Quick-Release Seat Locking Mechanism for Emergency Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat locking mechanisms do not allow for easy removal or interchange of seats during emergencies or for different usage scenarios, such as replacing a standard seat with a racing seat.
Innovation Solution
A seat mount system with a quick-release mechanism, including a cable-operated cam and sliding locking members, allows the seat to be removably attached to the vehicle frame, enabling easy removal and interchange by releasing the attachment shaft using a pull device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional locking device is used to secure the seat to the vehicle frame, then the seat remains firmly secured during normal operation, but the seat cannot be easily removed or interchanged during emergencies or for different usage scenarios
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic unlocked state through the operation of the release lever. The cam member can rotate between a locked position (where the cam surface engages the locking surface) and an unlocked position (where the cam surface disengages), allowing the system to adapt between secure attachment and easy removal based on operational needs
Solution Approach 2:
The cam member acts as an intermediary element between the release lever and the locking surfaces. When the release lever is actuated, it rotates the cam member, which then mediates the disengagement of the locking surfaces, providing a mechanical advantage that enables easy removal while maintaining secure attachment during normal use
2Adaptability or versatility
If a fixed locking mechanism is used, then the seat provides stable protection during accidents, but it obstructs emergency exit and prevents seat interchangeability
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: a cam member with a cam surface, a locking surface on the attachment shaft, and a release lever. This segmentation allows each component to perform its specific function independently, enabling the system to achieve versatility and ease of operation without excessive overall complexity
Solution Approach 2:
The cam member's geometry is designed so that rotation in one direction automatically engages the locking surfaces through the cam surface, while rotation in the opposite direction automatically disengages them. The mechanism serves itself by using the geometric properties of the cam surface to provide both secure locking and easy release without requiring complex control systems

AI summary
A vehicle seat system includes a seat having a base and an elongated shaft extending from the base. The system also includes a seat mount secured to a vehicle and configured to removably secured the seat to the vehicle. The seat mount has a body forming an inner cavity; a slide bar configured to slide within the cavity of the body; a spring disposed with the cavity and secured to the slide bar; a plurality of channels formed on a top surface of the body; a plurality of arms pivotally attached to the slide bar; a quick-release device configured to engage with the slide bar and configured to hold the slide bar in a fixed position; and a pull device connected to the quick-release device and configured to release the slide bar from the fixed position.
