Abstract
A torsion bar hood lift assist includes a torsion bar mounted with a free end portion positioned to engage and travel along a hood interior surface as the hood of the vehicle is opened and closed. As the hood is closed, the torsion bar bends and twists to store energy which is then transferred to the hood to assist in hood opening when the hood is lifted. The free end portion of the torsion bar supports a hood engagement member such as a roller to reduce friction between the torsion bar and hood as energy is transferred. The torsion bar is typically supported at two locations with a bearing block being used to further reduce friction. The free end of the torsion bar engages a hood reinforcing member or plate, which may comprise a hood mounting bracket, and travels against this plate during hood opening and closing.
