Abstract: Disclosed herein is a haptic device having at least one vibration motor, such as a linear vibration motor, configured to selectively generate a vibration at least partially along an actuator axis. An interfacing plate is configured to transmit the vibration and is at least partially composed of a compliant material. The linear vibration motor and the interfacing plate are embedded in a host. The host defines a first surface with a recessed zone extending from the first surface. The interfacing plate is configured to fit in the recessed zone. The host includes a chamber contiguous with the recessed zone, with the linear vibration motor being positioned in the chamber. The chamber may include respective walls having a plurality of protrusions configured to at least partially absorb the vibration. The haptic device may be part of a seat assembly.

Abstract: A system for a seat of a vehicle includes a seat cushion, a seat cover, and a valve. The seat cushion forms at least part of a bottom of the seat. The seat cover encloses the seat cushion and forming a barrier to airflow out of the seat cushion. The seat cover forms a top surface of the seat bottom, a bottom surface of the seat bottom, and side surfaces of the seat bottom. The valve extends through the seat cover and is configured to regulate airflow out of the seat cushion through the valve.

Abstract: A knitted structure is configured for heat generation and distribution. In some embodiments, the knitted structure includes a knitted fabric including a first knitted layer and a second knitted layer opposite the first knitted layer. The first knitted layer has a first thermal conductivity. The second knitted layer has a second thermal conductivity. The second thermal conductivity is greater than the first thermal conductivity to facilitate heat transfer toward the first knitted layer. The knitted structure may further include a plurality of electrodes at least partially disposed inside the knitted fabric. Each of the plurality of electrodes is configured to generate heat within the knitted fabric upon receipt of electrical energy in order to distribute heat along the knitted structure and toward the first knitted layer.

Abstract: A seat cushion includes a cushion body defining a first body surface and a second body surface opposite the first body surface, wherein the first body surface is configured to face the seat occupant, and the second body surface is configured to face away from the seat occupant. The cushion body defines a plurality of holes extending into the second body surface or columns extending from the second body surface. The holes or columns are arranged on a pattern to allow the cushion body to passively conform to the seat occupant, thereby enhancing comfort.

Abstract: An inflatable system includes a bladder configured to contain fluid, a first plurality of tethers disposed within a first region of the bladder, and a second plurality of tethers disposed within a second region of the bladder. The first plurality of tethers has a first tether length, a first tether spacing, a first tether angle relative to one wall of the bladder, and a first tether stiffness. The second plurality of tethers has a second tether length, a second tether spacing, a second tether angle relative to the one wall, and a second tether stiffness. At least one of: the second tether length is different than the first tether length; the second tether spacing is different than the first tether spacing; the second tether angle is different than the first tether angle; and the second tether stiffness is different than the first tether stiffness.

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.

Abstract: A fluid bypass valve includes a valve member disposed within a valve chamber of a housing. A temperature based actuating mechanism moves the valve member between a first position and a second position in response to a temperature change. A temporary flow control device undergoes a one-time only shape change between a first shape and a second shape. The temporary flow control device enables fluid communication between a first port and a second port when exhibiting the first shape, and does not enable fluid communication between the first port and the second port when exhibiting the second shape. The temporary flow control device exhibits the first shape when having an initial temperature less than or equal to a second pre-defined temperature, and exhibits the second shape in response to a first heating of the temporary flow control device to a temperature that is greater than the second pre-defined temperature.
