Abstract
A rotary magnetic damper comprises a first, rotary damper element, a second, static damper element and a rotary input coupled to the rotary damper element. The coupling between the input and the rotary damper element is such that rotation of the rotary input causes the rotary damper element to progressively magnetically engage the static damper element whereby to progressively increase a damping force created by the damper. The rotary damper element may be a magnet or magnets mounted on a carrier which threadingly engages a screw driving element such that as the input rotates the carrier, it and the rotary damper element translate axially along the screw driving element towards the static damper element.
