Description
本発明は、自動車のドアやトランクリッド等の開閉体又は車体のいずれか一方に取付けられたウェザストリップが開閉体を閉じたとき、該開閉体又は車体のいずれか他方のシール面に弾接してシールし、或いは前記開閉体又は車体に取付けられるウェザストリップと前記開閉体又は車体との間のシール構造において、前記開閉体又は車体の一方又は他方に段があっても該段におけるウェザストリップのシールが損なわれることがないようにしたシール構造に関する。 In the present invention, when a weather strip attached to one of an opening / closing body such as a door or a trunk of an automobile or a vehicle body closes the opening / closing body, it elastically contacts either of the sealing surfaces of the opening / closing body or the vehicle body. In the sealing structure between the weather strip that is sealed or attached to the opening / closing body or the vehicle body and the opening / closing body or the vehicle body, even if one or the other of the opening / closing body or the vehicle body has a step, the weather strip seal in the step The present invention relates to a seal structure that prevents the damage from being damaged.
ドアやトランクリッド等の開閉体又は車体のいずれか一方には通常、開閉体を閉じたとき、開閉体と車体との間をシールするためにウェザストリップが取付けられているが、ウェザストリップが弾接する車体又は開閉体のシール面には、例えばパネルを溶接したときの溶接部分による段、高剛性を必要とする箇所を厚肉に形成したときに薄肉部分との間に段が形成されることがあり、またドアフレームと該フレームに取着されるウェザストリップ保持用のリテーナ端との間に段が形成されることがある。 A weather strip is usually attached to one of the opening / closing body such as a door and a trunk lid or the vehicle body to seal the gap between the opening / closing body and the vehicle body when the opening / closing body is closed. The sealing surface of the vehicle body or the opening / closing body that comes into contact, for example, a step formed by a welded portion when the panel is welded, or a step formed between a thin portion when a portion requiring high rigidity is formed thickly A step may be formed between the door frame and the end of the weatherstrip retainer attached to the frame.
図１は、車体の段が形成される箇所を例示するもので、センターピラー１には厚肉部分の端面によって形成される段２が、またフロント側及びリヤ側のドア開口縁部３、４のヒンジ側下部コーナには、該コーナ部分を補強するため、図に示すような補強材５、６を取付けたり、高剛性の板材に乗り換えたりした場合（以下、補強材や高剛性の板材を単に補強材等という）に補強材等の両端に形成される段７が示されている。 FIG. 1 exemplifies a place where a step of a vehicle body is formed. The center pillar 1 has a step 2 formed by an end face of a thick portion, and door opening edges 3, 4 on the front side and rear side. In order to reinforce the corner portion of the hinge-side lower corner, the reinforcing members 5 and 6 as shown in the figure are attached, or when switching to a highly rigid plate material (hereinafter referred to as a reinforcing material or a highly rigid plate material). A step 7 formed at both ends of the reinforcing material or the like is shown in FIG.
前記ドア開口縁部３、４において、ドアを閉じ、ドア周りに取付けられるウェザストリップのシール部９が段２、７に当たったとき、図２に示すように、車体１０に形成される段２、７とシール部９との間に、シール部から離れる方向に向かって凹となる三角隙１１が発生し、これによりシール不足を来たし、水洩れを発生する。 At the door opening edges 3 and 4, when the door is closed and the weather strip seal 9 attached around the door hits the steps 2 and 7, as shown in FIG. 2, the step 2 formed on the vehicle body 10. , 7 and the seal portion 9, a triangular gap 11 that is concave toward the direction away from the seal portion is generated, resulting in insufficient sealing and water leakage.
この問題を解消するため、開閉体を閉じたとき、車体又は開閉体のシール面に弾接するウェザストリップのシール部の表層部を密度の低い高発泡スポンジゴム層としたウェザストリップが開示されている（特許文献１）。 In order to solve this problem, a weather strip is disclosed in which a surface layer portion of a weather strip seal portion that elastically contacts the seal surface of the vehicle body or the open / close body when the open / close body is closed has a low-density high-foam sponge rubber layer. (Patent Document 1).
