Vehicle Seat Track System for Stable Sliding Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat foundation systems fail to provide stable and smooth movement between slid-forward, slid-back, and medial configurations, leading to unintended deflection and reduced passenger comfort.
Innovation Solution
A track-support system is integrated into the seat foundation, comprising upper and lower support units, barriers, and a bearing system to minimize friction and maintain track alignment, allowing the vehicle seat to move smoothly between configurations while maximizing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional seat foundation system is used, then the structure is simple, but the seat movement is unstable and produces unintended deflection
Solution Approach 1:
The foundation system is divided into separate upper and lower track components that can move independently relative to each other. This segmentation allows each track to be optimized for its specific function while working together to provide stable seat movement without excessive deflection.
Solution Approach 2:
A bearing system is introduced as an intermediary component between the upper and lower tracks. This bearing system facilitates smooth relative movement while maintaining proper alignment and minimizing binding, thereby resolving the instability issue without requiring complete redesign of the entire foundation structure.
2Ease of operation
If friction is not minimized, then the structure is simpler, but the seat movement is not smooth and produces binding
Solution Approach 1:
A bearing system is introduced as an intermediary component between the upper and lower tracks. This bearing system facilitates smooth relative movement while maintaining proper alignment and minimizing binding, thereby resolving the instability issue without requiring complete redesign of the entire foundation structure.
Solution Approach 2:
The bearing system replaces direct mechanical contact between the upper and lower tracks with a rolling or sliding bearing interface. This substitution reduces friction and enables smoother movement while maintaining structural integrity.
3Reliability
If track alignment is not maintained, then the structure is simpler, but the seat movement produces binding and deformation
Solution Approach 1:
A bearing system is introduced as an intermediary component between the upper and lower tracks. This bearing system facilitates smooth relative movement while maintaining proper alignment and minimizing binding, thereby resolving the instability issue without requiring complete redesign of the entire foundation structure.

AI summary
A passenger support includes a vehicle seat and a foundation having a lower track and an upper track. The lower track is coupled to a floor of a vehicle in a fixed position relative the floor. The vehicle seat is coupled to the upper track to slide back and forth relative to the lower track.
