Pivoting Seat Belt Bracket to Prevent Driver Constriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicle drivers often neglect to use seat belts due to inconvenience and underestimating accident risks, leading to reduced acceptance and increased danger, especially in vehicles prone to tipping over, which can result in fatal accidents.
Innovation Solution
A pivotable seat belt bracket system that automatically engages into a restraint position with a lock latch and optional features like a spring mechanism for easy operation, a handle for ergonomic use, a multi-layer cover for safety, red coloration for visibility, integrated lighting for external monitoring, and an immobilizer system to ensure correct use, all designed to enhance driver acceptance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bracket is positioned close to the driver's seat to optimize space, then space utilization is improved, but the driver experiences constriction in the shoulder area
Solution Approach 1:
The bracket is positioned in the vertical dimension above the driver's seat rather than occupying horizontal space next to the seat. This vertical placement allows optimal utilization of the driver's cab space while preventing constriction in the driver's shoulder area, as the bracket operates in a different spatial dimension.
2Ease of operation
If the safety belt is made highly visible to increase driver awareness, then driver acceptance improves, but the aesthetic appearance of the vehicle interior may be compromised
Solution Approach 1:
The safety belt is colored red to significantly increase its visibility and draw the driver's attention to its presence and importance. This color change enhances driver acceptance and awareness without requiring additional visual elements that would compromise the aesthetic appearance of the vehicle interior.
3Reliability
If the bracket is designed to automatically engage in the restraint position, then safety reliability is improved, but the device complexity increases
Solution Approach 1:
The bracket is designed with self-service capability to automatically engage in the restraint position through a simple pivoting motion. The system uses the driver's natural movement when entering or exiting the vehicle to trigger the automatic engagement, eliminating the need for complex control systems, sensors, or actuators while maintaining high safety reliability.
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 system significantly increases the likelihood of drivers using the seat belt correctly by simplifying engagement, improving visibility, and providing external oversight, thereby enhancing safety and reducing the risk of accidents.

AI summary
A motor vehicle (1) has a driver's seat (8) to which a seat belt (20) for a driver is assigned. The seat belt (20) is held by a pivotable bracket (13). This bracket (13) can pivot between a release position that allows entry and a restraint position that protects the driver. The bracket (13) is arranged such that, in the release position, it holds the seat belt (20) in a position that restricts the driver. To prevent the driver from being restricted in the restraint position of the bracket (13), the bracket (13) is angled away from the driver's seat above it.
