Abstract
A lock, suitable for use in a car door, has a rotary latch which cooperates with a locking wedge, or the like, and can be locked by a locking pawl in a locking position. The pawl is actuatable by a setting device for bringing the rotary latch at least into an open position. In order to provide a lock which is of improved efficiency and is both compact in construction and operates reliably, transmission elements are arranged between the pawl and the setting device for transmitting movement of the setting device, in stepped-down fashion, to the pawl.

A lock comprising:
- a rotary latch, a locking wedge, a pawl, and a setting device;

- and
- the lock further comprises transmission elements which transmit a movement of the setting device, in stepped-down fashion, to the pawl, the transmission elements being arranged between the pawl and the setting device;
- wherein interconnections between successive ones of the transmission elements permit an opening movement of the transmission elements in response to a manipulator force applied to one of the transmission elements to release the pawl from engagement with the rotary latch;
- the step-down transmission includes at least one gear wheel and at least a first toothed segment including means on said first toothed segment for contacting said pawl, and said setting device comprises an electric motor;
