Solution Overview
Problem
The existing vehicle seat designs with air passages and skin locking clips face issues where the skin locking clips disengage due to load, especially when embedded in thin portions of the pad, leading to instability and potential detachment of the skin material.
Innovation Solution
The design incorporates a pad with a main body member featuring a linear bulging portion and a surface layer member, where the skin locking clip is embedded in a thicker portion, and includes a linear shelf surface and side surfaces to securely position the intermediate and surface layer members, ensuring the clip is firmly embedded and prevents disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the skin locking clip is embedded in a thin portion of the pad to maintain appearance, then the aesthetic quality is improved, but the locking strength deteriorates causing disengagement under load
Solution Approach 1:
The invention transitions from a two-dimensional surface embedding to a three-dimensional embedded structure by creating a recess in the pad that extends into its thickness. The skin locking clip is positioned within this recess, utilizing the third dimension (depth) to achieve secure locking while maintaining a flush surface appearance. This dimensional transition allows the locking mechanism to be hidden within the pad's volume rather than protruding from or weakening the surface.
Solution Approach 2:
The skin locking clip is nested within a recess formed in the pad structure. The recess acts as a container that houses the locking clip, allowing it to be embedded within the pad's volume. This nesting arrangement provides structural support from the surrounding pad material while keeping the locking clip's locking surfaces accessible for securing the skin material, effectively hiding the mechanical components within the pad's interior space.
2Reliability
If the skin locking clip is embedded in the pad to secure the skin material, then the reliability is improved, but the device complexity increases due to additional pad structure
Solution Approach 1:
The recess is pre-formed in the pad during the pad manufacturing process, before the skin locking clip is installed. This preliminary preparation of the embedding space allows the locking clip to be subsequently positioned and secured without requiring complex post-assembly operations. The recess structure is created in advance as part of the pad's fabrication, simplifying the overall assembly process while ensuring proper positioning and support for the locking mechanism.

AI summary
A vehicle seat includes a pad having an air passage, a skin material, and a skin locking clip embedded in the pad and configured to tuck in a prescribed linear portion of the skin material. The pad includes a main body member in which the skin locking clip is embedded, an intermediate layer member arranged on the main body member, and a surface layer member arranged on the intermediate layer member. The main body member includes a linear bulging portion extending along the linear portion and bulging so as to define a plane substantially identical to a surface of the surface layer member, and the skin material is tucked in by the skin locking clip at a portion extending further from the surface layer member than the linear bulging portion.
