Pivot Arm Linkage for Rider Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders on vehicles like motorcycles and all-terrain vehicles face fatigue due to the need to hold on to the driver with both hands, increasing the risk of falling off, as existing securement solutions do not effectively free up the passenger's hands while ensuring safety.
Innovation Solution
A securement apparatus comprising a pair of harnesses connected by a linkage assembly that adjusts to vary the separation distance between riders, allowing for relative movement and securing them together, thereby enabling the rear rider to use their hands freely without compromising safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the passenger rider holds on to the driver with both hands, then the rider can maintain stability on the vehicle, but the rider's hands are not freed and fatigue increases over time
Solution Approach 1:
The securement apparatus divides the restraint function into separate components: a driver wearability component with first attachment structure, and a passenger wearability component with second attachment structure. The linkage assembly connects these components through pivotable arms rather than direct hand-holding, segmenting the force transmission path and allowing hands-free operation while maintaining stability.
Solution Approach 2:
The linkage assembly acts as an intermediary mechanism between the driver and passenger. Instead of the passenger directly holding the driver, the pivotable arms and connection points serve as intermediaries that transmit stabilizing forces while allowing the passenger's hands to be freed from direct contact with the driver.
2Strength
If a rigid connection is used between riders, then structural strength is maximized, but the ability to accommodate relative movement between riders is reduced
Solution Approach 1:
The linkage assembly employs pivotable arms that can rotate at connection points, transforming a static rigid connection into a dynamic articulated structure. This allows the connection to maintain strength through structural integrity while adapting to relative movements between the driver and passenger during vehicle operation.
Solution Approach 2:
The pivotable arms are configured to nest or fold together when not in use, allowing compact storage while maintaining full functionality during operation. The arms can be positioned in different configurations to accommodate various rider positions and vehicle movements while preserving connection strength.

Function Achieved in This Case
The apparatus enhances rider safety by allowing hands-free operation for the rear rider, accommodating different vehicle positions and movements, while maintaining connection between riders to prevent falls.
Implementation Method 1
a pivot arm comprising a first end pivotably mounted to the second end of the first arm and a second end

AI summary
A securement apparatus for connecting a plurality of riders together on a vehicle is provided. The securement apparatus includes a pair of harnesses having a first harness coupled to a first rider and a second harness coupled to a second rider, and a linkage assembly connecting the first and second harnesses together, the linkage assembly having a first arm with a first end coupled to the first harness and a second end, a pivot arm with a first end pivotably mounted to the second end of the first arm and a second end, and a third arm with a first end pivotably mounted to the second end of the pivot arm and a second end coupled to the second harness. The pivot arm is designed to pivotably adjust relative to the first and third arms to adjust the separation distance between the first and second harnesses.
