Abstract
A dynamic head restraint mount (18) includes an low swinging impact plate (22) which swings back below a seat back frame top tube (10) in response to a sudden vehicle deceleration. As it swings back, the plate (22) causes the upper ends of a pair of upstanding head restraint support post guide tubes (24) to rock forwardly of the top tube (10), tilting the head restraint 14 forward. Concurrently, a linkage activated by the same impact plate (22) motion independently causes the support posts (12) of the head restraint (14) to slide up to a consistent highest position above the top tube (10), regardless of the adjusted position within the guide tubes (24) from which the support posts (12) began.
