Steering wheel and a method for manufacturing a steering wheel
Abstract:
A steering wheel (1) has spokes (5) extending outwardly from a boss (3) to a rim (6). The rim has an inner frame (6) with an integrally moulded plastics coating (9) which has an internal cavity (11). The presence of the cavity minimises the overall weight of the steering wheel. The cavity is formed by initially injecting hot plastics material into a substantially vertical mould and subsequently blowing air into the lower part of the mould after some of the plastic adjacent the mould of walls has cooled.
