Patent number: 10758060Abstract: A cover-material fastening clip includes a locking portion having a guide piece and a hook which includes an extension portion and a distal end portion. The guide piece extends includes a bent portion bent and extended toward the distal end portion. An insertion opening having a predetermined gap and allowing a wire to be inserted therethrough is positioned between the bent portion and the distal end portion. A distal end portion of the guide piece extending from the bent portion is an elastic piece portion being elastically deformed to be spaced from the distal end portion and to widen the insertion opening. In a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow a distal end of the elastic piece portion to be positioned therein.Type: GrantFiled: April 27, 2016Date of Patent: September 1, 2020Assignee: YKK CorporationInventors: Genta Matsumura, Shinsuke Saiga, Yoshitomo Iyoda, Takefumi Adachi

Patent number: 10618800Abstract: There is provided a skin-material fixing clip for connecting a skin material with a cushion material and provided with a locking section and a hook. The hook is provided with an extension portion extending downward from the locking section and a claw-shaped portion extending laterally from a distal end of the extension portion. The locking section is provided with a wire guide piece. A groove portion surrounded by the claw-shaped portion and the extension portion defines a wire holding space. Parts of the wire guide piece and the claw-shaped portion facing the wire insertion opening defines guide surfaces. The distal end portion of the wire guide piece and the distal end portion of the claw-shaped portion are provided to be spaced from each other along a direction parallel to an extending direction of the groove portion.Type: GrantFiled: May 1, 2015Date of Patent: April 14, 2020Assignee: YKK CorporationInventors: Genta Matsumura, Tomonari Yoshida, Ryuichi Murasaki, Yoshitomo Iyoda, Yuka Makino, Tsutomu Yamada
