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 an awl to form a piercing therethrough; b) retracting the awl from the outer skin layer, the substrate layer and the intermediary layer; c) inserting a needle of a robotic sewing head 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) looping the thread with a previous stitch passed through the outer skin layer, the intermediary layer and the substrate layer; f) advancing the robotic sewing head to another position with respect to the interior component, wherein a backside of the substrate layer is free of obstructions; and g) repeating steps a-f 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 to form a piercing therethrough;
b) retracting the awl from the outer skin layer, the substrate layer and the intermediary layer;
c) inserting a needle of a robotic sewing head 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) looping the thread with a previous stitch passed through the outer skin layer, the intermediary layer and the substrate layer;
f) advancing the robotic sewing head to another position with respect to the interior component, wherein a backside of the substrate layer is free of obstructions; and
g) repeating steps a-f 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 the group consisting of vinyl, leather and thermoplastic polyolefin; and the intermediary layer is a foam and the substrate layer is formed from plastic.
3. The method of claim 2 , wherein the interior component is an interior trim piece of a vehicle.
4. The method of claim 3 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
5. The method of claim 1 , wherein the interior component is an interior trim piece of a vehicle.
6. The method 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 method of claim 1 , wherein the backside of the substrate layer is free of obstructions along the entire stitch length.
9. The method of claim 8 , wherein the interior component is an interior trim piece of a vehicle.
10. The method of claim 9 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
11. 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 method of claim 11 , wherein the interior component is an interior trim piece of a vehicle.
13. The method of claim 12 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
14. The method 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 an awl to form a piercing therethrough;
b) retracting the awl from the outer skin layer, the substrate layer and the intermediary layer;
c) inserting a needle of a robotic sewing head 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) looping the thread with a previous stitch passed through the outer skin layer, the intermediary layer and the substrate layer;
f) advancing the robotic sewing head to another position with respect to the interior component, wherein a backside of the substrate layer is free of obstructions; and
g) repeating steps a-f 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 the group consisting of vinyl, leather and thermoplastic polyolefin; and the intermediary layer is a foam and the substrate layer is formed from plastic.
17. The method of claim 15 , wherein the interior component is an interior trim piece of a vehicle.
18. The method of claim 17 , wherein the interior trim piece is a portion of an instrument panel of the vehicle.
19. The method as in claim 18 , wherein outer skin layer, is formed from the group consisting of vinyl, leather and thermoplastic polyolefin; and the intermediary layer is a foam and the substrate layer is formed from plastic.
