Vehicle seat comprising an adjustment device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats with operator devices often have mechanically separate adjustment mechanisms for seat position and operator device placement, making it difficult to access and adjust the operator device, especially when seated.
Innovation Solution
A vehicle seat with an adjustment device featuring an axis of rotation and a pivotable shaft connected to the operator device, allowing for simple manual or automatic adjustment of the operator device's vertical position and tilt relative to the seat, using a guide link with arc-shaped and triangular elements for secure pivoting and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator device is mechanically separated from the seat adjustment device and arranged on the side of the seat, then the operator device can be independently positioned, but it becomes difficult to access and adjust when the operator is seated
Solution Approach 1:
The patent merges the operator device with the seat adjustment mechanism by connecting the operator device to the shaft that adjusts seat position. This integration allows the operator device to move together with the seat, maintaining accessibility while preserving independent positioning capability. The operator device is coupled to the shaft through a connection that allows relative movement, combining the benefits of both separate positioning and integrated adjustment.
2Ease of operation
If the operator device is integrated with the seat adjustment mechanism, then accessibility is improved, but the ability to independently position the operator device is reduced
Solution Approach 1:
The patent implements a dynamic connection between the operator device and the shaft, allowing the operator device to move relative to the shaft within certain limits. This dynamic coupling enables the operator device to follow the seat's movement for improved accessibility while still allowing independent positioning adjustments through the guide link mechanism that constrains but does not fully fix the relative position.
3Adaptability or versatility
If a complex adjustment mechanism is used to allow both vertical and longitudinal adjustment of the operator device, then positioning flexibility is improved, but the device becomes more expensive and complicated
Solution Approach 1:
The patent makes the shaft and its associated adjustment mechanism serve multiple functions: it adjusts both the seat position and the operator device position simultaneously. The guide link mechanism, originally designed for seat adjustment, is adapted to also control operator device positioning. This multi-functionality reduces the need for separate adjustment mechanisms, lowering complexity and cost while maintaining positioning flexibility.

AI summary
The invention relates to a vehicle seat comprising an operator device arranged at the side for operating vehicle seat and/or vehicle functions, and an adjustment device for adjusting a vertical position and/or a tilt level of the operator device with respect to the rest of the vehicle seat, wherein the adjustment device comprises an axis of rotation extending in the seat width direction, and a shaft which is connected to the operator device, is spaced apart from the axis of rotation and arranged so as to be pivotable about said axis together with the operator device.
