Adjustable Child Seat Assembly with Joint-Based Backrest Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child and baby transportation seats in bicycle trailers lack versatility, as they are not suitable for adjusting to accommodate both lying and sitting positions, and do not cater to the needs of transporting babies effectively.
Innovation Solution
A seat arrangement with adjustable support surfaces connected via joints that allow for angular positioning, enabling the configuration of seats and backrests to accommodate different angles and positions, including reclined and upright arrangements, and the ability to adjust length to fit various sizes and spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed rigid seats are used in bicycle trailers, then structural stability is improved, but adaptability to different age groups and positions is worsened
Solution Approach 1:
The support structure incorporates joints that enable dynamic adjustment of the backrest angle, allowing the seat to adapt between upright sitting positions for older children and reclining positions for babies, while maintaining structural stability through lockable joint mechanisms
2Adaptability or versatility
If adjustable backrest mechanisms are added to child seats, then versatility for different positions is improved, but structural simplicity and ease of manufacture are worsened
Solution Approach 1:
The support structure is divided into separate components (first support part for the seat base, second support part for the backrest, and connecting joints), allowing each part to be manufactured independently using simple processes while enabling angular adjustment through the joint connections
3Reliability
If separate baby carrier and child seat are used, then suitability for specific age groups is improved, but device complexity and number of components are worsened
Solution Approach 1:
The support structure is designed as a universal system that can accommodate both babies and children through adjustable backrest angles. The same seat structure provides reclining positions for babies and upright positions for children, eliminating the need for separate carrier and seat components

AI summary
The invention relates to a seating arrangement for the transport of persons, in particular babies, toddlers and children, in a passenger compartment of a vehicle, in particular a bicycle with a cargo area having a passenger compartment or a multi-functional bicycle trailer, in which at least one fastening element for fastening the seating arrangement (63) is provided, with a first support surface and a second support surface and a support (61) holding these.The seating arrangement according to the invention offers improved functionality in that the support has a first support part holding the first support surface and a second support part holding the second support surface and at least one joint (633) with which an angle between the first support part and the second support part can be adjusted, wherein the first support surface and the second support surface are connected to the support parts in such a way that their angular position (69) to each other corresponds to the angular position of the two support parts to each other.
