Claim 19:
20. A disc recliner mechanism for use in an automotive vehicle, the disc recliner mechanism comprising:
a guide plate;
a tooth plate with an outer lip extending circumferentially therearound, the outer lip having a plurality of teeth extending radially inward therefrom;
at least one pawl mounted between the guide plate and tooth plate, the pawl including a toothed outer edge and a radially inner cam surface with at least one cam follower; and
a cam rotatably mounted between the guide plate and the tooth plate, the cam including a radially outer cam profile with at least one cam lobe, the cam lobe having an engagement surface for selectively engaging the radially inner cam surface of the pawl, wherein rotation of the cam moves the pawl between an extended position in which the pawl engages the tooth plate to lock the disc recliner mechanism, and a retracted position in which the pawl disengages the tooth plate to unlock the disc recliner mechanism; and
wherein the engagement surface of the cam lobe includes a notch to create a gap between the cam lobe and the cam follower for reducing friction therebetween when the cam lobe selectively engages the cam follower.
