Is a part for maintaining or eliminating. In the present embodiment, the tubular connector 122 is composed of a surface fastener extending in a strip shape. In this case, in the tubular connector 122, a pair of sticking portions configured by a sticking surface having a hook-shaped portion and a sticking surface having an annular portion on which the hook-shaped portion is hung makes the cloth-like mounting body 121 into a tubular shape. They are provided at both ends of each inner side surface of the cloth-shaped mounting body 121 when formed.
　第１信号線連結具１２３は、布状装着体１２１と接触検出信号線１２４とを互いに電気的かつ物理的に連結または分離するための部品であり、導電性を有する材料で構成されている。本実施形態においては、第１信号線連結具１２３は、凸部と凹部とが互いに着脱自在に嵌合し合うスナップボタンで構成されている。この第１信号線連結具１２３は、一対の凸側部品および凹側部品が布状装着体１２１および接触検出信号線１２４にそれぞれ設けられている。 The first signal line connector 123 is a component for electrically or physically connecting or separating the cloth-like mounting body 121 and the contact detection signal line 124 from each other, and is made of a conductive material. In the present embodiment, the first signal line connector 123 is composed of a snap button in which the convex portion and the concave portion are detachably fitted to each other. In this first signal line connector 123, a pair of convex-side components and concave-side components are provided on the cloth-like mounting body 121 and the contact detection signal line 124, respectively.
　接触検出信号線１２４は、布状装着体１２１と制御部１０３とを電気的に接続して布状装着体１２１から出力される接触検出信号を制御部１０３に伝達する電線である。この接触検出信号線１２４は、一方の端部が制御部１０３に接続されているとともに、他方の端部（先端部）に前記第１信号線連結具１２３が設けられている。また、接触検出信号線１２４には、第２信号線連結具１２５が設けられている。 The contact detection signal line 124 is an electric wire that electrically connects the cloth-shaped mounting body 121 and the control unit 103 and transmits the contact detection signal output from the cloth-shaped mounting body 121 to the control unit 103. The contact detection signal line 124 has one end connected to the controller 103, and the other end (tip) provided with the first signal line connector 123.

（ヘルメット装着検出装置１００の作動）
　次に、上記のように構成したヘルメット装着検出装置１００の作動について説明する。まず、使用者Ｕは、ヘルメット９０およびヘルメット装着検出装置１００をそれぞれ用意する。この場合、ヘルメット装着検出装置１００は、検出装置本体１０１内に電池が装着されており、前記ヘルメット装着検出プログラムの実行によるヘルメット９０の装着状態の検出処理を実行している。 (Operation of helmet wearing detection device 100)
Next, the operation of the helmet mounting detection device 100 configured as described above will be described. First, the user U prepares the helmet 90 and the helmet wearing detection device 100, respectively. In this case, in the helmet mounting detection device 100, the battery is mounted in the detection device main body 101, and the mounting state of the helmet 90 is detected by executing the helmet mounting detection program.
　次に、使用者Ｕは、ヘルメット装着検出装置１００をヘルメット９０に取り付ける。具体的には、使用者Ｕは、図４ないし図６にそれぞれ示すように、ヘッドバンド接触検出センサ１１０における布状装着体１１１をヘルメット９０のヘッドバンド９２に巻き付けて取り付けるとともに、顎紐接触検出センサ１２０を顎紐９４に巻き付けて取り付ける。この場合、使用者Ｕは、ヘッドバンド９２および顎紐９４における使用者Ｕの頭部に対向する内側面とは反対側の外側面に筒状連結具１１２，１２２が位置する向きで布状装着体１１１，１２１をそれぞれ巻き付けた筒状に形成して筒状連結具１１２，１２２を介して貼り合せる。これにより、布状装着体１１１，１２１は、ヘッドバンド９２および顎紐９４に対して周方向および長手方向（ヘッドバンド９２および顎紐９４の各形成方向）にそれぞれ変位可能な状態で取り付けられる。 Next, the user U attaches the helmet wearing detection device 100 to the helmet 90. Specifically, as shown in FIGS. 4 to 6, the user U winds and attaches the cloth-like mounting body 111 of the headband contact detection sensor 110 around the headband 92 of the helmet 90, and detects the contact of the chin strap. The sensor 120 is wound around the chin strap 94 and attached. In this case, the user U wears the cloth-like attachment in a direction in which the tubular connectors 112 and 122 are located on the outer surface of the headband 92 and the chin strap 94 that is opposite to the inner surface that faces the head of the user U. The bodies 111 and 121 are each formed into a wound tubular shape, and the bodies 111 and 121 are attached to each other via the tubular connectors 112 and 122. Accordingly, the cloth-shaped mounting members 111 and 121 are attached to the headband 92 and the chin strap 94 in a displaceable state in the circumferential direction and the longitudinal direction (the forming direction of the headband 92 and the chin strap 94), respectively.
