Because the brim 22 is turned over, gas entering the protective device cannot enter the brim 22 at the first time, even if a small amount of gas enters the brim 22, the brim 22 cannot be separated from the top of the hood 21 and still is in a turned state under the fixation of the fixing part 30, the gas smoothly enters the hood 21 part at the moment, the hood 21 part is propped up to cover the head, the gas entering the brim 22 is increased along with the increase of the air inflow, the brim 22 is propped outwards, the fastening force of the female part 31 and the sub-part 32 is overcome by the force generated by expansion, the fixing part 30 is opened, the brim 22 extends forwards along the natural expansion direction of the air bag 10 and the face direction, and the whole head is protected. For making protector can in time open when the people is about to fall down, form the protection to the head, gasbag 10 is connected with air inlet 11, air inlet 11 department is connected with gas generator, gas generator is connected with the response chip. When the response chip detects the human body and is about to fall down, the response chip starts gas generator, and gas generator fills the gas body in to gasbag 10 fast to before falling down, the human body formation protection prevents to fall down the injury that causes the human body. The air inlet 11 in this embodiment is disposed at one side of the lower portion of the airbag 20, but in other embodiments of the present invention, the position of the air inlet 11 may be selected according to actual needs.

In the first embodiment of the present invention, the fixing portion 30 is a snap, the female portion 31 of the snap includes a panel and a female button, the panel and the female button clamp the top of the hood 21, the sub-portion 32 of the snap includes a sub-button and a foot, and the sub-button and the foot clamp the top of the hood 22, the hood 20. The female part 31 and the sub-part 32 of the snap fastener are respectively connected with the cap leather 20 only, so that the inflation of the air bag 10 is not influenced, the air bag 10 can expand and break open the snap fastener, and the opening of the cap peak 22 is realized. In other embodiments of the invention, the fixing portion 30 may be a suture button, a female portion 31 of the suture button is sewn to the cap skin 20 on the top of the hood 21, and a sub-portion 32 of the suture button is sewn to the cap skin 20 on the top of the visor 22. The female portion 31 and the sub-portion 32 are convenient to buckle, and the airbag 10 can expand the female portion 31 and the sub-portion 32 to ensure that the visor 22 is partially opened. In other embodiments of the present invention, the fixing portion 30 may also be a snap fastener similar to the snap fastener.

In order to facilitate the connection of the protection device of the present invention to the upper garment, the lower portion of the cap skin 20 is provided with a connector 23 connected to the upper garment. Specifically, the connecting member 23 is a zipper, a hook and loop fastener, a button or a snap fastener.

The inner container 12 is good in sealing performance and used for inflation, can bear certain air pressure, is large in structural strength of the outer layer 13, can bear friction with the outside and internal strong pressure, protects the inner container 12, and therefore effectively improves anti-friction and anti-collision strength to the outside. And the inner bag 12 is because the elasticity of self is aerifyd the back inflation, and the inflation size of outer 13 is less than the inflation size of inner bag 12, therefore inner bag 12 can prop up outer 13, and when inner bag 12 aerifys the inflation and expands and reach the limit of outer 13, because the restriction inner bag 12 of outer 13 can't continue the inflation for inner bag 12 can not the excessive inflation, and because the parcel of outer 13 guarantees that each part inflation degree of inner bag 12 is even, the swell phenomenon can not appear. At this moment, the outer layer 13 is attached to the inner container 12, the outer layer 13 becomes hard due to uniform compression, support is provided for the inner container 12, and when the protective airbag 10 is compressed, the inner container 12 and the outer layer 13 bear pressure jointly, so that sufficient buffering is guaranteed to be provided, and the head is protected.

Referring to fig. 3, the balloon 10 of the present invention is a wrap-around balloon, so that it can be formed into a shape to wrap the head forward from the hindbrain. The encircling type air bag comprises a main air channel 14 and claw-shaped air bag columns 15 extending towards two sides of the main air channel 14, wherein the claw-shaped air bag columns 15 are symmetrically arranged along the central axis of the main air channel 14. Furthermore, the diameters of the air bags 10 in the claw-shaped air bag columns 15 are different, so that the bending positions and the bending angles of the air bags 10 are different when the head is wrapped, and the purpose that the head is wrapped by the air bags 10 after being inflated is achieved better. When the gas generator generates gas, the gas enters the air bag 10 from the main air passage 14, the gas rapidly flows into the claw-shaped air bag columns 15 on the two sides, the claw-shaped air bag columns 15 are inflated to wrap the head of a human body under the limitation of the cap skin 20, meanwhile, the cap brim 22 is turned over to protect the head of the human body from all directions of the back, the upper part, the front and the two sides, the claw-shaped air bag columns 15 wrap the head like claws, and the protection area is large and comprehensive. Because the post of gasbag 10 is straight column shape after aerifing, in this embodiment, for making the gasbag 10 post can form the arc structure in order to wrap up the head, first gasbag post 151 and second gasbag post 152 side are provided with a plurality of angle of restrainting, guarantee that the gasbag 10 post can form the shape of laminating head.

Further, two flow guide lines 16 are arranged in the encircling type air bag, and the main air passage 14 is divided into three air inlet passages 17 by the flow guide lines 16. On one hand, the main air passage 14 is divided into a plurality of parts by the diversion line 16, so that the head of the air bag 10 cannot be wrapped by the column of the air bag 10 due to excessive bulging of the main air passage 14, and on the other hand, the air inflow of the air bag 10 is reduced, so that the inflating speed of the air bag 10 is higher. And the arrangement of the diversion line 16 also provides a connecting position for the air bag 10 and the cap skin 20, so that the connection between the air bag 10 and the cap skin 20 is more stable, and the shape of the hood 21 is maintained. In this embodiment, the two flow guiding lines 16 are arranged in a shape of a Chinese character 'ba', so that the air inlet channel 17 in the middle is gradually narrowed. Therefore, the gas flows in from the main air passage 14, passes through the splayed flow guide line 16, and then gradually narrows, increases the pressure and increases the speed under the condition that the gas pressure is not changed, so that the gas continuously flows forwards after being pressurized and accelerated by the splayed flow guide line 16, and the rapid expansion of the tail end air passage is facilitated.

In order to fully protect the head without squeezing the head, in the present embodiment, the claw airbag pillars 15 on each side of the main airway 14 include a first airbag pillar 151 and a second airbag pillar 152 corresponding to the position of the skull and the forehead, a third airbag pillar 153 corresponding to the sphenoid, and a fourth airbag pillar 154 corresponding to the mandible. The first, second and third air bag columns 153 form the omnibearing protection to the upper skull, the fourth air bag column 154 forms the protection to the lower jaw bone, because the third air bag column 153 and the fourth air bag column 154 are expanded and then protrude outwards, the position of the ear is left between the third air bag column 153 and the fourth air bag column 154, so that the ear is not extruded, and the expanded third air bag column 153 and the expanded fourth air bag column 154 can ensure that the position of the ear does not contact the ground, and also form the protection to the position of the ear.
