Description

アンカ板及びアンカ板の回り止め構造Anchor plate and anchor plate detent structure
 本開示は、アンカ板及びアンカ板の回り止め構造に関する。 This disclosure relates to an anchor plate and an anchor plate rotation prevention structure.
 一般的に、車両のシートベルト用バックルは、車体の一部(例えば、補強用パネル)にボルト締めされたアンカ板を介して固定される。このアンカ板は、バックルに引張力が働くと、上記ボルトを回転軸として回転することがある。このため、アンカ板に隣接した車体の位置にビード(即ち、突起部)を設けて、アンカ板の回り止めを行うものがある(例えば、特許文献1参照)。 Generally, a vehicle seat belt buckle is fixed via an anchor plate bolted to a part of a vehicle body (for example, a reinforcing panel). The anchor plate may rotate around the bolt as a rotation axis when a tensile force acts on the buckle. For this reason, a bead (that is, a protrusion) is provided at a position of the vehicle body adjacent to the anchor plate to prevent the anchor plate from rotating (for example, see Patent Document 1).

 (補強用パネル11,12)
 補強用パネルは、図2に示すように、第1(下側)補強用パネル11と、この第1補強用パネル11の上側に設けられた第2(上側)補強用パネル12とを備えている。第1補強用パネル11及び第2補強用パネル12は、いずれも鉄鋼製とされている。
(Reinforcing panels 11, 12)
As shown in FIG. 2, the reinforcing panel includes a first (lower) reinforcing panel 11 and a second (upper) reinforcing panel 12 provided on the upper side of the first reinforcing panel 11. Yes. Both the first reinforcing panel 11 and the second reinforcing panel 12 are made of steel.
 第1補強用パネル11は、車体前後方向の前側から後側に向かって順に、水平方向に延びる平坦部11aと、車体上下方向の下側へと屈曲して延びる屈曲部11bと、平坦部11aよりも車体上下方向の下側で水平方向に延びる平坦部11cとを有しており、これらが一体的に形成されている。また、平坦部11aには後述するボルト16が挿入されるための貫通孔11fが設けられている。さらに、平坦部11aの下側面には、貫通孔11fの外周に沿ってボルト16のネジ部16cに螺合する溶接ナット18が設けられている。 The first reinforcing panel 11 includes a flat portion 11a that extends in the horizontal direction, a bent portion 11b that extends by bending downward in the vertical direction of the vehicle body, and a flat portion 11a.

