AI Technical Summary

Technical Problem

Existing seat assemblies lack efficient and controlled fluid systems for providing dynamic inflation and deflation of bladders for functions such as massage and lumbar support, with sequential inflation and simultaneous deflation being difficult to achieve.

Method used

A fluid system with a valve assembly and check valves that allows for sequential inflation and simultaneous deflation of multiple bladders, controlled by a controller and actuator, ensuring varying inflation rates and rapid deflation through a three-position valve configuration.

Benefits of technology

Enables dynamic inflation and deflation of bladders for enhanced massage and lumbar support, providing controlled fluid flow and maintaining desired inflation levels, while allowing rapid and simultaneous deflation for improved user comfort and functionality.
