DURCH FELDEFFEKT STEUERBARE VERRIEGELUNGSÜBERWACHUNGSVORRICTUNG UND VERWENDUNGSVERFAHREN

摘要

A seat belt buckle (12) includes a latch mechanism (20) and a field effect device (26). The latch mechanism (20) includes a latch (42) which is movable into and out of a locking position in which it engages a seat belt tongue (16) to interlock the tongue (16) with the latch mechanism (20). The field effect device (26) provides a first output if the seat belt tongue (16) is not interlocked with the latch mechanism (20) and provides a second, different output if the seat belt tongue (16) is interlocked with the latch mechanism (20).
