Abstract:
1. A seat, comprising: an adjustable first seat component; an adjustable second seat component coupled to said first seat component; first and second actuating means for adjusting positions of said first and second seat components, respectively, when actuated; and monitoring means for monitoring collision-establishing edge geometries of said first and second seat components with assigned first and second three-dimensional boundaries, respectively, at all times during adjustment movements to ensure collision-free motion of said first and second seat components within said three-dimensional boundaries relative to adjacent objects, said three-dimensional boundaries being defined at least partially by boundary curves dividing seat spaces from one another and forming an envelope space, said seat components being movable dependent on one another within said envelope space, said monitoring means controlling all intended motions of said first and second seat components in combination by a mathematical algorithm in a common imaginary envelope curve with edges to prevent collisions at least partially defined by said boundary curves, said mathematical algorithm having equations of straight lines, the number of said equations being increased to form a closed three-dimensional envelope curve defining said envelope space.
