The shoulder anchor is fixed to the back of the seat in the vehicle interior and has a base portion having a contact portion with which the main surface of the belt can contact, and an opening that is formed integrally with the base portion so that the belt changes its direction. And an opening formed.
According to this seat belt device, since the base portion and the opening portion are integrally formed, the distance between the fixed portion where the base portion is fixed and the operating point of the opening portion where the force acts when the belt is pulled out. Since it is short, the moment acting on the shoulder anchor is small. As a result, it is possible to suppress an excessive moment from acting on the shoulder anchor when the belt is pulled out.
　また、前記基部は、前記車室を形成するバックパネルに固定されてもよい。 Further, the base may be fixed to a back panel that forms the vehicle interior.
　また、前記基部の前記接触部は、空隙を介して前記バックパネルに対向し、前記基部は、前記接触部の両側から前記バックパネルに向かって延出した延出部を更に有し、前記延出部は、前記バックパネルに固定されてもよい。 The contact portion of the base portion is opposed to the back panel through a gap, and the base portion further includes an extension portion extending from both sides of the contact portion toward the back panel, The protruding portion may be fixed to the back panel.
　また、前記基部は、前記ベルトに向かって突出した突出部を有し、前記ベルトは、引き出される際に前記突出部に対して摺動してもよい。 In addition, the base portion may have a protruding portion protruding toward the belt, and the belt may slide with respect to the protruding portion when pulled out.
　本開示の車両のシートベルト装置によれば、ベルトが引き出される際にショルダーアンカーに過大なモーメントが作用することを抑制できる。 According to the vehicle seat belt device of the present disclosure, it is possible to prevent an excessive moment from acting on the shoulder anchor when the belt is pulled out.

As shown in FIG. 4, the base 20 is configured such that the belt 12 can pass between the base 20 and the back panel 2a. As shown in FIG. 3, the base 20 has a flat plate portion 22 and a bent portion 24.
　平板部２２は、平板形状に形成されており、バックパネル２ａに空隙を介して対向している。平板部２２とバックパネル２ａとの間の距離は、ベルト１２が挿通できるような大きさに設定されている。平板部２２の裏面２２ａは、ベルト１２が引っ張られた際にベルト１２の主面が接触可能な接触部となっている。このため、ベルト１２は、平板部２２の裏面２２ａに対して面当てしやすくなり、ベルト１２が引っ張られる際にショルダーアンカー１６に作用する力を分散しやすくなる。 The flat plate portion 22 is formed in a flat plate shape and faces the back panel 2a via a gap. The distance between the flat plate portion 22 and the back panel 2a is set to such a size that the belt 12 can be inserted. The back surface 22a of the flat plate portion 22 is a contact portion that can contact the main surface of the belt 12 when the belt 12 is pulled. For this reason, the belt 12 is easily brought into contact with the back surface 22a of the flat plate portion 22, and the force acting on the shoulder anchor 16 is easily dispersed when the belt 12 is pulled.
　平板部２２には、図４に示すように、裏面２２ａからベルト１２へ突出する突出部であるビード２２ｂが形成されている。ビード２２ｂは、図３に示すように、ベルト１２の長手方向に沿うように車幅方向に所定間隔だけ離れて２つ形成されている。ベルト１２は、引っ張られる際に、ビード２２ｂに対して摺動する。これにより、ベース２０に対するベルト１２の摺動性が向上するので、ベルト１２がショルダーアンカー１６から円滑に引き出され、この結果、ベルト１２を引き出す際の容易性が向上する。 As shown in FIG. 4, the flat plate portion 22 is formed with a bead 22 b that is a protruding portion protruding from the back surface 22 a to the belt 12. As shown in FIG. 3, two beads 22 b are formed at a predetermined interval in the vehicle width direction along the longitudinal direction of the belt 12. The belt 12 slides with respect to the bead 22b when pulled. Thereby, since the slidability of the belt 12 with respect to the base 20 is improved, the belt 12 is smoothly pulled out from the shoulder anchor 16, and as a result, the ease of pulling out the belt 12 is improved.
　また、ビード２２ｂは、ベース２０を補強する機能を有する。これにより、ベルト１２が引き出される際にショルダーアンカー１６に過大な力（モーメント）が作用しても、ベース２０が変形等することを抑制できる。 Further, the bead 22b has a function of reinforcing the base 20. Thereby, even if an excessive force (moment) acts on the shoulder anchor 16 when the belt 12 is pulled out, the base 20 can be prevented from being deformed.
　曲げ部２４は、平板部２２の両端部からバックパネル２ａに向かって延出した延出部である。曲げ部２４は、ベルト１２の短手方向の両側を挟むように配置されており、ベルト１２をガイドする。また、曲げ部２４は、締結部材４０によってバックパネル２ａに固定されている（図２）。 The bent portion 24 is an extending portion that extends from both ends of the flat plate portion 22 toward the back panel 2a. The bent portion 24 is disposed so as to sandwich both sides of the belt 12 in the short direction, and guides the belt 12. Moreover, the bending part 24 is being fixed to the back panel 2a with the fastening member 40 (FIG. 2).
