ABSTRACT:
A double-sided reclining apparatus comprises outside and inside reclining devices, 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 cam and the toothed block cooperate with each other to cause meshing/unmeshing action of the reclining apparatus. The cam has a locking-action cam-profile surface portion and an unlocking-action cam-profile surface portion, whereas the toothed block has a locking-action cam-contour surface portion and an unlocking-action cam-contour surface respectively brought into cam-connection with the locking-action cam-profile surface portion and the unlocking-action cam-profile surface portion. In the locked state, the relative distance between the unlocking-action cam-profile surface portion and the unlocking-action cam-contour surface portion included in the inside reclining device is shorter than the relative distance between the unlocking-action cam-profile surface portion and the unlocking-action cam-contour surface portion included in the outside reclining device, for providing a mechanical phase-lead of the inside reclining device with respect to the outside reclining device.