段でのシール不足は、ウェザストリップが開閉体又は車体のシール面に形成される段に弾接する場合に限らず、ウェザストリップが取付けられる開閉体又は車体に段が形成される場合において、例えばドアフレームに取着されるウェザストリップ保持用のリテーナ端により形成される段においても同様に生ずる。この問題に対処するため、段に当たる箇所のウェザストリップにブチルテープ等の弾性変形可能なシール材を設けて段差を吸収できるようにし、シール材は両端に至るほど徐々に薄肉に形成してシール材端に隙間を生じさせないようにしたものが提案されている（特許文献２）。また高速走行時にドアが吸い出されて車外側に変形することによるドアウェザストリップのシール性の低下を解消するために、ウェザストリップが弾接する箇所の車体にアクリルテープを取付けたものも知られる（特許文献３）。 The lack of seal at the step is not limited to the case where the weather strip is elastically contacted with the step formed on the opening / closing body or the sealing surface of the vehicle body, but when the step is formed on the opening / closing body or the vehicle body to which the weather strip is attached, The same occurs in the step formed by the retainer end for holding the weather strip attached to the frame. In order to cope with this problem, an elastically deformable sealing material such as butyl tape is provided on the weatherstrip at the stepped portion so that the step can be absorbed, and the sealing material is formed so as to gradually become thinner toward both ends. The thing which did not produce a clearance gap at the end is proposed (patent document 2). In addition, in order to eliminate the deterioration of the sealing property of the door weather strip due to the door being sucked out and deformed to the outside of the vehicle when traveling at high speed, an acrylic tape is attached to the vehicle body where the weather strip elastically contacts ( Patent Document 3).
ウェザストリップには、フランジに差込んで取付けられる略Ｕ形断面のグリップ部と、該グリップ部に一体形成され、開閉体を閉じたとき、開閉体又は車体のシール面に弾接するシール部を備えたものがあり、その中には、グリップ部でフランジと共に車室に内張りされる内張り材の端末部を挟み込んで該端末部を固定するものも知られる（特許文献４）。 The weather strip includes a grip portion having a substantially U-shaped cross section that is attached by being inserted into a flange, and a seal portion that is integrally formed with the grip portion and elastically contacts the seal surface of the open / close body or the vehicle body when the open / close body is closed. Among them, there is also known one in which a terminal portion of a lining material lined in a passenger compartment together with a flange is sandwiched by a grip portion to fix the terminal portion (Patent Document 4).
特許文献１に開示されるウェザストリップのように、シール部の表層部を高発泡スポンジ層としたウェザストリップであっても段が大きくなると、シールしきれず、水洩れを生じ易くなる。 Even in the case of a weather strip in which the surface layer portion of the seal portion is a highly foamed sponge layer as in the weather strip disclosed in Patent Document 1, if the step is large, the seal cannot be completely sealed and water leakage is likely to occur.
特許文献２に開示されるものは、必要箇所にのみシール材をウェザストリップに取付ければよいが、シール材の取付はウェザストリップを開閉体又は車体に取付ける際に段に当たる箇所に取付ける必要があり、段に当たる箇所を想定してシール材を予めウェザストリップに取付けておくことは困難である。 Although what is disclosed by patent document 2 should just attach a sealing material to a weather strip only in a required location, when attaching a weather strip to an opening-closing body or a vehicle body, it is necessary to attach to the location which hits a step. It is difficult to preliminarily attach the sealing material to the weather strip in consideration of the place where it hits the step.
また特許文献３に開示されるものは、段部でのシール不足を解消するものではないし、テープを取付ける際にも取付箇所の目安がないため、所定位置に精度よく取付けるのは容易でない。 In addition, what is disclosed in Patent Document 3 does not solve the lack of sealing at the stepped portion, and since there is no indication of the attachment location when attaching the tape, it is not easy to attach it at a predetermined position with high accuracy.
特許文献４に開示されるウェザストリップは、車室に内張りされる内張り材の端部を固定するものであり、段でのシール不足を解消するものではない。 The weather strip disclosed in Patent Document 4 fixes an end portion of a lining material lined in a passenger compartment, and does not solve a lack of sealing at a step.
本発明は、自動車のドアやトランクリッド等の開閉体又は車体のいずれか一方に取付けられるウェザストリップが開閉体を閉じたとき、前記開閉体又は車体のいずれか他方のシール面に弾接して開閉体と車体との間をシールし、或いは前記開閉体又は車体に取付けられるウェザストリップと前記開閉体又は車体との間のシール構造において、ウェザストリップが弾接する開閉体又は車体のシール面或いはウェザストリップが取付けられる前記開閉体又は車体の取付面に形成される段に前述するような問題を生ずることなく当たって、段でのシールを確実に行うことができるシール構造を提供することを目的とする。 When a weather strip attached to one of an opening / closing body such as a door or a trunk lid of a car or a vehicle body closes the opening / closing body, the present invention opens and closes elastically against the other sealing surface of the opening / closing body or the vehicle body. In a sealing structure between the body and the vehicle body, or between the opening / closing body or the weather strip attached to the vehicle body and the opening / closing body or the vehicle body, the opening / closing body or the sealing surface of the vehicle body or the weather strip that elastically contacts the weather strip It is an object of the present invention to provide a seal structure that can reliably perform sealing at a step without causing the above-described problems to occur on the opening / closing body to which the member is attached or the step formed on the mounting surface of the vehicle body. .
