Abstract
The mechanism automatically cuts a hydraulic pneumatic or electric control system for a vehicle safety belt in or out when a housing tilts through more than a predetermined angle from its normal position or on acceleration or deceleration of the housing. A spherical body (4) is movable freely in an airtight chamber (3) in the housing (1) and normally shut off a port (7) connecting the chamber to atmosphere. A pipe (12) connects the chamber to a pressure or vacuum source and a second pipe (13) from the chamber is closed at the other end by a control member (14) sliding in the pipe against spring action (15). Tilting or inertia causes the body to uncover the port, whereupon the vacuum or pressure in the chamber collapses and allows the spring to move the control member.