　次に、使用者Ｕは、検出装置本体１０１をヘルメット９０に取り付ける。具体的には、使用者Ｕは、金属製または樹脂製の取付具９５を用意して検出装置本体１０１をヘルメット９０の帽体９１に取り付ける。この場合、使用者Ｕは、検出装置本体１０１を帽体９１における右側または左側のサイド部分に取り付けることができる。なお、使用者Ｕは、帽体９１におけるサイド部分以外の部分（例えば、ヘルメット９０のつば部または後頭部）に取り付けてもよいし、取付具９５を用いることなく両面テープまたは接着剤を用いて検出装置本体１０１を直接帽体９１に取り付けるようにしてもよい。 Next, the user U attaches the detection device body 101 to the helmet 90. Specifically, the user U prepares a metal or resin attachment 95 to attach the detection device body 101 to the hat body 91 of the helmet 90. In this case, the user U can attach the detection device main body 101 to the right or left side portion of the cap 91. It should be noted that the user U may attach the cap body 91 to a portion other than the side portion (for example, the brim portion or the back head portion of the helmet 90), or it may be detected using a double-sided tape or an adhesive without using the attachment 95. The apparatus main body 101 may be directly attached to the cap body 91.
　次に、使用者Ｕは、ヘルメット９０を装着する。具体的には、使用者Ｕは、帽体９１を頭部に被った後、顎紐９４を締める。この場合、使用者Ｕは、ヘッドバンド９２に装着されたヘッドバンド接触検出センサ１１０および顎紐９４に装着された顎紐接触検出センサ１２０が自身の額部分および顎部分に位置するようにヘッドバンド９２および顎紐９４に対してそれぞれ摺動させて位置調整する。 Next, the user U wears the helmet 90. Specifically, the user U puts the cap 91 on the head and then tightens the chin strap 94. In this case, the user U headbands so that the headband contact detection sensor 110 attached to the headband 92 and the chinstring contact detection sensor 120 attached to the chin strap 94 are located on their forehead and chin parts. The position is adjusted by sliding with respect to 92 and the chin strap 94, respectively.
　これにより、使用者Ｕは、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０を使用者Ｕの額部分および顎部分にそれぞれ接近させ接触させることができる。また、使用者Ｕは、第１信号線連結具１１３，１２３がスナップボタンで構成されているため、このスナップボタンの嵌合部分を回転させることによって接触検出信号線１１４，１２４の位置および向きをそれぞれ調整することもできる。 Thereby, the user U can bring the headband contact detection sensor 110 and the chin strap contact detection sensor 120 close to and contact the forehead part and chin part of the user U, respectively. In addition, since the first signal line connector 113, 123 is composed of a snap button, the user U rotates the fitting portion of the snap button to change the position and orientation of the contact detection signal line 114, 124. Each can be adjusted.
　これにより、ヘルメット装着検出装置１００の制御部１０３は、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０からそれぞれ出力される接触検出信号を用いてヘルメット９０の装着状態を判定するとともにその判定結果をホスト装置２００に送信する。このヘルメット９０の装着状態の判定処理は、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０に使用者Ｕの額部分および顎部分が接近または接触することによる静電容量の変化または抵抗値の変化を検出して行なわれるが、この判定処理については本発明に直接関わらないため、その説明は省略する。 Accordingly, the control unit 103 of the helmet wearing detection device 100 determines the wearing state of the helmet 90 using the contact detection signals output from the headband contact detecting sensor 110 and the chin strap contact detecting sensor 120, respectively, and the determination result. Is transmitted to the host device 200. The determination process of the wearing state of the helmet 90 is performed by changing the capacitance or the resistance value due to the forehead part and the chin part of the user U approaching or contacting the headband contact detection sensor 110 and the chin strap contact detection sensor 120. Although a change is detected and performed, this determination processing is not directly related to the present invention, and therefore its description is omitted.
