striker. Such a U-shaped striker can be used in many different striker devices, giving the striker device high stability.

  Furthermore, it is particularly preferred that the at least one longitudinal striker is held on the bearing element by a tight connection and / or a static friction connection, in particular a screw connection. Such a height-adjustable striker device can be easily set and adjusted because, for example, the distance from the lateral striker to the receiving plate is formed for tolerance correction. In this connection, with respect to the U-shaped striker configuration, the first vertical striker is held on the bearing element in a height-adjustable manner, and the second vertical striker is arranged freely movably, for example in another receiving opening. Is particularly advantageous.

According to a further preferred embodiment, one of the vertical striker having a male screw is held in the receiving apertures of the rivet nut associated with an internal thread, whereas the second vertical striker no rivet nuts other accepted It is movably inserted into the opening and guided. Only a quick assembly and adjustment is performed with one vertical striker, in which case the second freely guided vertical striker also serves as an anti-twist.

  Therefore, the vertical striker held by the bearing element is rotatably coupled to the horizontal striker, and the vertical striker is provided with a tool mounting portion for screw connection. A rotary bearing hole is provided at the end of the horizontal striker for rotatable connection, and a vertical striker is set in the rotary bearing hole.

  However, instead of an embodiment in which only one vertical striker is adjustably bearing, e.g. screwed, two vertical strikers are provided with e.g. However, embodiments with rivet nuts with internal threads can also be used.

The at least one receiving opening is pushed away from the receiving plate when the bearing element is subjected to a compressive load exceeding a certain threshold , especially when a pedestrian collides, so that the path of movement of the striker is reduced. The bearing elements are coupled so that they are released. This provides a device that is convenient for pedestrian protection while maintaining adjustability.

The perspective view of the striker apparatus for vehicle bonnet locks attached to the receiving plate is shown. Fig. 2 shows a section along the line AA in Fig. 1;

Embodiments of the invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a striker device 1 for a vehicle bonnet lock attached to a receiving plate.

  For this purpose, the striker 3 is fixed to the receiving plate 2 so as to be adjustable. As is apparent from the sectional view of FIG. 2, the striker 3 has a U-shaped basic shape having two vertical strikers 4, 5 and one horizontal striker 6.

  The receiving plate 2 includes two receiving openings 7 and 8 associated with the vertical strikers 4 and 5. The receiving opening 7 is fitted with a rivet nut 9 having a female screw 10 cut and fixed by a rivet head 11. The vertical striker 4 is provided with a corresponding male screw 12 and is screwed into the rivet nut 9 so that the height can be adjusted. For this purpose, a tool mounting portion 13 is attached to the head.

  On the other hand, the other receiving opening 8 is formed as a simple through-opening of the second vertical striker 5, and as a result, the vertical striker corresponds to the screw connection of the vertical striker 4 when adjusting the height of the horizontal striker 6. 5 move freely by the same amount.

  Between the horizontal striker 6 and the vertical striker 4 which can be screwed, it is rotatably coupled so that a screw motion is possible. Therefore, a rotary bearing hole 14 is provided at a corresponding end of the horizontal striker 6, and the vertical striker 4 is inserted into the end of the horizontal striker 6 through the hole. In addition, the horizontal striker 6 is supported in the vertical striker axial direction by the support ring 15 of the vertical striker 4 and the safety ring 16 at the end of the vertical striker.

  The rivet connection between the rivet nut 9 and the rivet head 11 is designed and dimensioned so that the necessary tensile forces and moments that are functionally generated in the striker 3 can be reliably received and introduced into the receiving plate 2. On the other hand, the rivet nut 9 and the rivet head 11 are pushed in when the compressive stress exceeds a predetermined threshold, particularly when a pedestrian collides with the lock, and the rivet nut 9 is connected to the receiving plate 2. As a result, the movement path of the striker 3 becomes free, and the entire striker device is formed conveniently for pedestrian protection.

  INDUSTRIAL APPLICABILITY The present invention can be used for a vehicle lock striker device for automobiles, particularly for bonnets.
