Rear Seat Tether Bracket Layout for Adjustable Child Seat Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle tether structures are typically located at the juncture of a lower seat portion and an upright seat portion of a rear seat, which may not provide optimal positioning for securing child seats or accommodating various seat orientations.
Innovation Solution
A tether structure is positioned at or proximate the upper end of an upright seat portion of a rear seat, featuring a tether bracket with an upright and horizontal portion, including tether receiving openings, and is removably attached to the vehicle body structure, allowing for secure attachment of child seats and versatile use with adjustable seat orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tether structure is located at the juncture of lower seat portion and upright seat portion, then the structure is simple and easy to manufacture, but the positioning is not optimal for securing child seats
Solution Approach 1:
The tether bracket is divided into two distinct portions: an upright portion that attaches to the vehicle body structure and a horizontal portion that provides tether receiving openings. This segmentation allows each portion to be optimized for its specific function, improving child seat positioning while maintaining structural simplicity
Solution Approach 2:
The tether bracket transitions from a single-point attachment to a two-dimensional structure with both upright and horizontal portions. This dimensional change enables the bracket to extend toward the upper end of the upright seat portion, providing optimal positioning for child seat attachment without excessive structural complexity
2Adaptability or versatility
If the tether bracket is removably attached to the upright wall proximate the upper end of the seat, then the adaptability for various seat orientations is improved, but the manufacturing complexity increases
Solution Approach 1:
The tether bracket employs a removable attachment mechanism that allows it to be installed and removed from the upright wall. This dynamic capability enables the bracket to accommodate various seat orientations and positions while maintaining a relatively simple manufacturing process through standardized attachment interfaces
3Ease of operation
If the horizontal portion includes tether receiving openings for child seat attachment, then the ease of operation for securing child seats is improved, but the device complexity increases
Solution Approach 1:
The horizontal portion of the tether bracket incorporates tether receiving openings that serve as a universal attachment interface for child seats. This multi-functional design element simplifies the operation of securing child seats while adding minimal structural complexity, as the openings can accommodate various tether configurations

AI summary
A vehicle tether structure includes a vehicle body structure, a seat and a tether bracket. The vehicle body structure includes an upright wall that at least partially defines a passenger compartment. The seat is installed to the passenger compartment adjacent to the upright wall. The tether bracket has an upright portion that is removably attached to the upright wall proximate an upper end of the seat. The tether bracket also has a horizontal portion that includes tether receiving openings for attachment thereto by a child seat.
