Definitions

  • the invention relates to an upper reveal for a window opening of a motor vehicle door frame. More particularly, the invention relates to a method of manufacturing an upper reveal ttiat conforms to the curvature of a window opening of a motor vehicle door frame.
  • A. door of a motor vehicle typically includes a door frame defining a window opening.
  • a retractable window pane and a fixed window pane are disposed within the window opening.
  • An upper reveal is typically secured to a header portion of the door frame and extends along the window opening. The upper reveal provides sealing engagement between the header and a body portion of the motor vehicle when the door is closed. At the same time, an outside surface of the upper reveal is disposed along the exterior of the door of the motor vehicle. Therefore, the upper reveal must have an aesthetically pleasing appearance.
  • the window opening of the door frame has a curved portion or corner to complement the overall styling of the motor vehicle.
  • the upper reveal must be able to be bent "to conform to such curved portions or corners.
  • Upper reveals generally include an outer layer, which is typically a thermoset material such as PVC or EPDM rubber, extruded onto a rolled metal carrier. The upper reveal is then stretch bent in order to conform to the curved or corner portion of the window opening. Bending the upper reveal tends, however, to adversely affect the upper reveal. More specifically, bending often results in appearance flaws such as crimping, creasing, bulging, buckling, or the like.
  • Upper reveals made up of two discrete pieces for conforming to the curvature of the window opening have been utilized to avoid the aforementioned appearance flaws. These upper reveals include a generally planar, extruded portion and a stamped metal portion having molded edges. The extruded portion fits along a generally planar portion of the window opening while the stamped metal portion conforms to the curvature of the corner or curved portion of the window opening. This configuration results, however, in an unattractive, visible joint at the spot where the mismatched extruded and stamped portions meet, thereby detracting from the overall appearance of the motor vehicle. In addition, the need for expensive tooling required to manufacture the stamped metal portion of the upper reveal is not cost-effective.
  • a method for manufacturing an upper reveal that conforms to a curved portion of a window opening of a motor vehicle door frame.
  • the upper reveal is formed from TPV and a carrier.
  • the method includes the steps of: co-extruding the TPV with the carrier; curing the TPV to form the upper reveal; heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV; and bending the upper reveal to conform to the curved portion of the window opening of the motor vehicle door frame.
  • a method for manufacturing an upper reveal, having a decorative trim, for a window opening of a motor vehicle door frame from a TPV material and a carrier includes the steps of: co-extruding the TPV with the carrier; curing the TPV to form the upper reveal; heating the upper reveal to a temperature greater than a heat deformation temperature of the TPV; bending the upper reveal to conform to the curved portion of the window opening of the motor vehicle door frame; and applying the decorative trim to the upper reveal.
  • a method for manufacturing an upper reveal, having opposing ends covered by end caps, for a window opening of a motor vehicle door frame from TPV and a carrier includes the steps of: co-extruding the TPV with the carrier; curing the TPV to form the upper reveal; and molding the end caps to the opposing ends of the upper reveal.
  • a method for manufacturing an upper reveal from TPV of different durometer values for conforming to a curved portion of a window opening of a motor vehicle door frame includes the steps of: co-extruding the TPV of different durometer values, curing the TPV to form the upper reveal, heating the upper reveal to a temperature greater than a heat deformations temperature of the TPV; and bending the upper reveal to conform to the curved portion of the window opening of the doo ⁇ frame.

  • the bending press 92 is utilized for bending the upper reveal 32 to conform to the curved portion 30 of the window opening 22.
  • the decorative trim 80 mary be applied to the upper reveal 32 either as the TPV is being cured or after the upper reveal 32 has been bent to conform to the curved portion 30 of the window opening 22.
  • the upper reveal 32 is secured to the header flange 34 extending along the header 35 of the door frame 14.
  • the upper reveal 32 in yet another method of manufacturing the upper reveal 32 according to the invention, as shown in Figure 12, TPV of different durometer values is fed into the extrusion die 82 to form the molded strip 36.
  • the carrier 38 is not utilized in the current method.
  • the upper reveal 32 includes the molded strip 36 of TPV of different durometer values.
  • the upper reveal 32 is then passed through a series of cooling baths 84 in order to cure the TPV.
  • the series of cooling baths 84 include at least one sizing guide member 86 for maintaining the cross-section of the upper reveal 32 as the TPV is cured.
  • the upper reveal 32 is then cut to a predetermined length by a cutter 88.
  • the upper reveal 32 is heated in the oven 90 to a temperature that is above the heat deformation temperature of the TPV.
  • the heat deformation temperature for XPV is a temperature between approximately 120 0 C and 150 0 C.
  • a bending press 92 is utilized for bending the upper reveal 32 to conform to the curved portion 30 of the window opening 22.
  • the decorative trim 80 may be applied to the upper reveal 32 either as trie TPV is being cured or after the upper reveal 32 has been bent to conform to the curved portion 30 of the window opening 22.
  • the upper reveal 32 is secured to the header flange 34 extending along the header 35 of the door frame 14.
