- a seat;
a seat back positionably secured to the seat, the seat back having an upper face and a seat face, the seat face defining a contour adapted to contact and support the back of a person sitting in the seat assembly;
a head restraint separate from and positionably secured to the seat back via a generally vertically oriented support member, wherein the head restraint is positionable between a raised position and a lowered position relative to the upper face of the seat back and is positionable between a forward position and a rearward position relative to the upper face of the seat back; and
an adjusting system operably associated with the seat back and the head restraint, wherein while maintaining the same upright orientation of the seat back relative to the seat, the adjusting system is configured such that upon a change in the height position of the head restraint relative to the upper face of the seat back and upon a change in the forward or rearward position of the head restraint relative to the upper face of the seat back, the contour of the seat face of the seat back changes.

Abstract
A vehicle seat and head restraint assembly is disclosed in which the configuration of the seat back is automatically adjusted as the position of the head rest is changed. Upon lowering the head restraint, a forwardly directed face of the seat back is urged outward to thereby decrease a torso angle associate with the seat assembly. Additional versions are described in which the torso angle is decreased by raising the head rest. And, versions are described in which horizontal or pivotal movement of the head restraint causes movement of a forward face of the seat back.
