Abstract
An inflatable airbag for an airbag unit with at least one tensioning cord which can be fixed to the vehicle body. The cord can be tensioned when the airbag is inflated and limits the spreading of the airbag during inflation. The tensioning cord engages with the airbag in at least one area over at least one pair of adhesive surfaces comprising two surface elements in the form of a hook surface and a counter surface. One of the surfaces is allocated to the airbag and the other surface is allocated to the tensioning cord. The surfaces glide past each other during a relative movement along a first direction when the airbag is inflated. The surfaces engage with each other when relative movement along a second direction which is substantially opposite to the first direction occurs after inflation.
