Abstract
A roller band sensor includes a housing having a cavity including a pair of spaced generally parallel side walls joined by proximal and distal end walls. A pair of bands of flexible spring material within the housing cavity are of generally elongate shape, with their adjacent abutting portions commonly secured to each other and their respective remote portions bearing against and secured to a respective side wall to divide each band into forward and rearward end loops. The forward end loops each include symmetrical shape tapered sections contiguous the secured remote portions and the rearward end loops each include symmetrical shape tapered sections contiguous their secured adjacent portions to obtain a predetermined spring rate and preload normally locating the bands in a preload position unless the bands are subjected to a predetermined velocity or acceleration change whereupon the bands concurrently roll relative to each other and along their respective side walls toward the distal end wall and into bridging engagement with contact structure.
