Description

本発明は、熱可塑性エラストマー（ＴＰＥ）で形成した自動車のグラスランチャンネルに関するものである。   The present invention relates to an automotive glass run channel formed of a thermoplastic elastomer (TPE).

図１および図２を参照して説明する。自動車のドアパネル２には、ドアガラス３の昇降をシール性を保ちながらガイドするグラスランチャンネルが設けられている。従来、このグラスランチャンネルは、ＥＰＤＭやＰＶＣを押出成形することによって成形されているが（コーナー部は型成形による）、近年において求められている自動車の軽量化の中で、ＥＰＤＭやＰＶＣよりも比重の小さい非発泡熱可塑性エラストマー製のグラスランチャンネル１０が提供されはじめている。   This will be described with reference to FIGS. The door panel 2 of the automobile is provided with a glass run channel that guides the raising and lowering of the door glass 3 while maintaining the sealing property. Conventionally, the glass run channel is formed by extrusion molding of EPDM or PVC (the corner portion is formed by molding). However, the specific gravity is higher than that of EPDM or PVC in light of the weight reduction of automobiles required in recent years. A glass run channel 10 made of a small non-foamed thermoplastic elastomer is beginning to be provided.

しかし、自動車のさらなる軽量化が求められており、こうした要求に応えるべく、例えば、非発泡ＴＰＥ製グラスランチャンネル１０の基部１０ａを発泡させることが考えられるが、そうすると、機械的強度が要求される基部が脆弱化してしまうので好ましくない。基部１０ａは、ドアパネル２に組付けられ、ドアガラス３に摺動するリップ部１０ｂを支持する部材であるため十分な機械的強度が要求される。従って、基部１０ａとしての機能（強度）を保ちつつ、その軽量化を図ることはきわめて難しい。   However, there is a demand for further weight reduction of automobiles, and in order to meet these demands, for example, it is conceivable to foam the base portion 10a of the glass run channel 10 made of non-foamed TPE. Is not preferable because it becomes weak. Since the base portion 10a is a member that is assembled to the door panel 2 and supports the lip portion 10b that slides on the door glass 3, a sufficient mechanical strength is required. Therefore, it is extremely difficult to reduce the weight while maintaining the function (strength) as the base 10a.

ちなみに、これまでのゴム製のグラスランチャンネルにおいては、押出成形時に発泡化させているものもあるが、基部としての機能を維持するために、その発泡倍率は１．２以下であり、比重も１．０前後に留まっている。そのため、効果的な軽量化を図るには至っていない。   Incidentally, some conventional glass run channels made of rubber are foamed at the time of extrusion molding, but in order to maintain the function as a base, the foaming ratio is 1.2 or less and the specific gravity is also 1 It remains around 0. Therefore, effective weight reduction has not been achieved.

本発明はこうした点に鑑み創案されたもので、十分な機械的強度を保持しつつ、効果的な軽量化を図った自動車のグラスランチャンネルおよびその製造方法を提供することを課題とする。   The present invention was devised in view of these points, and it is an object of the present invention to provide a glass run channel of an automobile and a method of manufacturing the same, which can effectively reduce the weight while maintaining sufficient mechanical strength.
