Vehicle seat and assembling method therefor
Find Innovative SolutionsGenerate Solutions
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
1Reliability
If the skin locking clip is embedded in a thin portion of the pad to maintain appearance and air passage functionality, then the air passage can be formed and appearance maintained, but the skin locking clip cannot withstand the load and may disengage from the pad
Solution Approach 1:
The pad is designed with localized thick portions that provide increased thickness specifically at the embedding locations of the skin locking clips, while other portions of the pad maintain their original thin profile to ensure air passage functionality and appearance. This local quality enhancement allows the skin locking clips to be embedded in thick portions with sufficient load-bearing capacity while the overall pad structure remains optimized for ventilation and aesthetics.
2Reliability
If the pad structure is modified to include thick portions for secure clip embedding, then the skin locking clip stability is improved, but the pad structure becomes more complex
Solution Approach 1:
The thick portions are integrated into the existing multi-layer pad structure by combining the functional requirements of structural support and clip embedding. The thick portions serve dual purposes: providing mechanical support for the skin locking clips and maintaining the overall integrity of the pad structure. This merging approach avoids adding separate complex support structures while achieving secure clip retention.
3Shape
If the skin locking clip is embedded in the thin surface layer portion to maintain appearance, then the appearance is maintained, but the clip may disengage under load
Solution Approach 1:
The pad structure is designed with localized thick portions positioned specifically at the embedding locations of the skin locking clips, while the overall surface profile and other portions of the pad maintain their original thin design for appearance and air passage functionality. This selective thickening ensures that the clips are embedded in structurally sound areas without compromising the aesthetic appearance of the pad surface.

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.
