Description

Technical Field

[0001] This utility model relates to a fall protection suit, and more particularly to a split-type airbag structure based on the fall protection suit. Background Technology

[0002] Fall protection suits are protective equipment that provide all-round protection for workers when working at a height of 2 meters or more. They mainly consist of a protective vest, airbags, an inflation cylinder, and a fall protection sensor. When a worker accidentally falls during work, the fall protection sensor detects the fall and drives the inflation cylinder to inflate the airbag inside the protective vest. The inflated airbag then wraps around the worker's body, thus cushioning the impact force during the fall and achieving the protective function.

[0003] There are two existing methods for installing airbags in fall protection suits. The first method involves sewing the airbag directly into the inner layer of the protective vest, with gas cylinder installation pockets and inflation ports on both sides of the back of the suit near the shoulders and neck. This allows the airbag to inflate simultaneously from both gas cylinders when a worker falls, inflating along with the suit to envelop the worker. The advantage of this structure is that the airbag's position within the suit is relatively fixed, maintaining a flat position and completely covering critical areas, thus ensuring the effective envelopment and protection of the worker after inflation. However, its drawback is that if the airbag develops scratches or punctures after long-term use, the worker cannot remove and replace it individually, increasing the long-term maintenance costs of the fall protection suit.

[0004] To address the aforementioned shortcomings, the second installation method involves creating a separate structure for the protective vest and airbags, which are then used together. Specifically, several pockets are cut into the inside of the protective vest to hold the airbags, and each airbag is inserted into one of these pockets. When the airbags need to be removed later, the worker can simply pull them out of the pockets, separating them and facilitating airbag replacement. While this structure allows for individual airbag replacement compared to the first, the lack of corresponding restraints after the airbags are inserted into the pockets makes them prone to wrinkling and shifting during use due to worker movement. This can obstruct inflation, preventing certain parts of the airbag from inflating properly and creating a safety hazard. Furthermore, using Velcro or snap fasteners to restrain the corners of the airbags is problematic. Firstly, these fasteners are located inside the protective vest, increasing the difficulty of flattening and securing the airbags. Secondly, the airbags are prone to slipping under stress during subsequent use, resulting in an unsatisfactory fixation.

[0005] Therefore, the existing split-type airbag structure used in fall protection suits cannot guarantee the positioning and flattening of the airbag during use. Utility Model Content

[0006] The purpose of this invention is to provide a split-type airbag structure based on a fall protection suit. It enables the individual disassembly of the airbag while ensuring its fixation and flattening during use.

[0007] The technical solution of this utility model is as follows: A split-type airbag structure based on a fall protection suit, comprising a split-type fall protection suit and an airbag. The fall protection suit includes a protective vest and an inner lining, which are nested together and connected to each other. The inner lining includes a front lining and a back lining, which are connected to each other by shoulder straps. The inner sides of both the front and back linings are provided with placement cavities for accommodating the airbags, and several mounting ports are distributed around the placement cavities. The airbag includes a first airbag segment located outside the placement cavity. Multiple second airbag segments are connected around the first airbag segment. Each second airbag segment extends into a placement cavity. Several connecting pieces are distributed on both sides of the second airbag segments. The ends of the connecting pieces extend to the outside of the inner lining through the mounting ports and are detachably connected to a limiting component. The limiting component and the surface of the inner lining are connected to each other by a first snap fastener.

[0008] In the aforementioned split-type airbag structure based on a fall protection suit, the connecting piece has a circular hole in the middle, and the limiting component includes a split screw head and a nut. One end of the screw head is connected to a first snap, and the other end of the screw head passes through the circular hole and is threaded to the nut.

[0009] In the aforementioned split-type airbag structure based on a fall protection suit, the outer diameter of the screw head is larger than the length of the mounting port.

[0010] In the aforementioned split-type airbag structure based on a fall protection suit, there are two front linings arranged side by side on the left and right sides of the protective vest, and one side of the front lining is connected to the protective vest via a zipper; the top of the back lining is hung on the back of the protective vest via a hanging hook.

