DEVICE FOR LOCKING AND UNLOCKING A FUNCTIONALLY ESSENTIAL COMPONENT OF A MOTOR VEHICLE

The invention relates to a device for locking and releasing a functionally essential component of a motor vehicle, having a locking bolt movably supported between a locked position and an unlocked position of the functionally essential component; a transmission, which is mechanically and effectively connected with the locking bolt to enable the locking bolt to be transferred between the locked position and the unlocked position; and a detection unit having a slider element for moving a signal generator and at least one first sensor element with the fixed position for detecting at least one state of the slider element; wherein the slider element is mechanically and effectively coupled to the transmission to transfer the slider element between a stationary state and a detection state, the signal generator and the first sensor elements are spaced apart in a stationary state, and the signal generator is in the detection region of the first sensor elements in the detection state. The detection unit has a spring el
