Abstract: A disengageable cylinder for a motor vehicle lock mechanism includes a fixed stator, a sleeve, a rotor, a driver, and an indexer. The sleeve is mounted in rotation about its axis in the stator, and is fixed axially with respect to the stator. The rotor is mounted in rotation in the sleeve and is fixed axially in the sleeve.

Abstract: A disengageable cylinder for a motor vehicle lock mechanism includes a fixed stator, a sleeve, a rotor, a driver, and an indexer. The sleeve is mounted in rotation about its axis in the stator, and is fixed axially with respect to the stator. The rotor is mounted in rotation in the sleeve and is fixed axially in the sleeve. The driver is connected in translation on the rotor. The indexer, which can move axially between rest and disengagement positions, is connected in translation on the stator. When an appropriate key is inserted in the rotor, the driver couples the rotor and a cam actuator in rotation, releasing the lock. When an inappropriate key is inserted, the rotor and sleeve rotate, causing the indexer to move toward the cam actuator. Because the indexer is rotationally immovable as a result of its connection with the stator, the cam actuator cannot rotate.

Abstract: A disengageable lock for a motor vehicle locking system includes a fixed stator, a sleeve, a rotor, a driver, and an indexer. The sleeve is mounted rotatably in the stator and is fixed axially relative to the stator. The rotor is mounted rotatably in the sleeve and is fixed axially in the sleeve. The driver is connected in disengageable rotation on the rotor. The indexer, which is axially mobile between rest and disengagement positions, is connected in translation in the stator by ribs surrounding the sleeve. When an appropriate key is inserted in the rotor, the driver couples the rotor and a cam actuator in rotation, releasing the lock. When an inappropriate key is inserted, the rotor and the sleeve rotate, causing the indexer to move toward the cam actuator. Because the indexer is rotationally immovable as a result of its connection with the stator, the cam actuator cannot rotate.

Abstract: A lock for an opening panel. The lock includes a rotary bolt with first and second locking notches, a strike which can be engaged in the bolt in order to lock the opening panel, a retaining pawl including at least one tooth which co-operates with the locking notches of the bolt in order to lock same in relation to the first or second locking notch, and a switch which is controlled with a control lever. The switch has two states which indicate if the lock is open or closed.
