Description

本発明は車両用ドアフレームに関する。   The present invention relates to a vehicle door frame.

車内側に位置する車内側フレーム部と車外側に位置する意匠部を接続部で接続した断面形状を有するドアフレームで、接続部を挟んで、窓開口に臨む内周側にドアガラスの縁部を保持するガラスガイド部が形成され、これと反対の外周側にウェザストリップを保持するウェザストリップ保持部が形成されるタイプが知られている。周知の通りウェザストリップは、ドアを閉じた状態で車両ボディのドア開口内縁部に当接して弾性変形し、ドアと車両ボディの間を封止するものである。ドアフレームの意匠部のうちウェザストリップ保持部を構成する領域には、ウェザストリップの保持性を高めたり、ドアフレームの本体とは別体からなるウェザストリップ保持用部材との間のシール性を確保したりする目的で、車内側への突出部を形成する場合がある。例えば特許文献１のドアフレームでは、意匠部の外周側端部を折り返して車内側へ突出するビード部を形成し、このビード部を係合させてウェザストリップの保持を行なっている。   A door frame having a cross-sectional shape in which a vehicle inner frame portion located on the inner side of the vehicle and a design portion located on the outer side of the vehicle are connected by a connecting portion, and the edge portion of the door glass on the inner peripheral side facing the window opening across the connecting portion There is known a type in which a glass guide portion for holding the weather strip is formed and a weather strip holding portion for holding the weather strip is formed on the outer peripheral side opposite to the glass guide portion. As is well known, the weatherstrip is in contact with the inner edge of the door opening of the vehicle body with the door closed, and is elastically deformed to seal between the door and the vehicle body. Of the design part of the door frame, the area that constitutes the weather strip holding part enhances the holding property of the weather strip and secures the sealing property between the weather strip holding member and the door frame main body. In some cases, a projecting portion to the inside of the vehicle is formed for the purpose. For example, in the door frame of patent document 1, the outer peripheral side edge part of the design part is turned up, the bead part which protrudes to the vehicle inner side is formed, and this bead part is engaged, and the weather strip is held.

特開２００５-１４５１５７号公報JP 2005-145157 A

ドアフレームでは意匠部の幅が一定でない場合がある。例えば、上下方向に延設されるサイドサッシュ（立柱サッシュ）で、上方から下方に進むにつれて徐々に意匠部の幅を広くするタイプが知られている。ドアフレームでは一般に、ガラスガイド部に進入するドアガラスを基準として各部の形状や寸法が設定されるため、意匠部の幅が一定でないドアフレームでは、ウェザストリップ保持部の意匠部の幅が変化することになる。ところが、ウェザストリップ保持部における意匠部の幅が変化する場合に、特許文献１のドアフレームにおけるビード部のように。ウェザストリップ保持部の形状設定に関係する車内側突出部を当該意匠部の外周側端部に形成すると、ウェザストリップ保持部の要部の断面形状がドアフレームの長手方向の各部で異なってしまうという問題がある。具体的には、特許文献１のドアフレームはウェザストリップ保持用のビード部が意匠部の外周側端部の折り返し部分に設けられているため、意匠部の幅の変化に応じてドアフレームの幅方向におけるビード部の位置が変化し、一定断面のウェザストリップに対してビード部を係合させることが難しくなる。このような問題を避けるために、意匠部の幅が変化してもウェザストリップを確実に保持可能な形態のビード部を意匠部の外周側端部に形成することは、ドアフレームの製造で多用されるロール成形などでは製法上難しく、コスト高になってしまう。また、ウェザストリップ保持部を構成する意匠部の車内側突出部が、ドアフレーム本体とは別体のウェザストリップ保持用部材との間のシール性を確保するための部位である場合も、ドアフレーム本体の車内側突出部とウェザストリップ保持用部材との間の位置設定において同様の問題がある。   In the door frame, the width of the design portion may not be constant. For example, a type of side sash (standing pillar sash) extending in the vertical direction is known in which the width of the design portion is gradually increased as it progresses downward from above. In the door frame, since the shape and dimensions of each part are generally set with reference to the door glass entering the glass guide part, the width of the design part of the weather strip holding part changes in the door frame where the width of the design part is not constant. It will be. However, like the bead portion in the door frame of Patent Document 1 when the width of the design portion in the weather strip holding portion changes. If a vehicle inner side projecting part related to the shape setting of the weather strip holding part is formed at the outer peripheral side end part of the design part, the cross-sectional shape of the main part of the weather strip holding part is different in each part in the longitudinal direction of the door frame. There's a problem. Specifically, since the door frame of Patent Document 1 has a bead portion for holding a weather strip at a folded portion of the outer peripheral side end portion of the design portion, the width of the door frame is changed according to the change in the width of the design portion. The position of the bead portion in the direction changes, and it becomes difficult to engage the bead portion with a weatherstrip having a constant cross section. In order to avoid such a problem, it is often used in the manufacture of a door frame to form a bead portion that can hold the weather strip reliably even if the width of the design portion changes, at the outer peripheral side end portion of the design portion. In roll forming or the like, the manufacturing method is difficult and the cost is increased. The door frame also has a design in which the interior projecting portion of the design portion constituting the weather strip holding portion is a part for ensuring a sealing property between the weather strip holding member and the door frame main body. There is a similar problem in setting the position between the vehicle interior protrusion and the weather strip holding member.

