Rotatable Backrest Dual-Mode Vehicle Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats occupy large space, have complex installation processes, and fail to meet safety and comfort requirements due to bulky designs, leading to reduced vehicle trunk volume and uneven market quality.
Innovation Solution
A dual-mode on-vehicle integrated seat with a rotatable backrest system that converts between adult and child seating modes, featuring a positioning device and rotating fork arm mechanism, adjustable angle, height, and safety restraints, allowing efficient space utilization and enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a split-type on-vehicle child seat product is used, then child safety is improved, but vehicle trunk volume is reduced due to large space occupation
Solution Approach 1:
The on-vehicle integrated seat is designed to serve multiple functions: it can be used as an adult seat in normal driving conditions and transform into a child safety seat when needed. The backrest portion can be rotated to expose different sides (first backrest part for adults, second backrest part for children), allowing one seat structure to replace what would traditionally require separate adult and child seats, thereby preserving trunk volume while maintaining child safety
Solution Approach 2:
The seat incorporates a rotatable backrest mechanism that allows dynamic transformation between different seating modes. The backrest can be rotated about a longitudinal axis to switch between exposing the first backrest part (adult mode) and the second backrest part (child mode), enabling the seat to adapt its configuration based on usage requirements rather than being fixed in a single form
2Reliability
If a split-type on-vehicle child seat product is used, then child safety is improved, but installation reliability is difficult to ensure due to complex installation process
Solution Approach 1:
The patent combines the adult seat and child safety seat functions into a single integrated seat structure. The positioning device and rotating fork arm mechanism work together as a unified system to secure the backrest in the correct position. This integration eliminates the need for separate installation procedures for different seat types, reducing complexity and improving installation reliability by providing a single, standardized installation process
3Reliability
If a bulky child seat product is used, then child safety is improved, but vehicle space utilization is reduced
Solution Approach 1:
The integrated seat design allows the same physical structure to serve as both an adult seat and a child safety seat through rotation. When in child safety mode, the second backrest part is exposed and can be folded back to provide lateral support for the child, eliminating the need for a separate bulky child seat and maximizing vehicle space utilization

AI summary
The disclosure relates to a dual-mode on-vehicle integrated seat, a child safety seat, a rotary switching system, and a vehicle. The dual-mode on-vehicle integrated seat comprises: a seat portion configured to be adapted to be installed inside a vehicle; and a backrest portion having a first backrest part and a second backrest part that are opposite to each other, and configured to be rotatable about a longitudinal axis thereof to provide a first sitting mode and a second sitting mode respectively, wherein in the first sitting mode, the backrest portion is rotated so that the first backrest part is exposed to form, together with the seat portion, a seat for adults to sit on, and in the second sitting mode, the backrest portion is rotated so that the second backrest part is exposed to form, by itself or together with the seat portion, a seat for children to sit on. The invention has numerous advantages such as compact structure, high safety reliability, flexible and convenient installation, arrangement and daily use, etc. The application of the invention can significantly improve the comfort, integration degree and safety of the vehicle.
