Abstract

The invention relates to a motor vehicle door lock equipped with a locking mechanism, an actuation lever unit acting on the locking mechanism, and a catch lever. The catch lever blocks the locking mechanism at least when acceleration forces of a given magnitude occur, e.g. in case of an accident (crash), rendering the locking mechanism ineffective. According to the invention, the catch lever acts upon a rotary latch of the locking mechanism in the direction of the blocking position of the rotary latch during normal operation and in the event of a crash while allowing the rotary latch and thus the locking mechanism to be in the releasing position only during normal opening operation.
