WHEEL-CHAIR FOR TRANSPORTING OR ASSISTING THE DISPLACEMENT OF AT LEAST ONE USER, PARTICULARLY FOR A HANDICAPPED PERSON

摘要

The seat of the invention comprises a frame carrying a support for the user, especially a foundation, a nacelle stroller or supporting handles to facilitate walking. The frame comprises two parts connected by a transverse axis articulation. The first part of the frame is provided with two main wheels, whose common axis is located close to the user's weight action line, and at least one support wheel forward or backward. The second part of the chassis rests on the ground by at least one support wheel at the other end of the seat. The wheels can be in diamond pattern, the support wheels being freely Eastern. Preferably, an organ spring connects the two parts of the frame to accumulate and release energy in surmounting obstacles. In the case of a wheelchair, the main wheels are driven manually or by separate motors. Such a device is distinguished by its maneuverability and its ability to overcome obstacles.
