Abstract
A locking device for trunk lids comprises a latch for engaging with a striker, a ratchet for maintaining the engagement between the latch and the striker, an output member rotating by an electric motor against resilient force of a return spring, a moving bar provided between the ratchet and the output member so as to slide in a lateral direction, the moving bar having one end connected to the output member and the other end connected to a key cylinder, an engaging portion provided with the moving bar for engaging with the ratchet to release the ratchet from the latch when the moving bar laterally slides from an original position by the rotation of the output member or the key cylinder. The moving bar is restored to the original position by the resilient force of the return spring after the ratchet is disengaged from said latch.
Claims6
A locking device for trunk lids comprising:
- a base plate having a circumferential wall;
- a latch rotatably mounted on the base plate for engaging with a striker, said latch having a step portion;
- a ratchet rotatably mounted on the base plate and having a pawl for engaging with the step portion of said latch;
- a spring provided between said latch and said ratchet;
- and
- a ratchet cover substantially covering said ratchet and having a first cushion portion and a second cushion portion with sufficient elasticity;
- wherein said first cushion portion collides against said latch before said pawl engages with said step portion, and said second cushion portion collides against said circumferential wall when said ratchet is released from said latch;
- wherein said first cushion portion and said second cushion portion are respectively arranged on opposite sides of said ratchet.
A locking device for trunk lids comprising:
- a base plate;
- a latch rotatably mounted on the base plate for engaging with a striker;
- a ratchet rotatably mounted on the base plate for maintaining the engagement between the latch and the striker by engaging with the latch;
- an output member mounted on the base plate, said output member being rotatable between a first position and a second position;
- a return spring for returning the output member to the first position from the second position;
- an electric motor for rotating the output member toward the second position against a resilient force of the return spring;
- an elongated moving bar provided between the ratchet and the output member, said elongated moving bar having one end connected to the output member and the other end connected to a key cylinder and being slidable parallel to a longitudinal axis of the elongated moving bar only in a single straight line between an initial position and an operating position by rotation of the output member or the key cylinder;
- and
- an engaging portion provided with the elongated moving bar for engaging with the ratchet to release the ratchet from the latch when the elongated moving bar slides from the initial position to the operating position by the rotation of the output member or the key cylinder;
- wherein said elongated moving bar is returned to the initial position by the resilient force of the return spring after the ratchet is disengaged from the latch.
