Child Seat Adjustment Structure With Cable-Operated Tilt Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat tilt angle adjustment structures are complex, leading to difficulties in assembly and increased costs, and they lack flexibility to adjust the tilt angle when the seat is facing in any direction.
Innovation Solution
A seat adjustment structure that allows the seat to slide and rotate relative to the base, featuring engaging members, a locking assembly, an operating member, and a cable system that enables easy adjustment of the seat's tilt angle regardless of its orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a normal seat tilt angle adjustment structure is used, then the seat can be adjusted to upright or lying state, but the design becomes complicated leading to difficult assembling and increased cost
Solution Approach 1:
The adjustment structure is divided into independent modular components: engaging members with engaging holes, a locking assembly with locking pin, and an operating member. These segmented components can be assembled separately and connected through simple interfaces, reducing overall assembly difficulty while maintaining adjustment functionality.
Solution Approach 2:
A cable is introduced as an intermediary element to transmit the operating force from the operating member to the locking assembly. This cable-mediated transmission simplifies the direct mechanical connection requirements, allowing for more flexible and easier assembly of the adjustment mechanism.
2Adaptability or versatility
If the seat needs rotation about vertical axis for fore and aft direction adjustment, then the seat can face forward, rearward or sideways, but the tilt angle adjustment structure needs more flexible operation mode
Solution Approach 1:
The locking assembly is designed with a universal engagement mechanism that can lock the seat at multiple orientations (forward, rearward, sideways) while maintaining the same tilt adjustment operation. The engaging members and locking pin configuration allows the same adjustment mechanism to function across different seat orientations, providing both versatility and operational simplicity.
Solution Approach 2:
The adjustment structure incorporates dynamic elements that allow smooth transition between different seat orientations and tilt angles. The cable-operated locking mechanism enables continuous adjustment motion rather than rigid stepped changes, making the system adaptable to various orientations while maintaining ease of operation.

AI summary
A seat adjustment structure for adjusting a relative position between a seat and a base carrying the seat is provided. The seat adjustment structure is capable of sliding with respect to the base along a first direction and includes: one pair of engaging members, fixed to one of the base and the seat with respect to the first direction; a locking assembly, fixed to the other of the base and the seat, capable of being locked to or unlocked from the engaging member; an operating member, mounted on the seat or the base, capable of moving with respect to the seat along a second direction substantially perpendicular to the first direction; and a cable, connecting the operating member and the locking assembly, and being arranged to transmit a movement of the operating member to the locking assembly, thereby causing the locking assembly to be locked or unlocked with respect to the engaging members, such that the base is locked or unlocked with respect to the seat.
