BACKGROUND

The present disclosure relates to occupant supports, and particularly to movable occupant supports. More particularly, the present disclosure relates to occupant supports with reclining seat backs for use in vehicles.

SUMMARY

According to the present disclosure, an occupant support includes a seat bottom, a seat back, and seat-motion controller. The seat back is coupled to the seat bottom for movement about a seat-back pivot axis relative to seat bottom. The seat-motion controller is configured to control movement of seat back about seat-back pivot axis relative to seat bottom.

In illustrative embodiments, the seat-motion controller includes a dual-recliner actuator that interconnects right and left recliners. The dual-recliner actuator provides means for changing the right and left recliners from a locked arrangement to an unlocked arrangement to allow pivotable movement of the seat back about the seat-back pivot axis. The dual-recliner actuator also provides means for changing the right and left recliners between the locked arrangement and the unlocked arrangement so that neither recliner blocks the other from reaching the locked arrangement.

In illustrative embodiments, the dual-recliner actuator includes a connector tube, an actuator lever coupled to the connector tube, a pair of lost-motion inserts, and a lever return spring. The connector tube interconnects the left recliner and the right recliner. The actuator lever is configured to move the connector tube from a locked position to a freed position to unlock right and left recliner locks and allow movement of the seat back about the seat back pivot axis. The actuator lever is biased by a torsion spring toward the locked position to maintain each recliner lock in the locked arrangement until the actuator lever is actuated as well as to neutralize an actuator lever inertial unlocking.

A left lost-motion insert is coupled to a left shaft and is moveable relative to the connector tube about the seat-back pivot axis. A right lost-motion insert is coupled to a right shaft and movable relative to the connector tube and the right lost-motion insert about the seat-back pivot axis. The left and right lost-motion inserts are configured to provide a lost-motion driving connection between the right recliner lock and the left recliner-lock to control unlocking and relocking of each recliner lock.

Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
