<P>PROBLEM TO BE SOLVED: To ensure high elastic supporting force of a front end of a seat cushion in a normal-length state regardless of a structure allowing reduction of the seat surface length of the seat cushion. <P>SOLUTION: The seat cushion 12 is formed by being separated into a rear-part-side sheet cushion body 12-2 including a hip supporting surface 12-2a, and a front end part 12-1 coupled to and held at a front end position of the seat cushion body by a coupling holding means. The front end part 12-1 is formed to have an almost triangular side surface having a front end seat surface 12-1a forming a seat surface front end of the seat cushion by being disposed in succession to the seat surface 12b of the seat cushion body, an opposed surface 12-1b disposed in opposition to a front surface of the seat cushion body when coupled to and held at the front end position of the seat cushion body, and an inclined surface 12-1c connecting together the front end seat surface and the opposed surface by disposing a pad material around a core material and covering the pad material with a cover material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
