An insert element (8) for sealing cavities (6, 7) in vehicle body carriers (4) has sealing means constituted by a foamable material (11) which is secured in the cavities (6, 7) by securing means (9). The insert element (8) comprises a foamable material (11) and a support structure (10) which comprises a frame (13) and an inner part (14) for carrying the foamable material (11). The frame (13) has at least two lateral and not immediately oppositely arranged support faces (12), and carries securing means (9). With this arrangement, the foamable material can completely engulf the securing means (9) with foam during the foaming process and can flow into apertures of an intermediate metal sheet (5) foreseen for receiving the securing means (9). This ensures that these apertures are impermeably sealed against air and noise during the foaming process. The foamable material is preferably constituted of a thermoplastic polymer which can form a closed-celled foam, thus increasing the noise insulating and noise absorbing properties, whilst also acting as a moisture barrier and an airtight sealant.

Insert element for sealing of hollow cavities in vehicle body carriers by means of a foaming process, in particular vehicle body pillars, having sealing means comprising a foamable material and means for securing the insert element in the hollow cavities, whereby the insert element comprises a support structure for the foamable material, said support structure having a frame and an inner part, wherein the frame has at least two lateral and not immediately oppositely arranged support faces characterized in that at least one of the support faces is formed as securing means and is a clip, said securing means being arranged such, that the foamable material completely engulfs the clip during the foaming process and thereby flows into an aperture for receiving the securing means in order to ensure that this aperture is impermeably sealed against air and noise.
Insert element for sealing cavities in vehicle body carriers, in particular in vehicle body pillars, having means for sealing constituted of foamable material and having means for securing the insert element in the cavities, wherein the insert element is comprised of a single piece of foamable material and wherein the securing means comprises a frame having at least two lateral, not immediately oppositely arranged support faces.
