The bent portion 18b is bent and extended convexly from one end portion of the base portion 18a to the other end portion of the base portion 18a in a direction away from the base portion 18 a. The curved portion 18b is curved in a smooth curve. The base portion 18a is sandwiched between the pair of intersecting rear shoulder belt portions 12b and the fixed plate 16, and is attached thereto.

Fig. 2 shows a chest strap 20 as a connecting strap and a part of a pair of shoulder straps 12. Fig. 2 shows the chest band 20 as viewed from the front. Fig. 2 shows a state in which the shoulder belt 12 of the harness 10 is hooked on the shoulder of the wearer.

The chest band 20 includes a first chest band portion 20a as a first coupling band portion, a second chest band portion 20b as a second coupling band portion, and a buckle 20c as a coupling member. The first chest strap part 20a is connected to one of the shoulder straps 12. The second chest strap part 20b is connected to the other shoulder strap 12. The buckle 20c includes a buckle main body 20d as a first end portion and a tongue plate 20e as a second end portion. The buckle body 20d is connected to an end of the first chest strap part 20a at the chest strap 20. The tongue plate 20e is joined to the end of the second chest band portion 20 b. The tongue plate 20e is inserted into the buckle main body 20d and connected, and the tongue plate 20e is pulled out from the buckle main body 20d and disconnected. The buckle 20c allows the first chest strap part 20a and the second chest strap part 20b to be connected and disconnected.

Fig. 3 (a) shows a cross section along the line IIIa-IIIa in fig. 2. Fig. 3 (b) shows a cross section along the line IIIb-IIIb.

Each first fixing body 24 is constituted by a belt. The first fixed body 24 is folded back, and the

end portions

24a and 24b are sewn to the shoulder strap 12. In this seatbelt 10, the

end portions

24a and 24b are sewn so as to overlap the first surface 12d on the inner side of the front shoulder belt portion 12 a. The first fixing body 24 is disposed along the longitudinal direction of the shoulder harness 12. In the first fixing body 24, a first overlapping portion 24c and a first insertion portion 24d are formed by the sewing. The first overlapping portion 24c is located below the first insertion portion 24d in the longitudinal direction of the shoulder harness 12.

Each of the second fixing bodies 26 is constituted by a band. The second fixed body 26 is folded back, and the

end portions

26a and 26b are sewn to the shoulder strap 12. In the seatbelt 10, the

end portions

26a and 26b are sewn so as to overlap the outer second surface 12e of the front shoulder belt portion 12 a. The second fixed body 26 is disposed along the longitudinal direction of the shoulder harness 12. The second surface 12e is a surface that is a back surface of the first surface 12 d. In the second fixed body 26, a second overlapping portion 26c and a second insertion portion 26d are formed by the sewing. The second overlapping portion 26c is located above the second insertion portion 26d in the longitudinal direction of the shoulder harness 12. The positional relationship between the second overlapping portion 26c and the second insertion portion 26d and the positional relationship between the first overlapping portion 24c and the first insertion portion 24d are vertically reversed in the longitudinal direction of the shoulder harness 12.

As shown in fig. 3 (a) and 3 (b), the first chest band portion 20a is folded back and the pair of end portions are overlapped and sewn. Thus, the first chest sewn portion 20f and the first chest insertion portion 20g are formed in the first chest band portion 20 a. The first chest insertion portion 20g is inserted through the first insertion portion 24d, the second insertion portion 26d, and the shoulder strap 12 (the front shoulder strap portion 12 a). Thus, the first chest strap part 20a is coupled to one shoulder strap 12.

Although not shown, the second chest band portion 20b is folded back and the pair of end portions are overlapped and sewn. Thus, the second chest band part 20b is formed with a second chest sewn part 20j and a second chest inserted part 20 k. The second chest insertion portion 20k is inserted through the other first insertion portion 24d, the other second insertion portion 26d, and the other shoulder strap 12 (the other front shoulder strap portion 12 a). In this way, the second chest piece 20b is coupled to the other shoulder strap 12, similarly to the first chest piece 20 a.

Fig. 4 shows a state in which the harness 10 is worn on the body model 28. The shoulder straps 12 are worn on the shoulders 28a of the body model 28. The leg band 14 is worn on the leg 28b of the body model 28. The chest strap 20 is positioned in front of the chest 28c of the body model 28. The tongue plate 20e is inserted into the buckle body 20d and connected thereto. The chest connecting ring 22 is connected to the chest band 20 and is located between the pair of shoulder straps 12.

Fig. 5 shows a state in which the phantom 28 of fig. 4 is suspended. Although not shown, the chest strap 20 is pulled upward by a lifeline connected to the chest connecting ring 22. Arrow Fa in fig. 5 represents a large impact load applied to the harness 10 in the event of a fall. The arrow Fc indicates the load acting on the chest strap 20. The arrow Fs indicates the load acting on the shoulder harness 12.

