Description

この発明は乗物用シートのシートベルト装置とベルト案内部材に関する。   The present invention relates to a seat belt device for a vehicle seat and a belt guide member.

乗物用シートに着座している着座者を保護するためのシートベルト装置において、ベルト幅を広げて衝撃を緩和するように構成したものが知られている（例えば、特許文献１参照）。
特許文献１に開示されたシートベルト装置においては、着座者の肩部後方位置に配設されるガイド部材によってシートベルトが巻取装置に向けて案内される。
ガイド部材は、そのシートベルトを案内するガイド面が当該シートベルトの幅方向両側を湾曲させて折り返すことのできる断面Ｃ字形状の湾曲案内部が対向して配置された形態として構成されており、該湾曲案内部の幅方向の配置間隔はシートベルトを収納装置に収納する方向に向けて漸次幅狭とされている。 2. Description of the Related Art A seat belt device for protecting a seated person seated on a vehicle seat is known in which a belt width is widened to reduce an impact (see, for example, Patent Document 1).
In the seat belt device disclosed in Patent Document 1, the seat belt is guided toward the take-up device by a guide member disposed at the shoulder rear position of the seated person.
The guide member is configured as a configuration in which a guide surface that guides the seat belt is arranged so as to face the curved guide portions having a C-shaped cross section that can be bent by bending both sides in the width direction of the seat belt. The interval in the width direction between the curved guide portions is gradually narrowed in the direction in which the seat belt is stored in the storage device.

特開２０１２−２４０４３２号公報JP 2012-240432 A

ところで、特許文献１に開示されたシートベルト装置においては、シートベルトの巻き取り時には、ガイド部材の断面Ｃ字形状の湾曲案内部に案内されてシートベルトが幅狭となる。また、シートベルトの巻き取り時には、シートベルトがガイド部材を通過して引き出されることでシートベルト自身の復元力によって幅広となる。
このため、ガイド部材に案内されてシートベルトが幅狭となった後、ガイド部材と収納装置（巻取装置）との間の距離が長く設定されていると、ガイド部材と収納装置との間において、シートベルト自体の復元力によって幅広となることが想定される。この場合、シートベルトが幅広状態で巻取られようとし、巻き取り不良が発生する恐れがある。 By the way, in the seat belt device disclosed in Patent Document 1, when the seat belt is wound, the seat belt is narrowed by being guided by the curved guide portion having a C-shaped cross section of the guide member. Further, when the seat belt is retracted, the seat belt is pulled out through the guide member, so that the seat belt is widened by the restoring force of the seat belt itself.
For this reason, if the distance between the guide member and the storage device (winding device) is set long after being guided by the guide member and the seat belt is narrowed, the distance between the guide member and the storage device In this case, it is assumed that the width is widened by the restoring force of the seat belt itself. In this case, the seat belt tends to be wound in a wide state, which may cause a winding failure.

この発明の目的は、前記問題点に鑑み、ベルト体を引き出して使用するときには、ベルト体のベルト幅を広げ、ベルト体を巻き取るときには、ベルト体を幅狭の状態で良好に巻き取ることができるシートベルト装置とベルト案内部材を提供することである。   In view of the above problems, the object of the present invention is to widen the belt width of the belt body when the belt body is pulled out and used, and to wind the belt body in a narrow state when winding the belt body. It is to provide a seat belt device and a belt guide member.

