Vehicle Seat Headrest Neck Support With Pneumatic Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck supports in vehicle seats are fixed and cannot be adjusted to accommodate the varying distances between the neck and head of different users, leading to suboptimal comfort and personalization.
Innovation Solution
A neck support system with an airbag between a main mounting frame and a support assembly, allowing the support assembly to slide forward and rearward by inflating and deflating the airbag, and optionally incorporating massage airbags for enhanced comfort, with an emergency exhaust valve for collision safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the neck support is made as a fixed member integrated into the headrest, then the structure is simple and reliable, but it cannot be adjusted to accommodate different users' neck positions
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed neck support into a movable one. The support assembly is designed to slide along the front-rear direction within the through hole of the main mounting frame, allowing dynamic adjustment of the neck support position to accommodate different users' needs while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent uses pneumatics by introducing an airbag between the main mounting frame and the support assembly. The airbag can be inflated to push the support assembly forward and deflated to allow it to move rearward, providing a simple yet effective mechanism for adjusting the neck support position without complex mechanical linkages.
2Adaptability or versatility
If the neck support is made adjustable with sliding mechanism, then it can adapt to different users, but the structure becomes more complex
Solution Approach 1:
The patent employs pneumatic technology by using an airbag as the actuating mechanism for the sliding support assembly. The airbag connects to an air supply component that can inflate and deflate it, providing a simple control mechanism for adjusting the neck support position without requiring complex mechanical linkages, motors, or actuators.
Solution Approach 2:
The patent applies parameter changes by utilizing the volume and pressure changes of the airbag to drive the movement of the support assembly. By changing the airbag's inflation state (volume and pressure parameters), the system achieves positional adjustment of the neck support, transforming a mechanical adjustment problem into a pneumatic parameter control problem.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables independent adjustment of the neck support to meet individual user needs, provides enhanced comfort through adjustable support and massage, and reduces injury risk during collisions by collapsing the airbag.
Implementation Method 1
an airbag is provided between the main mounting frame and the support assembly; the airbag is connected to an air supply component; the air supply component is used to inflate and deflate the airbag; the airbag is inflated and expanded to push the support assembly to move forward; and the airbag is deflated and contracted to pull the support assembly to move rearward

AI summary
A neck support and a vehicle seat headrest are provided. The neck support may have a main mounting frame and a support assembly. The main mounting frame may be integrated in a headrest. The main mounting frame may be provided with a through hole extending in a front-rear direction of the headrest. A front portion of the support assembly may be used to support an occupant's neck, and a rear portion of the support assembly may be slidably assembled in the through hole. An airbag may be provided between the main mounting frame and the support assembly. The airbag may be connected to an air supply component. The air supply component may be used to inflate and deflate the airbag. The airbag may be inflated and expanded to push the support assembly to move forward. The airbag is deflated and contracted to pull the support assembly to move rearward.
