Rotary-latch lock
First Claim
1. 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.

Abstract
The invention relates to 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 is intended for pivoting the catch (9) into a release position, in which the rotary latch (6) can pivot into an open position. In order to optimize the functioning of the rotary-latch lock, the invention proposes to provide a release member (24) which by means of the rotary latch (6), as the latter rotates into the open position, releases the actuating member (19) for the catch (9) for return displacement into the starting position.
