Pivoting Seat Mount With Adjustable Stops for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with fixedly mounted seats or standing plates transfer significant impact forces and vibrations to the driver, causing discomfort and potential damage, especially when driving on uneven surfaces or encountering obstacles, and existing damping solutions are inadequate for sudden impacts.
Innovation Solution
A device with a pivotally mounted seat or standing plate holder that includes adjustable vibration dampers and stops, allowing for free movement within adjustable limits, reducing the transfer of vibrations and impact forces to the driver by decoupling the frame's movements from the seat or plate, using components like flanges, vibration dampers, and stops to absorb and limit movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the seat or standing plate is firmly mounted to the frame, then the structural stability and strength are improved, but the driver is exposed to significant impact forces and vibrations from uneven surfaces
Solution Approach 1:
The patent introduces vibration dampers and stops as intermediary elements between the seat/standing plate and the frame. These intermediaries absorb and mitigate impact forces and vibrations while maintaining structural connection, resolving the contradiction between structural stability and driver comfort.
Solution Approach 2:
The patent incorporates vibration dampers that are pre-installed to cushion upcoming impacts before they reach the driver. This beforehand cushioning approach prepares the system to absorb shocks from uneven surfaces, kerbs, or obstacles before they transmit harmful forces to the driver.
2Object-affected harmful factors
If vibration dampers are added to reduce impact forces, then driver comfort is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple functions into integrated components. The vibration dampers are merged with the mounting structure, and stops are integrated into the same assembly, reducing the need for separate components and simplifying the overall device while maintaining vibration protection.
Solution Approach 2:
The patent allows adjustment of the damping characteristics and stop positions to optimize performance for different operating conditions. By enabling parameter adjustment, the system can be tuned to provide adequate protection without requiring overly complex multi-component systems for every scenario.
3Object-affected harmful factors
If the mounting device allows free movement to reduce vibration transfer, then driver comfort is improved, but the mounting strength and stability deteriorate
Solution Approach 1:
The patent creates a dynamic mounting system where the seat or standing plate can move relative to the frame through controlled degrees of freedom. This dynamic capability allows the system to absorb vibrations and impacts while maintaining secure mounting through the vibration dampers and stops that prevent excessive movement.

Function Achieved in This Case
This solution significantly reduces the transfer of vibrations and impact forces to the driver, providing improved comfort and safety by allowing the frame to move freely relative to the seat or plate, minimizing the risk of damage and enhancing the driving experience on uneven surfaces.

AI summary
The invention relates to a device (1) for mounting a seat (2) or a standing plate (25) relative to a frame (3) of a vehicle. The device comprises a seat holder (4) or a standing plate holder (4a) having at least one flange (7) extending laterally from the seat holder or the standing plate holder. The seat holder or the standing plate holder is pivotally mounted to the frame so that the frame and the seat holder or the standing plate holder can move relative to each other. The device has at least one first vibration damper (8) and/N or at least one stop (10) limiting the possible movement of the at least one flange thereby providing free movement until limits for the pivotal movement are met; these limits are adjustable. The device may also be provided with other kinds of vibration dampers (15, 18) designed and arranged to counteract that vibrations and movements of the frame during driving are transferred to the driver. Hereby a less damaging and more pleasant driving is obtained. The invention also relates to a vehicle with such a device.
