PROBLEM TO BE SOLVED: To provide a manufacturing method for a cushion member that allows an occupant detection sensor to be stably operated.SOLUTION: The cushion member is used for a vehicular seat configured so that an occupant detection sensor is operated when the occupant is seated so as to detect whether the occupant is present or not and comprises a pad material and a seat material 62 to be arranged on a surface at the opposite side of the occupant side of the pad material. The seat material 62 is a portion which can contact the occupant detection sensor and has: a sensor operation portion 63 that contacts the occupant detection sensor to operate the occupant detection sensor when the occupant is seated; and a plurality of positioning portions 64A, provided around the sensor operation portion 63, which position the seat material 62 relative to a mold. In the manufacturing method for the cushion member, the seat material 62 is set in the mold and a material for the pad material is cast into the mold and then solidified, in a state where a positioning portion 64A is aligned with a mold-side positioning portion 84A of the mold and the sensor operation portion 63 is expanded.SELECTED DRAWING: Figure 12
【課題】乗員検知センサを安定して作動させることができるクッション部材の製造方法を提供する。【解決手段】乗員が座ったときに、乗員検知センサが作動することで乗員の有無を検知するように構成された乗物用シートに用いられ、パッド材と、パッド材の乗員側とは反対側の面に配置されるシート材62とを備え、シート材62が、乗員検知センサに接触可能な部位であって、乗員が座ったときに乗員検知センサに接触して乗員検知センサを作動させるセンサ作動部63と、センサ作動部63の周囲に設けられ、シート材62を型に対して位置決めする複数の位置決め部64Aとを有するクッション部材の製造方法であって、位置決め部64Aを型の型側位置決め部84Aに合わせてセンサ作動部63を張った状態でシート材62を型にセットし、型にパッド材の材料を流し込んで固める。【選択図】図12
