An assembly to pivotally connect an external vehicle closure panel to a vehicle body includes a first hinge member that is constructed to be mounted to one of the external vehicle closure panel and the vehicle body, a second hinge member that is constructed to be mounted to the other of the external vehicle closure panel and the vehicle body, a shaft that is constructed to pivotally connect the first hinge member to the second hinge member, and a viscous rotary damper. The damper includes a cover, a rotor, and a viscous material. The shaft connects to the rotor such that rotation of the external vehicle closure panel between a closing position and an opening position causes relative motion between the rotor and the cover of the viscous damper to provide a resistance for controlling the velocity of the external vehicle closure member.

Hinge with a viscous rotary damper

A motion assist hinge mechanism includes a first and second hinge part mounted to the tailgate and vehicle body, respectively. The first hinge part includes a first cam having a sloped engagement surface engaged with a sloped engagement surface of a second cam of the second hinge part, under the bias of a resilient member, for moving axially along a pivot axis. The second cam is fixed to the vehicle body against pivotal movement relative to the pivot axis. When the tailgate is moved from a lowered, open position towards a raised, closed position, the resilient member translates a torque assisting force to the tailgate. The surface of the second cam may also include a detent that mates with the surface of the first cam to lock the tailgate at an angle.
