On which road sections can seat belts be unfastened?
1 Answers
Seat belts must be fastened on all road sections. Below is relevant information about automotive seat belts: 1. Concept: Automotive seat belts are safety devices designed to restrain occupants during collisions, preventing secondary impacts with steering wheels, dashboards, or ejection from the vehicle that could cause fatalities or injuries. Also known as seat safety harnesses, they are a type of occupant restraint system. Universally recognized as the most cost-effective yet efficient safety feature, many countries mandate their installation in vehicles. 2. Working principle: The retractor stores the webbing and locks it when pulled out, making it the most complex mechanical component in the seat belt system. Inside the retractor lies a ratchet mechanism. Under normal circumstances, occupants can smoothly pull the webbing at a consistent speed, but when the webbing stops being extracted or the vehicle encounters an emergency, the ratchet mechanism activates to automatically lock the webbing, preventing further extension. Mounting fixtures include tabs, plugs, and bolts connected to the vehicle body or seat components. Their installation position and stability directly affect both the protective efficacy of the seat belt and occupant comfort.