　また、ホスト装置２００は、検出装置本体１０１から送信される検出結果信号を受信してヘルメット９０の装着状態を監視して記憶したり、管理者に報知したりする処理を実行する。このホスト装置２００の処理についても本発明に直接関わらないため、その説明は省略する。 Further, the host device 200 receives the detection result signal transmitted from the detection device main body 101, monitors and stores the wearing state of the helmet 90, and executes a process of notifying the manager. The processing of the host device 200 is also not directly related to the present invention, and therefore its explanation is omitted.
　このようなヘルメット９０の使用状態において、ヘルメット装着検出装置１００は、布状装着体１１１，１２１の筒状連結具１１２，１２２による各貼り合せ部分が外側に向かって突出しているため顎紐９４およびヘッドバンド９２に対して周方向に回転する位置ずれを抑制することができる。 In such a state of use of the helmet 90, the helmet attachment detection device 100 has the chin strap 94 and the chin strap 94 because the bonded portions of the cloth attachments 111, 121 by the tubular connectors 112, 122 are projected outward. It is possible to suppress the positional displacement of rotating in the circumferential direction with respect to the headband 92.
　また、使用者Ｕは、ヘルメット９０の使用状態において、検出装置本体１０１内に装着した電池が消耗した場合には、電池交換を行うことができる。具体的には、使用者Ｕは、第２信号線連結具１１５，１２５で接触検出信号線１１４，１２４を分離することで検出装置本体１０１をヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０からそれぞれ分離することができる。これにより、使用者Ｕは、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０をヘルメット９０に取り付けた状態で検出装置本体１０１を帽体９１から取り外して電池交換することができる。 Also, the user U can replace the battery when the battery mounted in the detection device body 101 is exhausted while the helmet 90 is in use. Specifically, the user U separates the contact detection signal lines 114 and 124 by the second signal line connectors 115 and 125 so that the detection device main body 101 is moved to the headband contact detection sensor 110 and the chinstring contact detection sensor 120. Can be separated from each. This allows the user U to remove the detection device body 101 from the cap body 91 and replace the battery while the headband contact detection sensor 110 and the chinstring contact detection sensor 120 are attached to the helmet 90.
　また、使用者Ｕは、ヘルメット９０の使用状態において、顎紐接触検出センサ１２０が汚損した場合には顎紐接触検出センサ１２０を交換することもできる。具体的には、使用者Ｕは、第１信号線連結具１２３によって布状装着体１２１を接触検出信号線１２４から分離して布状装着体１２１を顎紐９４から取り外すことができる。これにより、使用者Ｕは、新たな布状装着体１２１を顎紐９４に取り付けるとともに、第１信号線連結具１２３を介して接触検出信号線１２４に接続することができる。 Further, the user U can also replace the jaw string contact detection sensor 120 when the jaw string contact detection sensor 120 is soiled while the helmet 90 is in use. Specifically, the user U can separate the cloth-like mounting body 121 from the contact detection signal line 124 by the first signal line connector 123 and remove the cloth-like mounting body 121 from the chin strap 94. This allows the user U to attach the new cloth-like mounting body 121 to the chin strap 94 and connect it to the contact detection signal line 124 via the first signal line connector 123.
　次に、使用者Ｕは、ヘルメット９０の使用を終了する場合には、ヘルメット９０を脱ぐ。具体的には、使用者Ｕは、顎紐９４を弛めて帽体９１を自身の頭部から取り外す。この場合、使用者Ｕは、ヘルメット装着検出装置１００をヘルメット９０に取り付けた状態でヘルメット９０を保管することができる。 Next, when the user U finishes using the helmet 90, the user U takes off the helmet 90. Specifically, the user U loosens the chin strap 94 and removes the cap body 91 from his/her head. In this case, the user U can store the helmet 90 with the helmet wearing detection device 100 attached to the helmet 90.
