Two-shot polymeric component with attachment feature and method of producing same
View Patent ↗The present invention provides a two-shot injection molded polymeric component having first and second shots made from polymeric materials. The first shot is made from a relatively hard polymeric material, while the second shot is made from a polymeric material which may differ from the first shot by way of color or polymer type. In this way, the second shot provides texture and aesthetic value to the component. Integrally molded with the second shot is an attachment feature that allows an accessory to be attached proximate the back side of the component without the use of a separate fastener or other separate attachment feature.
1. A two-shot injection molded polymeric component, comprising:
a first injection molded portion made from a polymeric material and including first and second opposing sides; and
a second injection molded portion made from a polymeric material, and formed such that at least some of the second portion is disposed adjacent the first side of the first portion and at least some of the second portion is disposed adjacent the second side of the first portion, the second portion including an attachment feature integrally molded therewith, the attachment feature being configured to facilitate attachment of an object to be attached proximate one side of the first portion.
2. The polymeric component of claim 1 , wherein the first portion includes an aperture disposed therethrough for facilitating communication between the first side and the second side, and wherein the second portion traverses the aperture, thereby allowing at least some of the second portion to be disposed adjacent the first side and at least some of the second portion to be disposed adjacent the second side.
3. The polymeric component of claim 1 , wherein the first portion includes an edge adjacent the first and second sides, and wherein the second portion traverses the edge, thereby allowing at least some of the second portion to be disposed adjacent the first side and at least some of the second portion to be disposed adjacent the second side.
4. The polymeric component of claim 1 , wherein the attachment feature is further configured to retain the second portion proximate the first portion, thereby eliminating the need for a chemical bond between the first and second portions.
5. The polymeric component of claim 1 , wherein the attachment feature includes an elongate member and a connection member, the elongate member being configured to wrap around a portion of the object to be attached and to cooperate with the connection member to retain the object to be attached proximate one side of the first portion.
6. The polymeric component of claim 1 , wherein the attachment feature includes a clamp portion having a pair of arms, the arms being elastically flexible to facilitate receiving and retaining the object to be attached.
7. The polymeric component of claim 1 , wherein the first portion is made from a polymeric material that includes a polypropylene, and the second portion is made from a polymeric material that includes a thermoplastic elastomer.
8. A two-shot injection molded automotive interior trim component, comprising:
a structural portion made from a polymeric material and including a show side and a back side opposite the show side; and
a skin made from a polymeric material, a portion of the skin being formed adjacent the show side and a portion of the skin being formed adjacent the back side, the skin including an attachment feature integrally molded therewith, the attachment feature being disposed proximate the back side and configured to facilitate attachment of an automotive accessory proximate the back side.
9. The trim component of claim 8 , wherein the structural portion includes an aperture disposed therethrough for facilitating communication between the show side and the back side, and wherein the skin traverses the aperture, thereby allowing a portion of the skin to be disposed adjacent the show side and a portion of the skin to be disposed adjacent the back side.
10. The trim component of claim 8 , wherein the structural portion includes an edge adjacent the show side and the back side, and wherein the skin traverses the edge, thereby allowing a portion of the skin to be disposed adjacent the show side and a portion of the skin to be disposed adjacent the back side.
11. The trim component of claim 8 , wherein the attachment feature is further configured to retain the skin proximate the structural portion, thereby eliminating the need for a chemical bond between the skin and the structural portion.
12. The trim component of claim 8 , wherein the attachment feature includes an elongate member and a connection member, the elongate member being configured to wrap around a portion of the automotive accessory and to cooperate with the connection member to retain the automotive accessory proximate the back side of the structural portion.
13. The trim component of claim 8 , wherein the attachment feature includes a clamp portion having a pair of arms, the arms being elastically flexible to facilitate receiving and retaining the automotive accessory.
14. The trim component of claim 8 , wherein the attachment feature is configured to facilitate attachment of at least one of a wiring harness, an audio speaker, a noise absorption pad, and a bolster proximate the back side.
15. The trim component of claim 8 , wherein the attachment feature includes a clip configured to cooperate with an aperture in the automotive accessory for retaining the automotive accessory proximate the back side.