本発明は、以上の問題点に鑑みてなされたものであり、簡単かつ安価な構成で、ウェザストリップ保持部の形状設定が容易で、かつ意匠部の幅の設定自由度が高い車両用ドアフレームを提供することを目的とする。   The present invention has been made in view of the above problems, and is a vehicle door frame that has a simple and inexpensive configuration, allows easy setting of the shape of the weather strip holding portion, and has a high degree of freedom in setting the width of the design portion. The purpose is to provide.

本発明は、車内側に位置する車内側フレーム部と、車外側に位置する意匠部と、車内側フレーム部と意匠部を接続する接続部とを有し、接続部の内周側にドアガラスの縁部を保持するガラスガイド部を有し、接続部の外周側にウェザストリップを保持するウェザストリップ保持部を有する車両用ドアフレームに関するものである。意匠部は、接続部よりもドアフレームの内周側に位置してガラスガイド部の一部を構成する内周側意匠部と、接続部よりもドアフレームの外周側に位置してウェザストリップ保持部の一部を構成する外周側意匠部とを有し、外周側意匠部は、外周側端部に車内側に折り返されたヘミング部を有し、内周側意匠部からヘミング部まで連続する意匠面の幅方向の中間位置に、車内方向に突出する突出部を有することを特徴としている。   The present invention has a vehicle inner frame portion positioned on the vehicle inner side, a design portion positioned on the vehicle outer side, and a connection portion connecting the vehicle inner frame portion and the design portion, and a door glass on the inner peripheral side of the connection portion. The present invention relates to a vehicle door frame that has a glass guide portion that holds the edge portion and a weather strip holding portion that holds the weather strip on the outer peripheral side of the connecting portion. The design part is located on the inner peripheral side of the door frame relative to the connection part, and is located on the outer peripheral side of the door frame relative to the connection part. The outer peripheral side design part has a hemming part that is folded back to the vehicle inner side at the outer peripheral side end part, and is continuous from the inner peripheral side design part to the hemming part. It has the protrusion part which protrudes in a vehicle interior direction in the intermediate position of the width direction of a design surface.

外周側意匠部の突出部からヘミング部までの幅を、ドアフレームの長手方向位置に応じて異ならせてもよい。   You may vary the width | variety from the protrusion part of an outer peripheral side design part to a hemming part according to the longitudinal direction position of a door frame.

車内側フレーム部と意匠部と接続部に亘って一体形成された主フレーム部材に突出部を形成し、この主フレーム部材に対して固定される別体のサブフレーム部材に、突出部と共にウェザストリップ保持部を構成するウェザストリップ係合部を設けるとよい。あるいは、サブフレーム部材を設けずに、突出部と共にウェザストリップ保持部を構成するウェザストリップ係合部を主フレーム部材に形成してもよい。   A protrusion is formed on the main frame member integrally formed across the vehicle inner frame portion, the design portion, and the connection portion, and the weather strip together with the protrusion is formed on a separate subframe member fixed to the main frame member. A weather strip engaging portion constituting the holding portion may be provided. Or you may form the weather strip engagement part which comprises a weather strip holding | maintenance part with a protrusion part in a main frame member, without providing a sub-frame member.

意匠部の車外側は、別体の外装部材で覆われることが好ましい。   The exterior side of the design portion is preferably covered with a separate exterior member.

