SEAT CONFIGURED FOR OCCUPANCY STATE DETECTION
First Claim
1. A seat, e.g. a vehicle seat, configured for detecting an occupancy state, comprising:
- an at least partially electrically conductive structural frame comprising at least two fixation sites,an at least partially electrically conductive cushion-supporting spring taut between said fixation sites and electrically insulated from said structural frame, anda cushion supported by said cushion-supporting spring,wherein said cushion-supporting spring and said structural frame are disposed in such a way that they are brought in electrical contact with each other in response to a force applied on said cushion that exceeds a predefined threshold force.

Abstract
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.
