Description

シートベルト装置の取付構造Seat belt device mounting structure

　本発明は、改良されたシートベルト装置の取付構造に関する。 The present invention relates to an improved seat belt device mounting structure.

　車両用のシートベルト装置には、後部座席の中央に着座する乗員を拘束するためのものがある。このようなシートベルト装置として、例えば下記の特許文献１に記載された技術が知られている。 There is a vehicle seat belt device for restraining an occupant seated in the center of the rear seat. As such a seat belt device, for example, a technique described in Patent Document 1 below is known.

　特許文献１に記載のシートベルト装置では、ウェビングベルトを巻き取るリトラクタは、車体の天井部の下方に配置されブラケットを介して天井部に取り付けられている。ウェビングベルトをガイドするベルトガイドは、リトラクタよりも前方に位置する。乗員は、頭部の斜め後方から下方に向かって、上半身を横断するようにウェビングベルトを掛け渡し、腰付近に位置するバックルにタングを嵌合させる。ウェビングベルトはリトラクタとバックルとの間に張られ、乗員は座席に拘束される。 In the seat belt device described in Patent Document 1, the retractor that winds the webbing belt is disposed below the ceiling of the vehicle body and attached to the ceiling via a bracket. The belt guide for guiding the webbing belt is located in front of the retractor. The occupant hangs the webbing belt so as to cross the upper body from the diagonally rear of the head downward, and fits the tongue to the buckle located near the waist. The webbing belt is stretched between the retractor and the buckle, and the occupant is restrained by the seat.

　車両の衝突時、リトラクタはウェビングベルトが引き出されることを防止し、前方に移動しようとする乗員を抑える。そのため、リトラクタには前方に引っ張られる力が加わる。 In the event of a vehicle collision, the retractor prevents the webbing belt from being pulled out, and suppresses passengers trying to move forward. Therefore, a force that is pulled forward is applied to the retractor.

　ここで、特許文献１のリトラクタは、ブラケットを天井部に重ね合わせ、ボルトを下方から上方に向かって挿通することにより、車体に固定されている。そのため、リトラクタが引っ張られる力の一部はボルトの軸に直交する。結果、ボルトの軸にはせん断力が加わる。 Here, the retractor of Patent Document 1 is fixed to the vehicle body by superimposing the bracket on the ceiling and inserting the bolt upward from below. Therefore, a part of the force with which the retractor is pulled is perpendicular to the bolt axis. As a result, a shearing force is applied to the bolt shaft.

特開２００９－２８０１５３号公報JP 2009-280153 A

　本発明は、高い取付強度を得ることのできるシートベルト装置の取付構造の提供を課題とする。 An object of the present invention is to provide a seat belt device mounting structure capable of obtaining a high mounting strength.

　本発明によれば、ウェビングベルトを巻き取り可能なリトラクタ、及び、前記ウェビングベルトをガイドするベルトガイドがブラケットを介して車体上部に取り付けられたシートベルト装置の取付構造において、
　前記ベルトガイドは、前記リトラクタよりも前方、且つ、車幅中心側に位置し、
　前記ブラケットには、側部取付部と、後部取付部とが形成され、
　前記ブラケットは、前記側部取付部において車体側部に取り付けられていると共に、前記後部取付部において車体後部に取り付けられていることを特徴とするシートベルト装置の取付構造。 According to the present invention, in the mounting structure of the seat belt device in which the retractor capable of winding the webbing belt and the belt guide for guiding the webbing belt is mounted to the upper part of the vehicle body via the bracket,
The belt guide is located in front of the retractor and on the vehicle width center side,
The bracket is formed with a side mounting portion and a rear mounting portion,
The bracket is attached to a vehicle body side portion at the side portion attachment portion, and is attached to a vehicle body rear portion at the rear portion attachment portion.

　好ましくは、前記側部取付部は、前記車体側部の上部から車幅方向に延びるルーフアーチの下端に近接して、且つ、前記ブラケットの前後方向の異なる２箇所に形成され、
　前方に形成された前記側部取付部は、前記ルーフアーチよりも前方に位置し、
　後方に形成された前記側部取付部は、前記ルーフアーチよりも後方に位置する。 Preferably, the side attachment portion is formed in two different locations in the front-rear direction of the bracket, close to the lower end of the roof arch extending in the vehicle width direction from the upper portion of the vehicle body side portion,
The side attachment portion formed forward is located forward of the roof arch,
The side attachment portion formed at the rear is located behind the roof arch.

