Motorcycle Seat Height Link Cover for Dust and Water Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyance seat devices with saddle-type seats, particularly for motorcycles, face challenges in protecting the seat height adjustment unit components from external foreign matter such as dust and dirt, especially when exposed to wind and rain.
Innovation Solution
A conveyance seat device with a flexible cover member that encases the rotation link and support members, allowing for protection from all directions and easy operation, including a polyhedron-shaped cover member that changes shape with seat movement and includes overhanging portions to prevent interference during vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat height adjustment unit components are exposed to enable operation, then ease of operation is improved, but protection from foreign matter deteriorates
Solution Approach 1:
A flexible cover member made of elastic material is used to cover the rotation link and other components of the seat height adjustment unit. The cover can elastically deform to accommodate the rotational movement of the rotation link while maintaining continuous coverage, thus protecting components from foreign matter while allowing operation.
Solution Approach 2:
The cover member is designed with dynamic characteristics, allowing it to elastically expand and contract as the rotation link moves. This dynamic flexibility ensures the cover remains intact during operation without requiring rigid structures that would impede movement.
2Object-affected harmful factors
If a rigid cover is used to protect components, then protection from foreign matter is improved, but ease of operation deteriorates
Solution Approach 1:
The patent specifically uses a flexible elastic cover instead of a rigid structure. This flexible material allows the cover to deform elastically during the rotational operation of the rotation link, maintaining both protection and operational ease.
3Object-affected harmful factors
If the cover member is tightly fitted to protect components, then protection from foreign matter is improved, but adaptability to seat movement deteriorates
Solution Approach 1:
The elastic material of the cover member allows it to stretch and deform as the seat moves vertically and the rotation link rotates. This flexibility maintains tight coverage for protection while adapting to various positions and movements of the adjustment mechanism.
Solution Approach 2:
The cover member's dynamic elastic properties enable it to adapt continuously to the changing geometry of the adjustment unit during operation, maintaining both protective coverage and movement adaptability.

AI summary
To provide a conveyance seat device capable of appropriately protecting components of a seat height adjustment unit from the outside. A conveyance seat S includes a saddle-type seat on which an occupant sits to straddle and a seat height adjustment unit which is attached below the seat and is able to adjust a height position of the seat. The seat height adjustment unit includes a rotation link 60 which rotates together with the seat with respect to a chassis to adjust a height position of the seat, an upper link support member 40 that is provided between the seat and the rotation link 60 and is used so that an upper end portion of the rotation link 60 is attached thereto, a lower link support member 50 that is provided between the rotation link 60 and the chassis and is used so that a lower end portion of the rotation link 60 is attached thereto, and a flexible cover member 90 that covers the rotation link 60 from the outside in a front to back direction of the seat and a width direction of the seat.
