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 shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

Abstract: A fabric assembly includes a knitted fabric and a filament. The knitted fabric is adapted to move between a stretched state extended along a direction of an applied force, and a relaxed state. The filament is disposed in the knitted fabric, and includes a plurality of loops longitudinally spaced apart from one-another. Each loop of the plurality of loops are adapted to project outward from the knitted fabric when in the stretched state, and substantially retract into the knitted fabric when in the relaxed state.

Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

Abstract: Presented are deployable structures having multi-stable-state characteristics using skeletal architectures mounted onto textile backings, methods for making/using such structures, and vehicle components having bistable characteristics provided by polymeric exoskeletons printed onto textile substrates. A multi-stable-state deployable structure includes an elastic substrate fabricated from a (knitted) textile sheet, and an articulating (polymeric) framework mounted on the knitted textile sheet. The articulating framework and textile sheet structurally cooperate to transition from a first stable state, in which the deployable structure maintains a substantially planar shape, to a second stable state, in which the deployable structure maintains a first multidimensional topography, and from the second state to a third stable state, in which the deployable structure maintains a second multidimensional topography distinct from the first multidimensional topography. The articulating framework may include an elongated spine sandwiched between first and second sets of ribs, and a frame circumscribing the spine and ribs.

Abstract: A motion sickness mitigation device includes a textile material having a first surface, a second surface disposed opposite the first surface, and a first raised portion extending from the first surface and configured for contacting a skin of a user. The textile material defines a first pocket and a second pocket therein between the first surface and the second surface, and the second pocket is spaced apart from the first pocket. The device further includes a controller disposed within the first pocket and configured for transmitting an electrical signal. The device also includes a first electrical excitation pad disposed within the second pocket, covered by the first raised portion, and disposed in electrical communication with the controller. The first electrical excitation pad is configured for receiving the electrical signal and electrically stimulating the skin of the user through the textile material to thereby mitigate motion sickness.

Abstract: A conditioned apparatus defines a chamber, and includes a frame defining a door opening providing access to the insulated chamber and a door movable relative to the frame. The door selectively blocks the door opening. A seal disposed between the frame and the door, and a shape memory alloy (SMA) element is associated with, and may be knitted directly into, the seal. A controller operatively connected to the SMA element. The controller selectively provides heat to the SMA element, such that the seal changes from spanning between the door and the frame, when the temperature of the SMA element is below a phase-change temperature, to contacting only one of the frame and the door, when the temperature of the SMA element is at least the phase-change temperature.
