Abstract: An extensively reconfigurable seat design can include a vehicle seat system including: a vehicle seat defining a vehicle occupant accommodating space, the vehicle seat including a seat cushion portion including multiple individually adjustable bladders, where each of the multiple individually adjustable bladders has a connected valve that controls fluid communication with an internal space of the individually adjustable bladder to adjust a pressure level within the internal space of the individually adjustable bladder, and an associated sensor configured to detect the pressure level within the internal space of the individually adjustable bladder. A computer can actively sense and control the pressure levels within the bladders, using the sensors and valves, to provide customization, adaptive, ride-active and intelligent control over a reconfigurable cushion for a vehicle.

Abstract: A computer-implemented method of generating one or more variable stiffness structures includes determining a thickness of a first portion of a variable stiffness structure; determining a pressure that is to be applied to a surface of the first portion; selecting a first predetermined value for a stiffness attribute based on the thickness of the first portion and the pressure; and generating a model of at least part of the variable stiffness structure that includes the first portion, wherein the first portion has the predetermined value for the stiffness attribute.
