PROBLEM TO BE SOLVED: To save a weight of a vehicle seat as much as possible as well as to reduce cost of manufacturing and equipment by using FRP as a material of completely all main members for front and rear legs.SOLUTION: A rear leg 3 is constituted of: a downward inclined leg part 3A made of a composite material directed to a rear fixing part 1R inclined rear-downward from a front lateral member 6; and an upward inclined leg part 3B extending to rearward, to a rear lateral member 7 from a substantially intermediate part of the downward inclined leg part 3A. The front and rear legs have an I-shaped structure in which a web part 16 for receiving shear load, arranged on a YZ surface, and laminate configuration press-formed resin bodies 18 reinforced by continuous carbon fibers are arranged for the whole width or a part of an opposite web part side on flange parts 17 for receiving tension/compression axial forces and reinforcing rigidity. A leg structure formation method includes a step for injecting a compound resin to form an injection molding compound resin body 19 for a remaining area of the flange part 17 and the web part 16.SELECTED DRAWING: Figure 1
【課題】前脚、後脚おける主部材の完全なFRP化により座席の可及的な軽量化を図り、かつ製造や設備の低廉化を実現する。【解決手段】後脚3は、前方横材6から後方下り傾斜し後方定着部位1Rに向かう複合材製下り斜脚部3Aと、その下り斜脚部3Aの略中間部位から後方に向けて後方横材7に向けて延びる上り斜脚部3Bとで形成される。前後の脚はせん断荷重を負担するウェブ部16をYZ面内に配したI形構造であって、引張・圧縮軸力を負担し剛性を増強させるフランジ部17における反ウェブ部側の全幅もしくは一部に連続炭素繊維補強のラミネート構成プレス成形樹脂体18が配され、フランジ部17における残余域およびウェブ部16は注入成形のコンパウンド樹脂体19とすべく、コンパウンド樹脂が注入されるという手順を採られる。【選択図】図1
