Patent ID: 6997488

Claim:
A rotary-latch lock ( 1 ) having a rotary latch ( 6 ) which is retained in a locked position by a catch ( 9 ), and having an actuating member ( 19 ) which can be displaced by an electric motor from a starting position into an actuating position and serves for pivoting the catch ( 9 ) into a release position, the release position of the catch ( 9 ) enabling the rotary latch ( 6 ) to pivot into an open position, wherein a release member ( 24 ) is operative by means of the rotary latch ( 6 ), as the latter rotates into the open position, to release the actuating member ( 19 ) for the catch ( 9 ) for return displacement into the starting position; and wherein the actuating member 19 comprises a worm helix ( 22 ) engaging with the release member ( 24 ) during an unlocking of the latch ( 6 ), the release member ( 24 ) displacing the worm helix along a shaft ( 15 ) during a rotation of the shaft by the motor for driving the catch ( 9 ) into the release position, wherein rotation of the latch into the open position disengages the release member ( 24 ) from the worm helix allowing the worm helix to be displaced back by spring force to the start position.
