A hinge and linkage system comprises a four-link system wherein first and second links are respectively connected to vehicle body and closure members, and an additional pair of links interconnect the first and second links. An expansible gas strut also interconnects the first and second links. In accordance with the invention, an expansible spring-biased plunger mechanism is mounted upon one of the additional links so as to operatively engage and be axially compressed by the second link and the closure member when the closure member is disposed at its latched position. When the closure member is unlatched, the spring-biased plunger mechanism initially partially elevates the closure member toward its open position whereupon the expansible gas strut can continue the elevational movement of the closure toward its open position.

1. A hinge and linkage system for permitting pivotal movement of a latchable closure member with respect to a body member and for assisting the lifting of the closure member with respect to the body member, comprising:a first hinge part adapted to be attached to the body member; a second hinge part adapted to be attached to the closure member; a plurality of linkage members hingedly interconnecting said first hinge part to said second hinge part; and a spring-biased plunger mechanism fixedly mounted upon one of said plurality of linkage members and operatively disengageably engageable with said second hinge part which is adapted to be attached to the latchable closure member such that when the latchable closure member is disposed in its latched position, said first and second hinge parts are disposed in close proximity with respect to each other such that said spring-biased plunger mechanism is operatively engaged with said second hinge part and thereby axially compressed, whereas when the latchable closure member is unlatched, said spring-biased plunger mechanism undergoes axial expansion so as to cause said second hinge part and the closure member to which said second hinge part is attached to undergo partial elevational movement with respect to the body member, whereupon continued elevational movement of the closure member with respect to the body member, said spring-biased plunger mechanism will be operatively disengaged from said second hinge part.
