A pressure-sensing massage machine that resolves the problems of difficult assembly and adjustment and the occurrence of operational errors common to a sensing mechanism that uses many components and devices. The massage machine of the present invention is able to monitor the pressure applied to the massage recipient by a motor-driven movably extending massaging member. A flexible member is provided in the transmission located between the massage member and the motor that drives the massage member, and a pressure sensing mechanism monitors the pressure applied to the massage recipient through the flexible displacement of the flexible member.

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.

In a lounger-type massage machine, a back support is reclinable relative to a seat. There is provided a leg rest which is movable between a retracted position where the leg rest is retracted to be held below the seat and a projected position where the leg rest is extended outwardly in front of the seat. A sheet is extended to cover the seat and the leg rest. There is provided a looseness prevention mechanism which pulls an end of the sheet inwardly so as to prevent the loosening of the sheet in both the retracted position and the projected position of the leg rest.

A massaging chair is capable of assuring comfortable use, both in the sitting and lying positions. The massaging chair comprises a seat, a reclining backrest pivotally connected about a pivot axis to the seat so as to be movable between an upright position and a horizontal position with respect to the seat, and a massager is disposed on the side of the reclining backrest to give a massage to a back of a user resting on said seat. A pair of armrests are disposed on the opposite sides of said seat. The armrests are designed to extend arcuately substantially about the pivot axis of the backrest. With this arrangement, the user's arms on the armrests can be kept at a fixed comfortable angular relationship with respect to his or her body, irrespective of the varying angles of the reclining backrest on which the user rests with varying posture. Thus, the massaging chair assures enjoyment to the user of a massage in a comfortable posture irrespective of the angular position of the reclining backrest relative to the seat.

A massaging apparatus has a capability of self-adjusting a massage strength for giving an optimum massaging effect for individual users. The apparatus includes a supporting frame on which a user rest and an applicator projecting from the supporting frame to be pressed against a user's body. The applicator is driven to move for applying a massaging force to the user's body. A pressure sensor is provided to monitor a pressure applied back to the applicator from the user's body as a counter-action of applying the massaging force to the user's body and to provide an output indicative of the monitored pressure. A strength-adjustor is included to vary a projecting amount of the applicator from the supporting frame and/or an operational speed of moving the applicator in order to adjust a massage strength applied to the user's body. The massaging apparatus is characterized to include an auto-controller which is connected to receive the output from the pressure sensor and actuates the strength-adjustor in order to increase and decrease the massage strength in such a manner as to follow the monitored pressure. Whereby, the apparatus is enabled to self-adjust the massage strength in proportion to a force at which the user has its back or desired portion pressed against the applicator.
