Abstract:
A guide rail assembly for motor vehicle window lifters and a method for the production thereof. Two guide webs having protrusions formed thereon form a guide rail on a carrier plate made from a plastic material. The guide webs may be bent elastically inwards or outwards, enabling the driving element to be clipped on by pushing it on in the vehicle's transverse direction y and considerably simplifies production in an injection moulding process because the guide rail may be removed by elastically bending the guide rails such that a smaller number of sliders is required in the moulding tool. In one embodiment, there is also provided a driving element comprising a body of a first material and, securely held therein, sliding inserts comprised of a second material which material ensures a particularly good tribological pairing with the material of the associated guide web.
Abstract:
An assembly carrier for installation into a motor vehicle is provided. The assembly carrier comprising a large-area carrier body which is molded at least partially from fiber-reinforced plastic, fastening points, which are provided on the carrier body, for fastening functional components of a motor vehicle to the carrier body, and a gate mark which projects from the carrier body and which represents a section of the path along which the molding compound for molding the assembly carrier was conducted into a cavity, which forms the carrier body, of a molding die. The gate mark has at least one longitudinally extended gate section which is curved—in cross section through the carrier body and the gate mark—and whose longitudinal sides which are situated opposite, and which face away from, one another run in each case along a curved path and merge in each case along the respective path into the carrier body.

Abstract:
The invention relates to a use of a composition containing a partly crystalline, partly aromatic polyamide for producing at least a part of an adjusting device of a motor vehicle. The composition is impact-modified by addition of at least one elastomer with a proportion of 1% to 10% in the composition.
