Abstract

A multidirectional sensor for a passive restraint system for a vehicle. The sensor includes a housing and a mass in the form of a disk located in a cavity defined within the housing. The disk is free to move in the cavity from an initial position to one of a number of actuation positions under the influence of a "g" force created in a collision situation. The sensor acts as a switch in an electrical circuit. The switch is open when the disk is in the initial position and closed when the disk is in one of the actuation positions. A spring is secured to the disk to retain the disk in the initial position and resist movement of the disk to one of the actuation positions. The spring is designed and arranged so that, in any direction of movement of the disk, the resultant or composite movement of the spring mass is in the same general direction as the movement of the disk so that the time it takes the disk to move to one actuation position is relatively equivalent to the time it takes the disk to move to any other actuation position. In the preferred embodiment, the spring comprises a thin metal band prestressed to wind upon itself the band is wound around the periphery of the disk with its free end anchored to the housing so that the disk is normally held against a suitable backing surface by the band. In a collision situation, the disc, during movement to an actuation position, rotates and partially unwinds itself from the band.
