Headrest Cover Attachment Using Inserted Plate Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automobile seat headrests require an outer cover to hide the end edge of the cover, increasing the number of components and potentially compromising appearance quality.
Innovation Solution
A headrest design that integrates a strip-shaped plate member into the insert member's groove, eliminating the need for an outer cover by attaching the cover directly to the insert member, and manufacturing the headrest through integral foam molding to form the outer shape, pad body, and cover simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an outer cover is added to hide the end edge of the cover, then appearance quality is improved, but the number of components increases
Solution Approach 1:
The invention extracts and eliminates the outer cover component by redesigning the attachment mechanism. The cover is directly attached to the insert member using a plate member and locking structure, making the outer cover redundant for both functional and aesthetic purposes.
Solution Approach 2:
The invention merges the functions of the outer cover into the main cover assembly by integrating the plate member attachment system. The cover and insert member are directly combined through the locking mechanism, eliminating the need for a separate outer cover component.
2Device complexity
If the cover is directly attached to the insert member without an outer cover, then the number of components is reduced, but appearance quality may be compromised
Solution Approach 1:
The plate member serves as an intermediary element that enables direct attachment between the cover and insert member while maintaining aesthetic appearance. The plate member is designed to be visually acceptable and structurally functional, replacing the need for an outer cover.
Solution Approach 2:
The invention applies local quality by designing the plate member with specific aesthetic and functional properties at the attachment location. The plate member is configured to provide both structural locking and visual acceptability at the critical end edge area without requiring a full outer cover.

AI summary
A headrest includes an insert member covering a gate-shaped stay other than both legs of the gate-shaped stay, a pad body covering the insert member other than a lower surface of the insert member, a cover having a bag-shape, covering the pad body, and forming an outer shape of a headrest main body, and a strip-shaped plate member attached to an end edge of the cover between the legs in a state where the cover covers the insert member and the legs protrude outward through a cover opening of the cover. The lower surface of the insert member is provided with an insert opening extending in a headrest width direction and disposed between the legs, and the cover is attached to the insert member in a state where the plate member is inserted into the insert opening with the end edge of the cover.
