摘要： The provided articles, assemblies, and methods use a non-woven fibrous web (50) having one or more layers (60) that are densified in situ to provide a layer that is densified relative to one or more adjacent layers, collectively within a unitary non-woven construction. The non-woven web (50) can be made from fibers having a composition and/or structure that resist shrinkage induced by polymer crystallization when subjected to high temperatures. Advantageously, the provided non-woven webs (50) can be molded to form a three-dimensional shaped article that displays dimensional stability.

摘要： The inventive fastener member, fastener structure, and support member can reduce rattling and noise without reducing the ease of assembly. The fastener member10 includes guided portions 12A, 12B that are guided in the mounting direction D1 by guide portions 22A, 22B. Elastically deforming portions 30A, 30B formed on the guided portions 12A, 12B can elastically deform in a direction that intersects with the mounting direction D 1. When the fastener member 10 is mounted, the elastically deforming portions 30A, 30B deform elastically, so it can be easily assembled without interference between the guide portions 22A, 22B and the guided portions 12A, 12B. After it is mounted, the fastener member 10 is supported without play by the guide portions 22A, 22B of the support member 20 due to the elastic force generated between the elastically deforming portions 30A, 30B and the receiving portions 40A, 40B.
摘要翻译：本发明的紧固构件，紧固件结构和支撑构件可以减少晃动和噪音，而不会降低组装的容易性。紧固件10包括通过引导部分22A，22B在安装方向D1上引导的引导部分12A，12B。形成在被引导部12A，12B上的弹性变形部30A，30B能够沿与安装方向D1相交的方向弹性变形。当安装紧固件10时，弹性变形部30A，30B弹性变形，易于组装而不受引导部分22A，22B与被引导部分12A，12B之间的干扰。在安装之后，由于弹性变形部分30A，30B和接收部分40A，40B之间产生的弹力，紧固构件10被支撑件20的引导部分22A，22B支撑而不起作用。
