Abstract: An apparatus is disclosed for adjusting an active length of a plurality of interwoven support elements of a weight bearing surface to conform to contours of a user's anatomy. The weight bearing surface overlies a frame to which the plurality of interwoven support elements are connected. The apparatus includes an adjustment mechanism connected to one of the plurality of interwoven support elements, wherein the adjustment mechanism is attached or releasably attached to the frame. The adjustment mechanism allows the active length of the connected interwoven support element to change as a user bears upon the weight bearing surface, thereby conforming the weight bearing surface to the contours of a user's anatomy. In another aspect, a method for adjusting an active length of at least some of a plurality of interwoven support elements of a weight bearing surface to conform to contours of a user's anatomy is disclosed.

Abstract: A substantially smooth, seamless managed friction material surface and apparatus for placement on a support surface between the support surface and a living being for preventing abrasion or decubitus ulcers in a living being. The managed friction material surface comprises a plurality of plies having a smooth side and a first, high friction zone and second, low friction zone. At least one adhesive ply is interposed partially between adjacent plies; and the plies are selectively bonded to form adjacent frictional zones of high and low friction. Unbonded plies are allowed to move substantially freely with respect to one another thus providing a lower friction zone. The apparatus comprises the managed friction material surface such that the bonded zone is configured for positioning remote the bony prominence and the unbonded zone for positioning proximate the bony prominence, seamlessly occupying different areas on the same side of the material surface.

Abstract: An apparatus is disclosed for placement on a support surface between the support surface and a living being, wherein the living being has a bony prominence. The apparatus includes a first zone having a first coefficient of friction, the first zone being configured for positioning proximate the bony prominence. A second zone is adjacent the first zone, the second zone having a second coefficient of friction higher than the first coefficient of friction. The second zone is configured for positioning remote from the bony prominence. A method of preventing or healing decubitus ulcers includes positioning the bony prominence over the first zone and positioning an area remote from the bony prominence over the second zone.

Abstract: A brake mechanism includes an input, a chassis, a lock and a release mechanism. The input is an axially extending input having first and second ends. The chassis interfaces with the input such that the input is movable relative to the chassis. The lock is coupled to the chassis for constraining movement of the input relative to the lock. The release mechanism is coupled to the lock and is responsive to a force applied relative to the input and the chassis such that when the force is greater than a release force level the release mechanism allows the lock to disengage the input and such that when the force is less than the release force level the release mechanism does not allow the lock to disengage the input.