請求項１に係る発明は、自動車のドアやトランクリッド等の開閉体又は車体のいずれか一方に取付けられるウェザストリップが開閉体を閉じたとき、開閉体または車体のいずれか他方のシール面に弾接して開閉体と車体との間をシールし、或いはウェザストリップと該ウェザストリップが取付けられる開閉体又は車体との間のシール構造において、前記ウェザストリップが弾接する車体又は開閉体のシール面、或いは前記ウェザストリップが取付けられる車体又は開閉体の取付面には、ウェザストリップから離れる方向に向かって凹となる段が形成されると共に、該段に向かって滑らかに湾曲ないし傾斜する湾曲部ないし傾斜部が形成され、前記段には該段を覆ってウェザストリップに弾接するパッチ状カバーが取付けられ、該パッチ状カバーは少なくともウェザストリップが当接する部分では、その端に至るほど徐々に薄肉に形成されてカバー端が前記段の湾曲部ないし傾斜部に位置して設けられ、該カバーの表面と、平坦部及び湾曲部ないし傾斜部を除く前記シール面或いは取付面とを面一ないしほぼ面一にしたことを特徴とする。 According to the first aspect of the present invention, when a weather strip attached to either an opening / closing body such as an automobile door or a trunk lid or a vehicle body closes the opening / closing body, an elastic member is applied to the other sealing surface of the opening / closing body or the vehicle body. In the sealing structure between the weather strip and the opening / closing body or the vehicle body to which the weather strip is attached, or the sealing surface of the vehicle body or the opening / closing body to which the weather strip elastically contacts, or On the mounting surface of the vehicle body or the opening / closing body to which the weather strip is attached, a step that becomes concave toward the direction away from the weather strip is formed, and a curved portion or an inclined portion that smoothly curves or inclines toward the step. And a patch-like cover that covers the step and elastically contacts the weather strip is attached to the step. At least at the part where the weather strip abuts, the thickness is gradually reduced toward the end, and the cover end is provided at the curved or inclined part of the step, and the surface of the cover, the flat part and the curved part are provided. The sealing surface or the mounting surface excluding the portion or the inclined portion is flush or substantially flush.
請求項２に係る発明は、請求項１に係る発明におけるシール構造が開閉体又は車体のいずれか一方に取付けられるウェザストリップが開閉体を閉じたとき、開閉体又は車体のいずれか他方のシール面に弾接して開閉体と車体との間をシールするシール構造であり、前記シール面を備えた開閉体又は車体は、シール面に沿い、かつ該シール面と一体のフランジを有する一方、前記段を覆って取付られるパッチ状カバーは前記フランジに添設される側縁部を備えており、前記フランジに差込まれる略Ｕ形断面のグリップ部と、該グリップ部と一体をなし、前記開閉体を閉じたとき、該開閉体又は車体のいずれか一方に弾接するシール部を備えた第２のウェザストリップの前記グリップ部又は前記フランジを覆って取付けられる略Ｕ形断面のトリムを前記フランジと該フランジに添設のカバー側縁部に差込んでカバー側縁部を前記フランジに固定することを特徴とする。 The invention according to claim 2 is such that when the weather strip attached to either the opening / closing body or the vehicle body closes the opening / closing body, the seal surface of either the opening / closing body or the vehicle body according to the invention according to claim 1 The opening / closing body or the vehicle body provided with the sealing surface has a flange integral with the sealing surface, while the sealing structure that seals between the opening / closing body and the vehicle body by elastic contact with the sealing surface. A patch-like cover attached to cover the flange includes a side edge portion attached to the flange, and is formed integrally with the grip portion having a substantially U-shaped cross section inserted into the flange, and the opening / closing body. A trim having a substantially U-shaped cross section that is attached to cover the grip portion or the flange of the second weather strip provided with a seal portion that elastically contacts either the opening / closing body or the vehicle body when the door is closed Characterized in that to secure the cover-side edge to the flange crowded difference in the cover edge of the additionally provided on the flange and the flange.
請求項１に係る発明によると、段には該段を覆うカバーが取付けられることにより段が解消されるため、ウェザストリップはシール部の表層部に高発泡スポンジ層を設けるなど段差を吸収できるような特別な構造にしなくてもカバーに弾接することでシールを確実に行うことができる。またカバーを取付ける際には、段が目安となって所定位置への取付けが容易かつ確実に行え、しかもこのカバーは開閉体又は車体の所定位置にウェザストリップの取付け前に予め取付けておくことができる。また、段に向かって湾曲部ないし傾斜部が形成され、この箇所に位置するカバー端は段より遠ざかる端に向かうほど徐々に薄肉に形成され、カバー端に形成される段は小さいため、カバー端はウェザストリップが弾接するシール面又はウェザストリップが取付けられる取付面に滑らかに続いてカバーの表面と前記シール面或いは取付面が面一ないしほぼ面一となり、カバー端でのシール不足を解消することができる。 According to the first aspect of the present invention, since the step is eliminated by attaching a cover covering the step to the step, the weatherstrip can absorb the step by providing a high foam sponge layer on the surface layer portion of the seal portion. Sealing can be reliably performed by elastically contacting the cover without using a special structure. Also, when installing the cover, the step can be used as a guide and can be easily and reliably attached to a predetermined position, and this cover should be attached in advance to the opening / closing body or the vehicle body at a predetermined position before the weather strip is attached. it can. In addition, a curved portion or an inclined portion is formed toward the step, and the cover end located at this position is gradually formed thinner toward the end farther from the step, and the step formed at the cover end is small. Smoothly follows the sealing surface to which the weatherstrip is elastically contacted or the mounting surface to which the weatherstrip is mounted, and the surface of the cover and the sealing surface or mounting surface are flush or almost flush with each other, thereby eliminating the lack of sealing at the cover edge. Can do.
