FIELD: transport.SUBSTANCE: invention relates to automotive industry, particularly, to wheelchair stabilisers. Proposed stabiliser comprises two levers articulated in lengthwise plane, guides and torsion. First lever is longer than the second one and is pivoted thereto by its central part First lever one end is coupled with support wheel axle and second end id coupled with slider in guides. Guide is arranged perpendicular to straight line connecting rotational axes of wheel and torsion. Said torsion is secured at wheelchair seat. Short lever second end is rigidly jointed with torsion. Both ends of long lever are articulated with sliders. Aforesaid sliders make the bearing assemblies for appropriate support wheels. Slider guides are located mutually perpendicular and furnished with controlled-stiffness helical spring to make an induction coil. Spring is located between the slider and common torsion.EFFECT: efficient stabilisation of wheelchair in overcoming stair flights.2 cl, 1 dwg |
