The present disclosure relates to a crash pad for a vehicle and a manufacturing method thereof. In an embodiment, the crash pad for a vehicle includes: a skin layer configured to form an outer surface of a crash pad including an airbag module; a core layer formed on a lower surface of the skin layer; and a foam layer formed between the core layer and the skin layer, wherein the skin layer has a tensile strength of 15 to 120 kgf/cm.sup.2 and an elongation at break of 50 to 700% measured in accordance with JIS K6301 standard, and a bonding strength of 0.25 kgf/cm or more as measured in accordance with ISO 813 standard.

A method including inserting into a mold a first tool having a first surface. The method further includes printing a second tool from a polymer material and inserting the second tool into the first tool. The second tool having a smaller wall thickness than the first tool and including a second surface opposing and in contact with the first surface of the first tool and a third surface formed on an opposite side of the second tool than the second surface.

A fixture for heat pressing process is applied to a hot pressing machine for hot pressing two elastic plastic pieces so as to manufacture an airbag. The two elastic plastic pieces are disposed between the fixture and the hot pressing machine. The fixture includes a first frame, a second frame and a flexible heat blocking layer. The first frame includes two first brackets, which are separated from each other with a first distance. The second frame includes two second brackets, which are separated from each other with a second distance, and located at two ends of the first brackets, respectively. The flexible heat blocking layer is fixed by the first frame and/or the second frame.

An inflatable airbag without a heat-resisting layer and its manufacturing method is provided, the inflatable airbag comprises two cavity films, wherein the boundaries of the two cavity films are glued together; the inflatable airbag further includes two valve films which are arranged between the two cavity films; first heat-seal lines are arranged at top ends of the valve films; the valve films and the adjacent cavity films are glued through the first heat-seal lines; the inflatable airbag further includes second heat-seal lines, wherein the second heat-seal lines include disconnected areas and heat-pressing areas which are arranged alternately; in the heat-pressing areas of the second heat-seal lines, the two valve films and two cavity films are glued together; an inflation channel is formed by portions of the two cavity films above the second heat-seal lines; a bag body is formed by portions of the two cavity films below the second heat-seal lines.

A method for making a polyamide composition, in particular for molding, prepared by mixing a polyamide material, a powder made from airbag scraps, and optionally reinforcing fillers is described. Also described, is a method for recycling used airbags.

A method for manufacturing an air bag includes forming a bag portion surrounded by a welded portion extending in an annular shape by pressing at least one welding mold against two sheet materials arranged to be stacked from a stacking direction of the sheet materials. The welding mold is pressed against the sheet materials to form the welded portion including a welding bead portion protruding to an inside of the bag portion between the sheet materials. A pressing surface of the welding mold against the sheet materials is provided with a slope portion facing in the stacking direction of the sheet materials and in a direction of the inside of the bag portion at a position further on an outside of the bag portion than a position at which the welding bead portion is formed.

The invention describes an igniter support (22) for an igniter unit (20) of a gas generator (10), comprising a first holder element (30) made from a first material and a second holder element (32) made from a second material different from the first material. Both holder elements (30, 32) can be positively coupled to each other. Further, a subassembly (16), a gas generator (10) and a method for manufacturing a gas generator (10) are described.
