Automobile safety belt automatic fastening device and automobile equipped with the device

Abstract

The invention provides a vehicle safety belt automatic tying device and a vehicle provided with the vehicle safety belt automatic tying device. The vehicle safety belt automatic tying device comprises a tying mechanism and a conveyer, wherein the tying mechanism is arranged on a skeleton of a seat and is located beside a lock catch of a safety belt, an inflatable pulling component is arranged inside the tying mechanism, the inflatable pulling component comprises an inflation and deflation unit, a gas storing belt, a magnetic buckle and an electric gas storing belt retracting and releasing disc, the inflation and deflation unit is communicated with one end of the gas storing belt, the other end of the gas storing belt is coiled on the electric gas storing belt retracting and releasing disc, the magnetic buckle is arranged on the top part of the gas storing belt, the conveyor sleeves a safety belt braid and can freely slide on the safety belt braid, and the conveyor is provided with a conveyor lock catch matched with the magnetic buckle and a strong magnet used for absorbing a safety belt plug-in buckle. The safety hidden danger caused by the fact that a passenger forgets to tie the safety belt is eliminated, and the sitting comfort of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automatic safety belt fastening device for automobiles and an automobile equipped with the device. Background technique [0002] The configuration of the car seat belt is an extremely effective safety protection measure. When the car collides or encounters emergency braking in an unexpected situation, it will generate a huge inertial force, which will make the occupant and the steering wheel, windshield, seat in the car Collision of objects such as the backrest can easily cause physical injury to the occupant, and even throw the occupant off the seat or out of the vehicle. The car seat belt can restrain the occupant on the seat, and its cushioning effect can absorb a large amount of kinetic energy, reducing the degree of injury to the occupant. [0003] At present, the three-point seat belt commonly used in automobiles needs to be fastened manually. The action process is ...

AI Technical Summary

Problems solved by technology

For the first solution, due to the limitation of the body column or seat space structure of the family car, it is difficult to realize the reasonable layout of the mechanical transmission structure, and the actual stroke of the transmission structure is limited, so this technical solution is only applicable to the coupe type. Smaller; and the second scheme needs to completely change the structure of the existing seat belt and seat belt retractor, and the practical performance is poor

In addition, both of the above two solutions require the occupant to cooperate with both hands to complete the seat belt fastening process, which affects the ride comfort of the vehicle.
