Child Restraint Fastener Mechanism with Automatic Latching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing child restraint systems on vehicle seats are often cumbersome and fail to achieve a snug and secure installation, making it difficult to ensure safety for children.
Innovation Solution
A safety belt assembling device with a fastener mechanism that includes a latching hook, locking rod, and releasing actuator, allowing for easy and secure attachment of the child restraint system to the vehicle seat, utilizing a panel to press the safety belt into a sunken structure and engaging it with a fastener mechanism to prevent rotation, with a two-stage operation and automatic recovering function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional installation methods are used, then the child restraint system can be installed on the vehicle seat, but the installation is difficult to achieve snug and secure
Solution Approach 1:
The patent replaces complex manual mechanical installation with an automated fastening system. The panel automatically presses the safety belt into the sunken structure, and the latching hook automatically engages with the locking rod, substituting manual manipulation with automated mechanical action to achieve secure installation without requiring user skill or effort.
Solution Approach 2:
The fastening system is self-actuating through the interaction between the panel, safety belt, sunken structure, and latching mechanism. Once the panel presses the belt into position, the latching hook automatically catches the locking rod without requiring additional user input, making the system self-service and eliminating the need for complex manual installation procedures.
2Reliability
If a secure fastening mechanism is used, then the child restraint system is stably constrained, but the installation requires significant effort
Solution Approach 1:
The latching hook is designed to dynamically engage with the locking rod through automatic motion rather than requiring static force application. The panel's pressing action creates dynamic movement that guides the latching hook into the locked position, converting user effort into automatic engagement that secures the restraint without requiring the user to apply significant force.
Solution Approach 2:
The safety belt acts as an intermediary element between the panel and the sunken structure. The panel presses the safety belt, which then engages with the sunken structure and triggers the latching mechanism. This intermediary action allows the system to achieve stable constraint through distributed force rather than requiring concentrated user effort.
3Adaptability or versatility
If the panel is rotatably disposed to press the safety belt, then the assembly is flexible, but the panel may rotate unintentionally
Solution Approach 1:
The latching hook extracts the rotational freedom from the panel by selectively engaging with the locking rod. While the panel remains rotatably disposed for flexibility during installation, the latching mechanism removes the ability to rotate once fastened, separating the flexibility needed during assembly from the stability needed during use.
Solution Approach 2:
The fastening system is segmented into distinct functional components: the rotatable panel for positioning, the safety belt for transmission, the sunken structure for guidance, and the latching hook for stabilization. This segmentation allows each component to perform its specific function - the panel provides flexibility while the latching mechanism provides stability - without compromising the other.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and secure installation of child restraint systems on vehicle seats with minimal effort, ensuring stability and safety by using a latching hook and releasing actuator mechanism that automatically recovers to locked positions.
Implementation Method 1
The fastener mechanism further includes a first recovering component disposed between the latching hook and the panel, and utilized to engage the latching hook with the locking rod
Implementation Method 2
The fastener mechanism further includes a second recovering component disposed between the releasing actuator and the panel, and utilized to press the releasing actuator from the protruding position to the flush position

AI summary
A safety belt assembling device is designed to assemble a child restraint system with a vehicle seat. The safety belt assembling device includes a child restraint having a sunken structure, a panel and a fastener mechanism. The child restraint is connected with the child restraint system. The panel is rotatably disposed on the child restraint and adapted to press a safety belt of the vehicle seat inside the sunken structure. The fastener mechanism includes a locking rod, at least one latching hook and a releasing actuator. The locking rod is disposed inside the sunken structure. The latching hook is rotatably disposed on the panel and utilized to detachably catch on the locking rod. The releasing actuator is rotatably disposed on the panel and connected with the latching hook. The releasing actuator is rotated from a flush position to a protruding position to disengage the latching hook from the locking rod.
