Embodiment Construction

[0035] Decorative skin 1 in figure 1 shown in the section of . The decorative skin is a slush-molded skin of polyvinyl chloride (PVC) as a thermoplastic material. The decorative skin 1 is produced by a slush molding method, by which powder-like plastic is put into a slush mould, and the decorative skin 1 is molded by the effect of heating and rotating the slush mould. The decorative skin 1 is elastic and can be extended and bent to a large extent. The hardness of the decorative skin 1 is 68 Shore A, and its modulus of elasticity is 4 MPa. However, in a further embodiment, the decorative skin 1 can be formed in a rigid manner, so that its hardness can be greater than 68 Shore A.

[0036] The decorative skin 1 consists of a first part 2 and a second part 4, in figure 1 , the first part 2 is placed on the left side of the recess 3 and the second part 4 is in the figure 1 To the right of the center 3. Optionally, the decorative skin 1 can also be designed as a single part...

Abstract

The present invention relates to an internal trim part for a vehicle, comprising at least two layers. A decorative skin (1) forms an upper layer and has a depression (3), in which a decorative element (8) is arranged. The decorative element (8) is connected to the decorative skin (1) by means of a bonded connection, such as a weld seam, in particular an ultrasonic weld seam (16). The invention further relates to a method for producing an internal trim part and to a device for performing said method.

Description

technical field [0001] The invention relates to an interior trim part having a decorative skin comprising a recess in which a decorative arrangement is arranged, said decorative element being connected to the decorative skin by ultrasonic welding. The invention further relates to a method of fastening a decorative element that decorates a recess in a skin. Background technique [0002] The interior trim part of a car usually consists of several pieces connected to each other. One of these interior trim parts should be attached at an installed location as unnoticeable as possible within the vehicle; it should therefore be covered or concealed in another way to ensure such an interior trim part has a pleasing aesthetic. Typically, such attachment locations are placed in recesses on one side of the finished decorative skin, away from the viewer. Such a technology is derived, for example, from DE 10 2005 034 257 A1. This has the disadvantage that the narrowing of the recess i...
