Utility Vehicle Seat Rotation Layout for Low Structural Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility vehicle seats equipped with multiple adjustment modules are too tall, limiting their installation in smaller vehicles and making it difficult for smaller passengers to access and operate vehicle controls conveniently, thereby reducing their usability.
Innovation Solution
A utility vehicle seat design with a rotation adjustment device, longitudinal adjustment device, and transverse adjustment device, where the rotation adjustment apparatus is positioned between the rail units to minimize vertical extension, reducing the overall height and allowing for a more compact horizontal movement apparatus, thereby reducing the structural height by over 40% compared to existing solutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple seat adjustment modules (longitudinal, transverse, and rotation) are integrated into the seat substructure, then passenger comfort and adjustability are improved, but the overall height of the seat increases excessively
Solution Approach 1:
The patent combines the rotation adjustment device and longitudinal adjustment device into a single integrated horizontal movement apparatus. The rotation adjustment apparatus is positioned between the longitudinal rail units, merging previously separate adjustment modules into one compact structure that provides both rotational and longitudinal adjustment functions without requiring separate vertical space for each module.
Solution Approach 2:
The invention rearranges the spatial configuration of adjustment components by placing the rotation adjustment apparatus between the longitudinal rail units rather than stacking it vertically above or below them. This horizontal integration between rail units optimizes the use of available space and reduces the vertical footprint of the seat adjustment system.
2Adaptability or versatility
If the seat is designed with full adjustment modules for maximum comfort, then passenger comfort is improved, but the seat becomes too high for installation in smaller vehicles
Solution Approach 1:
The patent merges the rotation adjustment device with the longitudinal adjustment device into a single integrated horizontal movement apparatus. This combination eliminates the need for separate vertical stacking of adjustment modules, thereby reducing the overall structural height while maintaining all comfort features.
Solution Approach 2:
The rotation adjustment apparatus is positioned between the longitudinal rail units in a horizontal arrangement rather than vertically stacked. This dimensional reconfiguration allows full adjustment functionality to be achieved within a reduced vertical envelope suitable for smaller vehicles.
3Reliability
If traditional separate adjustment modules are used, then each adjustment function is reliable, but the overall device complexity and height increase
Solution Approach 1:
The patent combines multiple adjustment functions (rotation and longitudinal movement) into a single integrated horizontal movement apparatus with shared structural components. This merging reduces the number of separate adjustment modules while maintaining reliable adjustment functions through a unified, coordinated design.
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
The compact design allows for reduced overall height of the seat or increased space for vertical suspension, enhancing the usability of the seat in smaller vehicles and improving passenger access to controls.
Implementation Method 1
a rotation adjustment device comprising a roller body bearing unit for rotating at least the seat part about a vertical axis

AI summary
The invention relates to a utility vehicle seat with a seat part, with a backrest part and with a seat substructure for arrangement on a bodywork part of a utility vehicle. The seat substructure including a rotation adjustment device having a roller body bearing unit for rotating at least the seat part about a vertical axis, a longitudinal adjustment device and a transverse adjustment device. The rotation adjustment apparatus is arranged between two longitudinal rail units or transverse rail units, in such a way that a vertical extension of the rotation adjustment apparatus amounts to a maximum of 150% or 100% of a vertical extension of the longitudinal rail units or the transverse rail units.
