Description

Safety belt buckle detached from sensing structure

The present invention is related to a safety belt buckle detachment sensing structure, especially a kind of The point-type seat belt buckle is to buckle the full buckle into a disconnected state to sense the electrical connection caused by the failure to buckle, so as to sense and prevent the seat belt function from not being fully buckled.

Press, for a car, seat belt is an important equipment to protect the safety of drivers and passengers First, when the car body is caused by a car accident or emergency braking, the people in the car are likely to move forward due to inertia, resulting in collisions with the front steering wheel or windshield, etc., and even the tilt of the car body causes the people in the car to be thrown out of the car, causing more damage. Serious injury, therefore, the seat belt can effectively restrain the human body to the seat at this time, so as not to be hit and cause serious injury; In addition, the function of the seat belt buckle is to connect the seat belt body and fix the position to achieve the protective effect. According to the purpose, the seat belt can be divided into two types: general use and competitive use. Among them, there is usually only one seat belt for general use.
