CHAIR-TYPE MASSAGE MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a chair-type massage machine with excellent usability by automatically regulating the amount of forward projection of treaters from a backrest surface in response to the body type of a person to be treated with a simple structure. SOLUTION: A treatment unit 7 for performing a massage treatment by allowing the treaters 6 to be abutted onto the back of the person to be treated leaning against the backrest surface 5 of a backrest part 3 is arranged in a backrest base part 4 constituting the main body of the backrest part 3 of a chair body 2. Elastic bodies 8 are held between the configuration material of the backrest surface 5 and the backrest base part 4, so as to vary the position of the backrest surface 5 in a front and rear direction by the extension/contraction of the elastic bodies 8. Then, the amount of forward projection of the treaters 6 from the backrest surface 5 is changed in response to the front/rear position of the backrest surface 5. COPYRIGHT: (C)2009,JPO&INPIT
