Abstract:
The invention relates to a method of producing a vehicle interior lining, especially a dashboard having a carrier part and, attached to the carrier part, a gas bag module containing a gas bag carrier and a gas bag that has a folded package section. The gas bag, together with its package section, is placed into a gas bag receptacle that is formed on the gas bag carrier and that has an outlet opening for the gas bag. The outlet opening is at least partially closed in the area of the package section by a rigid part. An outside surface of the carrier part is foam-encapsulated with a plastic layer in a state in which the gas bag module is connected to the carrier part. Moreover, the invention relates to a vehicle interior lining.
Abstract:
A filtering device for a spinning head for producing plastic threads. The spinning head has a housing in which the plastic melt flows through a filter element under pressure before exiting the spinnerets. The filter element is provided with a filtering material that is subjected to an axial contact pressure through a distributor device, according to the degree of pressure of the melt. This contact pressure acts upon the sealing edges of the filter element to close the sealing gaps. The special geometrical configuration of the filter element and/or its elasticity guarantee advantageous filtering in terms of energy. The filtering system is resistant to pressure and provides good, permanent sealing.
Abstract:
An assembly consists of a first component and of a second component. The first component is provided with at least one opening and with at least one holding projection which is associated with the opening The second component consists of sheet metal and is provided with at least one holding tongue which has a cross-piece and a head. The cross-piece extends through the opening in the first component and is bent around such that the head lies against the side of the holding projection facing away from the opening.
Abstract:
A gas bag for a vehicle occupant restraint system includes a wall, an inflation port configured therein, a deflection part arranged between the inflation port and a portion of the gas bag wall arranged opposite the inflation port, and a counterpiece which is arranged between the deflection part on the one hand and the inflation port as well as a portion of the gas bag wall surrounding the inflation port on the other hand. The deflection part and the counterpiece are stitched to each other such that a prechamber is formed which communicates with the interior of the gas bag by overflow ports formed between the deflection part and the counterpiece.
Abstract:
A method of folding a side impact gas bag comprises the following steps: First, the gas bag is spread out on a base. Then, the rim of the inflation opening of the gas bag is fixed. Thereafter, a plate is arranged at a predetermined distance from the base and parallel thereto, so that the gas bag lies between the base and the plate. Then, the gas bag is inflated between the base and the plate. Finally, the wall of the gas bag is pushed together from the outside inwards, whereby a portion of the wall of the gas bag is turned into its interior.
Abstract:
A method for functionally checking a vacuum switch of a traction inverter having a grid-side four-quadrant chopper and a load-side pulse inverter electrically connected in parallel on the DC side by a DC intermediate circuit. The AC side of the chopper is connected to a secondary winding of a traction transformer, with the primary winding of the traction transformer connectable to an AC grid voltage by a vacuum switch. When the vacuum switch is open, the chopper is actuated precisely when the AC grid voltage is temporally located relative to the chopper input voltage, such that the amplitude of a voltage difference between the AC grid voltage and the chopper input voltage corresponds to a predetermined test voltage. It is then checked whether current flows from the AC supply grid to the chopper. The functionality of the vacuum switch can thus be checked at any time without a test device.

Abstract:
A filter device includes a filter housing (10), a filter inlet (12), a filter outlet (14), and a filter element (16). The filter element divides a filter area (18) into two partial areas (20, 22). One partial filter areas is conical in form with the cross-section of that partial area (20) being tapered from the filter inlet (12) to the filter outlet (14). The partial areas are separated from each other by the filter element. This arrangement results in an optimum residence time distribution inside the filter device at a uniform flow rate, which is particularly useful for highly viscous fluids such as polymer melts or similar.
Abstract:
A gas bag for a vehicle occupant restraint system comprises an inflation opening, a fabric piece arranged inside the gas bag opposite the inflation opening and forming an outflow opening for compressed gas which flows through the inflation opening into the gas bag, and at least one tether which is likewise arranged inside the gas bag. The tether is arranged such that the compressed gas flowing out through the outflow opening from a volume surrounded by the fabric piece, substantially does not flow against the tether.
Abstract:
A passenger side gas bag comprises an envelope part and two lateral parts connected therewith. The envelope part and the two lateral parts are formed from an integral blank (10) of flat textile fabric. The blank comprises an elongated middle section (12), corresponding to the envelope part, and two flaps (14a, 14b) corresponding to the lateral parts and joined to its middle portion. Each flap is sewn along its edge to the adjacent longitudinal edge of the middle section (12).
