Abstract

The utility model discloses an air bag for a helmet. The air bag comprises an air bag body, and the air bag body comprises an upper sealing layer and a lower sealing layer, wherein the periphery of the upper sealing layer and the periphery of the lower sealing layer are connected in a sealed mode. Foam is arranged in the space formed by folding of the upper sealing layer and the lower sealing layer, and an air inlet button and a one-way air valve are arranged on the upper sealing layer or the lower sealing layer in the direction from the inner side of the air bag body to the outer side of the air bag body. The air bag for the helmet is simple and reasonable in structure and exquisite in design, air is exhausted to the one-way air valve when the air bag for the helmet is squeezed, the air inlet button carries out inflation on the air bag for the helmet through the recover characteristics of the foam when the foam is squeezed, the air bag for the helmet can be adjusted according to the size of a user, and the comfort degree of the helmet is improved.

Description

Air bag for the helmet

Technical field

The utility model relates to air bag, particularly a kind of air bag for the helmet.

Background technology

The helmet is a kind of protector be in daily use, and by wearing the helmet, people's head is played a protective role, and prevents from or alleviate in accident head is damaged.Be generally to be provided with the fixing expanded material of volume as the buffer protection layer in the existing helmet, thereby can not carry out buffer protection layer volume size adjustment according to different users's head size, had a strong impact on the comfort level of safety cap.

The utility model content

The purpose of this utility model is, for the problems referred to above, a kind of air bag for the helmet is provided, and it is simple and reasonable, designs ingenious, by the extruding head bladder, exitted by Non-return air valve, by the restoration characteristics after utilizing foam to be squeezed, by the air inlet button, head bladder is inflated, head bladder can be regulated according to user's head size, has improved the level of comfort of the helmet.

The technical scheme that the utility model adopted for achieving the above object is:

A kind of air bag for the helmet, it comprises airbag body, this airbag body comprises that week is along the upper sealant and the lower seal layer that mutually are tightly connected, be provided with foam in the space of sealant and lower seal formation that layer closes up on this, on this, sealant or lower seal layer are provided with one by this airbag body inboard air inlet button and a Non-return air valve toward lateral direction.

Described Non-return air valve comprises valve body and spool, described valve body consists of upper valve body and lower valve body, described upper valve body comprises upper cover body and upper gas column, described lower valve body comprises lower cover and lower gas column, described upper cover body and lower cover fasten mutually and between forms valve pocket, described upper gas column runs through upper cover body and forms protruding hole in the upper cover body bottom, described lower gas column runs through lower cover, described spool is placed in valve pocket, this spool comprises the spool body and is arranged on the leg of spool body bottom, described spool body is boss-shaped, its upper surface and protruding hole fit, described leg contacts with lower cover.

Above sealant is identical with lower seal layer structure, is equipped with a serving, a foaming layer and a sealant layer.

The upper surface of the described spool body formation groove that caves in, described groove and protruding hole fit and make spool body and upper cover body laminating.

Described leg is circle distribution in the bottom of spool body.

The beneficial effects of the utility model are: it is simple and reasonable for the utility model, design ingenious, by the extruding head bladder, by Non-return air valve, exitted, by the restoration characteristics after utilizing foam to be squeezed, by the air inlet button, head bladder is inflated, head bladder can be regulated according to user's head size, has improved the level of comfort of the helmet.

Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the overall structure schematic diagram of Non-return air valve in Fig. 1;

Fig. 3 is cutaway view of the present utility model;

Fig. 4 is the structural representation of the spool of Non-return air valve in the utility model.

The specific embodiment

Embodiment: see Fig. 1 to Fig. 4, a kind of air bag for the helmet of the utility model, it comprises airbag body, this airbag body comprises that week is along the upper sealant 1 and the lower seal layer 2 that mutually are tightly connected, on this, 2, sealant 1 and lower seal layer close up in the space of formation and are provided with foam 3, and on this, sealant 1 or lower seal layer 2 are provided with one by this airbag body inboard air inlet button 4 and a Non-return air valve 5 toward lateral direction.

Above sealant 1 is identical with lower seal layer 2 structure, is equipped with a serving 11, a foaming layer 12 and a sealant layer 13.

Non-return air valve 5 comprises valve body 1 and spool 2, described valve body 1 consists of upper valve body 11 and lower valve body 12, described upper valve body 11 comprises upper cover body 111 and upper gas column 112, described lower valve body 12 comprises lower cover 121 and lower gas column 122, described upper cover body 111 mutually fastens with lower cover 121 and between forms valve pocket 3, described upper gas column 112 runs through upper cover body 111 and forms protruding hole 113 in upper cover body 111 bottoms, described lower gas column 122 runs through lower cover 121, described spool 2 is made by silica gel material, be placed in valve pocket 3, spool 2 comprises spool body 21 and is arranged on spool body 21 bottoms and is the leg 22 of circle distribution, described spool body 21 is boss-shaped, its upper surface caves in and forms groove 23 and fit and make spool body 21 and upper cover body 111 laminatings with protruding hole 113, described leg 22 contacts with lower cover 121.Upper gas column 112 of the present utility model is connected with aerating device, and lower gas column 122 is connected with the protection air cushion, and when giving the inflation of protection air cushion, gas pressure makes spool 2 leave the protruding hole 113 of upper cover body 111 bottoms, and gas is filled with in the protection air cushion; When aerating device is air-breathing; because the gas pressure of protection air cushion one side is larger than the gas pressure of aerating device side; gas makes spool 2 be expressed to 113 places, protruding hole and plastic deformation occurs to block protruding hole 113, makes to protect the gas of air cushion side can not reflux, and realizes the purpose of unidirectional air guide.

When using the utility model, the extruding gasbag body, gas in airbag body can be extruded from Non-return air valve 5, in airbag body, air pressure is less than the outer air pressure of airbag body, thereby by foam 3 compressions, make the smaller volume of airbag body, when needs, when inflating in airbag body, as long as pin air inlet button 4, make airbag body be in communication with the outside, foam 3 expands, thereby makes the volume of airbag body become large until restore to the original state.

It is simple and reasonable for the utility model, designs ingeniously, is easy to assembling and produces, and can regulate the air bag size by gas in the increase and decrease air bag, the convenient use.

As described in the utility model embodiment, with other air bags for the helmet of the same or similar structure of the utility model, all in the utility model protection domain.
