Pivotable Vehicle Seat Belt System in Headrest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seat belt systems in mobile homes are aesthetically unappealing when the living space is used, as the safety belt system is disadvantageously visible when parked.
Innovation Solution
A vehicle seat with a pivotable seat belt system element integrated into the headrest or neck rest, which can be fixed or locked in use or stowed positions, allowing the system to be positioned advantageously for the user and hidden from view when not in use, utilizing a rotary bearing for pivoting and a storage space in the backrest for concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the safety belt system is fixedly positioned above the shoulder area on the vehicle frame, then the seat belt system is always visible, but this creates an aesthetically unappealing appearance when the living space is in use
Solution Approach 1:
The seat belt system is made dynamically positionable through a pivotable headrest mechanism. The headrest can rotate between a forward position (where the seat belt is accessible) and a rearward position (where the seat belt is concealed in the recess). This dynamic positioning resolves the contradiction by allowing the system to adapt its appearance based on usage requirements.
Solution Approach 2:
The seat belt system is nested within the headrest structure, which itself is integrated into the backrest with a recess. When the headrest is positioned rearward, the seat belt system becomes nested within the recess, concealing it from view. This nesting approach allows the seat belt to be both functional and aesthetically hidden when not in use.
2Ease of operation
If the headrest and seat belt system pivot together, then both components can be moved from functional position to stowed position simultaneously, but this requires precise coordination of the pivoting mechanism
Solution Approach 1:
The headrest and seat belt system are merged into a single integrated assembly that pivots together as one unit. This integration eliminates the need for separate pivot mechanisms and coordination systems, as the entire assembly moves simultaneously through a single pivot point, reducing mechanism complexity while maintaining ease of operation.
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 user-friendly and aesthetically pleasing integration of the seat belt system, ensuring it is both functional and concealed when not in use, enhancing safety and appearance in the vehicle's living space.
Implementation Method 1
the headrest and the seat belt system element pivot in the same direction... the headrest and the seat belt system element pivot together, for example in a scissor-like motion
