A self-locking seat-belt retractor for a vehicle has a U-shaped seat belt retractor frame (2) with two opposite frame pieces (2a, 2b) each with an opening (2c, 2d), in which a belt shaft (1) is rotatably mounted. A sensor device (3) is configured to actuate a locking device (4) to lock the belt shaft (1) if a predetermined vehicle deceleration is exceeded. A mass (6) is supported in a housing of the sensor device. The sensor device (3) with the housing (9) is held in a support element (7) mounted on the frame piece (2a) of the seat belt retractor frame (2). The support element (7) protrudes into an opening 25 on the frame piece (21) from one side with a portion receiving the sensor device (3). A cover element (11) closes the opening (25) from the other side of the frame piece (2a). |
