Abstract: A seat having a backrest and a seat cushion is provided with at least one adjusting element on both sides of the longitudinal center plane of the seat. By alternatingly actuating the adjusting elements in the two halves of the seat, mobilization of the spinal column of a seat user occurs. In order to increase the acceptance of such a mobilization, which requires comparatively long stroke lengths of the adjusting elements to achieve a physiological effectiveness, an accustomization phase occurs before the action phase. During the accustomization phase, the adjusting elements exercise, for example, only about half of the stroke during the action phase. Preferably, a transition phase may be interposed between the accustomization phase and the action phase.

Abstract: The invention relates to massages for acupoints in sensitive private parts of male and female private parts. It comprises a cushion shell, knocking and oscillating massagers for acupoints of the private parts, a sponge pad, an arc cover board, a bottom cover of cushion shell, a computer controlling board of integrated circuits and a hand-held switch controller. The knocking and oscillating head for massaging private parts is arranged and mounted at the position of the central line C of the cushion shell. An arc supporting plate for knocking and oscillating massages for private parts on it is installed at the massage head. The distances between each of the knocking massagers can be adjusted within a proper range. The benefits of the invention are its simple structure, good curative effect and convenience in use.

Abstract: A traction chair system for efficiently relieving an individual of lower back pain. The traction chair system includes a chair frame, a seat, a plurality of actuators attached between the chair frame and the seat for elevating/lowering the seat, a backrest, a harness attached to the backrest for securing an individual to the backrest, a motor mechanically elevating/lowering the backrest, and a control unit in communication with the actuators and the motor. A scale is positioned within the seat and in communication with the control unit for providing feedback to the individual regarding the actual amount of traction occurring. The amount of traction being applied to an individual is shown upon a display of the control unit.

Abstract: A rotary device of a chair comprises that has a chair body having a seat. A resisting body extends from a rear end of the seat. An annular handle is installed on the resisting body. The chair body has a driving means mechanism which is installed at the seat. The driving mechanism means has a deceleration motor, a worm rod, a worm gear and a chain. The deceleration motor has a deceleration gear. One end of the deceleration motor has a driving spindle. After the driving spindle is connected with the worm rod, the worm gear will be driven to rotate. The worm gear has a protruded driving shaft. One end of the chain is engaged to the driving shaft, while another end of the chain is engaged to the resisting body. The worm gear indirectly drives the resisting body and the handle.

Abstract: A relaxation apparatus which comprises a reclining chair for supporting thereon a whole body of a person who desires relaxation. The person resting on the reclining chair is cyclically vibrated at a frequency not higher than 25 Hz. A control is provided for controlling the vibrating device. The maximum absolute value of acceleration of the vibration produced by the vibrating device to vibrate the person supported on the reclining chair is not greater than 0.1 G. The control controls the acceleration in dependence on the frequency of vibrations outputted by the vibrating device such that the acceleration is small when the frequency of vibrations outputted by the vibrating device is low while the acceleration is large when the frequency of vibrations is high.

Abstract: A massage chair capable of massaging even the foot by utilizing a whirlpool formed by the spouting of water is disclosed, in which the chair can be moved back and forth, its seatback can be reclined, and the instep and the sole of the foot can be massaged. The massage chair includes a supporting structure 20 and a seat 10. The seat 10 consists of a seat cushion 11 mounted and secured upon the supporting structure 20, and a seatback 12 upstanding on a rear edge of the seat cushion 11. A massaging mechanism 50 is internally installed within the seatback 12, and a seat moving mechanism 40 moves the seat cushion 11 back and forth. A foot bath tub 30 is formed on the supporting structure 20 in front of the seat cushion 11, and the foot bath tub 30 has water spouting holes 31, 32 and 33 on its bottom, on its side walls and on its rear wall respectively, and has a water spouting shower device 34 above it.

Abstract: Machines for treating neuromuscular pain conditions and injuries by slow patient-controlled stretching of a muscle or group of muscles when they and surrounding muscles are in a relaxed state (i.e., with little or no extrafusal muscle fiber contractions). The machines include a fixed support such as seat. An adjustable support, such as a back or side rest is adjusted for the particular patient. A controllable support moved in an alternating motion, under the patient's control, allows the injured or painful muscle to be slowly stretched by gravity, while the muscles are relaxed. The controllable support is preferably moved by a hydraulic cylinder.

Abstract: A device for motioning selected body portions and supporting other body portions of a user seated thereon is provided. The device comprises a base member, a peripheral member, and an ischial pad. The ischial pad is operably connected to the body member and at least partially surrounded by the peripheral member. The ischial pad undulates about two orthogonal axes and relative to the peripheral member. The ischial pad isolates and engages the right and left ischial tuberosities of the user seated on the device for simulating the natural motion of the user's spine. The peripheral member supports the user's body portions proximate the ischium.

Abstract: A method and apparatus is disclosed for periodically and rhythmically lifting one hip of a seated person and then the other, thereby simulating the muscle stimulation and relaxation imparted to a person by walking. A rotatable support panel is provided for alternately lifting and moving backward and forward each hip of a seated person.

Abstract: A mechanized traction chair is disclosed that employs a motor operated underarm support device that in combination with a restrictive seat belt provides forced traction to the upper torso. A lower seating assembly provides a variable articulating motion to the lower torso.

Abstract: A chair provided with at least one leg supporting the chair on the ground, with a back supported by the leg(s) and with a seat supported by the leg(s), whereby the seat is pivotable with respect to the back about an at least substantially vertical axis, wherein by means of a driving member the said seat is pivotable to the left and to the right through maximally 10.degree. from a central position.
