The first insertion piece 7 is inserted to a position where it comes into contact with the stopper portion 11 of the insertion groove 9, so that the first insertion piece 7 is engaged with a predetermined position of the latch bracket 6 (the claw portion 15 and the projection portion 10 are engaged with each other). The insertion piece 7 is inserted into the position where the insertion piece 7 is prevented from coming off. In addition, since the insertion part 17 does not prevent the first insertion piece 7 from coming off, the first insertion piece 7 can be removed by pulling out the first insertion piece 7 in a state in which the engagement between the claw part 15 and the projection part 10 is released. One insertion piece 7 can be removed from the retaining bracket 6.

  The holding portion 18 is configured so that the second insertion piece 8 does not shift to the inside of the helmet body 2 in a state where the second insertion piece 8 is inserted into a predetermined position of the latch bracket 6. The piece 8 is held. Further, the second insertion piece 8 is positioned at a predetermined position of the latching bracket 6 at a position where the concave portion 19 provided on the upper end side of the holding portion 18 engages with the protrusion 23 of the second insertion piece 8. It will be.

  The second insertion piece 8 includes an attachment hole 20, an elastic locking claw member 21, a pair of claw portions 22, and a protruding portion 23. The attachment hole 20 is for attaching the chin strap 4 (see FIG. 1). The elastic locking claw member 21 is formed with a pair of claw portions 22 and a protruding portion 23.

  The claw portion 22 is formed integrally with the elastic locking claw member 21 so as to protrude from the outer surface of the elastic locking claw member 21, and has a shape that gradually protrudes outward from the lower side to the upper side. A locking claw surface 22a is provided at the upper end. The locking claw surface 22 a comes into contact with the locking claw surface 12 of the protrusion 10 in a state where the second insertion piece 8 is inserted to a predetermined position of the latching bracket 6. Due to the engagement between the locking claw surface 22a and the locking claw surface 12, the second insertion piece 8 can be prevented from coming off from the latch bracket 6. The claw portion 22 is automatically engaged (fitted) with the protruding portion 10 by the bending restoring force of the elastic locking claw member 21 when the second insertion piece 8 is inserted into a predetermined position of the latch bracket 6. The second insertion piece 8 is latched to the latch bracket 6 by this engagement. This latching does not come off unless the elastic locking claw member 21 is bent and the pair of claw portions 22 escapes to the inside of the pair of projections 10.

When the second insertion piece 8 is inserted to a predetermined position of the latching bracket 6, the elastic locking claw member 21 has its both ends (when viewed from the center, than the portion where the claw portion 22 is provided. The contact surfaces 21 a at both ends (outside) are positioned between the pair of knob portions 16 of the first insertion piece 7. With this configuration, in a state where the first insertion piece 7 and the second insertion piece 8 are disposed at predetermined positions of the latching bracket 6, the elastic locking claws can be operated by moving the pair of knob portions 16 closer to each other. Both ends of the member 21 can be brought close to each other. For this reason, by bringing the knob portion 16 close to each other, the elastic locking claw member 21 is bent in a direction in which the pair of claw portions 22 of the second insertion piece 8 approach each other, and the claw portion 22, the projection portion 10, Can be disengaged.
Therefore, since the user can use the knob portion 16 as a release button common to the first insertion piece 7 and the second insertion piece 8, the operability of the knob portion 16 becomes very good. That is, since the interior body hanging tool 5 employs a common engagement structure for the plurality of insertion pieces, when a plurality of interior bodies are attached to the plurality of insertion pieces, the user uses a common operation method. A plurality of different interior bodies can be attached and detached. Therefore, the user does not need to use a different operation method depending on the interior body in the operation of attaching / detaching the plurality of interior bodies to / from the helmet body, and therefore can easily and efficiently perform the work for attachment / detachment.

If each of the first insertion piece 7 and the second insertion piece 8 is provided with a release button having a size that can be easily pressed by a finger, there is a problem that the hanging bracket 6 becomes large. If each release button is made small in order to avoid this problem, there arises a problem that the easy detachability of the interior body hanging tool 5 (see FIG. 1) is impaired. Therefore, in order to solve these problems, the interior body hanging tool 5 is provided with the contact surface 21a of the second insertion piece 8 between the knob portions 16 of the first insertion piece 7 as described above. By adopting the configuration, the release buttons of a plurality of insertion pieces are stacked.
With this configuration, a plurality of insertion pieces can be removed from the latch bracket 6 by an operation on the knob portion 16. Moreover, since the knob part 16 is used as a release button common to a plurality of insertion pieces, the knob part 16 can be maintained in a size that does not impair the operability, thereby improving the operability. can do.

