ABSTRACT:
A hydrostatic weight sensor incorporates a load distributor to prevent the bladder of the hydrostatic weight sensor from bottoming out under the influence of applied loads of sufficient concentration and magnitude. The load distributor comprises a flexible mat proximate a load bearing surface of the hydrostatic weight sensor, wherein the flexible mat may be constructed from slitted, punched, pierced, or expanded semi-rigid sheet, a multi-layer plurality of such sheets, or a woven assembly of a plurality of semi-rigid strips. The load distributor is sufficiently flexible to not interfere with seating comfort, yet sufficiently stiff to prevent the bladder of the hydrostatic weight sensor from bottoming out as a result of concentrated loading.