以上の本発明の車両用ドアフレームによれば、外周側意匠部における意匠面の幅方向の中間位置に車内側への突出部を設けたため、この突出部を含むウェザストリップ保持部の形状設定が容易でありつつ、突出部から外周側端部（ヘミング部）までの意匠幅を自由に設定することができる。   According to the vehicle door frame of the present invention described above, since the protruding portion toward the vehicle inner side is provided at the intermediate position in the width direction of the design surface in the outer peripheral design portion, the shape of the weather strip holding portion including the protruding portion can be set. While being easy, the design width from the protruding portion to the outer peripheral side end portion (hemming portion) can be freely set.

The portion 236 serves as a terminal portion of the main frame member 20, and a portion corresponding to the connection portion 27 in each of the previous embodiments is not formed. A leg 51 of the weather strip 50 is inserted into a space surrounded by the holding claw 136 on the inner side of the vehicle, the inward protruding portion 131 on the outer side of the vehicle, and the connecting portion 26 to prevent the weather strip 50 from coming off.

以上の各実施形態のリアサイドサッシュ１７では、ウェザストリップ保持部４１を構成する外周側意匠部３０の幅方向の途中位置に、車内側へ突出形成した内方突出部３１や内方突出部１３１が設けられている。図３ないし図５の内方突出部１３１がウェザストリップ５０を直接的に保持するのに対し、図２の内方突出部３１は、ウェザストリップ５０を保持するサブフレーム部材２１の保持爪部３５の背後に突出してシール材Ｓで封止される部位であるが、主フレーム部材２０においてウェザストリップ保持部４１の要部を構成する車内側への突出部位であるという点で共通する。そして、リアサイドサッシュ１７において内方突出部３１や内方突出部１３１からヘミング部３２までの外周側の意匠幅を変化させても、ウェザストリップの保持性能に影響が及ばない。図１に示すように、リアサイドサッシュ１７は、アッパサッシュ１５に接合される上端からドアパネル１１に支持される下端側に進むにつれて徐々に意匠部２８の幅を広くしているが、外周側意匠部３０のうち内方突出部３１や内方突出部１３１よりも外周側の領域の幅を変化させることで、一様断面をなすウェザストリップ保持部４１の要部によってウェザストリップの確実な保持を行いつつ、意匠幅の変化に容易に対応させることができる。具体的には、外周側意匠部３０の外周側の端部を必要な長さで切断してヘミング部３２を形成するだけでよく、複雑な形状加工を要さない。また、内方突出部３１やや内方突出部１３１は、平板状の意匠部２８の途中を車内側へ山形に曲げただけのシンプルな形状であるため、製造が容易で製造コストを抑えることができる。   In the rear side sash 17 of each of the embodiments described above, the inwardly protruding portion 31 and the inwardly protruding portion 131 that are formed to protrude toward the vehicle inner side are located in the middle of the outer peripheral side design portion 30 constituting the weather strip holding portion 41 in the width direction. Is provided. 3 to 5 directly holds the weather strip 50, the inward protrusion 31 in FIG. 2 holds the holding claw portion 35 of the subframe member 21 that holds the weather strip 50. However, it is common in that it is a projecting portion to the vehicle inner side that constitutes a main part of the weather strip holding portion 41 in the main frame member 20. Even if the design width on the outer peripheral side from the inward protruding portion 31 or the inner protruding portion 131 to the hemming portion 32 in the rear side sash 17 is changed, the weather strip holding performance is not affected. As shown in FIG. 1, the rear side sash 17 gradually increases the width of the design portion 28 as it proceeds from the upper end joined to the upper sash 15 to the lower end side supported by the door panel 11. By changing the width of the region on the outer peripheral side of the inner projecting portion 31 and the inner projecting portion 131 among the inner projecting portion 30, the weather strip is reliably held by the main part of the weather strip holding portion 41 having a uniform cross section. However, it is possible to easily cope with changes in the design width. Specifically, it is only necessary to form the hemming portion 32 by cutting the end portion on the outer peripheral side of the outer peripheral design portion 30 with a necessary length, and complicated shape processing is not required. Moreover, since the inward protrusion part 31 and the slightly inward protrusion part 131 are the simple shape which only bent the middle of the flat design part 28 to the vehicle inner side, it is easy to manufacture and suppresses manufacturing cost. it can.
