Fastening strap assembly and foam article including same
One aspect of the present invention provides a fastening strap assembly for used in a foam article. The fastening strap assembly includes a substrate having two sidewalls each formed along one side thereof in a longitudinal direction and spaced apart from each other; a substantially fishbone-shaped fastening member disposed between the sidewalls and adhered to the substrate, the fastening member having an elongate central rib and a plurality of fastening parts laterally extending from either sides of the rib and longitudinally spaced apart from each other, each fastening part having a plurality of hooks formed on a upper surface thereof; and a magnetic layer disposed between the substrate and the fastening member. The fastening strap assembly of the present invention has a unique sideway bending/curving function. Another aspect of the present invention provides a foam article, such as a seat cushion, including the sideway-bendable fastening strap assembly.
1. A fastening strap assembly for foam article comprising:
a substantially fishbone-shaped fastening member having an elongate central rib and a plurality of fastening parts laterally extending from either sides of the rib and longitudinally spaced apart from each other, each fastening part having a plurality of hooks formed on a upper surface thereof;
a laterally stretchable/compressible substrate having a fishbone shape substantially the same as that of the fastening member and being disposed under the fastening member and bonded thereto; and
a protective layer having a fishbone shape substantially the same as that of the fastening member and disposed above the fastening member to cover the fastening member, and a magnetic material layer coated on an outer surface thereof,
wherein the substrate, the fastening member and the protective layer are bonded together along a periphery of the fastening parts of the fastening member and perforations are provided in the protective layer and magnetic material layer along the bonded periphery thereof.
