Rear-Facing Child Seat Extension Locking for Anti-Rebound Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats face challenges in providing suitable support to prevent undesirable rotation during vehicle collisions, especially in vehicles with varying seat shapes and sizes.
Innovation Solution
The child safety seat incorporates an extension member and an anti-rebound part that can be adjusted and locked to provide enhanced stability and prevent rotation, ensuring better safety and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a fixed extension panel is used to increase leg room, then the leg room is increased, but the ability to prevent rotation varies with different vehicle seat configurations
Solution Approach 1:
The extension panel is made adjustable through a locking mechanism that allows it to be positioned at multiple locations along the seat shell. This dynamic adjustment capability enables the panel to adapt to different vehicle seat configurations while maintaining adequate leg room for the child.
Solution Approach 2:
The extension panel is divided into multiple discrete positions along the seat shell, allowing selective engagement at different locations. This segmentation enables adaptation to various vehicle seat shapes and sizes by choosing the appropriate engagement position.
2Adaptability or versatility
If the extension panel is made adjustable to fit different vehicles, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The extension panel incorporates a self-locking mechanism that automatically secures the panel at selected positions without requiring additional fastening steps. The parent simply needs to push the panel to the desired location, and the locking mechanism engages automatically, reducing operational complexity.
Solution Approach 2:
A locking mechanism serves as an intermediary between the extension panel and the seat shell, providing a simple interface that enables adjustment while maintaining structural integrity. This intermediary component simplifies the overall adjustment process.

AI summary
A child safety seat includes a seat shell for receiving a child, an extension member, an extension locking mechanism operable to lock the extension member with respect to the seat shell, and an anti-rebound part. The anti-rebound part can be installed on the extension member or the seat shell. The child safety seat is installable on a vehicle seat in a rear facing position with the anti-rebound part extending at an angle above the extension member and adjacent to a seatback of the vehicle seat.
