When the gap is reduced, it is removed from the mounting hole H. That is, the distal end of the mounting portion 20 includes a fastening portion 24 having a structure that stays in the attached portion F, and a through hole 22H having a U-shape around the fastening portion 24. The mounting flexible portion 23 and the mounting annular portion 22 each having a cantilever shape are defined at the distal end of the mounting portion 20.

  The mounting flexible portion 23 located at the tip of the mounting portion 20 uses a through hole 22H that is a gap between the mounting flexible portion 23 and the mounting annular portion 22, and is located at a position relative to the mounting portion 20 relative to the mounting portion 20. At the same time, they bend or twist.

  With such a structure for mounting a helmet interior, the relative position of the helmet headband with respect to the mounting target can be changed in a wide range. As a result, it is possible to improve the consistency between the shape of the wearer's head and the ring shape of the helmet headband.

  In the following description, as one embodiment of a mounting structure for a helmet interior, each mounting portion 20 includes a mounting main body portion 21 and a mounting annular portion 22 located at a tip of the mounting portion 20. The case where the connecting portion 22A, which is a part of the annular portion 22, is formed integrally with the mounting body 21 is shown, but the connecting portion 22A may be provided as a separate member. In short, it is sufficient that the helmet interior has a mounting structure that maintains the relationship between the mounting portion 20 and the mounted portion F.

  Further, as one embodiment, the mounting main body 21 connects the band main body 10 and the mounting annular portion 22, and has a band width larger than the line width of the ring of the mounting annular portion 22. It has higher rigidity than 22. In addition, the attachment main body 21 has a higher band width than the attachment flexible portion 23, and thus has higher rigidity than the attachment flexible portion 23. The attachment main body 21 may have a higher rigidity than the attachment annular portion 22 by having a thickness greater than the thickness of the attachment annular portion 22. Further, the attachment main body 21 may have a higher rigidity than the attachment flexible portion 23 by having a thickness greater than the thickness of the attachment flexible portion 23. That is, as one embodiment, the mounting portion 20 is fixed to a mounting main body portion 21 having a cantilever shape having a fixed end on the band main body portion 10 and a mounting annular portion 22 located at a free end of the mounting main body portion 21. A mounting flexible portion 23 having a cantilever shape with an end, and the flexibility of the mounting flexible portion 23 is higher than the flexibility of the mounting body 21.

  Each of the band ends 13 and 14 constitutes an end of the band main body 10 and can be connected to each other by engaging the adjusting teeth 13B and the band fasteners 14B. One band connecting portion 12 has a ladder shape connecting one band end portion 13 and one end of the band central portion 11. The other band connecting portion 12 also has a ladder shape for connecting the other band end portion 14 and the other end at the band center portion.

  The band central portion 11 has a ladder shape extending in the extending direction A1 of the band central portion 11. The band central portion 11 includes a pair of upper and lower central frames 15A and 15B, and a plurality of central bridge frames 16 that bridge the pair of central frames 15A and 15B. Two attachment portions 20 as an example of the suspension portion extend upward from the upper central frame 15B with the central axis C of the band central portion 11 interposed therebetween.

  The lower central frame 15A has a fine line shape that draws a gentle arc that is convex downward. The upper central frame 15B has a similar shape to the lower central frame 15A at a central portion thereof in the extending direction A1, and has a smaller radius of curvature than the lower central frame 15A at both ends thereof in the extending direction A1. And has a wavy line drawing an arc having. Each central bridge frame 16 has a thin line shape thinner than the pair of central frames 15A, 15B, and has a function of maintaining the distance between the pair of central frames 15A, 15B.

  The portion to which the central bridge frame 16 is connected in the lower central frame 15A is closer to the central axis C of the band central portion 11 than the portion to which the central bridge frame 16 is connected in the upper central frame 15B. In other words, the left and right central bridge frames 16 sandwiching the central axis C of the band central portion 11 are located on a V-shape having a bent portion on the central axis C of the band central portion 11.

  According to such an arrangement of each central bridge frame 16, the upper central frame 15 </ b> B is extended more than the lower central frame 15 </ b> A as compared with a configuration in which each central bridge frame 16 simply extends along the central axis C. The central bridge frame 16 is easy to tolerate due to its deformation.

  Each band connecting portion 12 has a ladder shape crossing the extending direction A1 of the band central portion 11. Each band connecting portion 12 includes a pair of upper and lower connecting frames 17A and 17B, and three bridge frames 18 that bridge the pair of connecting frames 17A and 17B.

