TELESCOPING HEAD RESTRAINT

A headrest assembly includes a headrest bun adjustably supported on a linkage system. An adjustable cover assembly is operable between stowed and deployed positons relative to a position of the headrest bun and is configured to cover the linkage system in use. The adjustable cover assembly includes first and second members, wherein the first member is coupled to the linkage system for movement therewith and the second member is pivotally coupled to the first member. A gap is defined between the first member and the second member, and the gap is maintained by a plurality of spacers disposed on the first member as the cover assembly moves from the stowed position to the deployed position with the headrest bun.
