Description

本発明は、シートバックにおけるシートバックパットをカバーリングするシートカバーの端末係止構造に関する。   The present invention relates to a seat cover terminal locking structure for covering a seat back pad in a seat back.

従来より、図２に示すように、自動車の座席は、シートクッション１とシートバック２とから構成されている。このシートバック２について詳述すると、シートバック２は、シートフレーム（図示しない）と、このシートフレームに包着状に取り付けられるシートバックパッド（図示しない）と、このシートバックパッドをカバーリングするシートカバー２３と、シートフレームの後面側に取り付けられ合成樹脂からなるバックボード２４とによって構成されている。この構成において、シートカバー２３の端末は、バックボード２４に掛け止めされている。この掛け止めについて詳述すると、図３、４に示すように、シートカバー２３の端末には、端末の縁に沿って適宜の間隔を介して剛性を有する樹脂からなる短冊形状のプレート部材２５が結着（例えば、縫い付け）されている。また、バックボード２４の周縁には、バックボード２４と一体となるように成形された取付溝２４ａが形成されており、この取付溝２４ａの開口部近傍の内面のうち、シートカバー２３にて巻き込まれる側の側面（バックボード２４に対して外側に位置する外側壁２４ｂ）には、適宜の間隔を介して内向きに向けて突出する係止爪２４ｃが形成されている。そして、取付溝２４ａの内部にプレート部材２５を挿入させていくと、プレート部材２５において、プレート部材２５を挿入させ始めた側の端部と反対側の端部（図４において、プレート部材２５の右端部）が係止爪２４ｃに掛け止めされる。このようにして、シートカバー２３の端末は、バックボード２４に掛け止めされている。   Conventionally, as shown in FIG. 2, an automobile seat is composed of a seat cushion 1 and a seat back 2. The seat back 2 will be described in detail. The seat back 2 includes a seat frame (not shown), a seat back pad (not shown) attached to the seat frame in a covering manner, and a seat covering the seat back pad. The cover 23 and a backboard 24 made of synthetic resin are attached to the rear side of the seat frame. In this configuration, the terminal of the seat cover 23 is hooked on the back board 24. More specifically, as shown in FIGS. 3 and 4, the end of the seat cover 23 has a strip-shaped plate member 25 made of a resin having rigidity through an appropriate interval along the edge of the end. It is bound (for example, sewn). A mounting groove 24a formed so as to be integrated with the backboard 24 is formed at the periphery of the backboard 24. Of the inner surface in the vicinity of the opening of the mounting groove 24a, the seat cover 23 winds up. A locking claw 24c is formed on the side surface (the outer wall 24b positioned on the outer side with respect to the backboard 24). When the plate member 25 is inserted into the mounting groove 24a, the end of the plate member 25 opposite to the end on which the plate member 25 is started to be inserted (in FIG. The right end) is hooked on the locking claw 24c. In this way, the terminal of the seat cover 23 is hooked on the back board 24.

しかしながら、上述した掛け止め構造では、取付溝の内部にプレート部材を挿入させるとき、作業者は自身の指でプレート部材を押し込んでいかなければならなかった。そのため、例えば、図４に示すように、取付溝の幅が狭いため取付溝の内部に指の先端しか入れ込むことができない場合、プレート部材は短冊形状であるため、作業者にとってプレート部材は押し込み難いものとなっており、押し込みの作業性が悪いという問題が発生していた。また、プレート部材の押し込みが完了してプレート部材を掛け止めたとき、係止爪の凹凸がシートカバーの表面に現れてしまうため（所謂、ハイライトが現れてしまうため）、掛け止め状態の見栄えが悪くなるという問題が発生していた。そこで、これらの問題を解決するためのシートカバーの端末係止構造が求められていた。   However, in the above-described latching structure, when inserting the plate member into the mounting groove, the operator has to push the plate member with his / her finger. Therefore, for example, as shown in FIG. 4, when the width of the mounting groove is narrow so that only the tip of the finger can be inserted into the mounting groove, the plate member has a strip shape. There was a problem that the push-in workability was poor. In addition, when the plate member is pushed in and the plate member is latched, irregularities of the latching claw appear on the surface of the seat cover (so-called highlights appear), so that the latched state looks good Had a problem of getting worse. Therefore, a seat cover terminal locking structure for solving these problems has been desired.

本発明は、これらの課題を解決しようとするもので、その目的は、バックボードの周縁に形成された取付溝の内面に形成された係止爪に対してシートカバーの端末に結着されたプレート部材を挿入させて掛け止める場合であっても、掛け止めの作業性、およびその掛け止め状態の見栄えを向上させることができるシートカバーの端末係止構造を提供することである。   The present invention is intended to solve these problems, and its purpose is to bind to the end of the seat cover with respect to the locking claw formed on the inner surface of the mounting groove formed on the periphery of the backboard. Even when a plate member is inserted and latched, it is an object to provide a terminal cover locking structure of a seat cover that can improve the workability of the latch and the appearance of the latched state.

