Abstract
An energy absorption assembly for a seat assembly having a seatback including a first frame and a second frame includes a housing, a torsion bar rotatably supported by the housing in a first rotational direction and in a second rotational direction, and a clutch assembly engaged with the torsion bar. Engagement between the clutch assembly and the torsion bar permits rotation of the torsion bar relative to the housing in one of the first direction and the second direction to permit movement of the second frame relative to the first frame and restricts rotation of the torsion bar relative to the housing in the other of the first direction and the second direction to restrict movement of the second frame relative to the first frame. Restricting rotation of the torsion bar relative to the housing absorbs energy associated with movement of the second frame relative to the first frame.
