Inflation device for vehicle airbag

摘要

The vehicle airbag inflation device (10) incorporates a storage chamber (18). This has an axis with first and second opposite ends which are spaced apart from each other at a distance along the axis. The chamber has a circular cross-sectional shape at all points along the axis whereby the ratio of the distance to the greatest cross-sectional dia. of the storage chamber lies within the region 0.75 to 1.25. The storage chamber has an essentially cylindrical shape with a length between the opposite ends and an essentially constant dia. along the length. The length is equal to the dia.