前記課題を解決するために、この発明の第１の発明に係るシートベルト装置は、乗物用シートのシートベルト装置であって、
一端部が巻取装置に引出し可能に巻き取られ、他端部がアンカに固定されるベルト体は、長尺で幅広の帯状体と、この帯状体の幅方向両縁部の長手方向に沿って配設されたファスナとを備え、
前記ベルト体の引出し経路上には、前記ベルト体を引出し及び巻取り案内する挿通孔を有するベルト案内部材が配設され、
前記ベルト案内部材の挿通孔よりもベルト巻取側に位置する部分には、前記ファスナを開閉するスライダが装着されるスライダ支持体が配設され、
前記ベルト体の引出し時には、前記スライダによって前記ファスナが開かれた後、前記ベルト案内部材の挿通孔に挿通されて引き出し案内され、
前記ベルト体の巻取り時には、前記ベルト案内部材の挿通孔に挿通されて巻き取り案内された後、前記スライダによって前記ファスナが閉じられることで幅狭のチューブ状をなすことを特徴とする。 In order to solve the above problems, a seat belt device according to a first aspect of the present invention is a seat belt device for a vehicle seat,
The belt body in which one end portion is wound so as to be able to be pulled out by the winding device and the other end portion is fixed to the anchor is a long and wide belt-like body, and the longitudinal direction of both edges in the width direction of the belt-like body. And fasteners arranged
A belt guide member having an insertion hole for drawing and winding the belt body is disposed on the belt body drawing path.
A slider support to which a slider for opening and closing the fastener is mounted is disposed in a portion located on the belt winding side from the insertion hole of the belt guide member,
When the belt body is pulled out, after the fastener is opened by the slider, the belt body is inserted and guided through the insertion hole of the belt guide member,
At the time of winding the belt body, the belt body is inserted into the insertion hole of the belt guide member and guided by winding, and then the fastener is closed by the slider to form a narrow tube shape.

第１の発明によると、ベルト体を引き出して使用する場合、巻取装置側のベルト体がスライダを通過する際、スライダによってファスナが開かれる。その後、ベルト体は、ベルト案内部材の挿通孔を経て引き出される。すると、ベルト体は、自身の復元力によって幅広に展開される。
このため、乗物用シートに着座している着座者は、幅広に展開されたベルト体によって保護される。
ベルト体を巻き取って格納する場合、幅広に展開されたベルト体がベルト案内部材の挿通孔を経てスライダを通過する際、スライダによってファスナが閉じられ、幅狭のチューブ状をなす。このため、ベルト体を巻き取り不良なく良好に巻き取ることができる。 According to the first invention, when the belt body is pulled out and used, when the belt body on the winding device side passes through the slider, the fastener is opened by the slider. Thereafter, the belt body is pulled out through the insertion hole of the belt guide member. Then, the belt body is expanded widely by its own restoring force.
For this reason, the seated person seated on the vehicle seat is protected by the belt body that is widened.
When the belt body is wound and stored, when the wide belt body passes through the slider through the insertion hole of the belt guide member, the fastener is closed by the slider to form a narrow tube shape. For this reason, a belt body can be wound up satisfactorily without winding failure.

図４と図５に示すように、ベルト体５０は、長尺で幅広の帯状体５１と、この幅広の帯状体５１の幅方向両縁部の長手方向に沿って配設されたファスナ６０とを備えている。
この実施例１において、シートベルト装置の使用状態において、ベルト体５０の着座者の胸部及びその近傍を支承する部分に対し、ファスナ６０の一対のテープ６１がミシン縫い等によって縫い合わされて配設され、その他の部分においては、幅広の帯状体５１の幅方向両縁部がミシン縫い等によって縫い合わされてチューブ状をなしている。なお、一対のテープ６１には相互に噛み合うエレメント６２がそれぞれ配設されている。 As shown in FIGS. 4 and 5, the belt body 50 includes a long and wide belt-like body 51, and a fastener 60 disposed along the longitudinal direction of both edges in the width direction of the wide belt-like body 51. It has.
In the first embodiment, the pair of tapes 61 of the fastener 60 are sewn together by sewing or the like on the chest of the seated person and the part supporting the vicinity thereof when the seat belt device is in use. In other parts, both edges in the width direction of the wide belt-like body 51 are sewn together by sewing or the like to form a tube. The pair of tapes 61 are provided with elements 62 that mesh with each other.

