A method for manufacturing the cushioning elements (200) may include utilizing a die (310) with a plurality of die elements (312) positioned in a particular arrangement. A polymer material, which may be a polymer foam material, is located between the die (310) and an extractor (320). The polymer material is compressed between the die (310) and the extractor (320), and the die elements (312) cut the polymer material to form a plurality of pad components (230), which are arranged like the die elements (312). The die (310) and the extractor (320) are separated, and the pad components (230) are secured to the extractor (320) in the arrangement of the die elements (312). Additionally, the pad components (230) are bonded to at least one material layer (210, 220) such that the pad components remain in the arrangement of the die elements.

A bicycle helmet comprises a helmet body including a shock absorbing insert and an external shell overlying at least partially the shock absorbing insert. The shock absorbing insert and the external shell have a plurality of structural bridges interconnected with each other with ventilation openings extending therebetween, a majority of the structural bridges having elongated ridges protruding from a base section. The elongated ridges and the base sections of the external shell overlie a respective one of the elongated ridges and the base sections of the shock absorbing insert.

An improved lightweight, shock-resistant and tension-proof safety helmet manufactured at a low cost is provided. The safety helmet includes a shell, which is manufactured by molding a liner using a thermoplastic resin, covering the outside of the liner with a reinforced fiber sheet, preparing a mold, disposing the liner upside down on a concave molding side of the mold, injecting a thermosetting resin between the liner and the molding side, hardening the thermosetting resin, and detaching the hardened thermosetting resin from the mold; and a cushion pad attached to the inside of the liner. The safety helmet may include a guide surface referred to as a wind flap in order to guide external air into the safety helmet.
摘要:
A molded headgear (50) formed from a laminated combination of a first, outer layer (60), a second, central layer (70) and a third, inner layer (80) of material relative to a wearer, said laminated combination being molded into a first shape (90) adapted to conform to a human head. The molded headgear (50) is flexible, pliable, bendable and resilient and springs back to its original shape once folded and released.
摘要:
In a process for producing a moulded part, a plate made of thermoplastic material that contains at least one reinforcement layer made of woven, nonwoven, knitted or braided fabrics, inserts or the like embedded in the plastic matrix is heated up to a temperature in the range of the melting point of the thermoplastic material, then shaped by means of a matrix and a male mould. In order to achieve a high, uniform surface quality that requires no subsequent processing with a rational production process, at least one easily deformable membrane that yields to pressure is arranged on at least one side of the plastic plate at least during the shaping process.
摘要:
A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).
摘要:
A method of making a foamed article comprises (a) milling a block or sheet of thermoplastic polymer to form a precursor; (b) crosslinking the thermoplastic polymer; (c) heating the precursor to a first temperature to soften the thermoplastic polymer; (d) infusing the thermoplastic polymer with at least one inert gas at a first pressure that is sufficient to cause the at least one inert gas to permeate into the softened thermoplastic polymer; and (e) while the thermoplastic polymer is softened, reducing the pressure to a second pressure below the first pressure to at least partially foam the precursor into a foamed article, wherein the foamed article is substantially the same shape as the precursor.
摘要:
A method of applying a polymeric film to an article when forming an assembly according to the invention comprises: providing a polymeric film (100,200,300,400,500,600,700,800) sized to cover at least a portion of at least one exterior surface of the article (104,204,304,704,804); providing at least one gaseous agent (206) to form a coating (208,308,408,508,718) on at least one surface of the polymeric film and/or at least one exterior surface of the article to be contacted when forming an assembly; contacting at least a portion of the polymeric film and at least a portion of the at least one exterior surface of the article; and form-fitting the polymeric film with the portion of the at least one exterior surface of the article.
摘要:
Die Erfindung betrifft eine Polsterlagenanordnung (01) sowie ein Verfahren zu deren Herstellung. Hierbei weist die Polsterlagenanordnung (01) eine Mehrzahl von mit elastischen Formkörpern gefüllte Hohlkörper (05) auf, die zwischen einer thermoplastisch verformbaren Basislage (03) und einer thermoplastisch verformbaren Decklage (02) in einem Lagenverbund ausgebildet sind. Zur Erzielung eines besonders kostengünstigen Aufbaus wird zur Bildung eines Hohlkörpers (05) sowohl die Basislage (03) als taschenförmigen Ausstülpung (07) als auch gleichgerichtet die aufliegende Decklage (02) mit einem in die Ausstülpung (07) hineinreichenden Vorsprung (08) umgeformt.
