Description

本発明は、リアドアとフロントドアとの間(見切り部)をシールするウエザーストリップ構造に関するものである。  The present invention relates to a weather strip structure for sealing between a rear door and a front door (parting portion).

従来は図3に示すようなスライド式リアドア3を備えた自動車において、リアドア3を閉じたときの状態をA−A線に沿う断面図として図4に示す。図4において、センターピラー1を中心にして前方にはフロントドア2が、また後方にリアドア3が位置する。ここで、リアドア3は矢線pで示したような軌跡を描いて開閉する。リアドア3の前端部内側に取付基部11をクリップ10で固定されたウエザーストリップ12が取付けられ、この取付基部11に一体に設けられたリップ状のシール部13がリアドア3の閉時に前記フロントドア2の後端部内面に当接してフロントドア2とリアドア3の間(見切り部)をシールするようになっている。  FIG. 4 shows a state where the rear door 3 is closed in a vehicle having a sliding rear door 3 as shown in FIG. In FIG. 4, a front door 2 is located in front of the center pillar 1 and a rear door 3 is located in the rear. Here, the rear door 3 opens and closes by drawing a locus as indicated by an arrow p. A weather strip 12 having a mounting base 11 fixed by a clip 10 is attached to the inside of the front end of the rear door 3, and a lip-shaped seal portion 13 provided integrally with the mounting base 11 is used when the rear door 3 is closed. It abuts against the inner surface of the rear end portion of the rear door and seals between the front door 2 and the rear door 3 (parting portion).

ところが、前記ウエザーストリップ12がリアドア3の前端部内側に取付けられた際、取付基部11に対しリップ状のシール部13が略直線状に設けられているため、ドア閉時このシール部13が車内側に浮き上がり外観とシール性が損なわれ易いという不具合があった。また、図1に示す如くセンターピラー1の幅h1が図4の場合の幅h2に比べて狭い場合、取付基部11のリアドア3の前端部内側への取付けスペースが狭くなり取付け難いという問題があった。
そこで、本発明はかかる従来の課題に鑑みて、ドア閉時シール部が車内側に浮き上がり難くして外観とシール性の向上を図り、かつセンターピラーの幅が狭く取付基部のリアドアの取付けスペースが狭い場合でも取付けを容易にしたドア見切り部のウエザーストリップ構造を提供することを目的とする。
However, when the weather strip 12 is attached to the inner side of the front end of the rear door 3, the lip-shaped seal portion 13 is provided in a substantially straight line with respect to the attachment base portion 11. There was a problem that the external appearance and the sealing performance were easily lost. Further, as shown in FIG. 1, when the width h1 of the center pillar 1 is narrower than the width h2 in FIG. 4, there is a problem that the mounting space inside the front end portion of the rear door 3 of the mounting base 11 becomes narrow and it is difficult to mount. It was.
Therefore, in view of such conventional problems, the present invention makes it difficult for the seal portion when the door is closed to rise to the inside of the vehicle, improving the appearance and sealing performance, and reducing the width of the center pillar and reducing the mounting space for the rear door of the mounting base. It is an object of the present invention to provide a weather strip structure for a door parting portion that can be easily installed even in a narrow space.

