Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection technology, and in particular to a fall protection device. Background Technology
[0002] With the increasing trend of population aging, accidental falls pose a serious threat to the lives and health of the elderly. Data indicates that more than 300,000 people die from falls worldwide each year, half of whom are over 60 years old. Currently, falls are the leading cause of injury-related death among people over 65, and the risk of injury or death from falls increases with age. The most serious consequence of a fall is fracture, with fractures easily occurring in vulnerable areas such as the hip joint, spine, and wrist. Hip fractures, in particular, are often referred to as "the last fracture of one's life." Statistics show that the mortality rate for hip fractures is as high as 20% to 30%.
[0003] With the development of sensor technology and airbag technology, innovative solutions for fall protection have emerged, giving rise to smart protective belts. Their core principle lies in using precise sensors to keenly monitor a person's fall. When the device detects a fall, the airbag quickly and automatically inflates and deploys, creating a buffer barrier between the body and the ground, effectively reducing the impact force and thus minimizing injury. However, existing smart protective belts on the market suffer from problems such as complex wearing and adjustment procedures and long airbag deployment times. Firstly, the complex structure and operation process deter users, especially the elderly and those with mobility impairments. Some existing products have cumbersome buckle designs that are difficult to use, and the length adjustment lacks flexibility, making wearing time-consuming and laborious. Furthermore, they are difficult to precisely adapt to the comfort needs of different body types, posing potential risks with long-term use. Secondly, there is the issue of airbag deployment performance. Due to the poor design of the inflation mechanism in existing technologies, the airbag deployment takes too long, making it difficult to respond in time during a fall and missing the golden opportunity for protection. This greatly weakens the protective effectiveness, leaving users exposed to high risks in emergency situations and unable to obtain comprehensive protection. Consequently, the practical value of smart protective belts is significantly reduced. Utility Model Content

[0010] As a further technical solution, the main control component is provided with a protrusion, which matches the insert, and the insert snaps into the protrusion to form a ring structure around the human body.
[0011] As a further technical solution, the hook and loop fasteners are horizontally arranged, and the length of the hook and loop fasteners is greater than the length of the loop fasteners, so that the hook fasteners can be adhered to different positions of the hook and loop fasteners.
[0012] As a further technical solution, the inflation mechanism is fixed on the sealed bag, and the position of the inflation mechanism is close to the airbag.
[0013] As a further technical solution, the inflation mechanism includes a gas cylinder and a gas cylinder bag. The gas cylinder is placed in the gas cylinder bag, which is equipped with a zipper.

Detailed Implementation
[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0029] Example 1
[0030] This utility model provides a fall protection device, such as Figure 1 and Figure 4 As shown, the fall protection device in this embodiment includes a waist belt body 100, an airbag 200, and an inflation mechanism 300, wherein... Figure 1 As shown, the waist belt body 100 includes a main control component 110 and an airbag storage bag 120. The side of the airbag storage bag 120 closest to the body is made of a stiff and breathable material, which improves the user's comfort. The airbag storage bag 120 specifically includes a compartment (not shown in the figure) and a cover bag (not shown in the figure). The airbag 200 is folded and stored inside the airbag storage bag 120. In this embodiment, the compartment and the cover bag are fixedly connected on one side, and strip Velcro is provided on the other side and both ends of the compartment and the cover bag. The airbag 200 is folded and stored in the compartment. In normal life (when not falling), the strip Velcro on the compartment and the strip Velcro on the cover bag are in an adhesive state. When the airbag inflates rapidly due to inflation, the strip Velcro on the compartment and the strip Velcro on the cover bag are unadhesive, thereby opening the airbag storage bag 120 and then the airbag 200 unfolds as a whole, providing cushioning protection for the user and reducing the injury caused by the user's fall.