　また、使用者Ｕは、ヘルメット９０を取り外した状態においては、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０を交換することができる。具体的には、使用者Ｕは、第１信号線連結具１１３，１２３によって布状装着体１１１，１２１を接触検出信号線１１４，１２４から分離して布状装着体１１１，１２１をヘッドバンド９２および顎紐９４からそれぞれ取り外すことができる。これにより、使用者Ｕは、新たな布状装着体１１１，１２１をヘッドバンド９２および顎紐９４にそれぞれ取り付けるとともに、第１信号線連結具１１３，１２３を介して接触検出信号線１１４，１２４に接続することができる。 Further, the user U can replace the headband contact detection sensor 110 and the chinstring contact detection sensor 120 when the helmet 90 is removed. Specifically, the user U separates the cloth-shaped mounting bodies 111 and 121 from the contact detection signal lines 114 and 124 by the first signal line connecting tools 113 and 123 to separate the cloth-shaped mounting bodies 111 and 121 from the headband 92. And can be removed from the chin strap 94, respectively. As a result, the user U attaches the new cloth-shaped attachments 111 and 121 to the headband 92 and the chin strap 94, respectively, and attaches them to the contact detection signal lines 114 and 124 via the first signal line connectors 113 and 123. Can be connected.
　また、使用者Ｕは、ヘルメット装着検出装置１００をヘルメット９０から取り外すこともできる。具体的には、使用者Ｕは、筒状に形成された布状装着体１１１，１２１を開いてヘッドバンド９２および顎紐９４から取り外すとともに、検出装置本体１０１を帽体９１から取り外す。これにより、使用者Ｕは、ヘルメット装着検出装置１００をヘルメット９０から取り外して保管することができる。 The user U can also remove the helmet wearing detection device 100 from the helmet 90. Specifically, the user U opens the tubular cloth-shaped mounting bodies 111 and 121 and removes them from the headband 92 and the chin strap 94, and also removes the detection device body 101 from the cap body 91. Accordingly, the user U can remove the helmet wearing detection device 100 from the helmet 90 and store it.
　上記作動説明からも理解できるように、上記実施形態によれば、ヘルメット装着検出装置１００は、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０がそれぞれ筒状に形成されてヘルメット９０におけるヘッドバンド９２および顎紐９４をそれぞれ包囲した状態で取り付けられるため、ヘッドバンド接触検出センサ１１０および顎紐接触検出センサ１２０を長期間に亘って安定的にヘッドバンド９２および顎紐９４にそれぞれ装着することができる。 As can be understood from the above description of the operation, according to the above-described embodiment, the helmet wearing detection device 100 has the headband contact detection sensor 110 and the chinstring contact detection sensor 120 each formed in a cylindrical shape and the headband in the helmet 90. The headband contact detection sensor 110 and the chinstring contact detection sensor 120 can be stably attached to the headband 92 and the chinstring 94, respectively, for a long period of time because the headband contact detection sensor 110 and the chinstring contact detection sensor 120 are attached so as to be surrounded. it can.
　さらに、本発明の実施にあたっては、上記実施形態に限定されるものではなく、本発明の目的を逸脱しない限りにおいて種々の変更が可能である。なお、各変形例の説明においては、上記実施形態と同様の部分については同じ符号を付して重複する説明は省略する。 Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. In the description of each modification, the same parts as those in the above-described embodiment are designated by the same reference numerals, and overlapping description will be omitted.
　例えば、上記実施形態においては、筒状連結具１１２，１２２は、面ファスナで構成することによって筒状に形成した布状装着体１１１，１２１の両端部を着脱自在に構成した。しかし、筒状連結具１１２，１２２は、筒状に形成した布状装着体１１１，１２１における互いに対向する部分を留めることができればよく、面ファスナ以外のボタン（ボタンホールを有するもの）、ホックまたはチャックで構成することができる。 For example, in the above-described embodiment, the tubular connectors 112 and 122 are configured such that both ends of the cloth-like mounting members 111 and 121 formed in a tubular shape by being configured with hook-and-loop fasteners are detachable. However, the tubular connectors 112 and 122 only need to be able to fasten portions of the tubular cloth-shaped mounting members 111 and 121 that face each other, and buttons (having buttonholes) other than hook-and-loop fasteners, hooks, or hooks. It can be composed of a chuck.
　また、筒状連結具１１２，１２２は、図７に示すように、ヘッドバンド９２および顎紐９４が貫通する筒状に形成した布状装着体１１１，１２１における互いに対向する部分を縫合によって連結するように構成してもよいし、各端部を接着によって連結するように構成することもできる。すなわち、筒状連結具１１２，１２２は、筒状に形成した布状装着体１１１，１２１における互いに対向する部分を固定的に接合することもできる。この場合、布状装着体１１１，１２１に対しても縫合または接着して固定的に設けることもできる。 In addition, as shown in FIG. 7, the tubular connectors 112 and 122 connect the mutually facing portions of the tubular cloth-shaped attachments 111 and 121 through which the headband 92 and the chin strap 94 pass, by stitching. Alternatively, the respective ends may be connected by adhesion. That is, the tubular connectors 112 and 122 can also be fixedly joined to the mutually opposing portions of the tubular cloth-shaped mounting members 111 and 121. In this case, the cloth-like mounting bodies 111 and 121 can also be fixedly provided by stitching or bonding.