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、リアドア3の前端部近傍に取付けられる取付基部8に一体に設けられて、該リアドア3の閉時に、センターピラー1の前側面付近でフロントドア2の後端部に当接する中空状のシール部9を備えたウエザーストリップ構造において、前記リアドア3の前端部に比較的近い位置に該リアドア3のインナープレート5が所定角度β立ち上がる縦壁6が形成されると共に、ウエザーストリップ7が前記リアドア3の前端部に略平行の前記シール部9に対し、前記取付基部8が前記縦壁6に沿う如く屈曲成形され、リアドア3への取付けの際前記取付基部8が縦壁6に固定されて成るものであり、
また、図2に示す前記ウエザーストリップ7の取付基部8の中空状のシール部9に対する屈曲角度αが、前記リアドア3の前端部に対する前記縦壁6の立ち上がり角度βよりも幾分小さ目に屈曲成形され、ウエザーストリップ7の取付基部8が縦壁6に固定された際、前記シール部9が前記リアドア3の前端部に対し押圧する如く構成されたものである。
In order to achieve such an object, the configuration of the present invention is provided integrally with a mounting base 8 that is mounted near the front end of the rear door 3 as shown in FIG. In a weather strip structure having a hollow seal portion 9 that abuts against the rear end portion of the front door 2 near the front side surface, the inner plate 5 of the rear door 3 is positioned at a predetermined angle at a position relatively close to the front end portion of the rear door 3. A vertical wall 6 rising β is formed, and a weather strip 7 is bent with respect to the seal portion 9 substantially parallel to the front end portion of the rear door 3 so that the mounting base 8 is bent along the vertical wall 6. The mounting base 8 is fixed to the vertical wall 6 when mounted on the wall,
Also, the bending angle α with respect to the hollow seal portion 9 of the mounting base portion 8 of the weather strip 7 shown in FIG. 2 is bent slightly smaller than the rising angle β of the vertical wall 6 with respect to the front end portion of the rear door 3. When the mounting base 8 of the weather strip 7 is fixed to the vertical wall 6, the seal portion 9 is configured to press against the front end portion of the rear door 3.

発明の効果The invention's effect

本発明の見切り部のウエザーストリップ構造は、リアドア3の前端部より比較的近い位置にインナープレート5が所定角度立ち上がる縦壁6が形成されると共に、ウエザーストリップ7が、リアドア3の前端部に略平行の中空状のシール部9に対し取付基部8が前記縦壁6に沿う如く屈曲成形され、また該取付基部8の屈曲成形の角度αが、リアドア3の前端部4に対する前記縦壁6の立ち上がり角度βよりも幾分小さ目に屈曲成形されているため、センターピラー1の幅h1が狭く取付基部8のリアドア3前端部内側への取付けスペースが狭い場合でも取付け容易となり、またドア閉時にシール部9が車内側に浮き上がるのを防止してシール性の向上を図ることができるという特長がある。  In the weather strip structure of the parting portion of the present invention, a vertical wall 6 where the inner plate 5 rises by a predetermined angle is formed at a position relatively closer to the front end portion of the rear door 3, and the weather strip 7 is substantially at the front end portion of the rear door 3. The mounting base 8 is bent with respect to the parallel hollow seal portion 9 along the vertical wall 6, and the angle α of the bending of the mounting base 8 with respect to the front end 4 of the rear door 3 is Because the center pillar 1 is bent and formed slightly smaller than the rising angle β, the center pillar 1 can be easily mounted even when the width h1 of the center pillar 1 is narrow and the mounting space inside the front end of the rear door 3 is narrow. There is a feature that the sealing performance can be improved by preventing the portion 9 from floating on the inside of the vehicle.

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はスライド式リアドアを備えた自動車の側面図であり、図1はそのA−A線に沿う断面図である。センターピラー1を中心にして前方にはフロントドア2が、また後方にリアドア3が位置している。リアドア3はセンターピラー1の幅h1が図4に示すセンターピラー1aの幅h2に比べてがかなり狭いため、前端部4より比較的近い位置にインナープレート5が所定角度立ち上がる縦壁6が形成されている。  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 3 is a side view of an automobile provided with a sliding rear door, and FIG. 1 is a cross-sectional view taken along the line AA. A front door 2 is located in front of the center pillar 1 and a rear door 3 is located in the rear. Since the rear door 3 has a width h1 of the center pillar 1 that is considerably narrower than the width h2 of the center pillar 1a shown in FIG. 4, a vertical wall 6 is formed at which the inner plate 5 rises at a predetermined angle at a position relatively closer to the front end portion 4. ing.

