ABSTRACT:
A double-sided reclining apparatus comprises a first reclining device equipped with a reclining-lever handle and a second reclining device, each comprising a base and an arm having an inner toothed portion, a pivotal shaft through which the arm is rotatably supported on the base, and a set of cam and toothed block in cam-connection. The toothed block has a second toothed portion meshable with and unmeshable from the first toothed portion. The cam and the toothed block cooperate with each other to cause meshing/unmeshing action of the reclining apparatus. The cam and the toothed block have a plurality of cam-connection points in the cam-profile surface of the cam and the cam-contour surface of the toothed block. The pivotal shaft is fitted into a central slot of the cam and has a noncircular irregular-shaped cross section to drive the cam. A predetermined clearance is provided all around between the inner periphery of the central slot of the cam and the outer periphery of the pivotal shaft.