[0031] In this embodiment, as Figure 4As shown, inside the airbag storage pouch, the inflation mechanism 300 is connected to the airbag 200, and a webbing 130 is fixed inside the airbag storage pouch 120. One end of the webbing 130 is connected to the main control component 110, and the other end of the webbing 130 is connected to an insert 140. Specifically, the middle portion of the webbing 130 is sewn and fixed inside the airbag storage pouch 120, specifically, the middle portion of the webbing 130 is sewn onto the airbag chamber, and both ends of the webbing 130 extend beyond the airbag storage pouch 120 to the outside of the airbag storage pouch 120. In this embodiment, as... Figure 2 As shown, the main control component 110 has a protrusion that matches the insert 140. The insert is connected to the protrusion by a buckle, forming a ring structure around the human body. The device can be worn by buckling, which is simple to operate and secure. It not only saves time to wear, but also effectively resists external pulling and friction during daily activities, ensuring that the device is always in a precise position. This greatly enhances the convenience and reliability of use and effectively avoids interference with the protective function due to frequent adjustments or accidental loosening.
[0032] In this embodiment, as Figure 2 As shown, hook and loop fasteners 131 are provided on both sides of the webbing 130, and as... Figure 3 As shown, a loop fastener 121 is provided on the outside of the airbag storage bag 120, on the side away from the body. Specifically, the loop fastener 121 and the hook fastener 131 are horizontally positioned, and the length of the loop fastener 121 is greater than the length of the hook fastener 131, so that the hook fastener 131 can be attached to different positions of the loop fastener 121 to obtain different wrapping lengths of the webbing 130. This allows for length adjustment of the fall protection device, with a large adjustable range, which can adapt to different waist sizes and avoid the feeling of tightness or looseness caused by size mismatch. This greatly improves wearing comfort and stability, laying a good foundation for long-term use.
[0033] In this embodiment, as Figure 5 As shown, the airbag 200 has several fixing holes 210 on its upper surface, and is fixedly connected to the airbag chamber by buttons. Specifically, one end of the button is fixedly connected to the airbag chamber, and the other end of the button passes through the fixing hole 210 and is tightly engaged to prevent the airbag 200 from falling off when it inflates and deploys. In this embodiment, as... Figure 4 As shown, the inflation mechanism 300 is fixed to the sealed bag, and its position is close to the airbag, ensuring that the airbag inflates rapidly in a very short time. This allows the airbag to deploy quickly, providing immediate and reliable fall protection for the user, and solves the problem of slow airbag deployment and reduced protective function of existing technologies. Figure 4 and 5As shown, the inflation mechanism 300 includes a gas cylinder 310 and a gas cylinder bag 320, with the gas cylinder 310 placed inside the gas cylinder bag 320, as... Figure 1 As shown, a zipper 321 is provided on the gas cylinder bag 320, which facilitates opening and closing of the gas cylinder bag 320. In this embodiment, the gas cylinder bag 320 is made of thick composite fabric, used for heat insulation, sound absorption, and shock absorption of the gas cylinder 310 inside the gas cylinder bag 320. Figure 5 As shown, the outlet of the gas cylinder 310 is connected to an inflation tube. One end of the inflation tube is connected to the outlet of the gas cylinder 310, and the other end is connected to the air inlet of the airbag 200, forming a closed airflow channel. In this embodiment, the gas cylinder 310 is connected to the main control component 110. The main control component 110 is used to monitor whether the user has fallen and to control the gas cylinder 310 to inflate the airbag. The above monitoring method is existing technology in the field. Specifically, in this embodiment, the main control component 110 is equipped with sensors and other components. The main control component is used to monitor whether the user has fallen. When the user is detected to have fallen, the main control component controls the gas cylinder to inflate the airbag. The sensor monitoring process is existing technology. This utility model does not improve the monitoring process, so it will not be described in detail.
[0034] The fall protection device mentioned in this embodiment operates on the following principle: The user adjusts the length of the fall protection device by changing the position of the hook-and-loop fastener 131 attached to the loop fastener 121 according to their own waist circumference. The adjustable range is large, accommodating different waist sizes. During wear, the main control unit monitors in real time whether a fall occurs. When the main control unit 110 detects a fall, the gas cylinder 310 inflates the airbag 200 through the inflation tube. The airbag 200 inflates, causing the strip fasteners on the airbag compartment and the sealing bag to unfasten, thus opening the airbag storage bag 120. The airbag 200 then deploys fully, providing cushioning protection and reducing injuries from falls.
[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
