ABSTRACT:
A reclining angle adjustment device for use with a reclining seat includes a pair of lock mechanisms adapted to be disposed respectively on the outer and inner sides of the reclining seat. Each of the lock mechanisms is capable of rough adjustment of the angle of inclination of the second arm with respect to the first arm, and of fine adjustment of the angle of inclination. The reclining angle adjustment device also includes a pair of hook plates coupled respectively to release levers of the lock mechanisms, a connecting pipe extending between and attached to hook plates for transmitting motion between the release levers, and a connecting bar inserted through the connecting pipe and coupled to angularly movable shafts of the lock mechanisms for transmitting motion between the angularly movable shafts. The connecting bar includes ends having serrated inner peripheral surfaces defining recesses. The angularly movable shafts include ends having serrated outer peripheral surfaces meshing with the serrated inner peripheral surfaces of the connecting bar. The hook plates have holes defined therein in alignment with the connecting pipe and having an inside diameter smaller than the outside diameter of the ends of the connecting bar.
