What Are the Specifications and Models of Seat Belts?

[Kathleen]

Seat belt specifications and models are divided into: three-point seat belts, two-point seat belts, and four-point seat belts. The function of seat belts: The function of seat belts is to reduce the likelihood of death or serious injury in traffic collisions by minimizing the secondary impact forces that pose internal collision risks. They ensure proper positioning of occupants to maximize the effectiveness of airbags (if equipped) and prevent occupants from being ejected from the vehicle or experiencing rollovers during a collision. How to use seat belts: When wearing a seat belt correctly, the shoulder strap should cross the chest, and the lap belt should fit snugly against the hip bones. This is primarily to direct the impact forces during an accident onto the bones rather than the soft internal organs. Although the buckle will make a "click" sound when fastened, it is still necessary to tug on the seat belt to ensure that the buckle is securely fastened and undamaged. This is a step many car owners overlook when using seat belts.
