Chair

In the chair, a space between swinging surfaces facing each other can be appropriately unseen. The chair includes swinging surfaces (rolling surfaces) () and () facing each other and has a configuration in which the swinging surfaces () and () swings with respect to each other in directions of 360 degrees including front-rear and left-right directions. In such a chair, an elastic member () is arranged to be positioned between the swinging surfaces () and () at least in the vicinity of outer peripheral edges () and (), and a stretchable sheet material () is provided between the outer peripheral edges () and () to conceal a gap between the swinging surfaces () and () facing each other, the gap including the elastic member ().

Chair having a movable seat

Chair legs

To realize a noble, useful seat with a simple structure designed to follow a natural movement of a seated person in front-rear and left-right directions and to support appropriately a movement of the person continuously changing its posture while the person balances a load. The seat includes the elastic support layerand upper and lower base unitsandarranged to sandwich the elastic support layer. The upper base unitincludes the rolling surfacebulging toward the lower base unitthereabove via the elastic support layer, is rollable in a 360&#xb0; direction from the tilt reference position IRP in receiving a load of the seated person, and has a moving distal end side tilting more downward as a distance from the position IRP increases, and is configured to move while compressing the elastic support layerby the rolling surface.

Seat, chair, and load support body

A chair includes a leg, a seatincluding a pressure receiving surface PS, a backrest, and a support mechanism SM. The seatcan move in the front-rear or left-right direction along a predetermined trajectory and to downwardly incline a tip side of the seatin a movement direction in accordance with a movement of the seatfrom a predetermined reference position (S). The support mechanism SM includes a return-force generation unit configured to generate, in accordance with an amount of movement, a return force in a direction in which the seatmoved from the reference position (S) in the front-rear or left-right direction is returned to the reference position (S), and movably supports the backrestin the left-right direction together with a movement of the seatin the left-right direction.

A chair is realized which takes specific measures to suppress movement of a seat in a front-rear direction when the seat swings in the front-rear and the left-right directions with respect to a support base. For the purpose, the chair wherein a seatswings in the front-rear and left-right directions with respect to a support base, the chair is configured such that swinging of the seatin front-rear direction with respect to the support baseis capable of being suppressed at one or a plurality of predetermined positions, or arbitrary position via operation of operation member

Chair whose seat swings in a front-rear direction and a left-right direction

A chair according to the present invention is a chair comprising a legarranged on a floor surface, a leg support poleerected from the leg, a support basefixed at an upper end of the leg support pole, a seatarranged above the support baseand a support mechanisminterposed between the support baseand the seatand configured to support the seatmovably in a front-rear direction and a left-right direction. Additionally, in the support mechanism, a left-right support partis attached to the support basemovably in a left-right direction, a front-rear partis attached to the left-right support partmovably in a front-rear direction, the seatis attached to the front-rear support part, and the support basehas an arm attachment part

[Problem] The present invention provides a chair and a cover member of the chair that include a cover which can appropriately maintain the appearance of the chair while preventing a sitting person from touching a movement mechanism moving below a seat at the time of movement of the seat or a backrest. [Means for Solving the Problem] A chair according to the present invention is provided with cover membersfor covering a movement mechanismto support a seat movably at least one direction of front-rear direction and left-right direction, and is configured so that the cover membersinclude a plurality of through-holesarranged lengthwise and breadthwise.

Chair and cover member of the chair

A chair according to the present invention includes: a leg; a leg support pole; a support base; a movement mechanismlocated below a seat, the movement mechanismprovided with plural movement partsA,B configured to allow the seatto move in a certain area along a predetermined trajectory in a front-rear and left-right directions between the support baseand the seat, the movement mechanismbeing a support mechanism configured to support the seatso that the seatmoves in the front-rear direction and left-right directions; and plural cover membersarranged corresponding to the plural movement partsA,B. The plural cover membersare configured to move relatively in accordance with movement of the plural movement partsA,B and cover the support mechanism
