ABSTRACT:
A G-seat for simulating accelerations is provided with apparatus for generating skin tension/contraction cues. These cues are generated by displacing at least a portion of a body-supporting, seat cushion surface in a direction generally parallel to said surface. Disclosed are various exemplary mechanisms for producing this displacement including apparatus for imparting coplanar movement to either a whole seat cushion, or a section thereof, relative to the remainder of the seat; seat cushion lip extenders; and driveable seat upholstery. The operation of the skin tension cue generator is preferably coordinated with the operation of the other active elements of an Advanced G Seat to produce compatible skeletal attitude, flesh pressure gradient, area of contact and skin tension cues.
