An automobile seatback subassembly for mutually securing an automobile seat and seat back, and comprising a complimentary pair of mutually interlocking members including an elongated member having a slide with a notched profile intermediate leading and trailing ends thereof, and a channel member comprising a wall arrangement defining an open ended channel for receiving a predetermined maximum length of the mounting member, in axial inter-fitting relation therein. The channel member includes a rotationally biased eccentric cam arranged on a pivot located adjacent the channel with a radially outermost extent of the cam normally biased into inter-fitting relation within the channel in transverse register with the notched profile of the elongated mounting member when the latter is inter-fittingly arranged within the channel. The cam is operably rotatable out of that interfering relation in order to permit the insertion and the withdrawal of the mounting member in the manner described below. The notched profile consists of an axially extending, non-recursive concave spiral surface having a radius of curvature which increases with increasing distance from the leading edge.

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.
