Abstract
A method for manufacturing a steering wheel involves moulding a steering wheel skeleton 1 and an air bag reception dish 2 integral therewith, placing a folded inflatable bag 3 in the dish, and closing the dish opening with a sealing material 4 which can tear when the bag inflates. The steering wheel skeleton together with its dish 2 filled with the bag 3 and covered with the sealing material 4 is then placed in a mould, and plastic is injected into the mould to form a soft outer covering 5 around the skeleton.
