Abstract: An anti-submarining seat cushion for a vehicle includes a main body constructed of an anisotropic material. The anisotropic material includes a primary material including a primary stiffness and a plurality of inserts that are dispersed throughout the primary material. The plurality of inserts exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, where the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.

Abstract: A structural component for a vehicle includes a component including an interior surface defining a first hollow passage and a structural reinforcement contacting the interior surface of the component. The structural reinforcement and component define a cross-section and the structural reinforcement partially fills the cross-section. A process for forming the structural component including inserting a bladder into the first hollow passage defined by the interior surface of the component and inflating the bladder in the first hollow passage, forming a cavity between the bladder and the interior surface, filling the cavity with a polymer resin, and foaming the polymer resin. A system for forming a structural component for a vehicle includes a component including a first hollow passage defined by an interior surface of the component, a bladder insertable into the first hollow passage of the component, and a supply line connected to an interior of the bladder.

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 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: An energy absorbing structure includes a base, a loading platform, a pair of side supports, a center support, and a pair of flexible segments. The loading platform is spaced apart from the base. The side supports project from the base toward the loading platform. The center support projects from the loading platform toward the base. The flexible segments extend from the side supports to the center support and connect the side supports to the center support. The flexible segments have straight edges and curved surfaces disposed between the straight edges. The straight edges extend from the side supports to the center support and are oriented at an oblique angle relative to the base. Each of the curved surfaces faces one of the base and the loading platform.

Abstract: An electric motor includes a rotor having a stack of laminations positioned axially relative to one another. The stack of laminations includes a first rotor lamination that is divided into a first portion and a second portion. The first rotor lamination is configured to have an asymmetric mass distribution such that the first portion has a first mass and the second portion has a second mass, with the first mass being different from the second mass. The electric motor is configured to selectively generate an unbalanced force during operation (i.e., when the rotor is spinning). The electric motor may include a stator configured to have an asymmetric magnetic field distribution. The electric motor may be employed in a haptic assembly and eliminates the need for a separate eccentric mass to generate a haptic signal.

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 method for fabricating a micro-truss structure having particular application for a vehicle impact structure. The method includes providing a thin support enclosure having a plurality of walls, where at least one of the walls is transparent to ultraviolet (UV) light. The support enclosure is filled with a liquid photomonomer resin and light from at least one UV source is directed through apertures in a mask and through the at least one transparent wall into the enclosure so as to polymerize and at least partially cure columns of the resin therein to form polymerized struts defining a micro-truss core in the enclosure that is secured to the walls. The support enclosure is then inserted into an outer structural enclosure.

Abstract: A three-dimensional lattice includes a stabilizing grid having grid warp strands and grid weft strands crossing the grid warp strands. Grid cells are defined by adjacent grid warp strands and adjacent grid weft strands intersecting the adjacent grid warp strands. A projecting net has net warp strands and net weft strands crossing the net warp strands. Each subnet in a plurality of subnets uniquely corresponds to a corresponding grid cell. Each subnet includes a net warp strand portion intersecting both of the grid weft strands that define the corresponding grid cell. Each subnet includes a net weft strand portion intersecting both of the grid warp strands that define the corresponding grid cell. The net warp strand portion and the net weft strand portion of each subnet are spaced from a minimum surface defined by the corresponding grid cell.
