Abstract
A vehicle sensor for a retractor for a vehicle safety restraint has a sensor mass in the form of an upturned hollow cup, formed in a single piece by injection molding or die casting, resting on an upstanding post. It may be of metal or high-density plastic material. Preferably a profiled pad is fixed or mounded on the underside of the lever or on the upper surface of the cup. In this way the arrangement causes the lever to lift through substantially the same angle whichever the direction of acceleration activating the sensor. This sensor is an improvement over known sensors because it is simpler and cheaper to manufacture, easier to calibrate relatively accurately, and does not exhibit right/left dependency.