 [本実施形態の作用・効果]
 以上のように構成された本実施形態に係るアンカ板の回り止め構造1の作用・効果を図3A、3B及び図4A、4Bに基づいて説明する。
[Operation and effect of this embodiment]
The operation and effect of the anchor plate anti-rotation structure 1 according to this embodiment configured as described above will be described with reference to FIGS. 3A and 3B and FIGS.
 図3Bは、本実施形態のアンカ板10を備えておらず、アンカ板50を備えた回り止め構造である。アンカ板50は、平板部50aと、平板部10aの左右両端側から鉛直方向上側(即ち、紙面手前側)へ延びる一対の側壁部50bとを備え、平板部50aの中央部においてボルト16で平板面に固定されている。また、左右一対の側壁部50bには、右側のバックル21に取付けられたウェビング(ベルト)22、左側のバックル23に取付られたウェビング(ベルト)24がそれぞれ固定点Dで固定されている。さらに、車体前後方向の後側には、平板部50aに隣接して回転防止用のビード51が形成されている。上記構造においては、ウェビング22の固定点Dと、ボルト16の固定点Cと、ウェビング24の固定点Dとは、一直線上に位置している。このため、右側や左側から過度の力で引張られると、反動により固定点Cを中心として時計周りや反時計周りに回転し、ビード51を乗越えて回転することがあった。 FIG. 3B shows a detent structure provided with the anchor plate 50 without the anchor plate 10 of the present embodiment. The anchor plate 50 includes a flat plate portion 50a and a pair of side wall portions 50b extending from the left and right ends of the flat plate portion 10a to the upper side in the vertical direction (that is, the front side in the drawing). It is fixed to the surface. Further, a webbing (belt) 22 attached to the right buckle 21 and a webbing (belt) 24 attached to the left buckle 23 are fixed at a fixed point D to the pair of left and right side walls 50b. Further, a rotation preventing bead 51 is formed adjacent to the flat plate portion 50a on the rear side in the longitudinal direction of the vehicle body. In the above structure, the fixing point D of the webbing 22, the fixing point C of the bolt 16, and the fixing point D of the webbing 24 are located on a straight line. For this reason, when pulled with an excessive force from the right side or the left side, it may rotate clockwise or counterclockwise around the fixed point C due to the reaction, and may rotate over the bead 51.
 これに対し、図3Aに示す本実施形態に係るアンカ板の回り止め構造1においては、ウェビング22の固定点Bとウェビング24の固定点Bとを結ぶ線上からボルト16の固定点Aが外れており、ボルト16の固定点Aと、ウェビング22の固定点Bと、ウェビング24の固定点Bとは、一直線上に位置していない。このため、右側や左側から過度の力で引張られても、反動により固定点Aを中心として時計周りや反時計周りに回転することを防止できる。従って、アンカ板10の回転を確実に抑制することができる。 On the other hand, in the anchor plate detent structure 1 according to the present embodiment shown in FIG. 3A, the fixing point A of the bolt 16 is removed from the line connecting the fixing point B of the webbing 22 and the fixing point B of the webbing 24. The fixing point A of the bolt 16, the fixing point B of the webbing 22, and the fixing point B of the webbing 24 are not located on a straight line. For this reason, even if it is pulled with an excessive force from the right side or the left side, it can be prevented from rotating clockwise or counterclockwise around the fixed point A due to the reaction. Accordingly, the rotation of the anchor plate 10 can be reliably suppressed.
 また、図3Aに示す本実施形態に係るアンカ板の回り止め構造1では、アンカ板10の先端部10dが第2補強パネル12の回り止め部12b(図1,2参照)に当接することによって、回転を防止する。このため、図3Bに示すように、平坦部50aがビード51を乗越えて過度に回転することを抑制できる。従って、アンカ板10の回り止めを確実に行うことができる。 Further, in the anchor plate detent structure 1 according to the present embodiment shown in FIG. 3A, the tip 10d of the anchor plate 10 abuts against the detent portion 12b (see FIGS. 1 and 2) of the second reinforcing panel 12. Prevent rotation. For this reason, as shown to FIG. 3B, it can suppress that the flat part 50a gets over the bead 51 and rotates excessively. Therefore, the anchor plate 10 can be reliably prevented from rotating.
 次に、図4Bは、本実施形態のアンカ板10を備えておらず、側壁部50bを備えたアンカ板50の拡大図である。アンカ板50において、図中矢印で示すウェビング24の引張方向は、側壁部50bに形成された貫通孔55の長手方向に対して直交していない。このため、ウェビング24に掛かる引張力が貫通孔55の全体に均一に伝わらない。 Next, FIG. 4B is an enlarged view of the anchor plate 50 that does not include the anchor plate 10 of the present embodiment but includes the side wall portion 50b. In the anchor plate 50, the pulling direction of the webbing 24 indicated by an arrow in the drawing is not orthogonal to the longitudinal direction of the through hole 55 formed in the side wall 50b. For this reason, the tensile force applied to the webbing 24 is not uniformly transmitted to the entire through hole 55.
 これに対して、図4Aに示す本実施形態のアンカ板10において、図中矢印で示すウェビング24の引張方向は、側壁部10bに形成された貫通孔15の長手方向に対して直交している。このため、ウェビング24に掛かる引張力が貫通孔15の全体に均一に伝わることになる。 On the other hand, in the anchor plate 10 of the present embodiment shown in FIG. 4A, the pulling direction of the webbing 24 indicated by an arrow in the drawing is orthogonal to the longitudinal direction of the through hole 15 formed in the side wall portion 10b. . For this reason, the tensile force applied to the webbing 24 is uniformly transmitted to the entire through-hole 15.
