Glider Seating Unit with Selectively Powered Gliding Motion

原文（中文）

A glider seating unit with a selectively powered gliding motion is provided. The glider seating unit includes a base frame and a glide assembly movably connected to the base frame. The glide assembly is configured to glide in a forward direction and in a backward direction relative to the base frame. A glider drive mechanism is connected to the base frame and includes a motor, a drive shaft connected to the motor, a crankshaft releasably connected to the drive shaft at a joint, and a linkage connected between the crankshaft and the glide assembly. Operation of the motor in a first rotational direction connects the drive shaft to the crankshaft to rotate the crankshaft to thereby induce reciprocating forward and backward gliding motion of the glide assembly relative to the base frame. Operation of the motor of the glider drive mechanism in an opposite, second rotational direction disconnects the drive shaft from the crankshaft to permit the glide assembly to glide freely forward and backward relative to the base.
