Abstract
A seat, for example, a wheelchair, comprises a seat part, a backrest part, armrests, and footrests. The seat part and the backrest part have a commonly adjustable width, e.g. the side support portions can essentially be inserted into portions of a central frame part, and transversal bars in the backrest have adjustable widths. The seat part also has adjustable front and rear edges, obtained by adjusting adjustable front and rear support portions. The inclination of the backrest is adjusted by clamping screws mounted in side plate portions provided with slots. The height of the backrest can also be adjusted by displacing an upper portion thereof. The inclination of the footrests is varied by moving hinges having a large frictional force normally holding them stationary.
