Abstract

An equipment piece includes first and second components, such as a vehicle door armrest and a vehicle door. The first component is insertable in a recess, such as a slot, in the second component. The second component may be secured in the first by deformation of a projecting portion configured as a tab having a wall thickness smaller than its longitudinal extension. The tab is anchorable non-positively in the second component after inserting into the recess and pending about a longitudinal axis of the tab.

Claims

1. An equipment piece comprising:

a first and a second component for the interior of a vehicle, wherein the first component is made from a material comprising thermoplastic, and wherein the first component comprises a plurality of protrusions with projecting portions configured as tabs arranged in a linear manner, and the second component comprises a corresponding plurality of slots arranged in a linear manner;

wherein the plurality of tabs is configured to be inserted through the corresponding plurality of slots, and to be secured to the second component by deforming the projecting portion of each protrusion;

wherein each tab has a wall thickness (D) which is smaller than the longitudinal extension (B) of the tab, the plurality of tabs being anchorable non-positively in the second component after inserting through the corresponding plurality of slots by bending about a longitudinal axis (L) of each tab; and

wherein each tab is connected to the second component by a material connection formed by heating and melting adjacent regions of the first component and the second component.

2. The equipment piece as claimed in claim 1, wherein each tab may be brought to bear at least partially against surface of the second component.

3. The equipment piece as claimed in claim 1, wherein each tab has a wall thickness corresponding substantially to the wall thickness (d) of adjacent regions of the first component.

4. The equipment piece as claimed in claim 1, wherein the first component is an armrest and the second component is a support of a vehicle door.

5. A method for producing the equipment piece as claimed in claim 1, wherein at least one tab is heated before bending to soften the thermoplastic.

6. The method as claimed in claim 5, wherein each tab and each slot are made by punching out or laser cutting the first and second components.

7. The equipment piece as claimed in claim 1, wherein the material comprises a thermoplastic/fiber composite.

8. The equipment piece as claimed in claim 7, wherein the thermoplastic comprises polypropylene, and the fiber comprises natural fiber.
