TELESCOPING POWER HEAD RESTRAINT WITH COVER ASSEMBLY

A headrest assembly includes a linkage system that is at least partially disposed within a housing. The linkage system is operable between fore and aft positions relative to the housing. An adjustable cover assembly includes a first member coupled to the linkage system for movement therewith, and a second member pivotally coupled to the first member. The second member includes an engagement flange configured to contact a portion of the housing to pivot the second member rearwardly as the adjustable cover assembly is driven outward by the linkage system during the positioning of a headrest bun.
