Abstract

The present application relates to a method for fabricating a vehicle interior trim part. The proposed method comprises the step of providing a glass panel with a backside and a first and a second region. In a further step, a first stiffener is attached to the first region of the glass panel. Thereby, a stiffened region of the glass panel is formed. The method further comprises the step of bending the second region of the glass panel by cold forming so that a bent region of the glass panel is formed in a region adjacent to the stiffened region. The method further comprises the step of holding the glass panel in shape using a means of fixation.

First claim

We claim:

1. A method for fabricating a vehicle interior trim part, characterized by the steps:
providing a glass panel with a backside and a first and a second region,
attaching a first stiffener to the first region of the glass panel, thereby forming a stiffened region of the glass panel,
bending the second region of the glass panel by cold forming so that a bent region of the glass panel is formed in a region adjacent to the stiffened region, and
holding the glass panel in shape using a means of fixation.

2. The method of claim 1 , characterized by the step:
attaching a second stiffener to a third region of the glass panel, thereby forming a second stiffened region of the glass panel,
wherein the second stiffened region does not overlap with the first stiffened region, and
wherein the bent region is formed between the first stiffened region and the second stiffened region.

3. The method of claim 2 , characterized by the step:
attaching a third stiffener to a fourth region of the glass panel, thereby forming a third stiffened region of the glass panel,
wherein the third stiffened region does not overlap with the first stiffened region or the second stiffened region, and
wherein a second bent region is formed between the third stiffened region and the second stiffened region.

4. The method of claim 1 , characterized in that the means of fixation is a keystone stiffener, which has a surface with a curvature radius corresponding to a curvature radius of the backside of the glass panel in the bent region, and the step of holding the glass panel in shape comprises the following step:
arranging the keystone stiffener with its surface on the backside of the glass panel in the bent region.

5. The method of claim 1 , characterized by the step:
attaching a display to the backside of the glass panel in a region which corresponds to a stiffened region.

6. The method of claim 1 , characterized in that at least one of the stiffeners is a frame, which frame partially surrounds a region of the glass panel.

7. The method of claim 1 , characterized in that at least one of the stiffeners is a plate or a frame which at least partially covers a backside of the glass panel and/or a backside of the display.

8. The method of claim 1 , characterized in that the glass panel comprises an opening in a region corresponding to a stiffened region.

9. The method of claim 1 , characterized by the step:
removing a bending device after the step of holding the glass panel in shape, wherein the step of bending the glass panel by cold forming is performed using the bending device.

10. The method of claim 1 , characterized in that the stiffener contains a metal or a fibre reinforced plastic.
