Embodiment Construction

[0040] exist figure 1 Shown in the locking device of the lock of motor vehicle, this locking device comprises rotating locking fork 1, locking pawl 2, deadlock bar 3, and they are fixed on the lock box 4 in a rotatable manner. The rotary locking fork 1 can pivot around its axis 5 . The pawl 2 can pivot about its axis 6 . The deadlock lever 3 can pivot about its axis 7 . It should be noted that the invention is described on the basis of a lock comprising a plurality of claws, a so-called multi-claw locking device. However, it is clear that the invention does not only relate to multi-jaw locking devices, but can also be transferred to all other locks with locking devices.

[0041] The locking pawl 2 locks the rotary latch 1 with its locking surface 8 , which rests with the locking surface 9 on the locking surface 8 of the locking pawl. The relative position of the locking surfaces 8 , 9 is selected in this exemplary embodiment in such a way that turning the locking fork 1 in...

Abstract

The invention relates to a lock for a door or flap, comprising a locking mechanism that consists of a rotary latch (1) and at least one pawl (2) for locking the rotary latch (1), the rotary latch (1) when in the detent position preferably initiating an opening moment in the pawl (2). The design of the rotary latch (1) is such that said latch is deformed under excessive stress in the locked state in such a way that an engagement between the pawl (2) and the rotary latch (1) is maintained or increases. A lock of this type will not open even under excessive stress.

Description

technical field [0001] The invention relates to a lock for hatches or doors having the features of the preamble of claim 1 . A lock of the aforementioned type is known from document DE 10 2008 061 524 A1. The door or hatch may be a door or hatch of a motor vehicle or a building. Background technique [0002] The lock mentioned at the outset has a locking device which comprises a rotary locking fork and at least one locking pawl, with which the rotary locking fork can be locked in the closed position via the locking pawl and the locking surface of the rotary locking fork. Locking surfaces are those surfaces of the rotary catch and pawl which abut against each other for locking the locking device, so that they overlap. In the closed position, turning the locking fork can hold a stop of the door or hatch so that the door or hatch cannot be opened. If the rotary catch is in the open position, the stop can be released from the locking device and the door or hatch can be opened...
