A seat (10) configured for detecting an occupancy state comprises an at least partially electrically conductive structural frame (14) comprising at least two fixation sites (22, 24) and an at least partially electrically conductive cushion-supporting spring (20) taut between the fixation sites. The cushion-supporting spring is electrically insulated from the structural frame. The seat comprises a cushion (16) supported by the cushion-supporting spring. The cushion-supporting spring and the structural frame are disposed in such a way that they are brought in electrical contact with each other when a force (34) is applied on the cushion that exceeds a predefined threshold force.

1. A seat configured for detecting an occupancy state, comprising: an at least partially electrically conductive structural seat frame comprising at least two fixation sites,a contact protrusion protruding from the seat frame and having an end, the contact protrusion comprising a first electrical contact area that extends off the end of the contact protrusion;one or more at least partially electrically conductive cushion-supporting springs taut between said fixation sites across said structural seat frame and electrically insulated from said structural seat frame, wherein the one or more cushion-supporting springs each comprises an opening formed in the electrical insulation, the opening exposing a conductive part of the respective cushion-supporting spring and forming a second electrical contact area on the respective cushion supporting spring; anda seat cushion supported by said one or more cushion-supporting springs, wherein the one or more cushion supporting springs are linked to the structural seat frame using electrically insulated coupling ends,wherein said one or more cushion-supporting springs and said structural seat frame are structured in such a way that the first electrical contact area and the second electrical contact area are brought into electrical contact with each other when an occupancy force applied on said cushion exceeds a predefined threshold force, wherein the electrical contact is detectable for detecting said occupancy state. 2. The seat as claimed in claim 1, wherein said cushion-supporting spring and said structural seat frame, are connected to a detection device configured for detecting said electrical contact between said first electrical contact area and said second electrical contact area. 3. The seat as claimed in claim 2, wherein said detection device is part of an information treatment device or configured for being connected with an information treatment device for transmitting information about said electrical contact to said information treatment device. 4. The seat as claimed in claim 2, wherein said detection device is electrically connected with said second electrical contact area. 5. The seat as claimed in claim 2, wherein said detection device is electrically connected with said first electrical contact area. 6. The seat as claimed in claim 3, wherein said detection device comprises or is configured to operate as at least one of an ohmmeter, a voltmeter and an ammeter. 7. The seat according to claim 3, wherein the information treatment device comprises an onboard computer or a safety bag inflating apparatus. 8. The seat as claimed in claim 1, wherein said contact protrusion is mechanically adjustable in accordance with a desired threshold force. 9. The seat as claimed in claim 1, wherein said contact protrusion is resilient. 10. The seat as claimed in claim 1, wherein said one or more cushion-supporting springs are electrically insulated from said structural frame by a plastic material. 11. A vehicle comprising a seat configured for detecting an occupancy state, comprising: an at least partially electrically conductive structural seat frame comprising at least two fixation sites,a contact protrusion protruding from the seat frame and having an end, the contact protrusion comprising a first electrical contact area that extends off the end of the contact protrusion;one or more at least partially electrically conductive cushion-supporting springs taut between said fixation sites across said structural seat frame and electrically insulated from said structural seat frame, wherein the one or more cushion-supporting springs each comprises an opening formed in the electrical insulation, the opening exposing a conductive part of the respective cushion-supporting spring and forming a second electrical contact area on the respective cushion supporting spring; anda seat cushion supported by said one or more cushion-supporting springs, wherein the one or more cushion supporting springs are linked to the structural seat frame using electrically insulated coupling ends,wherein said one or more cushion-supporting springs and said structural seat frame are structured in such a way that the first electrical contact area and the second electrical contact area are brought into electrical contact with each other when an occupancy force applied on said cushion exceeds a predefined threshold force, wherein the electrical contact is detectable for detecting said occupancy state. 12. A vehicle comprising a seat, as claimed in claim 2, a vehicle body at an electrical. reference potential, and wherein said detection device is configured for detecting said electrical contact by comparing an electrical potential of said one or more cushion-supporting springs with said electrical reference potential of said vehicle body. 13. The vehicle as claimed in claim 12, wherein said detection device and said structural seat frame are electrically connected with said vehicle body.
