A kind of double; two back of the body adjustable automobile seat seat belt
Technical field
The present invention relates to automobile safety protector, particularly to a kind of double; two back of the body adjustable automobile seat seat belt.This car belt is applicable to child and the motroist of different stature, and human body can provide enough restraining forceies, and can balanced disperses impact forces.
Background technology
At present, on automobile, the seat belt of application is commonly obliquely carried over one shoulder three-point safety belt, bikini oblique pull seatbelt wearing is convenient, but automobile is when running at high speed, bikini oblique pull seat belt is not provided that enough restraining forceies to human body, and when automobile front is by hard hit, human body will bear great pressure at the position of oblique pull seat belt, human body is easily made to come to harm at the position of oblique pull seat belt, even cause fracture, when there is the shock rolling or meeting with from side in car, occupant can not be fixed on seat more restfully, cause the physical displacement of occupant, therefore also have can not balanced disperses impact forces for bikini oblique pull seat belt, the protected area of shoulders of human body is less, the defect of position adjustment more can not be carried out according to the width of shoulders of human body.
Additionally; traditional three-point safety belt is to design by normal height person; the position of the seat belt tiltedly carried on the arm is in the chest of motroist, and for child and runty motroist, three-point safety belt is not appropriate for using; reason is: the position of the seat belt tiltedly carried on the arm is fixing; can not being adjusted according to height, the position of seat belt can be in the cervical region of motroist, in emergency circumstances not only can not protect; can be fasten child and runty motroist's cervical region on the contrary, causes secondary injury;
Recently as the high speed development of Domestic Automotive Industry, the increase of China's automobile pollution, the accident rate of various children ridings also increases rapidly, and the safety problem of children riding becomes the problem that people extremely pay close attention to.It is typically different the child of age bracket, it is necessary to different types of child safety seat provides protection.
Abroad, the use of child safety seat is very universal, and in China, the utilization rate of children's seat or child belt is but very low.Its reason has the following aspects:
First: children riding security study is started late by China, do not issue and implement relevant laws and regulations so far yet, do not force children riding to use child safety seat or child belt;
Secondly: China father and mother shortage to children riding safety consciousness, when the head of a family generally believes by bus, child is embraced safety in bosom, it is not necessary that use child safety seat or child belt;
3rd: children's seat price comparison is expensive.
4th: child safety seat volume is big, get on the bus and need to install, get off and need dismounting, and it is inconvenient, adult belt is not suitable for child and uses, and when being in that automobile emergency brake or head-on crash, child's neck place is easily caused compressing to suffocate by adult belt, when rolling or meet with the shock from side, occupant cannot be fixed on seat more restfully and be caused the physical displacement to child passenger or the injury thrown away.
How to solve this problem and just become the problem that those skilled in the art to study and to solve.
Summary of the invention
The purpose of the present invention is exactly for overcoming the deficiencies in the prior art, it is directed to traditional three-point safety belt Problems existing, the design of a kind of double, two back of the body adjustable automobile seat seat belt is provided, on the basis of traditional three-point safety belt, carry out structure improvement, with the addition of an oblique seat belt as a supplement, increase chest seat belt adjustable positioning assembly simultaneously, shoulder safety belt adjustable positioning assembly, coordinate with original three-point safety belt, constitute by shoulder width adjustable, the adjustable X-shaped seat belt of double, two back of the body that chest intersects, adjustable X-shaped seat belt is carried on the back by intersecting at the double, two of occupant front, make to traverse in occupant thoracic cavity and invade formula impact force and spread more evenly across, seat belt can the shoulder of occupant be fixed, thus being effectively prevented the physical displacement of occupant, the not used time, this seat belt can in indentation heater coiler.
