Abstract
A vehicle seat cushion is formed by depositing filaments of a thermoplastic to form a mesh member while embedding straight strands of thermoplastic into the mesh member. The straight strands modify a property of the mesh member, such as crush resistance. The strands may have barbs to improve mechanical bonding. The filaments may be deposited directly onto a conveyor or, alternatively, may be deposited into molds which travel along the conveyor.
Claims20
An apparatus comprising:
- a plurality of strands of a first thermoplastic material, extending from a first surface of the apparatus to a second surface of the apparatus opposite the first surface;
- and
- a mesh member comprising a set of filaments of a second thermoplastic material, wherein each member of the set of filaments is looped and bonded to at least one other member of the set of filaments, the mesh member surrounding the plurality of strands.
A method comprising:
- extruding a first thermoplastic material through a plurality of openings in a die plate to form a set of filaments;
- depositing the filaments onto a conveyor to form a mesh member, wherein each member of the set of filaments is looped and bonded to at least one other member of the set of filaments;
- and
- while depositing the filaments onto the conveyor, embedding a plurality of strands of a second thermoplastic material in the mesh member.
