Abstract
A two-dimensional heating element, especially for seat heaters in the motor vehicle sector, having a textile base material and contact conductors and heating conductors which are electrically conductive and touch one another. The contact conductors delimit heating areas. The heating conductors are laid effectively in the direction of stitch wales and orthogonal to the stitch wales in such a way that there are at least two zones functioning at least as a main heating area and at least as a secondary heating area with different heating capacities.
