This disclosure relates to a hinge assembly for mounting a closure member or tailgate to a vehicle. It includes a hinge bracket and connector body for connection to one side of the tailgate. The connector body provides a fixed connection to the vehicle and enables the hinge bracket to rotate about a pivot axis, so that the tailgate rotates. Also included are a first torque rod having one end fixed to the connector body and an opposite, free end, and a second torque rod spaced from the first torque rod and pivot axis. The second torque rod has one end fixed to the hinge bracket and an opposite, free end. A connector device anchors the free ends of the torque rods together within the tailgate, so that the rods deflect when the tailgate is pivoted between its opened and closed positions to produce a biasing torque towards an opposite position.

1. A hinge assembly for mounting a closure member between spaced apart body side panels of a vehicle body for movement about a pivot axis between at least open and closed positions comprising: a hinge bracket constructed for connection to one side of the closure member;a connector body constructed for connection at the one side of the closure member and for connecting to the hinge bracket, the connector body configured for establishing a fixed connection to the vehicle body and enabling the hinge bracket to rotate about the pivot axis;a first torque rod having one end fixed to the connector body and an opposite, free end;a second torque rod spaced from the first torque rod and pivot axis, the second torque rod having one end fixed to the hinge bracket and an opposite, free end; anda connector device constructed to anchor the opposite, free ends of the first and second torque rods together within the closure member;wherein the torque rods are configured to deflect when the closure member is pivoted between the at least open and closed positions to produce a biasing torque towards an opposite position. 2. The hinge assembly according to claim 1, wherein the first torque rod is constructed for securement to the connector body. 3. The hinge assembly according to claim 2, wherein the second torque rod is constructed to be fixedly attached to a mounting block, the mounting block configured for securement to the hinge bracket such that it substantially prevents the second torque rod from rotating relative to the hinge bracket. 4. The hinge assembly according to claim 3, further comprising a hinge pin, the hinge pin configured to connect the connector body and one of the side panels of the vehicle body. 5. The hinge assembly according to claim 1, further comprising a second connector body for connection at the other side of the closure member, the second connector body configured for alignment on and rotation about the pivot axis and for connection to a second of the side panels of the vehicle body. 6. The hinge assembly according to claim 1, wherein the connector device anchoring the opposite, free ends of the first and second torque rods comprises shock absorbing material. 7. The hinge assembly according to claim 6, wherein the shock absorbing material is provided around the connector device. 8. The hinge assembly according to claim 7, wherein the shock absorbing material is rubber. 9. The hinge assembly according to claim 1, wherein at least one of the ends of each of the first and second torque rods comprises a “D” shaped portion. 10. The hinge assembly according to claim 9, wherein the opposite, free ends of each of the first and second torque rods comprises “D” shaped portions. 11. The hinge assembly according to claim 10, wherein the connector device comprises complimentary slots for receiving the “D” shaped portions of the first and second torque rods. 12. The hinge assembly according to claim 1, wherein the connector device comprises complimentary slots for receiving the first and second torque rods therein. 13. The hinge assembly according to claim 1, wherein the connector device is configured for movement between at least a first position and a second position on the opposite, free ends of the first and second torque rods. 14. A vehicle door comprising: a hinge assembly for mounting a closure member between spaced apart body side panels of a vehicle body for movement about a pivot axis between at least open and closed positions comprising: a hinge bracket constructed for connection to one side of the closure member;a connector body constructed for connection at the one side of the closure member and for connecting to the hinge bracket, the connector body configured for establishing a fixed connection to the vehicle body and enabling the hinge bracket to rotate about the pivot axis;a first torque rod having one end fixed to the connector body and an opposite, free end;a second torque rod spaced from the first torque rod and pivot axis, the second torque rod having one end fixed to the hinge bracket and an opposite, free end; anda connector device constructed to anchor the opposite, free ends of the first and second torque rods together within the closure member;wherein the torque rods are configured to deflect when the closure member is pivoted between the at least open and closed positions to produce a biasing torque towards an opposite position. 15. The vehicle door claim 14, wherein the vehicle door is a tailgate. 16. A vehicle comprising: a body having an opening;a closure member for closing the opening, the closure member being pivotally mounted to the body at the opening for movement about a generally horizontal pivot axis between a raised position and a lowered position;a pair of hinge mechanisms on opposing sides of the closure member, the hinge mechanisms pivotally mounting the closure member for the movement about the pivot axis;wherein one of the pair of hinge mechanisms comprises: a hinge assembly for mounting a closure member between spaced apart body side panels of a vehicle body for movement about a pivot axis between at least open and closed positions comprising:a hinge bracket constructed for connection to one side of the closure member;a connector body constructed for connection at the one side of the closure member and for connecting to the hinge bracket, the connector body configured for establishing a fixed connection to the vehicle body and enabling the hinge bracket to rotate about the pivot axis;a first torque rod having one end fixed to the connector body and an opposite, free end;a second torque rod spaced from the first torque rod and pivot axis, the second torque rod having one end fixed to the hinge bracket and an opposite, free end; anda connector device constructed to anchor the opposite, free ends of the first and second torque rods together within the closure member;wherein the torque rods are configured to deflect when the closure member is pivoted between the at least open and closed positions to produce a biasing torque towards an opposite position. 17. The vehicle according to claim 16, wherein the closure member is a tailgate. 18. A method for assembling a hinge assembly for mounting a closure member between spaced apart body side panels of a vehicle body for movement about a pivot axis between at least open and closed positions, the method comprising: connecting a first end of a first torque rod to a connector body constructed for connection at the one side of the closure member and for connecting to a hinge bracket, the connector body configured for establishing a fixed connection to the vehicle body and enabling the hinge bracket to rotate about the pivot axis, and the first torque rod having an opposite, free end;connecting a first end of a second torque rod to the hinge bracket, the hinge bracket constructed for connection to one side of the closure member, and the second torque rod having an opposite, free end and being spaced from the first torque rod and the pivot axis; andanchoring the opposite, free ends of the first torque rod and the second torque rod together via the connector device. 19. The method according to claim 18, further comprising providing shock absorbing material around the connector device. 20. The method according to claim 18, wherein the connector device is configured for movement between at least a first position and a second position on the opposite, free ends of the first and second torque rods, and wherein the method further comprises adjusting the connector device from between the first position and the second position on the opposite, free ends of the first and second torque rods before the anchoring of the connector device.