  The protrusion 23 engages with the stopper portion 19 of the first insertion piece 7, thereby positioning the second insertion piece 8 at a predetermined position of the latch bracket 6. Further, at the predetermined position, the recess 24 at the lower end of the second insertion piece 8 is also engaged with the connecting portion 25 that connects the elastic locking claw member 14 and the holding portion 18 of the first insertion piece 7. By these engagements, the second insertion piece 8 is fixed at a predetermined position in the vertical direction (the direction from the edge side to the back side of the helmet body 2). Further, the claw portion 22 of the second insertion piece 8 is sandwiched between the elastic locking claw member 14 and the holding portion 18 of the first insertion piece 7, so that the horizontal direction (perpendicular direction of the inner surface of the helmet body 2). ) Is fixed at a predetermined position.

  FIG. 4 is a main part side view for explaining the positional relationship between the first insertion piece 7 and the second insertion piece 8 at a predetermined position of the latch bracket 6. As shown in the figure, the elastic locking claw member 21 of the second insertion piece 8 located in the back of the insertion portion 17 of the first insertion piece 7 is the elastic locking of the first insertion piece 7. It is sandwiched between the claw member 14 and the holding portion 18. The contact surface 21 a of the elastic locking claw member 21 of the second insertion piece 8 is located inside the pair of knob portions 16 of the first insertion piece 7. Further, since the locking claw surface 15a of the claw portion 15 of the first insertion piece 7 and the locking claw surface 22a of the claw portion 22 of the second insertion piece 8 are located close to each other, the claw portion 15 and The nail | claw part 22 can be engaged with the projection part 10 (refer FIG. 3) of the latching bracket 6.

As shown in the figure, the first insertion piece 7 and the second insertion piece 8 are respectively positioned at predetermined positions of the latch bracket 6 by engaging the claw portion 15 and the claw portion 22 with the projection portion 10. Fixed.

FIG. 6 is a main part perspective view for explaining the relationship between the knob portion 16 of the first insertion piece 7 and the elastic locking claw member 21 of the second insertion piece 8. As shown in the figure, when both the contact surface 16a of the knob portion 16 and the contact surface 21a of the elastic locking claw member 21 are viewed from the inside of the helmet body 2 (see FIGS. 1 to 3), The helmet body 2 is formed in a shape that expands toward the inner peripheral edge 2 a side. That is, the contact surfaces 16a of the pair of knob portions 16 and the contact surfaces 21a of the pair of elastic locking claws 21 are both helmet bodies when viewed from the inside of the helmet body 2 (see FIGS. 1 to 3). 2 is widened toward the inner peripheral edge 2a side, that is, the distance between the pair of surfaces (the distance between the pair of contact surfaces 16a, the distance between the pair of contact surfaces 21a) of the helmet body 2. It is formed so as to be gradually widened toward the inner peripheral edge 2a side.
Therefore, when a force in a direction in which the pair of knob portions 16 approach each other (in the direction of arrow A in the figure) is applied to the knob portion 16 of the first insertion piece 7, the second insertion piece 8 is elastically locked. A force in a direction in which the claw portions 22 (see FIG. 3) approach each other is applied to the claw member 21, and a force in a direction in which the claw member 22 is pulled out from the latching bracket 6 (in the direction of arrow B in the drawing) is also applied. .
With this configuration, by operating the knob portion 16, the engagement between the claw portion 22 and the projection portion 10 can be released, and at the same time, the second insertion piece 8 can be pulled out from the latch bracket 6. Therefore, the user can remove the second insertion piece 8 from the latching bracket 6 with one touch by operating the knob portion 16, so that the chin strap 4 attached to the second insertion piece 8 can be removed. The property is good.

FIG. 7 is a front view of a main part for explaining the shape of the claw portion 15 of the first insertion piece 7. As shown in the figure, the first insertion piece 7 has a pair of claw portions 15 in a twisted shape, that is, in a state where the first insertion piece 7 is at a predetermined position of the latch bracket 6 (see FIG. 1 to 3), the claw portion 15 is formed so that the tip of the claw portion 15 is located closer to the inner peripheral edge 2a side of the helmet body 2 than the base end. When attention is paid to the locking claw surface 15a of the claw portion 15, when the first insertion piece 7 is in a predetermined position of the latch bracket 6, when viewed from the inside of the helmet body 2, the pair of claw portions 15 are locked. The claw surface 15a has a wider C shape on the inner peripheral edge 2a side. Further, the angle formed by the locking claw surface 15a and the elastic locking claw member 14 indicated by A in FIG. 7 is an acute angle. Thus, when the first insertion piece 7 is inserted into a predetermined position of the latch bracket 6 and a force in the direction of pulling out from the latch bracket 6 is applied to the first insert piece 7, the elastic latch The claw member 14 bends in the direction in which the gap between the pair of claw portions 15 opens (the direction opposite to the direction in which the engagement is disengaged). That is, when a force in the direction of pulling out from the latching bracket 6 is applied to the first insertion piece 7, the protruding portion 10 bites between the claw portion 15 and the elastic locking claw member 14. 10 and the claw part 15 can be more firmly engaged.
