Auxiliary Vehicle Seat Assembly With Motion-Locked Stowage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seating solutions in stationary vehicles lack flexibility and safety features, particularly in allowing auxiliary seating configurations that are not accessible or safe while the vehicle is in motion, limiting user convenience and potential future uses.
Innovation Solution
A seating assembly for vehicles that includes a primary seat with a backrest and an auxiliary seat base pivotably coupled to the backrest, featuring a locking mechanism and connection interface allowing the auxiliary seat to transition between stowed and deployed positions, with support legs and arms for enhanced stability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an auxiliary seat is provided in the vehicle, then seating versatility is improved, but safety risks increase when the vehicle is in motion
Solution Approach 1:
The auxiliary seat is designed with dynamic positioning capability, allowing it to be deployed or stowed based on vehicle operating conditions. The seat base can rotate between a deployed position (when vehicle is stationary) and a stowed position (when vehicle is in motion), enabling the system to adapt its configuration dynamically to balance versatility and safety requirements
2Ease of operation
If the auxiliary seat is made accessible during vehicle motion, then user convenience is improved, but safety risks increase
Solution Approach 1:
The system incorporates a sensor that detects vehicle motion and provides feedback to the control mechanism. When motion is detected, the locking mechanism is activated to secure the auxiliary seat in the stowed position, preventing access during vehicle motion and eliminating the need for user judgment about safety conditions
3Device complexity
If the auxiliary seat structure is simplified, then device complexity is reduced, but stability and safety features are compromised
Solution Approach 1:
The auxiliary seat is divided into functionally independent segments: a seat base with support legs, a seat back, and a locking mechanism. The support legs can deploy independently to provide stability, while the locking mechanism separately manages the deployed/stowed transitions. This segmentation allows each component to perform its specific function efficiently without unnecessary complexity

AI summary
A seating assembly for a vehicle includes a first seat including a first seat base coupled with a backrest. A second seat includes a seat back and a second seat base pivotably coupled with the seat back and moveable between a stowed position and a deployed position. A locking feature between the second seat base and the seat back is moveable between a locked position and an unlocked position. The locking feature engages the second seat base in the locked position. The locking feature is disengaged from the second seat base in the unlocked position. A connection interface between the backrest and the seat back includes an engaging member and a receiving member. The engaging member selectively engages the receiving member to secure the second seat to the first seat in an attached configuration.
