Abstract: An energy absorber for use as impact protection in a motor vehicle, in particular in the region of the doors, is provided. The energy absorber can be formed as a plastics material component and comprises a plurality of ribs which together form polygonal hollow chambers. In manufacturing the energy absorber, a tool parting line of the manufacturing tool is defined such that the parting line defines at least two regions of the energy absorber displaying differing energy absorption characteristics. Upon impact, the energy absorber follows a force/distance curve which first rises linearly and then continues constantly.

Abstract: A pre-assembly unit for a motor vehicle and for connection of such with a door frame of the motor vehicle, comprising a window frame, a side window guided at least within the window frame, a window lifting mechanism, which is joined to the side window in order to raise or lower it, and an equipment carrier connected to but disconnectable from the window frame with a wet side (N) and a dry side (T) for dividing the door frame into a wet and a dry area is provided. At least one fixing means, which joins the window lifting mechanism to the equipment carrier and can be undone from the dry side of the equipment carrier is also provided. At least one assembly preparation is provided on or in the window lifting mechanism, and is accessible from the dry side of the equipment carrier for connecting the window lifting mechanism to the door frame. A corresponding motor vehicle door as well as an assembly and disassembly method is also provided.

Abstract: The present invention concerns a modular holder system (1), in particular for use in motor vehicles, with a carrier unit (3) and a number of holder modules (2) for objects. The holder modules (2) are each attached to the carrier unit (3) detachably via a coupling device (5, 6) which has at least one form-fit (6) and one force-fit (5) locking part.
