Description

本発明は、自動車ドア下部のシール構造に関するものである。  The present invention relates to a seal structure for a lower part of an automobile door.

従来は自動車ドア下部には、泥やロードノイズが室内に侵入するのを防止するために、一般にウエザーストリップの他にパーティングシールが設けられている。即ち図３乃至図５に示す如く、ドアパネル１の室内側下端部の水平壁部２に、中空状ウエザーストリップ５が設けられ、また垂直壁部３に二股状のリップ６ｃを有する断面Ｙ字状のパーティングシール６が、その取付基部６ａをクリップ７により複数箇所間隔をあけて固定されている。  Conventionally, a parting seal is generally provided in addition to the weather strip in order to prevent mud and road noise from entering the room at the lower part of the automobile door. That is, as shown in FIGS. 3 to 5, a hollow weather strip 5 is provided on the horizontal wall 2 at the lower end on the indoor side of the door panel 1, and a Y-shaped cross section having a bifurcated lip 6 c on the vertical wall 3. The parting seal 6 is fixed to the attachment base 6a with a clip 7 at a plurality of intervals.

ところが、前記パーティングシール６を取付けるクリップ７の位置と、ボディパネルＰ又はガーニッシュＧとのシール位置との距離（ｄ）が大きく離れている場合、パーティングシール６は取付基部６ａがクリップ７で間隔をあけて固定されているため、ドア閉時にパーティングシール６のリップ６ｃがボディパネルＰ又はガーニッシュＧに当たって変形し、更には図５に一点鎖線で示す如く、取付基部６ａのクリップ７の非固定部分ＮＣが引っ張られてドアパネルＰの取付け面から浮き上がったり時には転びが発生した。また、そのためドアパネルＰとの密着性が無くなりシール性が低下するという問題があった。
その対策として、図６に示す如くパーティングシール６を押えるように中空状ウエザーストリップ５を密接させて取付けるようにした場合には、これらのドアへの取付けを、先にパーティングシール６を次にウエザーストリップ５を取付ける必要があり、その分取付け順序が制約されて組付けに支障を生じるという不具合があった。
そこで、本発明はかかる従来の課題に鑑みて、クリップ７で固定されたパーティングシール６のドア閉時に生じる浮き上がり防止を図ると共に、この防止のためパーティングシール６にウエザーストリップ５を密接させて取付ける場合の取付け順序が制約されるのを解消するように構成された自動車ドア下部のシール構造を提供することを目的とする。However, when the distance (d) between the position of the clip 7 for attaching the parting seal 6 and the seal position with the body panel P or garnish G is greatly separated, the mounting base 6a of the parting seal 6 is the clip 7. Since the lip 6c of the parting seal 6 hits the body panel P or the garnish G when the door is closed, the lip 6c of the parting seal 6 is deformed. Further, as shown by a one-dot chain line in FIG. The fixed part NC was pulled up and floated from the mounting surface of the door panel P, and sometimes it fell. In addition, there is a problem that the adhesiveness with the door panel P is lost and the sealing performance is lowered.
As a countermeasure, when the hollow weather strip 5 is attached so as to hold the parting seal 6 as shown in FIG. 6, the parting seal 6 is attached to the door first. There is a problem that the weather strip 5 needs to be attached to the door, and the attachment order is restricted accordingly, and the assembly is hindered.
Therefore, in view of the conventional problems, the present invention aims to prevent the parting seal 6 fixed by the clip 7 from being lifted when the door is closed, and to prevent this, the weather strip 5 is brought into close contact with the parting seal 6. It is an object of the present invention to provide a seal structure for a lower part of an automobile door which is configured so as to eliminate the restriction of the order of attachment when attaching.

