Cladding element having a heating layer in a sandwich construction

A structural part in a form of a folding mechanism for an emergency exit of an aircraft, the structural part comprising:

• a metallic frame in a form of an articulated support structure to which holders and connecting tabs for the emergency exit are fastened in a mechanically stable manner;
• a cladding element that is attached to the metallic frame to face an interior space of the aircraft, the cladding element comprising:
• a first cover layer forming a visible side of the cladding element;
• an electrically heating layer extending across at least a sub-face of the first cover layer and serving for generating heat for emission through the first cover layer;
• two intermediate layers that are sandwiched between the electrically heating layer and the first cover layer;
• a further intermediate layer that is positioned on an opposite side of the electrically heating layer from the two intermediate layers, such that the electrically heating layer is sandwiched directly between one of the two intermediate layers and the further intermediate layer;
• at least one core layer disposed such that the electrically heating layer is sandwiched between the at least one core layer and one of the two intermediate layers;
• and
• an electrical conductor that is electrically connected to the electrically heating layer;
• wherein the two intermediate layers are formed from a fiber-composite material;
• wherein a first portion of the electrical conductor is sandwiched directly between the at least one core layer and the further intermediate layer;
• wherein a second portion of the electrical conductor passes through a cutout formed in the further intermediate layer, such that the second portion of the electrical conductor electrically contacts the electrically heating layer;
• and
• wherein the first cover layer, the electrically heating layer, the two intermediate layers, and the at least one core layer are arranged such that the cladding element has a sandwich construction;
• and
• at least one viewing window that penetrates the structural part, including the cladding element, to allow a view from the interior space of the aircraft, through the at least one viewing window, through the structural part.
