Abstract
A reclining device comprises a base fixedly connected to a seat cushion and an arm fixedly connected to a seat back and rotatably supported on the base. The arm has at least one inner toothed portion. A toothed block is slidably disposed between the base and the arm and has an outer toothed portion on an outer periphery thereof and a cam-contour surface on an inner periphery thereof. The base is formed integral with a recessed guide defining therein two parallel diametrically-opposed side walls for slidably guiding the toothed block outward, away from a center of rotation of the arm and inward toward the center of rotation of the arm. A rotary cam has a cam-profile surface on an outer periphery thereof. The cam-profile surface is in cam-connection with the cam-contour surface of the toothed block for producing an outward sliding motion of the toothed block to mesh the outer toothed portion with the inner toothed portion by a rotary motion of the cam in a first rotational direction and for producing an inward sliding motion of the toothed block to unmesh the outer toothed portion from the inner toothed portion by a rotary motion of the cam in a second rotational direction opposing the first rotational direction. An operating lever is mechanically linked to the cam for producing rotary motion of the cam. The two parallel side walls of the recessed guide are formed to guide the toothed block in a direction offset from a direction of a center line of the outer toothed portion of the toothed block by a predetermined angle.
