Abstract: A decorative layer for an air bag covering, especially for use in motor vehicles, is provided with a local initiating area in the decorative layer, the tear for tearing through the decorative layer when the air bag is deployed being initiated in this area. The air bag covering, includes a shaped part with predetermined break-lines and a decorative layer applied to the shaped part. At least one locally limited initiating area is provided in the decorative layer, the tear for tearing through the decorative layer when the air bag is deployed being initiated along the predetermined break-lines of the shaped part, in this area.

Abstract: A method of producing an injection molded part in which an insert is disposed within a mold cavity and extrusion coated with a plastic material fed via injection cylinder by layering at least one hard component and at least one soft component of a plastic material within the injection cylinder and then successively feeding the hard component followed by the soft component out of the injection cylinder into the mold cavity to extrusion coat the insert.

Abstract: An interior fixture or fitting part for vehicles, particularly motor vehicles, comprising a rigid molded support part (2), a layer of knitted spacer fabric (3) or formed fabric disposed on a surface of the molded support part (2) and a layer of natural leather (4) on the knitted spacer fabric (3) or formed fabric as well as a first adhesive layer (5) between molded support part (2) and knitted spacer fabric (3) or formed fabric and a second adhesive layer (6) between knitted spacer fabric (3) or formed fabric and natural-leather layer (4). An associated production method is also proposed.

Abstract: A process is disclosed for producing interior trims for transport means, in particular motor vehicles, that consist of a bearing dimensionally stable part and of a decorative part that forms the visible side of the interior trim. The bearing, dimensionally stable part is made of plastic materials stiffened by reinforcing inserts. In order to considerably improve the process, the plastic materials consist of natural or recycled polyols and isocyanates and a material made of natural fibers is used for the reinforcing inserts. The material made of natural fibres is laid into a heatable (foaming) mold whose shape corresponds to that of the interior trim to be produced, the reactive, foamable polyurethane mixture is injected into the mold at a dosing pressure from 100 to 300 bars, then foamed and hardened in the mold at a reaction pressure form 3 to 300 bars.

Abstract: The invention relates to a process of and an apparatus for injection molding hollow-blown plastic bodies in which a mold cavity formed by a tool and consisting of at least one main mold cavity and one side mold cavity is filled with a pressurized flowable plastic melt and, after the setting in of the hardening of the plastic melt at the walls of the mold cavity, a pressurized fluid is introduced into the main mold cavity, and, with this, the flowable core of the plastic melt is forced out of this main mold cavity, and subsequently, a pressurized fluid is introduced into the side mold cavity by means of which the flowable core of the plastic melt is forced out of the side mold cavity into the main mold cavity, where the material still capable of flowing is deposited on the already hardened walls in the main mold cavity.

Abstract: The invention relates to a process of and an apparatus for injection molding hollow-blown plastic bodies in which a mold cavity formed by a tool and consisting of at least one main mold cavity and at least one side mold cavity connected with this is filled with a pressurized flowable plastic melt and, simultaneously or after the setting in of the hardening of the walls in the main mold cavity, a pressurized fluid is introduced into the main mold cavity, as a result of which the flowable core in the main molded cavity is displaced while forming a flow front and, as soon as the flow front has reached the point of connection to the side mold cavity, a pressurized fluid is additionally introduced into the side mold cavity at the side opposite the point of connection such that the molten core in the side mold cavity is forced out together with the molten core in the main mold cavity.

Abstract: An interior furnishing part for use in motor vehicles has a covering material sheet forming the exterior or facing surface of the furnishing part backed by a support part with a padding material between the covering material and the support part. Initially, the material sheet is unshaped and is shaped in a mold. During molding, the material sheet is provided with a recess or rib in the exterior or facing surface. After the molding operation, a decorative or attachment seam is sewn in the exterior surface of the furnishing part with the sewing machine guided by the recess or rib. The seam extends at least partly through the interior furnishing part. A foamable material can be used as the padding material.

Abstract: A steering wheel with a steering wheel rim which is covered by a cover of leather or a leather-like material. The cover is made of a single-piece material blank whose two longitudinal edges are connected to each other along the steering wheel rim. The connection of the two longitudinal edges is located on the underside of the steering wheel at a distance from the inner circumference of the steering wheel rim.
