MASSAGE CHAIR
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.
