Abstract

The invention provides a massager, when a seat part of the massager is inclined due to the expansion of an air bag, the load is reduced relative to the air bag, and the expandable stroke of the air bag is shortened. In the massager provided with the seat part (2) holding the buttock of a patient, which is inclined by using an oblique fulcrum (21) at the rear side of the seat part to change the angle of the seat part (2), a pivot of an auxiliary leg (3) for inclining the seat part before the oblique fulcrum (21) is supported to be lifted on the seat part (2), and the auxiliary leg is connectedwith the air bag (41).

Description

technical field

[0001] The present invention relates to a massage machine capable of changing the inclination of a seat supporting the buttocks of a person to be treated. Background technique

[0002] Among massage machines, there is a massage machine that utilizes the expansion and contraction of an air bag to perform massage, that is, a massage chair with an air pump. Therefore, the applicant attempted to change the inclination of the seat by expanding and contracting air cells different from massage air cells using the air pump.

[0003] However, it is known that a small air pump for massage cannot adopt a structure in which the seat portion is directly raised by the expansion of the airbag. Such as Figure 12 As shown, when the raised position of the airbag 41a relative to the seat 2 is close to the deflection fulcrum 21 of the seat 2, the load on the airbag becomes large and the torque is insufficient. Therefore, it is necessary to replace the airbag 40 with a large a...
