Vehicle Seatback Bracket Alignment Guide Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing seatback fastening structures in vehicles are inefficient due to the difficulty in positioning seat and body brackets without a clear view, leading to decreased work efficiency during installation.
Innovation Solution
The proposed seatback fastening structure includes seat and body brackets with planar guide portions and a seat auxiliary bracket, allowing easier alignment and positioning even when the brackets are not visible, by using retaining and side walls as guides in the up-down and left-right directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the diameters of holes in brackets are enlarged to facilitate positioning, then the ease of operation improves, but the strength of the brackets deteriorates
Solution Approach 1:
The bracket positioning function is segmented into two independent components: guide portions for alignment and holes for fastening. The guide portions provide positioning surfaces that enable easy alignment without enlarging the fastening holes, thus maintaining bracket strength while improving ease of operation.
2Ease of operation
If the brackets are made visible to the worker, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
Guide portions act as intermediary elements between the brackets and the worker. These guide portions provide tactile feedback and visual references for positioning without requiring the entire bracket structure to be visible or complex, thus improving ease of operation while minimizing added complexity.

AI summary
One aspect of the present disclosure provides a seatback fastening structure for fastening a seatback to a body of a vehicle. A body bracket includes a main body portion covered by a seat bracket. The main body portion includes a receiving surface, an upper surface extending from a vertical upper end of the receiving surface, and a first lateral surface and a second lateral surface extending from both ends of the receiving surface in a width direction. The seat bracket includes a base portion covering the receiving surface, a retaining portion retaining the upper surface from vertically above, a first side wall and a second side wall respectively abutting on the first lateral surface and the second lateral surface. The main body portion and the base portion are fastened with a bolt.
