Patent ID: 6892602

Claim:
A device for fastening a casing tube switch module to a casing tube of a steering wheel shaft when a steering wheel is mounted on the steering wheel shaft, the device comprising: a clamping element arranged coaxially between the casing tube and the casing tube switch module, the clamping element operable for exerting a clamping force in a direction extending radially out from the steering wheel shaft when tensioned; and a bearing operable for rotationally decoupling the steering wheel from the casing tube switch module, the bearing having a stator side operable for transferring an axial motion of the steering wheel as the steering wheel is mounted on the steering wheel shaft to the casing tube switch module such that the casing tube switch module moves axially with respect to the casing tube and the clamping element and tensions the clamping element to apply the clamping force in a direction extending radially out from the casing tube and radially toward the casing tube switch module in order to fasten the casing tube switch module to the casing tube.
