Description

BRIEF DESCRIPTION OF THE DRAWING

(1) FIG. 1 is a simplified perspective view of a motor vehicle body lock 5 which is installed on a symbolically illustrated motor vehicle 1 and which has a lock striker 10.

DETAILED DESCRIPTION OF THE DRAWING

(2) The motor vehicle body lock 10 of this exemplary embodiment is fastened by means of screws (not shown here) to a partially shown body component 15 formed as a metal sheet, for example of a front hood, and serves for the connection of a hook 20, which is illustrated merely symbolically here.

(3) For this purpose, the motor vehicle body lock 10 has a striker plate 25 which comprises a first striker plate section 25-1, which is adjacent to the body component 15, and a second striker plate section 25-2, which is substantially parallel to said first striker plate section. The first striker plate section 25-1 and the second striker plate section 25-2 are connected to one another at a connecting section 25-3 such that, as seen in side view, they form a U-shaped configuration.

(4) In the second striker plate section 25-2, there are situated apertures 30-1 and 30-2, which are arranged in alignment with apertures 35-1 and 35-2 respectively which are arranged in the first striker plate section 25-1. According to this exemplary embodiment, a crash securing means 37 in the form of a T-shaped bolt is arranged in the apertures 30-2 and 35-2. The first end 37-1, situated at the bottom in the FIGURE, of the crash securing means 37 is fastened in the recess 35-2. The second end 37-2, situated at the top in the FIGURE, of said crash securing means is formed as a head part and is mounted in the corresponding recess 30-2 such that, in the normal situation of the motor vehicle body lock 10 shown here, said second end does not make contact with the second striker plate section 25-2. By contrast, in the crash situation (not shown here) of the motor vehicle body lock 10, the bottom side of the second end 37-2, in head form, of the crash element 37, lies against the second striker plate section 25-2 and supports the latter. For this purpose, the outer diameter of the second end 37-2 is advantageously configured to be substantially larger than the outer diameter of the recess 30-2. For the purposes of facilitated installation and removal of the crash securing means 37, a tool engagement section 37-3, in which a tool (not shown here) can engage or act, is provided on the second end 37-2. Alternatively or in addition, at least one tool engagement section may be provided on the outer side of the second end 37-2.

(5) The motor vehicle body lock 10 furthermore has a striker 40 with a first striker limb 40-1, a second striker limb 40-2 parallel to said first striker limb, and a striker section 40-3, on which the hook 20 engages and exerts a load F when the motor vehicle body lock 10 is closed. The first striker limb 40-1 and the second striker limb 40-2 are oriented symmetrically with respect to one another and with respect to a respective edge section 45 of the second striker plate section 25-2 (cf. plane of symmetry S). The striker section 40-3 projects substantially orthogonally with respect to said striker limbs and with respect to the second striker plate section 25-2.

(6) The first striker plate section 25-1 comprises a first extreme end 50-1 and, spaced apart from the latter, a second extreme end 50-2, which extreme ends project in each case substantially orthogonally with respect to the former in the same direction as the striker section 40-3. A first end section receiving means 55-1 illustrated in transparent form is fastened by a fastening means 60-1 to the first extreme end 50-1 which is on the left in the FIGURE. A second end section receiving means 55-2 illustrated in transparent form is fastened by a further fastening means 60-2 to the second extreme end 50-2 which is on the right in the FIGURE. The first end section receiving means 55-1 and the second end section receiving means 55-2 support in each case one first end section of a spring means 65 which is formed in the manner of a cantilever and which is manufactured from a spring steel. The spring means 65 has, in its central region, a damping means 70 which is formed from a plastic or rubber and which is received under preload in a connecting section 75 situated on the second striker plate section 25-2; the connecting section 75 is consequently formed as a receptacle 80. Those ends of the first striker plate section 25-1 and of the second striker plate section 25-2 which are remote from the connecting section 25-3 are elastically operatively connected to one another by means of said connecting section.

(7) A desired vibrational characteristic of the motor vehicle body lock 5 according to the embodiments of the invention can advantageously be easily generated through suitable selection of the materials and geometry of the above-described elements, in particular of the dimensions thereof.
