Description

本発明は、自動車のドア周縁に沿って取付けられ、ボディ側に弾接してドアとボディとの間をシールするドアウェザーストリップに関する。 The present invention relates to a door weather strip that is attached along the periphery of a door of an automobile and elastically contacts the body side to seal between the door and the body.

図８及び図９に示すように、自動車のドア１の周縁に沿ってドア１とボディのドア開口縁部２の間をシールするドアウェザーストリップ１０が取付けられている。
ドアウェザーストリップ１０は、ドア１周縁に沿って直接取付けられる取付基部１１と、その取付基部１１の車内側に一体成形されドア１の閉時にはボディのドア開口縁２の車内側に弾接する中空シール部１２と、取付基部１１の車外側に一体成形され同じくドア１の閉時にはドア開口縁２の車外側に弾接するシールリップ部１３を備えている。 As shown in FIGS. 8 and 9, a door weather strip 10 is attached along the periphery of the door 1 of the automobile to seal between the door 1 and the door opening edge 2 of the body.
The door weatherstrip 10 is a hollow seal that is directly formed along the periphery of the door 1 and a hollow seal that is integrally formed on the vehicle inner side of the mounting base 11 and elastically contacts the vehicle inner side of the door opening edge 2 of the body when the door 1 is closed. And a seal lip portion 13 that is integrally formed on the vehicle exterior side of the mounting base portion 11 and that elastically contacts the vehicle exterior side of the door opening edge 2 when the door 1 is closed.

このようなドアウェザーストリップ１０では遮音性を向上させるために中空シール部１２の肉厚を、図９に示すように大きくして面密度を高くすることが考えられるが、ドア１の閉時に中空シール部１２が撓んだ際に、図１０に示すように、中空シール部１２の上面側に断面略Ｕ字形状に膨らんだ部位１２ａが生じ、その根元同士が接触するとドア閉じ性が悪くなるといった問題がある。 In such a door weather strip 10, in order to improve sound insulation, it is conceivable to increase the thickness of the hollow seal portion 12 as shown in FIG. 9 to increase the surface density. When the seal portion 12 is bent, as shown in FIG. 10, a portion 12 a swelled in a substantially U-shaped cross section is formed on the upper surface side of the hollow seal portion 12. There is a problem.

これに対して、シールリップ部１３を１枚から２枚にすることで遮音壁を増加させることも考えられる（例えば、特許文献１参照）が、２枚のシールリップ部１３が互いに接触すると同様にドア閉じ性が悪くなるため、車外側のシールリップ部をより車外側に移動させると先端がボディのドア開口縁２から車外側にはみ出して外観性が悪くなりシール性にも問題が発生し、逆に、車内側のシールリップ部をより車内側に移動させると車内側のシールリップ部が断面略Ｕ字形状に膨らんだ部位に接触してドア閉じ性が悪くなってしまう。 On the other hand, it is also conceivable to increase the sound insulation wall by changing the number of the sealing lip portions 13 from one to two (for example, see Patent Document 1), but in the same manner when the two sealing lip portions 13 contact each other. Since the door closing performance is deteriorated, if the seal lip portion on the outside of the vehicle is moved further to the outside of the vehicle, the tip protrudes from the door opening edge 2 of the body to the outside of the vehicle, the appearance is deteriorated, and a problem occurs in the sealing performance. On the contrary, if the seal lip portion on the vehicle inner side is moved further to the vehicle inner side, the seal lip portion on the vehicle inner side comes into contact with a portion swelled in a substantially U-shaped cross section, and the door closing performance is deteriorated.

また、中空シール部の上面壁の取付基部側から延びる方向をドアの進入軌跡よりも中空シール部の底面側に下げるようにすれば（例えば、特許文献２参照）、断面略Ｕ字形状に膨らんだ部位の発生を抑えることができるが、中空シール部の上面壁とボディのドア開口縁部２との間に大きな隙間ができるため、遮音性能としては不十分である。 Further, if the direction extending from the mounting base side of the upper surface wall of the hollow seal portion is lowered to the bottom surface side of the hollow seal portion with respect to the entrance locus of the door (see, for example, Patent Document 2), the section expands into a substantially U shape. The generation of the part can be suppressed, but since a large gap is formed between the upper surface wall of the hollow seal portion and the door opening edge 2 of the body, the sound insulation performance is insufficient.

なお、括弧内の記号は、図面および後述する発明を実施するための形態に記載された対応要素または対応事項を示す。 Note that symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.

