BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a steering wheel rod support for vehicles, which support is designed partly to be displaced a distance in the axial direction of the steering wheel rod and partly to be tilted about a transverse spindle (axis).
Such steering wheel rod supports have to meet many different requirements, which individually can be solved in different ways, but these solutions can be difficult to combine in the same steering wheel rod support. Besides the general requirement that a device of this type has to be simple and inexpensive to manufacture and mount in vehicles, the following illustrative requirements can be mentioned: stresses, which may materialize, without being damaged; movements than the required movements must be possible; be placed in such a way, that they do not obstruct or interrupt other functions in the vehicle; efficient in order not to allow any unintentional readjustments; accessible and easy to actuate; and close to the steering wheel in order to give the steering wheel a pronounced angular change when a tilting takes place, etc. Many different constructions of slideable and tiltable steering wheel rod supports are known, all of which are burdened with deficiences or inconveniences in some respects.
DESCRIPTION OF THE PRIOR ART
French patent publication number 2.360. 454 (Chrysler France) relates to a slidable and tiltable steering wheel rod support, in which the tilting spindle is located at a comparatively large distance from the steering wheel, which results in that the steering wheel, when a tilting is done, assumes a very small angular change, depending on the long pivoting radius between the steering wheel and the tilting spindle. Also, the lock plates, which necessarily are somewhat resilient in order to obstruct the sliding the tilting movement, form mounting and suspension means for the entire steering wheel rod support in the car, which means that the support will be resilient and somewhat instable and can be experienced as unstable and resilient. Also, it may be difficult to carefully steer the sliding and tilting movements, and it is difficult and heavy to actuate the lock devices of the slidable and tiltable steering wheel rod support and the required stable locking action is normally not obtained, and the steering wheel rod support jointly with the steering wheel might unintentionally readjust while driving.
German document 17 80 061, laid open to public inspection (Daimler Benz), relates to a steering wheel rod support, which mainly has the same inconveniences as the known construction discussed above.
SUMMARY OF THE INVENTION
The purpose of the present invention is to solve the problem of producing a steering wheel rod support, which is not burdened with the deficiences of the already known constructions and which fulfills the considerable requirements stated above for a steering wheel rod support having a sliding and tilting function.
In accordance with the present invention the steering wheel rod support comprises a fastening means, such as a stationary, stable box, by means of which the entire steering wheel rod support can be mounted in the vehicle a bearing housing for the steering wheel rod, lock plates fastened to the bearing housing, a lock device which cooperates with the lock plates and is designed to lock the steering wheel rod support in an adjusted position, as well as an actuation device for the lock device.
The bearing housing, jointly with the steering wheel rod, is, by means of sliding grooves or the like in the fastening means and in the lock plates, mounted in such a way, in the fastening device, that partly it can be displaced in a longitudinal direction and partly be tilted into any adjusted longitudinal position whatsoever about a tilting link, which is located comparatively close to the steering wheel.
Through this constructive design the following advantages are obtained: housing to the fastening means or the box via the tilting link, consequently only insignificantly via the lock plates. In this w
