ABSTRACT:
The invention relates to a heating conductor connection between electrically heated seat and backrest surfaces separated by a bracing trough provided in the padding core. Beneath the bracing trough a bracing wire is bonded in the padding core and a connecting seam of the covering materials is located in the bracing trough. A further bracing wire which is disposed in an apron formed by an insert loop is provided, the two bracing wires being connected via clamping clips.
The heated separate surfaces are formed by the heating conductor connections crossing through the bracing trough. These connections take up the mechanical stresses by tension, compression and bending without being endangered.
According to the present invention, connecting webs (4.0) of copper strip (4.1), are provided between the heated surfaces (2 and 3) and the copper strip (4.1) consists of woven or knitted material. The connecting heating conductor section (4.2) is laid in meander or wave form, bearing on the copper strip (4.1) thus formed.
A further embodiment provides that the connecting web (4.0) consists of a two-layer copper strip (4.1) and the heating conductor (4.2) is led in meanders and is freely movable between the two layers.