本発明によれば、中空シール部の第二付け根部の位置を取付基部の車内側壁部端部側に寄った部位に配置したので、ドアの閉時にドアの周縁とボディのドア開口縁間は、取付基部と中空シール部によって大きく覆い隠され、覆われずに残った隙間は少ない領域となる。これにより、優れた遮音性効果が得られる。
そして取付基部の車内側壁部と車外側壁部の接続位置頂点から近接するボディのドア開口縁までの距離は、底壁部に対する車内側壁部と車外側壁部の接続位置頂点までの距離の１／２以下といったように、取付基部において車内側壁部と車外側壁部の接続位置は、従来のドアウェザーストリップに比べてドアの閉時にはボディのドア開口縁側に大きく寄った位置に設けられることになる。
しかも、中空シール部は第一付け根部と第二付け根部を介して車内側壁部に接続されるが、中空シール部の車内側の底面に相対向するドア周縁の面を延長した基準線に対する中空シール部の最高位置までの距離を、基準線に対する車内側壁部と車外側壁部の接続位置頂点までの距離以下にするように中空シール部の断面形状は設定されるので、ドアの閉時に中空シール部がボディのドア開口縁に弾接する際に、従来例で示したような断面略Ｕ字形状に膨らんだ部位が中空シール部に発生したり、中空シール部が第一シールリップ部に干渉することによってドア閉じ性を特に悪化させることもない。 According to the present invention, since the position of the second root portion of the hollow seal portion is arranged at a position close to the end portion of the inner wall portion of the mounting base portion, when the door is closed, between the door periphery and the door opening edge of the body The gap that remains largely uncovered by the mounting base and the hollow seal portion is small. Thereby, the outstanding sound-insulating effect is acquired.
And the distance from the connection position vertex of the vehicle interior side wall portion and the vehicle outer wall portion of the mounting base to the door opening edge of the adjacent body is 1 of the distance from the connection wall vertex of the vehicle inner wall portion and the vehicle outer wall portion to the bottom wall portion. / 2 or less, the connection position of the vehicle interior side wall and the vehicle exterior wall in the mounting base is provided closer to the door opening edge side of the body when the door is closed than in the conventional door weather strip. Become.
In addition, the hollow seal portion is connected to the vehicle interior side wall portion via the first root portion and the second root portion, but the hollow seal portion is hollow with respect to a reference line extending the surface of the door periphery facing the bottom surface on the vehicle inner side of the hollow seal portion. Since the cross-sectional shape of the hollow seal part is set so that the distance to the highest position of the seal part is less than or equal to the distance between the vehicle inner wall part and the vehicle outer wall part relative to the reference line, the hollow part is hollow when the door is closed. When the seal part elastically contacts the door opening edge of the body, a portion swelled in a substantially U-shaped cross section as shown in the conventional example occurs in the hollow seal part, or the hollow seal part interferes with the first seal lip part. By doing so, the door closing property is not particularly deteriorated.

また、本発明によれば、中空シール部の第二付け根部の位置を、取付基部の車内側壁部と車外側壁部の接続位置にしたので、ドアの閉時にドアの周縁とボディのドア開口縁間は、取付基部と中空シール部によって最も大きく覆い隠され、覆われずに残った隙間は極めて少ない領域となり、その分遮音性効果は一層大きいものとなる。 Further, according to the present invention, since the position of the second base portion of the hollow seal portion is the connection position between the vehicle interior side wall portion and the vehicle exterior wall portion of the mounting base portion, when the door is closed, the peripheral edge of the door and the door opening of the body are opened. The gap between the edges is covered most by the mounting base and the hollow seal portion, and the gap remaining without being covered is an extremely small region, and the sound insulation effect is further increased accordingly.

また、本発明によれば、中空シール部のボディのドア開口縁側の面を第二付け根部から車内側に向けて真っ直ぐ延びる平担面にしたので中空シール部をボディのドア開口縁に対して密に弾接させることができる。 Further, according to the present invention, since the surface of the hollow seal portion on the door opening edge side of the body is a flat bearing surface extending straight from the second root portion toward the inside of the vehicle, the hollow seal portion is made to the door opening edge of the body. It can be in close contact.

また、本発明によれば、シールリップ部は、取付基部の車外側に互いに離間した状態で一体成形された第一シールリップ部及び第二シールリップ部からなるといったように、二枚のシールリップ部からなるので、一枚のものと比較して遮音効果は増加する。
そして、ボディのドア開口縁に弾接する時、第一シールリップ部及び第二シールリップ部は互いに干渉しないように配置されているのでドア閉じ性を悪化させることが防止される。 Further, according to the present invention, the seal lip portion includes the first seal lip portion and the second seal lip portion that are integrally formed in a state of being separated from each other on the vehicle outer side of the mounting base portion. Since it consists of parts, the sound insulation effect is increased compared to a single sheet.
Then, when the first seal lip portion and the second seal lip portion are arranged so as not to interfere with each other when elastically contacting the door opening edge of the body, it is possible to prevent the door closing performance from being deteriorated.

