Publication number: 20230392724Abstract: A clamp has a structure including a band portion wrapping a circular member, such as a hose, a washer portion, a nut portion, and a connection portion and support portions that prevent the band portion from being deformed when a bolt is tightened, these portions being integrally formed with each other into a single portion. Therefore, reduction in the separate portions causes cost reduction, weight reduction, and reduction in risk of loss of the separate portions, and the performance problem in that the clamp rotates when the tightening work is performed by rotation of the bolt is improved.Type: ApplicationFiled: October 24, 2022Publication date: December 7, 2023Applicants: Hyundai Motor Company, Kia Corporation, DONG-A METAL CO.,LTD.Inventors: Yong Seok JANG, Yong Gyo SEO, Han Il JUNG

Patent number: 10865748Abstract: An air cleaner is provided. The air cleaner includes an air cleaner body and air cleaner cover that are coupled to each other to form an internal space for mounting a filter and that are clamped and separated through a cover clamp. The filter purifies air that is introduced through a duct inlet into air which is to be discharged through a hose outlet. A filter fixer is formed in the internal space to seat the filter and forms a filter holding force to block swaying of the filter. Additionally, a filter adapter is mounted into or detached from the internal space and is inserted into the internal space to form a filter fixing force for fixing the filter.Type: GrantFiled: May 25, 2018Date of Patent: December 15, 2020Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Seong-Youn Kwak, Won-Seop Choi, Ju-Ho Han, Yong-Gyo Seo, Sung-Hyuk Yoon
