Abstract

The utility model relates to a safety belt, in particular to a safety belt with unchanged effect of wearing comfort, safety and protection. According to the technical scheme provided by the safety belt, a limitator is movably connected with a safety belt body, and the bonding force between the limitator and the safety belt body is larger than the automatic resilience of the safety belt body. The safety belt in use can fully eliminate pressure on a human body by furling pretightening force, avoids the compression sense to the muscles of the human body due to long-term wearing, and does not decrease the degree for protecting the human body in the least.

Description

The comfort type safety strap

Technical field

The utility model relates to a kind of safety strap, especially a kind ofly wears the safety strap comfortable, that safety performance is good.

Background technology

What provide maximum protection to driver and crew in the automotive safety product mainly is safety strap; so almost each car navigating mate all is furnished with safety strap; traffic law also must be worn safety strap in the regulation driving, traffic police even can some not worn safety strap and the behavior of steering vehicle is educated and punished.

Yet wear the safety strap of existing form for a long time, will make the wearer feel very uncomfortable, even the sense of aching that brings user's waist and shoulder, tracing it to its cause mainly is due to the predetermincd tension of safety strap.Though this predetermincd tension is little, compressing makes the muscle of waist and the muscle even the bone of shoulder be difficult to bear for a long time.Taximan and some older chaufeurs are known from experience still dark to this sensation.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can eliminate fully draw in predetermincd tension to the compressing of human body, avoid wearing for a long time the constriction that the human muscle is brought and do not reduce comfort type safety strap at all simultaneously the degree of protection of human body.

Technical scheme according to the utility model provides is connected with limiting device on the safety strap body, and the binding force between limiting device and the safety strap body is greater than the automatic screen resilience of safety strap body.

Described limiting device is the fastener type limiting device, this fastener type limiting device comprises the closed support body of the formation that one or some bodies of rod are end to end, be provided with the connection position-limited lever between the two relative bodies of rod of support body, make the support body of position-limited lever both sides form two through hole, the stage casing of safety strap body is pressed on the position-limited lever, its two ends pass in through hole.

Described limiting device is a pinch roller formula limiting device, the pinch roller that this pinch roller formula limiting device comprises shell and is located at the enclosure upper and lower side, and the safety strap body is located between two pinch rollers and by two pinch rollers and pushes.Two pinch rollers are hinged on enclosure by rotating shaft.

When using, can eliminate comfort type safety strap of the present utility model the constriction of the predetermincd tension of original safety strap fully to the human body generation; its level of comfort can with do not wear safety strap and reach same degree, do not reduce the degree of protection of safety strap simultaneously to human body at all yet.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

Embodiment 1

As Fig. 1, shown in 2: it comprises safety strap body 1, on safety strap body 1, be connected with limiting device 2, this limiting device 2 can be made of metal also and can be made of plastics, and the binding force between limiting device 2 and the safety strap body 1 is greater than the automatic screen resilience of safety strap body 1, described limiting device 2 can be the fastener type limiting device, this fastener type limiting device comprises the closed support body 3 of the formation that one or some bodies of rod are end to end, having little opening is convenient to buckle into the support body 3 of safety strap body 1 and also can, be provided with between the two relative bodies of rod of support body 3 and connect position-limited lever 4, make the support body 3 of position-limited lever 4 both sides form two through hole 5, the stage casing of safety strap body 1 is pressed on the position-limited lever 4, its two ends pass and are against on the support body 3 in through hole 5.

Embodiment 2

As shown in Figure 3: it comprises safety strap body 1, on safety strap body 1, be connected with limiting device 2, this limiting device 2 can be made of metal also and can be made of plastics, and the binding force between limiting device 2 and the safety strap body 1 is greater than the automatic screen resilience of safety strap body 1, described limiting device 2 can be pinch roller formula limiting device, the pinch roller 7 that this pinch roller formula limiting device comprises shell 6 and is located at shell 6 inner upper and lower sides, safety strap body 1 is located between two pinch rollers 7 and by two pinch rollers 7 and pushes, and two pinch rollers 7 preferably are hinged on shell 6 inside by rotating shaft 8.Between described rotating shaft 8 and shell 6, be provided for pinch roller 7 is pressed to the elastic element 9 of safety strap body 1.

Comfort type safety strap of the present utility model is gone up at original safety strap body 1 (traditional with prefastening) increases the limiting device 2 with certain dumping force, its dumping force just can overcome the automatic gathering power of safety strap body 1, after limiting device 2 moves on to certain position, limiting device 2 is parked in and draws a mouthful outside in, make the one section safety strap body 1 that combines with limiting device 2 outside drawing mouth in, be in relaxed state, when being enclosed within such safety strap body 1 on the human body, then safety strap body 1 can not produce constriction to human body at all, then can eliminate the compressing of the gathering predetermincd tension of original safety strap body 1 to human body fully.But when dangerous in case take place, belt with pre-load device tighten up contractive action when beginning, its pretension convergent force can not influence finishing smoothly of its pretension contractive action considerably beyond the dumping force of limiting device 2 at all yet, thereby human body is reached actv. protection.

The mode of wearing with original safety strap when wearing is the same, pull out safety strap body 1 earlier, plug-in unit is inserted in the eye-splice securely, this moment, safety strap body 1 was close to human body surface owing to its self-tightening draws power in, the safety strap that mobile limiting device 2 arrives the human body shoulder draws mouth in, and pulls out safety strap 2～3cm.Limiting device 2 is rested on this position to get final product.Like this, limiting device 2 is not worked when physical activity, can pull out safety strap body 1 in the same old way and makes physical activity freely.Then safety strap body 1 will draw in automatically when human body recovers normal sitting position, till limiting device 2 is run into the gathering mouth, owing to the shock damping action of limiting device 2 no longer tightens up safety strap body 1, thereby eliminate the constriction of 1 pair of human body of safety strap body, can make human body under normal sitting position, wear safety strap body 1 for a long time and do not feel tired, cosily drive a car.When danger generation in a single day, its pretension convergent force can not influence finishing smoothly of its pretension contractive action considerably beyond the dumping force of limiting device 2 at all yet.

Take and finish, unload safety strap body 1 and move lower retainer 2, make in the 1 free retraction fully of safety strap body draws in mouthful.

When using safety strap of the present utility model; the position of its limiting device 2 can only place on the position of pulling out safety strap body 1 about 2～3cm under normal sitting position; just can eliminate the constriction of the predetermincd tension of original safety strap body 1 to human body; can't pull out longly, prevent that safety strap body 1 overrelaxation from will have a strong impact on the safety guard-safeguard to human body.
