Abstract: A bezel-less actuator button is disposed on a seat assembly and is operable between at-rest and actuated positions. The actuator button is coupled to a trim cover that covers a cushion member of the vehicle seat. The actuator button includes a head member and a shaft portion extending outwardly from the head member through a receiving well disposed in the cushion member and opening into a seat interior. A portion of the trim cover is coupled to a receiving channel defined between the head member of the actuator button and a plate member disposed on the shaft portion of the actuator button. The actuator button is retained in place by the trim cover and the cushion member without the need for a separate bezel assembly.

Abstract: A motor vehicle comprises an upper back support comprising a substantially U-shaped tubular member pivotally attached at a first end to one of a pair of opposed lateral seatback frame members and pivotally attached at a second end to the other of the pair of opposed lateral seatback frame members, a substantially rigid planar base attached to a central portion of the tubular member, a latch operably coupling the first end of the tubular member to the one of a pair of opposed lateral seatback members to restrain the tubular member in one of a plurality of positions between a stowed position and a fully raised position, and a cushion disposed above the upper back support to form a movable exposed surface.
