Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
Method for manufacturing a steering wheel, particularly for a motor vehicle, of the type including a steering wheel skeleton (1) provided with an open dish (2) for receiving at least one inflatable bag (3) in a folded state, and with a soft covering (5) made of plastic, comprising the steps of: a) forming a steering wheel skeleton integrally and in one piece with a reception dish; b) disposing a folded, inflatable bag in the dish; c) closing off an opening of the dish with a sealing material (4) which can tear when the bag inflates; d) disposing the steering wheel skeleton together with the integral reception dish provided with the inflatable bag and closed with the sealing material in a mould; and e) injecting a plastic material into the mould to form a soft covering around the skeleton, the dish, and the sealing material.
Claim 2
Dependent Claim