　また、上記実施形態においては、筒状連結具１１２，１２２は、布状装着体１１１，１２１を筒状に形成した際における内側面にそれぞれ設けて布状装着体１１１，１２１の各両端部を貼り合せた際に外側に突出するように構成した。これにより、筒状連結具１１２，１２２は、布状装着体１１１，１２１がヘッドバンド９２および顎紐９４に装着された際の位置ずれを防止することができる。すなわち、筒状連結具１１２，１２２は、布状装着体１１１，１２１におけるそれぞれ同一面上に設けられている。 In addition, in the above-described embodiment, the tubular connectors 112 and 122 are provided on the inner side surfaces of the cloth-shaped mounting bodies 111 and 121 when they are formed into a tubular shape, and the two ends of the cloth-shaped mounting bodies 111 and 121 are connected to each other. It was configured so as to project to the outside when they are attached. As a result, the tubular connectors 112, 122 can prevent positional displacement when the cloth-shaped attachments 111, 121 are attached to the headband 92 and the chin strap 94. That is, the tubular connectors 112 and 122 are provided on the same surface of the cloth-shaped mounting members 111 and 121, respectively.
　しかし、筒状連結具１１２，１２２は、図８に示すように、布状装着体１１１，１２１における互いに反対面にそれぞれ設けることもできる。これによれば、筒状連結具１１２，１２２は、布状装着体１１１，１２１を筒状に形成した際に両端部における一方の端部（外側面）上に他方の端部（内側面）を重ねて貼り合せることができ外側への突出を抑えることができる。また、筒状連結具１１２，１２２は、チャックで構成した場合においては、筒状に形成した布状装着体１１１，１２１における各両端部にそれぞれ設けることができる。 However, as shown in FIG. 8, the tubular connectors 112 and 122 may be provided on the opposite surfaces of the cloth-shaped mounting members 111 and 121, respectively. According to this, the tubular connectors 112, 122 have one end (outer side surface) and the other end (inner side surface) on both ends when the cloth-shaped mounting bodies 111, 121 are formed in a tubular shape. Can be overlapped and bonded to each other, and the protrusion to the outside can be suppressed. Further, the tubular connectors 112 and 122 can be provided at both ends of the tubular cloth-shaped mounting members 111 and 121, respectively, when they are configured by chucks.
　また、上記実施形態においては、ヘッドバンド接触検出センサ１１０は、ヘッドバンド９２の外周部に密着して巻き付けられるように構成した。つまり、布状装着体１１１は、筒状連結具１１２が設けられていない部分の長さ、換言すれば、布状装着体１１１における２つの筒状連結具１１２間の長さがヘッドバンド９２の外周部の長さ（ヘッドバンド９２における布状装着体１１１の巻き付け方向の長さ）と略同じ長さに形成されている。これにより、ヘッドバンド接触検出センサ１１０は、ヘッドバンド９２が使用者Ｕの頭部に面する位置と同じ位置でヘッドバンド９２が使用者Ｕの頭部に面する面積と略同じ面積で布状装着体１１１が面することになる。しかし、ヘッドバンド接触検出センサ１１０は、ヘッドバンド９２などの被装着部の外周部に巻き付けられて取り付けられるように構成されていればよい。 Further, in the above-described embodiment, the headband contact detection sensor 110 is configured to be closely wound around the outer periphery of the headband 92. That is, in the cloth-shaped mounting body 111, the length of the portion where the tubular connector 112 is not provided, in other words, the length between the two tubular connectors 112 in the cloth-shaped mounting body 111 is the headband 92. It is formed to have substantially the same length as the length of the outer peripheral portion (the length in the winding direction of the cloth-shaped mounting body 111 in the headband 92). As a result, the headband contact detection sensor 110 has a cloth-like shape with an area substantially the same as the area where the headband 92 faces the head of the user U at the same position where the headband 92 faces the head of the user U. The mounted body 111 faces. However, the headband contact detection sensor 110 may be configured so as to be wound around and attached to the outer peripheral portion of the mounted portion such as the headband 92.
