Seat position
A distance of about 840 mm between the backrest of the seat and the front door-post is needed when the passenger lifts and swings his/her legs to pass the front door-post, while a longer distance gives better comfort. A space of at least 300 mm and for comfort 350 mm from the seat corner to the front door-post, measured longitudinally or skew, is needed to make room for the feet when lifting them in or out of the car. The length of shoes can be 300 mm or sometimes more. The seat should be adjustable fore/aft to a position where the upper portion of the seat backrest is placed at the same horizontal position as the back door-post. Then the whole seat is within reach and a person can use the back door-post for support. Thus, a standing passenger can sit down right on the seat and a wheelchair user can move straight into the car and on the seat, and can easily use a transfer-board.
