Mould for making a support element for the human body, such as a bicycle saddle or a motorcycle saddle, wherein the mould includes a first component or matrix, which it is provided with a cavity open at the top, and at least one second component or false-male, in which the second component or false-male has a through opening, the cavity of the first component or matrix and the through opening of the second component or false-male determine a cavity, which has a conformation in use matching the conformation and/or the bulk and/o to the outer surface of the support element for the human body or the saddle; method for obtaining the support element for the human body and support element for the human body.

A molded foam is provided in which even when a force in a sliding direction is applied to another member in contact with its surface, the occurrence of a shift in position relative to the other member can effectively be prevented and the occurrence of unusual noise due to rubbing between its surface and the other member can effectively be prevented. The molded foam is formed by heating expandable resin particles filled into a foaming mold. The molded foam has a plurality of first ridges arranged in one direction and a plurality of second ridges arranged in another direction and disposed so as to intersect the first ridges, the first and second ridges being provided on the surface of the molded foam.

A lining element for use in a vehicle in order to cover an airbag includes a dimensionally stable backing layer with a first predetermined breaking region which is delimited from a surrounding region and/or from a second predetermined breaking region by at least one predetermined breaking line, where a plurality of regularly spaced predetermined breaking points are disposed along the predetermined breaking line.

A device for molding a plastic component having at least one undercut is disclosed herein. The device including; a fixed block and a mobile block, the fixed block and the mobile block joining along a joining plane and defining first and second cavities defining a molding cavity to receive the plastic, the molding cavity having a first volume and a main direction of demolding; means of separating the mobile block from the fixed block; at least one mobile insert placed in the fixed block; thrusting means urging the mobile insert toward the mobile block; means for moving the at least one mobile element in a secondary direction not parallel to the main direction of demolding.

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.

A foam molded body production device (20) including a plurality of molds (21); a cavity (23) that is delimited, between the plurality of molds (21), by cavity surfaces (22) of the plurality of molds (21); and a protrusion portion (28) that is formed on the cavity surfaces (22). The protrusion portion (28) is formed from an elastic body. The cavity surfaces (22) are provided with a holding portion (29) that contacts a tip of the protrusion portion (28) when the plurality of molds (21) are closed, and causes the protrusion portion (28) to elastically deform inside the cavity (23).
