Method for stitching vehicle interior components and components formed from the method
View Patent ↗A method of applying stitching to an interior component is provided herein. The method including the steps of: a) penetrating the outer skin layer, the substrate layer and the intermediary layer with a chain stitch pattern machine to form a piercing therethrough; b) retracting the chain stitch pattern machine from the outer skin layer, the substrate layer and the intermediary layer; c) inserting a needle through the piercing through the substrate layer, the intermediary layer and the outer skin layer to grasp a thread positioned on the outer skin layer; d) pulling the thread through the outer skin layer, the intermediary layer and the substrate layer; e) advancing the interior component to another position, wherein a backside of the substrate layer is free of obstructions; and f) repeating steps a-e until a predetermined amount of stitches are applied to the interior component.
1. A method of applying stitching to an interior component, comprising an outer skin layer, a substrate layer and an intermediary layer located between the outer skin layer and the substrate layer, the method comprising:
a) penetrating the outer skin layer, the substrate layer and the intermediary layer with an awl located on an upper arm of a chain stitch pattern machine to form a piercing therethrough;
b) retracting the awl of the upper arm of the chain stitch pattern machine from the outer skin layer, the substrate layer and the intermediary layer;
c) inserting a needle of a lower arm of the chain stitch pattern machine through the piercing through the substrate layer, the intermediary layer and the outer skin layer to grasp a thread positioned on the outer skin layer;
d) pulling the thread through the outer skin layer, the intermediary layer and the substrate layer;
e) advancing the interior component to another position, wherein a backside of the substrate layer is free of obstructions; and
f) repeating steps a-e until a predetermined amount of stitches are applied to the interior component.
2. The method as in claim 1 , wherein outer skin layer, is formed from one of the following; vinyl, leather and thermoplastic polyolefin; and the intermediary layer is a foam and the substrate layer is formed from plastic.
3. An interior component formed by the method of claim 2 , wherein the interior component is an interior trim piece of a vehicle.
4. The interior component of claim 3 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
5. An interior component formed by the method of claim 1 , wherein the interior component is an interior trim piece of a vehicle.
6. The interior component of claim 5 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
7. The method as in claim 1 , wherein outer skin layer, is formed from leather and the intermediary layer is foam and the substrate layer is formed from plastic.
8. The interior component formed by the method of claim 1 , wherein the backside of the substrate layer is free of obstructions along the entire stitch length.
9. The interior of claim 8 , wherein the interior component is an interior trim piece of a vehicle.
10. The interior component of claim 9 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
11. The interior component formed by the method of claim 1 , wherein the backside of the substrate layer is configured to have a separate component attached thereto, the separate component being free of any obstructions.
12. The interior component of claim 11 , wherein the interior component is an interior trim piece of a vehicle.
13. The interior component of claim 12 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
14. The interior component of claim 13 , wherein outer skin layer is formed from leather and the intermediary layer is foam and the substrate layer is formed from plastic.
15. A method of applying stitching to an interior component, comprising an outer skin layer, a substrate layer and an intermediary layer located between the outer skin layer and the substrate layer, the method comprising:
a) penetrating the outer skin layer, the substrate layer and the intermediary layer with a chain stitch pattern machine to form a piercing therethrough;
b) retracting the chain stitch pattern machine from the outer skin layer, the substrate layer and the intermediary layer;
c) inserting a needle through the piercing through the substrate layer, the intermediary layer and the outer skin layer to grasp a thread positioned on the outer skin layer;
d) pulling the thread through the outer skin layer, the intermediary layer and the substrate layer;
e) advancing the interior component to another position; and
f) repeating steps a-e until a predetermined amount of stitches are applied to the interior component.
16. The method as in claim 15 , wherein outer skin layer, is formed from one of the following; vinyl, leather and thermoplastic polyolefin; and the intermediary layer is a foam and the substrate layer is formed from plastic.
17. An interior component formed by the method of claim 16 , wherein the interior component is an interior trim piece of a vehicle.
18. The interior component of claim 17 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
19. An interior component formed by the method of claim 15 , wherein the interior component is an interior trim piece of a vehicle.
20. The interior component of claim 15 , wherein outer skin layer, is formed from leather and the intermediary layer is foam and the substrate layer is formed from plastic.
