Rail Vehicle Driver Control Assembly Longitudinal Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail vehicle driver's cab configurations often compromise safety and comfort due to the need for adjustable seating and control elements, which can lead to impaired visibility and increased risk of control element damage, especially with varying driver body geometries.
Innovation Solution
A driver control arrangement where the operating element and armrest are part of a common assembly movable in the longitudinal direction, allowing adjustment to fit different driver geometries without compromising the control element's reliability, with an adjustment device that reduces friction and facilitates manual or motorized positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating element is integrated on the driver's seat and adjusted together with the seat in the longitudinal direction, then the driver can operate the control element comfortably according to body geometry, but the position of the operating element becomes vulnerable to damage and control lines may be damaged
Solution Approach 1:
The patent separates the operating element from the driver's seat, creating two independent adjustable components. The seat can be adjusted vertically and longitudinally, while the operating element is mounted on a separate adjustable support structure. This segmentation allows the control element to remain in a fixed, protected position while the seat adjusts to different driver body geometries, resolving the contradiction between ease of operation and reliability.
2Ease of operation
If the driver's seat is adjusted in the longitudinal direction to accommodate different body geometries, then the driver can reach the control element comfortably, but the driver's view of the surroundings is impaired
Solution Approach 1:
The patent implements multiple independent adjustment mechanisms that allow dynamic adaptation of both the seat and operating element positions. The seat can be adjusted vertically and longitudinally, while the operating element support can be adjusted independently in the longitudinal direction. This dynamic adjustment system enables the driver to achieve both comfortable control element accessibility and optimal viewing position simultaneously, resolving the contradiction between ease of operation and visibility.
3Ease of operation
If the operating element is permanently installed to the left of the driver's seat, then the control element is easily accessible, but drivers with certain body geometries cannot maintain both comfortable control and clear view of surroundings
Solution Approach 1:
The patent transforms the fixed operating element position into a dynamically adjustable position through a separate longitudinal adjustment mechanism for the operating element support. This allows the control element to be repositioned along the longitudinal axis to accommodate different driver body geometries, while the seat simultaneously adjusts to provide optimal viewing position. This resolves the contradiction between ease of operation and adaptability to different body geometries.

AI summary
The arrangement has a control lever (6) for manual control by a driver to control a drive system and/or a brake system of a rail vehicle. An armrest (5) of a driver seat, is provided for placing lower arms of the driver. The control lever and the armrest are provided as parts of a common assembly (4). The common assembly is moved in a driving direction (F) so that longitudinal positions (6a-6c) of the common assembly are adjusted in the direction. The control lever and the armrest are arranged relative to each other so that the control lever is controlled by a hand of the driver. An independent claim is also included for a method for adjusting a rail vehicle-driving cab to body geometry of a driver.
