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.

Abstract: A method for securing sandwich structures together, especially vehicle structures. In one embodiment, two sandwich structures are perpendicularly secured together, where a first one of the sandwich structures includes a micro-truss core having one unit cell geometry and second one of the sandwich structures includes a micro-truss core having different unit cell geometry. The micro-truss core of the second sandwich structure includes a micro-truss extension fabricated at the same time as the micro-truss core and having the same unit cell geometry as the micro-truss core for the first sandwich structure. The extension is inserted in an open area between face sheets in the first sandwich structure so that it abuts against the micro-truss core in the first sandwich structure.

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: An approach to designing lightweight metal-polymer composite structures in a manner that decomposes the structure into at least two parts. In one specific embodiment, the approach is a manufacturing process for a vehicle that includes attaching an impact beam to a vehicle structure. The process includes providing a vehicle structure including a back plate of the impact beam being made of a suitable material, such as a metal, that can withstand high temperature processes. A front part of the impact beam including a front plate and a polymer core is attached to the back plate. The back plate is designed to provide structural integrity that allows the vehicle structure to go through the high temperature processes and/or the vehicle structure provides structural integrity that allows the back plate to go through the one or more processes. The back plate is also designed to provide desired functional characteristics of the beam.
