A massage machine using a small size and high torque brushless DC motor includes a driving unit moved up and down along guide rails of a chair and a first motor for moving the driving unit up and down. A pair of treatment head bases are driven reciprocally in opposite directions to each other; and a second motor reciprocally drives the treatment head bases in opposite directions to each other. Treatment heads are respectively supported by the treatment head bases; and a third motor drives the treatment heads in a plane substantially perpendicular to a backrest. A control circuit drives the respective motors respectively independently of one another. Each motor is a brushless motor. A control circuit corrects, corresponding to a load imposed on the brushless DC motor, a waveform of a drive signal applied to a winding of the brushless DC motor so as to allow a current flowing through the winding of the brushless DC motor to have a substantially sinusoidal waveform making it possible to reduce discomfort due to motor noise, and to accurately control the motor rotation speed.

A chair type massager includes a seat part on which a person to be treated sits on, a backrest part with a reclining mechanism to perform a raising/tilting operation, and right and left armrest parts in which the arms are inserted. The massager further includes air bags provided at the armrest parts, the air bags holding the arms placed in the armrest part by being swelled by air supplied from an air supply pump; a control part for controlling the raising/tilting operation of the backrest part and the air supply to the air bags; and a manipulation part for giving instructions to the control part. When controlling the reclining mechanism to tilt the backrest part in response to the instructions from the manipulation part to perform the arm stretch, the control part controls the air supply pump to supply air into the air bags intermittently.

Chair type massager

A massaging device having an applicator driven by a plurality of driving unit to move along two or more different axes to generate a combined massaging action to be applied to the user's body. A controller holds individual speed data each defining a speed at which each of the driving units reciprocates the applicator along each of the different axes, and to control the driving units to reciprocate the applicator in accordance with the associated speed data. The controller controls the speed of the applicator along one of the axes independently from the speed of the applicator moving along another of the axes. Accordingly, the applicator's movements along the different axes can be free from being interfered with each other even being subject to a load, thereby assuring to continue the combined massaging action.

A massage chair of the present invention includes an electric reclining mechanism for moving a backrest into different sloping positions, left and right holding mechanisms for respectively holding user's left and right forearms, and a controller for controlling operations of the mechanisms. The controller separately controls operations of the electric reclining mechanism and the left holding mechanism as well as operations of the electric reclining mechanism and the right holding mechanism. When controlling the former operations, the controller controls (A) allow the left holding mechanism to hold the left forearm, (B) allow the electric reclining mechanism to recline the backrest to any of the different sloping positions, (C) allow the electric reclining mechanism to raise the backrest to any of the different sloping positions, and (D) allow the left holding mechanism to release the left forearm. Similarly, the controller controls the latter operations.

Massage chair

A massage chair including an electric reclining mechanism for moving a backrest into different sloping positions, a holding mechanism for holding at least one forearm of a user to fix to the base side, and a controller that controls operations of these mechanisms. The controller allows the holding mechanism to hold the at least one forearm and allows the electric reclining mechanism to move the backrest into at least one sloping position before moving the backrest into a final position. An inclination of the at least one sloping position from a sloping position of the different sloping positions when the at least one forearm is held by the holding mechanism is smaller than an inclination of the end position from a sloping position of the different sloping positions when the at least one forearm is held by the holding mechanism.
