Abstract
Fastening construction (1), in particular for an exterior vision unit of a motor vehicle, comprising a base part (3) which can be fixedly connected with a vehicle, and a rotation part (4) which is couplable with the base part (3) and which in coupled condition forms a central shaft (5) for pivotally bearing-mounting a housing of an exterior vision unit.
Claims21
A fastening construction comprising:
- a base part configured to be connected with a vehicle;
- and
- a rotation part, couplable with the base part and which in a coupled condition forms a central shaft, wherein
- the base part and the rotation part are provided with at least one cam and groove pair cooperating as a bayonet catch, such that in a first angular position of the rotation part with respect to the base part, the rotation part for the purpose of coupling can be displaced along a geometric axis to the base part to align the cam and groove pair for cooperation,
- the rotation part is pivotable about the geometric axis from the first angular position to a second angular position in which through cooperation of the cam and groove pair, the rotation part is locked with respect to the base part axially along the geometric axis, characterized in that the cam and groove pair is provided with surfaces cooperating under wedging action, and
- the rotation part further cooperates with a tightening part in a manner rotation-coupled via a breakable coupling, so that the tightening part, with the breakable coupling breaking, can rotate relative to the base part and a remaining portion of the rotation part from the second angular position about the geometric axis to a third angular position.

A method for fastening a fastening construction to a motor vehicle comprising:
- displacing a rotation part along a geometric axis to a base part to align at least one cam and groove pair of a bayonet catch for cooperation, and
- pivoting of the rotation part about the geometric axis from a first angular position to a second angular position through exertion of a tightening moment on an engaging part in which by a wedging action of the at least one cam and groove pair, the rotation part is locked with respect to the base part axially such that the rotation part relative to the base part is free from play along the geometric axis;
- and
- rotating of a tightening part from the second angular position relative to the base part and a remaining portion of the rotation part to a third angular position, as a result of the wedging action between the cam and groove pair, and breaking of a breakable coupling between the tightening part and the remaining portion of the rotating part, wherein
- the rotation part is connected to the base part via the bayonet catch, the base part being fastened to the motor vehicle.
