Removable Vehicle Seat Rail System with Anti-Rotation Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In minivans, the second row seats are difficult to remove and reconfigure due to their weight and the need to move or remove caps or carpeting, limiting cargo space and user functionality.
Innovation Solution
A rail and carrier system with sliding rails and strikers allows for easy reconfiguration of second row seats, including lateral sliding and removable options, with a lock mechanism and handle design for ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If second row seats are made removable to increase cargo space and configurability, then cargo space utilization and user functionality are improved, but the weight of the seat and complexity of removal/reinstallation operations worsen
Solution Approach 1:
The seat system is divided into modular components: the seat assembly, the rail system with multiple strikers, and the fastening mechanism. This segmentation allows the seat to be easily detached and reattached at different positions along the rail, improving both configurability and ease of operation.
Solution Approach 2:
The rail system incorporates multiple strikers at different positions along the rail length, allowing the seat to be dynamically repositioned to various locations. This dynamic positioning capability enables flexible configuration while maintaining ease of operation through a standardized attachment mechanism.
2Adaptability or versatility
If multiple strikers are provided for seat positioning to increase configurability, then seat position flexibility is improved, but device complexity and difficulty of operation worsen due to need to move caps or carpeting
Solution Approach 1:
Multiple strikers are integrated into a single continuous rail structure, eliminating the need for separate cap or carpeting components for each striker position. This merging of multiple positioning points into one unified system reduces overall device complexity while maintaining multiple seat position options.
Solution Approach 2:
The rail system serves multiple functions: it provides structural support for the seat, contains multiple strikers for positioning, and integrates all positioning mechanisms into a single accessible structure. This multi-functionality reduces the need for separate components like caps or carpeting, simplifying the overall system.
3Object-affected harmful factors
If strikers are covered by caps or carpeting to protect unused positions, then protection function is improved, but ease of operation worsens due to need to move or remove covers
Solution Approach 1:
The protective function is extracted from separate cap or carpeting components and integrated directly into the rail structure itself. The rail provides inherent protection for unused strikers while maintaining open access to all positions, eliminating the need for removable covers and improving ease of operation.

AI summary
A removable seat for a motor vehicle includes two hook fasteners for removably attaching the seat to front strikers that are rotatable about a lateral axis through the front strikers. A bar extends between the first hook fastener and the second hook fastener that is parallel to the lateral axis. The bar contacts the cover to prevent further rotation when the seat is rotated about the lateral axis to prevent over-rotation of the seat.
