DE1553299C - Device for preventing the opening of a motor vehicle door lock in the event of a collision - Google Patents

Description

(F i g. 4) the motor vehicle door lock is already against jumping open in the longitudinal and transverse axes of the vehicle secured in the event of an accident. By moving the fork latch 4 in the locking direction - in the Drawing to the left - the fork latch axis 5 is rotated clockwise and the lock in the Brought closed position (Fig. 5). In the pre-locking and closed position, the fork latch 4 is through a outside and inside releasable locking disk 9 held.

1 2 the device necessary spring this device , performing their task, namely a popping up of the Claim: Motor vehicle door lock in the event of a collision to prevent collision, can not meet. Device for preventing the opening 5 The object of the invention is therefore based on that of a motor vehicle door lock in the case of the problem of providing a device for preventing a collision, wherein a closing part seen on the door before the opening of a motor vehicle door lock, which has a base plate with ses the The prerequisite type in the event of an accident is to create a swiveling perpendicular to the door front wall, which consists of a few, easy-to-manufacture fork latches surrounded by a housing with io parts, which ensures a long-term operational locking disk fixed on the latch axis with little wear and tear,
This object is achieved in that the device Locking bolt attached to the body with a housing made of an approximately C-shaped retaining plate with un-locking bolt and locking bolt head rotated into a Vorrast- terer pulled up bend for reaching behind and a closed position and in this 15 of the locking bolt head consists and the upper leg positions are held by a pawl , the C-shaped retaining plate as an abutment for. the elastic wedge piece that is attached to the release locking bolt by external or internal actuation,
is bar, and wherein a raised part of the Ge is through this design of the door lock The housing of the mouth opening of the fork latch is created in a device which is made up of a few, simply closed state, which means that there is only one part to be produced, which only indicates that the housing has a C-shaped retaining plate (7) with a very low level of wear and tear in normal operation are exposed to lower levels of use and thus ensure a long, radio-lifted turn (7 a) for working in a way that is easy to understand. The construction of the locking bolt head (2 a) is made, and the tive structure of this device allows the user upper legs (7 b) of the C-shaped retaining plate 25 tion of simple, efficient production methods, (7) as an abutment for the locking bolt (1) through the a mass-produced article as used in the attached elastic wedge (3). Motor vehicle door locks are more cost-effective 'can be produced. The drawing shows an embodiment of the subject matter of the invention. It shows F i g. 1 is an end view of the motor vehicle door lock ¹ lock in closed position, F i g. 2 shows a central longitudinal section through the motor vehicle door lock according to FIG. 1,

The retaining plate 7 carries the fork latch 4, can be moved back, and wherein a raised part of the jaw opening of the fork latch in the bush 6 is rotatably attached to the retaining plate 7 via the fork latch axis 5 and bearing housing. Opposite closed state. The holding plate 7 is fastened to the base plate 8 Such a device is known, each and the end facing away from the fork latch 4 of the Gadoch the locking bolt head through a spring-loaded 55 belly axis 5 is connected to the locking disk 9 slide is engaged from behind, which leads to a disagreement. Bring the handle in the vehicle longitudinal direction of the locker The mode of action of this motor vehicle door verb from the closure part in the event of a combination is the following: collision is avoided. The spring-loaded and \ yi _e in FIG. 3, the two face each other However, when the slide is open, the parts which are arranged to be displaceable perpendicularly to the locking bolt are subject to the locking mechanism, since it is opposite to each other when the vehicle door is opened. When the door is closed and the closing movement is also a certain one, the fork latch 4 engages around the locking bolt 2 and the distance to and fro, which is limited by the spring travel, of the upper leg 7 b of the holding plate 7, which is moved, results in increased wear. elastic wedge 3 to the plant. The turn The uncertainty of such a device lies 65 7a engages behind the locking bolt head la and the öffdarin that the critical state of wear is not recognized by the fork latch 4 except for a gap by the user of a vehicle, this opposite bend Ta closed and that with one Break of the sen for safe function.
