Abstract
A partition for sealing and/or supporting a cavity includes a carrier and an expansion material on the carrier. The expansion material transitions from an initial state to an expanded state by activation. The carrier includes at least one compensation element that provides variability of an effective sealing surface of the carrier in case of a force acting on the carrier. The carrier also includes a limiting element that limits movement of at least one portion of the carrier that accompanies a change in the effective sealing surface of the carrier.
Claims18
A partition for sealing and/or supporting a cavity, the partition comprising:
- a carrier comprising a stationary portion and a movable portion that is configured to move relative to the stationary portion;
- and
- an expansion material on the carrier, wherein the expansion material is configured to expand from an initial state to an expanded state by activation,
- wherein the carrier comprises at least one compensation element, between the stationary portion and the movable portion, the at least one compensation element configured to bend to provide variability of an effective sealing surface of the carrier when a force due to the expansion of the expansion material is acting on the carrier, and
- wherein the carrier further comprises a limiting element on the carrier and that is configured to limit bending of the at least one compensation element to limit the change in the effective sealing surface of the carrier.
