Airbag arrangement
First Claim
1. A fabric air-bag, the air-bag being provided with a controllable vent formed in the fabric of the air-bag, the vent normally being maintained in a closed condition by a fabric element which is retained by a clamp, the clamp being capable of releasing the fabric element in response to a signal from a sensor, wherein the fabric element is in the form of a re-entrant tube extending into the interior of the air-bag, the free end of the tube defining the controllable vent and the re-entrant tube being held closed by the clamp prior to deployment of the air-bag so that gas cannot flow through the tube.

Abstract
An air-bag is provided with a controllable vent, for example a tube, which is normally maintained in a closed condition by being retained by a clamp. The clamp is opened in response to a signal from a sensor. The clamp may be opened when it is desired for the air-bag to have a “soft” inflation, thus permitting a relatively high rate of flow of gas exiting from the air-bag.