　本発明では、リトラクタ及びベルトガイドを車体上部に取り付けるブラケットには、側部取付部と、後部取付部とが形成されている。ブラケットは、側部取付部において車体側部に取り付けられていると共に、後部取付部において車体後部に取り付けられている。 In the present invention, the bracket for attaching the retractor and the belt guide to the upper portion of the vehicle body is formed with a side attachment portion and a rear attachment portion. The bracket is attached to the vehicle body side portion at the side attachment portion, and is attached to the vehicle body rear portion at the rear attachment portion.

　車両の衝突時、前方に移動しようとする乗員によりウェビングベルトは引っ張られる。ウェビングベルトを引っ張る力は、ベルトガイド及びリトラクタを介し、ブラケットに形成された側部取付部と後部取付部に伝わる。この力の一部は、側部取付部と後部取付部を前方に引っ張る力として加わる。詳細には、側部取付部は、車体の側部方向を向いて形成されているため、前方に引っ張る力は、せん断力として側部取付部に加わる。一方、後部取付部は、車体の後部方向に向いて形成されているため、前方に引っ張る力は、引張力として後部取付部に加わる。 When the vehicle collides, the webbing belt is pulled by the occupant trying to move forward. The force pulling the webbing belt is transmitted to the side attachment portion and the rear attachment portion formed on the bracket via the belt guide and the retractor. A part of this force is applied as a force pulling the side attachment portion and the rear attachment portion forward. In detail, since the side part attaching part is formed facing the side part direction of the vehicle body, the force pulling forward is applied to the side part attaching part as a shearing force. On the other hand, since the rear attachment portion is formed toward the rear portion of the vehicle body, the force pulling forward is applied to the rear attachment portion as a tensile force.

　すなわち、本発明によるシートベルト装置の取付構造では、車両の衝突時において、リトラクタを車体に取り付ける取付部の一部に、引張力が加わる構造となっている。衝突時において、取付部のすべてにせん断力が加わる構造と比較すると、本発明によるシートベルト装置は高い取り付け強度を得ることができる。 That is, the seat belt device mounting structure according to the present invention has a structure in which a tensile force is applied to a part of the mounting portion for mounting the retractor to the vehicle body in the event of a vehicle collision. Compared with a structure in which a shearing force is applied to all of the attachment portions at the time of collision, the seat belt device according to the present invention can obtain a high attachment strength.

　さらに、本発明では、ルーフアーチの下端は、車体側部の上部から延びている。そして、側部取付部は、ルーフアーチの下端に近接して、ブラケットの前後方向の異なる２箇所に位置するように形成される。 Furthermore, in the present invention, the lower end of the roof arch extends from the upper part of the side part of the vehicle body. And a side part attaching part is formed so that it may adjoin to the lower end of a roof arch, and may be located in two places where the front-back direction of a bracket differs.

　すなわち、車体側部の上部のうち、ルーフアーチの下端の近傍の強度は高くなる。そして、この強度の高い部位の近傍に、２箇所に形成された側部取付部が位置する。よって、車体側部に対するブラケットの取付強度は高くなる。 That is, the strength near the lower end of the roof arch in the upper part of the side of the vehicle body is increased. And the side part attachment part formed in two places is located in the vicinity of this high intensity | strength site | part. Therefore, the mounting strength of the bracket to the vehicle body side portion is increased.

　リトラクタ６０は、リトラクタ本体部６１が略直方体形状を呈する。リトラクタ本体部６１の前面部６２の上部には、凸部６２ａが形成されている。この凸部６２ａとリトラクタ本体部６１の上面部６３を覆うように、Ｌ字形状を呈するカバー６４が取り付けられている。カバー６４とリトラクタ本体部６１の前面部６２との間には隙間が形成される。カバー６４には、ウェビングベルト３２が通される矩形状の開口部６４ａが形成されている。 In the retractor 60, the retractor main body 61 has a substantially rectangular parallelepiped shape. A convex portion 62 a is formed on the upper portion of the front surface portion 62 of the retractor main body portion 61. An L-shaped cover 64 is attached so as to cover the convex portion 62 a and the upper surface portion 63 of the retractor main body portion 61. A gap is formed between the cover 64 and the front surface portion 62 of the retractor main body 61. The cover 64 is formed with a rectangular opening 64a through which the webbing belt 32 passes.

