What is the main function of seat belts during a collision?

Seat belts can quickly tighten in emergency situations, restraining the occupant in the seat to ensure safety and reduce injuries to drivers and passengers. Here is additional information: 1. Function of seat belts: Seat belts are safety devices used in equipment, such as aircraft or during high-altitude work and performances, to ensure safety. The main materials are polyester, polypropylene, and nylon. Seat belts do not only refer to the webbing; besides the webbing, they are also assembled with other components. 'Seat belts' have become a primary consideration for drivers and passengers and are one of the most important safety features in vehicles. 2. Precautions for wearing seat belts: (1) The lap belt should be worn snugly across the lower part of the hip bones, making contact with the femur. During a collision, the force is applied to the pelvic bones, avoiding severe injuries caused by the belt tightening around the abdomen. (2) The shoulder belt should be worn across the shoulder and chest. These parts of the body can better withstand the restraining force of the seat belt. (3) To tighten the lap belt, pull down on the lap belt at the buckle end while pulling up on the shoulder belt.
During a collision, the seatbelt primarily secures the person in their seat, preventing them from being ejected like a cannonball into the steering wheel or windshield. Last time my friend was involved in a high-speed rear-end collision, it was the seatbelt that saved his life. When the car suddenly stops, the body continues moving forward at the original speed, and the seatbelt instantly tightens to absorb the impact. Specifically, it distributes the force through the shoulder strap and lap belt to sturdy areas like the sternum and pelvis, reducing internal organ injuries. Without a seatbelt, hitting your head directly against the windshield could be fatal, and being ejected through the window is almost certain death. Remember, airbags are designed to work in conjunction with seatbelts, so never skip wearing one.
