Safety strap
Technical field
The present invention relates to a kind of safety strap 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 import Pullman saloon.
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, 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, described attaching parts is 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 the 4th belt body, the end of described first belt body is provided with the first through hole, the end of described second belt body is provided with the second through hole, the end of described 3rd belt body is provided with third through-hole, the end of described 4th belt body is provided with fourth hole, described projection inserts described first through hole respectively, second through hole, in third through-hole and described fourth hole.The safety strap of this structure, chaufeur or passenger run into need as pendant thing etc. the situation needing rapidly disengaging configuration time, attaching parts can be pulled rapidly, projection on attaching parts is extracted from the first through hole, the second through hole, third through-hole and fourth 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 border of described 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 lug boss from directly contacting with waistband with shoulder belt, avoids lug boss to cause damage to shoulder belt and waistband.
In technique scheme, preferably, described projection is provided with plastics block through one end of described first through hole, the second through hole, third through-hole and described fourth hole.Plastics block prevents attaching parts from marking from shoulder belt and waistband, causes safety strap to lose efficacy.
In technique scheme, preferably, described attaching parts is that metal is made of one piece.
In technique scheme, preferably, described attaching parts forms a 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, attaching parts can be pulled rapidly, projection on attaching parts is extracted from the first through hole, the second through hole, third through-hole and fourth 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.
