PNEUMATIC DEVICE
First Claim
1. A pneumatic device for varying a contour of a seat bearing surface of a vehicle seat, comprising:
- a carrier foil composed of a first and a second foil ply which are arranged adjacent to one another;
a first bladder for varying the contour of the seat bearing surface, comprising a bladder chamber which can be filled with a pressure medium;
a first pressure medium line which is connected to the first bladder and which is formed by connection of the first and second foil plies along a first line-side connection seam in order to create a pressure medium connection to the bladder chamber of the first bladder, wherein one foil ply of the first and second foil plies has, in the region of the first bladder, an opening in order to form a pressure medium channel to a further bladder, which can be filled with the pressure medium and which is connected to one of the foil plies.

Abstract
A pneumatic device for varying a contour of a seat bearing surface includes a carrier foil TF composed of a first and a second foil ply which are arranged adjacent to one another. The pneumatic device has a first bladder for varying the contour of the seat bearing surface, including a bladder chamber which can be filled with pressure medium (DM). The pneumatic device furthermore has a first pressure medium line connected to the first bladder and which is formed by connection of the first and second foil plies along a line-side connection seam to create a pressure medium connection to the bladder chamber of the first bladder. One foil ply has, in the region of the first bladder, an opening in order to form a pressure medium channel to a further bladder, which can be filled with pressure medium and is connected to one of the foil plies.
