GM has filed a patent application for a vertically adjustable seatback height system. The application was assigned patent number US 2024/0270130 A1 with the United States Patent and Trademark Office (USPTO) and was published on August 15th, 2024. The patent application was originally filed on February 9th, 2023, and lists several South Korean engineers as the inventors, including Jongphill Kim, Namjin Hur, and Jaeyoun Cho.
This vertically adjustable seatback system described in the new GM patent application allows for the seatback of a vehicle to be selectively adjusted up and down, independent of other seat movements. The system incorporates several frame components. One frame component is attached to the seat base, while a second frame component is connected to the first and can move vertically relative to the seat base. This movement is controlled by an adjustment mechanism that includes gears and knobs, allowing the user to manually change the seatback’s height. The mechanism uses two adjustors connected to the frame components, which rotate to move the seatback to the desired position.
Additionally, the system could feature an electric motor to make adjustments, allowing users to shift the seatback vertically without manually turning a knob. A locking mechanism prevents unintended movement of the seatback, ensuring safety during driving.
This adjustable seatback system could offer greater comfort for drivers and passengers, and is particularly beneficial for individuals with different torso lengths. Individuals with longer torsos may lack proper headrest alignment, while those with shorter torsos may not have adequate shoulder or lumbar support. By adjusting the height of the seatback, this system allows users to fine-tune their seating position to achieve better posture and support, improving overall driving comfort in the process.
Unlike conventional vehicle seats that allow adjustments primarily in the forward-backward or tilt directions, this system introduces a vertical movement for the seatback. Most current systems lack the ability to raise or lower the seatback independently from the seat cushion or the overall seat height adjustment. This system adds a new dimension of customization, focusing on better ergonomic support for a wider range of body types and seating preferences.

“For added comfort”???
How about returning to the days of having a head rest that actually COMFORTABLY supported your head while it prevented whiplash injuries?
Nowadays, I have yet to find ANY vehicle that still is designed with a comfortable head rest.
Its as if they make the head rest a deterrent to falling asleep at the wheel. Ignoring the passenger who is obviously not driving!
$47,000 vehicle and I didn’t even get lumbar support adjustments thanks to “constraint”. Lost 3 other features Buick web advisor told me was still available and dealer said it was equipped with… So while yes I’d like this feature, I much rather not be up sold on non existent features!
Ah, yes. It had to happen eventually. The days of mum using a cushion to get high enough to see through the windshield are finally drawing to a close.