図１〜図３に示すように、ベルト案内部材１１の挿通孔１４よりもベルト巻取側に位置する部分には、ファスナ６０の両エレメント６２を噛み合わせたり、あるいは解放してファスナ６０を開閉するスライダ６３が装着されるスライダ支持体７０が配設されている。   As shown in FIG. 1 to FIG. 3, the fastener 60 is opened or closed by engaging or releasing both elements 62 of the fastener 60 at a portion of the belt guide member 11 located on the belt winding side with respect to the insertion hole 14. A slider support 70 on which the slider 63 is mounted is disposed.

この実施例１において、スライダ支持体７０は、ベルト案内部材１１とは別個に形成されて、車体側部材としてのピラー部の上部近傍に取り付けられている。
また、スライダ支持体７０は、ベルト案内部材１１と共通の取付軸１９によって、車体側部材に取り付けられ、ベルト案内部材１１とは相対的に回動可能である。
すなわち、図２と図３に示すように、スライダ支持体７０は、取付軸１９が挿通される取付孔を有するボス部７１と、このボス部７１から下向きに延出された支持部７２とを一体に有している。
さらに、支持部７２の先端部（下端部）には、スライダ６３が、その胴体部６４から突出された柱部６５において一体状に装着されている。
そして、ベルト体５０の引出し時には、スライダ６３によってファスナ６０が開かれた後、ベルト案内部材１１の挿通孔１４に挿通されて引き出し案内される。
また、ベルト体５０の巻取り時には、ベルト案内部材１１の挿通孔１４に挿通されて巻き取り案内された後、スライダ６３によってファスナ６０が閉じられることで幅狭のチューブ状をなし、巻取装置１０に巻き取られるようになっている。 In the first embodiment, the slider support 70 is formed separately from the belt guide member 11 and is attached in the vicinity of the upper portion of the pillar portion as the vehicle body side member.
The slider support 70 is attached to the vehicle body side member by an attachment shaft 19 common to the belt guide member 11, and is rotatable relative to the belt guide member 11.
That is, as shown in FIGS. 2 and 3, the slider support body 70 includes a boss portion 71 having an attachment hole through which the attachment shaft 19 is inserted, and a support portion 72 extending downward from the boss portion 71. It has one.
Further, a slider 63 is integrally attached to a distal end portion (lower end portion) of the support portion 72 at a column portion 65 protruding from the body portion 64.
When the belt body 50 is pulled out, the fastener 60 is opened by the slider 63, and then inserted through the insertion hole 14 of the belt guide member 11 to be guided out.
When the belt body 50 is wound, the belt 60 is inserted into the insertion hole 14 of the belt guide member 11 and guided to be wound, and then the fastener 60 is closed by the slider 63 to form a narrow tube. 10 is wound up.

この実施例１に係るシートベルト装置は上述したように構成される。
したがって、ベルト体５０を引き出して使用する場合、巻取装置１０側に位置するベルト体５０がファスナ６０のスライダ６３を通過する際、スライダ６３によってファスナ６０が開かれた後、ベルト案内部材１１の挿通孔１４を経て引き出される。すると、ベルト体５０は、自身の復元力によって幅広に展開される。
このため、乗物用シートに着座している着座者は、幅広に展開されたベルト体５０によって保護される。 The seat belt device according to the first embodiment is configured as described above.
Therefore, when the belt body 50 is pulled out and used, when the belt body 50 located on the winding device 10 side passes through the slider 63 of the fastener 60, the fastener 60 is opened by the slider 63, and then the belt guide member 11. It is pulled out through the insertion hole 14. Then, the belt body 50 is expanded widely by its own restoring force.
For this reason, the seated person seated on the vehicle seat is protected by the belt body 50 that is widened.

