Claims20
A recliner mechanism comprising:
- a first plate having a ring groove, a set of pawl slots disposed proximate the ring groove, and a set of pawl tooth openings that extend between the ring groove and an outer surface of the first plate, wherein each pawl tooth opening is disposed between first and second spacer teeth of the first plate that extend between the ring groove and the outer surface;
- a second plate configured to rotate with respect to the first plate, the second plate having a set of teeth that are received in the ring groove;
- and
- a set of pawls, wherein each member of the set of pawls is received in a member of the set of pawl slots;
- wherein a first member of the set of pawls extends between members of the set of teeth and into a first pawl tooth opening, and a second member of the set of pawls extends between members of the set of teeth but not into a member of the set of pawl tooth openings to inhibit rotation of the second plate with respect to the first plate.

A recliner mechanism comprising:
- a first plate having a center hole, a ring groove, a set of pawl slots that intersect the ring groove, and a set of pawl tooth openings that extend outwardly from the ring groove to an outer surface of the first plate that is disposed opposite the center hole, wherein each pawl tooth opening is disposed between first and second spacer teeth of the first plate that are disposed between the ring groove and the outer surface;
- a second plate configured to rotate with respect to the first plate, the second plate having a set of teeth that are received in the ring groove;
- and
- a set of pawls, wherein each member of the set of pawls is received in a member of the set of pawl slots and has a master pin and a slave pin having a different configuration than the master pin;
- wherein the master and slave pins of a first member of the set of pawls extend between members of the set of teeth and into different members of the set of pawl tooth openings to inhibit rotation of the second plate with respect to the first plate.
2 more elements
A recliner mechanism comprising:
- a first plate having an outer surface that extends around an axis, a ring groove that is spaced apart from the outer surface, a set of pawl slots disposed adjacent to the ring groove, and a set of pawl tooth openings, wherein each member of the set of pawl tooth openings is defined by a first spacer tooth and a second spacer tooth that extends from the ring groove to the outer surface and is disposed on an opposite side of the ring groove from the set of pawl slots;
- a second plate configured to rotate about the axis with respect to the first plate, the second plate having a set of teeth that are received in the ring groove;
- and
- a set of pawls, wherein each member of the set of pawls is received in a member of the set of pawl slots;
- wherein only a first member of the set of pawls extends between members of the set of teeth and into a member of the set of pawl tooth openings to inhibit rotation of the second plate with respect to the first plate.