　したがって、ヘッドバンド接触検出センサ１１０は、例えば、図９に示すように、布状装着体１１１における２つの筒状連結具１１２間の長さをヘッドバンド９２の外周部の長さよりも十分に長く形成することができる。これにより、ヘッドバンド接触検出センサ１１０は、布状装着体１１１がヘッドバンド９２に取り付けられた際に、ヘッドバンド９２の長手方向に直交する方向（頭部の上下方向）に張り出して頭部に面し布状装着体１１１の頭部への接触面積が拡大するため、ヘルメット９０の装着状態を正確に検出することができる。 Therefore, in the headband contact detection sensor 110, for example, as shown in FIG. 9, the length between the two tubular connecting members 112 in the cloth-shaped mounting body 111 is sufficiently longer than the length of the outer peripheral portion of the headband 92. Can be formed. As a result, the headband contact detection sensor 110 protrudes in the direction orthogonal to the longitudinal direction of the headband 92 (vertical direction of the head) when the cloth-shaped mounting body 111 is attached to the headband 92, and the headband contact detection sensor 110 projects to the head. Since the contact area of the facing surface of the cloth-shaped mounting body 111 is increased, the mounting state of the helmet 90 can be accurately detected.
　なお、布状装着体１１１における２つの筒状連結具１１２間の長さは、特に限定されるものではないが、ヘッドバンド９２の外周部の長さの１．５倍以上かつ３倍以下の範囲が好ましい。また、布状装着体１１１の一部に導電性を有する部分が形成されている場合には、布状装着体１１１における２つの筒状連結具１１２間の長さとは、この長さ方向における導電性を有する部分の長さである。また、顎紐接触検出センサ１２０についてもヘッドバンド接触検出センサ１１０と同様に、布状装着体１２１における２つの筒状連結具１２２間の長さを顎紐９４の外周部の長さよりも十分に長く形成することができることは当然である。また、図９においては、ヘッドバンド９２に対して図示右側が使用者Ｕの頭部側となる。 The length between the two tubular connecting members 112 in the cloth-shaped mounting body 111 is not particularly limited, but is 1.5 times or more and 3 times or less than the length of the outer peripheral portion of the headband 92. A range is preferred. In addition, when a part having conductivity is formed in a part of the cloth-shaped mounting body 111, the length between the two tubular connecting members 112 in the cloth-shaped mounting body 111 means the conductivity in the length direction. It is the length of the part having sex. As for the chin strap contact detection sensor 120, similarly to the headband contact detection sensor 110, the length between the two tubular connecting members 122 in the cloth-shaped mounting body 121 is made sufficiently larger than the length of the outer peripheral portion of the chin strap 94. Of course, it can be formed long. In FIG. 9, the right side of the headband 92 is the head side of the user U.
　また、上記実施形態においては、第１信号線連結具１１３，１２３は、スナップボタンで構成した。しかし、第１信号線連結具１１３，１２３は、布状装着体１１１，１２１と接触検出信号線１１４，１２４とを電気的かつ物理的に連結または分離することができるように構成されていればよい。したがって、第１信号線連結具１１３，１２３は、スナップボタン以外の端子、例えば、ケーブルジョイントまたはコネクタなどの差込み型の端子で構成することができる。また、布状装着体１１１，１２１と接触検出信号線１１４，１２４とは、半田付けまたはステープラによって連結することもできる。 Also, in the above-described embodiment, the first signal line connector 113, 123 is configured by a snap button. However, if the first signal line connectors 113 and 123 are configured to electrically or physically connect or separate the cloth-like mounting bodies 111 and 121 and the contact detection signal lines 114 and 124, respectively. Good. Therefore, the first signal line connectors 113 and 123 can be configured with terminals other than snap buttons, for example, plug-in terminals such as cable joints or connectors. Further, the cloth-shaped mounting members 111 and 121 and the contact detection signal lines 114 and 124 can be connected by soldering or a stapler.
