A recliner mechanism for a vehicle seat includes a toothed sector member
secured to a seat frame and first and second pivoted pawl members each
including a plurality of teeth to engage the teeth of the sector member.
The first and second pawl members also each pivot on a cam pin member
located at a distal end thereof, the cam pins each have a center axis and
an offset axis having by a toothed cam lobe. The toothed cam lobes mesh
such that rotation of one cam pin member causes the other cam pin member
to totate in the opposite direction. A handle is coupled to at least one
of the cam pin members to rotate the cam pin members and cause the pawl
members to rotate about a pin connecting the proximal ends of the pawl
members. The pawl members are movable between a first or locked position
and a second or unlocked position, permitting the seat back to be
adjusted with respect to the seat base against the force of a spring.
