General Motors has secured a patent for an unusual vehicle headrest that can support the head not just from behind, but from both sides. Hinged “wings” sit at the edges of the padded center section: the driver or passenger can leave them open or pull them closer to the head for firmer lateral support.

Patent No. 12,715,351 was granted to GM on August 25, 2026. The wings lock into several positions through ratcheting mechanisms with toothed gears, latches, and springs. In one version, both sides can move together symmetrically. The design isn’t just about comfort — the patent specifically describes head support during sudden changes in direction.

An even more interesting scenario plays out during hard braking. GM describes two ways this can work. In the fully mechanical version, a built-in mass generates inertial force that acts on the wings. In the other, a sensor detects longitudinal acceleration or braking, and an electronic control unit activates solenoids. The mechanism can release the latches and return the side elements to a flat position.

There’s an important nuance about the legal status of the filing. GM applied for the patent on June 27, 2024, and its publication, US20260001467A1, appeared on January 1, 2026. The number US 12,715,351 B2 belongs to the granted patent, which the company received on August 25.

The rights holder is listed as GM Global Technology Operations LLC, with engineers Leeyong Choi, Seungil Lim, and Soyeon Kim named as inventors. The existence of the patent doesn’t mean such headrests are already headed for specific Chevrolet, Cadillac, GMC, or Buick models. The document names no model, no platform, and no timeline.

Automakers regularly patent designs that never make it to production, so a headline claiming “your next GM vehicle will get this headrest” would be premature. What’s confirmed is that the company has secured a design for adjustable lateral head support that combines the standard headrest function with extra bracing during side-to-side movement and a possible automatic response to hard braking.
