Vehicle Seat Table Vertical Deployment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat tables that are accommodated in armrests tend to increase the armrest width, leading to space limitations for seat installation.
Innovation Solution
A table for a seat with a top plate and a leg member that can be moved from an accommodation position below the seat to a use position above it, utilizing a fixing device to secure the movement in conjunction with the top plate's operation, allowing the table to be efficiently stored without increasing the seat's width and easily deployed when needed.
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 close to the seat, but the armrest width increases and seat installation space is limited
Solution Approach 1:
The patent moves the table storage position from the horizontal dimension (armrest width) to the vertical dimension (below the sitting portion). The leg part extends downward to support the table body in the accommodation position, utilizing the vertical space under the seat rather than expanding the horizontal armrest width. This dimensional transition resolves the contradiction by preserving seat installation space while providing adequate table storage.
2Area of moving object
If the table is provided in sufficient size, then the table functionality is improved, but the seat width increases
Solution Approach 1:
The patent enables a sufficient-sized table by extending the support structure vertically downward rather than horizontally outward. The leg part with its movable portion and fixing device allows the table to achieve adequate surface area while maintaining the seat's original width by utilizing the vertical space below the sitting portion for table accommodation.
Solution Approach 2:
The patent employs a dynamic leg part that can transition between accommodation and use positions. The movable portion with fixing device allows the table to be compact during storage and fully extended for use, enabling sufficient table size without permanently increasing seat width. The dynamic configuration resolves the contradiction by providing size on demand rather than permanently.
3Ease of operation
If the table is easily deployed, then the operation convenience is improved, but the structural complexity increases
Solution Approach 1:
The patent implements a self-servicing deployment mechanism where the movable portion of the leg part automatically transitions between accommodation and use positions through its own structural design. The fixing device engages and disengages automatically during the movement process, eliminating the need for separate manual operations. This self-service approach improves ease of deployment while keeping the structural complexity manageable through automatic mechanical interaction.

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 movable portion, and a fixing device configured to fix a movement of the movable portion in conjunction with an operation of the top plate.
