Abstract
A damper ( ) for damping motion between two relatively moveable members, such as pivotal motion between components in office chairs ( ). The damper ( ) includes a outer member ( ) having an internal recess ( ) with a inner surface ( ) and a crosswise oriented hole ( ) intersecting the recess ( ), and an inner member assembly ( ) moveable relative to the outer member ( ) having a shaft ( ) with a resilient friction member ( ) mounted thereon. The resilient friction member ( ) frictionally engages the inner surface ( ) in an interference fit relationship thereby radially precompressing the resilient friction member ( ). The resilient friction member ( ) preferably has one or more protrusions ( ) that may be axially or radially oriented.
