Claim 37:
38. 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 rotatably engaging the guide plate and having a plurality of teeth extending radially inward therefrom, wherein the outer lip of the tooth plate includes a channel for retaining lubricant and reducing rotational friction between the tooth plate and the guide plate;
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; and
a cam rotatably mounted between the guide plate and the tooth plate, the cam including a radially outer cam profile 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;
at least one cam lobe disposed on the radially outer cam profile and at least one cam follower disposed on the radially inner cam surface, wherein the cam lobe includes an engagement surface for selectively engaging the radially inner cam surface of the pawl; 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.
