Multi-Pivot Foldable Vehicle Seat for Flat-Floor Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats lack flexibility in configuration, limiting their functionality and space utilization in vehicles.
Innovation Solution
A motor vehicle seat design with multiple pivot points and adjustable components, allowing it to be folded into different positions such as a table or flat floor, and an easy entry position, facilitated by actuators and tilt adjustment devices for seamless transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the backrest is made fixed and non-foldable, then the structural integrity and stability are improved, but the versatility and space utilization are worsened
Solution Approach 1:
The backrest is designed with dynamic characteristics, allowing it to pivot between an upright position for seating and a folded position for creating flat surfaces. The pivot connection enables the backrest to transition between fixed and movable states, providing both structural stability when needed and versatility when folded.
Solution Approach 2:
The backrest serves multiple functions: it provides back support when upright and creates a flat surface when folded. This multi-functionality allows the seat to adapt between different usage scenarios, enhancing versatility without compromising the basic seating function.
2Adaptability or versatility
If the backrest is made foldable to increase versatility, then the adaptability and space utilization are improved, but the structural integrity and stability are worsened
Solution Approach 1:
The pivot connection allows the backrest to dynamically adjust between upright and folded positions while maintaining structural integrity through a secure mechanical connection that prevents unwanted movement during operation.
Solution Approach 2:
The backrest is segmented from the seat base through the pivot connection, allowing independent movement of the backrest while maintaining a secure connection. This segmentation enables folding functionality without compromising the overall structural integrity of the seat assembly.
3Adaptability or versatility
If multiple pivot points and adjusting devices are added to enable folding positions, then the versatility and functionality are improved, but the device complexity is worsened
Solution Approach 1:
The folding mechanism is segmented into distinct pivot points: one between the backrest and seat base, and another between the backrest and headrest. This segmentation allows each component to pivot independently, achieving multiple positions without requiring complex interconnected adjustment mechanisms.
Solution Approach 2:
The seat employs dynamic pivot connections that allow automatic adjustment to different positions based on the force applied, eliminating the need for complex locking mechanisms or motors. The pivot points naturally settle into stable positions, simplifying the overall device complexity.

AI summary
A vehicle seat comprises an underframe; a backrest with a backrest frame; and a flange on each side of the backrest. Each flange is mounted so as to pivot relative to the backrest frame about a first transverse axis, and relative to the underframe about a second transverse axis.
