Abstract
A wheelchair for the disabled and sick in which two rear wheels (1) are each connected to an electric motor drive disposed on the rear axle (2) of each rear wheel (1) and each rear wheel is individually spring mounted in relation to the underframe (5) of the wheelchair by a spring member (6) which is coupled to the underframe (5) and the drive (3). A rocker identically configured for use on the right and left is mounted with its front end in a horizontal axis (8) on a longitudinal bar (9) of the underframe so as to be pivotable with respect to height, and with its rear longitudinal end the rocker is supported on the underframe longitudinal bar (9) and the spring member (6) coupled to the rocker (7). Drive (3 or 4) is attached to the rocker (7). Between the two rockers is a free space (FR) extending from the rear side of the wheelchair to the pivoting axes (8) of the rocker for easy insertion of a battery at the center of gravity.