また、本発明によれば、取付基部の断面形状を略三角形状にするとともに、第一シールリップ部を車内側壁部と車外側壁部の接続位置から延設し、第二シールリップ部を車外側壁部の略中間位置から延設したので、両シールリップ部同士が接触することを防止しつつ両シールリップ部を安定して取付基部で支持することができる。
しかも、両シールリップ部は、取付基部の底壁部の車外側から車内側壁部端部に向けて車内側に斜めに延びる車外側壁部から延設されているため、底壁部に略平行に車内外方向に延びる部位に両シールリップ部を離間させた状態で設けた場合と比較して第一シールリップ部に対して第二シールリップ部をより車内側に配置させることができ、第二シールリップ部がドアから車外側にはみ出す危険性を回避することができる。 Further, according to the present invention, the mounting base portion has a substantially triangular cross-sectional shape, the first seal lip portion extends from the connection position of the vehicle inner wall portion and the vehicle outer wall portion, and the second seal lip portion is connected to the vehicle. Since it extended from the substantially middle position of the outer wall part, both seal lip parts can be stably supported by the mounting base while preventing the seal lip parts from contacting each other.
In addition, since both the seal lip portions are extended from the vehicle outer side wall portion that extends obliquely toward the vehicle inner side from the vehicle outer side of the bottom wall portion of the mounting base portion toward the vehicle inner side wall portion end portion, the seal lip portions are substantially parallel to the bottom wall portion. The second seal lip portion can be disposed more inside the vehicle than the first seal lip portion compared to the case where the seal lip portions are provided in a state of being separated from each other at a portion extending in the vehicle interior / exterior direction. The risk of the two seal lip portions protruding from the door to the outside of the vehicle can be avoided.

図１，図２及び図８を参照して、本発明の実施形態に係るドアウェザーストリップについて説明する。なお、従来例と同一部分は同一符号を付した。図１は本発明の実施形態に係るドアウェザーストリップ２０がボディのドア開口縁２に弾接する前の状態を示し、図２はボディのドア開口縁２に弾接した状態を示している。 A door weather strip according to an embodiment of the present invention will be described with reference to FIGS. In addition, the same code | symbol was attached | subjected to the same part as the prior art example. FIG. 1 shows a state before a door weather strip 20 according to an embodiment of the present invention elastically contacts the door opening edge 2 of the body, and FIG. 2 shows a state where the door weatherstrip 20 elastically contacts the door opening edge 2 of the body.

このドアウェザーストリップ２０は、図１及び図８に示すように、自動車のドア１周縁に沿って取付けられる取付基部２１と、その取付基部２１の車内側に一体成形されドア１閉時にはボディのルーフ側のドア開口縁２の車内側に弾接する中空シール部２２と、取付基部２１の車外側に一体成形されドア１閉時には、中空シール部２２とともにドア開口縁２の車外側に弾接する二つのシールリップ部（第一シールリップ部２３と第二シールリップ部２４）を備えている。 As shown in FIGS. 1 and 8, the door weather strip 20 is integrally formed on the inner side of the mounting base 21 along the periphery of the door 1 of the automobile, and the roof of the body when the door 1 is closed. A hollow seal portion 22 that elastically contacts the vehicle interior of the door opening edge 2 on the side, and two that are integrally molded on the vehicle exterior side of the mounting base 21 and elastically contact the vehicle exterior of the door opening edge 2 together with the hollow seal portion 22 when the door 1 is closed. Seal lip portions (first seal lip portion 23 and second seal lip portion 24) are provided.

