Vehicle Seat Cover Structure for Concealed Fastener Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat cover structures with separately formed parts joined by a joining unit tend to expose fastener pieces, leading to a deterioration in appearance due to peeling and exposure of the fastener pieces.
Innovation Solution
A vehicle seat cover design featuring a band-shaped covering member in an annular shape with ends overhanging inwardly, containing an inserting structure for a string-shaped member that, when tightened, covers the joining unit, ensuring it remains concealed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If fastener pieces are sewn onto cover pieces and end edge portions are folded back to cover the fastener pieces, then the appearance is improved, but the overhanging portion easily peels off and the fastener pieces are exposed, deteriorating the appearance
Solution Approach 1:
The covering member is divided into a first covering portion and a second covering portion that are separately formed and can be joined and separated. This segmentation allows the covering member to be easily mounted and removed while maintaining appearance when joined, and enables reliable coverage stability when the portions are properly engaged through the joining unit.
Solution Approach 2:
The first and second covering portions are nested together through the joining unit (slide fastener), with one portion inserted into the other. This nesting structure ensures that when joined, the covering portions maintain a unified appearance while the interlocking mechanism provides reliable coverage stability preventing peeling.
2Ease of operation
If separately formed parts are joined by a joining unit, then the seat cover can be easily mounted, but the joining unit exposes fastener pieces and deteriorates appearance
Solution Approach 1:
The covering member acts as an intermediary element that conceals the joining unit (slide fastener) between the first and second cover portions. When the covering member is in place, it mediates the visual appearance by hiding the fastener pieces, while still allowing the joining unit to function for easy mounting and removal.
Solution Approach 2:
The covering member is formed as a flexible band-shaped structure that can be disposed around the joining unit. This flexible thin film structure conforms to the shape of the joining unit while concealing it, maintaining appearance without interfering with the ease of operation of the joining unit.
3Shape
If the covering member is disposed in an annular shape with inward overhang, then the joining unit is covered, but the structure complexity increases
Solution Approach 1:
The covering member serves multiple functions: it conceals the joining unit to maintain appearance, provides structural reinforcement around the joining area, and works with the joining unit to enable easy mounting and removal. This multi-functionality justifies the increased structural complexity by delivering multiple benefits from a single component.

AI summary
A vehicle seat cover including separately formed parts that are configured to wrap a seat main body and are joined by a joining unit, wherein a band-shaped covering member, which can visually cover a joining state by the joining unit, is disposed in an annular shape, the covering member provided to overhang in an inner side direction of the annular shape, wherein the joining unit is disposed in an inner side position of the annular shape of the covering member along a position in which the covering member is disposed, and wherein in the covering member, an inserting structure is formed into which a string-shaped member can be inserted into a part that overhangs in the inner side direction of the annular shape along an longitudinal direction of the covering member, and the string-shaped member inserted into the inserting structure is tightened.
