Abstract

The invention relates to a belt tightening drive (1) for tightening a seat belt (2) that can be wound about a winding shaft (4), comprising a spindle shaft(l3) driven by a drive unit (3) and a worm drive (10) with a worm supported in a torque-proof fashion on the spindle shaft(l3) and a driven wheel (1 l), engaged therewith and supported in a torque-proof fashion on the winding shaft (4). According to the invention it is provided that the worm (12) comprises a first toothed section (a) with a first toothed geometry (14), with in the first position (I) of the worm (12) the first toothed section (a) engages the driven wheel (1 l),the worm (12) comprises at least a first toothed section (a) and following a second toothed section (b) with a second toothed geometry (l5), with the first and second toothed geometries(l4, 10) being embodied differently, and depending on an axial application of force upon the worm (12) an axial displacement of the worm (12) is caused between a first position (I), in which the worm (12) engages the driven wheel (1 1) via the first toothed section (a), and a second position in which it engages the driven wheel (1 1) via its second toothed section (b),
