The drive is located in a drive chamber which is formed by two plates, which extend parallel to one another and which are provided with a coating material, and which has a drive band of which at least one end is fastened to a drive shaft.

Drive unit for a safety belt tensioner

A drive for a belt tensioner for safety belts has a drive chamber formed between two plates. A drive band whose two ends are fastened to a drive shaft such that the drive band forms a loop which can be exposed to expanding gas discharged from a gas outlet such that the drive band winds off and drives the drive shaft. The drive band is fixed to the plates by a fixing apparatus at a position disposed between its ends.
