Abstract
A holding mechanism for a vehicular acceleration sensor, comprising: a pair of lever arms operable to move independently of one another; and an inertia weight held between the lever arms, wherein movement of the inertia weight, in use, when under acceleration, causes at least a part of at least one lever arm or both arms to move in a generally linear direction.
Claims21
An acceleration sensor comprising:
- a holding mechanism having a pair of lever arms operable to move independently of one another;
- and
- an inertia weight held between the lever arms, wherein movement of the inertia weight, in use, when under acceleration, causes at least one lever arm to move;
- and
- a trip mechanism rotatably mounted adjacent to the lever arm to engage the moving lever arm and, in response to the lever arm movement, convert the lever arm movement into a rotational movement of the trip mechanism about an axis, which rotational movement is detectable as an output of the sensor indicating acceleration of the inertia weight.
2 more elements
An acceleration sensor comprising
- an inertia weight located supported at a first end of a lever arm which is mounted for pivotal movement about a second end of the lever arm and movable in a generally linear direction in response to movement of the inertia weight,
- a trip mechanism rotatably mounted adjacent to the inertia weight so that movement of the inertia weight supported at the first end of the lever arm causes contact with the trip mechanism to convert lever arm movement into rotational movement of the trip mechanism, which rotation of the trip mechanism is detectable as an output of the sensor.
