Abstract
The problem addressed by the invention is that of being to switch a motor vehicle lock from normal operation to emergency or disruption operation within an especially short time and/or with the least possible expenditure of electrical energy. This problem is solved in that a lock for a motor vehicle having a lock mechanism and an electric drive is provided such that the lock can be electrically opened in normal operation. The lock has an additional operating state, called disrupted operation. In disrupted operation, the lock can be opened mechanically, which is not possible in normal operation. The lock comprises a mechanical energy accumulator for switching the lock from normal operation to disrupted operation.
Claims15
Latch, especially for a motor vehicle with a latch mechanism, whereby the latch comprises two different operating states, i.e. normal operation, in which the latch can be electrically opened, and breakdown operation, in which the latch can be mechanically opened, characterized in that the latch comprises a mechanical energy storage device, with which the latch can be shifted from normal operation to breakdown operation.
