Abstract
In an acceleration sensor for use in an automobile seatbelt system comprising a rolling body which moves when subjected to an acceleration, a cup-like receptacle member for supporting the rolling body on a sloping surface rising towards an outer periphery of the receptacle member, and a pivotally mounted actuator over the rolling body for triggering a web halting mechanism, wherein the sloping surface is formed with a plurality of radially disposed ribs, so that the rolling body is prevented from rolling around the sloping surface even when subjected to vibration from rough roads. The invention prevents the web belting mechanism from being triggered spuriously without diminishing the sensitivity of the acceleration sensor in a bona fide vehicular emergency situation.
