発明の効果The invention's effect

本発明の自動車用ドアのシール部材３又は８は、グリップ部４又は９とリップ部７又は１３との間に屈曲し易い薄肉平板状の連接部６又は嵌合用連接部１２を接続して成るので、従来のリップ部１７の付け根部１８が断面略三角形の厚肉で形成された場合と異なり、ドアサッシュ１のコーナー部Ｃの曲率ｒの小さい部分でも組み付けが容易となるという特長がある。  The automotive door seal member 3 or 8 according to the present invention is formed by connecting a thin flat plate-like connecting portion 6 or a fitting connecting portion 12 between the grip portion 4 or 9 and the lip portion 7 or 13. Therefore, unlike the case where the base portion 18 of the conventional lip portion 17 is formed with a thick wall having a substantially triangular cross section, there is a feature that it is easy to assemble even in a portion where the curvature r of the corner portion C of the door sash 1 is small.

以下、本発明の実施例を図に基づいて詳細に説明する。第１の発明は図４及び図２に示す如く、自動車用ドアＤのドアサッシュ１の側壁２に、シール部材３が取付けられている。
なお、ドアサッシュ１の車外側には、リテーナＲを介し中空状シールＳが取付けられている。
また、図１に示す如く前記シール部材３は、ドアサッシュ１の側壁２の表面を覆う帯状のグリップ部４を形成し、該グリップ部４の上部に前記側壁２の上端に係合する係合溝部５を形成している。また、この係合溝部５に薄肉平板状の連接部６が一体に接続され、更に連接部６には、ドア閉時に車体開口縁Ｂに圧接しシールするリップ部７が接続されている。なお、グリップ部４の下部には側壁２の下端に係合する係合溝部５ａが形成され、グリップ部４の表面にはモール４ａが貼り付けられている。
上記シール部材３のうち、グリップ部４、係合溝部５及び連接部６はＰＰ等の高剛性の樹脂材で形成され、リップ部７はＴＰＯ等の軟質又は発泡樹脂で形成されており、これらは一体的に押出し成形されている。
前記グリップ部４とリップ部７との間に、屈曲し易い薄肉平板状の連接部６が介在されているため、ドアサッシュ１のコーナー部Ｃの曲率ｒの小さい部分の組み付けが容易となる。Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the first invention, as shown in FIGS. 4 and 2, a seal member 3 is attached to a side wall 2 of a door sash 1 of an automobile door D.
A hollow seal S is attached to the outside of the door sash 1 via a retainer R.
Further, as shown in FIG. 1, the seal member 3 forms a band-like grip portion 4 that covers the surface of the side wall 2 of the door sash 1, and engages with the upper end of the side wall 2 at the upper portion of the grip portion 4. A groove portion 5 is formed. Further, a thin flat plate-like connecting portion 6 is integrally connected to the engaging groove portion 5, and a lip portion 7 is connected to the connecting portion 6, which presses and seals against the vehicle body opening edge B when the door is closed. An engaging groove 5 a that engages with the lower end of the side wall 2 is formed at the lower part of the grip 4, and a molding 4 a is attached to the surface of the grip 4.
Of the sealing member 3, the grip part 4, the engaging groove part 5 and the connecting part 6 are formed of a highly rigid resin material such as PP, and the lip part 7 is formed of a soft or foamed resin such as TPO. Are integrally extruded.
Since the thin flat plate-like connecting portion 6 that is easily bent is interposed between the grip portion 4 and the lip portion 7, it is easy to assemble a portion having a small curvature r of the corner portion C of the door sash 1.

前記高剛性の樹脂材としては、ポリエチレン、ポリプロピレン、ポリスチレン、ポリアミド等が挙げられるが、曲げ弾性率が１０００〜６０００Ｍｐａであることが好ましい。１０００Ｍｐａであると剛性が不足し、６０００Ｍｐａを越える場合でも実用上支障ないが材料コストが顕著に高くなるため安廉価で製造するためには６０００Ｍｐａ以下が好ましい。中でもポリプロピレンが、グリップ部４に好適な２０００〜３０００の曲げ弾性率を示すこと及び安廉価であることからより好ましい。
前記軟質又は発泡樹脂としては、オレフィン系熱可塑性エラストマー（ＴＰＯ）、スチレン系熱可塑性エラストマー（ＴＰＳ）、ウレタン系熱可塑性エラストマー（ＴＰＵ）等が挙げられるが、ポリプロピレンと接着性の良いＴＰＯが好ましい。
前記軟質樹脂の硬度は、ショアＡ３５度以上７５度以下の範囲のものが好ましい。ショアＡ３５度未満であると、リップ部７の剛性が不足してシール性が低下し、ショアＡ７５度以上では、リップ部７の剛性が大きくなり過ぎドアサッシュ１のコーナー部Ｃへの取付け時に曲率ｒの追従性が不足してリップ部７が変形しシール性が低下する。そのため、ドア閉時にボディ塗装板金塗膜が剥れ易くなる。
前記軟質又は発泡ゴムとしては、ＥＰＤＭソリッドゴム、ＣＲソリッドゴム、ＳＢＲソリッドゴム等が挙げられるが、耐候性が良好である点からＥＰＤＭソリッドゴムが好ましい。Examples of the high-rigidity resin material include polyethylene, polypropylene, polystyrene, polyamide, and the like, but the flexural modulus is preferably 1000 to 6000 Mpa. If it is 1000 Mpa, the rigidity is insufficient, and even if it exceeds 6000 Mpa, there is no practical problem, but the material cost is remarkably high, so that it is preferably 6000 Mpa or less in order to manufacture at a low price. Among these, polypropylene is more preferable because it exhibits a bending elastic modulus of 2000 to 3000 suitable for the grip portion 4 and is inexpensive.
Examples of the soft or foamed resin include olefin-based thermoplastic elastomers (TPO), styrene-based thermoplastic elastomers (TPS), urethane-based thermoplastic elastomers (TPU), and TPO having good adhesion to polypropylene is preferable.
The hardness of the soft resin is preferably in the range of Shore A 35 ° to 75 °. If the Shore A is less than 35 degrees, the rigidity of the lip 7 is insufficient and the sealing performance is deteriorated. If the Shore A is 75 degrees or more, the rigidity of the lip 7 becomes too large and the curvature of the door sash 1 when it is attached to the corner C The followability of r is insufficient, and the lip portion 7 is deformed to reduce the sealing performance. Therefore, the body-coated sheet metal coating film is easily peeled off when the door is closed.
Examples of the soft or foamed rubber include EPDM solid rubber, CR solid rubber, SBR solid rubber and the like, and EPDM solid rubber is preferable from the viewpoint of good weather resistance.

