Abstract: A belt retractor including a self-orienting vehicle-acceleration-sensitive sensor device (18) including a belt shaft, and a first blocking device blocking the belt shaft in the belt extraction direction, which is controllable by the sensor device (18). The sensor device (18) includes a sensor housing (1) pivotable about a pivot axis (S), which is fixable with respect to the frame using a second blocking device (17). A contact surface (5) for an inertial mass is provided in the sensor housing (1). The contact surface (5) is shaped such that in the case of an oriented sensor housing (1) starting from the center of the contact surface (5), the line of intersection between the contact surface (5) and a first central plane (E1) extending through the center of the contact surface (5) perpendicular to the pivot axis (S) has a flatter angle (W) with respect to the horizontal plane (H) than the line of intersection between the contact surface (5) and a second central plane (E2) extending through the center of the contact surface (5) perpendicular to the first central plane (E1).
