PROBLEM TO BE SOLVED: To solve the problem that a risk of overturn has to be eliminated or reduced for a user of a wheelchair or a helper concerning an operation to open/close a foot placement base in transferring between the wheelchair and a chair or a bed.SOLUTION: A wheelchair includes: a seat part where an occupant is seated a foot placement base for placing feet of the occupant and wheels for traveling. The seat part includes: a base and a seat arranged on the upper side of the base. The seat is constituted to be slidable by a slide mechanism with respect to the base. The foot placement base and the seat are constituted so as to allow the foot placement base to move backward along with the forward movement of the seat by a link mechanism. First links and second links are arranged to the right and left in front and rear parts. Connection bars being extendable backward are extended from the foot placement base, both of the links are connected by rotation shafts, and then a parallelogram link is formed concerning the wheelchair.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】車椅子の利用者又は介助者にとって椅子やベッドに乗り降りする際、足載せ台を開閉する動作は転倒の危険がある為、皆無又は軽減する必要がある。【解決手段】乗員が着座する座席部と乗員の足を載せる足載せ台と走行用の車輪とを備えた車椅子であって前記座席部はベース部とベース部の上側に設けられたシート部とで構成されておりシート部はベース部に対してスライド機構によってスライド可能に構成され、足載せ台とシート部とはリンク機構によってシート部の前方移動に連動して足載せ台が後方に移動するように構成され、左右の前後に第1リンク、第2リンクが設けられ、足載せ台に後ろに伸びる連結棒が伸びていて両者が回転軸により連結されて平行四辺形のリンクができる車椅子。【選択図】図1
