Vehicle Seat Cushion Support Joint Structure for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cushion support members for vehicle seats face challenges in distributing loads evenly when reinforcements intersect, leading to potential concentration of load at angular joints, and in efficiently arranging hooks and staples for cover material fixation without increasing the structure's size.
Innovation Solution
The cushion support member incorporates a joint design where reinforcements intersect and are joined with curved join lines, and a back surface with a hole to prevent thickness increase and weight reduction. Additionally, the member features a load-receiving part and beads strategically positioned to enhance rigidity and distribute loads effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple reinforcements are arranged to cross each other to reinforce the cushion support member, then the reinforcement effect is improved, but load concentrates at the angular joint making it difficult to distribute
Solution Approach 1:
The patent applies curvature by forming the joint surface with curved join lines instead of angular intersections. The curved join lines allow load to be distributed smoothly along the curve rather than concentrating at sharp angles, while still providing effective reinforcement where the reinforcements intersect
2Reliability
If hooks and staples are arranged in the direction where cover material can be pulled toward upper surface, then fixation reliability is improved, but spaces for arranging hooks and staples are required increasing structure size
Solution Approach 1:
The patent resolves the spatial conflict by arranging hooks and staples in different dimensional planes. Hooks are arranged in a first direction while staples are arranged in a second direction that crosses the first direction, allowing both fixation methods to be implemented without requiring additional space in the pulling direction

AI summary
A structure of a cushion support member including reinforcements and a joint at which the reinforcements intersect and are joined together. The reinforcements include a first reinforcement, a second reinforcement and a third reinforcement extending respectively in a first direction, a second direction adjacent to the first direction, and a third direction adjacent to the second direction. The joint has a surface showing a first join line indicating a joined part of the first and second reinforcements and a second join line indicating a joined part of the second and third reinforcements. The first and second join lines are formed of curved lines curving from one side to the other side in a thickness direction of the cushion support member, and an end of the first join line and an end of the second join line meet at a same position on the one side.
