Motorcycle Seat Backrest Heating With Waterproof Harness Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-wheeled motor vehicle seat devices with movable backrests lack heating functionality and are prone to water ingress, which can soak the cushion material, especially during rainy conditions.
Innovation Solution
Incorporating a heater into the movable backrest with a harness connected to a power supply, and utilizing a harness guide tube and waterproof guide frame to ensure the heater remains functional and prevent water from entering the gap between the seat main body and backrest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heater is incorporated into the movable backrest, then the driver can be warmed up and enjoy a pleasant and comfortable ride when the temperature is low, but the harness connected to the heater may become tangled or damaged due to the backrest movement
Solution Approach 1:
A harness guide tube is introduced as an intermediary component between the movable backrest and the fixed seat main body. The guide tube moves together with the backrest while guiding the harness through it, preventing the harness from becoming tangled or damaged during backrest movement. The guide tube extends through the seat main body and is retained at the rear end, creating a protected pathway for the electrical harness.
2Ease of operation
If the backrest moves in the fore-and-aft direction on the seat main body, then the seat position for the driver can be adjusted, but water such as rain water may flow into a gap between the seat main body and the backrest and soak the cushion material
Solution Approach 1:
A waterproof guide frame is introduced as a mediating structure between the movable backrest and the seat main body. The guide frame includes guide parts that extend within the opening of the seat main body while straddling the skin material and seat bottom, creating a waterproof barrier. The guide parts are tubular and prevent water from flowing into the gap between the seat main body and backrest, while still allowing the backrest to move fore-and-aft for position adjustment.
3Ease of manufacture
If the harness is passed through the interior of the seat main body, then the heater can be connected to the power supply, but the harness may interfere with the vehicle body or become exposed between the backrest and seat main body
Solution Approach 1:
The harness guide tube serves as a protective intermediary that channels the harness through the interior of the seat main body. The guide tube is received by a recess portion in the lock cover and is retained at the rear end, ensuring the harness remains protected and does not become exposed between the backrest and seat main body. This arrangement prevents the harness from interfering with the vehicle body while maintaining ease of heater installation.
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 solution provides a heated backrest that remains operational during movement, while the waterproof guide frame effectively prevents water from reaching the cushion material, enhancing both comfort and durability.

AI summary
A two-wheeled motor vehicle seat device with a backrest provided on a seat main body so as to be movable in a fore-and-aft direction is provided in which the backrest is provided on the seat main body mounted on a vehicle body so that the backrest can move in a fore-and-aft direction thereof, a heater is incorporated into the backrest, and a harness connected to the heater is passed through an interior of the seat main body and connected to a power supply. This enables the heater to be incorporated into the backrest to heat the backrest without interfering with the fore-and-aft movement of the backrest.
