Tether Hook Bracket Rebound Blocker Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tether hook systems fail to maintain the connection of child seats during external force events followed by rebound events, leading to potential detachment and safety concerns.
Innovation Solution
A tether hook bracket with a body structure attachment portion, a tether hook connection portion, and a tether hook rebound blocker portion, which includes a deformation portion that deforms during external force events to maintain the connection of the tether hook to the bracket during rebound events, preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional tether hook bracket is used without a rebound blocker, then the structure is simple, but the tether hook may detach during rebound events after external force events
Solution Approach 1:
The tether hook bracket is segmented into distinct functional portions: a body structure attachment portion, a tether hook connection portion, and a tether hook rebound blocker portion. This segmentation allows each portion to perform its specific function independently, with the rebound blocker portion specifically designed to prevent detachment during rebound events without complicating the overall structure.
Solution Approach 2:
The tether hook rebound blocker portion acts as an intermediary element between the body structure attachment portion and the tether hook connection portion. It mediates the forces during rebound events by providing a blocking surface that prevents the tether hook from disengaging, thereby maintaining connection reliability without requiring complete structural redesign.
2Reliability
If a rigid tether hook bracket is used, then the structure is strong, but it cannot deform during external force events to maintain connection
Solution Approach 1:
The tether hook bracket incorporates a deformation portion that transitions the structure from purely rigid to dynamically adaptive. During external force events, the deformation portion allows controlled deformation to absorb energy and maintain the tether hook connection, while the rebound blocker portion provides a static blocking mechanism for rebound events. This dynamic design maintains both strength and reliability under different loading conditions.

AI summary
A tether hook bracket for a vehicle subjectable to an external force event, followed by a rebound event, and having a body structure and a child seat connectable to the body structure via a tether having a tether hook includes a body structure attachment portion, a tether hook connection portion, and a tether hook rebound blocker portion. The body structure attachment portion is configured to be attachable to the body structure. The tether hook connection portion is configured to receive the tether hook, such that the tether hook is connected to the tether hook bracket. The tether hook rebound blocker portion is disposed between the body structure attachment portion and the tether hook connection portion and is configured to maintain the connection of the tether hook to the tether hook bracket when the vehicle is subjected to the rebound event.
