Massage chair

Abstract

A massage chair includes a main frame, a seat, and a backrest. The main frame includes a back frame configured to support the backrest and a base frame configured to support the seat. The base frame is formed by combining a plurality of structural members. The plurality of structural members are arranged on positions corresponding to edges of a hexahedron. Part of the back frame serves as part of the structural members of the base frame.

1 . A massage chair comprising:
 a seat on which a user can sit;   a backrest in which a massage head is put, said backrest being configured to support the user's back;   a base frame configured to support the seat; and   a back frame configured to support the backrest,   wherein the base frame is formed by combining a plurality of structural members, said plurality of structural members being arranged on positions corresponding to edges of a hexahedron, and   wherein part of the back frame serves as part of the structural members of the base frame.   
     
     
         2 . The massage chair as set forth in  claim 1 ,
 wherein the base frame is constructed in a closed frame shape in a planar view, and   wherein the back frame is constructed in a closed frame shape.   
     
     
         3 . The massage chair as set forth in  claim 1 ,
 wherein the back frame includes a horizontal rod member elongated in the right-left direction, in the lower end thereof, and   wherein the horizontal rod member serves as a structural member of the base frame, said structural member served by the horizontal rod member being the structural member of a position corresponding to one edge of the front of the hexahedron constructed by the structural members.   
     
     
         4 . The massage chair as set forth in  claim 3 , wherein said structural member of the base frame served by the horizontal rod member is the structural member of a position corresponding to the lower front edge of the hexahedron constructed by the structural members. 
     
     
         5 . The massage chair as set forth in  claim 4 , wherein the horizontal rod member of the back frame is located rearwardly than the front end of the base frame. 
     
     
         6 . The massage chair as set forth in  claim 2 ,
 wherein the back frame includes a horizontal rod member elongated in the right-left direction, in the lower end thereof, and   wherein the horizontal rod member serves as a structural member of the base frame, said structural member served by the horizontal rod member being the structural member of a position corresponding to one edge of the front of the hexahedron constructed by the structural members.   
     
     
         7 . The massage chair as set forth in  claim 6 , wherein said structural member of the base frame served by the horizontal rod member is the structural member of a position corresponding to the lower front edge of the hexahedron constructed by the structural members. 
     
     
         8 . The massage chair as set forth in  claim 7 , wherein the horizontal rod member of the back frame is located rearwardly than the front end of the base frame.