取付基部２１は、底壁部２１ａ，車内側壁部２１ｂ及び車外側壁部２１ｃがそれぞれ接続された断面形状を略三角形状にしたもので断面略中央に中空部２５が形成されている。
底壁部２１ａは、ドア１周縁となるフレーム（サッシュでもよい）の水平に延びる取付面１ａに接して取付けられる板状でありその車内側端部及び車外側端部がドア１のフレームに形成された嵌合部１Ｘ，１Ｙに嵌め込まれることによって取付けられている。なお、底壁部２１ａを嵌合部１Ｘ，１Ｙに嵌め込むことにかえてクリップ（図示しない）を介してドア１周縁に固定するようにしてもよい。
車内側壁部２１ｂは、底壁部２１ａの車内側からドア１閉時のボディのドア開口縁２側に向けて車外側に斜めに延びている。
車外側壁部２１ｃは、底壁部２１ａの車外側からドア１閉時のボディのドア開口縁２側に向けて車内側に斜めに延びて車内側壁部２１ｂの端部に接続されている。 The mounting base 21 has a substantially triangular shape in cross section to which the bottom wall portion 21a, the vehicle interior side wall portion 21b, and the vehicle exterior wall portion 21c are connected, and a hollow portion 25 is formed at the approximate center of the cross section.
The bottom wall portion 21a is a plate shape that is attached in contact with a horizontally extending attachment surface 1a of a frame (may be a sash) that is a peripheral edge of the door 1, and an inner end portion and an outer end portion of the vehicle are formed on the frame of the door 1. It is attached by being fitted into the fitted portions 1X and 1Y. Note that the bottom wall portion 21a may be fixed to the periphery of the door 1 via a clip (not shown) instead of being fitted into the fitting portions 1X and 1Y.
The vehicle interior side wall 21b extends obliquely outward from the vehicle interior of the bottom wall 21a toward the vehicle door opening edge 2 when the door 1 is closed.
The vehicle outer wall 21c extends obliquely toward the vehicle inner side from the vehicle outer side of the bottom wall 21a toward the door opening edge 2 of the body when the door 1 is closed, and is connected to the end of the vehicle inner wall 21b.

そして、車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐから近接するボディのドア開口縁２までの距離Ｍは、底壁部２１ａに対する車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｔの１／２以下（ここでは略１／５にしている）になるようにしている。このとき、取付基部２１の底壁部２１ａに対する車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｔを、底壁部２１ａの幅（車内外方向の長さ）Ｗ以上にしてもよい。 And the distance M from the connection position vertex P of the vehicle interior side wall 21b and the vehicle exterior wall 21c to the door opening edge 2 of the adjacent body is the connection position of the vehicle interior wall 21b and the vehicle exterior wall 21c with respect to the bottom wall 21a. The distance T is set to be equal to or less than ½ of the distance T to the vertex P (here, approximately では). At this time, the distance T to the connection position vertex P of the vehicle interior side wall portion 21b and the vehicle exterior wall portion 21c with respect to the bottom wall portion 21a of the mounting base portion 21 is set to be equal to or greater than the width (length in the vehicle interior / external direction) W of the bottom wall portion 21a. May be.

また、取付基部２１の車外側壁部２１ｃの肉厚は底壁部２１ａ及び車内側壁部２１ｂの肉厚よりも厚く設定するとともに、車外側壁部２１ｃの底壁部２１ａ側の肉厚Ｋは車内側壁部２１ｂ端部側の肉厚Ｊよりも厚く設定して、第一シールリップ部２３と第二シールリップ部２４を安定して支持するようにしている。 Further, the thickness of the outer wall 21c of the mounting base 21 is set to be thicker than the thickness of the bottom wall 21a and the inner wall 21b, and the thickness K of the outer wall 21c on the bottom wall 21a side is The first seal lip portion 23 and the second seal lip portion 24 are stably supported by setting the thickness J to be thicker than the wall thickness J on the end side of the vehicle inner wall portion 21b.

中空シール部２２は、取付基部２１の車内側壁部２１ｂの底壁部２１ａ側に寄った部位に配置された第一付け根部２２ａと車内側壁部２１ｂの端部側に寄った部位に配置された第二付け根部２２ｂを介して車内側壁部２１ｂに接続されている。より具体的には、第一付け根部２２ａは、嵌合部１Ｘに近接した車内側壁部２１ｂに接続され、第二付け根部２２ｂは、車内側壁部２１ｂの端部、すなわち車内側壁部２１ｂと車外側壁部２１ｃの接続位置に接続されている。 The hollow seal portion 22 is disposed at the first base portion 22a disposed on the bottom wall portion 21a side of the vehicle interior side wall portion 21b of the mounting base portion 21 and the portion disposed on the end portion side of the vehicle interior side wall portion 21b. It is connected to the vehicle interior side wall portion 21b via the second root portion 22b. More specifically, the first root portion 22a is connected to the vehicle interior side wall portion 21b close to the fitting portion 1X, and the second root portion 22b is connected to the end of the vehicle interior side wall portion 21b, that is, the vehicle interior side wall portion 21b and the vehicle interior wall portion 21b. It is connected to the connection position of the outer wall 21c.