[0011] In the aforementioned split-type airbag structure based on a fall protection suit, the front and rear linings are connected to each other on both sides by buckle straps. The top of both sides of the protective vest is provided with arm holes, and the lower end of the arm holes is provided with a covering layer. One end of the covering layer is fixedly connected to the protective vest, and the other end of the covering layer is connected to the protective vest via a second snap.

[0012] In the aforementioned split-type airbag structure based on a fall protection suit, a third airbag is connected to the outside of the first airbag split, and the top of the protective vest is provided with a neck pocket that matches the third airbag split.

[0013] Compared with the prior art, this utility model has the following characteristics:

[0014] (1) This utility model separates the existing one-piece fall protection suit into a protective vest and an inner lining structure, so that the inner lining can be removed from the protective vest and used to install the airbag; on this basis, the airbag is connected by a limiting component after being inserted into the placement cavity. On the one hand, the limiting component can be extended to the outside of the placement cavity, which facilitates the fixing operation of the operator; on the other hand, the limiting component and the installation port can be used to limit the airbag after it is deployed, so that the connecting pieces on both sides of the second airbag are blocked by the limiting component and cannot be retracted back into the placement cavity from the installation port. This effectively prevents the airbag from wrinkling and shifting during use, and improves the fixing and flattening effect of the airbag in this utility model.

[0015] (2) By combining the protective vest and the liner, the liner and the airbag can be hidden inside the protective vest, thus using the protective vest to wrap and protect the liner and the airbag; and when the protective vest is worn or torn during use, the workers can replace the protective vest separately, further reducing the later maintenance cost of the fall protection suit.

[0016] (3) By connecting the two sides of the front and back lining with buckle straps, and connecting the two sides of the protective vest with the covering layer, the covering layer can wrap and cover the buckle straps on the inside to prevent them from getting caught on external facilities during use. On the other hand, it can also wrap the body of the worker in the non-inflated state, thus preventing the fall protection suit from loosening and shaking. When the airbag is inflated, the second snap will be released and the covering layer will be released. At the same time, the buckle straps will achieve their limiting function after being straightened, effectively preventing the fall protection suit from loosening and falling off.

[0017] Therefore, this utility model can achieve the function of individual airbag disassembly while ensuring the airbag is fixed and flattened during use. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] Example. A split-type airbag structure based on a fall arrest suit, configured as follows: Figure 1 As shown, the device includes a split-type fall protection suit and an airbag. The fall protection suit includes a protective vest 1 and an inner lining. The inner lining and the protective vest 1 are nested together and connected to each other. The inner lining includes a front lining 2 and a back lining 3, which are connected to each other by a shoulder strap 4. The shoulder strap 4 is located on the inner side of the shoulder of the protective vest 1 after the inner lining is installed, and can be glued to the protective vest 1 by Velcro. The inner sides of the front lining 2 and the back lining 3 are provided with placement cavities 5 for accommodating airbags. Several installation ports 501 are distributed around the placement cavities 5. The airbag includes a first airbag segment 6 located outside the placement cavity 5. Several second airbag segments 7 are connected around the first airbag segment 6. Each second airbag segment 7 extends into a placement cavity 5. Several connecting pieces 8 are distributed on both sides of the second airbag segment 7. The ends of the connecting pieces 8 extend to the outside of the inner lining through the installation ports 501 and are detachably connected to a limiting component. The limiting component and the surface of the inner lining are connected to each other by a first snap 9.

[0028] The protective vest 1 is equipped with a gas cylinder and a fall protection sensor on the back of the neck and shoulders. The nozzle of the gas cylinder passes through the protective vest 1 and is connected to the first airbag split 6.

[0029] There are two of each of the first airbag components 6 and the second airbag components 7, which are used to protect the front and back of the worker's torso after inflation.

