Child Seat Side Impact Block Locking for Space-Saving Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats with side impact protection devices often have one side impact protection device that is not effective when the seat is positioned close to a car door, leading to unnecessary space occupation and reduced effectiveness.
Innovation Solution
A limiting device is introduced to prevent the side impact protection block from automatically unfolding when not needed, comprising a mounting portion and a restricting member that can move between a locked and released position to control the unfolding of the side impact protection block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the side impact protection device is provided on both sides of the seat for versatility, then the safety coverage is improved, but the space occupation increases and the device complexity increases
Solution Approach 1:
The side impact protection device is designed to be dynamically adjustable between folded and unfolded positions. The limiting device allows the side impact protection device to be locked in the folded position when not needed, and can be released to unfold when safety is required, making the system adaptive to different operating conditions
Solution Approach 2:
The side impact protection device is segmented into independent controllable units on each side of the seat. The limiting device can independently control the left and right side impact protection devices, allowing selective deployment based on specific safety needs rather than requiring both sides to be constantly deployed
2Speed
If the side impact protection device is automatically unfolded when the child is seated, then the safety response speed is improved, but the space occupation increases when not needed
Solution Approach 1:
The system dynamically adjusts the state of the side impact protection device based on real-time conditions. The limiting device enables automatic unfolding when safety is needed while maintaining the folded state when not needed, optimizing the balance between rapid safety response and space efficiency
Solution Approach 2:
The side impact protection device with automatic unfolding mechanism can self-activate when safety conditions are met, while the limiting device ensures it returns to or remains in the folded state when not needed, making the system self-regulating
3Volume of moving object
If the side impact protection device is locked in the folded position, then the space occupation is reduced, but the ease of operation decreases
Solution Approach 1:
The limiting device acts as an intermediary control mechanism that manages the locked and unlocked states of the side impact protection device. It provides a controlled interface that simplifies the operation of unfolding the device while maintaining the compact folded state when not needed

AI summary
According to the application, a limiting device is used for limiting a pivoting of a side impact protection block in respect to a child safety seat. The limiting device includes: a mounting portion, located on a seat body of the child safety seat and arranged close to the side impact protection block; and a restricting member, has a free end and is arranged on the mounting portion, such that the restricting member is movable between a locked and released position. In the locked position, the free end of the restricting member abuts against the side impact protection block to prevent the side impact protection block from moving in an unfolding direction, and in the released position, the free end of the restricting member is away from the side impact protection block to allow side impact protection block to move in the unfolding direction.
