Description

本発明は自動車、とりわけ、スライドドア型車におけるシートベルトアンカ取付構造に関する。   The present invention relates to a seat belt anchor mounting structure in an automobile, in particular, a sliding door type car.

従来のスライドドア型車のシートベルトアンカ取付構造としては、例えば特許文献１に示すように、スライドドアの閉扉時に該スライドドアのガイドローラを収用する戸袋部をサイドシル自体で構成し、このサイドシルの戸袋部分に立設したピラーの前側壁に、シートベルトのラップベルト端末のアンカブラケットをボルト・ナット締結して固定するようにしたものが知られている。   As a conventional seat belt anchor mounting structure of a sliding door type vehicle, for example, as shown in Patent Document 1, a door sill portion that uses a guide roller of the sliding door when the sliding door is closed is composed of a side sill itself. 2. Description of the Related Art An anchor bracket of a seat belt lap belt terminal is fastened with bolts and nuts to a front side wall of a pillar erected on a door pocket portion.

一方、前記アンカブラケットを締結固定するピラーの下端部内には、通常、シートベルトリトラクタを格納配置するようにしており、このシートベルトリトラクタをピラー内に配設するために、該ピラーの下端部内側壁にはリトラクタ挿入・配設用の開口部が形成され、この開口部の下縁部分にシートベルトリトラクタを取付けるリトラクタブラケットを固設するようにしていることから、前述のアンカブラケットをこのリトラクタブラケットと共に、該開口部の下縁部分に共締め固定するようにしている（特許文献２参照）。
特開平１０−１６６９９７号公報（第２〜３頁、第２図） 特開平１０−２７８７３５号公報（第２頁、第１図） On the other hand, in the lower end portion of the pillar that fastens and fixes the anchor bracket, a seat belt retractor is usually housed and disposed, and in order to dispose the seat belt retractor in the pillar, the inner side of the lower end portion of the pillar is arranged. An opening for inserting and arranging the retractor is formed in the wall, and a retractor bracket for attaching the seat belt retractor is fixed to the lower edge portion of the opening. Therefore, the above-described anchor bracket is attached to the retractor bracket. At the same time, it is fixed together with the lower edge portion of the opening (see Patent Document 2).
Japanese Patent Laid-Open No. 10-166997 (pages 2 and 3, FIG. 2) Japanese Patent Laid-Open No. 10-278735 (2nd page, FIG. 1)

しかしながら、特許文献１のように、アンカブラケットをピラー下端部の前側壁に締結固定したものでは、スライドドアを開扉した際にアンカブラケットが外側から見えるため外観を損なってしまうのみならず、ドア開口部の前後方向下側にこのアンカブラケットおよびラップベルトの下端部が存在するため、乗降の際にこれらアンカブラケット、ラップベルトが邪魔になってしまうことは否めない。   However, as disclosed in Patent Document 1, in the case where the anchor bracket is fastened and fixed to the front side wall of the lower end portion of the pillar, when the slide door is opened, the anchor bracket can be seen from the outside, so that not only the appearance is impaired, but also the door Since the anchor bracket and the lower end portion of the lap belt are present on the lower side in the front-rear direction of the opening, it cannot be denied that the anchor bracket and the lap belt get in the way when getting on and off.

そこで、前記特許文献２のように構成した場合、シートベルトリトラクタからの入力とラップベルトからの入力とが、ピラーの開口部下縁部分に作用するため、該開口部下縁部分の板厚を大きくしたり、アンカブラケット、リトラクタブラケットの共締め固定部分にジョッグル部を形成したり、あるいは、補強部材を付設する等して、取付強度を高める必要があって、コスト的におよび重量的に不利となってしまう。   Therefore, when configured as in Patent Document 2, since the input from the seat belt retractor and the input from the lap belt act on the lower edge portion of the opening of the pillar, the plate thickness of the lower edge of the opening is increased. It is necessary to increase the mounting strength by forming a joggle part in the joint fastening part of the anchor bracket or retractor bracket, or by attaching a reinforcing member, which is disadvantageous in terms of cost and weight. End up.

そこで、本発明はシートベルトのアンカブラケットを取付ける部分を、ピラーのリトラクタブラケットを取付ける部分から分離して設定することにより、ピラーの補強を削減しつつ、アンカブラケットの取付強度を高めることができるスライドドア型車におけるシートベルトアンカ取付構造を提供するものである。   Accordingly, the present invention provides a slide that can increase the anchor bracket mounting strength while reducing pillar reinforcement by setting the seat bracket anchor bracket mounting portion separately from the pillar retractor bracket mounting portion. A seat belt anchor mounting structure for a door type vehicle is provided.

本発明のシートベルトアンカ取付構造にあっては、スライドドアを閉扉した際に、該スライドドアのガイドローラを収容する戸袋部をサイドシルと別体にボックス状に形成して、この戸袋部をシルインナに車幅方向内側に向けて突出配置してある。   In the seat belt anchor mounting structure of the present invention, when the sliding door is closed, the door pocket portion for accommodating the guide roller of the sliding door is formed in a box shape separately from the side sill. And projecting toward the inside in the vehicle width direction.

そして、このボックス状の戸袋部の上壁に、シートベルトアンカ取付部を設けて、該シートベルトアンカ取付部にシートベルトのアンカブラケットを締結固定したことを最も主要な特徴としている。   The most important feature is that a seat belt anchor mounting portion is provided on the upper wall of the box-shaped door pocket portion, and an anchor bracket of the seat belt is fastened and fixed to the seat belt anchor mounting portion.

本発明によれば、ボックス状に形成された剛体骨格構造の戸袋部の上壁にシートベルトアンカ取付部を形成して、ここにアンカブラケットを締結固定しているため、該アンカブラケットの取付強度を十分に確保することができる。   According to the present invention, since the seat belt anchor mounting portion is formed on the upper wall of the door frame portion of the rigid skeleton structure formed in a box shape, and the anchor bracket is fastened and fixed thereto, the mounting strength of the anchor bracket is Can be secured sufficiently.

一方、シートベルトリトラクタを取付けるリトラクタブラケットは、ピラー下端部の車室側の側壁に形成したリトラクタ挿入・配設用の開口部の下縁部分に取付けられるが、アンカブラケットは前述のようにこのリトラクタブラケット取付け部分から分離して戸袋部上壁に取付けてあるため、ピラーのリトラクタブラケット取付部分の補強を削減することができる。   On the other hand, the retractor bracket for attaching the seat belt retractor is attached to the lower edge of the opening for inserting and arranging the retractor formed on the side wall on the passenger compartment side at the lower end of the pillar. Since it is separated from the bracket mounting portion and attached to the upper wall of the door pocket, reinforcement of the pillar retractor bracket mounting portion of the pillar can be reduced.
