FIELD: transportation.
SUBSTANCE: adaptive transport chair of higher safety is turned by 180° in respect to direction of motion and comprises a seat, a back, their common sides and a headrest, equipped with soft cushions. Cushions of the back, sides and the headrest are made in the form of mechanically fixed and tightly isolated sections of a single elastic and air filled reservoir. At the same time the section of the back cushion is connected to each of the sections of cushions of both sides and the headrest by two locking air controlled valves with the set threshold opening pressure difference. The initial working air pressure in the section of the back cushion is developed as considerably exceeding the same pressures in the sections of the side and headrest cushions with exceeded set threshold locking valve opening pressure difference under power inertial impact of the seat user at the back cushion in case of emergency braking.
EFFECT: increased safety upon collision of a vehicle, simplified design.
