Vehicle Seat Guide Groove Nesting Support Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats fail to effectively utilize space when tipped up, limiting the efficient use of interior space in vehicles.
Innovation Solution
A vehicle seat design featuring a cushion frame with a guide groove, a hinged seat frame, and a support link that rotates and moves within the guide groove, allowing the support link to be accommodated inside the cushion frame when tipped up, along with a locking mechanism to secure the seat in the tipped-up position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the seat is tipped up to maximize space utilization, then interior space is improved, but the support link protrudes outward and reduces effective space
Solution Approach 1:
The support link is designed to be nested within the cushion frame when the seat is in the tipped-up position. The cushion frame includes a receiving space that accommodates the support link, allowing the support link to be stored inside the cushion frame rather than protruding outward, thereby maximizing interior space utilization.
2Strength
If the support link is made long to ensure structural stability, then strength is improved, but space utilization deteriorates when tipped up
Solution Approach 1:
The cushion frame is designed with a receiving space that can accommodate the support link in its entirety when the seat is tipped up. This allows the support link to maintain its necessary length for structural stability while being fully contained within the cushion frame during storage, optimizing both strength and space utilization.
Solution Approach 2:
The support link is designed with a bent configuration rather than a straight line, allowing it to fit within the three-dimensional receiving space of the cushion frame. This dimensional arrangement enables the support link to maintain sufficient length for structural integrity while accommodating within the available space when tipped up.
3Ease of operation
If the support link is allowed to move freely during rotation, then ease of operation is improved, but positioning precision deteriorates
Solution Approach 1:
A guide groove is provided in the cushion frame that guides the movement of the support link during rotation. This intermediary structure ensures that the support link follows a predetermined path, achieving both smooth rotation and accurate positioning in the tipped-up state without requiring complex locking mechanisms.

AI summary
Disclosed is a vehicle seat including a cushion frame having a seat cushion and having a guide groove formed in an end thereof, the guide groove being indented and formed to extend in a longitudinal direction of the cushion frame, a seat frame coupled to the cushion frame through a hinge method so as to allow the cushion frame to be rotatable, and a support link having one end coupled to the seat frame through a hinge method so as to be rotatable and the other end coupled to the guide groove formed in the cushion frame, wherein the other end is movable in the guide groove when the one end is rotated.
