Abstract: A vehicle seat assembly is provided with a seat back and a head restraint assembly supported by the seat back. The head restraint assembly has a substrate with a main body extending from a transverse mounting surface to an upper edge of the head restraint assembly, and a projection extending downwardly from the mounting surface of the main body to a lower end of the head restraint assembly. The main body and the projection cooperating to define a continuous support surface for an occupant. A first massage element and a second massage element are supported by the projection. The first and second massage elements and the lower end of the head restraint assembly are positioned between the mounting surface and the lower end of the head restraint assembly. A head restraint assembly and a method of controlling a vehicle seat assembly are also provided.

Abstract: A seat assembly with an adjustable head restraint assembly capable of being adjusted based on an approximate stature or spatial location of an occupant in the seat assembly. A seat assembly may include a sensor in the seat to detect if an occupant is present. The sensor may include a plurality of bladders and pressure sensors, a radar system, or a neuro-monitoring sensor. The sensor may send a signal to a controller indicating the presence of an occupant. The controller may approximate the size and/or spatial location of the occupant and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to an in-use position. The controller may determine that an occupant is not present and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to a non-use position.

Abstract: A method for manufacturing a seat cushion receives data of a specific occupant. A seat cushion is designed from the occupant data. The seat cushion is provided with a cellular structure from the occupant data. Another method for manufacturing a seat cushion receives boundary conditions for a seat cushion. Applicable mechanical properties are determined for the boundary conditions of the seat cushion. Applicable thermal properties are determined for the boundary conditions of the seat cushion. A seat cushion is designed with a varying cellular structure to satisfy the applicable mechanical properties and the applicable thermal properties.
