The protection airbag comprises an airbag body 100, wherein the airbag body 100 is of an integrated structure, and the airbag body 100 comprises a back airbag 10, a head airbag 20, a front chest airbag 30 and a shoulder airbag 40 according to the part of a human body corresponding to the airbag body 100 in the working process. The back airbag 10 is arranged in the middle of the airbag body 100, the head airbag 20 is communicated above the back airbag 10, a plurality of first airbag columns 21 extend outwards from the head airbag 20 at intervals, and due to gaps existing among the first airbag columns 21, when the first airbag columns 21 are fixedly connected, the original planar head airbag 20 is rolled up to form a three-dimensional holding shape, so that the head is wrapped. The shoulder air bag 40 extends towards two sides along the connection part of the back air bag 10 and the head air bag 20, the position corresponds to the shoulder of a human body, a plurality of second bag columns 41 extend outwards from the end part of the shoulder air bag 40 at intervals, and because gaps exist among the second bag columns 41, when the second bag columns 41 are fixedly connected, the original plane air bag is rolled up to form a three-dimensional holding shape, so that shoulder joints can be completely wrapped. The arrangement of the shoulder air bags 40 does not influence the normal movement of a user, and when the user falls down, the emergency reaction of the user is to restrain the body and protect the user as much as possible, the shoulder joints are more prominent, the possibility of injury at the positions is higher, and the shoulder air bags 40 realize the protection of important positions. The front airbag 30 is connected between the shoulder airbag 40 and the head airbag 20, the shoulder airbag 40 is folded by the fixed connection of the second pillar 41, and the front airbag 30 connected to the shoulder airbag 40 is therefore folded, extends from the two sides of the back airbag 10 in a planar state, and is turned to the front of the back airbag 10, so that a three-dimensional wrapping posture for a human body is formed without other restrictions. In the invention, the air inlet 31 is arranged at the end part of the front thorax air bag 30, the end part of the front thorax air bag 30 corresponds to the position of the waist and the abdomen, the position of a human body is relatively soft, and the air bottle is arranged at the position without causing secondary injury to a user and influencing the normal movement of the user.

According to the invention, the airbag material is cut to form a planar airbag body 100, then the first airbag columns are fixedly connected with each other, so that the head airbag 20 forms a three-dimensional structure wrapping the head, then the second airbag columns are fixedly connected with each other, so that the front chest airbag 30 is folded to the front of the back airbag 10, the shoulder airbag 40 forms a three-dimensional structure wrapping shoulder joints, and the manufacturing of the three-dimensional protection airbag is completed. When the air bag type shoulder air bag is in work, the protective air bag is inflated from the air inlet 31, and after the shoulder air bag 40 is inflated and expanded, an accommodating space capable of accommodating a human body is formed between the front chest air bag 30 and the back air bag 10 which are connected to two sides of the shoulder air bag 40; the head airbag 20 is supported by inflation, and takes a posture of wrapping the head. The three-dimensional structure of the plane protection air bag is realized.

Further, in an embodiment of the present invention, the airbag body 100 includes two film layers, and the edges of the two film layers are cut and fixed by OPW, weaving or thermocompression. The film layer has good sealing performance, is not easy to leak gas after being inflated, and can provide enough buffering. Since the back of the user is flat, the back airbag 10 is configured as a ring-shaped airbag to protect the back. The annular back airbag 10 can integrally support the back and keep away from the ground, and the annular air bag has the advantages of small air consumption for a circle, quick air intake and capability of quickly protecting a user. When the user falls, the position that the head received to collide with easily is head circumference a week, and the overhead position receives the possibility of striking less, consequently for fully protecting the head, first bag post 21 is in head gasbag 20 both sides symmetry sets up. Therefore, after the first bag columns 21 are fixedly connected with each other, the first bag columns 21 can respectively correspond to the positions of the two sides of the skull and the frontal bone and the position of the sphenoid bone, the head is protected, and meanwhile the head cannot be excessively extruded after expansion, so that discomfort is caused to a user. The first bag column 21 is in a straight column shape after being inflated, however, the head of a human body is in an arc shape, in order to enable the first bag column 21 to form a shape which is more fit with the head after being fixedly connected with each other, the edge of the first bag column 21 is provided with a plurality of contraction openings 22, and two sides of each contraction opening 22 are fit and fixed. As the constrictions 22 are pinched, the first bladder post 21 bends into an arc to fit more closely to the head. Of course, in other embodiments of the present invention, the position and number of the first bladder columns 21 may be determined according to the size of the head airbag 20 and the thickness of the first bladder columns 21. A neck airbag 50 is also communicated between the head airbag 20 and the shoulder airbag 40. The neck gasbag 50 can form the support to the neck after aerifing, when the user fell down, because back gasbag 10, shoulder gasbag 40 and chest gasbag 30 all expand, increased the distance between head and the ground, under the inertia effect, behind the health contact ground, the head still can be strikeed to the direction on ground, head gasbag 20 protects the head, but the excessive removal of head can cause the injury to the neck, therefore this embodiment is in still the intercommunication has neck gasbag 50 between head gasbag 20 and the shoulder gasbag 40. When the neck airbag 50 inflates, the neck airbag supports and limits the neck, so that the neck cannot swing at a large angle, and the neck is protected.