ベルト体５０を巻き取って格納する場合、幅広に展開されたベルト体５０がベルト案内部材１１の挿通孔１４を経てファスナ６０のスライダ６３を通過する際、スライダ６３によってファスナ６０が閉じられ、幅狭のチューブ状をなす。このため、ベルト体５０を巻取装置１０によって巻き取り不良なく良好に巻き取ることができる。
また、ベルト体５０は、幅狭のチューブ状をなすため、幅広のベルト体５０の幅寸法に対応して巻取装置１０を大型化する必要もない。 When the belt body 50 is wound and stored, when the wide belt body 50 passes through the slider 63 of the fastener 60 through the insertion hole 14 of the belt guide member 11, the fastener 60 is closed by the slider 63, and the width Forms a narrow tube. For this reason, the belt body 50 can be wound up well by the winding device 10 without winding failure.
Further, since the belt body 50 has a narrow tube shape, it is not necessary to increase the size of the winding device 10 corresponding to the width dimension of the wide belt body 50.

また、この実施例１において、例えば、図７と図８に示すように、着座者によるベルト体５０の引出方向が、斜めとなって引き出された場合、ベルト体５０の引出方向に追従してベルト案内部材１１が取付軸１９を中心としてベルト体５０の引出方向に沿って回動する。   Further, in the first embodiment, for example, as shown in FIGS. 7 and 8, when the pulling direction of the belt body 50 by the seated person is pulled obliquely, the belt body 50 follows the pulling direction. The belt guide member 11 rotates about the attachment shaft 19 along the pull-out direction of the belt body 50.

一方、スライダ支持体７０は、ベルト案内部材１１とは別個に形成されてベルト案内部材１１の挿通孔１４よりもベルト巻取側に位置する部分に配設される。
このため、ベルト案内部材１１が取付軸１９を中心としてベルト体５０の引出方向に沿って回動したとしても、スライダ支持体７０と共にスライダ６３が、ベルト巻取側のベルト体５０のファスナ６０（閉じ状態にある）の方向に常時、正常な状態で指向する。
この結果、スライダ６３のスライド抵抗が増大されることを抑制することができ、スライダ６３のスライド性が良好に保たれ、ファスナ６３が円滑に開かれる。 On the other hand, the slider support 70 is formed separately from the belt guide member 11 and is disposed at a portion located on the belt winding side of the insertion hole 14 of the belt guide member 11.
For this reason, even if the belt guide member 11 rotates about the attachment shaft 19 along the pulling direction of the belt body 50, the slider 63 together with the slider support body 70 moves the fastener 60 ( Always in the normal direction (in the closed state).
As a result, an increase in the slide resistance of the slider 63 can be suppressed, the sliding property of the slider 63 is kept good, and the fastener 63 is smoothly opened.

また、この実施例１において、スライダ支持体７０は、ベルト案内部材１１と共通の取付軸１９によって車体側部材に取り付けられる。このため、スライダ支持体７０専用の取付部材が不要となり、この分だけ部品点数や組付工数を削減することができる。   In the first embodiment, the slider support body 70 is attached to the vehicle body side member by the attachment shaft 19 common to the belt guide member 11. For this reason, the attachment member only for the slider support body 70 becomes unnecessary, and can reduce the number of parts and an assembly man-hour by this.

なお、この発明は前記実施例１に限定するものではなく、この発明の要旨を逸脱しない範囲内において、種々の形態で実施することができる。
例えば、前記実施例１において、スライダ支持体７０は、ベルト案内部材１１と共通の取付軸１９によって、車体側部材に取り付けられる場合を例示したが、スライダ支持体７０は、ベルト案内部材１１とは別の取付部材によって車体側部材に取り付けられてもよい。
また、スライダ支持体７０は、ベルト案内部材１１に対し相対回動可能に取り付けることも可能である。 In addition, this invention is not limited to the said Example 1, In the range which does not deviate from the summary of this invention, it can implement with a various form.
For example, in the first embodiment, the case where the slider support body 70 is attached to the vehicle body side member by the common mounting shaft 19 with the belt guide member 11 is illustrated, but the slider support body 70 is the same as the belt guide member 11. You may attach to a vehicle body side member with another attachment member.
Further, the slider support 70 can be attached to the belt guide member 11 so as to be rotatable relative to the belt guide member 11.
