Abstract
A lock suitable for use in a motor vehicle door has a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device wherein the rotary latch cooperates with the locking wedge to be locked in a locking position by the pawl. Upon actuation of a manipulator, the setting device brings the pawl electrically at least into one opening position. The transmission device brings the pawl into its opening position by actuation of the manipulator over a displacement range which is greater than a displacement range of an electric unlocking.
Claims22
A lock suitable for use in a motor vehicle door, comprising:
- a rotary latch, a locking wedge, a pawl, a setting device, and a transmission device;
- wherein said rotary latch cooperates with said locking wedge to be locked in a locking position and held in said locking position by said pawl;
- wherein said setting device includes motorized means, responsive to operation of a manipulator along a first path of travel, for driving said pawl to an opening position which frees said latch from said locking position, said manipulator comprising a handle;
- said transmission device interconnects said manipulator with said pawl, and includes means responsive to operation of said manipulator along a second path of travel, longer than said first path of travel, for driving said pawl to said opening position;
- and
- said setting device is coupled to said pawl by a mechanical connection permitting said transmission device to displace said pawl to said opening position independently of a position of said setting device.
