Abstract
The present invention is an improvement in a door hinge construction for use on automotive vehicles for preventing the door from closing when the vehicle is parked on a sloping surface or from wind forces which act to close the door. A torsion bar is mounted in the stationary portion of the hinge and has a straight end portion which biases against a pair of rollers mounted on the movable portion of the hinge attached to the door to apply a torque to the movable hinge portion to maintain the door in the open position, with this torque increasing with wider opening of the door. The use of the rollers present a sliding contact with the torsion bar, thus eliminating unpleasant clicking noises during door opening and closing operations.