請求項２に係る発明によると、パッチ状カバーはウェザストリップのグリップ部又はトリムに差込まれて固定され、カバーが外れたり、カバーの側端や側縁が浮く不具合を生ずることがない。また、段がフランジにまで及ぶ際にはフランジの段による隙間を吸収してシール性が向上する。 According to the second aspect of the present invention, the patch-like cover is fixed by being inserted into the grip portion or trim of the weatherstrip, so that the cover does not come off and the side edge or side edge of the cover does not float. Further, when the step reaches the flange, the gap due to the step of the flange is absorbed to improve the sealing performance.
以下、本発明の実施形態のシール構造について図面により説明する。

FIG. 6 is a side view of the cover 21 attached to the center pillar 1 and FIG. 7 is a cross-sectional view taken along the line AA of FIG. 8 and 8 show enlarged sectional views taken along line BB in FIG.
センターピラー１の前記段２はパネル２２上部にパネル２３下端部を重ねて溶接し、厚肉にした厚肉部分の端面により形成され、パネル２２は図８に示す例では、段２下の平坦部２２ａより車外側に斜め下方に向けて滑らかに湾曲ないし傾斜する湾曲部ないし傾斜部２２ｂを介して下方に延び、またパネル２３も下端部より車外側に斜め上方に向けて滑らかに湾曲ないし傾斜する湾曲部ないし傾斜部２３ａを介して上方に延びている。換言すれば前記湾曲部ないし傾斜部２２ｂ及び２３ａは、平坦部２２ａを介し、或いは介さないで段２に向かって滑らかに湾曲ないし傾斜して形成されている。 The step 2 of the center pillar 1 is formed by the end face of the thick portion where the lower end portion of the panel 23 is overlapped and welded to the upper portion of the panel 22 to make the wall thick. In the example shown in FIG. It extends downward via a curved portion or inclined portion 22b that smoothly curves or slopes obliquely downward from the portion 22a toward the vehicle exterior, and the panel 23 also smoothly curves or slopes obliquely upward from the lower end portion toward the vehicle exterior. It extends upward through a curved portion or inclined portion 23a. In other words, the curved portions or inclined portions 22b and 23a are smoothly curved or inclined toward the step 2 with or without the flat portion 22a.
カバー２１は図３、図４及び図７に示すように、正面の前壁２１ａと、該前壁２１ａの両端に一体形成される側壁２１ｂ及び２１ｃよりなって横断面が凹形をなし、センターピラー１に車外側から組付けられるようになっている。 As shown in FIGS. 3, 4 and 7, the cover 21 comprises a front front wall 21a and side walls 21b and 21c integrally formed at both ends of the front wall 21a. The pillar 1 can be assembled from the outside of the vehicle.
カバー２１の縦方向（センターピラー１に沿う方向）の断面は、図８に示すように中央の平坦部２１ｄと、上端に向かう程薄肉をなす上縁のヒレ部２１ｅと、下端に向う程薄肉をなす下縁のヒレ部２１ｆよりなり、平坦部２１ｄの裏面（取付面）には剥離紙（図示しない）付きの両面テープ２５が横方向に貼着されている。なお、図示する実施形態において、カバー上下縁の前記形状をなすヒレ部２１ｅ、２１ｆは、カバー上下縁の全長にわたって形成されているが、後述するウェザストリップ２７の中空シール部２９が当接する箇所にのみ形成されていてよい。 As shown in FIG. 8, the cover 21 has a cross section in the vertical direction (the direction along the center pillar 1), a flat portion 21 d at the center, a fin portion 21 e at the upper edge that is thinner toward the upper end, and a thinner portion toward the lower end. A double-sided tape 25 with release paper (not shown) is adhered to the back surface (mounting surface) of the flat portion 21d in the horizontal direction. In the illustrated embodiment, the fin portions 21e and 21f having the shape of the upper and lower edges of the cover are formed over the entire length of the upper and lower edges of the cover, but at the place where the hollow seal portion 29 of the weather strip 27 described later contacts. Only may be formed.
