Abstract
A rotary-cam type reclining device comprises a base fixedly connected to a seat cushion, a toothed arm fixedly connected to a seat back and rotatably supported on the base via a pivot, a toothed block slidably disposed between the base and the arm and having an outer toothed portion and a cam-contour surface and slidably guided by two parallel side walls of a recessed toothed-block guide defined in the base, a rotary cam for producing outward and inward sliding motions of the toothed block to mesh and unmesh the outer toothed portion of the toothed block with and from the inner toothed portion of the arm by a rotary motion of the cam, and an operating lever mechanically linked to the cam for producing the rotary motion of the cam. Also provided between the arm and the toothed block is an auxiliary interlocking member, which is responsive to a deformation of the toothed block resulting from impact force applied to the arm for interlocking the device.
