Abstract: A powder composite core is to be particularly dense and strong while being produced from soft magnetic alloys. In particular, the expansion of the heat-treated core is to be avoided. To produce this core, a strip of a soft magnetic alloy is first comminuted to form particles. The particles are mixed with a first binder having a curing temperature T1,cure and a decomposition temperature T1,decompose and a second binder having a curing temperature T2,cure and a decomposition temperature T2,decompose, wherein T1,cure<T2,cure?T1,decompose<T2,decompose. The mix is pressed to produce a magnet core while the first binder is cured. The magnet core is then subjected to a heat treatment accompanied by the curing of the second binder at a heat treatment temperature TAnneal>T2,cure.

Abstract: Disclosed herein is a method for the production of an anisotropic magnetic powder or a magnet produced from said powder, wherein a hydrogenating and dehydrogenating method is applied to the starting material in order to produce the powder. An anisotropic oriented magnetic material, more particularly magnetic scrap metal, is advantageously used as starting material so that the complicated use of a molten mass with isotropic distribution of the c axes of the hard metal crystals is not required. The result is an anisotropic material having a fine grain structure and a crystallographic orientation matching a TMXB phase formed during hydrogenation.

Abstract: A head restraint for a vehicle seat includes a first subsection facing the occupant's head, and is displaceable due to application of a predetermined force. A third subsection includes a central hub portion that supports the second subsection. The second subsection is arranged between the first subsection and a third subsection, and is mounted to the central hub portion of the third section and the first second and third subsections are rotatably displaceable about an axis of rotation that is parallel to the direction of displacement (C). A blocking device includes a toothed portion complimentarily engaged with a spacer device on the third subsection and having a resilient member preventing engagement of the toothed portion by the spacer device when the first subsection is not subjected to the application of the predetermined force, and also controls movement of the first subsection counter to a direction of displacement.

Abstract: In a method for producing a trim article (1), the interspace between a sheet-like decorative material (5) and a carrier (3) is foam-filled. There is provision, during foaming, for the decorative material (5) to be pressed sealingingly onto the interior-side surface of the carrier (3) so as to run around the region to be foam-filled. In this case, the discharge of the air to be displaced during foaming can take place through the foam-tight, but, at least in regions, not gas-tight structure of the carrier (3). For this purpose, the carrier (3) can be gas-sealed in regions by the local compression of an intrinsically gas-permeable unprocessed part before introduction into the foaming die. Also disclosed is a trim article capable of being produced according to the method.
