System for detecting presence of person in vehicle seat, comprises insulated conductor networks under seat and back which are connected to electronic control unit and detect person by electric field

摘要

The vehicle seat (1) has lower seat (3) and back (4) which are covered by a flexible mattress and leather type skin. Insulated networks (8,15) supported by springs (17) from adjacent parts (9,16) of the seat frame are connected to an electronic control unit (19) within the seat. The electronic control unit applies an electric field to the insulated networks which allows the presence and posture of an occupant to be detected
