To provide a bead foam molding member that is a cushioning member inserted to an opposite side to a seating surface of a resin foam molding that is a cushioning material of a vehicular sheet, which suppresses deformation in molding.SOLUTION: A bead foam molding member 20 is integrated in a layer form to an opposite side to a seating surface of a cushion pad 1 that is a cushioning material of a vehicular sheet. When the bead foam molding member 20 is viewed from a direction approximately vertical to the seating surface, a frame-shaped frame 23 is inserted and formed on the outer peripheral edge part of the bead foam molding member 20. In a region surrounded by the frame 23 of the bead foam molding member 20, a central horizontal through hole 25, a left and right horizontal through hole 26, a central vertical through hole 27 and a left and right vertical through hole 28 that are slit-like through holes penetrating in a thickness direction are provided.SELECTED DRAWING: Figure 3
【課題】乗物シートのクッション材である樹脂発泡成形体の着座面と反対側にインサートされるクッション部材であるビーズ発泡成形部材において、成形時の変形を抑制したビーズ発泡成形部材を提供する。【解決手段】乗物シートのクッション材であるクッションパッド1の着座面と反対側に層状に一体化されるビーズ発泡成形部材20である。ビーズ発泡成形部材20を着座面に対し略垂直な方向から見たとき、ビーズ発泡成形部材20の外周縁部には枠状のフレーム23がインサートされて形成されている。ビーズ発泡成形部材20のフレーム23に囲まれる領域には厚み方向に貫通するスリット状の貫通孔である中央横貫通孔25、左右横貫通孔26、中央縦貫通孔27、左右縦貫通孔28が設けられている。【選択図】図3
