Abstract

Acceleration initiated, velocity limiting self-actuating mechanical relative motion, controlling device having a pair of elements telescopically interconnected for relative motion with respect to each other with a braking surface preferably as an integral part of one of the elements and an interconnecting assembly for converting linear relative displacements of the elements to rotary motion of the internally supported braking mechanism comprising a primary brake assembly preferably coupled to increase mechanical gain and movable into engagement with the braking surface, a freely rotating first mass element to provide relative motion sensitivity, a brake actuating assembly coupling the mass element and the primary brake assembly for causing same to impede relative linear motion of the elements and a velocity sensitive braking assembly actuatable at a given angular velocity to impede rotation of the same element and thereby increase and sustain the braking force applied by the primary brake assembly. The preferred embodiment also includes a secondary mass element rotatably supported on the first mass element for movement with respect to same for prolonging the application of the brak…