カバー２１をセンターピラー１に取付けるときには、両面テープ２５の剥離紙を剥離したのち、前記段２に被さるようにしてセンターピラー１に車外側から挿入又は嵌合する。そしてカバー２１をセンターピラー１に押付け、両面テープ２５を平坦部２２ｄに接着させて組付ける。 When attaching the cover 21 to the center pillar 1, the release paper of the double-sided tape 25 is peeled off, and then inserted or fitted into the center pillar 1 from the outside of the vehicle so as to cover the step 2. Then, the cover 21 is pressed against the center pillar 1, and the double-sided tape 25 is bonded to the flat portion 22d and assembled.
前述するカバー２１の取付けは、カバー２１をパネル２２の平坦部２２ｄに前記両面テープ２５以外の接着剤を用いて接着してもよいし、クリップその他の止着手段により止着してもよい。前記取付状態において、カバー２１は上縁のヒレ部２１ｅがパネル２３の下端部に湾曲ないし傾斜部２３ａに達するまで弾接し、また下側のヒレ部２１ｆがパネル２２の湾曲部ないし傾斜部２２ｂにラップ量ｄで弾接し、弾接状態で図９に示すように段２を覆うカバー２１の表面２１１（裏面の反対側）が平坦部２２ａ及び湾曲部ないし傾斜部２２ｂ、２３ａを除くパネル２２、すなわち湾曲部ないし傾斜部２２ｂより下方に延出する部分と、湾曲部ないし傾斜部２３ａより上方に延出する部分と面一ないしほぼ面一をなしている。 The cover 21 may be attached by adhering the cover 21 to the flat portion 22d of the panel 22 using an adhesive other than the double-sided tape 25, or may be fastened by a clip or other fastening means. In the attached state, the cover 21 is elastically contacted with the upper edge fin portion 21e at the lower end portion of the panel 23 until reaching the curved or inclined portion 23a, and the lower fin portion 21f is in contact with the curved portion or inclined portion 22b of the panel 22. The panel 22 except for the flat surface 22a and the curved or inclined portions 22b and 23a, the front surface 211 (opposite the back surface) of the cover 21 covering the step 2 as shown in FIG. That is, the portion extending downward from the curved portion or the inclined portion 22b and the portion extending upward from the curved portion or the inclined portion 23a are flush with or substantially flush with each other.
カバー２１の材質は、ゴムないし熱可塑性樹脂又は熱可塑性エラストマー（ＴＰＥ）等の弾性材よりなるが、これら弾性材の中では、前記カバーのヒレ部２１ｅ、２１ｆが前記パネル２２の湾曲部ないし傾斜部２２ｂ、２３ａに当接する機能性からゴム又はＴＰＥ、好ましくはこれらのスポンジ体で、更には比重０．０５〜０．４であることがより好ましい。 The material of the cover 21 is made of an elastic material such as rubber or thermoplastic resin or thermoplastic elastomer (TPE). Among these elastic materials, the fin portions 21e and 21f of the cover are curved or inclined of the panel 22. From the functionality of contacting the portions 22b and 23a, rubber or TPE, preferably these sponge bodies, more preferably 0.05 to 0.4 specific gravity.
図７に示すウェザストリップ２７は、開閉体であるドアの周りに取り付けられ、ドアフレーム３１にクリップ又は両面テープにより或いはリテーナを介して取付けられる基底部２８と、該基底部２８に一体形成され、ドア閉時にセンターピラー１に弾接するシール部の一例である中空シール部２９よりなっている。 The weather strip 27 shown in FIG. 7 is attached around a door as an opening / closing body, and is integrally formed with the base portion 28 attached to the door frame 31 with a clip or a double-sided tape or via a retainer, It consists of a hollow seal portion 29 that is an example of a seal portion that elastically contacts the center pillar 1 when the door is closed.
本実施形態のシール構造によると、ドア閉時には前記ウェザストリップ２７の中空シール部２９がセンターピラー１の長手方向に沿うシール面１ａ（図５）に弾接してシールするが、センターピラー１のシール面1ａに形成される前記段２には、該段２を覆うカバー２１が取付けられ、しかもカバー２１の表面２１１は、上下端に向かう程薄肉をなすカバー２１の上下縁が湾曲部ないし傾斜部２２ｂ、２３ａに弾接し、平坦部及び湾曲部ないし傾斜部を除く前記シール面或いは取付面と面一ないしほぼ面一をなすことによりカバー端を含め段がないか、カバー端に段ができたとしてもこの段は図２に示す段２、７より小さいため、中空シール部２９は前記シール面１ａに隙間なく弾接し、シールを確実に行うことができる。カバー２１を取付ける際には、前述するようなカバー２１の位置決め時にセンターピラー１の前記段２が目安となりうる。 According to the seal structure of the present embodiment, when the door is closed, the hollow seal portion 29 of the weather strip 27 is elastically contacted with the seal surface 1a (FIG. 5) along the longitudinal direction of the center pillar 1 for sealing. A cover 21 that covers the step 2 is attached to the step 2 formed on the surface 1a, and the upper and lower edges of the cover 21 that are thinner toward the upper and lower ends are curved or inclined portions. 22b and 23a are in elastic contact with the sealing surface or mounting surface except for the flat part, the curved part or the inclined part. However, since this step is smaller than steps 2 and 7 shown in FIG. 2, the hollow seal portion 29 is elastically brought into contact with the seal surface 1a without any gap, so that the sealing can be reliably performed. When the cover 21 is attached, the step 2 of the center pillar 1 can be used as a guide when positioning the cover 21 as described above.
