Abstract

An electric heating member (10), in particular for automotive application, comprises an electrically conductive, flat-shaped textile member (12) of uniform thickness (t) and a layer of flexible, polymeric plastic material (26) that is adhesively bonded to a surface of the textile member (12). The electrically conductive textile member (12) is formed by at least two electrically conductive textile member parts (22) that are arranged side by side and are electrically separated. At least one of the at least two textile member parts (22) is electrically connected to electric terminals that are connectable to an electric heater power supply unit (50). The electric heating member (10) is particularly intended to be used for heating a vehicle steering wheel (46).

Description

technical field [0001] The invention relates to an electric heating element, in particular for motor vehicle applications, and to a method of manufacturing such an electric heating element. Background technique [0002] Electric heating devices employing one or more electric heating members are widely used in the motor vehicle industry to provide passenger comfort, for example by heating the general vehicle compartment and / or passenger seats and / or armrests and / or panels. Electric heaters are also used in vehicle steering wheels for immediate heating after starting the vehicle's engine in cold ambient conditions. [0003] It is considered a requirement for such electric heating means that they should be unnoticed by the vehicle user if not in operation. Another requirement is to heat up as uniformly as possible during operation, for example in the range of a few degrees Celsius, to avoid hot spots that could be noticed by the vehicle user and also to avoid the generation of...
