Abstract

PURPOSE:To reduce the weight of the safety belt by directly connecting a life line to a body belt, passing this body belt into a moving stopper plate and rotatably holding the life line by means of this moving stopper plate. CONSTITUTION:A ring is formed by stitching the life line 1 and the body belt 3 is passed into the ring 2. The life line is then directly connected to the body belt 3. Further, the body belt 3 is passed into the moving stopper plate 4 and the life line 1 is rotatably held by the moving stopper plate 4. The life line1 is a slender belt of double structures which are linearly arranged with high tensile yarn of a synthetic fiber, such as alamid fibers in the longitudinal direction and are woven with synthetic fibers having excellent weatherability, wear resistance and dyeability on the outer peripheries thereof to protect the core body. This belt has a stitched part 5 and a hook 6. The body belt 3 has a stitched part 7 and a buckle 8. As a result, the weight of the safety belt is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety belt.

[0002]

2. Description of the Related Art Conventionally, the lifeline has been connected to a metal connecting ring, and the trunk belt has been connected and integrated through the connecting ring (safety belt standard) (Ministry of Labor).

[0003]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of reducing the weight of a safety belt.

[0004]

According to the present invention, the safety belt is characterized in that the lifeline is directly connected to the trunk belt, the trunk belt is passed through the detent plate, and the lifeline is rotatably held by the detent plate. Will be provided.

Further, according to the present invention, there is provided a connecting ring for a safety belt, characterized in that synthetic fiber yarns are woven together or wound and polymerized and bonded in an annular shape.

Description of Embodiments Embodiments of the present invention will be described below.
FIG. 1 shows an embodiment of the present invention. In this embodiment, except for the connecting ring, the lifeline 1 is attached to form the ring 2 and the trunk belt 3
The lifeline 1 was directly connected to the trunk belt 3 through the ring 2. Further, the trunk belt 3 is passed through the detent plate 4, and the life line 1 is rotatably held by the detent plate 4. This made the safety belt lighter. . Lifeline 1 protects the core body by arranging synthetic fiber high-tensile yarn such as aramid fiber linearly in the longitudinal direction on the core body and weaving the outer periphery thereof with synthetic fiber with excellent weather resistance, abrasion resistance, and dyeability. Width of double structure 25
It is a narrow belt having a thickness of less than or equal to mm and a thickness of less than or equal to 2.5 mm, and has an attachment portion 5 and a hook 6. The torso belt 3 is the adhesion part 7
And with a buckle 8. According to the standards of the Ministry of Labor safety zone, the conventional connecting ring is made of iron and is a seamless ring with a strength of 1150 kg or more. The weight of this ring is about 60 g, which occupies 8% of the weight of the safety belt.

In the detent plate 4 of FIG. 2, the ring 2 of the lifeline 1 is arranged between a pair of projecting walls 9 formed on the detent plate 4, and the trunk belt 3 is attached to the belt hole 1 of the detent plate 4.
0, 11, through the ring 2 of the lifeline 1, and through the belt holes 12, 13 of the detent plate 4. In the detent plate 4 of FIG. 3, the ring 2 of the lifeline 1 is pushed through the gap 14 of the projecting wall 9 between the projecting walls 9 and the trunk belt 3 is passed through the ring 2 of the lifeline 1. In the detent plate 4 of FIG. 4, the auxiliary ring 15 is passed through the ring 2 of the lifeline 1, the trunk belt 3 is passed through the ring 2 of the lifeline 1, and the auxiliary ring 15 and the detent plate 4 are fixed by the trunk belt 3.

In the embodiment shown in FIG. 5, the body belt 3 is passed through the connecting ring stopper 16 and the connecting ring 17, and the lifeline 1 and the body belt 3 are connected by the connecting ring 17. In the connecting ring 17 of FIGS. 6 and 7, a synthetic fiber high-strength yarn 18 such as aramid fiber is wound and polymerized in a hollow ring 19 made of a synthetic resin and having a U-shaped cross section as many times as necessary strength is obtained, The high-strength yarn 18 was adhered with an adhesive and then covered with a cover 20 made of synthetic resin. This made the safety belt lighter. In the connecting ring 17 of FIGS. 8 and 9, synthetic resin high-strength yarn such as aramid fiber is arranged as a core in a straight line in the longitudinal direction,
The outer circumference is protected and woven with a thread having excellent weather resistance such as tetoron fiber and has a width of 10 mm or more, 25 mm or less, and a thickness of 0.5 mm or more, 2.5 mm or less, and forms an annular shape, and part of the layers is overlapped. They were put together and attached with a sewing thread.

[0009]

As described above, the present invention can reduce the weight of the safety belt and achieve the intended purpose.
