Abstract: 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.

Abstract: To provide a seat adjustment device capable of flexibly changing a shape of a seat. A seat adjustment device for adjusting a shape of a seat includes a pad including an elastomer, and airbags disposed on a front surface and a rear surface of the pad. The airbags are adjustable in amount of air therein. The airbags include a first airbag disposed on one of the front and rear surfaces and of the pad, and a second airbag disposed on the other. The first airbag is longer than the second airbag in a direction substantially perpendicular to the front and rear surfaces of the pad. The second airbag is longer than the first airbag in a direction substantially parallel to the front and rear surfaces of the pad.

Abstract: A seat back includes: a top-surface seat cover disposed on the top surface; a top-surface cushion pad arranged on a back side of the top-surface seat cover; a contact-surface seat cover disposed on the contact surface; a contact-surface cushion pad arranged on a back side of the contact-surface seat cover and under the top-surface cushion pad; and an airbag having adjustable internal air volume, wherein a lower end portion of the top-surface seat cover is fixed to a first anchorage within the seat back, while covering a lower surface of the top-surface cushion pad, and an upper end portion of the contact-surface seat cover is fixed to a second anchorage within the seat back, while covering an upper surface of the contact-surface cushion pad.