In the invention, the front thoracic air bag 30 is folded by fixedly connecting a plurality of second bag columns 41 to enable the shoulder air bag 40 to form an arc-shaped structure wrapping shoulder joints, and in order that the front thoracic air bag 30 does not tilt excessively to be incapable of fitting the front chest after being inflated and expanded, the front thoracic air bag 30 extends outwards along the second bag columns 41 on the side, close to the head air bag 20, of the shoulder air bag 40. Because the second bag column 41 corresponds to the position of the front part of the shoulder joint, namely the second bag column is surely folded, and because the second bag column is fixedly connected with other second bag columns 41, the position of the second bag column is determined, even if the second bag column is inflated, the second bag column 41 can not be folded, and further, the chest air bag connected with the second bag column can not be tilted, thereby ensuring the fit to the human body. The middle part of the shoulder air bag 40 is provided with a compaction hole 42, and after the shoulder air bag 40 is folded, the compaction hole 42 corresponds to the position above the shoulder of a user. Due to the arrangement of the compaction holes 42, the position cannot be expanded excessively after inflation, the shoulder air bags 40 are spread towards two sides, and the shoulder air bags 40 are not attached.

Referring to fig. 3, 4 and 5, in order to further increase the protection range of the protection airbag, a hip airbag 60 is communicated with the lower portion of the back airbag 10, and the hip airbag 60 faces the hip position of the user. Since the back airbag 10 does not have a curvature to wrap both sides of the user, the hip airbag 60 connected to the back airbag 10 does not have the curvature, so that the protection range of the hip airbag 60 is small, and the hip of the user, which is more likely to be injured, cannot be protected. Therefore, in the present invention, the hip airbag 70 is connected to the end of the chest airbag 30, and the hip airbag 60 is detachably connected to the hip airbag 70. The front chest airbag 30 is folded forward due to the folding of the shoulder airbag 40, the hip airbag 70 connected with the front chest airbag 30 is folded to the front side of the user along with the front chest airbag 30, the hip airbag 60 is positioned at the rear side of the user, the hip airbag 60 is connected with the splicing line 61 corresponding to the hip airbag 70, and the hip airbag 70 naturally wraps the hips of the two sides of the user. Even if inflated, hip airbag 70 will only form a plane that fits the side of the user and will not diverge to either side, and further restraint of hip airbag 60 and hip airbag 70 is not required. The spliced structure enables the lower half portion of the protective air bag to form a geometric three-dimensional shape, so that the protective air bag is more attached to a human body, and the omnibearing protection of a user is guaranteed. In this embodiment, the hip airbag 60 is divided into a plurality of lateral airbag pillars 62 by first solid lines 63. That is, the buttock airbag 60 can form a radian in the direction perpendicular to the first solid pressing line 63 so as to match with the buttock curve, so that the buttock airbag is more fit and has a good protection effect. Preferably, the hip airbag 70 is divided into longitudinal airbag columns 71 by a second solid line 72. So that the hip air bag 70 can also form an arc in the direction perpendicular to the second solid pressing line 72 to match the arc of the hip, and at the same time, the longitudinal air bag column 71 can completely cover the hip bone, and the air inlet direction of the hip air bag 70 is consistent with the direction of the longitudinal air bag column 71, so that the hip air bag 70 can quickly inlet air, and the protection effect is improved.

The invention designs the plane airbag body 100, and the plane airbag naturally forms a three-dimensional form by cutting and splicing the plane airbag body 100, thereby realizing the all-round protection of a user.