[0030] The protective vest 1 and the back liner 3 are both provided with elongated openings in the middle to allow the second airbag detachment 7 to inflate normally.

[0031] The connecting piece 8 has a round hole in the middle. The limiting component includes a split screw head 10 and a nut 11. One end of the screw head 10 is connected to the first snap button 9, and the other end of the screw head 10 passes through the round hole and is threaded to the nut 11.

[0032] The outer diameter of the screw head 10 is greater than the length of the mounting port 501.

[0033] The number of front linings 2 is two, and they are arranged side by side on the left and right sides of the protective vest 1. One side of the front lining 2 is connected to the protective vest 1 via a zipper 12. The top of the back lining 3 is hung on the back of the protective vest 1 via a hanging hook.

[0034] The protective vest 1 has a double zipper structure at the middle opening. The outer zipper is used to connect the two protective vests 1 together after being zipped up and to wrap the workers. The inner zipper 12 is used to connect the inner lining.

[0035] The front liner 2 and the rear liner 3 are connected to each other on both sides by buckle straps 13. The buckle straps 13 are conventional buckle straps with D-rings. The operator can adjust the length of the straps by using the D-rings, so that the buckle straps 13 can be fully straightened after the airbag is inflated and achieve the function of limiting the fall protection suit. The protective vest 1 has arm holes on the top of both sides. The lower end of the arm holes is provided with a covering layer 14. One end of the covering layer 14 is fixedly connected to the front edge of the protective vest 1, and the other end of the covering layer 14 is connected to the back edge of the protective vest 1 via a second snap 15.

[0036] The first airbag unit 6 is externally connected to a third airbag unit 16. The top of the protective vest 1 is provided with a neck pocket that matches the third airbag unit 16. The third airbag unit 16 is used to protect the back, shoulders and neck of the worker after inflation.

[0037] The first airbag component 6, the second airbag component 7, and the third airbag component 16 are interconnected to form an integrated structure.

[0038] The working principle of this utility model is as follows: When using this utility model, each of the second airbag segments 7 is first inserted into the placement cavities 5 of the front liner 2 and the rear liner 3 respectively. Then, the connecting piece 8 on the second airbag segment 7 extends out from the mounting port 501 on the side wall of the placement cavity 5 and is connected to the screw head 10 and nut 11. After the screw head 10 and nut 11 are connected, they can limit the connecting piece 8, so that the connecting piece 8 cannot retract back into the placement cavity 5 from the mounting port 501 due to the obstruction of the two. This achieves the flattening and fixing of the second airbag segment 7 in the placement cavity 5.

[0039] After the airbags and lining are connected, the worker secures the lining with the airbags to the inside of the protective vest 1 using zippers 12 and hanging loops. The third airbag assembly 16 is then fastened into the neck pocket at the top of the protective vest 1, allowing the two to connect and form a one-piece fall protection suit. When the worker wears the fall protection suit, the front lining 2 and the back lining 3 are first connected on both sides using buckle straps 13. Then, the edges of the front and back sides of the protective vest 1 are connected using the covering layer 14 and the second snap 15. This allows the covering layer 14 to restrict the movement of the protective vest 1 and the lining under normal conditions, ensuring they fit snugly against the worker's torso. Simultaneously, the buckle straps 13 are in a bent and relaxed state under this condition and are wrapped inside by the covering layer 14. When the airbag is inflated, the front liner 2 and the rear liner 3 bulge outwards, exerting an outward pulling force on the covering layer 14 from both sides. This causes the second snap button 15 to disengage under the pulling force, releasing the limiting function of the covering layer 14 on the fall protection suit. After the second snap button 15 disengages, the buckle strap 13 gradually changes from a bent and loose state to a taut and straight state as the front liner 2 and the rear liner 3 inflate, thus replacing the covering layer 14 to limit the fall protection suit on both sides, ensuring that the fall protection suit fits tightly against the worker's torso when inflated, guaranteeing its protective effect.
