Abstract

See full text

A friction based counterbalance mechanism for coupling with a closure panel of a vehicle to assist in opening and closing of the closure panel, the counterbalance mechanism including: a first housing having a first pivot connection mount for connecting to one of a body of the vehicle and the closure panel; an extension member coupled to the first housing at one end and being extendable and retractable with respect to a second housing coupled adjacent to the first housing along an axis, the second housing for connecting by a second pivot connection mount to the other of the body and the closure panel; a sliding friction mechanism having: a shaped sleeve mounted on an exterior surface of the extension member, the shaped sleeve providing an exterior friction surface; and a resilient friction element mounted to the second housing in a fixed location on the axis, the resilient friction element positioned between second housing and the shaped sleeve and biased into contact with the exterior friction surface; wherein relative movement between the shaped sleeve and the resilient friction element as the extension member is displaced generates sliding friction between the resilient friction element and the shaped sleeve.
