Movable Seat Harness Buckles for Multi-Occupant Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing restraint systems for vehicle seats are not configurable to accommodate varying numbers and sizes of occupants effectively, lacking the ability to seamlessly adjust to different passenger configurations.
Innovation Solution
A configurable restraint system featuring multiple engagement members and harnesses that can be moved between positions to accommodate one or more occupants, utilizing tongue and buckle mechanisms, and flexible members to ensure secure restraint of occupants of different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a restraint system is designed for a fixed number of occupants, then the restraint mechanism is simple, but it cannot accommodate varying numbers and sizes of occupants
Solution Approach 1:
The restraint system employs movable engagement members that can be repositioned along the seat to accommodate different occupant configurations. The engagement members can be moved between stored and operative positions, and between different engagement positions, allowing the system to dynamically adapt to varying numbers and sizes of occupants rather than being fixed in a single configuration
Solution Approach 2:
The restraint system is designed with multiple engagement members and harnesses that can serve different functions depending on configuration. The same engagement members can restrain different numbers of occupants (one, two, or three) by being positioned at different locations along the seat, making the system universal for various seating arrangements without requiring separate restraint systems for each configuration
2Adaptability or versatility
If multiple engagement members are added to accommodate more occupants, then adaptability improves, but the device complexity increases
Solution Approach 1:
The restraint system combines multiple engagement members and harnesses into a single integrated assembly. The engagement members are movably coupled to the seat structure, allowing them to be repositioned and reconfigured rather than requiring separate, fixed restraint systems for each occupant position. This merging reduces overall system complexity while maintaining the ability to accommodate multiple occupants
3Adaptability or versatility
If engagement members are made movable to adjust positions, then adaptability to different occupant sizes improves, but the ease of operation decreases
Solution Approach 1:
The engagement members are designed with self-contained movable mechanisms that can be easily repositioned by the user without requiring additional tools or complex adjustment procedures. The movable engagement members can be freely moved along the seat to the desired position and then engaged with the harness, allowing users to independently configure the restraint system for their specific needs

AI summary
A configurable restraint system (10-10vi) for a vehicle seat (12, 12′) may comprise a first restraint harness (30-30″) coupled to a first engagement member (32), a second restraint harness (34-34″) coupled to a second engagement member (36), and a third engagement member (50-50″″) configured to be movable between first and second positions relative to the vehicle seat. The first position may be located relative to the vehicle seat so that the first engagement member (32) may releasably engage the third engagement member (50-50″″) to restrain a first occupant of the vehicle seat via the first restraint harness (30-30″). The second position may be located relative to the vehicle seat so that the second engagement member (36) may alternatively releasably engage the third engagement member (50-50″″) to alternatively restrain the first occupant of the vehicle seat via the second restraint harness (34-34″).
