Vehicle Seat Trim Assembly Alignment via Segmented Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching trim assemblies to vehicle seat members often struggle to align linear elements on the seating surface with underlying grooves, leading to aesthetic issues and potential sagging or bagginess.
Innovation Solution
A trim assembly design featuring a first and second trim member with strategically positioned apertures, folds, and seams allows for precise alignment and attachment using fasteners or hook and loop fasteners, ensuring secure and aesthetically pleasing integration with the seat member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional methods are used to attach trim assemblies to vehicle seat members, then the attachment process is simple, but the alignment between linear elements on the seating surface and underlying grooves is poor, causing aesthetic issues and potential sagging
Solution Approach 1:
The trim assembly is divided into multiple trim members (first trim member, second trim member, third trim member) that can be separately attached to different regions of the seat member. Each trim member has its own set of apertures positioned to align with specific grooves, allowing independent positioning and precise alignment without requiring a single complex attachment structure.
Solution Approach 2:
The apertures are pre-positioned in each trim member during manufacturing to correspond with the locations of grooves on the seat member. This preliminary positioning ensures that when the trim members are attached, the linear elements will automatically align with the grooves, eliminating the need for complex alignment procedures during assembly.
2Reliability
If multiple trim members are used with apertures and folds for precise alignment, then aesthetic appearance and secure attachment are improved, but the manufacturing and assembly process becomes more complex
Solution Approach 1:
The trim assembly is segmented into multiple independent trim members that can be manufactured separately using standard fabrication processes. Each trim member contains apertures and folds that are created during individual manufacturing, allowing for reliable attachment to the seat member while maintaining ease of manufacture through modular production rather than requiring a single complex piece.
Solution Approach 2:
The trim members are constructed from flexible materials that can be folded and shaped to conform to the contours of the seat member. The folds in each trim member allow the material to flex and adapt to the underlying surface, ensuring secure attachment and preventing sagging while maintaining aesthetic appearance. This flexibility is achieved through standard fabric or vinyl materials and folding techniques.
3Manufacturing precision
If the second trim member has side regions extending into grooves with multiple apertures, then alignment and secure attachment are improved, but the trim member design becomes more complex
Solution Approach 1:
The second trim member is segmented into distinct regions: a central region and two side regions. The side regions extend into the grooves and contain series of apertures positioned to align with groove locations. This segmentation allows each region to serve a specific function - the central region connects to the first trim member while the side regions provide secure attachment to the seat member, achieving precise alignment without requiring an overly complex monolithic design.
Solution Approach 2:
The second trim member is designed to perform multiple functions simultaneously: it connects to the first trim member through its central region, attaches to the seat member through its side regions in the grooves, and provides structural support. The series of apertures in the side regions serve both alignment and attachment purposes, reducing the need for separate alignment features and simplifying the overall design while maintaining precision.

AI summary
A trim cover assembly for a vehicle seat assembly, a vehicle seat assembly, and a method of assembling the trim cover are provided. The trim cover assembly has a first trim member with a first surface to form a seating surface and a second surface opposite to the first surface. A second trim member is provided for connection to a seat member, and has first and second side regions each extending between first and second end regions. The first and second end regions are connected adjacent to first and second edges of the first trim member, respectively. A central region of the second trim member is connected to the second surface of the first trim member via a first seam.
