Wrapped part assembly with edge/corner defining inserts

Abstract

An insert is assembled to a base interior part at either an edge or a corner of the part that is later wrapped with a cut and sewn jacket cover. The assembly comprises a substrate, an insert and a cover. The substrate has a base edge and the insert has a contour defining edge attached to the substrate with the contour defining edge aligned with the base edge. The cover is wrapped over the insert and the substrate to provide a wrapped edge that covers over the contour defining edge. A method of manufacturing a covered interior part of a vehicle comprises securing an insert having a contour defining edge to the interior panel and wrapping the insert and the interior panel with a cover.

DETAILED DESCRIPTION

(11) The illustrated embodiments are disclosed with reference to the drawings. However, it is to be understood that the disclosed embodiments are intended to be merely examples that may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. The specific structural and functional details disclosed are not to be interpreted as limiting, but as a representative basis for teaching one skilled in the art how to practice the disclosed concepts.

(12) Referring to FIG. 1, a wrapped interior part assembly 10, or assembly, is illustrated that includes a substrate part 12 on which an overlaid insert 14 is assembled prior to covering the assembly with a cover 16. The substrate part 12 may be an interior part for a car, such as a dashboard, interior door panel, console, glove box door, seat, or the like.

(13) The insert 14 is assembled to the substrate part 12 near a base edge 18 of the substrate part 12. The insert 14 includes a contour defining edge 20 that is positioned in alignment with the base edge 18. The contour defining edge 20 is outboard of the base edge 18 and provides a sharp feature line when the cover 16 is wrapped over the assembly and insert and substrate 12.

(14) While not necessary in every assembly 10, a spacer 24 may be assembled between the substrate part 12 and overlaid insert 14 to provide a cushioned feel that emphasizes the suppleness of a leather cover 16. The spacer 24 may be a foam layer or sheet. The spacer 24, as shown in FIG. 1, extends across the substrate part 12 and partially over the overlaid insert 14, but does not extend across the contour defining edge 20. In several of the embodiments to be described below, the spacer 24 extends over the contour defining edge 20.

(15) The substrate part 12 includes a facing wall 26, or outer surface, of the substrate part 12. In many applications, the substrate part may be a vinyl part that includes the Class A surface of the part. Higher level trim is provided by wrapping the substrate part 12 with a premium covering material, such as leather. While leather is the most common premium covering material, the cover may also be made of other premium fabrics or materials. In many instances, the substrate part 12 is milled or machined to provide clearance for the wrapped cover 16 in areas where the assembly 10 may interfere with assembled parts or adjacent vehicle components. The substrate part 12 may also include a side wall 28 that extends inwardly from the facing wall 26. The side wall 28 may also require machining to provide clearance for the addition of the cover 16 to the assembly 10.

(16) A recess defining wall 30 may be provided that extends inwardly relative to the facing wall 26. The recess defining wall 30 defines a recess, or opening, in the substrate part 12 that may be used to insert an attachment 32, such as an air vent, trim piece, or the like. Alternatively, the wall 30 may be adapted to receive a different part or may be aligned with another plug-in part. The attachment 32 may be a snap-in part, adhesively secured part, or otherwise fastened to the substrate part 12 after the cover 16 is attached to the assembly 10. The overlaid insert 14 has an inner surface 34 that is placed in a face-to-face relationship on the facing wall 26 of the substrate part 12. The overlaid insert 14 also includes an outer surface 36 that faces away from the inner surface 34. The outer surface 36 is preferably tapered toward the substrate part 12 facing wall 26 to reduce the possibility that the insert may be discernable or detectable after the cover 16 is attached.

(17) Referring to FIG. 2, the assembly 10 is shown as an exploded perspective view of a small segment of the assembly 10. The assembly 10 includes the substrate part 12 that includes the base edge 18. The substrate 12 includes a facing wall 26 and a side wall 28 that are covered by the cover 16 when it is wrapped over the assembly 10. The insert 14 provides the contour defining edge 20 when it is assembled onto the substrate 12 with the contour defining edge 20 generally following the base edge 18. The inner surface 34 of the insert 14 is attached to the facing wall 26 of the substrate 12. The outer surface 36 of the insert 14 faces in generally the same direction as the facing wall 26 of the substrate 12. The outer surface 36 tapers toward the facing wall 26 of the substrate part 12. The spacer 24 is shown disposed between the outer surface 36 of the insert 14 and the cover 16.

(18) FIGS. 3-8 illustrate several different embodiments of the assembly 10 that include several different types of inserts. Referring to FIG. 3, an insert 14 that is like the insert shown in FIGS. 1 and 2 is shown assembled to a substrate 12. The substrate 12 defines a base edge 18 while the insert 14 includes the contour defining edge 20. The spacer 24 may extend across the outer surface 36 of the insert 14 and over the contour defining edge 20 to also cover the side wall 28 of the assembly 10. A snap-in fastener 38 may be provided as an integrally molded part of the insert 14 to secure the insert 14 to the substrate 12. Alternatively, the snap-in fastener may be a screw or separate snap-in fastener 38 as shown below and described with reference to FIG. 4.

