Abstract: A structural component for a vehicle and a process and system for forming the structural component. A first cavity is formed in a first hollow passage between a first bladder and an interior surface of a component forming the structural component. A first structural reinforcement layer is formed in the first cavity by filling the first cavity with a first polymer resin and foaming the first polymer resin to form a first polymer resin foam. A second cavity is formed in the first hollow passage and a second structural reinforcement layer is formed in the second cavity by filling the second cavity with a second polymer resin and foaming the second polymer resin to form a second polymer resin foam.

Abstract: A system for de-emphasizing fixed vehicle-mounted objects within a rear camera display includes a rear camera system adapted to capture images as the vehicle moves in reverse and display the captured images on the rear camera display, and a data processor in communication with the rear camera system and the rear camera display and adapted to collect sequential images captured by the rear camera system, compare the plurality of sequential images, identify fixed vehicle-mounted objects within the sequential images, calculate a portion of the sequential images that are obscured by identified fixed-vehicle objects, and, when the portion of the sequential images that are obscured by identified fixed-vehicle objects lies within a pre-determined range, to outline the identified fixed vehicle-mounted objects within the rear camera display, and augment the identified fixed vehicle-mounted objects.

Abstract: A vehicle, suspension system and method of dampening a force on the suspension system is disclosed. The suspension system includes a damper having a first damping element and a second damping element configured to rotate relative to each other in response to a force received at the suspension system. The second damping element induces an eddy current in the first damping element during relative rotation. A feature of one at least one of the first damping element and the second damping element provides a first electrical resistance to the eddy current during relative rotation in a first direction and a second electrical resistance to the eddy current during relative rotation in a second direction. The first electrical resistance generates a first damping force and the second electrical resistance generates a second damping force.

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 vehicle hood covering an underhood object includes an inner surface of the vehicle hood facing the underhood object and spaced from the underhood object, and an outer surface of the vehicle hood opposite the inner surface. A local energy absorber is operatively attached to the inner surface of the vehicle hood. The local energy absorber is a multiply-connected structure. The local energy absorber includes a wall defining an interior surface having symmetry about a central plane normal to the inner surface of the vehicle hood. A plurality of apertures is defined in the wall symmetrically about the central plane to initiate buckling and fracture in the wall during an impact applied to the outer surface defining an impact event having a duration of less than 20 milliseconds.

Abstract: Products and methods are provided for inflatable structures. In various exemplary embodiments, an inflatable structure is provided with multiple variable chambers including a first variable chamber and a second variable chamber. A first boundary envelope defines the first variable chamber and a second boundary envelope defines the second variable chamber. The first and second boundary envelopes separate the first chamber from the second chamber. The first and second variable chambers are defined by an operative scale that may differ by an order of magnitude between the first and second variable chambers.

Abstract: A suspension member for a seat assembly includes a plurality of zones which define spatially varying properties of the suspension member. Each of the zones produces a response to an occupant load imposed on the seat assembly by a seated occupant, where the response includes one or more of a stiffness response, an energy dissipation response, and a thermal response. The response produced by each zone is different from the response produced from any other of the zones. The suspension member can be made of a homogenous material or made of a combination of materials such that each zone is made of a different material. The suspension member can include a textile material formed by weaving, knitting or crocheting. At least one zone of the suspension member can include one or more apertures.

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 support assembly formed by an additive manufacturing process using a printing head includes a trim member. A body includes multiple layers of at least one polymeric material applied onto the trim member via the printing head. The multiple layers each have multiple resilient polymeric material elements. A protective and abrasion resistant polymeric material cover is applied over the body using the printing head. At least one structural element is positioned in the body by operation of the printing head. At least one sensor is positioned in the body. At least one passage is formed within the body by selective omission of the at least one polymeric material from the printing head as the printing head displaces during the additive manufacturing process.
