DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0021] The invention will be further illustrated in more detail with reference to the accompanying drawings and embodiments. It is noted that, the following embodiments only are intended for purposes of illustration, but are not intended to limit the scope of the present invention.
[0022] As shown in FIG. 1 and FIG. 4, a safety airbag for human body protection includes an upper airbag 1 and a lower airbag 2. The upper airbag 1 is used for protecting an upper part of the human body, and the lower airbag 2 is used for protecting the lower part of the human body, thereby providing full protection for the human body. The upper airbag 1 includes a back airbag 12 and a head airbag 13 extending laterally from back airbag 12, an upper air inlet is provided on a lower portion of the back airbag 12, the back airbag 12 protects the back and the vertebrae, and the head airbag 13 is extended laterally from the back airbag 12, such that not only the head but also the neck can be protected. In order to ensure that the head airbag 13 is further fitted to the head shape, the head airbag 13 laterally extending from the back airbag 12 is configured as U-shaped. The upper airbag 1 is T-shaped after folding. The lower airbag 2 includes a waist airbag 22 on a lower portion of which the lower air inlet 21 is provided, and a hip airbag 23 extending downward from the waist airbag 22 to a knee, thus, the lumbar bone, the hip bone, the sacrum, the tail bone and the femur are further protected. After the lower airbag 2 is unfolded, the waist airbag 22 is fitted to protect the waist, and the hip airbag 23 is opened outwards after inflation. The waist airbag 22 is folded, the hip airbag 23 is wound towards the waist airbag 22, and the waist airbag 22 is superposed on the hip airbag 23.The lower airbag 2 is folded as a waistband shape, and the safety airbag after folding occupies a small space and thus can be conveniently used with the belt and the strap, etc., and the daily appearance will not be affected. When inflating, the folded waist airbag 22 is rapidly inflated and unfolded, and the lower storage device of the lower airbag 2 is broken down at the fastest speed, then the hip airbag 23 and the fixing bands 24 are rapidly unwound and unfolded toward the hips, and the hips and hip bone are protected comprehensively. To ensure that the hip airbag 23 is fully fitted to the lower part of the human body, fixing bands 24 are connected at two sides of the lower end of the hip airbag 23, and the free ends of the fixing bands 24 are connected by a snap 25, and when the snap 25 is buckled up, the hip airbag 23 and the fixing bands 24 surround the legs. When folding, the fixing bands 24 are protruded from the lower airbag 2, and form a circle with the folded lower airbag 2. The hip airbag 23 is arc-shaped and surround the hips and legs, thereby providing full protection for the back and sides of the hips and legs. The upper air inlet 11 is in fluid communication with the lower air inlet 21, and the upper airbag 1 and the lower airbag 2 are simultaneously inflated by an inflation device 3, and the airbag can be quickly unfolded to provide comprehensive protection for the human body. In order to ensure the protection effect of the airbag, the head airbag 13 has a thickness of 40-80 mm after inflation, the back airbag 12 has a thickness of 80-100 mm, a length of 500-800 mm, and a width of 350-500 mm after inflation. The waist airbag 22 and the hip airbag 23 have a thickness of 40-80 mm after inflation. The length of the waist airbag 22 is less than the length of the hip airbag 23, and the hip airbag 23 is extended from the hips to the knee, thereby effectively protecting the hips and legs of the human body, to prevent the user from being injured after falling down. The waist airbag 22 has an arc-shaped structure fitted to the human body after inflation, and surround the waist. The hip airbag 23 includes a plurality of columnar airbags. Because the waist airbag 22 is arc-shaped, when inflated, the hip airbag 23 is expanded outwards to form a skirt structure, and is further bound by the fixing bands 24, thereby expanding the protection range.
[0023] As shown in FIG. 2 and FIG. 3, when the upper airbag 1 is not inflated, the back airbag 12 is folded along a center line thereof, and the head airbag 13 is wound towards the back airbag 12, thereby the upper airbag 1 is completely folded in the vertical direction, and the wound head airbag 13 is downwards folded towards the back airbag 12 until the head airbag 13 is completely folded in the length direction, and the folded safety airbag is elongated and does not affect the appearance of wearing. When inflated, the air is introduced from the upper air inlet 11 on a lower portion of the back airbag 12, and the folded back airbag 12 and the head airbag 13 are rapidly inflated and unfolded to break down the upper storage device of the upper airbag 1 at the fastest speed. Then, the head airbag 13 is rapidly extended and spread laterally from head to fully wrap the head, thereby providing a comprehensive protection for the back, neck and head.
[0024] As shown in FIG. 1, the inflating device 3 is further connected with a trigger button 31 and a gravity sensor 32. The inflating device 3 is opened automatically upon receiving a signal of falling from the gravity sensor 32, or the inflating device 3 is manually activated by means of the trigger button 31 when a coming falling is felt by the human body. Thus, it is ensured that the safety airbag can be opened in various ways before the human body is injured.
[0025] In order to inflate the upper air bag 1 and the lower air bag 2, at least one upper air inlet 11 and at least one lower air inlet 21 are provided. In the embodiments of the invention, two upper air inlets 21 and two lower air inlets 21 are provided so that the inflation devices 3 are arranged conveniently. The inflation devices 3 are located at two sides of the two upper air inlets 11 and the lower air inlets 21, respectively.
[0026] The above description is only preferred embodiments of the present invention and not intended to limit the present invention, it should be noted that those of ordinary skill in the art can further make various modifications and variations without departing from the technical principles of the present invention, and these modifications and variations also should be considered to be within the scope of protection of the present invention.
