Abstract
Abstract The hinge for mounting a closure panel on a vehicle body includes a body bracket mounted on the vehicle body and having a cam surface and an elongated cam slot. A panel bracket is mounted on the closure panel and has a cam follower portion slidably bearing on the cam surface of the body bracket to define a first cam arrangement. A torsion bar has one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar torsionally biases the panel bracket and closure panel to a normal pivotal position relative the vehicle body. The portion of the torsion bar mounted on a panel bracket extends slidably through the cam slot of the body bracket to define a second cam arrangement. The first and second cam arrangements are arranged relative one another whereby upon pivotal opening movement of the closure panel, the closure panel is bodily shifted to avoid interference of the closure panel with the vehicle body.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
A hinge for mounting a closure panel on a body panel comprising: a body bracket mounted on the body panel; a panel bracket mounted on the closure panel; a torsion bar having one end attached to one of the panels and the other end attached to the bracket mounted on the other panel so that the torsion bar torsionally biases the closure panel to a normal position relative the body panel; first cam means acting between the body bracket and the panel bracket including a cam surface on one of the brackets and a cam follower on the other bracket; and a cam slot provided in the bracket mounted on the one panel having the one end of the torsion bar attached thereto, said torsion bar extending through the cam slot and coacting therewith to define a second cam means whereby upon pivotal movement of the closure panel the first and second cam means cooperate to bodily shift the closure panel to avoid interference of the closure panel with the body panel.
Claim 2
Dependent Claim
172 words
A hinge for mounting a closure panel on a body panel comprising: a body bracket mounted on the body panel; a panel bracket mounted on the closure panel; a torsion bar having one end attached to one of the panels and the other end attached to the bracket mounted on the other panel so that the torsion bar torsionally biases the closure panel to a normal position relative the body panel; first cam means acting between the body bracket and the panel bracket including a cam surface on one of the brackets and a cam follower on the other bracket; and a cam slot provided in the bracket mounted on the one panel having the one end of the torsion bar attached thereto, said torsion bar extending through the cam slot and coacting therewith to define a second cam means whereby upon pivotal movement of the closure panel the first and second cam means cooperate to bodily shift the closure panel to avoid interference of the closure panel with the body panel.
Claim 3
Dependent Claim
161 words
A hinge for mounting a closure panel on a vehicle body comprising: a body bracket mounted on the vehicle body and having a cam surface and an elongated cam slot; a panel bracket mounted on the closure panel and having a cam follower portion slidably bearing on the cam surface of the body bracket to define a first cam means; a torsion bar having one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar torsionally biases the panel bracket and closure panel to a normal pivotal position; and said torsion bar mounted on the panel bracket extending slidably through the cam slot of the body bracket to define a second cam means, said first and second cam means being arranged relative one another whereby upon opening movement of the closure panel the closure panel is bodily shifted to avoid interference of the closure panel with the body panel.
Claim 4
Dependent Claim
161 words
A hinge for mounting a closure panel on a vehicle body comprising: a body bracket mounted on the vehicle body and having a cam surface and an elongated cam slot; a panel bracket mounted on the closure panel and having a cam follower portion slidably bearing on the cam surface of the body bracket to define a first cam means; a torsion bar having one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar torsionally biases the panel bracket and closure panel to a normal pivotal position; and said torsion bar mounted on the panel bracket extending slidably through the cam slot of the body bracket to define a second cam means, said first and second cam means being arranged relative one another whereby upon opening movement of the closure panel the closure panel is bodily shifted to avoid interference of the closure panel with the body panel.
Claim 5
Dependent Claim
173 words
A hinge for mounting a closure panel for pivotal and bodily shifting movement between open and closed positions on a vehicle body comprising: a body bracket mounted on the vehicle body; a panel bracket mounted on the closure panel; a torsion bar having one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar biases the panel bracket and closure panel to the normal open or closed position; and a first cam means and a second cam means, each cam means acting between the body bracket and the panel bracket and adapted to effect bodily shifting movement of the panel bracket relative the body bracket during pivotal movement of the closure panel between the open position and the closed position, one of said cam means including an elongated cam slot in the body bracket and said torsion bar extending slidably through the cam slot for migration along the cam slot during pivotal movement of the panel bracket relative the body bracket.
