Abstract
A raising wheel chair includes a lifting device with a telescopic guide. With the lifting device, the raising frame can be moved up and down both in sitting and in standing position. It is therefore possible to vary the level of the seat or the footrest. Thanks to the tilted arrangement of the telescopic guide, the user of the chair will, on an upward movement, also be moved closer to the objects of interest. The inclined arrangement of the telescopic guide can provide room for the front wheels and permit a short length of the raising wheel chair.
