Abstract
An infinitely adjustable linear locking assembly for vehicle seats is disclosed which includes a movable elongated element defining a longitudinal axis. First and second roller ball assemblies coaxial with the elongated element are provided, which assemblies have at least two substantially equidistantly spaced apart roller balls surrounding the elongated element. First and second roller ball housings contain the first and second roller ball assemblies, respectively. The housings are coaxial with the elongated element and have internal wedging surfaces for wedging the roller balls between the internal wedging surfaces and the elongated element. A rotatable locking member is provided adjacent to each roller ball assembly, with the locking member being coaxial with the moveable element and rotatable about the elongated element. Each locking member has a cam for urging each roller ball in an adjacent roller ball assembly into wedging relationship between the internal wedging surface and the elongated element upon rotation of the locking member in a first direction, and for releasing the wedging relationship upon rotation of the locking member in a second direction which is reverse to t…
