Airbag: meaning, definitions and examples

Etymology

• The term 'airbag' was first used in the mid-1970s to describe the inflatable safety device.
• The combination of 'air' and 'bag' perfectly describes how the device works: it inflates with air to form a protective cushion.

Engineering

• Airbags are designed to inflate in milliseconds after an impact, reducing the risk of injury to passengers.
• They are made from thin fabric and can withstand high pressures, often using a chemical reaction to fill quickly with gas.
• Most airbags are designed to deflate after deployment, releasing pressure to allow the passenger to move.

Safety Statistics

• According to studies, airbags can reduce fatal injuries by up to 30% in frontal crashes.
• In the United States, airbag systems have been mandatory in passenger vehicles since 1998.
• More than 300 million airbags are estimated to be installed in vehicles worldwide, significantly contributing to road safety.

Cultural References

• In movies, car crashes often depict airbags deploying dramatically, emphasizing their importance in keeping characters safe.
• There are humorous references that playfully mock the concept of airbags in cartoons and sitcoms, showcasing how they can save the day.

Environmental Impact

• Airbags are usually disposed of in landfills after use, raising concerns about materials that aren't biodegradable.
• Recycling programs for airbags are emerging, aiming to reduce waste and recover valuable materials used in manufacturing.
