Inertial sensors
First Claim
1. A sensor responsive to a predetermined level of acceleration force or deceleration force acting on an associated structure when said sensor is properly mounted to said structure, said sensor comprising:
- a linearly movable mass including a first section;
firing means including a firing element for actuation of a mechanism;
means urging said first section into operative engagement with said firing means;
mounting means for mounting said sensor to said associated structure;
releasable safety interlock means normally preventing said mass from operative engagement with said firing means; and
means for automatically releasing said safety interlock means upon proper mounting of said sensor to said associated structure.

Abstract
The sensor includes a linearly movable mass including two sections and spring means urging one of the sections into operative engagement with means including an actuating element. The sensor also includes means releasably securing the two sections together and means releasing the securing means when the two sections have moved a predetermined distance against the urging of the spring. The two sections may be rollers of a rolamite unit. A flexible band extends around a portion of the two rollers. One example of a use for such a sensor is in an air bag safety restraint system.

16. A mechanical sensor without any source of electrical power responsive to deceleration for actuating a pyrotechnic device, said sensor comprising:
-
a movable mass; spring means urging the mass in one direction, deceleration causing said mass to move against the urging of the spring means; and means associated with said mass for actuating the pyrotechnic device in response to the urging of the spring means. - View Dependent Claims (17, 18)
