A passenger seat back recline assembly, including a seat bottom chassis including a plurality of leg modules and section assembly modules, a plurality of beam elements carrying the leg modules and section assembly modules in spaced-apart relation to each other to define a ladder frame assembly, a seat back unit pivotally-mounted between two of the section assembly modules for permitting the angle of the seat back relative to the seat bottom chassis to be varied as desired by the passenger, a recline unit for controlling movement of the seat back and locking the seat back in a desired recline position, an occupant-activated seat back recline control for maintaining 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. Respective first and second pivot tubes are provided on which the fluid cylinder assembly is mounted, the first and second pivot tubes being positioned in respective first and second pivot holes formed in the section assembly module. First and second locking spacer collars are positioned in surrounding position on respective first and second pivot tubes intermediate the section assembly module and the seat back unit pivoted thereto.
