Rotating Seat Frame Reinforcement for Collision-Stable Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seat frames in vehicles fail to stably satisfy load conditions such as collisions while allowing for both height adjustment and rotation.
Innovation Solution
A seat frame design incorporating a cushion part with a height-adjusting mechanism using rotating links, a rotating part reinforced by a connection bracket, and a reinforcing bracket part across spaced rails, which allows for stable load distribution and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat frame allows height adjustment and rotation, then the convenience for occupants is improved, but the stability under load conditions such as collisions deteriorates
Solution Approach 1:
The seat frame is divided into multiple functional segments: a rotating part for angular adjustment, a height-adjusting part with rotating links for vertical positioning, and a reinforcing bracket part for structural support. This segmentation allows each component to perform its specific function while maintaining overall stability during collisions.
Solution Approach 2:
The seat frame employs dynamic mechanisms including a rotating part with drive gears for angular adjustment and rotating links with cylindrical pins for height adjustment. These dynamic components enable the seat to adapt to occupant preferences while the reinforcing bracket ensures collision stability.
2Ease of operation
If rotating links are used for height adjustment, then the ease of height adjustment is improved, but the structural complexity increases
Solution Approach 1:
The height-adjusting part uses four rotating links (first and second rotating links on each side) connected by cylindrical pins, providing more linkages than the minimum required. This partial redundancy ensures smooth height adjustment while distributing mechanical loads across multiple connection points.

Function Achieved in This Case
The design effectively stabilizes the seat frame during collisions and enables smooth height adjustment and rotation, enhancing occupant safety and comfort.
Implementation Method 1
a height-adjusting part installed on a lower side of the cushion part and adjusting a height of the cushion part via a plurality of rotating links
Implementation Method 2
a rotating part installed below the height-adjusting part and rotating the height-adjusting part and the cushion part
Implementation Method 3
a reinforcing bracket part coupled to a lower side of the rotating part, reinforcing the rotating part