カバー２１の取付は前述するように、センターピラー１に両面テープ２５によって接着され、この両面テープ２５は車体のシール面１ａを伝い落ちる雨水や洗浄水を受け止めて止水機能を果たすが、図示するようにカバー２１の左右両側縁の両面テープ２５がない箇所では、カバー側縁部が浮き上がり易く、これより漏水したり、外観を損ないがちになる。 As described above, the cover 21 is attached to the center pillar 1 by the double-sided tape 25. The double-sided tape 25 receives the rainwater and washing water that flows down the seal surface 1a of the vehicle body and performs a water stop function. Thus, in the part where the double-sided tape 25 on both the left and right side edges of the cover 21 is not provided, the cover side edge part is liable to float, and this tends to cause water leakage and damage the appearance.
この問題を解消するため図１０〜図１４に示す実施形態では、パッチ状のカバーとして、前記カバー２１の左右両側壁２１ｂ、２１ｃ端に外側方に延出する側縁部３１ａを一体形成したパッチ状のカバー３１が用いられ（図１０）、該カバー３１は両側縁部３１ａがセンターピラー両側のフランジ３２上に重ねるようにしてセンターピラー１に車外側から挿入又は嵌合され、両面テープ２５にてセンターピラー１に接着して組み付けられる（図１１）。 In order to solve this problem, in the embodiment shown in FIG. 10 to FIG. 14, as a patch-like cover, a patch in which side edges 31 a extending outward are integrally formed at the left and right side walls 21 b and 21 c of the cover 21. A cover 31 is used (FIG. 10), and the cover 31 is inserted or fitted to the center pillar 1 from the outside of the vehicle so that both side edges 31a overlap the flanges 32 on both sides of the center pillar. The center pillar 1 is attached and assembled (FIG. 11).
ついで芯金３３ｃを備えた略Ｕ形断面のグリップ部３３ａと、該グリップ部３３ａに一体形成され、開閉体であるドアを閉めたとき、該ドアに弾接するシール部としての中空シール部３３ｂよりなる第２のウェザストリップであるオープニングウェザストリップ３３のグリップ部３３ａが、フランジ３２と該フランジ３２上に重ねて添設されるカバー側縁部並びにインナーパネル４１のフランジ４２の三者に差込まれ、カバー側縁部３１ａをフランジ３２に固定する（図１２、図１３）。 Next, a grip portion 33a having a substantially U-shaped cross section provided with a core bar 33c, and a hollow seal portion 33b which is integrally formed with the grip portion 33a and elastically contacts the door when the door as an opening / closing body is closed. The grip part 33a of the opening weather strip 33, which is the second weather strip, is inserted into the flange 32, the cover side edge portion that is superimposed on the flange 32, and the flange 42 of the inner panel 41. The cover side edge 31a is fixed to the flange 32 (FIGS. 12 and 13).
本実施形態のシール構造によると、ドア閉時には、前記ウェザストリップ２７の中空シール部２９が前記したと同様、センターピラー１のシール面１ａに弾接してシールすると共に、センターピラー両側のフランジ３２に取付けされるオープニングウェザストリップ３３の中空シール部３３ｂがドアに弾接してシールする。また、カバー２１の左右両側縁がフランジ３２上に重ねて添設されオープニングウェザストリップ３３のグリップ部３３ａによって固定されるため、カバー側縁部が浮き上がらない。 According to the seal structure of the present embodiment, when the door is closed, the hollow seal portion 29 of the weather strip 27 is elastically contacted with the seal surface 1a of the center pillar 1 and sealed to the flanges 32 on both sides of the center pillar. The hollow seal portion 33b of the opening weather strip 33 to be attached is elastically contacted with the door for sealing. In addition, since the left and right side edges of the cover 21 are superimposed on the flange 32 and fixed by the grip part 33a of the opening weather strip 33, the cover side edge part does not rise.
