Abstract

An emergency release device for the parking lock of a motor vehicle is described which contains an locking device (46,44,38,24,12,10) that is pressed into its engaged position by a spring element (42,50) and which can move into its disengaged position by at least one actuator (46) that is actuated by a control element (56,58) against the spring force. The locking device (46,44,38,24,12,10) can be linked with a clutch pedal located on the operator's station by releasable mechanical connecting elements (108,110,112), in such a way that it is possible to emergency-release the parking lock in case of vehicle malfunction.