本発明は、上記の目的を達成するためのものであって、以下のように構成されている。
請求項１に記載の発明は、シートパッドを覆うようにシートカバーを取り付けた後、その端末をシートフレームまたはフレーム側の設置部材（例えば、バックボード）に設けられた取付溝に係止したシートカバーの端末係止構造であって、前記取付溝の開口部近傍の内壁面のうち、シートカバーにて巻き込まれる側の側面には、係止爪が突出形成され、前記シートカバーの端末には前記取付溝に挿入係止可能なプレート部材が一体的に縫着されており、前記プレート部材の端部のうち、係止状態にて取付溝の開口部側に位置する端部には、前記係止爪が形成された壁面に向けて断面略Ｌ字状に伸びるフック部が設けられるとともに、係止爪を挟んで前記フック部と対向する側には、前記係止爪に掛止される引掛爪が形成されている構成である。
この構成によれば、プレート部材を挿入させるとき、取付溝の幅が狭いため取付溝の内部に指の先端しか入れ込むことができない場合であっても、作業者はプレート部材のフック部を押し込んでいけばよいため、作業者にとってプレート部材は押し込み易いものとなっており、押し込みの作業性が悪いという問題は改善されることになる。また、プレート部材の引掛爪が取付溝に形成の係止爪に掛け止めされると、プレート部材のフック部によって係止爪は覆われる格好となる。これにより、係止爪の凹凸がシートカバーの表面に現れてしまうことがないため、掛け止め状態の見栄えを向上させることができる。 The present invention is for achieving the above object, and is configured as follows.
According to the first aspect of the present invention, after the seat cover is attached so as to cover the seat pad, the terminal is engaged with an attachment groove provided in a seat frame or a frame-side installation member (for example, a backboard). The cover has a terminal locking structure, and a locking claw is formed on the side surface of the inner wall near the opening of the mounting groove so as to be wound on the seat cover. A plate member that can be inserted and locked in the mounting groove is integrally sewn, and among the ends of the plate member, the end located on the opening side of the mounting groove in the locked state A hook portion extending in a substantially L-shaped cross section is provided toward the wall surface on which the locking claw is formed, and is hooked by the locking claw on the side facing the hook portion with the locking claw interposed therebetween. It is the structure where the hooking claw is formed
According to this configuration, when the plate member is inserted, even if only the tip of the finger can be inserted into the mounting groove because the width of the mounting groove is narrow, the operator pushes in the hook portion of the plate member. Therefore, it is easy for the operator to push the plate member, and the problem of poor pushability is improved. Further, when the hooking claw of the plate member is hooked on the locking claw formed in the mounting groove, the locking claw is covered with the hook portion of the plate member. Thereby, since the unevenness | corrugation of a latching claw does not appear on the surface of a seat cover, the appearance of a latching state can be improved.

また、請求項２に記載の発明は、請求項１に記載のシートカバーの端末係止構造であって、前記フック部には、前記断面略Ｌ字状の反り返り方向と反対方向に向けて突出する隙詰部が形成された構成である。
この構成によれば、隙詰部によって、取付溝の内部が充填される格好となる。これにより、シートカバーの端末をバックボードに掛け止めたとき、シートカバーとバックボードとの間で一体感を出せるようになる。 In addition, the invention according to claim 2 is the seat cover terminal locking structure according to claim 1, wherein the hook portion protrudes in a direction opposite to the warping direction of the substantially L-shaped cross section. It is the structure in which the gap part to be formed was formed.
According to this configuration, the interior of the mounting groove is filled with the gap portion. Thereby, when the terminal of the seat cover is hooked on the back board, a sense of unity can be provided between the seat cover and the back board.

以下、本発明を実施するための最良の形態を、図１を用いて説明する。
図１は、本発明におけるシートカバーの端末係止構造を示す断面図である。なお、以下の実施例で説明するシートカバー２３の掛け止め構造は、従来技術で説明したシートカバー２３の掛け止め構造と比較すると、シートカバー２３の端末に結着されたプレート部材２６（従来技術では、プレート部材２５）の形状が相違している。その他の構成については、実施例と従来技術とは同一構成であるため、図面において同一符号を付すことで重複する説明は省略する。 Hereinafter, the best mode for carrying out the present invention will be described with reference to FIG.
FIG. 1 is a cross-sectional view illustrating a terminal cover locking structure of a seat cover according to the present invention. Note that the latching structure of the seat cover 23 described in the following embodiments is compared with the latching structure of the seat cover 23 described in the prior art, and the plate member 26 (prior art) attached to the end of the seat cover 23. Then, the shape of the plate member 25) is different. Regarding the other configurations, the embodiment and the prior art have the same configuration, so that the same reference numerals are used in the drawings to omit redundant description.

