Abstract:
1. A plastic slip clutch for adjustable drives in automobiles, with two clutch elements that engage with each other and have a linear design, where at least one of these clutch elements exhibits a profile with n plastic elements which engage in form-fitting and force-fitting fashion with an opposing profile with m opposing elements belonging to the other clutch element in order to transmit linear drive forces, and where one of the profiles exhibits the n plastic elements for the transmission of force, such that the n plastic elements become elastically deformed under the effect of a force that exceeds a specific threshold force, wherein each of the n plastic elements has a bridge, which extends in axially parallel fashion on its outer surface facing the opposing profile, the bridge having a ridge and only a single hole defined by the bridge and the clutch element to which the bridge belongs, wherein the n plastic elements engage with the m opposing elements for the transmission of force, wherein the elastic deformation of the n plastic elements allows the corresponding profile to be deformed and the opposing profile to slip through, and wherein n is the number of the plastic elements and m is the number of the opposing elements, with m being greater than n.
