AI Technical Summary

Technical Problem

Existing vehicle interior trim components with compressible 3D structures exhibit anisotropic haptic feedback, causing an unpleasant angular shift in the direction of the reaction force relative to the pressure force, contradicting user expectations for comfort and quality.

Method used

A vehicle interior trim component with a dual-layer comfort structure, where each layer contains flexible elongated elements oriented transversely or perpendicularly to the central plane, generating combined reaction forces that align with the pressure force direction, enhancing haptic feedback alignment and comfort.

Benefits of technology

The dual-layer design provides a more pleasant and higher-quality tactile experience by ensuring the haptic feedback direction aligns with the pressure force direction, improving user comfort and satisfaction.

Abstract

The present invention relates to an interior fitting or interior trim component of a vehicle, comprising a support layer (1), an appearance layer (2), and a first comfort layer (3) between the support layer (1) and the appearance layer (2). It also includes a second comfort layer (3') between the first comfort layer (3) and the support layer (1), wherein the first and second comfort layers each contain a compressible structure of flexible and / or soft elongated elements (3a, 3'a) and are configured to generate, in response to a compressive force applying to the two comfort layers, a first reaction force induced by the first comfort layer and a second reaction force induced by the second comfort layer, which combine to produce a resultant reaction force that is substantially aligned with or substantially parallel to the compressive force.
