Electric heating apparatus, particularly for a vehicle

摘要

The electric heater unit, in particular for a motor vehicle, comprises a frame (2) with heating elements (7) in the form of electrically conductive plastic layers with a positive temperature coefficient (PTC) between contact strips, alternatively positioned secondary areal elements (8), and at least one spring (9). The purpose of this electrically conductive spring is to press (7) and (8) to one another.
