Abstract: A motor vehicle seat has a seat inflation system for selectively inflating/deflating a plurality of inflatable cushions in the seat back and/or bottom. A switch for controlling the system includes a display having a first symbol indicating a function of the cushion and a second symbol indicating a parameter of the active function, a plurality of keypads defining a circular perimeter surrounding the display and actuatable to select the active function, and a ring surrounding the perimeter and rotatable to adjust a value of the parameter.

Abstract: A system and method for controlling and selecting massage operations of a motor vehicle seat having a plurality of inflatable cushions and a control system controlling inflation of the cushions to perform a massage function. A touch-screen display is used to make inputs to the control system. The display is calibrated as a two-dimensional coordinate system on which are displayed pictograms representing a plurality of massage function blocks. To create or generate a massage program to be performed by the controller/seat, an operator drags-and-drops the pictograms on the display to respective positions in the coordinate system, thereby adjusting respective settings of two parameters of the massage function, the coordinate of the pictograms in each coordinate axis corresponding to one of the respective parameters.