  The lower connecting frame 17A located on the left side of FIG. 1 is integral with the left end of the lower central frame 15A, and has a thin line shape that draws an arc that projects upward and to the left. The upper connecting frame 17B located on the left side of FIG. 1 is integral with the left end of the upper central frame 15B, and is also an arc that is convex toward the upper left, and has a larger radius of curvature than the lower connecting frame 17A. It has a thin line shape that draws an arc with. One attachment portion 20, which is an example of the suspension portion, extends toward the upper left from the upper connection frame 17B.

  The lower connecting frame 17A located on the right side of FIG. 1 is integral with the right end of the lower central frame 15A and has a thin line shape that draws an arc that projects upward and to the right. The upper connecting frame 17B located on the right side of FIG. 1 is integral with the right end of the upper central frame 15B, which is also an arc that is convex toward the upper right, and has a larger radius of curvature than the lower connecting frame 17A. It has a thin line shape that draws an arc with. One attachment portion 20, which is an example of the suspension portion, extends from the upper connection frame 17B toward the upper right.

  In each band connecting portion 12, each cross-linking frame 18 has a thin line shape thinner than the pair of connecting frames 17A, 17B, and has a function of maintaining the distance between the pair of connecting frames 17A, 17B. The helmet headband has a shape that is substantially line-symmetric with respect to the center axis C, and each bridge frame 18 also has a shape that is substantially line-symmetric with respect to the center axis C, and has a band center portion. 11 has a linear shape extending along the extending direction A1.

  As shown in FIG. 2, in plan view of the helmet headband, the band central portion 11 and the pair of left and right band connecting portions 12 have a linear shape extending along the extending direction A1 of the band central portion 11. On the other hand, the pair of left and right band ends 13 and 14 has a gentle curved shape that is concave in an inner direction A2 perpendicular to the extending direction A1 of the band center portion 11.

  The band main body 10 is in a state in which the adjusting teeth 13B of one band end 13 and the band fastener 14B of the other band end 14 are engaged with each other, and the pair of band ends 13, 14 are connected to each other. Has a ring shape. The band-like portion 13A of the one band end 13 has flexibility and elasticity having a curved surface following the ring shape formed by the band main body 10 in a state where external stress is removed. The other band end portion 14 also has flexibility and elasticity having a curved surface shape following the ring shape formed by the band main body portion 10 when the external stress is removed.

  As shown in FIG. 3, one band end 13 includes a band 13A having a surface extending along the extending direction of the band end 13 and a plurality of adjustment teeth 13B arranged on the surface of the band 13A. Prepare. Each adjusting tooth 13B has a triangular shape that becomes narrower in the direction opposite to the inner direction A2 from the surface of the band-shaped portion 13A when viewed from the width direction AW of the band end portion 13. Further, each adjusting tooth 13B has such a shape that the width in the width direction AW becomes smaller toward the front end when viewed from the extending direction of the band end portion 13.

  The band end portion 13 includes a reinforcing portion 13T having a curved shape following the ring shape formed by the band main body portion 10. The reinforcing portion 13T connects the adjusting teeth 13B adjacent to each other substantially to the center in the width direction AW of each adjusting tooth 13B, and is substantially the same as the height T of the adjusting tooth 13B from the surface of the band portion 13A. Have a height. In other words, the adjusting teeth 13B constituting the band end 13 are connected by the reinforcing portion 13T having substantially the same height as that of the adjusting tooth 13B and having a curved shape following the ring shape.

  With such a structure of the band end portion 13, even if the band-shaped portion 13A has a small thickness, the entire shape of the band end portion 13 can easily follow the above-mentioned ring shape, and each adjusting tooth can be adjusted. It is also possible to suppress that 13B falls down with respect to the strip 13A. And while the band main body part 10 has flexibility as a whole, the band end part 13 has the shape retention of the reinforcement part 13T compared with the band center part 11 and the band connection part 12 among them. Enhanced by rigidity.

  As shown in FIG. 4, the mounted portion F is provided, for example, on a hammock, which is an example of a mounting target to which the mounting portion 20 is mounted, and the front end of the mounted portion F has a mounting hole H. In addition, the to-be-attached part F may be provided, for example, with an interior material other than the hammock attached to the cap body 30, or may be provided with the cap body 30 itself, which is an example of an attachment target, and fastens the mounting part 20. What is necessary is just to have a structure. The hammock is a resin member having flexibility, for example, low density polyethylene (LDPE), linear low density polyethylene (L-LDPE), high density polyethylene (HDPE), polypropylene (PP), polyacetal ( POM) and polyamide (PA). The cap body 30 is formed of, for example, acrylonitrile butadiene styrene (ABS), polycarbonate (PC), glass fiber reinforced plastic (FRP), or carbon fiber reinforced plastic (CFRP).

