Abstract: A mechanism for assisting the movement of a deck lid of a vehicle includes a transverse torsion bar centrally formed with a bight segment. A roller is rollably engaged with the bight segment, and the ends of the torsion bar are affixed to the body of the vehicle. A ratchet track is affixed to the deck lid, with the ratchet track including a plurality of longitudinally spaced detents for releasably receiving the roller therein as the deck lid is moved. The torsion bar assists a person in raising the deck lid, with the cooperation between the ratchet track and torsion bar tending to hold the deck lid in positions that are intermediate the fully open and fully closed positions when the person releases the deck lid.
