    Abstract: The metal (1) and plastic (2) parts of the component are placed in contact with each other and may be held (10) together. A tool (3) for joining both parts is driven through the metal part and either completely or partly through the plastic part. The tool is then retracted leaving a recess or opening in the composite component in which the deformed metal part makes a positive connection. The plastic part is heated above room temperature in the joining area and the joining tool is moved perpendicularly onto the metal surface. Alternatively two non-parallel joining tools may be used. The joining tool is rotated around its own axis, in particular when retracting from the maximum penetration point. The tool may also perform an oscillating, wobbling or spinning movement. The maximum joining tool diameter which penetrates the composite component is twice the thickness of the latter. After removal of the joining tool from the opening an undercut may be formed in the metal using a hammer, punch or further joining tool. Joining tools comprise a tapering mandrel which may have an asymmetric shape. The penetration area of the tool may be shaped either like that of a self-cutting or thread forming screw or a slotted or crossed slot screw driver. An Independent claim is included for a composite part produced by the process.

    Abstract: The invention relates to a vehicle door (1), comprising an inner wall (2) and an outer wall (3), which are firmly connected to each other, at least in parts. The door also comprises a door function module (4), fixed in the region between the inner wall and the outer wall, with at least one outlet (7) in the inner wall. Said door function module (4) bears directly or indirectly in an at least partial manner upon the inner side of the inner wall of the door(2). The invention also relates to a method used to produce said vehicle door.

    Abstract: The seat (1), and especially the backrest (2), has a frame (2) which is wholly contained within a shaped plastics body (3). The plastics material has a module of elasticity of at least 500 MPa, according to ISO 527, using a thermoplastic, especially polyamide, polypropylene, polyethylene, styrene copolymer, polycarbonate, polyester, polyacetal or polyurethane, or their blends with or without filling materials. The seat is produced by blow moulding, injection moulding, heat moulding and/or pressing.
