Vehicle Seat Shield Attachment Using Front-Insertion Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat designs face challenges in attaching decorative elements like shields to seat cushions where sufficient space is not available in the side portions, making it difficult to secure these components properly.
Innovation Solution
The vehicle seat incorporates a decorative body with first and second locking portions that allow for pivoting and locking mechanisms, enabling attachment even in situations with limited space by restricting movement in the seat width direction and allowing for secure locking to the cushion side frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shield is attached to the seat cushion using conventional methods (inserting fixing legs from left and right directions into through-holes), then the shield can be securely fixed, but sufficient space must be available in the left and right side portions of the seat cushion
Solution Approach 1:
The patent changes the attachment direction from horizontal (left-right insertion) to vertical (front-rear insertion). The fixing leg is inserted from the front side of the seat cushion through a through-hole to engage with the shield, eliminating the need for lateral space. This dimensional change in the insertion direction resolves the space constraint while maintaining secure attachment.
Solution Approach 2:
Instead of inserting the fixing leg from the lateral sides (conventional approach), the patent inverts the insertion direction to approach from the front side. The fixing leg extends from the front surface of the seat cushion, engages with the shield, and is secured from the rear, completely reversing the traditional attachment methodology to solve the space problem.
2Adaptability or versatility
If the shield is attached after the seat is fixed on the floor, then installation flexibility is improved, but conventional attachment methods cannot be used due to insufficient space
Solution Approach 1:
By changing the insertion direction to vertical (front-rear), the patent enables shield attachment even when lateral access is blocked by the floor or other structures. This dimensional change allows installation after seat mounting, providing the desired flexibility while maintaining attachment feasibility in constrained spaces.
3Ease of operation
If the decorative body is allowed to move freely, then ease of installation is improved, but stability and rattling prevention are compromised
Solution Approach 1:
The patent divides the attachment function into two distinct locking portions: a first locking portion that restricts lateral movement and a second locking portion that prevents forward displacement. This segmentation of restraint functions ensures comprehensive stability while maintaining simple installation through the pivoting mechanism.
Solution Approach 2:
The patent employs a dynamic attachment process where the decorative body pivots from an installed position to a locked position. During installation, the body can move freely until the locking portions engage, providing ease of installation. Once locked, the body becomes stable with restricted movement, achieving both objectives through a dynamic transition.

AI summary
A vehicle seat including: a decorative body attached to a side portion of a seat cushion and including a first locking portion provided to a rear side and a second locking portion provided to a front side; and a cushion side frame including a first locked portion and a second locked portion, wherein the first locking portion is configured to restrict the decorative body from moving in a seat width direction and allow a front end portion side of the decorative body to be pivoted in an upper and lower direction about the first locked portion when the first locking portion is locked to the first locked portion from the front side, and wherein the second locking portion is configured to be locked to the second locked portion from an upper side when the front end portion side of the decorative body is pivoted downward.
