Abstract
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.
