1. A seat belt retractor includes

-a belt reel (2), and

-a drive means for driving the drive means,

it is characterized in that the preparation method is characterized in that,

the belt reel (2) and the drive are each configured as a belt reel module (1) and a drive module (20) in modular fashion as a module, and

-the web spool module (1) and the drive module (20) can be connected to each other in different orientations via a structural interface.

2. The seatbelt retractor according to claim 1, wherein the assembly of the seatbelt retractor module (1) comprises

-the belt reel (2) and/or

-a locking device (7) which, when activated, locks the belt reel (2) in the pull-out direction, and/or

-a drive spring (5) tensioning the belt reel (2) in a winding direction, and/or

-simple or adaptive force limiting means (6), and/or

-one or more sensor devices (8).

3. The seatbelt retractor according to claim 1 or 2, wherein the assembly of the drive means module (20) comprises

-an electric motor (24) and/or

-a pyrotechnic drive unit (25) and/or

-a transmission coupled with the electric motor (24) and/or the pyrotechnic drive unit (25), and/or

-a control unit to operate the electric motor (24) and/or the pyrotechnic drive unit (25).

4. The seatbelt retractor according to one of the preceding claims, characterized in that-the seatbelt retractor module (1) and the drive device module (20) each have a housing (3, 21).

5. The seatbelt retractor according to claim 4,

the structural interface is formed by an adapter part (14) which connects the housing (3) of the seatbelt reel module (1) to the housing (21) of the drive module (20), said adapter part defining the orientation of the seatbelt reel module (1) relative to the drive module (20) by means of its shaping.

6. The seatbelt retractor according to claim 4 or 5,

-the belt reel module (1) and/or the drive module (20) has a carrier plate (4, 22) supported on the housing (3, 21) on the side facing the structural interface, on which carrier plate the belt reel (2) and/or the drive is supported.

7. The seatbelt retractor according to any one of claims 4 to 6,

the housings (3, 21) of the web spool module (1) and the drive module (20) are tubular.

8. The seatbelt retractor according to any one of claims 4 to 7,

-the housings (3, 21) of the web spool module (1) and the drive means module (20) have the same cross-sectional shape.

9. The seatbelt retractor according to any one of claims 4 to 8,

-the adapter part (14) and at least one of the housings (3, 21) of the web spool module (1) and/or the drive module (20) have the same cross-sectional geometry at least in the region of the connection.

10. The seatbelt retractor according to any one of the preceding claims,

-at least one force transmission device (9, 10) is provided, which transmits a drive movement from the drive module (20) via the structural interface to the belt reel (2) of the belt reel module (1).

11. The seatbelt retractor according to claim 10,

-the force transmission means (9, 10) are flexible in themselves.
