A manufacturing method of a seat structure member includes forming a protrusion that protrudes inward on an inside surface of a portion that forms a foaming chamber for a seat pad, on one die and another die that form the foaming chamber. Applying, to a cover, a region that will not be integrated with the seat pad when the seat pad is foam molded, at a location on the cover that corresponds to a location of the protrusion when placing the cover on the inside surface of the foaming chamber. The method further includes arranging the cover following a shape of the protrusion and foam molding the seat pad and forming a space of a recessed portion between the seat pad and the cover, by releasing the one die and the other die after foam molding the seat pad.

1. A manufacturing method of a seat structure member, comprising: forming a protrusion that protrudes inward on an inside surface of a portion that formsa foaming chamber for a seat pad, on one die and another die that form the foaming chamber, the protrusion is formed at a position corresponding to a front surface of the seat pad;applying, to a cover, a region that will not be integrated with the seat pad when the seat pad is foam molded, at a location on the cover that corresponds to a location of the protrusion when placing the cover on the inside surface of the foaming chamber;arranging the cover following a shape of the protrusion and foam molding the seat pad;integrating the cover with the seat pad at portions other than the region applied to the cover by making a foam material that defines the foam molded seat penetrate a back surface member of the cover, andforming a space of a recessed portion between the seat pad and the cover, by releasing the one die and the other die after foam molding the seat pad. 2. The manufacturing method of the seat structure member according to claim 1, further comprising: providing the recessed portion formed on the surface of the seat pad at a location other than at a contact surface that is contacted by an occupant when the occupant is seated. 3. The manufacturing method of the seat structure member according to claim 1, further comprising: providing the recessed portion formed on the surface of the seat pad at a position corresponding to an end edge of a shield arranged on an outside surface of a seat. 4. The manufacturing method of the seat structure member according to claim 1, further comprising: providing the seat pad in a seat cushion; andforming the recessed portion on a joining portion of the seat cushion, which joins with a seat back at a rear portion of the seat cushion. 5. A manufacturing method of a seat structure member, comprising: forming a protrusion that protrudes inward on an inside surface of a portion that formsa foaming chamber for a seat pad, on one die and another die that form the foaming chamber;applying, to a cover, a region that will not be integrated with the seat pad when the seat pad is foam molded, at a location on the cover that corresponds to a location of the protrusion when placing the cover on the inside surface of the foaming chamber;arranging the cover following a shape of the protrusion and foam molding the seat pad;forming a space of a recessed portion between the seat pad and the cover, by releasing the one die and the other die after foam molding the seat pad,providing a film through which foam material is unable to pass; andarranging the film between the seat pad and the seat cover to avoid integrated molding of the seat pad and the cover. 6. A manufacturing method of a seat structure member, comprising: forming a protrusion that protrudes inward on an inside surface of a portion that formsa foaming chamber for a seat pad, on one die and another die that form the foaming chamber;applying, to a cover, a region that will not be integrated with the seat pad when the seat pad is foam molded, at a location on the cover that corresponds to a location of the protrusion when placing the cover on the inside surface of the foaming chamber;arranging the cover following a shape of the protrusion and subsequently foam molding the seat pad; and forming a space of a recessed portion between the seat pad and the cover, by releasing the one die and the other die after foam molding the seat pad.
