An actuating portion for a vehicle door handle assembly, in particular an inner door handle assembly, wherein the actuating portion includes a carrier portion formed by co-injection, having a core and an outer layer, and a decorative portion connected to the carrier portion, in particular integrally, wherein the actuating portion has been produced in a multi-component injection-molding method, in particular in a three-component injection-molding process.

A section of (cured and non-liquid) textured foam includes at least a portion of a foam-upper-surface that substantially resembles a look of a human fingerprint for a purpose of providing enhanced grip traction between the at least the portion of the foam-upper-surface of the textured foam and a hand or a foot of a user of the textured foam. Disposed opposite of the foam-upper-surface of the textured foam may be an adhesive backing for attachment to a diverse variety of exterior surfaces where improved grip traction is desired. Systems and methods for making such textured foam that substantially resembles a look of a human fingerprint may utilize a heating means and a compression means. Such textured foam that resembles the look of a human fingerprint may be located on an upper surface of a vehicle and/or on an exterior surface of a handle to minimize against slippage.

The invention discloses a method of manufacturing a handrail assembly including steps of 1) providing a first material layer and a second material layer, wherein the second material layer is a hot melt material; 2) stacking the second material layer on the first material layer to form a substrate layer with an integrated structure; 3) curling the substrate layer to form a handrail cover matching a handrail tube, wherein the handrail cover is a sleeve structure and the second material layer is located at an inner side of the handrail cover; 4) inserting the handrail tube matching the handrail cover into the handrail cover to form a handrail assembly semi-finished product; 5) baking the handrail assembly semi-finished product until the second material layer is completely melted; and 6) cooling the handrail assembly semi-finished product after baking to form the handrail assembly.

A handrail assembly, a manufacturing method for the handrail assembly, a support frame structure having the handrail assembly, and a child carrier. The handrail assembly comprises a handrail body, wherein the handrail body is covered with a first protective layer of a flexible structure, the first protective layer is covered with a second protective layer, the second protective layer shields the first protective layer to prevent the first protective layer from being exposed to the outside. The support frame structure comprises a front support assembly, a rear support assembly, a push rod assembly, a connecting assembly and a handrail assembly, a connecting portion of the handrail assembly being detachably connected to the connecting assembly. The handrail assembly can prevent the first protective layer from being exposed to the outside, and prevent children from accidentally swallowing the filling of the first protective layer, thereby guaranteeing the life safety of children.

A fiber-reinforced polymer composition that contains a polymer matrix and a plurality of long reinforcing fibers that are distributed within the polymer matrix is provided. The polymer matrix contains a propylene polymer and constitutes from about 30 wt. % to about 90 wt. % of the composition. The fibers constitute from about 10 wt. % to about 70 wt. % of the composition. Further, the polymer composition exhibits a spiral flow length of about 450 millimeters or more as determined in accordance with ASTM D3123-09 and a volatile organic content of about 100 micrograms per gram or less as determined by VDA 277.

A method and apparatus for extrusion of an article is provided. A die assembly can apply flows of thermoplastic material to an array of reinforcing cables to form a composite extrusion. A slider fabric can be bonded to one side of the composite extrusion. After exiting the die assembly, the slider fabric can act to support the extrudate as it passes along an elongate mandrel, which can cause the base of the slider fabric to change shape from a flat profile to the final internal profile of the article. The extruded article can then be cooled to solidify the material. The die can include cooling for the slider fabric and means for promoting penetration of the thermoplastic into reinforcing cables.

One general aspect includes a method of manufacturing a handle, the method including: providing a core element; providing a mold; strategically positioning the core element within the mold such that a formable material can be injected into the mold (when in a molten state) to operatively encapsulate the core element and such that the core element remains stationary while being operatively encapsulated by the formable material; and injecting the formable material (when in the molten state) into the mold to operatively encapsulate the core element and be formed, by the mold, into a handle configured to be joined to a window support pillar of a vehicle interior.

In some embodiments, a method of forming a bonded assembly includes: providing a first object comprising a first surface having a plurality of locking orifices formed therein, each of the plurality of locking orifices including an opening on the surface of the object and a cavity extending in the first object; positioning an adhesive on at least one of the first surface of the first object and a second surface on a second object; positioning the first surface of the first object on the second surface of the second object with the adhesive between the first and second surfaces; and curing the adhesive to form the bonded assembly.

A resin composition useful for making an inside door handle with a skin-core structure made by using co-injection, an inside door handle manufactured using the resin composition, and a method for manufacturing such a door handle are provided herein.
