Vehicle seat and method for cushioning two spring parts which are movable relative to each other
First Claim
1. A vehicle seat having a seat part extending in a vehicle length direction (X) and in a vehicle width direction (Y) and having a backrest part and a seat substructure for cushioning and/or damping at least the seat part with respect to a body of a vehicle, in which the seat substructure comprises at least one horizontal spring device having a first spring part, and a second spring part which is movable relative thereto and a deformable fluid spring element for cushioning the seat part with respect to the body in the vehicle length direction (X) and/or in the vehicle width direction (Y), the deformable fluid spring element being arranged with a first connecting region to the first spring part and a second connecting region to the second spring part, wherein the deformable fluid spring element is arranged between the first and second spring parts so as to be deformed solely by the first and second spring parts upon relative movement of the first and second spring parts relative to each other along the at least one of the vehicle length direction (X) and the vehicle width direction (Y), wherein the deformable fluid spring element is subjected to shear forces by the movement of the first and second spring parts relative to each other, and wherein the deformable spring element resists the shear forces.

Abstract
A vehicle seat having a seat part extending in the vehicle lengthwise direction (X) and in the vehicle width direction (Y) and having a backrest part and a seat substructure for cushioning and/or damping at least the seat part with respect to a body of a vehicle, in which the seat substructure comprises at least one horizontal spring device having a first spring part and a second spring part that is movable relative thereto and a deformable fluid spring element for cushioning the seat part with respect to the body in the vehicle lengthwise direction (X) and/or in the vehicle width direction (Y), the deformable fluid spring element being arranged with a first connecting region to the first spring part and a second connecting region to the second spring part, wherein the deformable fluid spring element is arranged between the first and second spring parts so as to be deformed solely by the first and second spring parts upon relative movement of the first and second spring parts relative to each other.

- 1. A vehicle seat having a seat part extending in a vehicle length direction (X) and in a vehicle width direction (Y) and having a backrest part and a seat substructure for cushioning and/or damping at least the seat part with respect to a body of a vehicle, in which the seat substructure comprises at least one horizontal spring device having a first spring part, and a second spring part which is movable relative thereto and a deformable fluid spring element for cushioning the seat part with respect to the body in the vehicle length direction (X) and/or in the vehicle width direction (Y), the deformable fluid spring element being arranged with a first connecting region to the first spring part and a second connecting region to the second spring part, wherein the deformable fluid spring element is arranged between the first and second spring parts so as to be deformed solely by the first and second spring parts upon relative movement of the first and second spring parts relative to each other along the at least one of the vehicle length direction (X) and the vehicle width direction (Y), wherein the deformable fluid spring element is subjected to shear forces by the movement of the first and second spring parts relative to each other, and wherein the deformable spring element resists the shear forces.
- 11. A method for cushioning a first and a second spring part which are movable relative to each other and belong to a horizontal spring device of a vehicle seat having a seat part and a backrest part, in which the first and second spring parts are cushioned relative to each other by means of a deformable fluid spring element subjected to shear forces by movement of the vehicle seat relative to a vehicle body in at least one of the vehicle length direction (X) and the vehicle width direction (Y), wherein the deformable fluid spring element resists the shear forces, and wherein an internal pressure within the deformable fluid spring element is actively varied from the exterior according to at least one of an intensity of an introduced oscillation and a measured spring path in order to adapt the spring characteristic to the current introduced oscillation.

15. A vehicle seat, comprising:
a seat part extending in a vehicle length direction (X) and in a vehicle width direction (Y); and a seat substructure, including; at least one horizontal spring device, including; a first spring part, wherein the first spring part is connected to the seat part; a second spring part, wherein the second spring part is connect to a vehicle body; and a deformable spring element, wherein a first connecting region of the deformable spring element is connected to the first spring part, wherein a second connecting region of the deformable spring element is connected to the second spring part, wherein the deformable fluid spring element is arranged between the first and second spring parts so as to be deformed solely by the first and second spring parts, wherein movement of the seat part relative to the vehicle body in at least one of the vehicle length direction (X) and the vehicle width direction (Y) subjects the deformable spring element to a shear force, and
wherein the deformable spring element resists the shear force.- View Dependent Claims (16, 17, 18, 19, 20)
