Abstract
A car door hinge comprises a rotating member 2 hinged on a fixed member I by means of a hinge pin 3. One end 5 of a wire spring 4 is attached to a point on the rotating member 2 distant from the hinge pin, and the other end 8 of the wire spring 4 is attached to a point on the fixed member 1 inside a sector of a circle defined by the hinge pin 3 and an arc subtended at the hinge pin 3 which is described by the end 5 as the rotating member rotates. A spring restoring force therefore acts during the opening and closing of the door so that the door always opens and closes properly. Moreover, the spring occupies a minimum of space, and the rotation of the door is stopped at a predetermined angle.
