A back support mechanism for a vehicle seat is provided with a track mounted to a seat back of the vehicle seat. A carriage is mounted to the track for linear translation along the track between a first position and an actuated position. A support member is connected to the carriage for supporting a back portion of an occupant of the vehicle seat. A biasing member cooperates with the carriage to urge the carriage to the first position. If the occupant back portion imparts a load to the support member exceeding a predetermined force, the support member and the carriage translate along the track over a range of translation. The range of translation is sized to accommodate a corresponding translation of a head of the occupant to a head restraint of the vehicle seat.
