Abstract
A procedure for the manufacture of a steering wheel for motor vehicles consisting of an outer covering in composite material, comprising the preparation of the covering by means of composite elements with a laminar structure, the hot forming of these elements in order to obtain a pair of complementary shells (13a, 13b), the assembly of the shells on the opposite sides of the steering wheel, in which the body of the steering wheel consists of a metal core (11) buried inside synthetic resin, and in that at least one of the shells forming the opposite sides of the covering is equipped with a support element (14a, 14b) which allows it to be coupled to the other shell complementary to it.
Claims2
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 (13a, 13b) by means of hot forming of composite elements with a laminated structure, said shells (13a, 13b) 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 (13a, 13b), said system being constituted by a thin element (14) that is fixed to the inner side of one (13a) of said shells in such a way that both edges of said thin element (14) protrude over the edges of said shell (13a), whereby the surface of said thin element (14) protruding over the edges of said shell (13a) forms an area for fastening said thin element (14) to the inner side of the other shell (13b);
- and joining said two shells (13a, 13b) together along their edges, thereby fixing said other shell (13b) to the said protruding surface of said thin element (14);
- and joining said two shells (13a, 13b) together along their edges, thereby fixing each respective shell (13a, 13b) to the said protruding surface of said thin elements (14a, 14b).
