Seat structure

A motor vehicle seat having a backrest and a seat part, at least one flexible, fluid-fillable hollow body attached to the seat part or the backrest, and at least two chambers that are in fluid communication with one another. The chambers are arranged one on top of the other and have in their walls corresponding passages which enable a fluid exchange between the chambers. The chambers are firmly connected to one another in the region of the passages, wherein the volume of the lowermost chamber adjacent to the seat part or the backrest is the largest and the volume of each additional chamber is smaller compared with the volume of the chamber below it. The chambers are arranged one on top of the other such that the maximum lift of the fluid-fillable hollow body when it is being filled with fluid is outside the center of the lowermost chamber.
