Lock for a motor vehicle
First Claim
1. A latch, for a door or flap of a motor vehicle said latch comprising a locking mechanism comprising a catch and a pawl for locking the catch when in a detent position, a lock lever for locking the pawl in its detent position when in a locking position, a release lever for opening the locking mechanism by moving the lock lever out of its locking position, and a lock contour rigidly connected to a latch case of the latch, wherein the lock contour defines a stop and a plurality of recesses that define a plurality of locking positions of the lock lever, wherein the lock contour is designed in such a way that during excessive acceleration of the release lever and/or in case of excessive acceleration of the release lever via an associated handle of a door or flap, the lock contour locks the lock lever in one of the locking positions, thereby preventing the locking mechanism from being placed in an open state.

Abstract
The invention relates to a lock, in particular for a door or opening element of a motor vehicle, said lock comprising a locking mechanism with a rotary latch, a pawl for locking the rotary latch in a detent position, preferably a blocking lever for blocking the pawl in the detent position and a release lever for opening the locking mechanism, in particular by moving the blocking lever out of the blocking position. The lock is characterized in that a safety catch device of the lock, said device comprising in particular more than one catch position, is designed to prevent the opening of the locking mechanism during excessive acceleration, in particular during excessively violent acceleration of the release lever and/or handle of a door or opening element. An unplanned opening of the lock in the event of a crash can thus be avoided.

16. A latch, for a door or flap of a motor vehicle said latch comprising a locking mechanism comprising a catch and a pawl for locking the catch when in a detent position, a lock lever for locking the pawl in its detent position when in a locking position, a release lever for opening the locking mechanism by moving the lock lever out of its locking position, and a lock contour rigidly connected to a latch case of the latch, wherein the lock lever contains a tappet that can be moved by the release lever for moving the lock lever, with a pretensioned leg of a spring resting against the tappet, wherein the inertia lever has a slotted hole designed in such a way that the tappet of the lock lever extends through the slotted hole of the inertia lever and/or facilitates a relative movement between the lock lever and the inertia lever, wherein the lock contour is designed in such a way that during excessive acceleration of the release lever and/or in case of excessive acceleration of the release lever via an associated handle of a door or flap, the lock contour locks the lock lever in a locking position, thereby preventing the locking mechanism from being placed in an open state.
