Abstract
A seat assembly with an irreversible pawl adjusting latch mechanism in which a pawl with a plurality of teeth for insertion into apertures in a latch plate is provided with a portion of the teeth having edge surfaces inclined relative to the latch plate apertures so that upon insertion a wedge fit of the teeth into the apertures is provided to eliminate backlash in the latch mechanism. The pawl also includes a locking tooth having edge surfaces parallel to the latch plate apertures which, upon contact with the edges of the latch plate apertures prevent disengagement of the pawl from the latch plate due to fore and art loading on the seat assembly.
