PROBLEM TO BE SOLVED: To solve problems in which a present wheelchair places emphasis on falling prevention and folding compactness and gives a low priority to sitting comfort and rehabilitation effect, although a wheelchair is an important tool for spending a long time, an only moving means, and a chair for having meals, controlling quality of life for a user, in which a present wheelchair has the center of gravity in the rear for the purpose of preventing falling, causes nearly a lying-down posture, and is far from rehabilitation, and in which a person who is able to use one leg is prevented from fully using it, a person who when facing the front from a humpback posture is made to face upward, is given hard-to-drink condition to cause aspiration, and a person who is pressurized in the back tends to have a pressure sore.SOLUTION: The forward-bent wheelchair compensates for weak points of legs, affecting no balance of the whole body. It makes front center of gravity which is the original posture of a person, producing a muscle force to maintain the posture. The wheelchair facilitates use of legs, rectifying a humpback posture. By producing a posture of facing down, it prevents aspiration. The wheelchair releases the user from a burden on his back in bed, demonstrating an effect for preventing pressure sore.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】現状の車いすは、落下しない事、コンパクトに折り畳む事に重点が置かれており、座り心地や、リハビリ効果、などは二の次とされている。しかし、利用者にとっては、長い時間を過ごし、唯一の移動手段であり、食事をするイスでもあり、生活の質を左右する重要な道具である。落下を防ぐため、後ろ重心になっており、寝ている姿勢に近く、リハビリに結びつかない。片脚が使える人でも、その脚を十分に使えない。円背から、正面を向くことで顔の上向きが作られ、飲み込みにくく、誤嚥の原因となる。背中側が圧迫され、褥瘡の原因となる。【解決手段】前傾型車いすは、脚の弱点を補うが、体全体のバランスは崩さない。人、本来の姿勢である前重心を作り、姿勢を保持する筋力がつく。脚は使いやすく、円背を直す。下向きを作ることで誤嚥を防ぐ。ベッド上で背中側にかかっていた負担は開放され、褥瘡予防にも効果を発揮する。【選択図】図1
