the utility model is the akumulatorowego wheelchair having ability to ride my steps to overcome obstacles such as field. traffic and mobility over rough ground.the solution is no\u017cycowa design support frame (16) to regulate the spacing of road wheels (front and rear), which allows the adjustment of the contact wire to the spacing of steps, and a significant degree of slope, after which the cart is moving. enter the stairs is performed backwards.at the time dojechania to first degree should be potencjometrem (2) on joystic in (1) make the marketing team of three wheel contact angle 90 degrees while wysterowaniem joystic (1) to drive back.gradually as soon as higher grades, we potencjometrem the inclination of the seat, which is connected with the upper part of the support frame by a pin moving in guide of the armrest. at the same time, increasing the wheel until the front and rear driving will set to the spacing of the stairs. the rear driving system is the main propulsion system.the front is only directional and stabilizing wheels. the axis of rotation of the contact wire is located above the three wheel diameter of road wheels, which causes with blocked by rank or curb first wheel causes turnover tr\u00f3jramiennej construction team wheels of the angle at which the next circle is on horizontal factors in degree, or curb.three wheel rotate around axis of contact wire is carried out by an independent crown tooth mounted on the outside of the housing powered wheels, which is actuated by the engine coupled with a \u015blimakow\u0105 and transmission elements.the support frame is implemented with two wiper motors mounted in the upper part of the support frame under the armrest, which is denying or dial the propeller gearing screw, thereby adjusting the wheelbase and the inclination of the backrest.Przedmiotem wzoru użytkowego jest konstrukcja akumulatorowego wózka inwalidzkiego mający zdolność wjeżdżania na schody, pokonywania przeszkód terenowych np. krawężników, o
