Abstract
An apparatus for a heating device for a vehicle comprises a layer stack which, in a stacking direction, has a heating conductor layer, an electrically conductive layer which forms a contact region, wherein a contour in a projection in the stacking direction of the electrically conductive layer is prespecified, in order to prevent a hotspot on the electrically conductive layer, by at least one of a prespecified width of a front side of the electrically conductive layer which faces a central region of the heating conductor layer, a prespecified distance from a joint of the heating conductor layer, and a prespecified curvature of the contour.
