What is the structure of a seat belt?
1 Answers
Seat belt structure consists of three parts: the belt, rope, and metal fittings. Here are detailed introductions about seat belts: 1. Structural types: Single waist belt type, single waist belt plus single shoulder belt type, single waist belt with double shoulder belts and double leg belts type. 2. Basic principle: The ideal functioning process of a seat belt is to tighten promptly and firmly 'press' the person into the seat without hesitation at the first moment of an accident. Then, it moderately loosens after the peak impact force has passed or when the person can be protected by the airbag, appropriately relaxing the seat belt to avoid rib injuries caused by excessive pulling force.
