Abstract

A motor vehicle door lock, particularly a motor vehicle bonnet lock, includes a ratchet mechanism which substantially consists of a rotary latch and a pawl. The ratchet mechanism interacts with a lock retainer pin on a vehicle bonnet. A retention element is additionally provided which holds the pawl in a retention position, raised from the rotary latch, during unlocking of the bonnet. The lock retainer pin continues to engage in the rotary latch when in said retention position. During a first opening process which proceeds from the retention position, the lock retainer pin transfers the retention element into a release position that releases the pawl. During a subsequent bonnet closing process, the pawl can thus engage in the rotary latch, which can be pivoted without exertion of force by the lock retainer pin at least into the hold position.
