Seat Backboard Trim Attachment With Hidden Fastener Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat designs with visible zippers for attaching trim covers to backboards detract from the appearance and are structurally challenging to hide the attachment point.
Innovation Solution
A seat design featuring a terminal member attached to the trim cover and a clip on the backboard, where the terminal member is connected to the clip in a manner that is covered by the trim cover, allowing the end of the trim cover to be fastened to the backboard without visible fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a zipper is used to connect the trim cover and backboard, then the attachment function is achieved, but the appearance is degraded due to visible zippers
Solution Approach 1:
The zipper connection mechanism is extracted and relocated to the rear side of the seatback, separating the functional attachment element from the visible front surface. The terminal member and connection member are positioned at the rear end, allowing the zipper to perform its fastening function while being completely hidden from external view by the trim cover and backboard structure.
Solution Approach 2:
The terminal member is inserted into a recess formed in the backboard, creating a nested structure where the connection components are housed within the backboard's rear surface geometry. This nesting arrangement conceals the attachment mechanism while maintaining structural integrity and attachment functionality.
2Shape
If the zipper is arranged at an invisible position, then the appearance is improved, but the structural arrangement becomes more difficult
Solution Approach 1:
The attachment structure transitions from a two-dimensional surface-level zipper arrangement to a three-dimensional configuration utilizing the depth and rear surface geometry of the backboard. The terminal member extends into the recess, and the connection member engages from the rear, creating a multi-layered attachment system that hides components through spatial arrangement rather than simple relocation.
Solution Approach 2:
The attachment system is segmented into distinct functional components: the terminal member attached to the trim cover, the recess in the backboard, and the connection member on the rear surface. This segmentation allows each component to be optimized for its specific function while collectively achieving the goal of hidden attachment without excessive overall complexity.

AI summary
Provided is a seat having an improved appearance by hiding a section where a trim cover is attached to a backboard from an outside. A seat includes: a seat pad; a backboard disposed on a back surface of the seat pad; a trim cover covering a front surface of the seat pad; a terminal member attached to the trim cover along an end thereof, and a connection member attached to an end of the backboard for connecting the terminal member thereto. The terminal member is connected to the connection member in a state where the terminal member and the connection member are covered with the trim cover from an outside, so that the end of the trim cover is fastened to the end of the backboard.
