Abstract

Improvements introduced in the manufacture of steering wheels for automobiles. In a manufacturing process for automotive leaflets, at least two thermoplastic materials capable of being molded by multiple injection techniques are used to obtain injected areas that enclose the rings and metal arms of the leaflets and other coverings, said thermoplastic materials being different characteristics to provide injected areas with different degrees of rigidity and with the finish to the touch and appearance that is desired. The external finishing part itself of the central area of the steering wheel will be able to form the housing intended to contain the components of the airbag module or other functions. **figure** (Machine-translation by Google Translate, not legally binding)
