Abstract
An assembly embedded into a headrest bun for permitting rotation of the bun between upright design and forward dump positions. The assembly includes a pair of tubes extending upwardly from a seatback frame and a fixed pivot rod extending between the tubes. A housing defines a package containing interior and including a pair of front and rear covers assembleable around the fixed pivot rod. A block shaped cam wedge is displaceably supported within the interior and biased in a first direction in seating fashion against an abutting location of the fixed rod. An actuating mechanism elevates the cam wedge to unseat from the pivot rod, the housing subsequently rotating from the design position to the forward dump position.
