First Claim
1. An air bag unit comprising:
- an inflatable airbag;
a cord operatively connected to the airbag, wherein the cord is arranged to be tautened during inflation of the airbag to thereby limit the spread of the airbag;
a first adhesive face connected to the cord;
a second adhesive face connected to the airbag;
wherein the adhesive faces are configured to allow relative movement between the airbag and the cord in a first direction during inflation of the airbag; and
wherein the first adhesive face is configured to engage the second adhesive face to prevent relative movement between the airbag and the cord in a second direction generally opposite to the first direction after inflation of the airbag.

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.
