Seat Support Rubber Structure for Easier ATV Seat Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seat support structures for ATV vehicles face difficulties in assembly due to manufacturing errors between guide pins and mount rubbers, requiring excessive force for alignment and insertion, and are prone to play and removal issues.
Innovation Solution
A seat support structure where the mount rubber's insertion portion is moved radially within the seat support portion's opening, with the engaging groove's wall in pressure contact, allowing for easier assembly and secure seating without play, and featuring a larger body portion to prevent removal, and an inclined pin for easy insertion and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the diameter of the distal end portions of the mount rubbers is set larger than the diameter of the opening portions of the seat support portions, then the mount rubber can be prevented from falling out, but the insertion of the mount rubber requires excessive force
Solution Approach 1:
The mount rubber is divided into multiple sections with different diameters: a distal end portion with larger diameter for retention, an intermediate portion with smaller diameter for easy insertion through the opening, and an engaging groove portion. This segmentation allows each section to fulfill its specific function without compromising the others.
Solution Approach 2:
The engaging groove portion is formed as a nested structure within the mount rubber, creating an annular groove that engages with the seat support portion. This nested design provides additional retention mechanism without increasing the overall insertion force requirement.
2Reliability
If the diameter of the annular groove portions is set equal to the diameter of the opening portions of the seat support portions, then the mount rubber can be securely engaged, but the fitting requires excessive force
Solution Approach 1:
The mount rubber is segmented with the engaging groove portion having a different diameter configuration than the opening portion. The annular groove creates a stepped structure that allows engagement without requiring the entire mount rubber to be forced through the opening at full diameter.
Solution Approach 2:
The engaging groove portion is designed to be movable in the radial direction within the opening portion, allowing dynamic adjustment during assembly. This mobility enables the groove to engage securely while reducing the insertion force required.
3Manufacturing precision
If the guide pins and mount rubbers are aligned precisely, then the seat can be assembled accurately, but manufacturing errors cause misalignment making assembly difficult
Solution Approach 1:
The design changes the dimensional parameters of the mount rubber to include an intermediate portion with smaller diameter than the opening portion. This parameter change creates a tolerance buffer that accommodates manufacturing errors in guide pin and mount rubber positioning, allowing assembly to proceed easily despite dimensional variations.
Solution Approach 2:
The engaging groove portion is designed with radial movability within the opening portion, creating a dynamic adjustment capability. This allows the groove to self-align and accommodate manufacturing tolerances, making the assembly process more forgiving of precision errors.

Function Achieved in This Case
Facilitates easy seat mounting and assembly, ensures secure seating without play, prevents removal of the mount rubber, and allows for effective weight distribution during vehicle movement.
Implementation Method 1
a mount rubber (160) having an engaging groove portion (163) formed on an outer peripheral portion and a through hole (161) formed in a radially inside of the mount rubber (160), and a seat support portion (150) having an opening portion (151) formed in a front surface
Implementation Method 2
a portion of a groove wall of the engaging groove portion is brought into pressure contact with the opening portion

AI summary
A seat support structure for facilitating assembly of a frame support member. The seat support structure includes a seat support portion mounted on a seat rail of a vehicle, the seat support portion having an opening portion; a mount rubber having an engaging groove portion on an outer peripheral portion thereof, an insertion portion arranged closer to a distal end side than the engaging groove portion, and a through hole penetrating through the mount rubber. Upon mounting the seat, the insertion portion of the mount rubber is inserted into the opening portion of the seat support portion, the portion of the seat to be supported is inserted into the through hole, and the mount rubber is moved in the radial direction in an inside of the opening portion, and a portion of a groove wall of the engaging groove portion is brought into pressure contact with the opening portion.
