Vehicle Rear Structure Child Seat Anchor Carpet Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle rear structures face challenges in securely attaching child seats while preventing the rear floor carpet from sinking, which can lead to uneven carpeting and potential interference with child seat anchors, especially when the seat back is reclined or erected.
Innovation Solution
A child seat attachment member with a panel-shaped base portion fixed to the floor panel, featuring first raised portions for aligning child seat anchors with engagement members and a second raised portion to maintain carpet height, preventing sinking and ensuring smooth carpet placement without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a child seat attachment member is installed on the floor panel near the back side of the rear seat, then child seat fixation is achieved, but the rear floor carpet tends to sink in and droop near the attachment member
Solution Approach 1:
The patent introduces a third dimension (vertical height) by providing raised portions on the child seat attachment member. The base portion is raised from the floor panel, and the anchor portions are raised from the base portion, creating a stepped structure that prevents carpet sinking while maintaining child seat fixation functionality.
2Shape
If the rear floor carpet is connected to the backrest of the rear seat to prevent sinking, then carpet flatness is improved, but the structure becomes more complex and may interfere with child seat anchors
Solution Approach 1:
The patent extracts the carpet support function from the seat back structure and relocates it to the child seat attachment member on the floor panel. The raised portions on the attachment member independently support the carpet, eliminating the need to connect the carpet to the backrest and simplifying the overall structure.
3Volume of moving object
If the rear floor is elevated from the passenger compartment floor, then trunk room space is optimized, but the rear floor carpet has a tendency to droop and sink in
Solution Approach 1:
The patent applies local quality by creating raised portions only in specific locations where the child seat attachment member is installed. The base portion is raised from the floor panel, and anchor portions are raised from the base portion, providing localized support to prevent carpet sinking only in the necessary areas while maintaining the overall elevated trunk floor design.

AI summary
A vehicle rear structure is provided to which a child seat is attached and that furthermore prevents a rear floor carpet from sinking in. The vehicle rear structure 100 includes a child seat attachment member 112 placed on a floor panel near a back side of a rear seat, and a rear floor carpet 110 covering the child seat attachment member. The child seat attachment member includes a panel-shaped base portion 116 bent to be fixed to a step portion of the floor panel, and child seat anchors 118a and 118b that are respectively to be coupled to child seat engagement members 108a and 108b extending from the child seat on the rear seat. The base portion 116 includes first raised portions 124a and 124b that are respectively formed at positions corresponding to the child seat anchors, and a second raised portion 126 formed between the first raised portions, the second raised portion 126 raising the height of the carpet to substantially the same height as the height of the carpet on the child seat anchors.
