More Information
Summary:A disc recliner mechanism for use in an automotive vehicle includes a plurality of pawls and a cam mounted between a guide plate and a tooth plate. Rotation of the cam moves the pawls between an extended position in which the pawls engage the tooth plate to lock the disc recliner mechanism and a retracted position in which the pawls disengage the tooth plate to unlock the disc recliner mechanism and allow rotation between the guide plate and the tooth plate. A notch is disposed on an engagement surface of a cam lobe disposed on the cam for reducing friction when the cam lobe engages a cam follower disposed on the pawls. The tooth plate includes a circumferential outer lip with a concentric channel for retaining lubricant and reducing rotational friction between the tooth plate and the guide plate.
