Heating and ventilation inlay for a vehicle seat
First Claim
1. A heating and ventilation inlay for a vehicle seat comprising:
- an inlay adapted to be placed in a complementary recess in a seat cushion or backrest of the vehicle seat and disposed underneath a seat trim, wherein the heating and ventilation inlay comprises;
an arrangement of layers including an air permeable heating mat having a heating conductor arranged on the heating mat, andan air permeable layer of spacer material positioned underneath the heating mat that is connected to a fan or a suction fan to transport air conveyed by the fan or the suction fan through the heating and ventilation inlay,wherein the heating mat and the layer of spacer material are connected to each other to form a composite unitary component, the heating mat and the layer of spacer material being connected by a plurality of rivets distributed over an area of the heating and ventilation inlay and that pierce through the heating mat and the spacer material layer, andan enforcement layer disposed between at least two of the plurality of rivets, the enforcement layer being coupled in abutment with a surface of the heating mat by the at least two rivets.

Abstract
The present invention is directed to a heating and ventilation inlay for a vehicle seat that is adapted to be placed in a recess in a seat cushion or backrest of the vehicle seat underneath a seat trim. The heating and ventilation inlay comprises an arrangement of layers including an air permeable heating mat having a heating conductor running on the heating mat. Underneath the heating mat an air permeable layer of spacer material is connectable to a fan or suction fan for transporting air through the heating and ventilation inlay. The heating mat and the layer of spacer material are connected to each other and form a composite that can be handled as a unitary component, by a plurality of rivets which are distributed over the area of the heating and ventilation inlay. The rivets are pierced through the heating mat and the spacer material layer.
