Abstract
A method of folding an air-bag is disclosed. The air-bag is initially located in a substantially flat condition. Two side portions of the air-bag are rolled inwardly towards the gas generator and are then folded back (9, 10) towards the centre of the air-bag, thus releasing tension in the upper layer of fabric between the two rolls. The rolled regions are then themselves rolled inwards form the opposed ends thereof and are again finally turned back, again to release any tension in the central region of the fabric. Consequently, the central region of the fabric, which is located opposite the gas generator, is slack, enabling that part of the fabric to move away from the gas generator relatively easily when the gas generator is activated.
