Abstract
A hinge assembly for use with a pivotally movable closure panel is operable to provide a counterbalancing force to lock or hold the closure panel in an open configuration against a predetermined threshold closure force without the need of separate support components such as gas-charged struts or prop rod. The hinge assembly is provided with upper and lower hinge arms which are pivotally connected towards their rearward ends for movement relative to each other for pivotal movement about a hinge pivot axis. A generally elongated or guide slot is formed in the lower hinge arm. A prop arm is pivotally secured at a first end to a forward portion of the upper hinge arm forwardly from the hinge pivot axis. A sliding member is secured toward the second other end of the prop arm and engages the guide slot so as to be reciprocally movable therealong as the hinge arms are moved between a fully closed and fully open positions. The guide slot includes an operational section and an engaged section. A resilient biasing member is used to engage and bias the sliding member forwardly relative to the guide slot as it moves through the engaged section while disengaging from or passively engaging the s…
