Abstract
A rotary latch assembly for a vehicle door includes a rotor and a catch mounted between front and rear latch plates with a spring bias for movement between opening and closing positions. A noise dampening bumper resides between the plates to engage the rotor during opening and closing movements for soft opening and closing. An actuator barrel, for releasing the catch from the closed position to the open position, is snap fit between the plates, to eliminate use of a mounting clip.
Claims23
A latch assembly for a door pivotally mounted to a door frame on a vehicle, comprising:
- first and second latch plates connected together by first and second axles;
- a catch mounted on the first axle for reciprocal rotation;
- a rotor mounted on the second axle for reciprocal rotation between a closed position adapted to capture a striker on the door frame of the vehicle;
- a bumper between the plates to engage the rotor and thereby dampen sound from the rotor when the rotor moves to the open position releasing the striker.
A latch assembly for a vehicle door mounted in a door frame for movement between open and closed positions, with a striker on the door frame, the latch comprising:
- first and second plates connected by first and second axles;
- a catch on the first axle;
- a rotor on the second axle;
- and
- an actuator barrel rotatably mounted between the first and second plates with resilient tabs.
A spring for a vehicle door latch assembly having a rotor and a catch mounted on respective axles, comprising:
- a spring member formed with opposite loop ends extending in opposite rotational directions for mounting on the axles;
- and
- a V-shape formed in the spring member between the loop ends.