　また、上記実施形態においては、第１信号線連結具１１３，１２３は、布状装着体１１１，１２１における筒状連結具１１２，１２２が設けられた面の反対側の面、すなわち、布状装着体１１１，１２１を筒状に形成した場合における外側面に設けた。これにより、第１信号線連結具１１３，１２３は、布状装着体１１１，１２１を顎紐９４およびヘッドバンド９２に装着した状態で分離または連結し易くすることができる。しかし、第１信号線連結具１１３，１２３は、布状装着体１１１，１２１における筒状連結具１１２，１２２が設けられた面、すなわち、布状装着体１１１，１２１を筒状に形成した場合における内側面に設けることもできる。これによれば、第１信号線連結具１１３，１２３は、布状装着体１１１，１２１を筒状に形成した場合に筒内に配置されるためヘルメット９０の使用時における汚損を防止することができる。 Further, in the above-described embodiment, the first signal line connector 113, 123 is the surface opposite to the surface of the cloth-shaped mounting body 111, 121 on which the tubular connectors 112, 122 are provided, that is, the cloth-shaped mounting. The body 111, 121 is provided on the outer side surface when it is formed in a tubular shape. As a result, the first signal line connectors 113, 123 can be easily separated or connected with the cloth-shaped attachments 111, 121 attached to the chin strap 94 and the headband 92. However, when the first signal line connectors 113 and 123 are formed on the surface of the cloth-shaped mounting bodies 111 and 121 on which the tubular connectors 112 and 122 are provided, that is, when the cloth-shaped mounting bodies 111 and 121 are formed in a tubular shape. It can also be provided on the inner surface of. According to this, when the cloth-like mounting bodies 111 and 121 are formed in a tubular shape, the first signal line connectors 113 and 123 are arranged in the tube, so that the helmet 90 can be prevented from being damaged during use. it can.
　また、第１信号線連結具１１３，１２３は、布状装着体１１１，１２１と接触検出信号線１１４，１２４とを電気的かつ物理的に連結または分離することが不要な場合には省略することもできる。 The first signal line connectors 113 and 123 are omitted when it is not necessary to electrically or physically connect or separate the cloth-shaped mounting bodies 111 and 121 and the contact detection signal lines 114 and 124. Can also
　また、上記実施形態においては、第２信号線連結具１１５，１２５は、ケーブルジョイントで構成した。しかし、第２信号線連結具１１５，１２５は、接触検出信号線１１４，１２４の途中で接触検出信号線１１４，１２４自体を電気的かつ物理的に連結または分離することができるように構成されていればよい。したがって、第２信号線連結具１１５，１２５は、ケーブルジョイント以外のコネクタなどの差込み型の端子のほか、スナップボタン型の端子で構成することができる。 Also, in the above embodiment, the second signal line connector 115, 125 is composed of a cable joint. However, the second signal line connector 115, 125 is configured to electrically or physically connect or disconnect the contact detection signal line 114, 124 itself in the middle of the contact detection signal line 114, 124. Just do it. Therefore, the second signal line couplers 115 and 125 can be configured by snap-button terminals in addition to plug-in terminals such as connectors other than cable joints.
　なお、第２信号線連結具１１５，１２５は、第１信号線連結具１１３，１２３と同じ接続端子で構成することにより、第２信号線連結具１１５，１２５と第１信号線連結具１１３，１２３とを互いに連結することもできる。 The second signal line connector 115, 125 is configured with the same connection terminal as the first signal line connector 113, 123, so that the second signal line connector 115, 125 and the first signal line connector 113, 125 are connected. It is also possible to connect 123 and each other.
　また、上記実施形態においては、第２信号線連結具１１５，１２５は、接触検出信号線１１４，１２４の全長における制御部１０３側の長さを布状装着体１１１，１２１側の長さよりも長くなる位置に設けた。これにより、ヘルメット装着検出装置１００は、使用者Ｕがヘルメット９０を装着している場合において、接触検出信号線１１４，１２４を分離した際における布状装着体１１１，１２１から延びる接触検出信号線１１４，１２４の長さが短いため使用者Ｕの頭部から接触検出信号線１１４，１２４が垂れ下がる量が少なく不快感を軽減することができる。 In addition, in the above-described embodiment, the second signal line connector 115, 125 has the length of the control unit 103 side in the entire length of the contact detection signal line 114, 124 longer than the length of the cloth-shaped mounting body 111, 121 side. It was installed in the position. As a result, the helmet attachment detection device 100 allows the contact detection signal line 114 extending from the cloth- like attachments 111 and 121 when the contact detection signal lines 114 and 124 are separated when the user U is wearing the helmet 90.
