Pivotable Safety Belt Bracket for One-Hand Driver Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicle drivers operating heavy load vehicles often underestimate the risk of capsizing and fail to use safety belts due to perceived inconvenience, leading to increased accident hazards, as the existing safety systems are not adequately accepted or utilized.
Innovation Solution
A pivotable safety belt bracket that can be easily fastened with a single hand movement, designed to be out of the way during entry and exit, with a spring-assisted releasing position, a handle for ergonomic operation, a lock latch for secure fastening, a red-colored belt for visibility, illumination for external monitoring, and an immobilizer system to ensure proper use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the safety belt bracket is made pivotable to enable easy fastening with single hand movement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The bracket is designed to be pivotable between a storing position and a fastening position, transforming a static structure into a dynamic one. This allows the bracket to adapt its position for different operational phases (entry/exit vs. fastening), improving ease of operation while maintaining reasonable complexity through controlled movement rather than multiple separate components
Solution Approach 2:
The safety belt system is divided into separate functional components: the pivotable bracket, the safety belt itself, the locking mechanism, and the releasing mechanism. This segmentation allows each component to be optimized independently, with the bracket handling positioning and the locking mechanism handling securation, thereby improving overall operability without excessive complexity
2Area of moving object
If the bracket is positioned close to the driver's seat to optimize space utilization, then the area of moving object is improved, but the ease of operation deteriorates due to uncomfortable constriction in shoulder region
Solution Approach 1:
The pivotable bracket dynamically adjusts its position based on operational needs. During entry and exit, it remains in the storing position close to the seat, optimizing space utilization. During fastening, it pivots to the fastening position, providing adequate clearance for the driver's shoulder and hand movements, thus resolving the contradiction between space efficiency and operational comfort
Solution Approach 2:
The bracket is pre-positioned in the storing position during vehicle operation, keeping it out of the driver's way and optimizing space. When fastening is needed, the bracket is preliminarily moved to the fastening position before the driver attempts to fasten the belt, ensuring adequate space for comfortable operation without requiring the driver to maneuver around obstructions
3Measurement precision
If the safety belt is made visible with red color and illumination, then the measurement precision of safety belt usage is improved, but the device complexity increases
Solution Approach 1:
The safety belt is colored red instead of the conventional black or gray, providing immediate visual differentiation and clear indication of its presence and usage state. This simple color change significantly improves visibility and monitoring precision without adding mechanical or electronic complexity
Solution Approach 2:
The bracket includes an illumination device that can be activated to enhance visibility of the safety belt and its fastening state. This optical enhancement allows for easy visual verification of proper usage, particularly in low-light conditions, while maintaining relatively simple device architecture through the use of basic illumination components rather than complex detection systems
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
Enhances driver acceptance and utilization of safety systems by simplifying belt fastening, improving visibility and external monitoring, and ensuring the safety belt is always used during vehicle operation, thereby reducing accident risks and fatalities.
Implementation Method 1
In order to facilitate entry and exit, it is advantageous for the at least one bracket in the releasing position to be held by at least one spring.

AI summary
A motor vehicle (1) has a driver's seat (8) which is assigned a safety belt (20) for a driver. The safety belt (20) here is held on a pivotable bracket (13). This bracket (13) is pivotable between a releasing position, which permits entry, and a restraining position, which protects the driver. The bracket (13) here is disposed in such a manner that said bracket (13) in the releasing position holds the safety belt (20) in a position in which the latter impedes the driver. In order to avoid any impediment of the driver in the restraining position of the bracket (13), the bracket (13) above the driver's seat is elbowed away from the latter.
