Abstract
A seat assembly includes a hinge assembly having a linear adjustment mechanism including a recliner rod slidably supported by a housing and a pawl rotatably supported by the housing. The recliner rod preferably has a toothed portion that interfaces with a toothed portion of the pawl to prohibit the recliner rod from sliding. The pawl is pivotable relative the housing such that it may be disengaged to enable the recliner rod to slide freely. When the pawl engages the recliner rod in a locked position, a first force component generally normal to the engagement of the pawl and the recliner rod and a second force component generally through the pawl pivot reduce play and improve the load-carrying capacity of the linear adjustment mechanism.
