Claim:
A head restraint system for a vehicle seat comprising: a pair of rods adapted to be fixed relative to a vehicle seat, each of the pair of rods provided with a series on indents formed therealong; a frame mounted to distal ends of the pair of rods; a head restraint mounted to the frame for axial translation along the pair of rods; and a locking mechanism for locking the head restraint at a plurality of locations along the pair of rods; wherein the locking mechanism comprises a pair of plates, each fixed for translation in the frame and each plate is sized to be received within the indents of one of the rods for locking the head restraint relative to the pair of rods, a first biasing member and a second biasing member, each for biasing one of the plates into engagement with one of the plurality of rod indents in absence of a manually applied force; wherein the first plate further comprises a tab oriented laterally outboard relative to the frame for access by the occupant for manual actuation of the plate to an unlocked orientation; and wherein the second plate further comprises a tab, with the second biasing member extending between the two tabs of the two plates such that when the occupant actuates the first plate to an unlocked orientation, the first plate actuates the second biasing member, which consequently actuates the second plate to an unlocked position.
