Abstract

The utility model provides a mobile seat for protecting the safety of car staff, which is based on the existing car seat and has an improvement in the supporter for fixing the car seat. The mobile seat has large and small supporters. The large supporter is a hollow supporter with a full-sealed rear end and a front end cut with a groove, and has a buffer spring in the cavity of the back end. The elastic limit of the spring is sufficient to not only meet the requirement for normal work of the seat but also rapidly contract inwards when the seat is stressed. The groove-shaped front end can not only fix the seat and but also ensure the seat to smoothly move backward. The small supporter is a solid supporter which has a rear end partially inserted into the cavity of the large hollow supporter and has a front end provided with a seat and positioned inside the groove of the large hollow supporter. The front end of the large hollow supporter is sealed to avoid the forward movement of the seat. With the structure, the seat can be used to completely replace the existing safety air-bag for cars, and can protect the car staff.

Description

The activity safety seat

Affiliated field

The utility model relates to a kind of automobile protective seat, in particular the automobile front-row driver and crew take advantage of the movable protection chair of seat.

Background technology

At present, along with the continuous increase of vehicle, traffic accident is also in continuous rising, and the personal casualty that is caused is also in continuous increase, and in traffic accident most reasons of the injures and deaths that cause, be because the injury that vehicle causes bumping back extruding occupant.For this reason, the scientists customized design a kind ofly collide the safety air bag that protective action is played in the back, but this safety air bag is in theory almost rationally intact, in practice but et out of order usually, many vehicles the collision rear gasbag do not open or opening degree not enough, still cause personnel's injures and deaths situation.Simultaneously, because the effect of safety air bag is an iris action in the middle of rising, when running into great collision, can push the situation of caving in together by the company's of causing safety air bag between the two articles that bumps, safety air bag has at this moment just lost its protective effect.

Summary of the invention

The purpose of this utility model: provide a kind of mobilizable protection chair, it is that the automobile front-row driver and crew are being met accident when collision, and institute takes advantage of the seat of seat can be mobile backward rapidly automatically, thereby the occupant is played the seat of insulation blocking effect.

The purpose of this utility model is achieved in that all structure functions that keep original seat, and the installation travel(l)ing rest is set on the support of fixed seat.At first, big hollow sting is set, this support latter half is totally-enclosed, first half then cuts into hold down groove, in fully enclosed latter half hollow sting hollow, a retractable spring is set, its size just in time can be put into hollow sting, and the selection of its elastic limit must be the normal operative condition that can guarantee seat, again can be rapidly to after contraction when the extruding of the prominent chance of seat external force.Little solid support is set then, its size just can be inserted in big hollow sting hollow, seat is fixed on the first half of small rack, in the hollow sting that the rear end part of latter half is inserted in hollow, be connected with prior let-in spring front end, centre portion is arranged in fixing being pickled with grains or in wine and leaves movably distance, the first half of chair of usheing to seat also falls into fixing poor that the first half of big hollow sting sets, seal the front end of big hollow sting, in order to avoid seat is subjected to the effect of spring and moves forward.

After adopting such structure; owing on the fixed support of seat, be provided with the structure that small rack overlaps big support; so this seat can promptly inwardly shrink under the extruding that is subjected to the external force effect;, the drive occupant avoids the extrudate in the place ahead thereby inwardly shrinking; and then reached the protective action of protecting occupant's personal safety, social benefit is played positive effect.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Among the figure: 1 seat, 2 little solid supports, 3 fixing poor, 4 big hollow stings, 5 recoil springs.

Embodiment

Describe the details and the service condition of the concrete device of the utility model in detail below in conjunction with accompanying drawing.

Shown in the figure, this activity protection chair, it is the structure that adopts small rack to overlap big support on the fixed support of seat, and in big hollow sting the inside recoil spring is set and forms.During use, earlier big hollow sting is fixed on the car bottom plate, in hollow sting hollow, put into a recoil spring then, the rear end part of little solid support is inserted in big hollow sting hollow, and be connected with the spring of the inside, the centre is arranged in fixing being pickled with grains or in wine and leaves a part of movable distance, what front end had a fixed seat also falls into fixing poor that big hollow sting pre-sets, and seal the front end of big hollow sting, in order to avoid little solid support moves forward under the effect of spring, use the hand propelled seat, check that whether seat can freely inwardly shrink, and has so just formed a mobilizable protection chair.This device all keeps original functional structure on the structure function of seat; and it is also very simple on the improvement on the fixed support is being made; monolithic chamber inner structure to vehicle can not exert an influence, and effect is to have substituted safety air bag fully, and occupant's safety is shielded more.
