WAVE FORM SEATING SURFACE CHAIR

To provide a stand seating surface that sharply decreases contact between a person who passes in seat standing and a person who hands over a space in front of a knee to thereby facilitate passing greatly in which the coming in/out of a seat in the middle to a passage is made to move in an uncomfortable state because a space between the knee of a spectator and a front row backrest is narrow in the stands such as a stadium or a theater, particularly, in the case of woman, the pain of passing while contacting to the person exists without being solved as a social problem.SOLUTION: A wave form seating surface chair of the present invention provides a semicircular recess of a degree of containing a knee to a border of a central part and a next seat of a stand seating surface, and thereby secures a space in front of the knee widely by slanting the direction of the knee and putting the knee part in a semicircular recess. By this device, usually a space in front of the knee is widened by approximately 10 cm, and thereby the seat standing movement without excessive contact with others becomes possible.SELECTED DRAWING: Figure 2 【課題】スタジアムや劇場などの観覧席に於いて中程の座席から通路への出入りは観客の膝と前列背もたれとのスペースが狭く、窮屈な状態で移動している。とりわけ女性の場合、人に接触しながら通らなければならない苦痛は、社会的な課題として解決されないまま存在している。従って、席立ち通行する人と膝前スペースを譲る人の接触が激減し、極めて通行しやすくなる観覧席座面を提供する。【解決手段】本発明は観覧席座面の中央部と隣席の境目に膝が収まる程度の半円形の凹みを施し、膝の向きを斜めにして膝部を半円形の凹みに収め膝前スペースを広く確保する。この工夫によって通常で約１０ｃｍ膝前スペースが広くなり、他人と過剰な接触がない状態での席立ち移動が可能になる。【選択図】図２
