ABSTRACT:
An apparatus for massaging mountable behind the back of a chair and capable of being moved vertically to provide relaxing massage to a user sitting on the chain. A reversible motor mechanism provides the rotational motion to a clutch assembly that selectively engages one of two gear assemblies that in turn activate two different linkage and reciprocating mechanisms that simulate or follow the movements of the fingers of a conventional masseur.
