A seat belt retractor including a self-directed vehicle acceleration sensor device

摘要

The present invention relates to a belt device comprising a belt shaft rotatably supported on a frame that can be mounted in a fixed manner relative to a vehicle and a first block device for blocking the belt shaft in a belt withdrawing direction, Comprising a self-oriented vehicle acceleration-sensitive sensor device (18) including a blocking device, the device being controllable by a device (18), the sensor device (18) comprising a centering pivot Wherein the sensor housing comprises a sensor housing pivotable in a sensor housing and the sensor housing is fixable to the frame using a second blocking device, In the case of a sensor housing (1) oriented in a belt retractor in which the inertial mass (20) is supported on this contact surface (5), starting from the center of the contact surface (5) The intersection line between the contact surface (5) and the first center plane (E1) extending through the center of the contact surface (5) perpendicular to the pivot axis (S) is formed by the contact surface (5) (H) with respect to the horizontal plane (H) than the line of intersection between the second center plane (E 2) extending through the center of the contact face (5) perpendicular to the center plane (E 1) The contact surface (5) of the sensor housing (1) is formed so as to have a width (W).BACKGROUND OF THE INVENTION
