Movable Second-Row Center Seat to Increase Passenger Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-purpose vehicles, the fixed structure of second row seats positioned rearward of the driver seat leads to a narrow interval between passengers, causing shoulder collisions and discomfort.
Innovation Solution
A seat for a vehicle with a movable second row center seat on a partition wall, equipped with a locking device allowing leftward or rightward adjustment, including a lever bracket, locking lever, and locking grooves, to increase the interval between seats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second row center seat is fixed on the partition wall, then the structure is simple and stable, but the interval between left and right passengers is small causing shoulder collisions and discomfort
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed second row center seat into a movable one that can shift leftward and rightward along the partition wall. The seat is equipped with a locking device that allows it to be positioned at different locations and locked in place, enabling adjustment of the interval between left and right passengers to prevent shoulder collisions and improve comfort.
2Ease of operation
If the second row center seat is made movable to adjust the interval between seats, then passenger comfort is improved, but the structure becomes more complex with additional locking mechanisms
Solution Approach 1:
The patent applies the self-service principle through the locking device that enables the second row center seat to lock itself at selected positions. The locking mechanism includes a locking lever that can be manually operated to engage with locking grooves on the partition wall, allowing the seat to maintain its adjusted position without requiring additional complex active control systems.
3Adaptability or versatility
If a locking device is added to enable seat movement adjustment, then the seat can be repositioned to increase passenger interval, but the device complexity increases
Solution Approach 1:
The patent applies the segmentation principle by dividing the locking mechanism into discrete components: a locking lever, locking grooves positioned at different locations on the partition wall, and corresponding locking plates. This segmented approach allows the seat to be locked at multiple predetermined positions along the partition wall, providing position flexibility while keeping each individual locking component relatively simple in structure.

AI summary
A seat for a vehicle, includes a second row center seat and a second row side seat provided on a partition wall positioned rearward of a driver seat, the second row center seat may move leftward or rightward, and an interval between the seats may be increased in a state in which the second row center seat is moved in a right direction away from the second row side seat, which makes it possible to maximally prevent body contact between a passenger in the second row center seat and a passenger in the second row side seat.
