Abstract: A cushion member having improved variable stiffness for a target is provided. The cushion member comprises a cushion housing having an interior with a variable internal pressure and an exterior surface for receiving the target. The cushion housing is arranged to be deformable and comprises granular particles disposed in the interior of the cushion housing. The cushion housing further comprises hollow particles disposed therein with the granular particles. Each hollow particle is compressible and hollow to define a void therein. The hollow particles have a size, a wall thickness, a material, and a bulk modulus defining infill properties thereof. The hollow particles and the granular particles are arranged to allow the cushion housing to be deformed upon contact with the target. The hollow particles and granular particles define a cushion infill having a variable stiffness based on the infill properties and the variable internal pressure of the interior.

Abstract: A lightweight and portable inflatable assembly includes an inflatable structural component and a chemical reaction based inflator device. The inflatable structural component includes a flexible housing defining a cavity. The inflatable structure is uninflated in a first operational mode and filled with an inflation fluid retained for at least 4 hours in a second operational mode. At least one primary and at least one secondary charge unit are in fluid communication with the cavity. The primary charge unit includes a first gas generant material configured to generate a first predetermined volume of inflation medium for filling the cavity, while the secondary charge unit includes a second gas generant material configured to generate a second predetermined volume of inflation medium for filling the cavity in the second operational mode. The second predetermined volume is ≤about 40% by volume of the first predetermined volume.

Abstract: A cover covering an object includes an inner surface of the cover facing the object and spaced from the object, and an outer surface of the cover opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the cover. The local energy absorber includes an energy absorbing core layer operatively attached to the inner surface of the cover and a frangible face sheet layer attached to the energy absorbing core layer facing the object. The frangible face sheet layer is to initiate fracture of the frangible face sheet layer during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.

Abstract: A structural member includes an inflatable bladder. The structural member may include a fabric shell disposed about an exterior surface of the bladder, or a spacer element attached to an interior surface of the bladder. The fabric shell or spacer element restrains the shape of the bladder to contour the bladder into a desired shape and increase the load carrying capacity of the bladder.

Abstract: An occupant support structure and a method of customizing an occupant support structure. The occupant support structure may comprise a base and a reconfigurable cushion carried by the base. The reconfigurable cushion may include an occupant support surface and a bladder. The bladder may include an outer wall that defines an inner cavity underlying the occupant support surface and two or more overlapping material layers disposed within the cavity. The overlapping material layers may be adapted to selectively transition from a compliant state to a rigid state and vice versa by selective control of a pressure condition across the outer wall of the bladder to reconfigure or conform the occupant support surface of the cushion to a contour of a portion of an occupant supported by the cushion.

Abstract: A seat assembly for supporting an occupant of a vehicle includes a cushion and a suspension. The cushion has a first surface and a second surface. The first surface is configured to engage the occupant. The second surface is disposed opposite the first surface. The suspension includes a first portion and a second portion. The first portion includes a third surface. The third surface engages the second surface of the cushion. The second portion includes a fourth surface. The fourth surface defines a first depression. The first depression opens toward the cushion. The first depression is configured to receive a portion of the cushion when the occupant exerts a load on the cushion.
