| Zusammenfassung: | The device has a lock detection mechanism (7) for detecting closing condition of a seat belt lock (6) of a seat belt (1). A belt excerpt sensor (8) detects expansion length of belt straps (2, 2', 2'') of the seat belt. A belted condition of a passenger (9) is indicated as belt status when a lock detection unit detects the closing condition of the seat belt lock, and the belt excerpt sensor detects the expansion length. A warning signal is produced during insertion and locking of a belt tongue (5) into the seat belt lock when the belt runs behind the passenger. |