　側部ブラケット４０は、１枚の金属により形成されており、概ね車体側部（図１、符号１４）に沿って延びる側部ブラケット本体部４１と、この側部ブラケット本体部４１の後端から車幅中央に向かって折り曲げられた側部ブラケット後面部４２と、からなる。 The side bracket 40 is formed of a single piece of metal, and extends from the side bracket main body 41 extending substantially along the vehicle body side (see reference numeral 14 in FIG. 1) and the rear end of the side bracket main body 41. And a side bracket rear surface portion 42 bent toward the center of the vehicle width.

　側部ブラケット本体部４１は、前方から後方に延び、下方に延びた後さらに後方に延びている。 The side bracket body 41 extends rearward from the front, extends downward, and further extends rearward.

　ベルトガイド３３は、側部ブラケット本体部４１に一体的に、車幅中央に向かって延びるように形成されている。ベルトガイド３３には、ウェビングベルト３２を通すための矩形状のガイド孔３３ａが形成されている。 The belt guide 33 is formed integrally with the side bracket main body 41 so as to extend toward the center of the vehicle width. The belt guide 33 is formed with a rectangular guide hole 33a through which the webbing belt 32 is passed.

　側部ブラケット本体部４１の前端には、前部ボルト孔４３（側部取付部４３）が形成されており、この前部ボルト孔４３に第１ボルト７１が取り付けられる。また、側部ブラケット本体部４１の中央にも中央部ボルト孔４４（側部取付部４４）が形成されており、この中央部ボルト孔４４に第２ボルト７２が取り付けられる。 A front bolt hole 43 (side attachment portion 43) is formed at the front end of the side bracket body portion 41, and the first bolt 71 is attached to the front bolt hole 43. A central bolt hole 44 (side mounting portion 44) is also formed at the center of the side bracket body 41, and the second bolt 72 is attached to the central bolt hole 44.

　側部ブラケット４０は、側部ブラケット後面部４２を下方から上方に向かって、カバー６４とリトラクタ本体部６１の前面部６２との隙間にスライドさせることによって、リトラクタ６０に取り付けられる。 The side bracket 40 is attached to the retractor 60 by sliding the side bracket rear surface portion 42 from below to the gap between the cover 64 and the front surface portion 62 of the retractor main body 61.

　後部ブラケット５０は、板状の後部ブラケット上面部５１と、この後部ブラケット上面部５１から車幅中央に向かって延び、連続して形成される後部ブラケット本体部５２とからなる。 The rear bracket 50 includes a plate-shaped rear bracket upper surface portion 51 and a rear bracket main body portion 52 that extends from the rear bracket upper surface portion 51 toward the vehicle width center and is continuously formed.

　後部ブラケット上面部５１の両端は、下方に向かって延び、その後、対向するように内側に延びる。そのため、両端には溝部５１ａ，５１ａが形成される。後部ブラケット５０は、左右の溝部５１ａ，５１ａの間にカバー６４が位置するように後部ブラケット上面部５１を配置し、後部ブラケット上面部５１を前方にスライドさせることにより、リトラクタ６０に取り付けられる。後部ブラケット上面部５１とカバー６４とは４つのネジ５１ｂにより固定される。後部ブラケット本体部５２には後部ボルト孔５３（後部取付部５３）が形成されており、この後部ボルト孔５３に第３ボルト７３が取り付けられる。 Both ends of the rear bracket upper surface portion 51 extend downward, and then extend inward so as to face each other. Therefore, groove portions 51a and 51a are formed at both ends. The rear bracket 50 is attached to the retractor 60 by arranging the rear bracket upper surface portion 51 so that the cover 64 is positioned between the left and right groove portions 51a, 51a and sliding the rear bracket upper surface portion 51 forward. The rear bracket upper surface 51 and the cover 64 are fixed by four screws 51b. A rear bolt hole 53 (rear mounting portion 53) is formed in the rear bracket main body portion 52, and a third bolt 73 is attached to the rear bolt hole 53.

