METHOD OF AND DEVICE TO PREVENT INJURIES AND DEATH OF HUMANS IN ROAD ACCIDENTS Russian patent published in 2004 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to safety devices installed on vehicles and designed to protect humans outside the vehicle. Cylindrical member with elastic envelope under 1.5-2 atm inner pressure is secured on front part of vehicle over its width horizontally at level of radiator. In case of encounting with human, the latter is gripped, fixed and lifted to height of 10-20 cm from road bed. Device contains receiver connected by pneumatic lines through electromagnetic valves with springs with pneumatic cylinders whose rods are mechanically connected with pedals of clutch and brake, and source. Rod of pneumatic cylinder with valve is rigidly coupled with front wall of elastic cylindrical member, with piston height of member found from formula h=d+0.5Δ where d is diameter of hole made in side of pneumatic cylinder; Δ is deflection of elastic cylindrical member at encounter with human. Hole is connected by pneumatic line with pneumatic valve which acts onto contacts electrically connected through current source with electromagnetic valves whose outputs are connected by pneumatic lines with four pneumatic cylinders. Rods of two cylinders are rigidly connected with bases of right-hand and left-hand grips, respectively, and rods of other two cylinders are installed for displacement in vertical plane relative to grips.

EFFECT: improved safety, prevention of injuries and death of humans in case of encounter with vehicle.
