[0026] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0027] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0028] Unless stated otherwise or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.

[0030] To provide more comprehensive protection and enhance the safety of protective clothing, the present invention provides a protective suit equipped with airbags. By providing a chest airbag, a back airbag, and a neck airbag, these airbags can provide specialized protection for key areas. The airbags are provided with a first edge and a second edge to enhance the reliability of the airbags during use and prevent air leakage. Furthermore, the second edges on opposite sides of the chest airbag and the back airbag can be bonded together via a first bonding portion and a second bonding portion. When inflated, these airbags form a double layer, capable of withstanding greater impact from a fall and enhancing the safety of the protective suit.

[0031] like Figure 1 As shown, the protective clothing airbag 10 of the present invention mainly includes three parts: a front chest airbag 11, a back airbag 12 and a neck airbag 13. There are two front chest airbags 11, which are used to protect the left front chest and the right front chest respectively; there are also two back airbags 12, which are used to protect the left back and the right back respectively. The neck airbag 13 is located between the front chest airbag 11 and the back airbag 12 and is used to protect the neck. The interior of the front chest airbag 11, the interior of the back airbag 12 and the interior of the neck airbag 13 are connected. By connecting the air inlet on the airbag and the port of the high-pressure gas cylinder, the front chest airbag 11, the back airbag 12 and the neck airbag 13 can be inflated. The effect after inflation is as follows. Figure 2 As shown. The location of the air inlet is not limited, and it can be set on the front chest airbag 11 as in the present embodiment, or it can be set on the back airbag 12. The airbag is composed of an inner layer and an outer layer. The material of the inner layer and the outer layer is preferably thermoplastic polyurethane (TPU). TPU has excellent elasticity and plasticity, can effectively deform when inflated, retain gas and absorb impact when subjected to force. The inner layer and the outer layer are bonded at the edge by hot melting or other methods to form a first edge 14. The first edge 14 extends along the edges of the front chest airbag 11, the back airbag 12 and the neck airbag 13. The area enclosed by the interconnected first edges 14 forms a closed cavity for filling with high-pressure gas, such as helium.

[0032] In order to improve the safety performance of the airbag, a second edge 15 is provided on the outside of the first edge 14 (i.e., toward the outside of the airbag) for the front chest airbag 11 and the back airbag 12. The second edge 15 can be formed by extending the inner layer and the outer layer at the first edge 14 outward and bonding them together. After the second edge 15 is provided, the firmness of the airbag edge can be improved to prevent air leaks. In addition, a plurality of first adhesive portions 16 and a plurality of second adhesive portions 17 are provided on the second edges 15 on opposite sides. Figure 3 As shown, in the uninflated state, by bonding the first adhesive portion 16 to the second adhesive portion 17, the left front chest airbag 11, the right front chest airbag 11, the left back airbag 12, and the right back airbag 12 can be folded to accommodate protective suits of different sizes. Furthermore, after folding, in the inflated state, two layers of airbags can be formed at key locations such as the left front chest, right front chest, left back, and right back, further enhancing the airbag's impact protection, resisting greater impact forces, and improving safety performance. For ease of manufacturing and to enhance the airbag's robustness, a second edge can also be provided at other locations on the airbag.

[0033] In this embodiment, the first adhesive portion 16 is a Velcro tab, and the second adhesive portion 17 is a Velcro tab. Velcro bonding is practical, convenient, and easy to manufacture. Preferably, the second adhesive portion 17 is longer than the first adhesive portion 16, allowing for flexible folding according to the size of the protective suit and adjusting the size of the airbags at various locations.

[0034] To better secure the airbags, ensure comfort, prevent twisting, and prevent them from expanding aimlessly between the inner and outer layers of the suit during inflation, notches 18 are provided at the free ends of the front and back airbags 11 and 12. With these notches in place, straps or other internal ties can be used to secure the airbags within the suit, thereby defining the positions of the front and back airbags 11 and 12. Compared to placing airbags haphazardly within the suit, this design notches not only provides comfort but also ensures the airbags' reliability during use, enhancing safety.

[0035] A shoulder airbag 19 is located between the front chest airbag 11 and the back airbag 12. In this embodiment, a notch 18 for limiting is also provided on the outside of the shoulder airbag 19, which can more effectively fix the airbag, make it comfortable to wear, and prevent the airbag from twisting.

[0036] The neck airbag 13 is located between the two shoulder airbags 19. The neck airbag 13 is similar to an inverted C-shape, with a connection port 131 at the bottom end, which is connected to the back airbag 12. The length of the top end is greater than the length of the bottom end, which can effectively protect the neck.

[0037] When the protective suit is a high-altitude work suit, for convenience, the safety rope needs to pass through the back. In order to take this requirement into account, the two back airbags 12 need to have a certain amount of space for expansion, rather than forcibly tearing the two back airbags 12 apart, so that a gap can be formed between the two back airbags 12 for the safety rope to pass through. Therefore, in this embodiment, an expansion portion 20 is provided between the neck airbag 13 and the back airbag 12. Specifically, the expansion portion 20 includes two deformation portions 21 that are symmetrically arranged on the left and right. The deformation portion 21 is similar to an inclined F-shape, including a connecting edge 211, an expansion edge 212 and a corridor area 213. The connecting edges 211 of the two deformation portions 21 are connected to form a V-shape. The expansion edge 212 is located at the first end of the connecting edge 211, and the corridor area 213 is a triangle and is located at the second end of the connecting edge 211. The expansion portion 20 of the above shape provides deformation space when the two back airbags 12 are separated.

[0038] In summary, the protective suit with an airbag in this embodiment provides focused protection for the chest, back, and neck. By providing a first edge and a second edge on the airbag, the airbag's reliability during use is improved, preventing air leakage. Furthermore, the first and second adhesive portions are bonded together on the chest and back airbags to form a two-layer airbag, which can withstand greater impact from a fall and enhance the safety of the protective suit.

[0039] The above embodiments are not exhaustive of the present invention, and there may be many other embodiments not listed. Any replacements and improvements made without violating the concept of the present invention are within the scope of protection of the present invention.
