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 for the assurance passenger safety on automobile.
Background technology
" safety " become the problem of chaufeur and occupant's overriding concern, is also one of most important performances such as automobile.The parts of traditional assurance 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 application on car.
Yet the safety strap as protection chaufeur and passenger life also can become the killer who threatens chaufeur and passenger life sometimes.The pendant thing that the place ahead once just occurred to occur in Vehicle Driving Cycle process is pounded and is worn glass, threaten the life of chaufeur, at this moment chaufeur instinct wants that pulling open safety strap escapes, 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 unfasten one's seat-belt by pressing button, be then just free to activity, in case of emergency, chaufeur natural reaction is exactly desperately to draw safety strap, and presses snap close button, on the time, has little time.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of safety strap that can depart from is fast provided, 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 four-tape body, one end of described the first belt body and described the 3rd belt body is fixed on described the first attaching parts, described the second belt body and described four-tape body one end are fixed on described the second attaching parts, on described the first attaching parts, be provided with projection, on described the second attaching parts, be provided with through hole, described projection is inserted in described through hole.The safety strap of this structure, chaufeur or passenger, run into need to need rapidly the situation of disengaging configuration as pendant thing etc. time, can pull rapidly the first attaching parts, projection on attaching parts is extracted from through hole, shoulder belt and waistband all separate like this, 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, also can not make attaching parts deviate from, and guarantees driver or passenger's safety.
In technique scheme, preferred, described the first attaching parts is provided with the barb that elastomeric material is made on the position corresponding with the second attaching parts.When projection is extracted with respect to through hole, mutually stuck between barb, prevent that projection from deviating from through hole, safety strap was lost efficacy.But pay special attention to, the intensity of barb can not be too high, otherwise while pulling the first attaching parts, barb can not be destroyed, and this just makes emergency escape meet difficulty.
In technique scheme, preferred, the outer ring of described through hole is provided with metal hemming edge.Metal hemming edge can prevent that projection from contacting with four-tape body with the second belt body, avoids belt body to damage.
In technique scheme, preferred, on described the first attaching parts, be provided with draw ring.
The invention has the beneficial effects as follows: chaufeur or passenger, run into need to need rapidly the situation of disengaging configuration as pendant thing etc. time, can pull rapidly the first attaching parts, projection on attaching parts is extracted from through hole, shoulder belt and waistband all separate like this, 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, also can not make attaching parts deviate from, and guarantees driver or passenger's safety.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail: referring to Fig. 1 to Fig. 4, a kind of safety strap that can depart from fast, comprises shoulder belt 1, waistband 2, the 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 one end that waistband 2 is divided into the 3rd belt body 21 and four-tape body 22, the first belt bodies 11 and the 3rd belt body 21 is fixed on the first attaching parts 3.
The second belt body 12 and four-tape body 22 one end are fixed on the second attaching parts 4, be provided with on projection 31, the second attaching partss 4 and be provided with through hole 41 on the first attaching parts 3, and projection 31 is inserted in through hole 41.The outer ring of through hole 41 is provided with metal hemming edge 42.
The first attaching parts 3 and the second attaching parts 4 are provided with the barb 5 that elastomeric material is made on corresponding position.On the first attaching parts 3, be provided with draw ring 32.
When in case of emergency, people's both hands are pulled on draw ring, towards projection axially pull the first attaching parts, barb 5 is destroyed, the first attaching parts is separated with the second attaching parts, also just makes personnel depart from from safety strap.
