Patent ID: 7543861

Claim:
A lock for an opening on a motor vehicle, comprising: a latch ( 3 ); a pawl ( 5 ) capable of retaining the latch ( 3 ) in a position corresponding to a closed state; an opening lever ( 12 ) movable between an opening position and a rest position upon actuation by a user; a locking lever ( 16 ) moveable between a first position corresponding to an unlocked state and a second position corresponding to a locked state, a connecting rod ( 17 ) connecting the locking lever and the opening lever, said connecting rod being displaceable between a first active position for operatively engaging the opening lever ( 12 ) to the latch ( 3 ) to establish the unlocked state and a second inactive position for operatively disengaging the opening lever ( 12 ) from the latch ( 3 ) to establish the locked state in response to displacement of the locking lever ( 16 ) between the first and second positions, a blocking member ( 28 , 29 ) on a dummy pawl ( 8 ) adjacent to and mechanically connected to the locking lever for blocking the connecting rod in the first active position, said dummy pawl ( 8 ) adapted to move said pawl ( 5 ), and an elastic device ( 21 ) storing a locking energy when the blocking member blocks the connecting rod ( 17 ) in the first active position and the locking lever ( 16 ) is moved from the first position to the second position while the opening lever ( 12 ) is in the opening position, wherein movement of the opening lever ( 12 ) from the opening position to the rest position unblocks the connecting rod from the blocking member and causes a release of the locking energy to displace the connecting rod from the first active position to the second inactive position.
