Seat belts have a service life of 3-5 years and should be scrapped in advance if any abnormalities are found. The function of seat belts: Automotive seat belts are safety devices designed to restrain occupants during collisions and prevent secondary collisions between occupants and the steering wheel or dashboard, or to avoid injuries or fatalities caused by occupants being ejected from the vehicle during a collision. Automotive seat belts can also be referred to as safety harnesses, which are a type of occupant restraint system. Usage requirements: Restrain occupants as early as possible; minimize the pressure on occupants during restraint; maintain the restraint position to avoid applying force to the more vulnerable parts of the human body. As a means to achieve these objectives, the use of pre-tensioners and load limiters as described above has significantly improved performance in these aspects.

Why does the air conditioning suddenly stop cooling while driving?

Too much debris and dust adhering to the condenser can lead to poor cooling performance. More information about the sudden loss of air conditioning cooling while driving is as follows: 1. Evaporator icing: When driving at high speeds, the water temperature in the engine's cooling circulation system is relatively low, which enhances the cooling effect of the air conditioning condenser. As a result, the temperature of the air conditioning evaporator becomes even lower, potentially causing the surface of the evaporator to ice over. This can block the air intake of the air conditioning system, leading to a loss of cooling and reduced airflow. 2. Alternate between internal and external circulation: When using the air conditioning during high-speed driving, it is advisable to alternate between internal and external circulation. This not only helps maintain fresh air inside the car but also prevents the air conditioning evaporator from icing over, which could affect cooling performance.