そして、中空シール部２２の車内側の底面２２ｃに相対向するドア１周縁の面１ｂを延長した線を基準線Ｌとした場合、その基準線Ｌに対する中空シール部２２の最高位置Ｑまでの距離Ｄを、基準線Ｌに対する車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｓ以下になるように中空シール部２２の断面形状を設定している。
ここでは、中空シール部２２のボディのドア開口縁２側の面２２ｄについては第二付け根部２２ｂから車内側に向けて真っ直ぐ延びる平担面とするとともに、前記基準線Ｌに平行に延びるようにしているので、車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐは中空シール部２２の最高位置Ｑとなり、基準線Ｌからその最高位置Ｑまでの距離Ｄは、基準線Ｌから車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｓと同一になる。
なお、中空シール部２２のドア１周縁２側の面２２ｅについては第一付け根部２２ａから車内側で前記基準線Ｌに交差する方向に向けて真っ直ぐ延びる平担面としている。よって、この第一付け根部２２ａから真っ直ぐ延びる平担面２２ｅの端部が、中空シール部２２の車内側の底面２２ｃの位置となる。第一付け根部２２ａから真っ直ぐ延びる平担面２２ｅの断面形状の幅（長さ）よりも、第二付け根部２２ｂから真っ直ぐ延びる平担面２２ｄの断面形状の幅（長さ）の方が長く、両平担面２２ｄ，２２ｅの端部同士を車内側に向けて膨出湾曲した曲面２２ｆで接続してなるものが中空シール部２２の断面形状を形成している。 And when the line which extended the surface 1b of the door 1 periphery which opposes the bottom face 22c inside the vehicle of the hollow seal part 22 is made into the reference line L, the distance to the highest position Q of the hollow seal part 22 with respect to the reference line L The cross-sectional shape of the hollow seal portion 22 is set so that D is equal to or less than the distance S from the reference position L to the connection position vertex P of the vehicle inner wall portion 21b and the vehicle outer wall portion 21c.
Here, the surface 22d on the door opening edge 2 side of the body of the hollow seal portion 22 is a flat bearing surface that extends straight from the second root portion 22b toward the vehicle interior side, and extends parallel to the reference line L. Therefore, the connection position apex P between the vehicle interior wall 21b and the vehicle exterior wall 21c is the highest position Q of the hollow seal portion 22, and the distance D from the reference line L to the highest position Q is the vehicle interior wall from the reference line L. It becomes the same as the distance S to the connection position vertex P of the part 21b and the vehicle outer side wall part 21c.
In addition, about the surface 22e by the side of the door 1 periphery 2 of the hollow seal part 22, it is set as the flat surface extended straight toward the direction which cross | intersects the said reference line L from the 1st root part 22a on the vehicle inside. Therefore, the end portion of the flat bearing surface 22 e that extends straight from the first root portion 22 a is the position of the bottom surface 22 c on the vehicle inner side of the hollow seal portion 22. The width (length) of the cross-sectional shape of the flat bearing surface 22d extending straight from the second root portion 22b is longer than the width (length) of the cross-sectional shape of the flat bearing surface 22e extending straight from the first root portion 22a. What forms the cross-sectional shape of the hollow seal part 22 is formed by connecting the ends of the both flat bearing surfaces 22d and 22e with a curved surface 22f that bulges and curves toward the inside of the vehicle.

第一シールリップ部２３と第二シールリップ部２４は、断面略舌形状で取付基部２１の車外側壁部２１ｃに互いに離間した状態で一体成形され、ボディのドア開口縁２に弾接する時、第一シールリップ部２３及び第二シールリップ部２４は互いに干渉しないように配置されている。すなわち、第一シールリップ部２３は、取付基部２１の車内側壁部２１ｂと車外側壁部２１ｃの接続位置から車外側に向けて延設されるとともに、第二シールリップ部２４は、車外側壁部２１ｃの略中間位置から車外側に向けて延設され、ドア１の閉時には、図２に示すように、両シールリップ部２３，２４が接触しないように第一シールリップ部２３の付け根部と第二シールリップ部２４の付け根部間には十分な空間が確保されている。また、両シールリップ部２３，２４の断面形状の長さは、第一シールリップ部２３より第二シールリップ部２４の方が長く略平行に延びていて、ドア１の閉時には両シールリップ部２３，２４は略同じ撓み量でボディのドア開口縁２に弾接するようにされている。 When the first seal lip portion 23 and the second seal lip portion 24 are integrally formed in a state of being separated from each other on the vehicle outer side wall portion 21c of the mounting base portion 21 with a substantially tongue-shaped cross section, and elastically contact the door opening edge 2 of the body, The first seal lip portion 23 and the second seal lip portion 24 are arranged so as not to interfere with each other. That is, the first seal lip portion 23 extends from the connection position of the vehicle interior side wall portion 21b and the vehicle exterior wall portion 21c of the mounting base portion 21 toward the vehicle exterior side, and the second seal lip portion 24 is formed on the vehicle exterior wall. The base portion of the first seal lip portion 23 is extended from the substantially intermediate position of the portion 21c toward the vehicle outer side so that when the door 1 is closed, the seal lip portions 23 and 24 are not in contact with each other as shown in FIG. And a sufficient space is secured between the base portions of the second seal lip portion 24. Further, the length of the cross-sectional shape of both the seal lip portions 23, 24 is longer than the first seal lip portion 23 and substantially parallel to the first seal lip portion 23. When the door 1 is closed, both seal lip portions Reference numerals 23 and 24 are adapted to elastically contact the door opening edge 2 of the body with substantially the same amount of bending.

