<p>A airbag for protecting the driver of a vehicle in the event of a frontal collision is designed for early coupling with the driver whilst initially allowing the driver's head to move forwardly sufficiently to minimize the risk of neck injury. The airbag is made by first providing a flat fabric construction (10) in which first and second superimposed fabric layers are secured together along seams (30, 32, 34, 36) to provide an elongated single bag which is then folded about a fold line (26) intermediate its ends to provide first (20) and second (22) cells, which are connected by triangular gussets (27, 29) on either side. One of the cells (20) is connected with an inflator in the steering wheel hub to be inflated directly from the inflator whilst the other cell (22), nearer the driver, is inflated from the first cell (20) via the restriction afforded by the fold (22), and additionally by seams (35) extending partially along the fold, so that the other cell (22) inflates more slowly and provides an initially softer cushion for engagement with the head and thorax of the driver.</p> |