次に、第２の発明につき説明する。前記第１の発明は、前記シール部材３が一体的に押出し成形されて成り製造コストの面で有利となるが、リップ部５が軟性樹脂材であるためゴム材の場合に比べ撓み性、コーナー部での追従性、ドア閉時のシール性等で多少劣る難点があり、それを克服するためリップ部１３部分をゴム材にして解決を図ったものである。
即ち、図３に示す如くシール部材８は、ドアサッシュ１の側壁２の表面を覆う帯状のグリップ部９を形成し、該グリップ部９の上部に前記側壁２の上端に係合する係合溝部１０を形成している。また、この係合溝部１０に嵌合凹溝１１を有した薄肉平板状の嵌合用連接部１２が接続されている。これらグリップ部９、係合溝部１０及び嵌合用連接部１２はＰＰ等の高剛性の樹脂材で一体的に形成されている。なお、グリップ部９の下部には側壁２の下端に係合する係合溝部１０ａが形成され、グリップ部９の表面にはモール９ａが貼り付けられている。
一方、ゴム材のリップ部１３が設けられ、下端に断面略Ｔ字状の係合端部１４が、前記嵌合用連接部１２の嵌合凹溝１１に嵌め込まれる如く形成されている。Next, the second invention will be described. The first invention is advantageous in terms of manufacturing cost because the seal member 3 is integrally extruded, but the lip portion 5 is made of a soft resin material, so that it has flexibility and corners compared to a rubber material. In order to overcome this problem, the lip portion 13 is made of a rubber material in order to overcome these disadvantages.
That is, as shown in FIG. 3, the seal member 8 forms a band-like grip portion 9 that covers the surface of the side wall 2 of the door sash 1, and an engagement groove portion that engages with the upper end of the side wall 2 on the grip portion 9. 10 is formed. Further, a thin flat plate-like fitting connecting portion 12 having a fitting groove 11 is connected to the engaging groove portion 10. The grip portion 9, the engagement groove portion 10, and the fitting connecting portion 12 are integrally formed of a highly rigid resin material such as PP. An engaging groove portion 10 a that engages with the lower end of the side wall 2 is formed in the lower portion of the grip portion 9, and a molding 9 a is attached to the surface of the grip portion 9.
On the other hand, a lip portion 13 of rubber material is provided, and an engaging end portion 14 having a substantially T-shaped cross section is formed at the lower end so as to be fitted into the fitting concave groove 11 of the fitting connecting portion 12.

かくして、前記シール部材８は前記嵌合用連接部１２の嵌合凹溝１１に、リップ部１３の係合端部１４が嵌め込まれて一体化される。従って、シール部材８が図２に示す如くドアサッシュ１の側壁２に組み付けられた際、リップ部１３がゴム材のため撓み性、コーナー部での追従性及びドア閉時の優れたシール性が発揮される。また、リップ部１３の鎖線で示す表面部分Ｍが、磁気を帯びたゴム材で形成されることにより、リップ部１３のシール性が一層向上される。
図４に示すドアＤの湾曲部Ｃや鋭角部Ｐに沿わせて前記シール部材３、８を組み付ける方法は下記の如くである。
１、一定曲率ｒであれば、押出し直後にローラー等により連続的に曲げることができる。
２、一定曲率ｒでなければ、押出部を加熱後Ｒ治具や金型に曲げてセット加熱冷却する。
３、鋭角部Ｐに対しては、各々を斜めカット後過熱溶着等により接合する。Thus, the sealing member 8 is integrated by fitting the engaging end portion 14 of the lip portion 13 into the fitting concave groove 11 of the fitting connecting portion 12. Therefore, when the seal member 8 is assembled to the side wall 2 of the door sash 1 as shown in FIG. 2, the lip portion 13 is a rubber material, so that it has flexibility, followability at the corner portion, and excellent sealing performance when the door is closed. Demonstrated. In addition, the surface portion M indicated by the chain line of the lip portion 13 is formed of a magnetic rubber material, so that the sealing performance of the lip portion 13 is further improved.
The method of assembling the sealing members 3 and 8 along the curved portion C or the acute angle portion P of the door D shown in FIG. 4 is as follows.
1. If the curvature r is constant, it can be continuously bent by a roller or the like immediately after extrusion.
2. If the curvature is not constant r, the extruded portion is heated and then bent into an R jig or a mold and set to heat and cool.
3. For the acute angle portion P, each is joined by overheating welding after oblique cutting.
