air bag

MAYAFeb 19 2022

hello friends and teacher, my name is maya and today i will talk about the pbl project.when was it created ? Air-filled bladders were in use as early as 1951. The airbag specifically for automobile use is credited independently to the American John W. Hetrick, who filed for an airbag patent on 5 August 1952, that was granted #2,649,311 by the United States Patent Office on 18 August 1953.how does it work? Airbags help your body stop more slowly, reducing the risk of injury and death. ... So even if your body is fastened tight, the same basic law of physics says your head will keep on going and smash into the steering wheel or the glass windshield (windscreen). That's where airbags come in.do air bags hurt?no, but the force of hitting the airbag can cause (less serious) injuries from abrasions to broken bones. If your airbags deploy, your car may be totalled.
