An acceleration sensor for a motor vehicle comprises a platform (24) which is pivotally mounted (25) and which supports a pendulum member (28) which has an enlarged head (32) resting on the platform and a shaft (29) extending through an aperture in the platform, the shaft carrying an inertia mass (30) at its lower end. An operating lever (20) is provided resting on top of the head (31) of the pendulum member (28). A blocking member is provided which is pivotally mounted (34) and which has an inertia mass (37) and forwardly projecting arms (38, 39). On deceleration of the vehicle in excess of a predetermined limit one arm (39) of the blocking member (33) engages the platform (24) and the pendulum member (28) then pivots about a point where the periphery of the head (31) rests on the platform (24) causing the lever (20) to rise.
