ABSTRACT:
A power actuated mechanical backrest apparatus is disclosed. This device is provided to cooperatively interact with the musculature of the human back for the purpose of providing massage action. The device consists of a rigid frame including a movable spindle. The device functions using a movable spindle and a variety of gears to cause various plungers to ride against undulating forms causing the plungers to undulate against the user's back and thereby provide a mechanical massage action. The backrest is overlaid with a cushion material that may be provided with a heating member. The device is small, portable and lightweight.
