Abstract
A winding assembly for a protective device of a motor vehicle, and a method for producing such a winding assembly. Such a winding assembly includes a form-stable winding shaft and a flexible winding web held on the winding shaft such that it can be wound up and unwound. The winding shaft is formed by a form-stabilized wound-up first portion of a flexible sheet-form material and the flexible winding web is formed by a second portion of the flexible sheet-form material adjoining the first portion, whereby the winding shaft and the winding web are in continuous one-piece form.

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.
A method for producing a winding assembly for a protective device for use in a motor vehicle, the method comprising:
- providing a sheet of continuous flexible material having first and second portions;
- winding up the first portion of the continuous flexible material to form a wound-up first portion including a plurality of winding layers;
- stabilizing the plurality of winding layers of the wound-up first portion to fix the winding layers to one another and form a form-stable winding shaft;
- and
- forming a flexible winding web from the second portion of the continuous flexible material which remains after the step of winding up the first portion and producing a winding assembly having the form-stable winding shaft and the flexible winding web in a continuous one-piece form.