　次に、リトラクタ６０の車体１２への取り付けについて説明する。
　図３を参照する。車体側部１４への、側部ブラケット４０の取り付けの説明をする。リトラクタ６０は、車体天井部１６の近傍に配置される。側部ブラケット４０は第１ボルト７１と第２ボルト７２とにより、車体側部１４に取り付けられる。そのため、第１ボルト７１及び第２ボルト７２の軸は、車幅方向を向く。また、ベルトガイド３３は、リトラクタ６０よりも前方に位置する。 Next, attachment of the retractor 60 to the vehicle body 12 will be described.
Please refer to FIG. The attachment of the side bracket 40 to the vehicle body side portion 14 will be described. The retractor 60 is disposed in the vicinity of the vehicle body ceiling portion 16. The side bracket 40 is attached to the vehicle body side portion 14 by a first bolt 71 and a second bolt 72. Therefore, the shafts of the first bolt 71 and the second bolt 72 are directed in the vehicle width direction. Further, the belt guide 33 is located in front of the retractor 60.

　次に図４を参照する。リヤピラー１９への、後部ブラケット５０の取り付けを説明する。後部ブラケット５０は、リヤピラー１９のなかの前方を向いている面に取り付けられる。この面を、適宜「取付面部１９ａ」という。後部ブラケット５０は、第３ボルト７３により、車幅方向に延びる取付面部１９ａに取り付けられる。そのため、第３ボルト７３の軸は、車両１０の後方を向く。さらに、第３ボルト７３は、リトラクタ６０よりも車幅中央側に位置する。 Next, refer to FIG. The attachment of the rear bracket 50 to the rear pillar 19 will be described. The rear bracket 50 is attached to a surface of the rear pillar 19 facing forward. This surface is referred to as “mounting surface portion 19a” as appropriate. The rear bracket 50 is attached to the attachment surface portion 19 a extending in the vehicle width direction by the third bolt 73. Therefore, the axis of the third bolt 73 faces the rear of the vehicle 10. Further, the third bolt 73 is located on the vehicle width center side with respect to the retractor 60.

　ここで、ベルトガイド３３は、リトラクタ６０よりも車幅中心側に位置する。結果、ベルトガイド３３の開口部３３ａを通過するウェビングベルト３２は、前方、かつ、車幅中心に向かって引き出し可能である。 Here, the belt guide 33 is located closer to the center of the vehicle width than the retractor 60. As a result, the webbing belt 32 passing through the opening 33a of the belt guide 33 can be pulled out forward and toward the vehicle width center.

　また、車体側部１４の上部には、車幅方向に延びるルーフアーチ８１が設けられている。このルーフアーチ８１の下端の近傍には、第１ボルト７１（前部ボルト孔４３）及び第２ボルト７２（中央部ボルト孔４４）が位置する。詳細には、図３に示されるように、ルーフアーチ８１の前方に第１ボルト７１（前部ボルト孔４３）が位置し、ルーフアーチ８１の後方に第２ボルト７２（中央部ボルト孔４４）が位置する。さらに、これら第１ボルト７１（前部ボルト孔４３）と第２ボルト７２（中央部ボルト孔４４）との間にはベルトガイド３３が位置する。 Further, a roof arch 81 extending in the vehicle width direction is provided on the upper portion of the vehicle body side portion 14. In the vicinity of the lower end of the roof arch 81, a first bolt 71 (front bolt hole 43) and a second bolt 72 (center bolt hole 44) are located. Specifically, as shown in FIG. 3, the first bolt 71 (front bolt hole 43) is located in front of the roof arch 81, and the second bolt 72 (center bolt hole 44) is located behind the roof arch 81. Is located. Further, the belt guide 33 is positioned between the first bolt 71 (front bolt hole 43) and the second bolt 72 (center bolt hole 44).

　次に、シートベルト装置３０の取付構造の作用及び効果について説明する。
　図５を参照する。後部シート２０の中央に着座する乗員Ｍｎは、頭部の斜め後方から下方に向かって、上半身を横断するようにウェビングベルト３２を掛け渡し、腰付近に位置するバックル３５にタング３４を挿入する。ウェビングベルト３２はリトラクタ６０とバックル３５との間に張られ、乗員Ｍｎは座席に拘束される。車両１０の衝突時、乗員Ｍｎは前方に移動しようとするため、ウェビングベルト３２は前方に引っ張られる。ウェビングベルト３２を引っ張る力はウェビングベルト３２を介して、リトラクタ６０とこのリトラクタ６０に取り付けられた側部ブラケット４０及び後部ブラケット５０に伝わる。 Next, the operation and effect of the mounting structure of the seat belt device 30 will be described.
Please refer to FIG. The occupant Mn sitting at the center of the rear seat 20 hangs the webbing belt 32 so as to cross the upper body from obliquely rearward to the lower part of the head, and inserts the tongue 34 into the buckle 35 located near the waist. The webbing belt 32 is stretched between the retractor 60 and the buckle 35, and the occupant Mn is restrained by the seat. When the vehicle 10 collides, the occupant Mn tries to move forward, so that the webbing belt 32 is pulled forward. The pulling force of the webbing belt 32 is transmitted to the retractor 60 and the side bracket 40 and the rear bracket 50 attached to the retractor 60 via the webbing belt 32.

