Recliner Attachment Bracket Composite Plate Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing recliner attachment brackets in vehicle seats, made of closed-section structural materials, face a trade-off between achieving necessary strength and weight reduction, as they tend to be heavy due to their structural requirements.
Innovation Solution
A recliner attachment bracket is designed using a combination of plate materials forming a closed-section structure, where two plate surfaces are joined by pressing, creating hollow sections and a flange portion, allowing for integral formation with the side frame or separate coupling, and employing methods like welding or adhesion to enhance strength while reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bracket is designed with high strength to attach the recliner, then the strength is improved, but the weight increases
Solution Approach 1:
The bracket is constructed using composite materials, specifically a combination of plate materials and closed-section structural materials. The plate materials provide the necessary strength for recliner attachment while the closed-section structures provide structural support with reduced weight, creating a composite bracket that balances strength and weight requirements
Solution Approach 2:
Different regions of the bracket are designed with different material properties and structural characteristics. The recliner attachment portion uses thick plate materials for high strength, while other portions use lighter closed-section structures, optimizing the weight-strength balance by applying material quality locally where needed
2Strength
If a closed-section structural material is used in the side frame, then the strength is improved, but the weight reduction is impeded
Solution Approach 1:
The side frame is constructed using composite materials, combining closed-section structural materials for strength-critical regions with plate materials for other portions. This composite construction allows the side frame to achieve necessary strength while reducing overall weight compared to using closed-section material throughout
Solution Approach 2:
The side frame is divided into multiple segments with different material compositions. The bracket portion uses a specific composite structure with plate materials, while other portions of the side frame may use different materials or structures, allowing optimized weight-strength balance across different functional regions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration secures necessary strength for the bracket while achieving weight reduction, prevents separation of plate materials, and reinforces the lower end with a rib structure, allowing for efficient attachment of the recliner and reducing the need for additional components.
Implementation Method 1
surfaces of two plate materials are joined to each other by pressing a central part of the closed-section structural material
Implementation Method 2
the plate materials the surfaces of which are joined to each other are coupled with each other so as not to be separated away in an overlapping direction

AI summary
A recliner attachment bracket includes a closed-section structural material having a recliner attachment portion. The recliner attachment portion is configured such that surfaces of two plate materials are joined to each other by pressing a central part of the closed-section structural material while hollow closed-section structures are left on both sides of the closed-section structural material. A lower end of the recliner attachment portion is constituted by only one of the plate materials.
