Abstract:
A passenger seat back recline assembly, comprising:(a) a seat bottom chassis including a plurality of leg modules and section assembly modules; (b) a plurality of beam elements carrying said leg modules and section assembly modules in spaced-apart relation to each other to define a ladder frame assembly; (c) a seat back 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; (d) a recline unit for controlling movement of the seat back and locking the seat back in a desired recline position, said recline unit comprising a fluid cylinder pivotally-mounted to said section assembly module and extending between said section assembly module and said seat back; (e) 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 fluid cylinder 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; (f) respective first and second pivot shafts on which the seat back and the fluid cylinder are respectively mounted, said first and second pivot shafts being positioned in respective first and second pivot holes formed in the section assembly module; (g) a first locking spacer collar positioned in surrounding position on said first pivot shaft intermediate the section assembly module and the seat back pivoted thereto; and (h) a second locking spacer collar positioned in surrounding position on respective said second pivot shaft intermediate the section assembly module and the fluid cylinder pivoted thereto.
