Abstract:
A vehicle seat has a seat back and a seat cushion and a pair of recliners hingedly mounting the seat back to the seat cushion providing pivotal movement of a seat back relative to a seat cushion. Each of the recliners has a guide plate configured to be mounted to the seat cushion and a toothed plate rotatably assembled to the guide plate. The toothed disc has a flange having a series of internal teeth thereon. A plurality of pawls is mounted between the toothed plate and the guide plate. The pawls each has a toothed surface and is moveable between a locked position with the toothed surfaces engaging the series of teeth to lock the toothed plate relative to the guide plate, and an unlocked position with the toothed surfaces spaced from the teeth of the guide plate to allow movement of the toothed plate relative to the guide plate. A plurality of guides extends from the guide plate, guiding the pawls between the locked and unlocked positions. A cam is rotatably mounted between the guide plate and the toothed plate. The cam has a cam surface defined by a plurality of lobes for selective engagement with the pawls, selectively moving the pawls between the locked and unlocked positions. A spring continuously biases the cam, urging the pawls toward the locked position. A bushing is secured to the cam. The cam and the bushing have a lost motion connection therebetween. A rod extending through the bushing on each of the recliners to gang the recliners together for simultaneous operation. The guide plate and the toothed plate have abutments that limit relative rotational travel therebetween.
