Vehicle Restraint System with Segmented Straps for Side-Facing Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seat restraint systems in emergency vehicles, such as ambulances, are ineffective in side-facing seats, as they do not provide sufficient mobility for medical professionals to administer care while in motion and lack data on performance in such configurations.
Innovation Solution
A restraint system comprising upwardly-extending shoulder strap portions, horizontally-extending positioning strap portions, and lower strap portions, connected to retractors, designed for use in forward-facing, rearward-facing, or side-facing seating, ensuring mobility and effective restraint in emergency vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional seat restraint systems are used in side-facing seats, then the restraint system provides basic restraint function, but the system does not provide sufficient mobility for medical professionals to administer care while in motion
Solution Approach 1:
The restraint system is divided into multiple independent strap portions (shoulder straps, positioning straps, lower straps) that can be independently adjusted and positioned. This segmentation allows the medical professional to configure the restraint system to provide both mobility for administering care and reliable restraint when needed, resolving the contradiction between ease of operation and reliability in side-facing seats
2Adaptability or versatility
If conventional restraints are used, then the system is simple in structure, but the system is only partially effective in side-facing seats with insufficient mobility
Solution Approach 1:
The restraint system is designed with multiple strap portions that can be configured for different seating orientations (forward-facing, rearward-facing, side-facing). The shoulder straps, positioning straps, and lower straps work together in various configurations, making the system universally applicable to different seat types while maintaining manageable complexity through standardized components
Data Source
AI summary
A vehicle passenger restraint system is disclosed. The restraint system has a pair of vertically extending shoulder strap portions, horizontally extending positioning strap portions attached to the shoulder strap portions, and horizontally extending lower strap portions spaced vertically below the positioning strap portions. The shoulder strap portions may be contiguous with one another, so as to form one continuously linked shoulder strap portion. The shoulder strap portions and positioning strap portions may be connected to retractors. The restraint system is particularly suitable for use in emergency vehicles such as ambulances, and may be used in forward-facing, rearward-facing or side-facing seating.
