Vehicle Buckle Assembly Web Plate Peel Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle buckle assemblies lack a secure and flexible integration of webbing straps with buckle members and anchor brackets, leading to potential peeling and reduced flexibility during seatbelt usage.
Innovation Solution
A buckle assembly comprising a buckle member with a connector, an anchor bracket, and a webbing strap with a loop portion that interconnects two strap portions, forming a joint and utilizing a web plate to resist peeling, ensuring flexibility and secure attachment to a vehicle panel and seat member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional buckle assembly design is used, then the structure is simple, but the webbing strap peels during seatbelt usage
Solution Approach 1:
The patent introduces a web plate positioned behind the webbing strap to create a multi-layered structure. This additional dimension (depth layer) prevents peeling by distributing forces across multiple planes, transforming a single-plane attachment into a three-dimensional assembly that resists peeling forces more effectively.
Solution Approach 2:
The buckle assembly combines multiple materials with different properties: the webbing strap (flexible textile), the web plate (rigid structural element), the buckle member (metal connector), and the anchor bracket (structural fastener). This composite construction leverages the strengths of each material to achieve both flexibility and peel resistance simultaneously.
2Reliability
If the webbing strap is tightly secured to prevent peeling, then reliability improves, but flexibility during usage is reduced
Solution Approach 1:
The webbing strap is divided into distinct functional segments: the first strap portion that interfaces with the buckle member, the web plate that provides structural support, and the second strap portion that extends to the anchor bracket. This segmentation allows each portion to be optimized independently - the first portion can be flexible for ease of insertion while the web plate provides rigidity to prevent peeling.
Solution Approach 2:
The web plate acts as an intermediary element between the webbing strap and the anchor bracket. It mediates the conflicting requirements by providing a rigid backing that prevents peeling while allowing the webbing strap itself to remain flexible and maintain its ease of operation characteristics.

AI summary
A buckle assembly for a vehicle includes a buckle member, an anchor bracket, and a webbing strap. The buckle member includes a connector that defines a buckle opening. The anchor bracket is operatively disposed in adjacent relationship to the buckle member and is configured for attachment to the vehicle. The anchor bracket defines a anchor opening. The webbing strap extends between a first strap portion and a second strap portion to form a loop portion therebetween. The webbing strap presents a first side and a second side, opposing the first side. The loop portion of the webbing strap extends through the buckle opening of the connector and the anchor opening of the anchor bracket. The first side of the first strap portion and the first side of the second strap portion are disposed in facing relationship to one another and a joint is formed therebetween.
