Abstract
A passenger seat with low profile seat back recline locking assembly, including a recline unit for controlling movement of the seat back and locking the seat back in a desired recline position. A hydraulic cylinder assembly is pivotally-mounted by a first end thereof to a section assembly module of the seat and by an opposite second end thereof to the seat back unit. The cylinder assembly has a longitudinally-extending axis extending in alignment with the longitudinally-extending, generally vertical plane of the seat back. An actuator is positioned astride and operatively connected to the fluid cylinder adjacent one or the other of the first and second ends thereof. An occupant-activated seat back recline control allows the occupant to maintain the seat back in a normally-locked condition relative to the seat bottom chassis and for permitting the occupant to release the normally-locked condition of the cylinder assembly by activating the seat back recline control to thus permit movement of the seat back to a desired position and deactivating the seat back recline control to lock the seat back in the desired position.