　図６に示されるように、衝突時には、ウェビングベルト３２が延びる方向に力が伝わる。この力は、平面視において、前方に向かう力と車幅中央に向かう力に分解される。このとき、乗員Ｍｎは前方に移動しようとするため、特に前方に向かう力が大きくなる。 As shown in FIG. 6, at the time of collision, the force is transmitted in the direction in which the webbing belt 32 extends. This force is decomposed into a force toward the front and a force toward the center of the vehicle width in plan view. At this time, since the occupant Mn tries to move forward, the force toward the front is particularly large.

　この前方に向かう力は、側部ブラケット４０及び後部ブラケット５０を介して、第１ボルト７１～第３ボルト７３に伝わる。上記の通り、車体側部１４に取り付けられた第１ボルト７１，第２ボルト７２の軸は、車幅方向を向いている。そのため前方に向かう力は、第１ボルト７１，第２ボルト７２の軸にせん断力として加わる。一方、取付面部１９ａに取り付けられた第３ボルト７３は、車両の後方を向いている。そのため、前方に向かう力は、第３ボルト７３には、引張力として伝わる。 The forward force is transmitted to the first bolt 71 to the third bolt 73 through the side bracket 40 and the rear bracket 50. As described above, the shafts of the first bolt 71 and the second bolt 72 attached to the vehicle body side portion 14 face the vehicle width direction. Therefore, the forward force is applied as a shearing force to the shafts of the first bolt 71 and the second bolt 72. On the other hand, the 3rd volt | bolt 73 attached to the attachment surface part 19a has faced the back of the vehicle. Therefore, the forward force is transmitted to the third bolt 73 as a tensile force.

　すなわち、本発明によるシートベルト装置３０の取付構造では、車両１０の衝突時において、第３ボルト７３の軸にはせん断力でなく、引張力が加わる。仮に、第３ボルト７３も車体側部１４に取り付けられている場合、衝突時において、第１～第３ボルト７１，７２，７３のすべてにせん断力が加わってしまう。しかし、衝突時に引張力が加わるボルトを含んだ構造であれば、シートベルト装置３０は高い取り付け強度を得ることができる。 That is, in the mounting structure for the seat belt device 30 according to the present invention, a tensile force is applied to the shaft of the third bolt 73 instead of a shearing force when the vehicle 10 collides. If the third bolt 73 is also attached to the vehicle body side portion 14, a shearing force is applied to all of the first to third bolts 71, 72, 73 at the time of a collision. However, if the structure includes a bolt to which a tensile force is applied at the time of collision, the seat belt device 30 can obtain a high mounting strength.

　再び、図５に戻る。乗員Ｍｎがウェビングベルト３２を着用している時、ウェビングベルト３２は、リトラクタ６０からベルトガイド３３までは上方に延び、リトラクタ６０からバックル３５までは下方に延びる。そのため、衝突時には、リトラクタ６０及びブラケット３１には上下方向の力も加わる。この力は、第１ボルト７１，第２ボルト７２の軸をたわませる力となる。ここで、図６も併せて参照すると、後部ブラケット５０は、車幅方向、すなわち第１ボルト７１，第２ボルト７２の軸方向に延びており、第３ボルト７３によってリヤピラー１９に取り付けられている。上下方向に働く力は、車幅方向に延びた後部ブラケット５０にも支えられるため、第１ボルト７１，第２ボルト７２はたわみにくくなる。 Again, return to FIG. When the occupant Mn wears the webbing belt 32, the webbing belt 32 extends upward from the retractor 60 to the belt guide 33 and extends downward from the retractor 60 to the buckle 35. Therefore, a vertical force is also applied to the retractor 60 and the bracket 31 during a collision. This force is a force that causes the shafts of the first bolt 71 and the second bolt 72 to bend. Here, referring also to FIG. 6, the rear bracket 50 extends in the vehicle width direction, that is, the axial direction of the first bolt 71 and the second bolt 72, and is attached to the rear pillar 19 by the third bolt 73. . Since the force acting in the vertical direction is also supported by the rear bracket 50 extending in the vehicle width direction, the first bolt 71 and the second bolt 72 are less likely to bend.