　開口部３０は、ベース２０の上方にベース２０と一体となるように構成されている。開口部３０には、図４に示すように、ベルト１２が通過する開口３１が形成されている。開口３１は、例えば、ベルト１２の断面形状より若干大きい矩形状に形成されている。ベルト１２は、開口３１を通過するために開口部３０の裏側で曲げられて、方向変換されることになる。 The opening 30 is configured to be integrated with the base 20 above the base 20. As shown in FIG. 4, an opening 31 through which the belt 12 passes is formed in the opening 30. For example, the opening 31 is formed in a rectangular shape that is slightly larger than the cross-sectional shape of the belt 12. The belt 12 is bent on the back side of the opening 30 in order to pass through the opening 31, and the direction of the belt 12 is changed.
　ベルト１２は、例えば引き出される際に開口部３０の開口３１の縁に接触し、当該縁には力が作用する。本実施形態では、力が作用する開口部３０の作用点とベース２０のバックパネル２ａへの固定点（締結部材４０によって固定されている部分）とが近くに位置するので、前記力に起因して発生するモーメントが大きくなることを抑制できる。 For example, when the belt 12 is pulled out, the belt 12 contacts the edge of the opening 31 of the opening 30, and a force acts on the edge. In the present embodiment, the action point of the opening 30 where the force acts and the fixing point (the portion fixed by the fastening member 40) of the base 20 to the back panel 2a are located close to each other. It is possible to suppress an increase in the moment generated.
　また、ベース２０が開口部３０と一体構成されているため、ウィンドウ開口２ｂ（図２）を有するバックパネル２ａであっても、乗員の肩部の近傍にショルダーアンカー１６を設けることが可能となる。 Further, since the base 20 is integrally formed with the opening 30, even if the back panel 2a has the window opening 2b (FIG. 2), the shoulder anchor 16 can be provided in the vicinity of the passenger's shoulder. .
　また、開口３１は、ベルト１２がバックル１８へ向かって斜めに掛け渡されるように、図３に示すように水平方向に対して斜めに形成されている。これにより、ベルト１２を引き出す際の容易性が向上することになる。 Further, the opening 31 is formed obliquely with respect to the horizontal direction as shown in FIG. 3 so that the belt 12 is stretched obliquely toward the buckle 18. Thereby, the ease at the time of pulling out the belt 12 is improved.
　＜本実施形態における効果＞
　上述した実施形態によれば、ショルダーアンカー１６は、キャビン２のリアシート３の背後（具体的には、バックパネル２ａ）に固定されたベース２０と、ベース２０と一体に構成された開口部３０とを有する。そして、ベース２０の裏面２２ａに対してベルト１２の主面が接触可能となっており、開口部３０には、ベルト１２が方向変換するように通過する開口３１が形成されている。
　このように、ベース２０と開口部３０が一体に構成されていることで、ベース２０のキャビン２に固定されている固定部分（締結部材４０によって固定されている部分）と、ベルト１２が引き出される際に力が作用する開口部３０の作用点との距離が短いため、ショルダーアンカー１６に作用するモーメントは小さい。この結果、ベルト１２が引き出される際に、ショルダーアンカー１６に過大なモーメントが作用することを抑制できる。 <Effect in this embodiment>
According to the embodiment described above, the shoulder anchor 16 includes the base 20 fixed to the back of the rear seat 3 of the cabin 2 (specifically, the back panel 2a), and the opening 30 formed integrally with the base 20. Have The main surface of the belt 12 can come into contact with the back surface 22a of the base 20, and the opening 30 is formed with an opening 31 through which the belt 12 changes its direction.
As described above, the base 20 and the opening 30 are integrally formed, whereby the fixing portion (the portion fixed by the fastening member 40) fixed to the cabin 2 of the base 20 and the belt 12 are pulled out. The moment acting on the shoulder anchor 16 is small because the distance from the acting point of the opening 30 where the force acts is short. As a result, it is possible to suppress an excessive moment from acting on the shoulder anchor 16 when the belt 12 is pulled out.
　なお、上記実施形態では、キャビン２は、２列のシート（フロントシート及びリアシート３）を有することとしたが、これに限定されない。例えば、キャビン２は、１列のシートを有してもよい。 In the above embodiment, the cabin 2 has two rows of seats (a front seat and a rear seat 3), but is not limited to this. For example, the cabin 2 may have one row of sheets.
　また、上記実施形態では、車両１がピックアップトラックであるとしたが、これに限定されない。例えば、車両１は、エンジンの上方にキャブが配置されるキャブオーバー型のトラックであってもよい。 In the above embodiment, the vehicle 1 is a pickup truck. However, the present invention is not limited to this. For example, the vehicle 1 may be a cab over type truck in which a cab is disposed above an engine.
　本開示の技術的範囲は上記実施形態に記載の範囲には限定されない。上記実施形態に、多様な変更又は改良を加えることが可能であることが当業者に明らかである。そのような変更又は改良を加えた形態も本開示の技術的範囲に含まれ得ることが、特許請求の範囲の記載から明らかである。 The technical scope of the present disclosure is not limited to the scope described in the above embodiment.
