Abstract

A safety arrangement for a motor vehicle is disclosed which comprises an air-bag module (1) having an inflatable air-bag (5) in fluid communication with an inflator (4). An internal tether (14) is provided having a first end (15) and a second end (16). The first end (15) of the tether is connected to a restrainable part (13) of the air-bag, whilst the second end (16) of the tether is free from connection with the air-bag but is initially trapped between the folds or rolls of an initially folded or rolled part of the air-bag. The arrangement is such that, upon inflation of the air-bag, the tether serves to restrain the restrainable part (13) of the air-bag until such time as the folded or rolled part of the air-bag (9) becomes sufficiently unfolded or unrolled to release the second end (16) of the tether (14).
