In this way the wheelchair can be used optimally both inside and outside. …<??>Additional positioning possibilities of the seat assembly, for example +/- 90 DEG to the undercarriage, provide the user with new application possibilities. …<??>An optimal operation of the wheelchair is achieved by means of an automatic change-over of the control lever according to the position of the seat assembly. …<IMAGE>… |