(19) Referring to FIG. 4, the insert 14 is shown to be assembled into an outer surface recess 40 that is formed in the facing wall 26 of the substrate part 12. A screw 42 is shown that is used to secure the insert 14 to the substrate part 12. A spacer 24 is assembled over the insert 14 and the facing wall 26 of the substrate 12. The recess 40 locates the insert on the substrate 12. The recess 40 may be formed by machining or milling the surface of the substrate 12 to remove material from the substrate 12. Alternatively, the substrate part 12 may be molded to define the recess 40. The substrate 12 may be bored to form a hole or opening to receive the screw 42 or the snap-in fastener 38 (shown in FIG. 3).

(20) A cylindrical area 46 may be provided at the contour defining edge 20 to provide a more durable contour defining edge 20 that provides a small radius contour defining edge 20 instead of a sharp point, as shown in FIGS. 1-3.

(21) Referring to FIG. 5, a corner insert 48 is shown to be installed in a recess 50. The corner insert 48 may be secured to the substrate 12 by an adhesive 52. An inverted V-shaped protrusion 56 is provided on the corner insert 48 at a location that is recessed laterally relative to the side wall 28. The inverted V-shaped protrusion 56 is provided on a top surface 58 of the corner insert 48. A spacer 24 is assembled over the top surface 58 and the substrate 12 before it is covered by the cover 16.

(22) Referring to FIG. 6, another embodiment of a corner insert 48 is shown that is secured by an adhesive 52 to the substrate 12. The corner insert 48 includes an inverted V-shaped protrusion 56 that is located at a corner 60 of the corner insert 48. The V-shaped protrusion 56 extends diagonally relative to the facing wall 26 and side wall 28 of the corner insert 48. The spacer 24 is assembled over the corner insert 48 and the substrate 12, but does not extend over the V-shaped protrusion 56. The cover 16 is assembled over the insert 48, substrate 12 and spacer 24.

(23) Referring to FIG. 7, another corner insert 48 is illustrated that is assembled over the base edge 18 of the substrate 12. The inverted V-shaped protrusion 56 extends from a side portion 62 of the insert 48. The insert 48 is assembled into a recess 50 that is formed either by machining or molding in the substrate 12 as previously described. The spacer fabric 24 is shown to be assembled over the facing wall 26 and side wall 28. The spacer 24 also extends over the protrusion 56 and the insert 48.

(24) Referring to FIG. 8, this view is taken as a cross-sectional view in FIG. 1 to show the application of the corner insert 48 in a recess defining wall 30 that is adapted to receive an attachment 32, such as an air vent or trim piece. The corner insert 48 is assembled to the substrate 12 to provide a sharp corner in the area where the attachment 32 is adjacent to the substrate 12. The insert 48, shown in FIG. 8, does not include a protrusion, but is L-shaped and extends along the edge of the substrate with the base edge 18 and substrate 12 being inboard of the contour defining edge 20. The cover 16 and the foam spacer 24 extend across the facing wall 26, the corner insert 48 and the recess defining wall 30.

(25) Referring to FIG. 9, a ball-shaped rounded corner 64 is illustrated that may be provided on the insert 14 shown in FIGS. 1-4 or on a corner insert 48 as shown in FIGS. 5-8. The ball-shaped rounded corner 64 provides a slightly rounded end of small radius. The ball-shaped rounded corner 64 reduces the sharpness of the finished corner and reduces any tendency to pierce the cover 16.

(26) Referring to FIG. 10, another alternative embodiment of a corner insert 48 is shown that includes a ball-shaped rounded corner 64 that is provided where three faces intersect on the insert. Cylindrical edges 46 are provided on the edges that lead to the ball-shaped rounded corner 64. The cylindrical edges 46 provide a rounded linear edge between two faces of the insert 48. The rounded corner 64 or cylindrical edge 46 provide a smaller radius surface over which the cover 16 is wrapped, as described with reference to FIGS. 1-8 above.

(27) While the embodiment of FIGS. 1-4 is shown with the triangular protrusion 22 extending upwardly relative to the substrate part 12, it should be understood that the triangular protrusion 22 may be oriented in a diagonal direction similar to the protrusion 56 shown in FIG. 6 or may extend over the side wall 28 of the substrate 12 similar to the corner insert 48 shown in FIG. 7.

(28) The structural elements shown and described with reference to the drawings may be modified or combined with other structural features shown in the other figures of the drawings. The embodiments described above are specific examples that do not describe all possible forms of the disclosure. The features of the illustrated embodiments may be combined to form further embodiments of the disclosed concepts. The words used in the specification are words of description rather than limitation. The scope of the following claims is broader than the specifically disclosed embodiments and also includes modifications of the illustrated embodiments.