  Each mounting portion 20 includes a mounting annular portion 22 located at the tip of the mounting portion 20, a mounting flexible portion 23, and a fastening portion 24. The mounting flexible portion 23 has a fixed end 23A that is integral with the mounting annular portion 22, and has a cantilever shape having a free end in the ring of the mounting annular portion 22. The fastening portion 24 has a structure that is located at a free end of the mounting flexible portion 23 and stays at the mounted portion F.

  For example, if the tip of the mounting portion F has a mounting hole H, the fastening portion 24 is configured as a pair of key claws that fit into the mounting hole H of the mounting portion F. When the gap is reduced, it is removed from the mounting hole H. That is, the distal end of the mounting portion 20 includes a fastening portion 24 having a structure that stays in the attached portion F, and a through hole 22H having a U-shape around the fastening portion 24. The mounting flexible portion 23 and the mounting annular portion 22 each having a cantilever shape are defined at the distal end of the mounting portion 20.

  The mounting flexible portion 23 located at the tip of the mounting portion 20 uses a through hole 22H that is a gap between the mounting flexible portion 23 and the mounting annular portion 22, and is located at a position relative to the mounting portion 20 relative to the mounting portion 20. At the same time, they bend or twist. For example, the mounting flexible portion 23 bends along a bending direction D2 about an axis along the extending direction A1, and mounts flexible along a twisting direction D1 about an axis along the width direction AW. The part 23 is twisted. Therefore, it is possible to change the position of the helmet headband relative to the mounting object in a wide range. As a result, it is possible to improve the consistency between the shape of the wearer's head and the ring shape of the helmet headband.

  The fixed end 23A of the mounting flexible portion 23 is farther from the connecting portion 22A than the free end of the mounting flexible portion 23. More specifically, the fixed end 23A of the mounting flexible portion 23 is located on the upper side of the inner edge of the mounting annular portion 22, and the free end of the mounting flexible portion 23 is located on the lower side of the inner edge of the mounting annular portion 22. And the lower end of the mounting annular portion 22 is a connecting portion 22A. That is, in each mounting portion 20, the fixed end 23A of the mounting flexible portion 23 and the connecting portion 22A face each other with the free end of the mounting flexible portion 23 interposed therebetween.

  The mounting annular portion 22, which is integral with the fixed end 23A of the mounting flexible portion 23, receives the accompanying stress from the mounting flexible portion 23 when the mounting flexible portion 23 is bent or twisted, and can be mounted. The stress received from the bending portion 23 is transmitted to the mounting body 21. On the other hand, as described above, the attachment main body 21 has higher rigidity than the attachment annular portion 22 by having a band width larger than the line width of the ring of the attachment annular portion 22. Such a structure included in the mounting body 21 enhances the mechanical strength of the mounting portion 20, particularly, the mechanical strength of the mounting annular portion 22.

  Here, in the above-described configuration, the fixed end 23A of the mounting flexible portion 23 is integrated with the mounting annular portion 22, and the fixed end 23A of the mounting flexible portion 23 is connected more than the free end of the mounting flexible portion 23. It is remote from the portion 22A. Therefore, as compared with the configuration in which the fixed end 23A and the connecting portion 22A are integrated, the mounting annular portion 22 is more likely to be deformed according to the stress transmitted from the mounting flexible portion 23 to the mounting annular portion 22.

  For example, when the mounting flexible portion 23 bends along the bending direction D2, the mounting annular portion 22 also easily bends along the bending direction D2 according to the stress along the bending direction D2. Further, when the mounting flexible portion 23 is twisted along the torsional direction D1, the mounting annular portion 22 is also easily twisted along the torsional direction D1 according to the stress along the torsional direction D1. Therefore, it is possible to widen the range in which the free end of the mounting flexible portion 23 is displaced by the displacement of the mounting annular portion 22, and to match the shape of the wearer's head with the ring shape of the helmet headband. Can be further increased.

  As shown in FIG. 5, the helmet includes a cap body 30 having a hollow hemisphere and a helmet headband. On the inside of the cap body 30, the above-described mounted portion F is located along the circumferential direction of the cap body 30. Each mounting portion 20 included in the helmet head band is mounted on a mounted portion F located inside the cap body 30 and has a ring shape by connecting a pair of band ends 13 and 14 to each other.

  Here, each band connecting portion 12 having a ladder shape extends so as to protrude downward from the surface SH including the band central portion 11. On the other hand, the bridge frame 18 included in each band connecting portion 12 extends in a direction substantially parallel to the plane SH including the band central portion 11, specifically, in a circumferential direction of the cap body 30. And in each band connecting part 12, each bridge | crosslinking frame 18 is a structure substantially parallel to the surface containing the band center part 11. As shown in FIG. Therefore, for the pair of connecting frames 17A and 17B included in each band connecting portion 12, the bridge frame 18 can function as a broken line common to the band connecting portions 12.

