Abstract: The invention relates to a partition (1) for sealing and/or supporting a cavity, comprising a carrier (2) and an expansion material (3) arranged on the carrier (2), which expansion material can be transferred from an initial state to an expanded state by means of activation, wherein the carrier (2) comprises at least one compensation element (4), which provides variability of the effective sealing surface (5) of the carrier (2), such that a change in the effective sealing surface (5) of the carrier (2) can be brought about by means of a force acting on the carrier (2), a limiting element (6) being provided, by means of which a movement of at least one portion of the carrier (2) which accompanies the change in the effective sealing surface (5) is limited.

Abstract: A lengthwise extended component contains of a support that possesses flow channels in the direction of its longitudinal axis. The support additionally possesses external surfaces that are offset to each other in the direction of the longitudinal axis as well as a lateral external surface. These external surfaces are provided with a layer of a thermally expansible and curable composition. Reinforcing components of this type are suitable for stiffening and/or reinforcing hollow supports, such as the A-, B- or C-pillars, the roof edges or the rocker panels of vehicles, especially passenger cars.

Abstract: A molding is described, the outer edge region of which comprises a thermally expandable material that has a high coefficient of friction in relation to metal or plastic. In its inner region this molding has an aperture and/or recess for receiving a mounting aid. The molding is suitable as a sealing and acoustically active bulkhead part and with the aid of friction forces can be fixed mechanically in the cavity of structural components without these components having to exhibit bores, apertures or other devices for fixing the bulkhead part.