前記リアドア3に取付けられるウエザーストリップ7は、取付基部8と一体に設けた中空状のシール部9から構成され、リアドア3の前端部に略平行の中空状のシール部9に対し取付基部8が前記縦壁6に沿う如く屈曲成形されている。また、ウエザーストリップ7は中空状のシール部9に対する取付基部8の屈曲角度αが、一点鎖線で示す如く前記リアドア3の前端部に対する前記縦壁6の立ち上がり角度βよりも幾分小さ目に屈曲成形されている。従って、ウエザーストリップ7が取付基部8を縦壁6にクリップ10又は両面テープで固定して取付けられた際に、ドア閉時前記シール部9が前記屈曲角度αの小さい分縮設されるため、前記リアドア3の前端部に対し押圧してシール性を向上する。なお、前記シール部9が中空状の場合はリップ状の場合よりも組み付けのバラツキに追従し易く、またドア閉時見切り部での飛び出しが中空状の方が発生し難い。
また、本発明は実施例でリアドア3をスライド式の場合につき説明したが、ヒンジ式のリアドアにも適用される。
The weather strip 7 attached to the rear door 3 is composed of a hollow seal portion 9 provided integrally with the attachment base portion 8, and the attachment base portion 8 is attached to the hollow seal portion 9 substantially parallel to the front end portion of the rear door 3. It is bent so as to be along the vertical wall 6. Further, the weather strip 7 is bent so that the bending angle α of the mounting base portion 8 with respect to the hollow seal portion 9 is somewhat smaller than the rising angle β of the vertical wall 6 with respect to the front end portion of the rear door 3 as indicated by a dashed line. Has been. Accordingly, when the weather strip 7 is attached to the vertical wall 6 with the attachment base 8 fixed with the clip 10 or the double-sided tape, the seal portion 9 is contracted by a small bending angle α when the door is closed. The sealing is improved by pressing against the front end of the rear door 3. When the seal portion 9 is hollow, it is easier to follow the assembly variation than when the seal portion 9 is lip-shaped, and the protrusion at the parting portion when the door is closed is less likely to occur.
Further, the present invention has been described with respect to the case where the rear door 3 is a sliding type in the embodiment, but the present invention is also applicable to a hinged rear door.

図2に示すように、本発明のウエザーストリップの中空シール部は、フロントドアとリアドアの見切り部をシールするすることが主目的のため、中空シール部はセンターピラー部と弾接させる設定にはしていない。また、中空部は取付基部の側壁に連結され中空部の車内側はフロントドア先端部と略平行な車内側側壁と車外側に凸の山形の車外側壁からなり、車外側壁の凸の山形の頂部がフロントドア後端とリアドア先端の見切り部に位置させ、凸の山形部がはみ出さないように略面一となるようにはいちしている。
また、図2に示すように中空状のシール部9はシール性の観点からスポンジゴムとするのが好ましく、取付基部8は取付け時の剛性確保の観点からソリッドゴムとし肉厚とするのが好ましい。又取付基部のクリップ固定部の肉厚についてはクリップ形状に合わせて多少薄肉としてもよい。また、ドアパネル先端折り返し部車内側には防錆目的のペイントシーラーが設けられるのが通常であるため、このペイントシーラーとの干渉を防止するために基底部立ち上がり部に凹部を設けるのが好ましい。また、本ウエザーストリップはスライドドア車とヒンジドア車の両方に適用可能である。
As shown in FIG. 2, the hollow seal portion of the weather strip according to the present invention is mainly intended to seal a parting portion of the front door and the rear door, so that the hollow seal portion is elastically contacted with the center pillar portion. Not done. In addition, the hollow portion is connected to the side wall of the mounting base, and the inner side of the hollow portion is composed of a vehicle inner side wall substantially parallel to the front door front end portion and a mountain-shaped vehicle outer wall convex to the vehicle outer side. The top is positioned at the parting part at the rear end of the front door and the front end of the rear door so that the convex chevron does not protrude.
In addition, as shown in FIG. 2, the hollow seal portion 9 is preferably made of sponge rubber from the viewpoint of sealing properties, and the attachment base portion 8 is preferably made of solid rubber and thick from the viewpoint of securing rigidity at the time of attachment. . Further, the thickness of the clip fixing portion of the mounting base may be made somewhat thin according to the clip shape. Further, since a paint sealer for the purpose of preventing rusting is usually provided inside the door panel front end folding portion, it is preferable to provide a recess at the base rising portion in order to prevent interference with the paint sealer. Further, the weather strip can be applied to both a sliding door vehicle and a hinge door vehicle.