なお、取付基部２１の車外側壁部２１ｃにおいて第二シールリップ部２４の車外側には、ドアフレームの側端に弾接するリップ２６が設けられている。 A lip 26 that elastically contacts the side edge of the door frame is provided on the vehicle outer side wall portion 21c of the attachment base portion 21 on the vehicle outer side of the second seal lip portion 24.

このように構成されたドアウェザーストリップ２０によれば、取付基部２１において車内側壁部２１ｂと車外側壁部２１ｃの接続位置は、従来のドアウェザーストリップに比べてドア１の閉時にはボディのドア開口縁２側に大きく寄った位置に設けられることになり、しかもその接続位置から中空シール部２２のボディ側の第二付け根部２２ｂが延設されているので、ドア１の閉時にドア１の周縁とボディのドア開口縁２の間は、取付基部２１と中空シール部２２で大きく覆い隠され、覆われずに残った隙間Ｚは極めて少ない領域となり、遮音性効果は大きい。
しかも、中空シール部２２のボディのドア開口縁２側の面２２ｄについては第二付け根部２２ｂから車内側に向けて真っ直ぐ延びる平担面で、第二付け根部２２ｂの位置は中空シール部２２の車内側の底面２２ｃに相対向するドア１周縁の面１ｂを延長してなる基準線Ｌに対する最高位置であるので、図２に示したように、ドア１の閉時に中空シール部２２がボディのドア開口縁２に弾接する際に、従来例で示したような断面略Ｕ字形状に膨らんだ部位が中空シール部２２に発生したり、中空シール部２２が第一シールリップ部２３に干渉することによってドア閉じ性を特に悪化させることもない。 According to the door weather strip 20 configured as described above, the connection position of the vehicle interior side wall portion 21b and the vehicle exterior wall portion 21c in the mounting base 21 is such that the door opening of the body is more closed when the door 1 is closed than in the conventional door weather strip. Since the second root portion 22b on the body side of the hollow seal portion 22 extends from the connection position, the peripheral edge of the door 1 is closed when the door 1 is closed. And the door opening edge 2 of the body are largely covered by the mounting base 21 and the hollow seal portion 22, and the gap Z remaining without being covered is an extremely small region, and the sound insulation effect is great.
Moreover, the surface 22d on the door opening edge 2 side of the body of the hollow seal portion 22 is a flat bearing surface extending straight from the second root portion 22b toward the vehicle interior, and the position of the second root portion 22b is the position of the hollow seal portion 22. Since it is the highest position with respect to a reference line L formed by extending the peripheral surface 1b of the door 1 opposite to the bottom surface 22c on the inner side of the vehicle, as shown in FIG. When elastically contacting the door opening edge 2, a portion swelled in a substantially U-shaped cross section as shown in the conventional example occurs in the hollow seal portion 22, or the hollow seal portion 22 interferes with the first seal lip portion 23. As a result, the door closing performance is not particularly deteriorated.

