1. An adjustment mechanism comprising:
- a housing;
a pawl rotatably supported by said housing;
a sector plate rotatably supported by said housing and ratcheting along said pawl in a first rotational direction and operable to selectively lock said sector plate in one of a plurality of angular positions and to prevent rotation of said sector plate in a second rotational direction relative to said housing; and
a reset lever in selective engagement with said pawl to rotate said pawl out of engagement with said sector plate to permit rotation of said sector plate in said second rotational direction.

Abstract
An adjustment mechanism includes a housing, a pawl rotatably supported by the housing, and a sector plate rotatably supported by the housing. The sector plate ratchets along the pawl in a first rotational direction and selectively locks the sector plate in one of a plurality of angular positions to prevent rotation of the sector plate in a second rotational direction relative to the housing. A reset lever is in selective engagement with the pawl to rotate the pawl out of engagement with the sector plate and permit rotation of the sector plate in the second rotational direction.
