| 摘要 |
The invention relates to a device for detecting angular acceleration comprising a frame (14) which is rotatable about a rotation axis (16), an output member (18) which is mobile relative to the frame from a non-detection position to a detection position, first means (46) for blocking the output member engaging with mobile means (24) so as to define a maximum angular travel of the chassis (14) during which the output member (18) is capable of moving from the non-detection position to the detection position, and second means (52, 60a, 60b) for blocking the output member (18) configured such as to authorise, under the effect of a centrifugal force (F2) generated by a rotation of the frame (14), a movement of the output member (18) from the non-detection position to the detection position. |
