Child Carrier Headrest Locking for Belt-Free In-Car Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child restraint systems face difficulties in adjusting the reclined angle of the base portion and the position of the headrest relative to the seat body, requiring disconnection of vehicle anchors or belts for access, making the adjustment process complicated and obstructed.
Innovation Solution
A child restraint carrier with a locking mechanism that includes a driving component, first and second engaging modules, and a recovering component, allowing easy adjustment of the headrest relative to the seat body without disconnection of vehicle anchors or belts, utilizing an inclined protrusion to disengage the second engaging module from the first engaging module for movement, and a rivet to connect the headrest, driving component, and second engaging module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional child restraint system is secured on a vehicle by a lower anchor or vehicle belt, then the base portion can be adjusted to a proper reclined angle, but access to the recline actuator is obstructed by the vehicle seat back, requiring disconnection of the anchor or belt for adjustment
Solution Approach 1:
The patent introduces a notch structure that creates a new spatial dimension for accessing the recline actuator. The notch is formed on the top portion of the base body, allowing the actuator to be accessed from the top direction rather than from the rear, thereby avoiding obstruction by the vehicle seat back while maintaining the connection to lower anchors or vehicle belts
2Ease of operation
If the conventional child restraint system is secured on a vehicle, then the system provides safety protection, but the position adjustment of the headrest relative to the seat body is complicated
Solution Approach 1:
The patent implements a self-service adjustment mechanism where the headrest is equipped with a driving component that can be manually operated by the user. This driving component directly engages with the seat body structure to enable height adjustment, eliminating the need for complex external adjustment mechanisms or professional installation assistance
3Reliability
If the locking mechanism uses multiple engaging modules for secure locking, then the reliability of the locking system is improved, but the structure becomes more complex
Solution Approach 1:
The patent divides the locking mechanism into multiple independent engaging modules, each with its own engaging component. The first engaging module and second engaging module are separately configured but work together through the driving component, providing redundant locking points that enhance reliability while maintaining a relatively simple overall structure through modular design

AI summary
A child restraint carrier includes a seat body, a headrest and a locking mechanism. The headrest is movably installed on the seat body. The locking mechanism is for allowing or restraining a movement of the headrest relative to the seat body. A position of the headrest relative to the seat body can be adjusted easily by the locking mechanism to fit a child. Therefore, the present invention has an advantage of easy adjustment.
