Abstract

To provide an automobile beltline portion sound insulating structure capable of improving a sound insulation state of an automobile interior at a door glass closed time to a high level and an automobile door glass. An automobile beltline portion sound insulating structure including a door panel having two panel boards facing each other having seal members along the beltline respectively, and a door glass provided between the two panel boards having a main body and a first viscoelastic member having a Young's modulus lower than that of the seal member, in a lower portion of one main surface of the main body, the seal member positioned on the side of the one main surface having two or more lip portions, wherein the first viscoelastic member is positioned between the two lip portions while abutting on at least a part of the seal member at the door glass closed time.

Description

technical field [0001] The present invention relates to an automobile waistline sound insulation structure and an automobile door glass used in the sound insulation structure. Background technique [0002] Conventionally, as one of the methods of improving the sound insulation performance of the automobile interior, a method of providing a sound insulation structure along the waistline of the automobile has been employed. As this soundproof structure, for example, Patent Document 1 discloses a soundproof structure in which, when the door glass is closed, the lower end portions of the outer seal portion and the inner seal portion attached to the door panel and the portion corresponding to the lower end portion of the glass A soundproof material is provided on one of them, and a protrusion elastically contacting the soundproof material is provided on the other side. [0003] In the sound insulation structure described in Patent Document 1, when the door glass is closed, the g...
