Abstract
Abstract A head-protecting curtain in a motor vehicle is stored folded at the roof rail. In the event of a collision, the curtain is moved in the interior into a protecting position in front of a vehicle door, whereupon it then covers at least an upper area of the door opening and is stretched horizontally. The head-protecting curtain has at least two curtain sections that remain connected during the impact, said sections being separable from one another after the impact, starting at the bottom edge of the head-protecting curtain, along a parting line for at least part of the height.
