To manufacture a soundproof sheet included in a vehicle interior material at lower cost.SOLUTION: A manufacturing method for a door trim 10 comprising a trim body part 11 and a soundproof sheet 40 comprises: a sheet forming process in which a soundproof sheet member 30 is cut to form the soundproof sheet 40 with a slit 31; a sheet deformation process which is executed after the sheet forming process, and in which a second sheet part 52 of two parts of the soundproof sheets 40 separated by the slit 31 is rotated around a portion of a marginal part of the slit 31 in the soundproof sheet 40, which corresponds to another end part 31B along in a plane direction of the soundproof sheet 40 to a side apart from a part 51B of a first sheet part 51, thereby deforming the soundproof sheet 40; and a sheet fitting process which is executed after the sheet deformation process, and in which the soundproof sheet 40 in a state of being deformed in the sheet deformation process is fitted to a rear face 11B of the trim body part 11.SELECTED DRAWING: Figure 7
【課題】乗物用内装材が備える防音シートをより低いコストで製造する。【解決手段】トリム本体部11と、防音シート40と、を備えるドアトリム10の製造方法であって、防音性を有するシート部材30を切断することで、スリット31を有する防音シート40を成形するシート成形工程と、シート成形工程の後に実行され、防音シート40においてスリット31によって分けられた2つの部分のうち第2シート部52を、防音シート40におけるスリット31の縁部のうち、他端部31Bに対応する箇所を回転中心として、防音シート40の平面方向に沿って第1シート部51の一部51Bから遠ざかる側に回転させることで防音シート40を変形させるシート変形工程と、シート変形工程の後に実行され、シート変形工程において変形された状態の防音シート40をトリム本体部11の裏面11Bに取り付けるシート取付工程と、を備える。【選択図】図7
