Abstract
A disc recliner mechanism includes travel stops to limit angular movement of a seat back through a defined range. At least one pawl on a guide plate of the disc recliner mechanism includes a guide boss with a pair of opposite stop surfaces that contact a respective travel stop formed on a tooth plate of the disc recliner mechanism to limit the range of rotational movement of the tooth plate. The guide boss includes a guide surface which engages a guideway on the tooth plate to provide a free movement range wherein the tooth plate can be rotated through the free movement range without requiring the operation of a release mechanism. The guideways on the tooth plate and the guide bosses on the pawls are designed such that the tooth plate and pawls can be formed with simple stamping operations.
