A kind of safety strap that can depart from fast
Technical field
The present invention relates to a kind of safety strap that can depart from fast of the guarantee passenger safety on automobile.
Background technology
" safety " has become the problem of chaufeur and occupant's overriding concern, is also one of most important performances such as automobile.The parts of traditional guarantee safe driving, as back mirror and left and right door mirror (traditional back-sight visual system), safety strap, AIRBAG(safety air bag) and ABS(anti-blocking brake system) etc. by numerous persons for driving a car and rider be familiar with, and generally to apply on car.
But sometimes also can become as the safety strap of protection chaufeur and passenger life the killer threatening chaufeur and passenger life.The pendant thing that front once just occurred to occur in vehicle travel process is pounded and is worn glass, threaten the life of chaufeur, at this moment chaufeur instinct want pull open safety strap escape, during wrench safety strap, safety strap will be locked, cause chaufeur locked on chair by safety strap, finally make chaufeur be fallen thing and injure by a crashing object.
Although chaufeur is in the process of moving, also can by pressing button, unfasten one's seat-belt, be then just free to activity, in case of emergency, chaufeur natural reaction is exactly desperately draw safety strap, and pressing snap close button, and the time has little time.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of safety strap that can depart from fast, can in case of emergency, untie rapidly.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of safety strap that can depart from fast, comprise shoulder belt and waistband, also comprise first attaching parts and the second attaching parts, described shoulder belt is divided into the first belt body and the second belt body, described waistband is divided into the 3rd belt body and the 4th belt body, one end of described first belt body and described 3rd belt body is fixed on described first attaching parts, described second belt body and described 4th belt body one end are fixed on described second attaching parts, described first attaching parts is provided with projection, described second attaching parts is provided with through hole, described projection is inserted in described through hole.The safety strap of this structure, chaufeur or passenger run into need as pendant thing etc. the situation needing rapidly disengaging configuration time, the first attaching parts can be pulled rapidly, projection on attaching parts is extracted from through hole, such shoulder belt and waistband all separate, and chaufeur and passenger can calm leaving from seat.Meanwhile, if automobile emergency brake or have an accident, what shoulder belt and waistband were mainly subject to is pulling force effect, and attaching parts also can not be made to deviate from, and ensures the safety of driver or passenger.
In technique scheme, preferably, the position that described first attaching parts is corresponding with the second attaching parts is provided with the barb that elastomeric material is made.When projection is extracted relative to through hole, mutually stuck between barb, prevent projection from deviating from through hole, safety strap was lost efficacy.But it is specifically intended that the intensity of barb can not be too high, otherwise when pulling the first attaching parts, barb can not be destroyed, and this just makes emergency escape meet difficulty.
In technique scheme, preferably, the outer ring of described through hole is provided with metal hemming edge.Metal hemming edge can prevent projection from contacting with the 4th belt body with the second belt body, avoids belt body to damage.
In technique scheme, preferably, described first attaching parts is provided with draw ring.
The invention has the beneficial effects as follows: chaufeur or passenger run into need as pendant thing etc. the situation needing rapidly disengaging configuration time, the first attaching parts can be pulled rapidly, projection on attaching parts is extracted from through hole, such shoulder belt and waistband all separate, and chaufeur and passenger can calm leaving from seat.Meanwhile, if automobile emergency brake or have an accident, what shoulder belt and waistband were mainly subject to is pulling force effect, and attaching parts also can not be made to deviate from, and ensures the safety of driver or passenger.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail: see Fig. 1 to Fig. 4, a kind of safety strap that can depart from fast, comprises shoulder belt 1, waistband 2, first attaching parts 3 and the second attaching parts 4.
Shoulder belt 1 is divided into the first belt body 11 and the second belt body 12, and waistband 2 is divided into one end of the 3rd belt body 21 and the 4th belt body 22, first belt body 11 and the 3rd belt body 21 to be fixed on the first attaching parts 3.
Second belt body 12 and the 4th belt body 22 one end are fixed on the second attaching parts 4, and the first attaching parts 3 is provided with on protruding 31, second attaching parts 4 and is provided with through hole 41, protruding 31 insert in through hole 41.The outer ring of through hole 41 is provided with metal hemming edge 42.
First attaching parts 3 and the corresponding position of the second attaching parts 4 are provided with the barb 5 that elastomeric material is made.First attaching parts 3 is provided with draw ring 32.
When in case of emergency, the both hands of people are pulled on draw ring, and the axis towards projection pulls the first attaching parts, and barb 5 is destroyed, and the first attaching parts is separated with the second attaching parts, also just makes personnel depart from from safety strap.