  For example, when the band body 10 is tightened to the wearer's head, the position of the band end 14 with respect to the band end 13 is adjusted. At this time, since the height of the hammock and the height of the cap body 30 are almost fixed by the top of the wearer, the height of each mounting portion 20 is also substantially fixed. Then, the entire band body 10 is displaced toward the center of the ring shape formed by the band body 10. As a result, each mounting portion 20 that connects the mounting object such as a hammock or a cap to the band main body 10 has a base end of the mounting portion 20 that is larger than a distal end of the mounting portion 20 due to the displacement of the band main body 10. It is displaced so as to be located radially inside.

  At this time, since the mounting portions 20 dispersed in the circumferential direction of the cap body 30 have a common shape, the displacement of each mounting portion 20 is also substantially the same, and the ring shape formed by the band main body portion 10 is deformed into distortion. Is suppressed. Further, since the displacement of the free end of each mounting flexible portion 23 is expanded with the deformation of each mounting annular portion 22, it is easy to adapt to the reduction in the diameter of the band main body 10.

The shape of the back of the head of the wearer is closer to the neck of the wearer in the radial direction of the above-described ring shape. For this reason, it is preferable that the band ends 13 and 14, which are portions facing the back of the head of the wearer, be more easily displaced to the inside of the ring shape than other portions of the band main body 10. In this regard, according to the configuration of the helmet headband described above, each of the band connecting portions 12 is easily bent along the bending direction D3 having the bridge frame 18 as a bending line, whereby the band ends 13 and 14 are described above. It is easy to be displaced inward in the radial direction of the ring shape. Therefore, it is possible to enhance the consistency between the shape of the wearer's head and the shape of the helmet headband, and in particular, to enhance the consistency between the position of the wearer's occiput and the positions of the band ends 13 and 14. It is also possible.
As described above, according to the above-described embodiment, the following effects can be obtained.

  (1) In a state where the mounting portion 20 is mounted on the mounting portion F, the mounting flexible portion 23 located at the tip of the mounting portion 20 is adjusted to the relative position of the mounting portion F with respect to the mounting portion 20. It bends and twists. Therefore, it is possible to improve the consistency between the shape of the wearer's head and the ring shape of the helmet headband.

  (2) Since the mounting annular portion 22 is also easily deformed according to the stress transmitted from the mounting flexible portion 23 to the mounting annular portion 22, the consistency between the shape of the wearer's head and the ring shape of the helmet headband is further improved. It is also possible to increase.

  (3) Since each of the band connecting portions 12 is easily bent in the same direction with the cross-linking frame 18 as a folding line, it is possible to particularly improve the alignment of the positions of the back of the wearer and the band ends 13 and 14.

  (4) Since each of the band ends 13 and 14 has a curved shape following the ring shape formed by the band main body 10, it is easy to match the shape of the entire band end to the shape of the wearer's head. But also.

(5) Since the degree of displacement at the free end of each mounting flexible portion 23 is substantially equal to each other, it is easy to adapt to the reduced diameter of the ring shape formed by the band main body 10.
The above embodiment can be modified and implemented as follows.
[Mounting flexible part]

  All of the mounting portions 20 included in the helmet headband may include the mounting portion 20 having the mounting flexible portion 23 and the mounting portion 20 having no mounting flexible portion 23. As a configuration of the mounting portion 20 having no mounting flexible portion 23, for example, a configuration in which the free end of the mounting flexible portion 23 and the connecting portion 22A are integrated is mentioned. If the free end of the mounting flexible portion 23 and the connecting portion 22A are integrated, the mechanical resistance of the mounting portion 20 itself can be increased. If the helmet headband includes the portion 20 and the attachment portion 20 having no attachment flexible portion 23, the mechanical resistance of the helmet headband can be enhanced.

  -All the attachment parts 20 included in the helmet headband may include attachment parts 20 in which the positions of the fixed ends 23A of the attachment flexible parts 23 are different from each other. For example, the fixed end 23A of the mounting flexible portion 23 and the connecting portion 22A face each other across the free end of the mounting flexible portion 23, and the free end of the mounting flexible portion 23 and the connecting portion 22A. May include a mounting portion 20 facing each other across the fixed end of the mounting flexible portion 23.

  The fixed end 23A of the mounting flexible portion 23 may be integral with the inner edge of the mounting annular portion 22. For example, the free end of the mounting flexible portion 23 and the connecting portion 22A may be connected to the fixed end of the mounting flexible portion 23.
