Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-altitude operation safety technology, and in particular to a high-stability, high-strength polypropylene fiber integrated lock safety belt. Background Technology
[0002] Safety belts are necessary for working at heights, primarily to protect workers' lives and prevent falls. At heights, loss of balance or external forces can easily lead to falls. Safety belts provide immediate braking and support, preventing direct impact and reducing injury. Furthermore, safety belts enhance workers' sense of security, allowing them to focus on their work and improving efficiency.
[0003] Seat belts generally include three-point and five-point structures. However, current technology typically only offers either a three-point or five-point structure. Three-point seat belts, which only restrain the shoulders and waist while lacking leg support, may cause occupants to slip out during high-impact situations, resulting in insufficient safety and poor protection for children or smaller passengers. While five-point seat belts provide more comprehensive restraint, they are complex to wear, inconvenient to use, and less comfortable, making them unsuitable for everyday situations. These two types of seat belts exhibit significant limitations in terms of applicability and convenience. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing seat belts, which typically only have a three-point or five-point structure. Three-point seat belts, which only restrain the shoulders and waist while lacking leg support, may cause occupants to slip out during high impacts, resulting in insufficient safety and poor protection for children or smaller passengers. While five-point seat belts offer more comprehensive restraint, they are complex to wear, inconvenient to use, and uncomfortable, making them unsuitable for everyday situations. These two types of seat belts have significant limitations in terms of applicability and convenience. Therefore, this invention proposes a high-stability, high-strength polypropylene fiber integrated locking seat belt.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-stability, high-strength polypropylene filament integrated lock safety belt includes a first shoulder strap, a second shoulder strap, a waist loop, and a rear securing strap. Rear securing rings are fixedly installed at both ends of the rear securing strap. One rear securing ring is fixedly installed on the side of the first shoulder strap, and the other rear securing ring is fixedly installed on the side of the second shoulder strap. A suspension ring is rotatably connected to the top center of the rear securing strap. Bottom loops are fixedly installed at the bottom of both the first and second shoulder straps. Switching components are provided on the front sides of the first and second shoulder straps to switch the entire safety belt structure from a "three-point safety structure" to a "five-point safety structure."
[0007] Optionally, the first shoulder strap and the second shoulder strap are provided with an anti-slip auxiliary strap on the side away from the rear fixing strap, and an anti-slip buckle is fixedly provided at one end of the anti-slip auxiliary strap.
[0008] Optionally, the switching component includes a storage strap, a crotch strap, and a tensioning strap, and the bottom rings on the front sides of the first shoulder strap and the second shoulder strap are both fixedly provided with crotch straps.
[0009] Optionally, a hip buckle is fixedly provided at the bottom of the hip strap, and tension straps are fixedly provided at the bottom rings on the rear sides of the first shoulder strap and the second shoulder strap.
[0010] Optionally, an auxiliary ring is fixedly provided on the top of the front side of both the first shoulder strap and the second shoulder strap, and a storage strap is fixedly provided on the side of the auxiliary ring.
[0011] Optionally, the four bottom rings are collectively fitted with a waist belt, and one end of the waist belt is fixedly provided with a waist buckle.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] 1. The main structure of this utility model includes a first shoulder strap, a second shoulder strap, and a waist belt. The bottom of the first shoulder strap and the second shoulder strap are provided with a switching component. The switching component allows the entire seat belt to switch between a three-point safety structure and a five-point safety structure. It has the advantages of wide applicability and convenient operation. It can meet the needs of comfort and simplicity in daily driving, and provide more comprehensive fixation protection in high-safety scenarios, which greatly improves the multifunctionality and practicality of the seat belt.
[0014] 2. When switching from a five-point safety structure to a three-point safety structure, this utility model can store the additional structure on the five-point safety structure into the sides of the first and second shoulder straps, maintaining the simplicity of the seat belt, avoiding the impact of additional structures on riding comfort, reducing wear and interference of exposed parts, improving the aesthetics and durability of the product, and making it easier for users to operate and store, thus improving the overall user experience.
