Description

Safety belt monitoring device suitable for passenger car seat

Technical Field

The utility model relates to a car safety field, concretely relates to safety belt monitoring devices suitable for passenger train seat.

Background

The safety belt has the advantages of self-help, safety and safety, and has the functions of restraining displacement and buffering, absorbing impact energy, resolving inertia force and preventing or reducing the injury degree of drivers and passengers. The automobile accident investigation shows that when a front collision happens, if a safety belt is fastened, the death rate can be shortened by 57%, when a side collision happens, the death rate can be shortened by 44%, and when a car is overturned, the death rate can be shortened by 80%.

When the front part of the automobile is in strong collision, the body of a driver moves forwards rapidly due to inertia, the safety belt can try to pull the body of the driver, partial impact energy is absorbed, and meanwhile, the safety air bag is inflated and completely opened in a 'thunder-proof manner' at the same time; then the upper part of the body of the driver sinks to the safety air bag, the gas also starts to escape from the air outlet of the air bag at a constant speed, and most of impact energy is absorbed; the occupant then moves his body back and onto the seat. The whole process takes place almost instantaneously and the occupant is totally passive, in which case passive reliance on supplemental occupant protection systems is the only option.

The safety belts are generally divided into three-point safety belts and two-point safety belts according to vehicle types, and the two-point safety belts are generally arranged on seats of a passenger car or an airplane, so that passengers are prevented from being thrown out of the seats instantly when the car turns over laterally; in recent years, major casualty accidents caused by overturning of passenger cars frequently occur, one important reason is that most passengers of the passenger cars are not fastened with safety belts, but the passengers are not fastened with the safety belts for a plurality of reasons, the main reason is that the passenger cars generally remind the passengers to fasten the safety belts manually in the prior art, but due to national consciousness, part of the passengers are unwilling to fasten the safety belts or unfasten the safety belts in the driving process; therefore, some passenger cars monitoring the passenger car safety belts appear, which check the insertion condition of the safety buckle through a wireless technology and remind passengers according to the detection result; but some passengers sit the safety button that will insert under the buttock, avoid monitoring for there is great potential safety hazard still, and current monitoring system generally is applicable to the passenger train of new product, if with detecting system safety in old-fashioned passenger train, then installs the cost additional height.
