Description

The The invention relates to a steering column attachment device for a Motor vehicle according to the preamble of claim 1.

At a well-known, generic steering column attachment device for a motor vehicle is a steering column fixable. In addition, the steering column attachment device attachable to an end wall of the motor vehicle.

Concrete is this steering column attachment device one piece Made of a metal casting, giving a stable connection the steering column on the steering column attachment device possible is.

task The invention is a steering column attachment device for a Switching motor vehicle, on the one hand, a stable functionally reliable Connection to an end wall of the motor vehicle and on the other a stable and functionally reliable connection of a steering column is possible, and in the event of a collision of the motor vehicle, a transmission of intrusions from the front to the steering column is at least reduced.

These The object is achieved with the features of claim 1.

According to claim 1 is the steering column attachment device at least two parts of a steering column attachment part and a Built up end wall attachment part, so by means of at least one Sliding and connecting means are connected as they exceed a predetermined limit force relative to each other are displaced.

Advantageous in this steering column attachment device is that on the one hand on the steering column attachment part a functionally reliable attachment of a steering column is possible and on the other hand the A steering column attachment device with the end wall attachment part functionally reliable on an end wall of the motor vehicle can be attached. Through the connection by means of the at least one shifting and connecting means between the A steering column attachment part and the end wall attachment part is at a usual show the use of the steering system of the motor vehicle no relative displacement between the steering column attachment part and the front wall mounting part possible. The forces acting on it are smaller than the given limit force. At a limit force effect on the steering column mounting device, the bigger than is the limit force, is a corresponding relative shift between the Steering column mounting part and the end wall attachment part possible. Such a force is given for example in the event of a collision of the motor vehicle, in which the end wall is moved in the direction of the vehicle interior. This is due to the relative displacement between the steering column attachment part and the end wall attachment member a collision intrusion the front wall without a transmission of these intrusions on the steering column or on the steering wheel possible. Basically because of the possibility the relative displacement between the steering column attachment part and the End wall mounting part during assembly of the steering column mounting device on the end wall or during assembly of the steering column on the steering column mounting device a tolerance compensation possible. In addition, due to the shifting and connecting means used a high rigidity of the steering column connection possible.

In a further embodiment At least one holding means may be provided, with which the steering column attachment part and the end wall attachment part up to the limit force against each other durable are. When crossing the limit force can be the at least one holding means for a release the relative displacement between the steering column attachment part and end wall attachment part detachable and / or destructible be. The at least one holding means can by a clamping force be formed, which acts in the displacement and connection means. Basically, too be used a kind of shear pin, which exceeds the limit force is sheared off accordingly, so that a relative shift between the steering column attachment part and the end wall mounting part is functionally possible. in principle could the retaining means only after the installation of the steering column attachment device and a so associated tolerance compensation, by a relative displacement between the steering column attachment part and the end wall attachment part is possible on the steering column attachment part are arranged so that then a functionally safe use the steering system possible is. For example, in a collision of the motor vehicle exceeded the predetermined limit force, so the holding means is dissolved and / or destroyed in such a way that a relative shift is possible again.

According to a next embodiment, the at least one displacement and connection means may be disposed on the steering column attachment device such that the possible relative displacement between the steering column attachment part and the end wall attachment part approximately in the vehicle longitudinal direction. By such a relative displacement, the transmission of intrusions from the end wall to the steering column or to the steering wheel is largely excluded, especially in the case of collision of the motor vehicle, since the effective direction of the forces caused by the collision is approximately parallel with the possible relative displacement between the steering column mounting part and end wall mounting part, namely in the vehicle longitudinal direction.

In a further embodiment the at least one displacement and connection means can a fixable sliding connection may be formed. This is one simple and reliable design of the displacement and connection means proposed. Due to the fixability of the sliding connection is at a Force less than the predetermined limit force, the relative displacement between the steering column attachment part and end wall attachment part not possible.

In a preferred development, the sliding connection by a U-shaped in cross-section Rail part and an engaging rail in the rail part be formed. Preferably, the rail opposite part is designed so that the intervention in the rail part is performed undercut. In this case, the rail part on the steering column attachment part or on End wall mounting part and vice versa the Schienengegenteil be arranged on the end wall attachment part or on the steering column attachment part. In such an embodiment the sliding connection is a functionally reliable relative displacement at a force greater than the predetermined limit force is possible.

According to one next Design can the rail part and / or the Schienengegenteil integral to the steering column attachment part or be formed on the end wall mounting part. This can already in the manufacture of the steering column mounting part or the end wall fastening part, the rail part or the rail joint part be produced with integrated, so that further work steps, such as B. a mounting of the rail part on the steering column attachment part can advantageously be omitted. In addition, in the integral arrangement of the rail part and / or of the rail part on the steering column attachment part or at the end wall attachment part high strength between rail part or Schienengegenteil and steering column attachment part or end wall attachment part can be achieved, so that in total the steering column attachment device contributes to increasing the steering rigidity due to the high inherent rigidity.

According to one Continuing education can two parallel sliding joints on the steering column mounting device be arranged. This is the connection between the steering column attachment part and end wall attachment part advantageously increased, whereby also in a possible Relative displacement between the steering column attachment part and the End wall attachment part to be performed functionally reliable can.

Basically, too at least one support means be provided, with which the steering column attachment part in the Relative displacement between the steering column attachment part and the end wall attachment part in the original one Position supportable is. This ensures that, in particular in the case of a collision-related Displacement of the end wall and thus a displacement of the end wall attachment part in the direction of the vehicle interior, the steering column mounting part in about in its original Position remains, so that an undesirable displacement of the steering column attachment part and thus the steering wheel towards vehicle occupants largely is avoided.

Based a drawing is an embodiment closer to the invention explained.
