Abstract
Lock including at least one latch (2) which can move against a spring (8) between a locked position and a retracted position, this displacement of the latch taking place against the spring which thus passes from a position known as the rest position to a position known as the tension position, this also including a means (6, 7) for holding the spring (8) in its so-called tension position, and a means (17) actuated by the keeper when it engages with the latch and actuating this holding device so as to release the spring, the lock being characterized in that it includes a means (26) actuated when the door is being opened so as to play a part in tensioning the spring (8).
Claims11
A lock for use on a motor vehicle door, the lock comprising:
- a keeper;
- a spring;
- a latch pivotally mounted between a locked position and an unlocked position, the latch engaging the keeper in the locked position and disengaging from the keeper in the unlocked position, the latch displacing the spring from a rest position to a tension position as the latch pivots from the locked position toward the unlocked position;
- tensioning means for placing the spring in the tension position, the tensioning means disposed on the latch and being actuated when the door is opened;
- retention means for holding the spring in the tension position when the latch is in the unlocked position;
- and
- releasing means for releasing the retention means so that the spring is released from the tension position urging the latch to pivot toward the locked position, the releasing means disposed on the latch and being actuated when the keeper engages the latch as the door is closed.
A lock comprising:
- a keeper;
- a latch pivotally mounted between a locked position and an unlocked position, the latch constructed and arranged to engage the keeper in the locked position and to disengage from the keeper in the unlocked position;
- a spring;
- a pusher disposed between the latch and the spring, the pusher constructed and arranged to displace the spring to a tension position as the latch pivots from the locked position toward the unlocked position and to retain the latch in the unlocked position;
- and
- a lever constructed and arranged to release the pusher and to pivot the latch from the unlocked position toward the locked position, the spring being released from the tension position to urge the pusher against the latch to pivot the latch toward the locked position.
