Definitions

  • the invention relates to a foldable wheelchair with arranged on both sides of the wheelchair side frame, a cross strut and seat tubes for receiving a seat covering, wherein the cross strut, facing away from the seat tubes areas to parallel pivot axes is pivotally mounted in the side frame and the axis of rotation of the struts of the cross strut parallel to these swivel axes the cross strut is arranged, and the cross strut is connected to the seat tubes, which are received in the unfolded position of the wheelchair seat tube bearings of the side frames, the wheelchair on both sides guide lever, and the respective guide lever, in a first region, in a strut of the cross strut , Is mounted in a region of the cross brace between the axis of rotation of the struts of the cross brace and the seat tube, and this guide lever at a distance thereto, in a second region in which this seat tube associated side frame is pivotally mounted about a pivot axis, said pivot axis parallel to the Sw
  • the seat tubes At the upper end of the struts are the seat tubes. They form with the struts a right angle, are aligned in the direction of travel and serve to attach the seat cover. In the unfolded state, thus the use situation of the wheelchair, they are fixed in seat tube bearings attached to the side frames.
  • struts At the lower end of the struts these are hingedly connected to the lower portion of the side frames, wherein the axes of rotation are aligned in the direction of travel. Due to the crossed joint connection of the struts these are connected in the unfolded state of the wheelchair respectively at the lower end with a side frame and stored at the upper end in the other side frame.
  • the seat tubes When folding the wheelchair, the seat tubes are guided by train to a seat covering the wheelchair from the seat tube bearings upwards, the cross strut and thus the entire wheelchair are folded.
  • the side frames are only pivotally connected to the cross strut after the release of the seat tubes from their stock in the lower area, it requires in each case a guide lever to prevent the side frames tilt out of control to the side uncontrolled and controlled out.
  • These guide levers are hinged on the one hand to the upper portion of a side frame and on the other hand to the strut of the crossbar, which is connected to the opposite side frame, respectively.
  • the axes of rotation of the guide lever are also aligned parallel to the direction of travel.
  • the hinge points in the struts of the cross brace are chosen so that the side frames are parallel to each other both in the unfolded, as well as in the folded state.
  • the side frames are pivotally connected in the lower region thereof with the crossbar, they perform there a corresponding rotational movement, so that move the sagittal planes of the side frame from the parallel at an angle to each other and occupy a V-shaped position.
  • Object of the present invention is to develop the foldable wheelchair of the type mentioned so that the aforementioned disadvantages are avoided and a substantially parallel guidance of the side frame of the foldable wheelchair during its entire folding process is possible.
