Abstract
A chair in one aspect of the present invention comprises a leg body and a seat body. The leg body comprises a support frame that supports the seat body. The seat body comprises a frame body and a sheet-like member stretched across the frame body. The frame body has a positioning member provided on a back surface thereof that positions the seat body to be in a seatable state. An amount of protrusion of the positioning member is defined so that the positioning member contacts the frame body while a lowest part of the sheet-like member at the time the sheet-like member is deformed when a user sits down on the seat body is located above a top of the support frame.
Claims14
A chair comprising a leg body and a seat body,
- wherein the leg body comprises a support frame that supports the seat body,
- wherein the seat body comprises a frame body defining a central opening and a sheet member stretched across the frame body and over the central opening, with the frame body including opposing left and right pieces extending in a front-rear direction along left and right sides, respectively, of the frame body and laterally bounding the central opening,
- wherein at least one positioning member extends downward relative to the seat body to contact the support frame and thereby positions the seat body to be in a seatable state, wherein the at least one positioning member comprises a first downwardly protruding portion extending downward from the left piece of the frame body and a second downwardly protruding portion extending downward from the right piece of the frame body, with the first and second downwardly protruding portions being laterally spaced relative to one another, and
- wherein an amount of protrusion of the at least one positioning member is defined so as to maintain a state in which a lowest part of the sheet member, at a time the sheet member is deformed when a user sits down on the seat body, is above a top of the support frame.
