Security system parts for Nissan

In addition to the energy-absorbing elements of the body and interior, the main elements in the passive safety system of a vehicle can be identified: airbags and seat belts. Modern cars use inertia belts. The seat belt with buckle, mechanism and attachment points can withstand a load of more than 1.5 tons. Cars with airbags use seat belts with pretensioners. Previously, a few milliseconds before the airbag is triggered, the pretensioner removes the free play of the seat belt using the built-in pyrotechnic cartridge, having received a command from the electronic safety system control unit. The SRS unit, in the event of a collision, receives signals from several impact sensors located in different areas of the vehicle. Depending on the brand, model and configuration, cars can have a different number of airbags installed, from 0 to 10 or more. There are front and side airbags, they are installed for the driver and passengers. More
