What are the main passive safety devices in automobiles?

Passive safety devices include: airbags, seat belts, anti-collision beams, head and neck protection devices, etc. The following is a related introduction to passive safety devices: 1. Concept: Passive safety devices refer to safety devices that can minimize personal injury after a traffic accident, including protection for passengers and pedestrians. 2. Main classification: One type is active safety devices, designed to improve the controllability of the car and prevent the car from losing control and causing accidents as much as possible. Their role is to prevent accidents from happening. Such as anti-lock braking system, electronic stability program, brake assist system, active headlights, etc.; the other type is passive safety devices, whose role is to protect personnel to the greatest extent after an accident occurs, reducing the degree of injury (mainly for people in the car).
Last time my car got rear-ended, I was really grateful for the passive safety features in the vehicle. These devices mainly protect occupants during accidents, with the most basic being seat belts, which prevent people from being thrown out. Airbags are also crucial, and many cars now have multiple airbags, such as head airbags and knee airbags. The vehicle's body structure is quite important too—well-designed components like front and rear crash beams and door impact bars can absorb collision energy. By the way, headrests aren’t just for comfort; they protect the neck from whiplash injuries during rear-end collisions. Even the glass is carefully designed—laminated glass won’t shatter into sharp pieces that could injure people. When these features work together, they maximize survival chances in a crash.
