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.

A seat pan, for an automobile vehicle, comprising:
- a frame carrying a suspension lattice having two sections separated by a vertical median plane dividing a seat into right and left hand sides;
- means connected to each of the sectors of the lattice for generating in each of the sectors of the lattice a cyclic movement including, in an upper portion of its travel, a rearward movement of translation;
- control means for generating said movement with an angular phase difference between the two sections;
- and
- pressure sensors being positioned under the surface of the seat pan such that they can measure the pressure exerted on the seat pan surface at a minimum of two points situated one in front of the other.