また、ドア１の閉時に取付基部２１の車内側において中空シール部２２がボディのドア開口縁２に弾接する際に、取付基部２１の車外側では第一シールリップ部２３及び第二シールリップ部２４といった二枚のシールリップ部がボディのドア開口縁２に弾接するので遮音性に優れるとともに、両シールリップ部２２，２３の付け根部間には十分な空間が確保されているのでドア１の閉時に両シールリップ部２３，２４同士が接触してドア閉じ性を悪化させることもない。
しかも、両シールリップ部２３，２４は、取付基部２１の底壁部２１ａの車外側から車内側壁部２１ｂの端部に向けて車内側に斜めに延びる車外側壁部２１ｃから延設されているため、底壁部２１ａに略平行に車内外方向に延びる部位に両シールリップ部２３，２４を離間させた状態で設けた場合と比較して第一シールリップ部２３に対して第二シールリップ部２４をより車内側に配置させることができ、第二シールリップ部２４がドア１から車外側にはみ出す危険性を回避することができる。 Further, when the hollow seal portion 22 elastically contacts the door opening edge 2 of the body on the vehicle inner side of the mounting base portion 21 when the door 1 is closed, the first seal lip portion 23 and the second seal lip portion are formed on the vehicle outer side of the mounting base portion 21. Since the two seal lip portions such as 24 are in elastic contact with the door opening edge 2 of the body, the sound insulation is excellent, and a sufficient space is secured between the base portions of the seal lip portions 22 and 23 so that the door 1 When the door is closed, the seal lip portions 23 and 24 do not come into contact with each other and the door closing performance is not deteriorated.
Moreover, both the seal lip portions 23 and 24 are extended from the vehicle outer side wall portion 21c that extends obliquely toward the vehicle inner side from the vehicle outer side of the bottom wall portion 21a of the mounting base 21 toward the end portion of the vehicle inner side wall portion 21b. Therefore, the second seal lip with respect to the first seal lip portion 23 is compared with the case where both the seal lip portions 23 and 24 are provided in a state of being separated from each other at a portion extending in the vehicle interior and exterior direction substantially parallel to the bottom wall portion 21a. The part 24 can be arranged more inside the vehicle, and the risk that the second seal lip part 24 protrudes from the door 1 to the outside of the vehicle can be avoided.

なお、本実施形態では、図１に示したように、中空シール部２２の車内側の底面２２ｃに相対向するドア１周縁の面１ｂを延長した線を基準線Ｌとした場合、その基準線Ｌに対する中空シール部２２の最高位置Ｑまでの距離Ｄを、基準線Ｌに対する車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｓと同一にしたが、図３に示すように、車内側壁部２１ｂに対する中空シール部２２の第一付け根部２２ａの位置を、車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐから底壁部２２ａ側に下げてもよい。
このとき、中空シール部２２のボディのドア開口縁２側の面２２ｄは第二付け根部２２ｂから車内側に向けて真っ直ぐ延びる平担面で基準線Ｌに平行に延びているので、基準線Ｌに対する中空シール部２２の最高位置Ｑまでの距離Ｄは、基準線Ｌに対する車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｓより小さくなっている。 In the present embodiment, as shown in FIG. 1, when a line extending the surface 1b of the peripheral edge of the door 1 opposite to the bottom surface 22c on the inner side of the hollow seal portion 22 is defined as a reference line L, the reference line Although the distance D to the highest position Q of the hollow seal portion 22 with respect to L is the same as the distance S to the connection position vertex P between the vehicle inner wall portion 21b and the vehicle outer wall portion 21c with respect to the reference line L, as shown in FIG. In addition, the position of the first root portion 22a of the hollow seal portion 22 relative to the vehicle interior side wall portion 21b may be lowered from the connection position vertex P between the vehicle interior side wall portion 21b and the vehicle exterior wall portion 21c to the bottom wall portion 22a side.
At this time, the surface 22d on the door opening edge 2 side of the body of the hollow seal portion 22 is a flat surface extending straight from the second root portion 22b toward the vehicle interior and extends parallel to the reference line L. The distance D to the highest position Q of the hollow seal portion 22 is smaller than the distance S to the connection position vertex P of the vehicle inner wall portion 21b and the vehicle outer wall portion 21c with respect to the reference line L.

