Safety strap
Technical field
The present invention relates to a kind of safety strap 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 import Pullman saloon.
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 is 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: safety strap, comprise shoulder belt and waistband, also comprise an attaching parts, on described attaching parts, be provided with four projections, 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, the end of described the first belt body is provided with the first through hole, the end of described the second belt body is provided with the second through hole, the end of described the 3rd belt body is provided with third through-hole, the end of described four-tape body is provided with fourth hole, described projection is inserted respectively described the first through hole, the second through hole, in third through-hole and described fourth 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 attaching parts, projection on attaching parts is extracted from the first through hole, the second through hole, third through-hole and fourth 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, the border of described the first through hole, the second through hole, third through-hole and described fourth hole is provided with metal hemming edge.Metal hemming edge is used for preventing that lug boss from directly contacting with waistband with shoulder belt, avoids lug boss to cause damage to shoulder belt and waistband.
In technique scheme, preferred, described projection is provided with plastics block through one end of described the first through hole, the second through hole, third through-hole and described fourth hole.Plastics block prevents that attaching parts from marking from shoulder belt and waistband, causes safety strap to lose efficacy.
In technique scheme, preferred, described attaching parts is that metal is made of one piece.
In technique scheme, preferred, on described attaching parts, form a 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 attaching parts, projection on attaching parts is extracted from the first through hole, the second through hole, third through-hole and fourth 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, safety strap, comprise shoulder belt 1, waistband 2 and attaching parts 3, shoulder belt 1 is divided into the first belt body 11 and the second belt body 12, waistband 2 is divided into the 3rd belt body 21 and four-tape body 22, the end of the first belt body 11 is provided with the first through hole 101, the end of the second belt body 12 is provided with the second through hole 102, the end of the 3rd belt body 21 is provided with third through-hole 201, the end of four-tape body 22 is provided with fourth hole 202, the first through hole 101, the second through hole 102, the border of third through-hole 201 and fourth hole 202 is provided with metal hemming edge 4.
Attaching parts 3 is made of one piece for metal.On attaching parts 3, be provided with four projections 31, on attaching parts 3, form a draw ring 32.Projection 31 is inserted respectively in the first through hole 101, the second through hole 102, third through-hole 201 and fourth hole 202.Projection 31 is provided with plastics block 5 through one end of the first through hole 101, the second through hole 102, third through-hole 201 and fourth hole 204.