課題を解決しようとする手段Means to solve the problem

かかる目的を達成するために本発明の構成は、図１に示すように、ドアパネル１の室内側下端部に、水平壁部２とその車外側に連接位置する垂直壁部３とからなる取付段部４を形成し、前記水平壁部２に中空状ウエザーストリップ５を、前記垂直壁部３にリップ６ｃを有するパーティングシール６を取付けて成る自動車ドア下部のシール構造において、前記中空状ウエザーストリップ５の中空部を構成する前記垂直壁部３側の面である前記中空状ウエザーストリップ５の背面５ｂとパーティングシール６の取付け面６ｂとの間隔（ａ）が、パーティングシール６の取付基部６ａの肉厚（ｂ）よりも幾分大きくなる如く配設し、かつパーティングシール６の取付基部６ａの上端Ｔを中空状ウエザーストリップ５の下端Ｂに対して所定の間隔（ｃ）上側にする如く配設したものであり、
また、前記間隔（ａ）と肉厚（ｂ）との寸法差（ａ−ｂ）が、１〜３ｍｍであり、
また、パーティングシール６の取付基部６ａの上端Ｔと、中空状ウエザーストリップ５の下端Ｂとの垂直方向の間隔（ｃ）が１〜３ｍｍである。 In order to achieve such an object, as shown in FIG. 1, the configuration of the present invention is a mounting step comprising a horizontal wall 2 and a vertical wall 3 connected to the vehicle outer side at the lower end on the indoor side of the door panel 1. In the sealing structure of the lower part of an automobile door, in which a hollow weather strip 5 is attached to the horizontal wall portion 2 and a parting seal 6 having a lip 6c is attached to the vertical wall portion 3, the hollow weather strip is formed. The space (a) between the back surface 5b of the hollow weather strip 5 and the mounting surface 6b of the parting seal 6 which is the surface of the vertical wall 3 constituting the hollow portion 5 is the mounting base of the parting seal 6 arranged as becomes somewhat larger than the thickness of 6a (b), and a predetermined distance from the lower end B of the hollow weather strip 5 a top end T of the mounting base 6a of parting seal 6 (c Is obtained by provided as to the upper side,
The dimensional difference (ab) between the gap (a) and the wall thickness (b) is 1 to 3 mm .
Further, the vertical interval (c) between the upper end T of the attachment base 6a of the parting seal 6 and the lower end B of the hollow weather strip 5 is 1 to 3 mm.

発明の効果The invention's effect

本発明の自動車ドア下部のシール構造は、ドアパネル１の室内側下端部に形成された取付段部４の水平壁部２に設けたウエザーストリップ５の背面５ｂと、垂直壁部３に設けたパーティングシール６の取付け面６ｂとの間隔（ａ）が、パーティングシール６の取付基部６ａの肉厚（ｂ）よりも幾分大きくなる如く配設し、かつパーティングシール６の取付基部６ａの上端Ｔを中空状ウエザーストリップ５の下端Ｂに対して所定の間隔（ｃ）上側にする如く配設したものであるから、ウエザーストリップ５とパーティングシール６の組み付け順序がどちらを先にしてもよくなり、従来の取付け順序が制約されて組付けに支障を生じるという不具合が解消される。
また、パーティングシール６の取付基部６ａの上端Ｔと、中空状ウエザーストリップ５の下端Ｂとの垂直方向の間隔（ｃ）を１〜３ｍｍとすることで、ドア閉時にパーティングシール６の二股状のリップ６ｃがボディパネルＰ等に当たり変形して取付基部６ａのクリップ７の非取付け部分ＮＣが、ドアパネルＰ取付け面から浮き上がったり転びが発生するのを防止できるという特長がある。 The sealing structure of the lower part of the automobile door according to the present invention includes a rear surface 5b of a weather strip 5 provided on the horizontal wall 2 of the mounting step 4 formed at the lower end on the indoor side of the door panel 1, and a party provided on the vertical wall 3. The spacing (a) between the mounting seal 6 and the mounting surface 6b is slightly larger than the wall thickness (b) of the mounting base 6a of the parting seal 6 , and the mounting base 6a of the parting seal 6 Since the upper end T is disposed so as to be above the lower end B of the hollow weather strip 5 by a predetermined distance (c) , the assembly order of the weather strip 5 and the parting seal 6 is the first. As a result, the conventional mounting order is restricted, and the problem of hindering assembly is solved.
Further, by setting the vertical interval (c) between the upper end T of the mounting base 6a of the parting seal 6 and the lower end B of the hollow weather strip 5 to 1 to 3 mm, the fork of the parting seal 6 is closed when the door is closed. It is possible to prevent the non-attached portion NC of the clip 7 of the attachment base portion 6a from being lifted from the door panel P attachment surface or rolling.