なお、本実施形態では、中空シール部２２のボディのドア開口縁２側の面２２ｄについては第二付け根部２２ｂから車内側に向けて真っ直ぐ延びる平担面とするとともに、基準線Ｌに平行に延びるようにしたが、平行でなくても車内側に向かうに従って基準線Ｌ側に接近するようにしてもよく、その場合は車内側に向けて真っ直ぐ延びる平担面でなくてもよい。
また、逆に中空シール部２２のボディのドア開口縁２側の面２２ｄは第二付け根部２２ｂから車内側に向かうに従って基準線Ｌ側から離れるようにすることも可能ではあるが、その場合には、図４に示すように、基準線Ｌに対する中空シール部２２の最高位置Ｑまでの距離Ｄは、基準線Ｌに対する車内側壁部２１ｂと車外側壁部２１ｃの接続位置頂点Ｐまでの距離Ｓ以下になるように中空シール部２２の断面形状を設定して（図４の場合では距離Ｄ＝距離Ｓとしている）、ドア１の閉時に中空シール部２２と第一シールリップ部２３が干渉しないようにする。 In the present embodiment, the surface 22d on the door opening edge 2 side of the body of the hollow seal portion 22 is a flat bearing surface that extends straight from the second root portion 22b toward the vehicle interior, and is parallel to the reference line L. Although it extends, it may be not parallel and may approach the reference line L side toward the vehicle inner side, and in that case, it may not be a flat surface extending straight toward the vehicle inner side.
Conversely, the surface 22d on the door opening edge 2 side of the body of the hollow seal portion 22 can be separated from the reference line L side toward the vehicle inner side from the second root portion 22b, but in that case As shown in FIG. 4, the distance D from the reference line L to the highest position Q of the hollow seal portion 22 is the distance S from the reference line L to the connection position vertex P of the vehicle inner wall portion 21b and the vehicle outer wall portion 21c. The cross-sectional shape of the hollow seal portion 22 is set to be as follows (distance D = distance S in the case of FIG. 4), and the hollow seal portion 22 and the first seal lip portion 23 do not interfere when the door 1 is closed. Like that.

なお、本実施形態では、取付基部２１の断面形状を略三角形状にしたが、図５に示すように、断面形状を略矩形状にするようにしてもよい。
この場合、取付基部２１の車外側壁部２１ｃは、底壁部２１ａからボディのドア開口縁２側に向けて略直角に立設された立設部２１ｄとその立設部２１ｄの端部から車内側壁部２１ｂの端部に向けて車内側に延びる連結部２１ｅから構成される。
そして、第一シールリップ部２３は、車内側壁部２１ｂと車外側壁部２１ｃの接続位置から延設され、第二シールリップ部２４は、車外側壁部２１ｃの立設部２１ｄと連結部２１ｅの接続位置から延設されてなる。
また、取付基部２１の車外側壁部２１ｃにおける連結部２１ｅの肉厚は底壁部２１ａ及び車内側壁部２１ｂの肉厚よりも厚く設定するとともに、車外側壁部２１ｃの立設部２１ｄの肉厚Ｉは連結部２１ｅの肉厚Ｈよりも厚く設定して、第一シールリップ部２３と第二シールリップ部２４を安定して保持している。
このように取付基部２１の形状を略矩形状（その他の形状であってもよい）にしても上述した図１の場合と同様に特にドア閉じ性を悪化させることなく遮音性能を優れたものにすることができる。 In the present embodiment, the cross-sectional shape of the attachment base 21 is substantially triangular, but the cross-sectional shape may be substantially rectangular as shown in FIG.
In this case, the vehicle outer side wall portion 21c of the mounting base portion 21 includes a standing portion 21d that is erected substantially perpendicularly from the bottom wall portion 21a toward the door opening edge 2 side of the body, and an end portion of the standing portion 21d. It is comprised from the connection part 21e extended toward the vehicle inner side toward the edge part of the vehicle interior side wall part 21b.
The first seal lip portion 23 extends from the connection position between the vehicle inner wall portion 21b and the vehicle outer wall portion 21c, and the second seal lip portion 24 extends from the standing portion 21d and the connecting portion 21e of the vehicle outer wall portion 21c. It is extended from the connection position.
Further, the thickness of the connecting portion 21e in the vehicle outer wall 21c of the mounting base 21 is set to be thicker than the wall thickness of the bottom wall 21a and the vehicle inner wall 21b, and the wall of the standing portion 21d of the vehicle outer wall 21c. The thickness I is set to be thicker than the wall thickness H of the connecting portion 21e to stably hold the first seal lip portion 23 and the second seal lip portion 24.
Thus, even if the shape of the mounting base 21 is made substantially rectangular (other shapes may be used), the sound insulation performance is excellent without particularly deteriorating the door closing performance as in the case of FIG. 1 described above. can do.

また、図６及び図７に示すように、シールリップ部を第一シールリップ部２３の一枚だけにすることも可能である。この場合、第一シールリップ部２３が接続される取付基部２１の車外側壁部２１ｃの部位はドア１の閉時にボディのドア開口縁２側に近接しているので極端に第一シールリップ部２３の断面形状を大きくさせる必要はない。 Moreover, as shown in FIG.6 and FIG.7, it is also possible to make only one seal lip part the 1st seal lip part 23. FIG. In this case, the portion of the vehicle outer wall 21c of the mounting base 21 to which the first seal lip 23 is connected is close to the door opening edge 2 side of the body when the door 1 is closed. It is not necessary to increase the cross-sectional shape of 23.
