Abstract
Abstract A vehicle includes a seat for supporting an operator in seated position, a steering column supporting a steering wheel for steering the vehicle, and a source of pressure fluid releasable in response to the vehicle receiving an acceleration pulse of predetermined amplitude and time. An occupant restraint for the operator includes an inflatable cushion of generally frustoconical shape surrounding the column and wheel and having its apical end mounted on the column adjacent the instrument panel of the vehicle. When the cushion is inflated, the basal end thereof is located in a position for impact by the operator.
