Abstract

The invention discloses a safety belt which comprises a woven tape, a lock tongue and a lock body, wherein the lock tongue and the lock body are arranged on the woven tape in a penetrating mode. A hole is formed in the lock tongue. A clamp groove is formed in the lock body. The lock tongue is inserted into the clamp groove. A check block, a spring and an electromagnet are arranged in the lock body. The check block and the electromagnet are located on the two sides of the clamp groove respectively. The check block is in sliding connection with the interior of the lock body. The spring enables the other end of the check block to move towards the direction away from the lock tongue. The two ends of a coil of the electromagnet are connected with buses of a vehicle. When the vehicle is started, the coil is powered to attract the check block to rotate, and then the check block is inserted into the hole. When the vehicle is shut down, the coil loses power, and the check block retreats from the hole under the action of the spring.

Description

A kind of 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.As after there is great traffic accident, car body gross distortion, chaufeur also often loses consciousness, and at this moment safety strap also ties up on chaufeur or passenger's body.Unfasten one's seat-belt and need to press the button at safety belt lock place, this button is generally all arranged on the position near central vehicle.In vehicle gross distortion, rescue personnel is difficult to walk around the wounded and unfastens one's seat-belt, and this just makes the wounded to rescue.

Summary of the invention

The present invention is directed to deficiency of the prior art, a kind of seat belt for cars is provided, can when automobile shuts down, automatically throw off.

For solving the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of safety strap, comprise ribbon, be located in dead bolt and lock body on described ribbon, on described dead bolt, arrange porose, on described lock body, be provided with draw-in groove, described dead bolt inserts in described draw-in groove, in described lock body, be provided with block, spring and electromagnet, described block and described electromagnet lay respectively at the both sides of described draw-in groove, described block is slidably connected in described lock body, described spring makes the other end of described block move towards the direction away from described dead bolt, the coil two ends of described electromagnet are connected with the bus of vehicle, during vehicle launch, coil obtains electric, attracting described block to rotate is inserted in described hole, when vehicle stops working, coil losing electricity, described block exits in described hole under the effect of described spring.This just can be for when meeting an automobile accident, even if chaufeur loses consciousness, but driving engine is flame-out, and at this moment safety strap just can directly be pulled away by rescue group, conveniently sues and labours.Chaufeur, after parking of automobile, also need not be pressed the button of safety belt lock simultaneously, directly just can take off safety strap, very convenient.

In technique scheme, preferred, the both sides of described draw-in groove are provided with inwardly protruded elastic-friction pad, and when described dead bolt inserts described draw-in groove, described friction pad props up the both sides of described dead bolt.Friction pad prevents that, in automobile flameout, safety strap is directly regained.

In technique scheme, concrete, in described lock body, be provided with a cavity, described block is slidably connected in described cavity, and the two ends of described spring are connected with described block with the bottom of described cavity respectively.

The invention has the beneficial effects as follows: when meeting an automobile accident, even if chaufeur loses consciousness, but driving engine is flame-out, and at this moment safety strap just can directly be pulled away by rescue group, conveniently sues and labours.Chaufeur, after parking of automobile, also need not be pressed the button of safety belt lock simultaneously, directly just can take off safety strap, very convenient.

Fig. 1 is schematic diagram of the present invention.

Fig. 2 is the schematic diagram of the present invention while being in the lock state.

Fig. 3 is the schematic diagram of the present invention in the state of unlocking.

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. 3, a kind of safety strap, comprise ribbon 1, be located in dead bolt 2 and lock body 3 on ribbon, on dead bolt 2, arrange porose 21, on lock body 3, be provided with draw-in groove 31, the both sides of draw-in groove 31 are provided with inwardly protruded elastic-friction pad 35, and when dead bolt 2 inserts draw-in groove 31, friction pad 35 props up the both sides of dead bolt 2.

In lock body 3, be provided with block 32, spring 33, electromagnet 34 and cavity 37, block 32 and electromagnet 34 lay respectively at the both sides of draw-in groove 31.

Described block 32 is slidably connected in described cavity 36, and the two ends of described spring 33 are connected with described block 32 with the bottom of described cavity 36 respectively.Spring 33 makes the other end of block 32 rotate towards the direction away from dead bolt 2.

The coil two ends of electromagnet 34 are connected with the bus of vehicle.

Referring to Fig. 2, during vehicle launch, coil obtains electric, and electromagnet 34 attracts block 32 slips to be inserted in hole 21,

Referring to Fig. 3, when vehicle stops working, coil losing electricity, block 32 exits in hole 21 under the effect of spring 33.
