Motorcycle Seat Assembly With Pivoting Width Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle seat assemblies are inflexible and costly, requiring multiple seats for different riding styles and lacking the ability to adjust width easily, especially during a ride.
Innovation Solution
An adjustable seat assembly with pivoting sections that can be widened or narrowed using a locking device and fastening means, allowing for multiple positions without the need for additional seats, and can be adjusted manually or automatically using an electric motor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple seats of different widths are provided to accommodate different riding styles, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The seat assembly is designed with pivoting sections that can rotate relative to each other, transforming the static seat into a dynamic structure. The first and second pivoting sections can be adjusted to different angles using the adjustment device, allowing the seat width to change from a narrow configuration (for dynamic riding) to a wider configuration (for comfortable long-distance riding), eliminating the need for multiple separate seats
Solution Approach 2:
The single seat assembly is designed to perform multiple functions by accommodating different riding styles through width adjustment. The seat can serve both as a narrow sport-oriented seat and a wide comfort-oriented seat, making one universal seat replacement for what would traditionally require multiple specialized seats
2Adaptability or versatility
If additional seats are provided for different riding styles, then adaptability is improved, but loss of time increases due to replacement requirements
Solution Approach 1:
The dynamic pivoting mechanism allows the seat width to be adjusted in real-time during a ride by operating the adjustment device, eliminating the need to stop and physically replace seats. The adjustment can be made quickly by rotating the pivoting sections to the desired angle and locking them in place
3Device complexity
If the seat width is fixed, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The seat assembly is divided into multiple independent pivoting sections (first pivoting section and second pivoting section) that can be adjusted independently. Each section can be rotated to different angles and locked in position, providing discrete width adjustments while maintaining a relatively simple overall structure based on modular segments
Solution Approach 2:
The seat width is adjusted by changing the angular parameter of the pivoting sections. The adjustment device modifies the rotation angle of each pivoting section, thereby changing the overall width parameter of the seat assembly to suit different riding conditions

AI summary
Described is an adjustable seat assembly (16) for a motorcycle (10), which has a seat pan (17) and an adjustment mechanism (28) The seat pan (17) comprises a base portion (18) and two pivoting portions (20, 22) that are pivotally connected to the base portion (18) and that lie adjacently to one another, seen from the longitudinal direction of the seat assembly (16), on the base portion (18). The base portion (18) has a fastening portion (30) for fastening the seat assembly (16) on the motorcycle (10). The adjustment mechanism (28) is designed to pivot each of the two pivoting portions (20, 22) in relation to the base portion (18). Also described is a motorcycle (10).
