Patent ID: 7111396

Claim:
A process for the production of a steering wheel for motor vehicles, comprising the steps of: providing a substantially circular-shaped metal core ( 11 ); burying said metal core ( 11 ) inside a synthetic resin ( 12 ), thereby forming a steering wheel body; preparing a pair of outer covering shells ( 13 a , 13 b ) by means of hot forming of composite elements with a laminated structure, said shells ( 13 a , 13 b ) having a complementary shape and being suitable to be placed over said steering wheel body and joined together along their edges; preparing a system ( 14 ) for connecting and fastening to each other said shells ( 13 a , 13 b ), said system being constituted by a thin element ( 14 ) that is fixed to the inner side of one ( 13 a ) of said shells in such a way that both edges of said thin element ( 14 ) protrude over the edges of said shell ( 13 a ), whereby the surface of said thin element ( 14 ) protruding over the edges of said shell ( 13 a ) forms an area for fastening said thin element ( 14 ) to the inner side of the other shell ( 13 b ); and joining said two shells ( 13 a , 13 b ) together along their edges, thereby fixing said other shell ( 13 b ) to the said protruding surface of said thin element ( 14 ); and joining said two shells ( 13 a , 13 b ) together along their edges, thereby fixing each respective shell ( 13 a , 13 b ) to the said protruding surface of said thin elements ( 14 a , 14 b ).
