Seat Belt Buckle Presenter With Interlocking Anchor Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat belt buckle systems do not adjust with changes in the position of the vehicle seat, making the buckle less accessible and visible, especially when the seat is adjusted vertically.
Innovation Solution
A buckle presenter system that includes an anchor strap and a buckle strap, where the buckle is attached to the buckle strap, which moves with the vehicle seat, and the anchor strap is anchored to the seat adjustment mechanism, ensuring the buckle remains accessible and visible across various seat positions by interlocking with the buckle strap under load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat belt buckle presenter is of uniform length, then the manufacturing is simple, but the buckle is not accessible and visible when the seat position changes
Solution Approach 1:
The buckle presenter is divided into two separate straps: an anchor strap that remains fixed relative to the seat frame, and a buckle strap that moves with the seat. This segmentation allows each component to perform its specific function independently, enabling the buckle to maintain proper positioning as the seat adjusts without requiring the entire presenter to be complex or adjustable.
Solution Approach 2:
The anchor strap acts as an intermediary element between the fixed seat frame and the moving buckle strap. By anchoring one end to the seat frame and allowing the other end to serve as a guide for the buckle strap, it mediates between the stationary structure and the moving component, enabling the buckle to follow seat movement while maintaining proper geometry.
2Stability of the object's composition
If the anchor strap is anchored to the seat frame, then the buckle position stability is improved, but the buckle accessibility when seat adjusts vertically deteriorates
Solution Approach 1:
The system separates the stability function (anchor strap fixed to seat frame) from the movement function (buckle strap moving with seat). This allows the buckle to be stable relative to the seat structure while simultaneously being accessible as the seat adjusts, because the two straps respond differently to seat movement.
Solution Approach 2:
The anchor strap is configured with specific attachment points and routing that allow it to dynamically adapt to seat position changes. When the seat moves vertically, the anchor strap's geometry and routing enable the buckle strap to follow the movement while the anchor strap itself maintains its structural stability and proper tension.

AI summary
A buckle presenter for moving a seat belt buckle with a vehicle seat of a vehicle is provided. The vehicle seat has a seat frame connected to a seat adjustment mechanism that moves the vehicle seat. The buckle presenter includes an anchor strap and a buckle strap. The anchor strap is anchored with respect to the vehicle seat such that it is substantially restricted from moving when the vehicle seat is being adjusted vertically. The buckle is attachable to the buckle strap, which is connectable to the vehicle seat such that it moves with the vehicle seat when it is being adjusted vertically. The buckle strap is configured to move along the anchor strap. When a load is applied to the seat belt buckle, the buckle strap and the anchor strap are configured to interlock such that the buckle strap is substantially restricted from moving vertically.
