A hinge assembly for a vehicle having an eNgine compartment with a hood opening and a hood for closing said opening, said hinge assembly including hinge members connected to said hood and said engine compartment, respectively, said members being pivotally connected to each other for swinging movement of said hood about a horizontal axis from a closed to an open position through an arc greater than 90 degrees, said compartment hinge member including cam means fixed relative to said axis, said hood hinge member pivoted on said axis and attached to said hood, a force-transmitting member pivoted relative to and mounted on said hood member at a point spaced from said axis and having guide means engaging said cam means, a tension spring supported on said hood member and exerting a substantially constant force for swinging said guide means into engagement with said cam means to counterbalance the weight of said hood and resulting in a net lifting force varying from a maximum value at opening to a substantially constant minimum after opening and to said fully open position.
