Vehicle Seat Anchor Slit Structure for Child Seat Mountability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats with ISO-FIX compatible anchors face challenges in achieving improved child seat mountability without compromising the seating feel and appearance design when the child seat is demounted, as the extension member provided is insufficient to regulate displacement and maintain aesthetics.
Innovation Solution
A vehicle seat design featuring an anchor storage recess covered with a skin material having an inverse T-shaped slit, where the upper and outer sides of the slit-forming skin materials are sewn to the peripheral part, incorporating a contractile rubber band and guide member to facilitate easy insertion and maintain appearance during demounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an extension member is provided for the slit to expand it during child seat mounting, then child seat mountability is improved, but the appearance design deteriorates when the child seat is demounted
Solution Approach 1:
The slit is designed to dynamically change its state between a closed configuration (when no child seat is mounted) to maintain appearance, and an open configuration (when a child seat is being mounted) to facilitate insertion. The inverse T-like shape with sewn peripheral regions creates a controlled dynamic opening mechanism that expands only in the necessary direction during mounting while remaining aesthetically pleasing when closed.
Solution Approach 2:
The slit is segmented into multiple regions with different functional characteristics: the inverse T-like shape creates distinct opening paths, and the peripheral sewing parts regulate displacement in specific directions. This segmentation allows different portions of the slit to serve different purposes - some regions expand to aid mounting while others maintain structural integrity and appearance when closed.
2Ease of operation
If the slit is expanded to facilitate child seat insertion, then ease of insertion is improved, but displacement regulation of the peripheral region becomes insufficient
Solution Approach 1:
Different regions of the slit have different quality characteristics - the inverse T-like shape provides expanded opening capacity in the insertion direction, while the peripheral sewing parts provide localized displacement regulation. This local quality differentiation allows the slit to simultaneously offer easy insertion through expanded opening and maintain stability through regulated peripheral displacement.

AI summary
The vehicle seat is configured to improve child seat mountability, and to prevent deterioration in appearance design when the child seat is demounted. The vehicle seat includes an anchor storage recess formed in a pad that constitutes the seat for storing an anchor to be engaged with an engagement member attached to a child seat. The anchor storage recess is covered with a skin material having a slit. The slit has an inverse T-like shape.
