Vehicle Seat Table With Biased Leg Mechanism for Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat tables that are accommodated in armrests tend to increase the width of the armrest, leading to space limitations for seat installation.
Innovation Solution
A table for seat with a top plate and leg member system that includes a first leg part rotatably connected to a support portion and a second leg part, where the second leg part is biased by a biasing member to move the table from an accommodation position below the seat to a use position above the seat, allowing efficient space utilization without widening the seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the table body is accommodated in the armrest, then the table can be stored when not in use, but the armrest width increases and seat installation space is limited
Solution Approach 1:
The patent relocates the table storage location from the horizontal armrest space to the vertical space beneath the seat. The table is stored in the depth direction under the seat cushion rather than widening the armrest horizontally, utilizing the unused vertical volume under the seat to resolve the space conflict.
Solution Approach 2:
The table is nested within the space under the seat cushion, fitting into the available volume beneath the sitting portion. This nesting approach allows the table to be stored within the seat assembly without increasing the external dimensions of the seat or armrest.
2Ease of operation
If the table is positioned above the sitting portion for use, then accessibility is improved, but the mechanism complexity increases
Solution Approach 1:
The leg part is divided into multiple segments (first leg part and second leg part) that can rotate independently relative to each other. This segmentation allows the table to be deployed in stages, improving accessibility while keeping each individual rotational joint simple and easy to operate.
Solution Approach 2:
The leg part employs a dynamic multi-stage rotation mechanism that transitions the table from a stored position under the seat to a usable position above the sitting portion. The first and second leg parts rotate sequentially to achieve the final elevated position, providing ease of operation through controlled motion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the provision of a sufficient-sized table without narrowing the seat width, allowing easy operation and reducing space restrictions under the seat, while preventing excessive vibration noise during vehicle travel.
Implementation Method 1
a biasing member disposed between the support portion and the second leg part to apply a biasing force to the second leg part from the support portion

AI summary
A table for seat provided facing a seat installed above a floor of a vehicle, including a top plate, and a leg part attached to a support portion provided below the seat to movably support the top plate from an accommodation position below the sitting portion to a use position above a sitting portion of the seat. The leg part includes a first leg part rotatably connected to the support portion, and a second leg part having a first end rotatably connected to the first leg part and a second end rotatably connected to the top plate. The table for seat further includes a biasing member disposed between the support portion and the second leg part to apply a biasing force to the second leg part from the support portion.
