Abstract
Disclosed herein is a continuously operable seat-reclining device having an improved actuator to substantially carry out a reclining operation of the reclining device such that an actuating force of a shaft is uniformly transmitted to the entirety of a coupling. The continuously operable seat-reclining device basically comprises an upper teeth bracket and a lower teeth bracket securely fixed to a seat back frame and a cushion frame, respectively, the upper teeth bracket being provided with upper teeth, the lower teeth bracket being provided with lower teeth, the upper teeth of the upper teeth bracket being engaged with the lower teeth of the lower teeth bracket, a cam hole formed at the center of the lower teeth bracket, and an actuator disposed between the cam hole and the cam-maintaining ring for moving the upper teeth bracket relative to the lower teeth bracket.
