  • Patent number: 11655635
    Abstract: Disclosed herein are plaster boards that include first and second layers of hardened plaster material, a liner attached to the first layer of hardened plaster material, and a first material (e.g., a polymer material such as a viscoelastic polymer) adhered between the liner and the second layer of hardened plaster material. The liner includes one or more structurally weakened regions each extending substantially from a first edge to a second opposing edge of the plaster board. The structurally weakened regions of the liner may facilitate creation of a fissure that propagates substantially within a plane within the plaster board. Methods for making the plaster boards may involve drying wet plaster material while it is in contact with a liner having structurally weakened regions, processing a liner to form its structurally weakened regions while in contact with wet plaster material, or processing a liner to form its structurally weakened regions while in contact with hardened plaster material.

  • Patent number: 8042830
    Abstract: A device is provided for snap-fastening an airbag unit in a subassembly of a motor vehicle, especially in a steering wheel of a motor vehicle, snap-in elements that are associated with each other being provided on the airbag unit and on the subassembly of the motor vehicle. In order to be able to snap-secure an airbag unit both to a plate-shaped subassembly and to a subassembly having a lateral wall, at least one snap-in hook is provided on the airbag unit or on the subassembly of the motor vehicle, at least one pivotable plastic snap-in clip being associated therewith on the other subassembly. The snap-in hook engages with said clip in at least one section thereof when in the snap-in position.
