The drives 8 are connected with the electric motors 7 and connected by output shafts 9 with external surfaces of the front drive wheels 2. The frame is connected to a case 10 bent along its surface with a user's absorber. The arm rests 6 are hinged 11 with hinges placed on a chair or armchair back and supplied with retainer clips 12 on the opposite ends. The chair or armchair back has a reclining arm rest 13 with a locking gear. The head rest 13 is fixed on the case 10. The arms 4 are placed on chair or armchair legs. The foot rest 5 is demountable. The output shafts 9 are notched for coupling with the external surfaces of the drive wheels 2 located under a chair or armchair seat. The drives 8 are displaced by 3-5 cm by means of lateral motion of linear arms 14 spring-assisted by springs 15 rigidly connected with the drives 8 and hinged and connected by transversal levers 16 with each other and a manual override handle 17. ^ EFFECT: group of inventions provides higher speed and mobility of the wheel chair, usability, simplicity, small dimensions, small weight. ^ 23 cl, 6 dwg |
