Abstract
A seat pan for an automobile vehicle includes a frame carrying a suspension lattice having two sections separated by a vertical median plane dividing the seat into right and left hand sides. A motor and crankshaft combination is connected to each section of the lattice for generating in each section of the lattice a cyclic movement including, in the upper portion of its travel, a rearward movement of translation. The cyclic movements of the sections occur with an angular phase difference therebetween.
