Abstract

A generally flexible pressure sensing mat for a vehicle seat includes a first carrier foil and a second carrier foil arranged at a certain distance from each other by means of a spacer. The mat includes a plurality of cells, each cell being defined by a respective opening of the spacer. In each cell, at least two electrodes are arranged between the first and second carrier foils and, in response to pressure acting on the pressure sensing mat at a cell, the first and second carrier foils are pressed together against the reaction force of the carrier foils thereby causing variation of an electrical resistance between the at least two electrodes of the cell. The pressure sensing mat includes at least one rigidifying element, the least one rigidifying element being associated to an individual cell for locally reducing flexibility of the pressure sensing mat at the individual cell.