以下、本発明の実施例を図に基づいて詳細に説明する。図３及び図１に示す如く、自動車ドアＤの下部には、ドアパネル１の室内側下端部に、水平壁部２とその車外側に連接位置する垂直壁部３とからなる取付段部４が形成されている。前記水平壁部２には中空状ウエザーストリップ５がその取付基部５ａで取付けられ、また前記垂直壁部３には二股状のリップ６ｃを有するパーティングシール６がその取付基部６ａをクリップ７により複数箇所間隔をあけて固定されている。
前記中空状ウエザーストリップ５とパーティングシール６の取付け位置関係において、中空状ウエザーストリップ５の背面５ｂとパーティングシール６の取付け面６ｂとの間隔（ａ）が、パーティングシール６の取付基部６ａの肉厚（ｂ）よりも幾分大きくなるように配設され、またパーティングシール６の取付基部６ａの上端Ｔと中空状ウエザーストリップ５の下端Ｂとが所定の間隔（ｃ）即ちｃ＞０であるように配設されている。
られている。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 3 and 1, at the lower part of the automobile door D, there is a mounting step 4 comprising a horizontal wall 2 and a vertical wall 3 connected to the outside of the vehicle at the lower end on the indoor side of the door panel 1. Is formed. A hollow weather strip 5 is attached to the horizontal wall 2 by an attachment base 5 a, and a parting seal 6 having a bifurcated lip 6 c is attached to the vertical wall 3 by a clip 7. Fixed at intervals.
In the mounting position relationship between the hollow weather strip 5 and the parting seal 6, the distance (a) between the back surface 5 b of the hollow weather strip 5 and the mounting surface 6 b of the parting seal 6 is the mounting base 6 a of the parting seal 6. The upper end T of the mounting base 6a of the parting seal 6 and the lower end B of the hollow weather strip 5 are arranged at a predetermined distance (c), that is, c>. It is arranged to be zero.
It has been.

上記の如く中空状ウエザーストリップ５とパーティングシール６とが所定の間隔（ｃ）離れて配設されるため、それらの取付けをどちらを先にしてもよく取付け順序が制約されないので組付けに支障を生じない。
また、ドアＤが開の状態では図１の如く所定の間隔（ｃ）がｃ＞０であるが、ドアＤが閉じた状態では図２に示す如く中空状ウエザーストリップ５がボディパネルＰに当たって変形し、その背面５ｂの下端がパーティングシール６の取付基部６ａの上端Ｔに押し付けられる。つまり中空状ウエザーストリップ５の背面５ｂと、パーティングシール６の取付け面６ｂとの間隔（ａ）＝パーティングシール６の取付基部６ａの肉厚（ｂ）の関係にする即ち前記間隔（ａ）＝肉厚（ｂ）とすることで、クリップ７により複数箇所間隔をあけて固定された取付基部６ａにおける図５に示すようなクリップ７間の非固定部分ＮＣが、ドア閉時にパーティングシール６の二股状のリップ６ｃがボディパネルＰ又はガーニッシュＧに当たって引っ張られドアパネルＰの取付け面から浮き上がる不具合を生じない。As described above, since the hollow weather strip 5 and the parting seal 6 are disposed at a predetermined distance (c), the mounting order is not restricted, and the mounting order is not restricted. Does not occur.
When the door D is open, the predetermined distance (c) is c> 0 as shown in FIG. 1. However, when the door D is closed, the hollow weather strip 5 hits the body panel P as shown in FIG. Then, the lower end of the back surface 5 b is pressed against the upper end T of the mounting base portion 6 a of the parting seal 6. That is, the distance (a) between the back surface 5b of the hollow weather strip 5 and the mounting surface 6b of the parting seal 6 is equal to the thickness (b) of the mounting base 6a of the parting seal 6, that is, the distance (a). = Thickness (b) allows the non-fixed portion NC between the clips 7 as shown in FIG. 5 in the mounting base portion 6a fixed with a plurality of intervals by the clip 7 to be the parting seal 6 when the door is closed. The bifurcated lip 6c is pulled against the body panel P or the garnish G, and does not cause a problem of lifting from the mounting surface of the door panel P.
