Claim Text:
1. A damped hinge assembly for mounting a first member for pivotal movement relative to a second member about a hinge axis of rotation over a range of pivotal movement, the assembly comprising a linear piston and cylinder damper including a piston rod acting within a cylinder, means for mounting the linear piston and cylinder damper with a longitudinal axis parallel to the hinge axis, and camming means for converting pivotal movement of the first member in at least one direction of rotation into relative axial displacement between the piston rod and the cylinder of the linear piston and cylinder damper and for producing a varying amount of relative axial displacement between the piston rod and the cylinder of the linear piston and cylinder damper per degree of pivotal movement of the first member to cause the linear piston and cylinder damper to produce a damped resistive force to counter said pivotal movement of the first member over at least part of the range of pivotal movement, wherein the longitudinal axis of the linear piston and cylinder damper is arranged to be coincident with the hinge axis, wherein the camming means comprises a cam adapted to be indirectly mounted to one of the first and second members and a cam follower adapted to be indirectly mounted to another of the first and second members, wherein the cam comprises a pair of diametrically opposed camming surfaces, and wherein the cam follower comprises a pair of diametrically opposed nibs, with each nib engaging a respective camming surface.
