Abstract: A cover plate for a gas bag restraining system has a badge bearing an emblem fixed on its front side. The badge has a tubular rivet formed thereon which extends through the cover plate and whose free terminal section is rolled over at the rear side of the cover plate. The rolled over terminal section of the tubular rivet is curved convexly and is directed toward the rear side of the cover plate.

Abstract: The invention relates to a cover for a gas bag of an occupant restraining system in vehicles and more especially to the attachment of such a cover on the instrument panel on the front passenger seat side of a motor vehicle. The cover is characterized in that on the side, which faces the instrument panel (12), of the covering plate (10) at least one tape-like lug (14) is formed, which is trained under a holding yoke (16) secured in the interior of the instrument panel and at its end (18) opposite to the covering plate is so widened that this end is unable to slip past the holding yoke.

Abstract: The process for manufacturing an open pore foam body with three dimensional ceramic network, in particular as a filter for the treatment of hot gases or as a catalyst substrate, has as its starting material a block of open pore plastic foam. This is impregnated at least once with a ceramic suspension, freed of excess ceramic suspension and heated to a temperature below the melting point of the plastic, then finally burnt off at a temperature at which the ceramic sinters together. The plastic foam block of the prescribed outer dimensions is cooled down and machined to produce a Z-flow filter with high precision longitudinal channels.

This is impregnated at least once with a ceramic suspension, freed of excess ceramic suspension and heated to a temperature below the melting point of the plastic, then finally burnt off at a temperature at which the ceramic sinters together. At least one plastic foam layer is impregnated, assembled into a plastic foam block with flow channels between two layers and sintered to form a Z-flow filter.
