Problems solved by technology

The reason for this is that the sensor housing can follow the pivoting to a small extent when an acceleration acts in the pivotable direction until it is locked, so that the inertial mass is therefore only deflected to such an extent when the vehicle decelerates significantly. , that is, so that the locking device of the seat belt retractor is actuated

Embodiment Construction

[0022] exist figure 1 and 2 A seatbelt retractor with a self-orienting vehicle acceleration-sensitive sensor device 18 and a sensor housing 1 of the sensor device 18 are shown by way of example. exist figure 2 The middle sensor device 18 is just secured while the seat belt 16 is withdrawn from the belt spool of the seat belt retractor.

[0023] The sensor device 18 comprises a frame fixedly held on the belt retractor, in which the sensor housing 1 is mounted so as to be pivotable about a pivot axis S. The sensor housing 1 also includes a toothing 4 into which a locking lever 19 of a locking device 17 controlled by the direction of rotation of the belt shaft is controlled to engage in order to secure the sensor housing 1 . The sensor housing 1 is released when the belt is wound up on the spool and the locking lever 19 is raised and thus disengaged from the toothing 4 . The sensor housing 1 now orients itself, so that the sensor housing then has an orientation that is optim...

Abstract

The present invention relates to a belt retractor with a self-aligning sensor device (18) sensitive to vehicle accelerations, with a belt shaft which is mounted rotatably in a frame, which is fastenable in a manner fixed on the vehicle, and a first blocking device which is activatable by the sensor device (18) and blocks the belt shaft in the belt extension direction, wherein the sensor device (18) has a sensor housing (1) which is pivotable about a pivot axis (S) and which is securable in relation to the frame by means of a second blocking device (17), wherein a supporting surface (5) on which an inertial mass (20) is mounted is provided in the sensor housing (1), wherein the supporting surface (5) is formed in the sensor housing (1) in such a manner that, when the sensor housing (1) is aligned, the intersecting line between the supporting surface (5) and a first centre plane (E1), which is perpendicular to the pivot axis (S) and runs through the centre of the supporting surface (5), has, from the centre of the supporting surface (5), a shallower angle (W) with respect to a horizontal plane (H) than the intersecting line between the supporting surface (5) and a second centre plane (E2), which is perpendicular to the first centre plane (E1) and runs through the centre of the supporting surface (5).

Description

technical field [0001] The invention relates to a seat belt retractor having the features of the preamble of claim 1 , which has a self-orienting sensor device which is sensitive to vehicle acceleration. Background technique [0002] A sensor device sensitive to vehicle acceleration is usually used to lock the seat belt when a predetermined deceleration or acceleration limit value is exceeded, so that the belt cannot be pulled out from the belt shaft of the seat belt retractor and restrained for the safety of the occupant crew. For this purpose, the sensor device essentially has a spherical or umbrella-shaped inertial mass, which is supported on the mounting or support surface. The response characteristic of the sensor device is determined by the mass of the inertial mass body in the sensor device, the shape of the inertial mass body and the shape of the mounting or supporting surface. In the case of exceeding the deceleration or acceleration limit values ​​specified by th...
