Background technology

Along with improving constantly of people's living standard, the quantity of trip constantly increases, and the dependence of the high speed vehicle such as automobile, aircraft, high speed train, steamer is constantly strengthened.But mostly the belt system of these main vehicle uses is two-point form and bikini at present.

Two-point belt is installed on the seat usually, and an end direct connection is on the support of seat base, and the other end is fixed in the snap close that is installed on the seat base support by plate.The ribbon part is across passenger's waist.Use this belt system, passenger's upper body is not protected.When vehicle emergency braking or the vibrations of chance unforeseen circumstances generation severe jolt, force of inertia all concentrates on waist, causes waist injured easily.Simultaneously because upper body is unfixing, head of passenger may be clashed into front-row seats backrest or other facility and injured.Three-point-type safety belt system, a common end is fixed on the support of seat; The other end is fixed on the side supports of back of seat homonymy or on other attendant equipment of the vehicle; A plate is installed on the middle ribbon, during use, is moved plate the another side of seat to, insert in the snap close on the mount pad seat base support.Ribbon also is cross over the waist of another side across waist the time by human chest from shoulder.This safety strap has had bigger improvement than two-point belt from safety performance, has not only protected passenger's waist can also protect upper body.But this belt system can not be with human body force of inertia rectangular distribution, causes body local easily because unbalance stress and injured; Upper body does not obtain general protection in addition, shakes easily and injured.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of easy to use, delicate structure and four point seat belt system that can fine dispersion human body force of inertia when the above-mentioned vehicle take place to jolt vibrations and emergency braking unusually.

The utility model four point seat belt system, comprise: the ribbon across occupant waist is called waistband, the shoulder neonychium of protection passenger's shoulder and neck, device is received in the commentaries on classics that is used to reclaim ribbon and have quick locking function, come out through the shoulder belt that is connected in the middle part of passenger's shoulder, chest, belly and the waistband from change receiving device, be used for fixing waistband and adjust the waistband plate and the waistband length adjustment device of waistband length, be used for fixing the plate snap close according to passenger's needs; When not being used, places safety strap the chair back snap close of safety strap plate.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of four point seat belt system, there are two shoulder belts to change and receive device, these two are changeed the receipts device and not only can strain shoulder belt, and has a quick locking function, when the vehicle at emergency braking or when vibrations take place to jolt unusually, fixing shoulder belt; Left and right sides shoulder, the chest of drawing two shoulder belts process passengers from shoulder belt commentaries on classics receipts device are connected with the middle part of waistband to belly; Left and right sides shoulder belt respectively has a shoulder neonychium, the use material more soft than ribbon made and had hair and detain, when the passenger uses of seat belts, can wrap up with the shoulder belt that the shoulder neonychium will be positioned at shoulder and neck, and buckle neonychium hair button, not only can the baffle safety band can also reduce the friction of safety strap to neck to the compressing of shoulder acting point; The waistband that is connected with shoulder belt is across passenger's waist and hip joint, about a plate is respectively arranged, can insert in the snap close that is installed on the seat bottom support, and can freely bring in the length of regulating waistband by the pulling waistband.

The passenger at first pulls out shoulder belt when using this belt system from changeing to receive the device, overlapped head, then the left and right sides plate on the waistband is inserted in the snap close that is fixed on the seat bottom support, spur the waistband free end as required at last waistband is adjusted to suitable position.

The advantage of this four point seat belt system is: 1. can with the vehicle in braking and the jolt human body force of inertia in when vibrations of meeting accident be distributed on the four points of connection of the safety strap and the vehicle, reduced the force of inertia that single point of attachment must bear, reliability is higher; 2. increased the contact point of safety strap and human body, safety strap is more even to the antagonistic force distribution of human body, and is littler to the injury of human body; 3. protected passenger's upper body effectively; When the vehicle jolted vibrations at emergency braking and meeting accident, fixing human prevented that upper body from striking front back of seat and other position of the vehicle well, also can prevent passenger's double swerve and clashed into the vehicle other is local and injured.
