Abstract
A method for producing a covered steering wheel for a vehicle. A steering wheel skeleton is overmolded with a matrix material. A covering material is coated on its non-visible side with an activatable material. The coated covering material is applied to the overmolded steering wheel skeleton so that its non-visible side faces the overmolded steering wheel skeleton. Longitudinal edges of the covering material are joined together. The activatable material is activated with creation of an integral connection between the covering material and the matrix material.
Claims12
A method for producing a covered steering wheel for a vehicle, the method comprising:
- providing an overmolded steering wheel skeleton by overmolding a steering wheel skeleton with a matrix material;
- coating a covering material on a non-visible side with an activatable material to form a coated covering material;
- applying the coated covering material to the overmolded steering wheel skeleton so that the non-visible side faces the overmolded steering wheel skeleton;
- joining longitudinal edges of the coated covering material together;
- and
- activating the activatable material to form an integral connection between the covering material and the matrix material after the joining of the longitudinal edges of the coated covering material,
- wherein the activatable material is a foamable material that foams when activated.
