Description

Technical Field

[0001] The utility model belongs to the technical field of safety belts, in particular to a fall suspension safety belt. Background Art

[0002] Since the Industrial Revolution, with the development of industries like construction, mining, and power generation, working at heights has become an integral part of the industry. However, safety issues associated with working at heights have also arisen, with falls being one of the leading causes of casualties. To reduce the occurrence of such accidents, the design of fall protection equipment, particularly safety harnesses, has received widespread attention and development. Early safety harnesses primarily focused on waist straps, but in-depth research into the consequences of falls revealed that relying solely on waist straps for securement posed serious safety risks, such as the potential for spinal injuries. Consequently, full-body harnesses have gradually become mainstream, distributing the impact of a fall across multiple areas of the body, significantly reducing the risk of injury. In recent years, advances in materials science and in-depth research into ergonomics have resulted in improvements not only in safety but also in comfort and adaptability, such as the use of lighter and more durable materials and optimized structural designs.

[0003] Despite significant progress in the development of full-body harnesses, some shortcomings remain in practical application. First, traditional harnesses often have only a single attachment point. Due to significant individual variation, they are difficult to adapt to larger body types, resulting in some users not receiving optimal protection. Second, existing technologies lack a back net, causing discomfort due to prolonged back stress. Therefore, we propose a fall suspension harness. Utility Model Content

[0004] In response to the problems existing in the existing technology, the purpose of the utility model is to provide a fall suspension safety belt. By having two hanging points, a large hanging ring and a front chest hanging point, the safety of heavier workers is guaranteed. By having a back net, the pressure can be reduced and distributed during long-term work, making the workers more comfortable.

[0005] The utility model is achieved in this way: a fall suspension safety belt comprises a large lifting ring, two back leaning belts are connected to the large lifting ring, a back net is fixedly connected between the two back leaning belts, two front upper chest straps are connected to the large lifting ring, the front upper chest straps are connected to the front chest straps through connecting buckles, the ends of the front chest straps are folded and sewn into eye shapes and form front chest hanging points, the front lower chest straps are fixedly connected to the front chest straps, a long buckle belt is fixedly connected to the front chest strap on the right side, and a short buckle belt is fixedly connected to the front chest strap on the left side, and a stepped portion is provided on the large lifting ring.

[0006] Optionally, the front lower chest strap is connected to the front chest strap via a Velcro, and the Velcro is sewn to the front lower chest strap and the front chest strap respectively.

[0007] Optionally, a small Japanese-style buckle is connected to the buckle belt, and the end of the front chest strap passes through the small Japanese-style buckle to form a folding portion, and the folding portion is connected to a first hoop.

[0008] Optionally, an annular reinforcement stitching portion is provided on the buckle strap, and a first oblique Japanese-style buckle is connected to the buckle strap.

[0009] Optionally, a lower wrapping belt is connected between the two backrest belts, and the lower wrapping belt is connected to the backrest belt through an annular suture.

[0010] Optionally, a first Japanese-style buckle is connected to the lower portion of the front lower chest strap, and a second hoop is connected to the front lower chest strap.

[0011] Optionally, a second oblique Japanese-style buckle is connected to the backrest belt, and an upward label is provided on the upper part of the backrest belt.

[0012] Optionally, a reflective tape is fixedly connected to the upper portion of the rear belt, and a transparent film is respectively adhered to the reflective tape and the upward label.

[0013] Optionally, the large lifting ring is connected to a connecting belt via a first hook, and a buffer is connected to the connecting belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The design provides two lifting points: a large lifting ring and a chest lifting point, ensuring the safety of heavier workers. Specifically, the large lifting ring serves as the primary suspension point, bearing the majority of the weight; the chest lifting point provides additional support and stability, ensuring that in the event of an accidental fall, the weight is evenly distributed between the front and rear points, mitigating the risk of excessive force on a single point. This design not only increases the safety factor but also effectively prevents overall failure due to a single point failure, ultimately achieving a significant improvement in safety performance.

[0017] 2. By fixing the back net between the two backrest straps, the back net can reduce and distribute pressure during long-term work. The back net design can effectively expand the contact area and reduce local pressure. Especially during long-term suspension, it can significantly reduce the discomfort and potential injury risk caused by continuous pressure on the same area. At the same time, this design also improves air circulation and increases wearer comfort. As a result, this utility not only enhances the user experience, but also prolongs the user's tolerance time in high-altitude working environments, achieving the beneficial effect of improving work efficiency and comfort.