In the first chest strap part 20a, a tensile load from the first chest insertion part 20g toward the first chest sewn part 20f is generated by the load Fc. In the second chest band portion 20b, a tensile load from the second chest insertion portion 20k toward the second chest sewn portion 20j is generated by the load Fc. The chest band 20 is deformed into an inverted V-shape. The pair of shoulder straps 12 are bent inwardly toward each other along with the deformation of the chest strap 20.

Fig. 6 shows a coupling structure of a part of the shoulder strap 12, a part of the chest strap 20, the first anchor 24, and the second anchor 26. In the harness 10 of fig. 5, the chest strap 20 of fig. 6 is pulled upward by the load Fc. On the other hand, the shoulder belt 12 is pulled downward from the seam position of the first overlapping portion 24c by the load Fs. Thereby, a tensile load acts between the first chest insertion portion 20g of the chest band 20 and the first insertion portion 24d of the first fixing body 24.

At this time, a tensile load also acts between the first insertion portion 24d and the first overlapping portion 24 c. Since the shoulder harness 12 is inserted into the first chest insertion portion 20g, the tensile load acts in the longitudinal direction of the shoulder harness 12 between the first insertion portion 24d and the first overlapping portion 24 c. The tensile load does not act in a direction in which the first overlapping portion 24c is torn from the shoulder harness 12. The stitching of the first overlapping portion 24c and the shoulder strap 12 exerts high strength and excellent durability against this tensile load.

In the stitching of the first overlapping portion 24c with the shoulder harness 12, stitches are aligned perpendicular to the longitudinal direction of the shoulder harness 12. In this sewing, a tensile load is applied substantially uniformly to the sewing threads arranged perpendicularly to the longitudinal direction. The suture exhibits higher strength and more excellent durability.

In addition, a tensile load also acts between the first chest insertion portion 20g and the first chest sewn portion 20 f. In the first chest sewn portion 20f, the tensile load does not act in a direction of tearing the pair of overlapped end portions. A local load is suppressed from acting on the first chest sewn portion 20 f. The first chest sewn portion 20f exerts high strength and excellent durability against the tensile load. The first chest sewn portion 20f also exerts high strength and excellent durability against a large impact load at the time of falling.

The first fixing body 24 is constituted by a belt. The first fixing body 24 is folded back to form a first insertion portion 24d and a first overlapping portion 24 c. The first fixing body 24 can be easily configured by using the same band as the shoulder strap 12 and the chest strap 20. The first fixing body 24 of the present invention is not limited to a member formed of a band. For example, one end of a band-shaped band may be sewn to the shoulder strap 12 to form a first overlapping portion 24c, and the other end of the band may be coupled to a coupling metal to form a first insertion portion 24 d.

In the first fixed body 24, the first overlapping portion 24c is located below the first insertion portion 24d in the longitudinal direction of the shoulder harness 12. Thus, when a large impact load is applied in an upward direction such as the load Fc, the chest band 20 exerts high strength and excellent durability.

Here, although the connection structure of one shoulder strap 12, first chest strap portion 20a, and one first fixing body 24 has been described, the connection structure of the other shoulder strap 12, second chest strap portion 20b, and other first fixing body 24 also exhibits high strength and excellent durability.

Fig. 7 shows a state in which the chest strap 20 of the harness 10 is pulled downward by the load Fc'. The harness 10 includes a pair of second fixing bodies 26 in addition to the pair of first fixing bodies 24. At this time, the shoulder harness 12 is pulled upward by the load Fs' from the sewn position of the second overlapped portion 26 c.

When the chest strap 20 is pulled downward relative to the harness 10, a tensile load acts between the second insertion portion 26d and the second overlapping portion 26c of the second fixing body 26. Since the shoulder harness 12 is inserted into the first chest insertion portion 20g, the tensile load acts in the longitudinal direction of the shoulder harness 12 between the second insertion portion 26d and the second overlapping portion 26 c. The tensile load does not act in a direction of tearing the second overlapping portion 26c from the shoulder harness 12. The stitching of the second overlapped portion 26c and the shoulder strap 12 exerts high strength and excellent durability against the tensile load. When the wearer of the harness 10 is prevented from falling, the stitching of the second overlapping portion 26c and the shoulder strap 12 exerts high strength and excellent durability against a large impact load that pulls the chest strap 20 downward.

In the seatbelt 10, the second fixed body 26 is located on the second surface 12e, which is the back surface of the first surface 12d where the first fixed body 24 is located. The first fixing body 24 and the second fixing body 26 sandwich the shoulder harness 12 in the thickness direction of the shoulder harness 12. Thus, the chest band 20 is easily coupled to the shoulder straps 12, the first anchors 24, and the second anchors 26 via the one first chest insertion portion 20 g.

