Vehicle Seat Guide Frame Reinforcing Profile Force Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat vertical suspension systems face inefficiencies in force transfer due to weak interfaces between components, limiting comfort and load-bearing capacity, especially under dynamic conditions.
Innovation Solution
A lower guide frame with a reinforcing profile that extends along the guide rail, featuring a channel shape for efficient force diversion and a mirror-inverted design for symmetric force introduction, allowing for the use of high-strength materials and reduced material thickness, along with a lever arrangement connecting the guide frames for enhanced structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If additional check profiles and reinforcing profiles are added to improve force transfer, then force transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines the reinforcing profile and guide rail into a single integrated component. The guide rail serves dual functions: providing structural reinforcement and guiding the sliding seat. This integration eliminates the need for separate reinforcing profiles while maintaining force transfer efficiency, directly resolving the contradiction between strength improvement and device complexity reduction.
2Strength
If separate reinforcing profiles are mounted on guide rails, then load-bearing capacity is improved, but material usage increases
Solution Approach 1:
The guide rail is designed as an integrated structure that combines the reinforcing function with the guiding function. By incorporating reinforcement elements directly into the guide rail geometry rather than adding separate components, the patent achieves improved load-bearing capacity while minimizing additional material usage.
Solution Approach 2:
The guide rail serves multiple functions simultaneously: it provides structural reinforcement, guides the sliding seat movement, and transfers forces. This multi-functionality eliminates the need for dedicated reinforcing components, reducing overall material usage while maintaining load-bearing capacity.
3Strength
If the reinforcing profile uses larger material thickness, then force transfer efficiency is improved, but weight increases
Solution Approach 1:
The guide rail incorporates localized reinforcement features at specific critical sections where force transfer is most needed, rather than uniformly increasing material thickness throughout. This allows optimal force transfer efficiency at key interfaces while minimizing overall material usage and weight.
Solution Approach 2:
The patent utilizes composite structural designs in the guide rail, combining different material properties or structural configurations to achieve high strength-to-weight ratio. This enables effective force transfer without proportionally increasing weight.

AI summary
A lower guide frame for a vertical suspension system of a vehicle seat having a left-hand slide and, parallel thereto, a right-hand slide which are connected to each other via a lower crosspiece. Attached to an upper side of at least one slide is a reinforcing profile which has a horizontal portion, via which it is connected to the upper side of one slide, and adjoining the horizontal portion is an oblique portion that is oriented obliquely downwards and outward. Adjoining the oblique portion is a vertical portion that, in the assembled state, extends to just above a vehicle floor.
