[0003] For example, Patent Document 1 discloses a technique in which a reflector for reflecting radar waves is provided on a saddle-riding type vehicle (motorcycle).

[0004] Prior art literature

[0005] Patent Document 1: Japanese Patent Application Publication No. 2022-52291 Summary of the invention

[0006] Problems to be solved by the invention

[0007] In Patent Document 1, the reflector for reflecting radar waves is provided on the saddle-riding type vehicle, so the reflector cannot be arranged at a position higher than the torso of the driver who drives the saddle-riding type vehicle. Therefore, it is difficult to effectively reflect radar waves emitted from a distance.

[0008] In view of the above background, the present invention aims to effectively reflect radar waves emitted from a distant place and to contribute to the development of a sustainable transportation system.

[0009] Means for solving problems

[0010] In order to solve the above-mentioned problems, one embodiment of the present invention is a helmet 1, which has: a cap body 4, which covers the head of a wearer W; a front reflector 69, which is arranged on the front side of the cap body and reflects radar waves; and a rear reflector 34, which is arranged on the rear side of the cap body and reflects radar waves.

[0011] According to this method, by providing the front reflector and the rear reflector on the helmet, the front reflector and the rear reflector can be arranged at a position higher than the torso of the wearer. Therefore, radar waves emitted from a distance can be effectively reflected. Furthermore, it is conducive to the development of a sustainable transportation system.

[0012] In the above aspect, an attachment 5 detachably mounted on the cap body may be provided, and the front reflector and the rear reflector may be provided on the attachment.

[0013] According to this aspect, the front reflector and the rear reflector can be provided on the helmet without performing special processing on the cap body.

[0014] In the above embodiment, the accessory may also include: a chin protection portion 48 that protects the chin of the wearer; and a back of the head protection portion 14 that protects the back of the wearer's head, the front reflectors are respectively arranged on the left and right side portions of the chin protection portion, and the rear reflectors are arranged on the left and right central portions of the back of the head protection portion.

[0015] According to this aspect, the chin guard for protecting the chin of the wearer can be used as the installation space for the front reflector, and the back of the head guard for protecting the back of the wearer's head can be used as the installation space for the back reflector.

[0016] In the above aspect, the front reflector provided on the left side of the chin guard may open toward the left front, the front reflector provided on the right side of the chin guard may open toward the right front, and the rear reflector may open toward the rear.

[0017] According to this aspect, radar waves emitted from the left front, right front, and rear of the wearer can be reflected over a wide range.

[0018] In the above aspect, each of the front reflectors may be recessed on the surface of the chin guard, and a raised portion 70 may be provided on the surface of the chin guard to surround each of the front reflectors.

[0019] According to this aspect, the depth of each front reflector can be increased by the amount corresponding to the provision of the raised portion, thereby increasing the surface area of ​​each front reflector and improving the reflection performance of each front reflector.

[0020] In the above aspect, the rear head protection portion may include left and right light emitting portions 28E and 28F that emit light toward the outside of the helmet, and the rear reflector may be provided between the left and right light emitting portions.

[0021] According to this mode, the design integrity of the left and right luminous parts and the rear side reflector can be improved, so the appearance of the helmet can be improved. In addition, the left and right luminous parts are isolated by the rear side reflector, so it is easy to distinguish the left and right luminous parts.

[0022] In the above-mentioned embodiment, the rear head protection portion may also include: a shell 22 formed of a translucent material to accommodate the left and right light-emitting portions; and a cover 23 formed of a non-translucent material to be mounted on the outer surface of the shell, and the rear reflector is arranged on the cover.

[0023] According to this aspect, the rear reflector can be formed with a simple structure.

[0024] In the above aspect, the front reflector and the rear reflector may be formed by covering a recessed portion provided on a surface of a resin material with a metal thin film.

[0025] According to this aspect, if the front side reflector or the rear side reflector accidentally comes into contact with an object around the wearer, it is possible to suppress the front side reflector or the rear side reflector from damaging the object around the wearer.

[0026] In the above aspect, the front reflector and the rear reflector may be formed of triangular pyramid-shaped corner reflectors.

[0027] According to this aspect, the shapes of the front side reflector and the rear side reflector can be simplified, and thus the front side reflector and the rear side reflector can be easily formed.

[0028] In order to solve the above-mentioned problems, one embodiment of the present invention is an accessory 5, which is installed on the cap body 4 covering the head of the wearer W in a detachable manner, and together with the cap body constitutes a helmet 1, and the accessory has: a front reflector 69, which is arranged on the front side of the cap body to reflect radar waves; and a rear reflector 34, which is arranged on the rear side of the cap body to reflect radar waves.

[0029] According to this method, by providing the front side reflector and the rear side reflector as accessories of the helmet, the front side reflector and the rear side reflector can be arranged at a position higher than the torso of the wearer. Therefore, radar waves emitted from a distance can be effectively reflected. In addition, the front side reflector and the rear side reflector can be provided on the helmet without performing special processing on the cap body. Furthermore, it is conducive to the development of a sustainable transportation system.
