Problems solved by technology

[0007] A problem that can arise in motor vehicle locks with a memory function is that, when the locking mechanism is locked, the pawl and / or the trigger lever are guided by the rotary fork and, depending on the actuation speed of the rotary fork when closing, the cause shock
If the rotary locking fork is accelerated too strongly during closing, this can lead to the fact that the pawl and / or the actuating lever are subjected to shocks or forces in such a way that the rotary locking fork and / or the actuating lever can be introduced into the function of the storage lever
In this case, the locking of the locking mechanism may be prevented due to the function of the storage lever

Embodiment Construction

[0032] exist figure 1 The motor vehicle lock 1 , in particular the tailgate lock 1 , is shown in plan view without the hatch. The motor vehicle lock 1 has a rotary fork 2 , a pawl 3 , a trigger lever 4 and an electric drive 5 . Furthermore, the switching means 6 , 7 , the lock housing 8 and the gear wheel 9 with the control contour 10 can be seen. A worm 11 is arranged between the electric drive 5 , preferably an electric motor, and the gear 9 , so that the gear 9 can be actuated electrically.

[0033] exist figure 1 The open position of the rotary lock 2 is shown in . When the door or the hatch is closed, the motor vehicle lock 1 is moved relative to a lock stop (not shown), so that the turning lock fork performs a movement in the direction of the arrow P in the counterclockwise direction. In the open position, the rotary catch 3 bears against the contact contour 12 of the rotary catch. The pawl 3 is preferably spring-loaded against the rotary lock 2 , wherein the pawl 3...

Abstract

The invention relates to a motor vehicle lock (1) comprising a locking mechanism that includes a rotary latch (2), at least one pawl (3), a triggering lever (4) that allows the pawl (3) to disengage from the rotary latch (2), and a latching lever function that allows the triggering lever (4) which is actuated for disengaging the rotary latch (2) to be secured in an actuated position; the triggering lever can be guided by the rotary latch (2) only in some sections.

Description

technical field [0001] The invention relates to a lock for a motor vehicle, comprising the functions of a locking mechanism, a trigger lever, and a storage lever, said locking mechanism having a rotary locking fork and at least one pawl, by means of which the trigger lever can disengage the locking claw from engagement with the rotary locking fork, by means of a storage lever The function is to be able to fix the trigger lever in the actuated position, which is actuated for disengagement from the rotary latch. Background technique [0002] In order to increase functional safety in motor vehicles, motor vehicle locks installed in hatches, doors, sliding doors or hoods have various functions. One of these functions is to prevent reclosing or incomplete opening in the case of an open locking mechanism in a motor vehicle lock. [0003] Especially in the following cases-wherein the lock is a rear hatch lock, it may occur that after the lock is opened electrically or manually, th...
