A dual sided recliner assembly which minimizes interference and wear of the teeth of the engaging parts while providing a compact and enclosed construction for longer service life. The backrest of the seat is secured between opposed moving plates, each one including a recessed area having two arcuate slots and an arcuate rack along one of the edges within the recessed area. The width of the opening provided in one of the slots is uniform whereas the width of the opening within the other slot is irregular such that a portion of its length is wider than the other portion. The moving plate is rotatably supported on a stationary plate and a coil power spring biases the moving plate toward a fully reclined forward position. The stationary plate also includes a recessed area which is opposed to the recessed area in the moving plate when the plates are assembled. A pawl is contained between the recesses of the plates for movement therein. The pawl is moved into engagement with the rack by a cam that is mounted on a spring biased camshaft. When the handle is rotated, the pawl is released from the rack thereby permitting automatic movement of the backrest toward a fully reclined forward position. During this movement, the narrow portion of the irregularly shaped slot moves into engagement with the camshaft thereby causing translational movement of the camshaft for maintaining a spaced relation between the pawl and rack until the backrest is returned to its upright position.
