Abstract
A damped hinge module is disclosed and includes a first member, a second member and a torsion spring. The second member is rotationally movable relative to the first member between a first position and a second position. The second member being received at least in part within the first member. The torsion spring is located internally with respect to the first member and biases the second member toward the first position relative to the first member. The spring has a preload with the second member in the first position relative to the first member.