図１に示すように、この実施例のプレート部材２６は、従来技術のプレート部材２５に対して、フック部２６ａと、引掛爪２６ｂと、隙詰部２６ｃの構成を追加したものである。これらの追加構成について詳述すると、フック部２６ａは、プレート部材２６の端部のうち、係止状態にて取付溝２４ａの開口部側に位置する端部（図１において、プレート部材２６の右端部）に、係止爪２４ｃが形成された壁面に向けて断面略Ｌ字状に伸びるよう設けられている。   As shown in FIG. 1, the plate member 26 of this embodiment is obtained by adding a configuration of a hook portion 26a, a hooking claw 26b, and a gap portion 26c to the plate member 25 of the prior art. When these additional structures are described in detail, the hook portion 26a is an end portion of the end portion of the plate member 26 that is positioned on the opening side of the mounting groove 24a in the locked state (in FIG. 1, the right end of the plate member 26). Part) is provided so as to extend in a substantially L-shaped cross section toward the wall surface on which the locking claw 24c is formed.

引掛爪２６ｂは、プレート部材２６において、上述した係止爪２４ｃを挟んでフック部２６ａと対向する側に、係止爪２４ｃに掛止されるよう形成されている。   The hooking claw 26b is formed on the plate member 26 so as to be hooked by the locking claw 24c on the side facing the hook portion 26a across the locking claw 24c described above.

隙詰部２６ｃは、フック部２６ａにおいて、上述した断面略Ｌ字状の反り返り方向と反対方向に向けて突出するように形成されている。なお、これらフック部２６ａと、引掛爪２６ｂと、隙詰部２６ｃは、プレート部材２６と一体となるように剛性を有する樹脂によって成形されている。   The gap portion 26c is formed in the hook portion 26a so as to protrude in a direction opposite to the warping direction having the substantially L-shaped cross section described above. The hook portion 26 a, the hooking claw 26 b, and the gap portion 26 c are molded from a rigid resin so as to be integrated with the plate member 26.

続いて、上述した構成からなるプレート部材２６の作用を説明する。従来技術と同様に、取付溝２４ａの内部にプレート部材２６を挿入させていくと、プレート部材２６の引掛爪２６ｂは取付溝２４ａに形成の係止爪２４ｃを乗り越えて係止爪２４ｃに掛け止めされる。これにより、従来技術と同様に、シートカバー２３の端末は、バックボード２４に掛け止めされることになる。   Subsequently, the operation of the plate member 26 having the above-described configuration will be described. As in the prior art, when the plate member 26 is inserted into the mounting groove 24a, the hooking claw 26b of the plate member 26 gets over the locking claw 24c formed in the mounting groove 24a and latches to the locking claw 24c. Is done. As a result, the terminal of the seat cover 23 is latched to the back board 24 as in the prior art.

また、プレート部材２６を挿入させるとき、従来技術で説明したように、取付溝２４ａの幅が狭いため取付溝２４ａの内部に指の先端しか入れ込むことができない場合であっても、作業者はプレート部材２６のフック部２６ａを押し込んでいけばよいため、作業者にとってプレート部材２６は押し込み易いものとなっており、押し込みの作業性が悪いという問題は改善されることになる。   Further, when the plate member 26 is inserted, as described in the prior art, even if the tip of the finger can only be inserted into the mounting groove 24a because the width of the mounting groove 24a is narrow, the operator can Since it is only necessary to push in the hook portion 26a of the plate member 26, the plate member 26 is easy to be pushed for the operator, and the problem of poor pushability is improved.

また、プレート部材２６の引掛爪２６ｂが取付溝２４ａに形成の係止爪２４ｃに掛け止めされると、プレート部材２６のフック部２６ａによって係止爪２４ｃは覆われる格好となる。これにより、従来技術で説明したように、係止爪２４ｃの凹凸がシートカバー２３の表面に現れてしまうことがないため、掛け止め状態の見栄えを向上させることができる。   Further, when the hooking claw 26b of the plate member 26 is hooked by the locking claw 24c formed in the mounting groove 24a, the hooking claw 24c of the plate member 26 is covered with the hooking claw 24c. Thereby, as explained in the prior art, the unevenness of the locking claw 24c does not appear on the surface of the seat cover 23, so that the appearance of the latched state can be improved.

また、この掛け止め状態において、隙詰部２６ｃによって、取付溝２４ａの内部が充填される格好となる。これにより、シートカバー２３の端末をバックボード２４に掛け止めたとき、シートカバー２３とバックボード２４との間で一体感を出せるようになる。   Further, in this latched state, the interior of the mounting groove 24a is filled by the gap portion 26c. Thereby, when the terminal of the seat cover 23 is hooked on the back board 24, a sense of unity can be provided between the seat cover 23 and the back board 24.

上述した内容は、あくまでも本発明の一実施の形態に関するものであって、本発明が上記内容に限定されることを意味するものではない。
実施例では、シートバック２におけるシートカバー２３の端末を係止させる場合を例に説明した。しかし、これに限定されるものでなく、シートクッション１におけるシートカバーに適用させても構わない。 The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
