Abstract: A chassis for a passenger car includes two main longitudinal chassis beams which are connected to one another via a bumper cross member. A support arrangement extends between the two beams and is supported on a central tunnel. The support arrangement forms a load path in an event of a collision-related force being applied to the passenger car where above and/or below the support arrangement an installation space region is provided for accommodating a component or unit in need of protection. The support arrangement includes a strut which extends in a region of a center of the passenger car between the two beams and which forms a protective device which transmits impact forces forwards to the central tunnel. The strut has a first longitudinal section that is deformable in a targeted energy-absorbing manner and a second longitudinal section which functions as a rigid beam.

Abstract: A method is for producing a grid-like beam collimator. In an embodiment, the method includes printing a suspension, including a binder and metal particles, in several stacked layers to build a layer stack with a grid structure including a number of crossing webs, and removing the binder from the layer stack. In an embodiment, the printing includes applying a curable liquid stiffening material at least on a surface of the grid structure, and curing the curable liquid stiffening material after the applying.

Abstract: In the heating device, PTC heating elements arranged between current rails lying opposite each other are used, which are fed with supply current from a control electronics unit via the current rails. Metallic heating rib structures are respectively coupled to one of the current rails via an electrically insulating but thermally conducting coupling layer. The air to be heated flows through the heating rib structures which have an undulating shape. The metallic heating rib structures are electrically connected to vehicle ground and thus form a shield that eliminates emissions of electromagnetic interfering radiation without impeding the flow of air.
