Abstract
The invention relates to a tensioning device for a safety belt component, having a gas generator for generating a compressed gas, a piston which is driveable by the com-pressed gas, a traction cable which is attached to the piston and is connectable to a safety belt component to be set into a tensioning movement, a tensioner tube for receiving and gniding the piston, the tensioner tube having between the gas generator and the piston a cutout in its casing, and a cable guide which projects through the cutout into the tensioner tube and with which the traction cable is led out of the tensioner tube through the cutout, the cable guide consisting of at least two, preferably precisely two parts.

Tensioning device for a safety belt component, having
- a gas generator for generating a pressurized gas,
- a piston that can be driven by the pressurized gas,
- a traction cable which is connected to the piston and which can be connected to a safety belt component that is to be set into a tensioning movement,
- a tensioner tube for receiving and guiding the piston, wherein the tensioner tube has a cutout in its casing between the gas generator and the piston, and
- a cable guide which projects through the cutout into the tensioner tube and with which the traction cable is guided out of the tensioner tube through the cutout, wherein
- the cable guide consists of at least two, preferably exactly two, parts.
Method for producing a tensioning device, comprising the following steps in the specified order:
- a) providing an in particular rectilinear tensioner tube having a cutout in its casing,
- b) introducing a traction cable into the tensioner tube, wherein the traction cable is guided through the cutout,
- c) fastening a fastening means to the traction cable,
- d) attaching a multipart cable guide to the traction cable outside the tensioner tube on a portion, projecting beyond the cutout, of the traction cable, wherein the traction cable is surrounded in portions by the cable guide,
- e) inserting the cable guide into the cutout.
