Vehicle Seat Headrest Connector Mounting Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs require a separate holder for the second connector, making it difficult to easily mount a headrest with integrated electric components.
Innovation Solution
A vehicle seat design featuring a seatback with a mounting portion and a headrest frame that includes a first connector inserted into the mounting portion, and a second connector connected to the seatback frame, allowing for irreversible engagement and easy mounting of the headrest with electric components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate holder is used to hold the second connector, then the connector can be securely positioned, but the device complexity and mounting difficulty increase
Solution Approach 1:
The holder for the second connector is merged with the seatback frame, forming an integrated structure. The holder is fixed to the seatback frame and simultaneously holds the second connector, eliminating the need for a separate holder component and reducing overall device complexity while maintaining secure connector positioning
Solution Approach 2:
The seatback frame serves multiple functions: it provides structural support for the seatback, holds the second connector through the integrated holder, and facilitates the insertion and connection of the first connector. This multi-functionality reduces the number of separate components needed in the system
2Stability of the object's composition
If a holder is added to hold the second connector, then connector stability is improved, but the ease of manufacture and installation deteriorate
Solution Approach 1:
By combining the holder function with the seatback frame, the manufacturing process is simplified as fewer separate components need to be produced and assembled. The integrated structure requires only one fixation operation during assembly, improving both manufacturing ease and installation simplicity while maintaining connector stability
Solution Approach 2:
The holder is pre-fixed to the seatback frame during manufacturing, so that during final assembly only the insertion of the first connector is needed. This preliminary action of fixing the holder in advance simplifies the final installation process and reduces mounting time
3Reliability
If a separate holder structure is used, then the second connector can be properly positioned, but the mounting time and installation complexity increase
Solution Approach 1:
The integration of the holder with the seatback frame reduces the number of assembly steps to a single insertion motion, significantly reducing mounting time while ensuring reliable connector connection through the pre-positioned holder structure
Solution Approach 2:
The holder is pre-installed and positioned on the seatback frame before the final assembly step. This preliminary positioning ensures that when the first connector is inserted, the connection is immediately established without requiring additional adjustment or positioning steps, reducing overall mounting time

AI summary
A vehicle seat is equipped with a seatback having a mounting portion, a headrest having a headrest frame and an electric component, a first connector, and a second connector. The first connector has an engaging portion engaged with a hole of the headrest frame, a protrusion engaging the second connector, and a first connector terminal electrically connected to a lead wire of the electric component. The second connector has a first engaging piece engaged with a hole of the guide bracket from the outside of the guide bracket, a second engaging piece engaged with the protrusion of the first connector from the outside of the first connector, and a second connector terminal electrically connected to a lead wire wired in the seatback and the first connector terminal. The engagement between the hole of the mounting portion and the first engaging piece of the second connector can be released irreversibly.
