1. A method for a seat belt system (10) in a vehicle (14), the seat belt system (10) comprising a control unit (36) and at least one seat belt (18) having an extendable webbing (20) and a webbing extension measuring device (30), comprising the steps of:
a) determining whether a vehicle seat (16) is occupied,
b) determining whether the webbing (20) is in a storage position, if the vehicle seat (16) is not occupied, and
c) outputting a warning signal, in particular via an output device (34), if the webbing (20) is not in the storage position and the vehicle seat is not occupied.
 
10. A method for a seat belt system (10) in a vehicle (14), wherein the seat belt system (10) comprises a control unit (36) and at least one seat belt (17) having a belt retractor (27) integrated in the vehicle roof, an extendable webbing (20) with a fastener (21) and an end fitting fastener (56) and a webbing extension measuring device (30), including the steps of:
a) determining whether the end fitting fastener (56) and the fastener (21) are locked,
b) determining whether the webbing (20) is in a first storage position if the end fitting fastener (56) and the fastener (21) are both not locked,
c) outputting a warning signal via an output device (34) if the webbing (20) is not in the first storage position when the end fitting fastener (56) and the fastener (21) are both not locked, and
d) determining whether the webbing (20) is in a second storage position if the end fitting fastener (56) is locked and the fastener (21) is not locked,
the warning signal being output via the output device (34) when the webbing (20) is not in the second storage position while the end fitting fastener (56) is locked and the fastener (21) is not locked, and when the webbing (20) is not in the first storage position while the end fitting fastener (56) and the fastener (21) are both locked, the webbing (20) in the first storage position being completely wound onto the belt retractor (27) and the webbing (20) in the second storage position being only partially wound onto the belt retractor (27).
