Publication number: 20250091493Abstract: A rear seat apparatus for a vehicle includes a back frame and a cushion frame. The back frame is not interlocked with the cushion frame and is individually rotated in the forward-and-rearward direction independently of the cushion frame. The cushion frame is not interlocked with the back frame and individually slides in the forward-and-rearward direction independently of the back frame. A front seating state and a rear seating state of a passenger are implemented through individual sliding movement of the cushion frame in the forward-and-rearward direction.Type: ApplicationFiled: January 18, 2024Publication date: March 20, 2025Inventors: Mu Young Kim, Hee Dong Choi, Soo Hyun Moon, Wan Su Park, Gil Ju Kim, Seok Ju Gim, Kyoung Su Oh, Jae Hong Bae, Dong Hyeon Kim, Yong Tak Han, Sung Wook Lee, Yong Sun Oh, Kyu Hee Lee
