Abstract: An installation assembly for a loudspeaker, in particular in a vehicle door, contains a support element having a receiving opening for the loudspeaker, a loudspeaker basket having a flange, and a sealing element in the region of a mechanical abutment interface between the loudspeaker basket and the support element. During installation, the loudspeaker extends through the receiving opening on the support side, and the flange on the basket side abuts the support element with the interposition of the sealing element. The loudspeaker basket has a number of joining elements which correspond to joining contours of the support element to produce a bayonet coupling or a push-and-turn connection.

Abstract: A window lifter assembly is provided which comprises at least one carrier component and a guide rail fixed at the carrier component, which defines a path of adjustment for a window pane to be adjusted. At least three geometrically differently designed first, second and third fixing regions are provided at the guide rail, which in the properly connected state with a tab each engage into a cutout of an associated fixing region at the carrier component. Identically formed screws are used at the different first, second and third fixing points defined thereby, in order to fix the guide rail at the carrier component.
