Abstract
Abstract A power driven vehicle for disabled, particularly for children, and which incorportaes a motor driven chassis module, a seat module and an accumulator module, wherein the chassis module incorporates two wheel pair units, which are disconnectable from each other and constitute a first, front wheel unit and a second, rear wheel unit, one of the wheel pair units, preferably the first wheel unit, incorporating two steering and driving units acting individually upon one wheel each, the second wheel unit being composed by a central beam, one end of which is connectable to the first wheel unit and having at its other end a yoke pivotably supported transversely to the longitudinal direction of the vehicle, and having at its free ends wheels supported in bearings, and said seat module being centrally arranged on the beam, whereas said accumulator module is attached on both sides of the beam, between the pairs of wheels.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A power driven vehicle for disabled, comprising a motor driven chassis module, a seat module and an accumulator module, the chassis module incorporating two wheel pair units which are disconnectable from each other; the wheel pair units comprising a front wheel unit and a rear wheel unit, the front wheel unit comprising two steering and drive units each acting individually upon one wheel, and the rear wheel unit comprising a central beam, one end of the beam being separably connectable to the first wheel unit, the other end of the beam having a yoke pivotally supported transversely to the longitudinal direction of the vehicle; the rear wheel unit having at its free ends wheels supported in bearings; the seat module being centrally separably arranged on the beam; the accumulator module being separably attached on both sides of the beam, between the two wheel pair units.
