A spring loaded latch mechanism for controlling tilting movement of a seat back relative to a seat frame to which it is pivoted, includes an elongated rod having one toothed face and only one end connected to the seat, a latch frame connected to the seat and supporting the other end of the rod for reciprocation therewithin, a pawl adapted to releasably engage the teeth, a manually-operated handle, and a cam interconnecting the handle and the pawl to drive the pawl into and from engagement. In one embodiment similar latch mechanisms are provided, one on each side of the seat with the mechanism opposite to the handle being a slave having a free-floating cam plate and a lever plate driven by the operator, actuation of the slave cam plate resulting from the lever plate being rotated thereagainst independently of the master latch mechanism on the handle side.
