Solution Overview
Problem
Existing vehicle seats with rockable portions protrude from the seat surface, causing discomfort and a conspicuous exterior appearance, which can be exacerbated by increasing the size of the movable portion to enhance rocking motion transmission.
Innovation Solution
A vehicle seat design featuring a recessed portion in the seat surface to accommodate a rockable movable portion, with a through hole for a drive mechanism, where the movable portion extends to the periphery of the through hole and is shaped to fit seamlessly within the seat surface, using a flexible and friction-reducing material to ensure smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the movable portion is enlarged to effectively transmit rocking motion to the seated person, then the rocking motion transmission is improved, but the exterior appearance becomes conspicuous and uncomfortable
Solution Approach 1:
The movable portion is nested within a recessed portion formed in the seat cushion, allowing the rocking mechanism to be concealed within the seat surface while still providing effective rocking motion transmission to the seated person
2Ease of operation
If the movable portion is enlarged to transmit rocking motion, then the rocking effectiveness is improved, but the movable portion protrudes from the seat surface causing discomfort
Solution Approach 1:
The movable portion is nested within a recessed portion formed in the seat cushion, allowing the rocking mechanism to be concealed within the seat surface while still providing effective rocking motion transmission to the seated person

AI summary
Provided is a vehicle seat with a structure enabling a rockable moving piece to be disposed in a seat face in a well-fitting manner. A vehicle seat in which a rocking means having a drive mechanism and a moving piece for conveying rocking movement of the drive mechanism to a seated person is disposed in a through hole obtained by hollowing out a portion of a seat face of a seat cushion, wherein: a recess which is recessed in the thickness direction so as to surround the through hole is disposed in the seat face of the seat cushion; and the moving piece is shaped so that the bottom surface side follows the recess.
