1. A method for producing a winding assembly for a protective device of a motor vehicle having a form-stable winding shaft and a flexible winding web held on the winding shaft such that the winding web can be wound up on the winding shaft and unwound from the winding shaft, the method comprising the following steps:
winding up a first portion of a flexible sheet-form material to form a plurality of winding layers;
carrying out form stabilization of the wound-up first portion to fix the winding layers to one another and maintain the winding layers in wound form, thereby forming the form-stable winding shaft with the form-stabilized wound-up first portion of the flexible sheet-form material; and
forming the flexible winding web with a second portion of the flexible sheet-form material adjoined to the first portion,
whereby the winding shaft and the flexible winding web are in a continuous one-piece form.
