  • Patent number: 6591685
    Abstract: The present invention relates to a pressure sensor comprising a capacitor with a first capacitor pole element (1) and at least one additional capacitor pole element (3) arranged at a distance from one another. In accordance with the invention, at least one capacitor pole element (1, 3) has at least one textured region (31, 31′ and/or 32, 32′) on the surface of its conductive components facing toward the other capacitor pole element (3, 1), and the distance between the two capacitor pole elements (1,3) is different in the textured region (31,31′ and/or 32; 32′) than in an adjacent region (32, 32′ and/or 31, 31′) to the textured region (31; 31′ and/or 32, 32′). The difference between these two different distances can be changed—more particularly, reduced—by deformation of at least one capacitor pole element (1,3) when the capacitor is subjected to pressure.

  • Patent number: 6448789
    Abstract: The present invention concerns a detector for detecting seat occupancy with at least two flat electrodes and a separating medium that separates the two electrodes from each other. The invention provides that the separating medium (3) has at least one spacing zone (4) and one deformation zone (5), which has a greater compressibility than the spacing zone (4).
