Rear Seat Latch Pull Strap for Easy Fold-Down Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing latch mechanisms in pickup trucks are cumbersome and difficult to operate, requiring tools or modifications to access and release, especially when trying to fold down the rear seat, as the latch is often positioned in a hard-to-reach area.
Innovation Solution
A device comprising a latch pull bracket and webbing strap system that extends access to the latch without modifying factory components, allowing easy release of the seat back latch by pulling on a loop, which can be installed without tools and accommodates different latch pin configurations, including a keyhole feature for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a stock latch mechanism is used to maintain structural integrity, then the latch is positioned in a hard-to-reach area, but ease of operation deteriorates
Solution Approach 1:
A webbing strap with a loop acts as an intermediary tool that extends the user's reach to the latch mechanism. The strap is attached to the latch pin and can be pulled from above the seat, allowing operation without direct hand access to the confined space behind the seat while maintaining the stock latch's structural position.
Solution Approach 2:
The solution transitions the operation from a two-dimensional hand manipulation within the confined space to a one-dimensional pulling action along the webbing strap that extends outward from the latch area, allowing access from a different spatial dimension (above the seat rather than behind it).
2Ease of operation
If tools or modifications are used to access the latch, then ease of operation improves, but device complexity increases
Solution Approach 1:
The webbing strap is designed to be installed without tools by utilizing the existing latch pin structure. The strap can be attached by threading it through or around the latch pin, allowing the system to install and operate itself without requiring external tools or complex modification procedures.
Solution Approach 2:
The webbing strap is a simple, inexpensive component that can be easily replaced if needed. It serves as a temporary or permanent auxiliary element that adds minimal complexity while solving the accessibility problem, and can be discarded or replaced without affecting the core latch mechanism.

AI summary
A rear seat latch release device is easily installed to a portion of a rear seat holding mechanism so the rear seat can be released and more effectively folded down. The rear seat latch release device is specifically designed to surround the factory latch, and allow a pull strap to be added, which can more easily and effectively operate the rear seat latch. Components of the rear seat latch release device are designed to easily cooperate with several variations in the factory latch, thereby allowing installation in many different situations.
