Steering wheel for a motor vehicle
View Patent ↗A steering wheel for a motor vehicle includes a skeleton ( 10 ) and a rear-side covering part. The skeleton forms a hub ( 12 ), at least one spoke ( 14 ) and an upper part ( 16 ) of a steering wheel rim. The steering wheel also includes a rear-side covering part ( 18 ) made of plastic, which at least partially covers a lower area of the central part of the steering wheel and also constitutes a lower part of the steering wheel rim.
1. A steering wheel for a motor vehicle, the steering wheel comprising a skeleton and a rear-side covering part,
the skeleton forming a hub, at least one spoke and only an upper part of a steering wheel rim,
the rear-side covering part being made of plastic and at least partially covering a lower area of a central part of the steering wheel, at least one rib being formed in the rear-side covering part,
the rear-side covering part also constituting only a lower part of the steering wheel rim which complements the upper part of the steering wheel rim formed by the skeleton.
2. The steering wheel as recited in claim 1 , wherein an intermediate layer of soft foam is attached directly to the steering wheel rim and the rear-side covering part and completely surrounds both the steering wheel rim and the rear-side covering part, a leather covering being attached directly to the intermediate layer and being the outermost layer of the steering wheel rim.
3. The steering wheel as recited in claim 2 , wherein the steering wheel rim, which is formed by the skeleton and the covering part, defines the exterior geometry of the steering wheel rim provided with the intermediate layer and the leather covering.
4. The steering wheel as recited in claim 2 , wherein the total thickness of the intermediate layer and the leather covering does not substantially exceed 3 mm.
5. The steering wheel as recited in claim 1 , wherein the covering part defines the exterior geometry of the lower area of the central part of the steering wheel.
6. The steering wheel as recited in claim 1 , wherein at least one of the ribs is attached to the skeleton by one of an ultrasonic welding, heat caulking, screw, glue, and snap-action hook connection.
7. The steering wheel as recited in claim 1 , wherein at least one insert is provided in the steering wheel rim as formed by the skeleton and the covering part and is attached to the covering part.
8. The steering wheel as recited in claim 7 , wherein the insert is integrated in the covering part.
9. The steering wheel as recited in claim 1 , wherein the upper and lower parts of the steering wheel rim formed by the skeleton and by the rear-side covering part form a steering wheel rim having a relatively round outer surface.
