Abstract: A seat includes a seat frame, a seating surface supported by the seat frame, and a comfort system disposed between the seat frame and seating surface. The comfort system includes a bladder transitionable between an inflated condition and a deflated condition such that the bladder has a variable size and a variable firmness. The bladder defines a cavity and includes a lower surface adjacent the seat frame, and an upper surface opposite the lower surface and configured to support an occupant of the seat. The comfort system also includes a foam disposed within the cavity, wherein the foam contacts the upper surface when the bladder is in the deflated condition. The comfort system also includes a pump configured for alternately introducing air into the cavity and throughout the foam and removing air from the cavity and the foam to transition the bladder between the inflated condition and the deflated condition.

Abstract: A seat cushion is provided. The seat cushion includes a first cushion comprising a top side and a bottom side. The bottom side or the top side includes a contoured area and the contoured area has a convex or a concave shape.

Abstract: A seat structure is configured to support an occupant. The seat structure includes a suspension. A seat cushion is arranged adjacent to the suspension. The seat cushion defines a plurality of variable effective property regions. At least one of the plurality of variable effective property regions includes a regular periodic lattice structure.

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.
