Abstract: A self-standing sandwich structure includes at least one capacitive sensor member and/or at least one heater member for automotive vehicle application. The self-standing sandwich structure includes an upper protective layer that is attached, for manufacturing and storage purposes, to a carrier film member of sufficiently low surface energy for enabling separating the carrier film member and the upper protective layer in a non-destructive manner, a lower protective layer, a bottom adhesive layer that is attached to the lower protective layer, and at least an upper electrically conductive layer arranged between the upper protective layer and the lower protective layer.

Abstract: A flexible electric heating device includes a planar flexible carrier foil, at least two electrically conductive bus lines attached to a surface of the carrier foil, and at least one electric heating member, including first and second electrically conductive electrodes, electrically connected to one of the bus lines. Each electrode has at least one curved edge, wherein the curved edges are located at a distance and are facing each other. The heating member further includes a resistive heater layer, at least partially overlapping the curved edges of the electrodes to form a resistive connecting region. The curved edges are arranged such that locations of the resistive connecting region are facing the first electrode or the second electrode in directions parallel to at least three mutually orthogonal directions that lie in the carrier foil, wherein one of the orthogonal directions is aligned parallel to an edge of the carrier foil.

Abstract: An electric heating member, in particular for automotive application, includes an electrically conductive, flat-shaped textile member of uniform thickness and a layer of flexible, polymeric plastic material that is adhesively bonded to a surface of the textile member. The electrically conductive textile member is formed by at least two electrically conductive textile member parts that are arranged side by side and are electrically separated. At least one of the at least two textile member parts is electrically connected to electric terminals that are connectable to an electric heater power supply unit. The electric heating member is particularly intended to be used for heating a vehicle steering wheel.
