Abstract
The invention relates to a belt tensioning drive which has an electric motor, a gear shaft and an output wheel. The electric motor drives the gear shaft via a first gear which is a worm gear. The gear shaft, for its part, uses a second gear to drive the output wheel which is connected in a rotationally fixed manner to the winding shaft of the seatbelt. This second gear is also a worm gear.

1-5. (canceled)
A belt-tensioning drive comprising:
- an electric motor (2),
- a gear mechanism shaft (3)
- an output element (4),
- the electric motor (2) driving the gear mechanism shaft (3) via a first gear mechanism (2d, 3b),
- the gear mechanism shaft (3), for its part, driving the output element (4) via a second gear mechanism (3d, 4a),
- the second gear mechanism (3d, 4a) being a worm gear mechanism or a spur gear mechanism,
- the first and the second gear mechanism being in the form of a 90° deflection gear mechanism, and
- the output element (4) being an output gear whose axial direction runs parallel to the shaft (2c) of the electric motor (2).
