Vehicle Seating Assembly Turntable Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seating assemblies lack the necessary adjustability and flexibility to accommodate diverse user preferences and configurations, particularly in vehicles, where additional adjustability is desired for improved user experience and functionality.
Innovation Solution
The seating assembly incorporates a rotatable turntable with a slidable and pivotable seatbase, allowing for movement in multiple directions and configurations, including parallel and non-parallel sliding and pivoting, to accommodate various seating positions such as forward-facing, side-facing, and rear-facing orientations, enhancing adjustability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional seating assemblies are used with only fore and aft adjustment, then the structure is simple, but the adjustability and flexibility are insufficient
Solution Approach 1:
The seating assembly is divided into multiple independently adjustable components: a turntable assembly for rotational movement, a seatbase assembly for sliding and pivoting, and a seat assembly. Each component can be adjusted independently, providing comprehensive adaptability while managing complexity through modular design
Solution Approach 2:
The seating assembly transitions from a static structure to a dynamic one with multiple degrees of freedom. The turntable provides rotational adjustment about a vertical axis, the seatbase provides sliding adjustment along tracks, and pivoting capability, allowing the seating position to be dynamically adapted to various user needs and configurations
2Adaptability or versatility
If additional adjustability is added to the seating assembly, then user experience is improved, but the device complexity increases
Solution Approach 1:
The turntable assembly serves multiple functions: it enables rotational adjustment of the entire seatbase and seat assembly, provides a mounting platform for the seatbase, and allows for configurable orientations (forward-facing, side-facing, rear-facing). This multi-functionality reduces the need for separate mechanisms for each adjustment type
Solution Approach 2:
The seatbase acts as an intermediary component between the turntable and the seat assembly. It receives rotational movement from the turntable and provides additional sliding and pivoting adjustments, mediating the complex motions to achieve the desired seating configurations while maintaining a manageable mechanical structure

AI summary
A seating assembly includes a turntable that is rotatable about a first vertical axis. A seatbase is slidably coupled to the turntable. The seatbase is configured to slidably actuate regardless of a rotational position of the turntable. The seating assembly may be installed in a vehicle.
