1. 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 and having a plurality of teeth extending radially inward therefrom, the outer lip having an axial outer surface axially facing and rotatably engaging 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; and
wherein the outer lip of the tooth plate includes a channel recessed in the axial outer surface for retaining lubricant and reducing rotational friction between the tooth plate and the guide plate.
