Abstract

A vehicle seat assembly includes a seat bottom and a seat back connected to the seat bottom. A reclining mechanism is configured to adjustably position the seat back. A head restraint assembly includes a head restraint and one or more supports pivotally connected to and cooperating with the seat back to position the head restraint adjacent an occupant's head. A headrest adjustment mechanism includes a spring connected to the one or more supports that biases the shaft from an unlocked toward a locked position and a release mechanism cooperating with the one or more supports which allows the one or more supports to be unlocked so that the headrest can be adjusted relative to the seat back.