The first fixing body 24 and the second fixing body 26 may be located on either one of the first surface 12d and the second surface 12 e. For example, the first insertion portion 24d of the first fixing body 24 and the second insertion portion 26d of the second fixing body 26 may be provided at positions shifted in the longitudinal direction of the shoulder harness 12 and coupled to the chest insertion portions, respectively.

In the harness 10, the positional relationship between the second overlapping portion 26c and the second insertion portion 26d and the positional relationship between the first overlapping portion 24c and the first insertion portion 24d are opposite to each other in the longitudinal direction of the shoulder harness 12. In other words, the first fixing body 24 and the second fixing body 26 are arranged to be opposite in the vertical direction. Thus, the chest band 20 can exhibit high strength and excellent durability regardless of being pulled upward or downward. Further, the chest band 20 can exhibit high strength and excellent durability even when pulled upward or downward by a large impact load at the time of falling prevention.

In the seatbelt buckle 10, the first anchor 24 and the second anchor 26 are not limited to being arranged in opposite vertical directions. The first fixing body 24 and the second fixing body 26 may be arranged in the same direction in the longitudinal direction of the shoulder harness 12. This allows the shoulder straps 12 and the chest straps 20 to be more firmly connected. Since the harness 10 includes the second anchor 26, the connection structure between the shoulder harness 12 and the chest strap 20 can exhibit higher strength and more excellent durability.

The chest band 20 is connected to a chest connecting ring 22. The chest attachment ring 22 is attached to the lifeline. Thus, impact loads acting when a fall of the wearer is prevented act on the lifeline from the shoulder strap 12 via the chest strap 20. The harness 10 has excellent safety against falls. In the harness 10, the chest connecting ring 22 is directly connected to the chest strap 20, but the chest connecting ring 22 may be connected to the chest strap 20 via a harness or the like. In this case, it is preferable that a strap or the like is connected to the center of the chest band 20 in the longitudinal direction of the chest band 20 between the pair of shoulder straps 12.

In the harness 10, the chest strap 20 is described as an example, but the connecting strap is not limited to this. Any strap may be used as long as it is connected to the pair of shoulder straps 12 so as to cross each other. For example, the pair of shoulder straps 12 (rear shoulder strap portions 12b) may be coupled to the back of the wearer.

The chest band 20 is provided with a buckle 20 c. The buckle main body 20d and the tongue plate 20e can be connected and disconnected. The first chest band portion 20a and the second chest band portion 20b can be coupled and uncoupled. This allows the wearer to easily wear and use the harness 10 and to easily remove the harness. By providing the buckle 20c, it is possible to secure sufficient strength against an impact load at the time of falling prevention and to facilitate the attachment and detachment of the seatbelt 10.

Fig. 8 shows a harness 30 according to another embodiment of the present invention. Here, a description will be given of a structure different from the seatbelt 10, and a description of a structure identical to the seatbelt 10 will be omitted. The same components as those of the seatbelt buckle 10 will be described with the same reference numerals.

The harness 30 has the same structure as the harness 10 except that it does not include the second fixing body 26.

Fig. 9 shows a portion of the chest strap 20 and a pair of shoulder straps 12. Fig. 9 shows a state in which the shoulder belt 12 of the harness 30 is hooked on the shoulder of the wearer. Each first fixing body 24 has a first overlapping portion 24c and a first insertion portion 24 d. The first chest band portion 20a is formed with a first chest sewn portion 20f and a first chest insertion portion 20 g. The first insertion portion 24d and the shoulder strap 12 (the front shoulder strap portion 12a) pass through the first chest insertion portion 20 g. The second chest band portion 20b is formed with a second chest sewn portion 20j and a second chest insertion portion 20 k. The other first insertion portion 24d and the other shoulder strap 12 (the other front shoulder strap portion 12a) pass through the second chest insertion portion 20 k. Thus, the second chest strap part 20b is coupled to the other shoulder strap 12.

In this harness 30, when the wearer is prevented from falling, the stitching of the first overlapping portion 24c and the shoulder strap 12 exerts high strength and excellent durability against a large impact load that pulls the chest strap 20 upward.

As exemplified in the harness 30, the harness of the present invention is not limited to a harness including both the first anchor 24 and the second anchor 26. If the first fixing body 24 is provided like the harness 30, excellent safety can be exhibited against a large impact load that pulls the chest strap 20 upward. Although not shown, a harness type seatbelt having the second fixing body 26 without the first fixing body 24 can exhibit excellent safety against a large impact load pulling the chest strap 20 downward.

Examples

The effects of the present invention will be clarified by the following examples, but the present invention should not be construed as being limited thereto.

[ example 1]

A harness of the harness type shown in fig. 8 was prepared.

Comparative example 1