また、センターピラー１に、シール面１ａからフランジ３２に至るまで横向きに形成される段２が形成された場合では、センターピラー１に取付けられるカバー３１は、シール面１ａに形成される段２を覆い、かつカバー側縁部がフランジ３２に重なり、該フランジ３２の段２を同様にして覆うことができ、フランジ３２の段２によって発生するオープニングウェザストリップ３３のグリップ部３３ａにおける隙間を覆うことができシール性を高めることができる。また、カバー３１の表面３１１は、前記カバー２１の表面２１１と同様、上下端に向う程、すなわち段２より遠ざかる程薄肉をなしており、カバー３１の上下縁がセンターピラー１の湾曲部ないし傾斜部２２ｂ、２３ａに弾接し、平坦部及び湾曲部ないし傾斜部を除く前記シール面或いは取付面と面一ないしほぼ面一をなすことにより、上下のカバー端には段がないか、段ができたとしてもこの段は図２に示す段２、７より小さくなり、そのためウェザストリップ２７の中空シール部２９は前記シール面１ａに隙間なく弾接し、シールを確実に行うことができる。さらにフランジ３２にセンターピラー１に設けられたと同様に段２の両側に該段に向かって滑らかに湾曲ないし傾斜する湾曲部ないし傾斜部２２ｂ、２３ａが形成され、カバー３１のカバー側縁部３１ａが上下端に向う程、すなわち段２より遠ざかる程薄肉をなしており、カバー側縁部３１ａの上下縁がフランジ３２の湾曲部ないし傾斜部２２ｂ、２３ａに弾接させると、オープニングウェザストリップ３３のグリップ部３３ａにおける段２による隙間を確実に無くすことができ、該グリップ部３３ａのシール性が高まる。 Further, in the case where the center pillar 1 is formed with a step 2 that is formed laterally from the seal surface 1a to the flange 32, the cover 31 attached to the center pillar 1 has the step 2 formed on the seal surface 1a. The cover side edge overlaps the flange 32 and can cover the step 2 of the flange 32 in the same manner, covering the gap in the grip portion 33a of the opening weather strip 33 generated by the step 2 of the flange 32. And sealability can be improved. Similarly to the surface 211 of the cover 21, the surface 311 of the cover 31 is thinned toward the upper and lower ends, that is, farther away from the step 2, and the upper and lower edges of the cover 31 are curved or inclined in the center pillar 1. The upper and lower cover ends are stepped or can be stepped by making elastic contact with the portions 22b and 23a and being flush or substantially flush with the sealing surface or mounting surface excluding the flat portion, the curved portion or the inclined portion. Even so, this step is smaller than the steps 2 and 7 shown in FIG. 2, so that the hollow seal portion 29 of the weather strip 27 is elastically contacted with the seal surface 1a without any gap, and the sealing can be surely performed. Further, similarly to the flange 32 provided on the center pillar 1, curved portions or inclined portions 22 b and 23 a that are smoothly curved or inclined toward the step are formed on both sides of the step 2, and the cover side edge portion 31 a of the cover 31 is formed. When the upper and lower edges of the cover side edge 31a are elastically brought into contact with the curved portions or inclined portions 22b and 23a of the flange 32, the grip of the opening weather strip 33 is formed. The gap due to the step 2 in the portion 33a can be reliably eliminated, and the sealing performance of the grip portion 33a is enhanced.
また、図１３ではカバー側縁部３１ａはフランジ３２ａの先端まであるが、先端までなくてもカバー側縁部３１ａが固定できる長さであればよい。つまりオープニングウェザストリップ３３のグリップ部３３ａには図示するように、フランジ３２ａの車外側に組み付く複数の突起３３ｅがあり、そのうちの一つの突起３３ｅにまで届けばよい。
また、フランジ３２ａの先端を覆って折り返し、インナーパネル４１のフランジ４２にも沿わせ、オープニングウェザストリップ３３のグリップ部３３ａの車内側の爪３３ｇによって固定されてもよい。
In FIG. 13, the cover side edge 31a extends to the tip of the flange 32a. However, the cover side edge 31a may be of a length that allows the cover side edge 31a to be fixed without reaching the tip. That is, as shown in the drawing, the grip portion 33a of the opening weather strip 33 has a plurality of protrusions 33e assembled to the outside of the flange 32a, and it is sufficient to reach one of the protrusions 33e.
Alternatively, the front end of the flange 32a may be covered, folded back along the flange 42 of the inner panel 41, and fixed by a claw 33g inside the vehicle of the grip portion 33a of the opening weather strip 33.
前記実施形態では、オープニングウェザストリップ３３のグリップ部３３ａがセンターピラー１のフランジ３２と、該フランジ３２の段２を覆ってフランジ３２に重ねられてカバー側縁部に差込んで取付けられる例を示したが、別の実施形態では、オープニングウェザストリップ３３から中空シール部２９を取り除いたような、フランジにフランジ隠しのため、取付けられる略Ｕ形断面のトリム（図示しない）がフランジと、該フランジに添設のカバー側縁部に差込まれ、カバー側縁部を固定する。 In the said embodiment, the grip part 33a of the opening weatherstrip 33 covers the flange 32 of the center pillar 1 and the step 2 of this flange 32, is overlapped with the flange 32, and is inserted and attached to the cover side edge part. However, in another embodiment, a substantially U-shaped trim (not shown) to be attached to the flange, such as removing the hollow seal portion 29 from the opening weatherstrip 33, has a flange and a flange attached to the flange. The cover side edge is fixed by being inserted into the attached cover side edge.
