Abstract: A webbing strap device of adjustable length include an adjustment strap anchor, an adjustment loop anchor with an adjustment loop eyelet, a ladder-shaped sliding body with a first frame crossbar, a second frame crossbar spaced from the first frame crossbar and at least two intermediate crossbars arranged between the first frame crossbar and the second frame crossbar, and a webbing strap attached to the first frame crossbar and to the adjustment strap anchor. The webbing strap extends through the slider between the at least two intermediate crossbars to form an adjustment loop. In the region of the adjustment loop, the webbing strap extends through the adjustment loop eyelet.

Abstract: A method for manufacturing a filter medium comprising at least two filter plies according to which at least a first filter ply has a plurality of thermoplastically deformable fibres, by means of which the at least two filter plies are joined to each other in some areas. The method comprises forming, by means of at least two rolls of a pressing tool, at least one additional joining region configured in a web-like manner in the at least two filter plies in which the at least two filter plies are joined to each other.

Abstract: A device for adjusting a motor vehicle valve train includes at least one camshaft with at least four cam elements arranged in an axially displaceable manner. In each case two of the cam elements that are adjacently situated are formed as a cam element group to be switched together.

Abstract: A filter material for an air filter may include a substrate layer on an inflow side and a fine-fiber layer on an outflow side relative to a flow direction. The filter material may include a connection region arranged between the substrate layer and the fine-fiber layer. The substrate layer, connection region and fine-fiber layer may include pores having an aggregate degressive pore size with respect to the flow direction. A combined thickness of the substrate layer, connection region and fine-fiber layer may be at least 0.35 mm. The substrate layer may include a cellulose material and have an impregnation of resin disposed along the inflow side. The resin may amount to approximately 22% by mass of the substrate layer.

Abstract: A filter element for a filter device may include a filter body having at least one filter material for filtering a fluid. The filter body may have a first side and a second side facing away from the first side. The filter body may include a plurality of body pores. The filter body may have a porosity that is lower on the first side than on the second side. A nano-fiber layer may be disposed at least partially on the first side.

Abstract: In a motor vehicle valve train adjustment device comprising at least one camshaft with at least two axially displaceable cam elements wherein at least one cam element has a cam track with a valve lift and a cam track with zero valve lift for a deactivation of at least one cylinder, and at least one other cam element of the at least two axially displaceable cam elements has a cam track with a first valve lift and a cam track with a second valve lift by which a cylinder which remains fueled during a partial cylinder deactivation is adapted to the at least one cylinder deactivation by special valve lift characteristics.