　特に、本実施例では、後部ボルト孔５３は、リトラクタ６０よりも車幅中央側に位置している。例えば、後部ボルト穴５３がより車体側部１４側に形成されている場合と比較すると、第１ボルト７１，第２ボルト７２はたわみにくい。 In particular, in this embodiment, the rear bolt hole 53 is located on the vehicle width center side with respect to the retractor 60. For example, the first bolt 71 and the second bolt 72 are less likely to bend as compared with the case where the rear bolt hole 53 is further formed on the vehicle body side portion 14 side.

　さらに、本実施例では、図７に示されるように、車体側部１４の上部のうち、ルーフアーチ８１の下端の近傍の強度は高くなる。このルーフアーチ８１の下端の近傍には、ルーフアーチ８１の前方に前部ボルト孔４３が位置し、ルーフアーチ８１の後方に中央部ボルト孔４４が位置する。そのため、側部ブラケット４０は、車体側部１４のうちの強度の高くなる部位に対して第１ボルト７１及び第２ボルト７２により固定される。よって、車体側部１４に対する側部ブラケット４０の取付強度は高くなる。 Furthermore, in this embodiment, as shown in FIG. 7, the strength in the vicinity of the lower end of the roof arch 81 in the upper portion of the vehicle body side portion 14 is increased. Near the lower end of the roof arch 81, the front bolt hole 43 is located in front of the roof arch 81, and the central bolt hole 44 is located behind the roof arch 81. Therefore, the side bracket 40 is fixed to the portion of the vehicle body side portion 14 where the strength is increased by the first bolt 71 and the second bolt 72. Therefore, the attachment strength of the side bracket 40 to the vehicle body side portion 14 is increased.

　さらに、これら前部ボルト孔４３と中央部ボルト孔４４との間にはベルトガイド３３が位置する。そのため、ベルトガイド３３が前部ボルト孔４３の前方に位置している場合や、ベルトガイド３３が中央部ボルト孔４４の後方に位置している場合と比べると、取付強度は高くなる。 Further, a belt guide 33 is located between the front bolt hole 43 and the central bolt hole 44. Therefore, compared with the case where the belt guide 33 is located in front of the front bolt hole 43 and the case where the belt guide 33 is located behind the central bolt hole 44, the mounting strength is increased.

　なお、本実施例によるシートベルト装置３０は、後部座席の中央に着座する乗員が装着するためものに限られない。後部座席の左又は右に着座する乗員が装着することも可能である。また、ブラケット３１は、車体１２に対して第１ボルト～第３ボルト７１，７２，７３を用いて取り付けられているが、溶接により車体１２と接合されてもよい。また、後部ブラケット５０は、リヤピラー１９のなかの前方を向いている取付面部１９ａに取り付けられたが、例えば、車体側部１４の一部が車幅方向に延びた部位などに取り付けてもよい。 It should be noted that the seat belt device 30 according to the present embodiment is not limited to being worn by an occupant seated in the center of the rear seat. It can also be worn by an occupant seated on the left or right of the rear seat. The bracket 31 is attached to the vehicle body 12 using the first to third bolts 71, 72, 73, but may be joined to the vehicle body 12 by welding. The rear bracket 50 is attached to the attachment surface portion 19a facing forward in the rear pillar 19, but may be attached to, for example, a portion where a part of the vehicle body side portion 14 extends in the vehicle width direction.

　さらに、ブラケット３１は、リトラクタ６０と分けて形成されているが、リトラクタ６０と一体的に形成されていてもよい。また、側部ブラケット４０は、一体的に形成されているが、より汎用的な形状のブラケットを用いてもよい。例えば、Ｌ字形状を呈するブラケットと、Ｉ字形状を呈するブラケットを組み合わせることもできる。 Furthermore, although the bracket 31 is formed separately from the retractor 60, it may be formed integrally with the retractor 60. Moreover, although the side bracket 40 is integrally formed, a bracket having a more general shape may be used. For example, a bracket exhibiting an L shape and a bracket exhibiting an I shape can be combined.

　本発明のシートベルト装置は、乗用車に搭載するのに好適である。 The seat belt device of the present invention is suitable for mounting on a passenger car.
