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.
Abstract:
A novel electromagnetic vibration generator, wherein a coil member capable of generating magnetic line of force and its magnetic counterpart are placed in parallel and united in one body in such a manner that the coil member and magnetic counterpart form a uniform gap, is disclosed. A coil member and a vibration plate are feasible as the magnetic counterpart. The vibration generator is driven by supplying an alternating current to the coil member so that a set of coil member successively attract or repel each other, or that the magnetomotive force of single coil member successively attracts the vibration plate. The vibration generator is vibrotherapeutically effective in the vibration frequency range of 50-80 times/sec, and 100-280 times/sec.
Abstract:
An air lumbar support device utilized in an automobile seat for adjusting the curvature of a seat back by selectively regulating air pressures of a plurality of air bags accommodated in the seat back. The support device includes a pressure sensor detecting the air pressures of the seat bags, an input circuit supplying an electric signal from the pressure sensor to a control circuit, an output circuit receiving electric signal from the control circuit and causing an air control valve to actuate to thereby control the air pressures of the air bags, and a memory circuit memorizing and reading the electric signal supplied from the input circuit to the control circuit.
Abstract:
A massaging apparatus comprises a pair of massaging wheels obliquely and eccentrically attached to a main shaft, a shifting mechanism for shifting the massaging wheels and main shaft in the direction of the length of a chair back rest or a bed, and a spacing changing mechanism for changing the spacing between the massaging wheels. The apparatus is designed to detect the position of the pair of massaging wheels and the spacing therebetween. It further comprises position selecting switches associated with the neck, shoulders, back and waist of the human body. When any one of these position selecting switches is operated, the shifting mechanism and the spacing changing mechanism as well as the rotative direction of the main shaft are automatically controlled in accordance with the detected shifted position and spacing of the massaging wheels.
Abstract:
The combination of a pressure-switch operated vibrating motor, enclosed within a cushioning material, such as synthetic or natural foam, having an enlarged surface area relative to that of the motor. As a person applies pressure on said enlarged cushioning means, as by leaning on the cushion, the pressure switch is engaged to close a circuit thereby starting the vibrating motor enclosed within the cushioning means. The cushioning means acts as a damping means for the vibrating motor for greater comfort than would otherwise occur if the vibrating motor were not so enclosed.
Abstract:
Nonrotating vibrator motors are mounted on a rigid member in furniture. Electric power at different frequencies or energy levels is supplied to the respective vibrator motors. Frequency differences in the vibrations result in moving interference waves being produced in the rigid member which waves are imparted to the user of the furniture who experiences a massaging effect. Means are provided for enabling the user to control the frequency differential and amplitudes of the driving currents.
Abstract:
A seat cushion pad adapted for use over a seat cushion or against a back cushion. The pad is provided with a motor-driven vibration generator of the unbalanced motor type. The motor has a housing to which is coupled one end of an undulatory spring, which extends from the motor housing substantially throughout the area of the pad, acting as a vibration-transmitting device which transmits vibration throughout the area of the pad and to the body of a user sitting or leaning thereon. The end of the spring opposite from that coupled to the motor housing is free or unanchored, so that the vibration amplitude of the spring is not restricted and reduced to zero by an end anchorage.
Abstract:
A traveling massager assembly adapted for association with a massage table or the backrest of a reclining chair whose body supporting cushioning features a hammock forming sheet of strong and flexible material secured at its perimeter to the cushioning framework, and a relatively thick slab of highly resilient padding having efficient vibration transmitting capabilities supported by said hammock forming sheet without framework attached springs; said cushioning operating in combination with a traveling massage carriage supported by a suspension shaft extending longitudinally of the cushioning framework along the approximate centerline of the hammock forming sheet with the ends of the shaft resiliently and adjustably suspended from the cushioning framework; the massage carriage embracing a series of resilient massage rollers positioned in rolling contact with a tough and flexible inner liner secured to the hammock forming sheet on opposite sides of the shaft, the massage rollers being resiliently supported in cantilever suspension by a roller supporting framework whose center sections are rigidly secured to a vibratory motor supporting baseplate, the carriage baseplate being connected to a carriage suspension member rockably journalled on the shaft by a pair of resilient and flexible mounts secured in spaced relation to the baseplate along the approximate centerline thereof; and driving mechanism for slowly reciprocating the carriage suspension member along the shaft.
Abstract:
A body manipulating and massaging device which includes means for alternately lifting and lowering selected body portions while the body is in a supine condition, to effect a simulated massaging effect; and further, to lift spaced body portions while simultaneously lowering spaced body portions immediately adjacent the lifted body portions and alternating these operations in a rhythmic manner, to further simulate a massaging action.
