Structural unit in the form of a cavity-formed part, and use thereof

摘要

The unit has formed parts including two support layers and a thermoplastic support (7a), where the formed parts fashion at a cavity. One formed part has a multilayered structure (5a) with a flat material (6a) associated to the former support layer. The flat material is laminated to the former support layer on the side of the former support layer facing away from the cavity, where the flat material is extensible or flexible. The cavity is partially or completely filled with one fluid or solid filling such as gels and foams. An independent claim is also included for a process for production of a structural unit.
