A vehicle for the disabled comprising a wheel-chair with seat and back-rest, on the chassis of which two coaxial rear wheels and at least one front wheel are mounted, a cycle frame arranged behind the wheel-chair with a drive wheel drivable by means of pedals, a saddle and coupling device, mounted pivotably on a steering bearing of the cycle frame about a substantially vertical pivot axis, for the detachable connection of the wheel-chair with the cycle frame, the coupling device having at least one cross-member extending transversely of the longitudinal axis of the cycle frame, which cross-member is securable to the wheel-chair chassis through two coupling elements spaced from one another in the transverse direction and supports the forward end of the cycle frame on the chassis of the wheel-chair, is characterized in that the steering bearing (35) carrying the coupling device is connected with the cycle frame (2) through a joint (42) with substantially horizontal pivot axis but otherwise substantially rigidly in rotation. |
