Embodiment Construction
[0033] figure 1 A plan view of a vehicle seat 10 equipped with an embodiment of a seat occupancy detection device 12 is schematically shown. The seat occupancy detection device 12 generally includes a sensing layer 14 associated with a seat seating surface 16 . A homogeneous sensing layer 14 has at least one electrical property, such as electrical resistance, that depends on the compressive deformation of the sensing layer 14 .
[0034] At the edges defining the periphery of the sensing area of the sensing layer, the sensing layer 14 is equipped with a plurality of electrodes 18 . The electrodes 18 are arranged equidistantly along the longitudinal edges of the sensing layer 14 and along the transverse edges.
[0035] It should be noted that in the illustrated embodiment the electrodes 18 are distributed along the entire length of each edge. However, it should be understood that other embodiments are possible in which no electrodes are arranged in the corners of the sensing ...
