Abstract: Cargo systems are provided for vehicles that include, in one embodiment: a variable cargo surface disposed within a body of the vehicle behind one or more occupant seats, the variable cargo surface including: a low friction surface that facilitates movement of cargo within the cargo system, the low friction surface having a first coefficient of friction; a high friction surface that inhibits movement of cargo within the cargo system, the high friction surface having a second coefficient of friction that is greater than the first coefficient of friction; and a control device that selectively activates the low friction surface and the high friction surface based on conditions for the vehicle; wherein the low friction surface contacts the cargo within the cargo system when the low friction surface is activated; and the high friction surface contacts the cargo within the cargo system when the high friction surface is activated.

Abstract: A vehicle seat includes a first knitted fabric layer defining an outer surface and a second knitted fabric layer defining an inner surface. The inner surface is opposite the outer surface. The vehicle seat further includes a knitted spacer fabric interconnecting the first knitted fabric layer and the second knitted fabric layer. The knitted spacer fabric resiliently biases the first knitted fabric layer and the second knitted fabric layer away from one another. The knitted spacer fabric is configured to buckle when a seated occupant exerts an occupant load on the vehicle seat. The first knitted fabric layer is more elastic than the second knitted fabric layer to conform to the seated occupant when the seated occupant exerts the occupant load on the vehicle seat.

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: An inflatable system includes a first bladder configured to contain gas and a second bladder configured to contain gas. The first bladder includes a top wall, a bottom wall opposite of the top wall, a sidewall extending between and connected to perimeter edges of the top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of the top and bottom walls. The second bladder includes a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls. The bottom wall of the first bladder is secured to the top wall of the second bladder.

Abstract: Systems and methods are provided for gripping of a workpiece with a layer jamming structure having rigid datum structures. A system includes a layer jamming structure configurable in an inactivated conformable state, with a membrane defining an internal cavity containing a number of overlapping material layers. The rigid structures engage the layer jamming structure. A pressure system includes a pump coupled with the internal cavity to change a pressure therein to transform the layer jamming structure from the inactivated conformable state to an activated rigid state disposed around the workpiece. The rigid structures help conform the layer jamming structure to the workpiece during transformation to the activated rigid state and to present datum fixturing surfaces in the activated rigid state.

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.
