ABSTRACT:
An inflatable air-bag is disclosed which is provided with a controllable vent formed in the fabric of the air-bag. The vent comprises a hole formed in the fabric of the air-bag and a flexible vent tube which extends inwardly of the air-bag from the hole so as to terminate in an open free-end located within the air-bag. The free end of the vent tube is normally tethered within the air-bag so as to maintain the vent in a closed condition but is releasable in response to a signal so as to open the vent. In one arrangement the vent tube is fixed to the inner surface of the air-bag around the hole and is configured so as to have a tapering cross-section which is smaller at the free-end of the tube then at the fixed end of the tube. In another arrangement the vent tube is fixed to the inner surface of the air-bag fabric around the vent hole by stitching which runs around the periphery of the hole and which is located within the vent tube.
