Still another object of the present invention is to provide a seat recliner mechanism wherein the bushings which pivotally connect the first and second and third and fourth plates are each provided with an annular collar the radial face of which are in bearing engagement with the radial face of a collar formed on each of the first and second rotary connecting shafts. Another important object of the present invention is to provide a rotary seat recliner mechanism that is inexpensive to manufacture utilizing automatic high volume manufacturing techniques. The seat recliner mechanism 10 is provided with a first plate 14 which is formed and contoured to abut the seat back frame for attachment thereto. The control pin 26 is fixedly attached to the locking pawl 24 by suitable fastening means. The ratchet is supported so that it can be turned and has a radial slot which engages a pin fixed to the seat for locking the back rest into position. It is, accordingly, a further object of the present invention to provide a seat recliner mechanism to carry out the operations and functions described in the foregoing. No. A release handle is pivotally connected at the pivot point to the first and second plates having a camming slot therein for receiving and camming the pin. 2,328,908 and 2,414,910 are also typical of the above class of seat recliner mechanisms. Onetouch The selection of materials of the various components as well as the finishing and hardening thereof will be all as determined by good engineering practices. Also we can yield orders conform to the requirements of standards,and provide relevant certifications and test reports to you. As each of the pins 26 and 74 move within the slots 40 and 86 the locking pawls 24 and 72 to which they are attached will move away from the first and third plates 14 and 60 to disengage their respective teeth portions 42 and 88 thereby allowing the first plate 14 to move freely with respect to the second plate 16 and, similarly, the third plate 60 freely with respect to the fourth plate 62 both of which are acting against the torsion bars 44 and 90. - Second spring means bias the release handle toward the second plate to mesh the series of teeth on the pawl with the teeth on the first plate to lock the first plate with respect to the second plate.
