Abstract
A safety apparatus for road and other vehicles, of belt form. The belt is essentially tubular but is normally in a collapsed condition, and is provided with resilient means which on operation of the belt cause the belt to expand in volume and to be filled with air through a one-way valve. The belt can be held in the collapsed condition by vacuum.
