The connection of the two longitudinal edges is located on the underside of the steering wheel at a distance from the inner circumference of the steering wheel rim.
The cover is made of a single-piece material blank whose two longitudinal edges are connected to each other along the steering wheel rim. The connection of the two longitudinal edges is located on the underside of the steering wheel at a distance from the inner circumference of the steering wheel rim.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a steering wheel with a steering wheel rim which is covered by a cover or casing of leather or a leather-like material. The cover or casing is made of a single-piece material blank whose two longitudinal edges are connected to each other along the steering wheel rim.
1. Field of the Invention The present invention relates to a steering wheel with a steering wheel rim which is covered by a cover or casing of leather or a leather-like material. The cover or casing is made of a single-piece material blank whose two longitudinal edges are connected to each other along the steering wheel rim.
2. DescriPtion of the Related Art Steering wheels whose rims are provided with a cover of leather or a leather-like material are manufactured by initially manufacturing the steering wheel proper and subsequently surrounding the steering wheel rim with the cover, wherein the cover is made of a single-piece blank which is placed around the steering wheel rim and is fastened to the steering wheel rim by connecting the two longitudinal edges of the blank.
In conventional steering wheels, the two longitudinal edges of the blank forming the cover are connected to each other along the inner circumference of the steering wheel rim by sewing or another similar type of connection, so that the connection is not located in the area of the gripping surfaces of the steering wheel. However, independent of the selected type of connection of the two~longitudinal edges of the blank forming the cover, there is the difficulty that the location of the connection at the inner circumference of the steering wheel rim is not easily accessible, so that the manufacture of the connection is difficult and the costs of the steering wheel become higher.
It is, therefore, the primary object of the present invention to improve a steering wheel whose rim is provided with a cover of leather or a leather-like material, so that the manufacture of the steering wheel is significantly simplified, while the advantages of the known steering wheels are still present.
SUMMARY OF THE INVENTION
In accordance with the present invention, the connection of the two longitudinal edges of the blank forming the cover is located on the underside of the steering wheel at a distance from the inner circumference of the steering wheel rim.
In accordance with an advantageous feature of the invention, the distance at which the connection between the two longitudinal edges of the blank forming the cover is moved downwardly from the inner circumference of the steering 2ol7288 wheel rim is approximately one-fourth to one-fifth of the cross-section of the steering wheel rim~. Accordingly, the connection of the two longitudinal edges is still outside of the gripping surface. However, the connection is now at a location which is more accessible and the manufacture of the steering wheel is made simpler.
The steering wheel according to the invention makes it possible to provide a connection of the two ends of the blank from the steering cover which is continuous and is located outside of the connection points of the steering wheel spokes with the steering wheel rim. In addition, the invention provides the possibility of using various different types of connections of the longitudinal edges of the blank forming the cover.
In accordance with a preferred embodiment of the invention, the connection of the two longitudinal edges of the blank forming the cover is a seam, preferably cross-stitch seam.
In accordance with another useful embodiment of the invention, the connection of the two longitudinal edges of the blank forming the cover located at a distance downwardly from the inner circumference of the steering wheel rim is obtained by a butt-jointed adhesive connection and an ornamental seam is provided at the connection for improving the optical appearance.
In accordance with another advantageous embodiment of the invention, the connection of the two longitudinal edges of the blank forming the cover located at a distance downwardly from the inner circumference of the steering wheel rim is obtained by gluing together overlapping, beveled longitudinal edges of the blank and by providing an ornamental seam at the connection for improving the optical appearance.
In accordance with another special feature of the invention, the two longitudinal edges of the blank forming the cover may have flanges which are glued together and are inserted in a circumferential recess in the steering wheel arrangement located at a distance downwardly from the inner circumference of the steering wheel rim.
In accordance with a further special embodiment of the invention, the connection of the longitudinal edges of the blank forming the cover located at the distance downwardly from the inner circumference of the steering wheel rim is obtained by clamping the longitudinal edges together, wherein the longitudinal edges of the cover are inserted in a circumferential groove in the steering wheel rim and are clamped relative to each other by means of an insert and, if necessary, are directly or indirectly glued together.
While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
