ACTIVE BUFFER FOR VEHICLE AND ELASTIC CYLINDER FOR ACTIVE BUFFER Russian patent published in 2019 - IPC B60R21/239 B60R21/206 B60R21/215 B60R21/217 B60R21/235 

FIELD: physics.

SUBSTANCE: group of inventions relates to an active buffer, which is installed on the surface of the interior trim of the passenger compartment in a motor vehicle, and an elastic balloon for it. In the method, a molded plastic front wall is deployed in the direction of deployment to the passenger in the passenger compartment. Element of elastic balloon formed of plastic is connected along outer perimeter with front wall by heat sealing welding to form inflatable elastic balloon. Elastic balloon element includes at least one substantially circular folded partition. Air pump generates gas for inflation into an inflatable elastic cylinder in response to a collision event of a vehicle. Folding partition wall forms a plurality of at least five openings of the vent valve, including at least one venting valve adjacent to the area of peak mechanical stresses of the welding seam of heat welding, and a plurality of tuning ventilation valves, which are concentrated in the area of the lowest efforts of restriction of the inflatable elastic balloon motion.

EFFECT: improved safety.
