Abstract

An interior door handle arrangement of a vehicle, includes a housing and an actuating section which is arranged on the housing, wherein the housing and/or the actuating section have/has a carrier section made from a first plastic and a visible section made from another, second material which is connected to the carrier section in an integrally joined manner. A method for producing such an interior door handle arrangement is also provided.

First claim

What is claimed is:

1. An interior door handle arrangement of a vehicle, comprising: a housing and an actuating section which is movably arranged on the housing, wherein the actuating section has a carrier section made from a first plastic and a decoration section made from a second plastic which is connected to the carrier section in an integrally joined manner, wherein the actuating section is configured with the decoration section and the carrier section molded together as a monolithic unit;
wherein the actuating section includes a rear side configured for facing toward a door in an installed state and a front side that is viewable from an interior of the vehicle in the installed state, wherein the decoration section forms the front side, and at least portions of the rear side are formed by the carrier section;
wherein the second plastic forms at least one convex edge or at least one convex arcuate portion of an external surface of the actuating section so that the second plastic extends around an in continuous bonded contact with a corner portion of the carrier section to the rear side of the actuating section such that a borderline region between the first plastic and the second plastic at the convex edge or convex arcuate portion is visible from the rear side of the actuating section, wherein the corner portion is formed by intersecting regions of a front facing surface portion of the carrier section and a side facing surface portion of the carrier section.

2. The interior door handle arrangement as claimed in claim 1 , wherein the carrier section comprises bearing means at the rear side of the actuating section, wherein in the unmounted but otherwise finished state of the actuating section, the first plastic is directly visible at a surface of the actuating section at least at the bearing means.

3. The interior door handle arrangement as claimed in claim 1 , wherein a portion of the surface of the rear side of the actuating section is formed by the second plastic extending from the front side of the actuating section towards the rear side of the actuating section forming said at least one convex edge or convex arcuate portion.

4. The interior door handle arrangement as claimed in claim 3 , wherein the portion of the second plastic extending from the front side of the actuating section towards the rear side of the actuating section forming said at least one convex edge or convex arcuate portion has at least a width of 5 mm.

5. The interior door handle arrangement as claimed in claim 4 , wherein the portion of the second plastic extending from the front side of the actuating section towards the rear side of the actuating section forming said at least one convex edge or convex arcuate portion extends over at least 25% of a border between the front side and the rear side of the actuating section.

6. The interior door handle arrangement as claimed in claim 5 , wherein at the location where the second plastic extends from the front side of the actuating section towards the rear side of the actuating section forming said at least one convex edge or convex arcuate portion, the actuating section has
a first tool split line at the border where the first plastic and the second plastic are bonded together, and
a second tool split line extending within the first plastic.

7. The interior door handle arrangement as claimed in claim 1 , wherein the decoration section has over at least 70% of its front side surface a constant thickness.

8. The interior door handle arrangement as claimed in claim 1 , wherein the decoration section has over at least 70% of its front side surface a thickness within the range of 0.5 mm and 3.5 mm.

9. The interior door handle arrangement as claimed in claim 1 , wherein the decoration section has over at least 70% of its front side surface a surface roughness Ra smaller or equal to 2 μm.

10. The interior door handle arrangement as claimed in claim 1 , wherein ferromagnetic metal particles is/are embedded into the first plastic.

11. The interior door handle arrangement as claimed in claim 1 , wherein the second plastic is at least partially transparent for visible light.

12. The interior door handle arrangement as claimed in claim 11 , wherein diffuser particles for diffusing visible light are embedded into the second plastic.

13. The interior door handle arrangement as claimed in claim 1 , wherein a thickness of the second plastic along the front facing surface portion of the carrier section is greater than a thickness of the second plastic along the side facing surface portion of the carrier section.
