Description
本発明は、自動車アクセサリフロアマットに関し、より詳細には、成形されたマットに関する。
周囲の雑音を最小化することが望ましいということがしばしばある。例えば、自動車の内部にいる人間の快適性を改善するためには、自動車の内部の雑音レベルを低くすることが望ましいことがある。このような雑音の源は、路面、タイヤ構造、ドライブトレイン雑音、排気雑音、シャシおよびサスペンション雑音、風による雑音などを含み、あるいはこれらにより影響される。自動車製造業者は、キャビン雑音を低くするために多大の努力および費用を費やしている。
本発明の実施形態によれば、多層吸音マットは、露出穴が中に形成されている基層を含む。表面層は、基層に隣接して配置されている。吸音層は、基層と表面層との間に配置されている。吸音層は、露出穴全体にわたり広がっている暴露部分を含み、基層は、吸音層に結合されている。
以下、本発明を、好ましい実施形態が示されている添付図面を参照して、より詳細に説明する。しかしながら、本発明は、多数の異なる形で実施でき、本明細書に記載の実施形態に制限されるものではない。すなわち、これらの実施形態は、この開示が完璧で完全になり、当業者に本発明の範囲を完全に伝えるために記載されている。全体にわたり、同一の参照番号は同一の要素を示している。図中において、層、構成要素あるいは領域は、分かり易くするために誇張されている。
st Method for Airflow Resistance of Acoustic Materials"に従って測定した約200Raylの通気抵抗値を
有し、したがって通気性を有し、また耐水性も有している。層120は連続層である(図4参照)。吸音層120を形成する材料は、マット100の中に成形する前、材料の厚さ全体にわたりおよび/または材料の幅および/または長さ全体にわたり、異なる密度の複数の部分を有している。層120は、層130の色と異なるあるいは対照的である色を有することもある。
