Seatback Bracket With Hinge Mount For Adjustable Entertainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting solutions for in-vehicle entertainment systems interfere with vehicle factory headrests, restrict movement, or add unnecessary weight, and lack adjustable viewing angles for electronic displays.
Innovation Solution
A mounting bracket system comprising a base bracket, inner brackets, and a cover that allows for adjustable headrest post openings, a hinge mount for adjustable viewing angles, and secure attachment to seatback posts, enabling flexible installation and adjustable display orientation without interfering with factory headrest mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting bracket is installed between the seat and headrest, then the entertainment system can be securely mounted, but the factory headrest movement may be restricted
Solution Approach 1:
The mounting bracket is divided into multiple components: a base bracket that attaches to the seatback, inner brackets with grooves that receive posts, and a cover that conceals the assembly. This segmentation allows the headrest posts to pass through the grooves freely while the bracket structure remains securely attached to the seatback, resolving the contradiction between mounting security and headrest movement.
Solution Approach 2:
The mounting bracket acts as an intermediary structure between the seatback and the entertainment system. It provides secure attachment points to the seatback while creating clearances and openings that allow the headrest mechanism to operate independently without restriction, thus mediating between the mounting requirement and the headrest movement requirement.
2Ease of manufacture
If existing mounting solutions are used, then the entertainment system can be installed, but unnecessary weight is added to the vehicle
Solution Approach 1:
The mounting bracket uses local quality by concentrating structural strength only where needed - at the attachment points to the seatback and at the post receiving grooves. The rest of the structure uses minimal material, and the cover provides concealment without adding structural weight. This localized strengthening approach achieves installation capability while minimizing overall weight.
3Device complexity
If a fixed mounting structure is used, then installation is simple, but adjustable viewing angles for electronic displays cannot be provided
Solution Approach 1:
The mounting bracket incorporates a hinge mechanism that allows the electronic display to be adjusted to different viewing angles. This dynamic element is integrated into the bracket structure, enabling the display to rotate or tilt while maintaining secure attachment. The base bracket and inner brackets provide stable mounting, while the hinge adds the necessary adaptability for viewing angle adjustment without significantly increasing overall complexity.

AI summary
A mounting bracket for seatback in-vehicle entertainment including: a base bracket including posts and a hinge mount; a first inner bracket including grooves corresponding to the posts and, when each of the posts is received in its corresponding groove, a first opening for a first headrest post is formed and a second opening for a second headrest post is formed; a second inner bracket including openings corresponding to the posts, a third opening overlapping the first opening and a fourth opening overlapping the second opening; and a cover including fifth and sixth openings and, when the cover is disposed over the second inner bracket, first inner bracket and base bracket, the fifth opening overlaps the third and first openings to permit the first headrest post to pass therethrough and the sixth opening overlaps the fourth and second openings to permit the second headrest post to pass therethrough.
