Embodiment Construction

[0028] figure 1 A motor vehicle lock 1 is shown, which is installed in a motor vehicle body 2 . The lock bracket 3 and the lock bow 8 can be seen, which has the two bow legs 4 , 6 and the bow bridge 5 and the recess 7 formed therebetween. figure 2 The corresponding content is shown more clearly.

[0029] In addition to the lock bracket 3 , a locking mechanism 10 is shown which comprises, inter alia, a door latch 11 with a receptacle 12 and a pawl 13 . In the example shown, the pawl 13 has been inserted so that the door latch 11 cannot be moved out of the position shown. In this position, loads can be caused by the different movements of the two parts, lock bracket 3 and locking mechanism 10 , so that corresponding loads and especially unpleasant noises can occur in contact area 15 .

[0030] figure 2 It is shown that the contact region 15 has a special configuration or machining in order to create a special surface structure 16 . The entire outer wall 17 of the loaded bow...

Abstract

A low-noise embodiment of a motor vehicle lock, which optimally transmits the forces that occur when driving a motor vehicle, is provided with a lock bow (8) having a specially designed bow leg (4). The outer wall (17) of the bow leg (4) has a surface structure (16), particularly in the contact area (15), consisting of grooves (19, 20) running obliquely to the longitudinal axis (22) or of corresponding webs (21). In addition to a special design of the grooves (19, 20) and the webs (21) on the outer wall (17) of the bow leg (4), it is thus possible to provide the rotary catch (11) in the receiving section (12) with such a surface structure (16) or similar in order to be able to transmit optimal pressure loads or other loads and in order to significantly minimize noise that may occur in this area when the vehicle is in motion.

Description

technical field [0001] The invention relates to a motor vehicle lock. Background technique [0002] Motor vehicle locks with a lock carrier and a door latch are basically known, the lock carrier often being designed as a wire and fastened to a base plate. Lock brackets are likewise known which are formed from sheet metal, for example by punching out or bending out subregions of the sheet metal. It has to be considered in the technical design that the lock bracket can also effectively absorb the received forces for secure locking of the motor vehicle door. For motor vehicle locks in vehicle construction, a locking mechanism consisting of a door latch and pawl is usually used to lock a lock bracket fastened to the body. Thus, motor vehicle locks are usually fastened to a motor vehicle door, a tailgate or another movable vehicle part. In the closed state of such a motor vehicle lock, the door latch acts with its support arm on a particularly arc-shaped lock bracket. In this...
