ABSTRACT:
Relative axial movement of telescopically mounted support members is converted to rotation of an inertia mass by means of a ball-screw arrangement and a capstan spring loosely surrounding a portion of one of the support members. Slow acceleration of the inertia mass is accommodated, but rapid acceleration causes the inertia mass to lag which winds the capstan spring enough to grip one of the support members, which are rotationally fixed, and thereby snub movement until acceleration forces decrease. A spring band clutch positioned within the inertia mass and linked to the capstan spring ends enables the mass to slip in the event high velocity movement of the support members occurs and is then interrupted.