前記実施形態ではまた、オープニングウェザストリップ３３のグリップ部３３ａを段２のあるフランジ３２に、段２を覆うカバー側縁部と共に差込んで取付けた例を示したが、フランジ以外のウェザストリップの取付面においても該取付面に段があり、かつ該段を境にして前述するような湾曲部ないし傾斜部２２ｂ、２３ａが設けられる場合であっても、該段にカバー２１を取付けることでウェザストリップと取付面との間の隙間をなくし、前記と同様の効果を挙げることができる。 In the embodiment, the grip portion 33a of the opening weather strip 33 is attached to the flange 32 having the step 2 together with the cover side edge portion covering the step 2, but the weather strip other than the flange is attached. Even in the case where there is a step on the mounting surface and the curved portion or the inclined portions 22b and 23a as described above are provided with the step as a boundary, the weather strip can be provided by attaching the cover 21 to the step. The same effect as described above can be obtained by eliminating the gap between the mounting surface and the mounting surface.
また、ドア開口縁部に取付けられるウェザストリップ取付用のリテーナの端面により形成される段においても、該段を境にして車体とリテーナに前述するような湾曲部ないし傾斜部２２ｂ、２３ａが設けられる場合、カバー２１、３１を同様にして取付けることによリ図８及び図１４と同様、段での隙間をなくし、面一ないしほぼ面一なウェザストリップ取付面を形成するができる。 Also, in the step formed by the end face of the weatherstrip retainer attached to the edge of the door opening, the vehicle body and the retainer are provided with the curved portions or inclined portions 22b and 23a as described above with the step as a boundary. In this case, by attaching the covers 21 and 31 in the same manner, it is possible to eliminate the gap at the step and form a weather strip mounting surface that is flush or substantially flush, as in FIGS.
前記各実施形態は、カバー２１、３１をセンターピラー１に形成される厚肉部分端の段２に取付けた例を示したが、図１に示すように補強材等５、６の両端に形成される段７と、該段７を境にして前述するような湾曲部ないし傾斜部２２ｂ、２３ａが設けられる別の実施形態において、カバー２１、３１が前記段７に同様にして取付けられ、これにより前記実施形態と同様の効果を挙げることができる。 In each of the above embodiments, the covers 21 and 31 are attached to the thick part end step 2 formed on the center pillar 1, but as shown in FIG. In another embodiment in which the step 7 and the curved or inclined portions 22b and 23a as described above are provided with the step 7 as a boundary, the covers 21 and 31 are attached to the step 7 in the same manner. Thus, the same effect as in the above embodiment can be obtained.
前記各実施形態は車体のドア開口縁部のシール面或いはウエザストリップ取付面に段があり、該段を境にして前述するような湾曲部ないし傾斜部２２ｂ、２３ａが設けられる場合において、カバー２１、３１を取付けた例を示すものであるが、別の実施形態では、ドア或いはトランクリッドに形成される段と、該段を境にして前述するような湾曲部ないし傾斜部２２ｂ、２３ａが設けられる場合に前記カバー２１、３１が取付けられて段をなくすと共に、面一ないしほぼ面一なシール面が形成され、ドア或いはトランクリッド閉時にウェザストリップがカバー２１、３１に弾接してシールするようにされる。またパネルとパネルの重ね合わせによる段だけでなく、パネルと内装材の重ねあわせによる段など、全く異なる異材同士による段であってもよく、またそれらが溶接などのように接続されている必要もなく、さらには単一材質であっても平面に段と呼べる極端な***が発生している箇所において、本発明は有効に用いることができる。 In each of the above embodiments, there is a step on the sealing surface or weather strip mounting surface of the door opening edge of the vehicle body, and when the curved portions or inclined portions 22b and 23a as described above are provided with the step as a boundary, a cover is provided. In another embodiment, a step formed on a door or a trunk lid and a curved portion or inclined portion 22b, 23a as described above with the step as a boundary are shown. When provided, the covers 21 and 31 are attached to eliminate the step, and a flush or almost flush sealing surface is formed. When the door or the trunk lid is closed, the weather strip is elastically contacted with the covers 21 and 31 for sealing. To be done. Also, not only the step by overlapping the panel and the panel, but also the step by completely different materials such as the step by overlapping the panel and the interior material, and they need to be connected by welding etc. Furthermore, the present invention can be used effectively in a place where even if it is a single material, there is an extreme bulge that can be called a step on the plane.
