Seat Cushion Buckle Holding Structure With Hidden Elastic Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buckle holding structures for vehicle seats expose the annular band on the seating surface, compromising appearance and reliability in returning the buckle to the seat cushion.
Innovation Solution
A buckle holding structure featuring an elastic band folded in a U shape with both ends fixed to the rear end of the seat cushion, creating a gap for the buckle to be caught and guided back onto the cushion, ensuring the buckle remains hidden and securely in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an annular band is mounted on the rear portion of the upper surface of the seat cushion to hold the buckle, then the buckle can be reliably returned to the seat cushion, but the annular band is exposed to the seating surface which compromises appearance
Solution Approach 1:
The annular band is extracted from the seating surface and relocated to the rear end of the seat cushion. By fixing both ends of the band to the rear end of the seat cushion, the band is positioned away from the seating surface, eliminating exposure while maintaining the buckle return function through the elastic contraction mechanism.
2Shape
If the annular band is fixed to the rear end of the seat cushion to improve appearance, then the band is not exposed, but the width of the receiving surface for the buckle is reduced
Solution Approach 1:
The band is configured in a U-shape with both ends fixed to the rear end of the seat cushion, creating a three-dimensional structure. This dimensional arrangement allows the band to extend forward and form a wide receiving surface area at the front, while the fixed ends at the rear maintain a compact appearance and do not expose the band on the seating surface.
3Shape
If both ends of the band are fixed to the rear end of the seat cushion, then the appearance is improved and the band is hidden, but the structural complexity increases
Solution Approach 1:
The band is made of elastic material with flexible properties, allowing it to be stretched when the seat cushion is in the tip-up state and contracted when in the seatable state. This flexibility simplifies the structure by eliminating the need for complex mechanical components, while both ends are simply fixed to the rear end of the seat cushion to achieve the desired appearance.

Function Achieved in This Case
The solution provides a visually appealing and reliable mechanism for the buckle to return to the seat cushion, enhancing user convenience and maintaining the buckle's position without exposure, ensuring easy access and secure fastening of the seat belt.
Implementation Method 1
a band that has elasticity, has a predetermined width, and is folded in a U shape to form a folded portion

AI summary
A buckle holding structure for holding a buckle unit on a seat cushion, the buckle unit having: a belt of which one end is fixed to a vehicle body; and a buckle fixed to the other end of the belt, the buckle holding structure including: a band that has elasticity, has a predetermined width, and is folded in a U shape to form a folded portion, wherein both ends of the band are fixed to a rear end of the seat cushion so as to be disposed on the same plane in a width direction of the band; the belt of the buckle unit is inserted into a gap formed between both ends of the band, which is fixed to the rear end of the seat cushion, and the folded portion; and the buckle is caught by the folded portion.
