Abstract: Disclosed is a motor vehicle twin-tube damper comprising: a tube filled with a working liquid, a piston assembly disposed slidably inside the tube divides the tube into a rebound chamber and a compression chamber. A compensation chamber is located outside of the tube. A base valve assembly including a rebound valve assembly and a compression valve assembly controls the flow of the working liquid between the compensation chamber and the compression chamber. The rebound valve assembly includes a number of rebound flow channels covered by a main deflective disc. To suppress vibrations generated by the deflective disc due to pressure fluctuations occurring during rapid changes of the damper stroke direction, the rebound valve assembly includes an additional deflective disc disposed over the main deflective disc and separated from it by an annular gap with a thickness (G) that is less than the thickness of the main deflective disc.

Abstract: A twin-tube hydraulic damper assembly includes a main tube having an internal radius extending along a center axis between a first end and a second end. An external tube is disposed on the center axis extending about the main tube. A base valve attached to the second end for controlling the flow of the working liquid during the compression stroke and the rebound stroke. A rebound valve of at least one rebound deflective disc having a thickness is disposed in the compression chamber and adjacent to the body. The rebound deflective disc has an external circumferential surface spaced from the main tube defining an annular damping gap extending about the center axis and having a radial width whereby a ratio of said radial width of the annular damping gap to the internal radius is less than 10%.

Abstract: The invention relates to a headrest (10), particularly for a motor vehicle seat. At least on element is provided that can be displaced relative to a retaining device (12) of the headrest (10). The at least one element can be displaced, in part and/or in total, about at least one horizontal rotation axis and/or at least one vertical rotation axis and can be locked in selectable displaced positions.

Abstract: Disclosed is a headrest for a vehicle seat, comprising a cushion support (P) that is retained at the top of a backrest by means of at least one support bar (13) and surrounds a hollow space by means of housing walls (16, 18). The forward housing wall (16) of the cushion support (P), which forms a main surface, accommodates a head resting zone that is provided with two swing-lockable swiveling wings (F). Said swiveling wings (F) form a support structure for a cushion and are hinged in the central area (M) of the head resting zone so as to be pivotable about at least one vertical swiveling axis (20). The swing-lockable swiveling wings (F) are formed by the sections of the forward housing wall (18), which immediately border the hollow space of the cushion support (P).

Abstract: A pressure-jet oil burner nozzle includes a body having a threaded rear connecting socket to connect the nozzle to a pressure oil conduit. The nozzle includes a front nozzle tip connected to the body and having an oil discharge passage, and an insert having a front end provided with grooves disposed in the nozzle body with the front end disposed close to the side of the nozzle tip facing the interior of the body whereby the grooves, together with the inner side of the nozzle tip, define flow passages leading from the nozzle body to the oil discharge passage in the tip.
