Abstract:
A reclining device comprising:a plurality of pawls having first teeth; a ratchet having second teeth that mesh with the first teeth; a holder that holds the pawls such that the first teeth of the pawls can move selectively toward and away from the second teeth of the ratchet, wherein the ratchet is rotated concentrically with respect to the holder; a cam body that moves the pawls toward the ratchet and brings the pawls into mesh with the ratchet so as to prevent the holder and the ratchet from rotating relative to each other; and an unlock member that holds at least one of the pawls while the holder and the ratchet form a relative rotational angle within a predetermined range and that brings the at least one of the pawls out of mesh with the ratchet, wherein the cam body is urged to rotate for moving the pawls toward the ratchet, and when at least one of the pawls is disengaged from the ratchet by the unlock member, the pawl moves back causing the cam body to stop rotating against an urging force; and wherein the sum of the angles to be set to bring the pawls into mesh and the angles to be set to bring the pawls out of mesh exceeds 360Â°.
