Pin-Biasing Assembly for Quick Vehicle Seat Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching a seatback frame to a vehicle frame are complex and require various welding and fastening operations, making them difficult to detach and reattach efficiently, especially in after-market repairs.
Innovation Solution
A pin-biasing assembly is used, where a pin is biased through a riser bracket and secured by a housing with a biasing spring, allowing slidable engagement with an angled channel to easily attach and detach the seatback frame, utilizing a pivot connection that can be operated manually without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding and fastening operations are used to attach the seatback frame to the vehicle frame, then the attachment strength and reliability are improved, but the device complexity and difficulty of detachment increase
Solution Approach 1:
The attachment mechanism is divided into separate functional components: a pin member with biasing means, a seatback frame with engagement features, and a vehicle frame with corresponding receptacles. This segmentation allows the system to achieve reliable attachment through modular components rather than complex integrated welding structures.
Solution Approach 2:
The pin member acts as an intermediary element between the seatback frame and vehicle frame. It provides the attachment function while incorporating biasing means to maintain engagement, eliminating the need for permanent welding connections and enabling easy detachment.
2Reliability
If welding and fastening operations are used to attach the seatback frame, then the attachment strength is improved, but the ease of repair and reattachment deteriorates
Solution Approach 1:
The attachment system transitions from a static welded connection to a dynamic mechanical connection. The biasing means continuously applies force to maintain pin engagement, allowing the seatback to be easily detached and reattached multiple times while maintaining secure attachment during use.
Solution Approach 2:
The biasing means automatically maintains pin engagement with the seatback frame and vehicle frame without requiring external fastening operations. This self-servicing mechanism ensures reliable attachment while enabling simple manual detachment by overcoming the biasing force, facilitating easy repair and reattachment.
3Ease of operation
If a pin-biasing assembly with spring is used, then the ease of operation for attachment and detachment is improved, but the device complexity increases
Solution Approach 1:
The pin member and biasing means are combined into a single integrated assembly that is mounted to the vehicle frame. This merging reduces the number of separate components and simplifies the overall structure while providing automatic engagement functionality that improves ease of operation.
Solution Approach 2:
The pin member serves multiple functions: it provides the mechanical connection between seatback and vehicle frame, incorporates the biasing mechanism to maintain engagement, and acts as the detachment point for manual operation. This multi-functionality reduces the need for additional components, balancing ease of operation with device complexity.

AI summary
A vehicle seat attachment includes a riser bracket of a vehicle frame. A pin is biased through the riser bracket to a securing position. A seat bracket has an angled channel that extends to a securing aperture, wherein slidable engagement of the angled channel with the pin is configured to bias the pin away from the securing position until the pin reaches the securing aperture wherein the pin returns to the securing position.
