A pneumatic element including: a first, a second, and a third air chamber which are coupled to one another, the first air chamber being coupled to the second air chamber by a weld joint and the second air chamber being coupled to the third air chamber by another weld joint; and an overflow area, which is arranged within the weld joints along a longitudinal axis of the pneumatic element, for a pneumatic communication between the air chambers. Each of the air chambers has a first state in which a pressure inside the air chambers corresponds to a pressure outside of the air chambers and a second state in which the pressure inside the air chambers is greater than the pressure outside of the air chambers. Furthermore, a flow opening is provided for a pneumatic communication between the overflow region and the second air chamber in the first state. |

1. A pneumatic element, comprising:
a first, a second and a third air chamber, which are coupled to one another, wherein the first air chamber is coupled to the second air chamber by means of a weld joint, and the second air chamber is coupled to the third air chamber by a further weld joint, an overflow area, which is arranged within the weld joints along a longitudinal axis of the pneumatic element, for pneumatic communication between the air chambers, wherein the air chambers each have a first state in which a pressure in the interior of the air chambers corresponds to a pressure outside the air chambers, and have a second state in which the pressure in the interior of the air chambers is greater than the pressure outside the air chambers, a flow opening for pneumatic communication between the overflow area and the second air chamber in the first state. |
