A capacitive sensor member (130) of a vehicle seat occupant detection and classification device (18) comprises a first electrically conductive antenna member (132) and at least a second electrically conductive antenna member (134) that is adjacently arranged to the first electrically conductive antenna member (132) without any mutual galvanic connection. At least one electrically conductive bridging member (146) is fixedly attached to at least one elastic spacer member (148) that has elastic mechanical properties in a specified direction (54). If a mechanical load (F) is applied to the capacitive sensor member (130) in the specified direction (54) that is equal to or larger than a predetermined value for the mechanical load (F), the at least one electrically conductive bridging member (146) provides at least one galvanic contact between the first electrically conductive antenna member (132) and the second electrically conductive antenna member (134).
