Abstract

The present invention relates to a seat control system for a vehicle. The system includes a substrate with a plurality of touch zones disposed on one surface of the substrate, and a plurality of electrode patterns disposed on the opposite surface. An inner electrode of each pattern is aligned with one of the touch zones. Each pattern is electrically coupled to an active electrical component, which energizes the electrodes of the pattern such that electric fields emanate therefrom. The pattern may be capacitively coupled to the component. When the electric field of the inner electrode is disturbed by a stimulus proximate the corresponding touch zone, the component is activated. Upon activation of one of the components, a controller causes the seat to move in a desired direction.

Claims

1. An ergonomic seat control panel, comprising:

a substrate defining a base portion and a first protruding portion protruding from said base portion, said first protruding portion corresponding to a first movable portion of a seat and said first protruding portion defining a first touch surface in a first location corresponding to a first direction of movement of said first movable portion and a second touch surface in a second location corresponding to a second direction of movement of said first movable portion;

a first touch sensor comprising a first sensing electrode in the form of a thin conductive pad and an outer sensing electrode substantially surrounding said first sensing electrode, said first sensing electrode and said outer sensing electrode in operable association with said first touch surface; and

a second touch sensor comprising a second sensing electrode in operable association with said second touch surface;

wherein at least one of said first and second electrodes comprises a stamped electrode that is insert-molded into said corresponding protruding portion,

wherein introduction of a stimulus proximate said first touch surface causes movement of said first movable portion of said seat in said first direction, and

wherein introduction of a stimulus proximate said second touch surface causes movement of said first movable portion of said seat in said second direction.

2. The control panel of claim 1 wherein each of said first sensing electrode and said outer sensing electrode is coupled to an electrical signal source and receives an electrical signal from said electrical signal source;

wherein an electric field is generated about each of said first sensing electrode and said outer sensing electrode in response to said electrical signal;

wherein introduction of a stimulus proximate said first touch sensor causes movement of said first movable portion only if said stimulus disturbs said electric field about said first sensing electrode to a greater degree than said stimulus disturbs said electric field about said outer sensing electrode.

3. The control panel of claim 1 wherein said first protruding portion is integral with said base portion.

4. The control panel of claim 1 wherein said first protruding portion mimics the shape of said first movable portion.

a fourth touch sensor comprising a fourth sensing electrode, said fourth sensing electrode disposed on said substrate in operable association with said fourth touch surface;

wherein introduction of a stimulus proximate said third touch surface causes movement of said second movable portion of said seat in said first direction, and

wherein introduction of a stimulus proximate said fourth touch surface causes movement of said second movable portion of said seat in said second direction.

16. The control panel of claim 15 wherein said base portion defines a fifth touch surface, said control panel further comprising a fifth touch sensor comprising a fifth sensing electrode, said fifth sensing electrode disposed on said substrate in operable association with said fifth touch surface, said fifth touch sensor corresponding to a controllable function of said seat.
