The closed loop reached production four years before the patents claiming it

Bentley's Airline Seat in the 2022 Bentayga extended wheelbase is the case that resets the timing. The seat measures surface temperature and humidity every 25 milliseconds, then decides between heat, ventilation or both across seven levels, which Bentley says uses about 40 percent less power than manual control. A second loop applies 177 pressure changes across six independently inflated zones over three hours. One seat controller runs both, working through three pneumatic valve units.

In 2021 mechanical comfort was the largest area, with 74 publications against 66 in occupant sensing. By the first ten months of 2026 sensing had published 178 against 122 for mechanical. Across the full window the ordering is sensing 653, thermal 570, mechanical 501, integrated 311.

Every stage has turned from a setting into a running loop

The reading widened first. Pressure arrays remain the cheapest substrate, and Continental now runs pressure, deformation and temperature down the seat as a fibre-optic matrix. Capacitance arrays reconstruct body shape as a point cloud, millimetre-wave radar reads heart and breathing through clothing, and cameras and electrodes add face and muscle signals. The seat is one sensor among several, and often not the cheapest.

Voyah's Taishan, launched in China on 18 November 2025 at RMB 379,900 to 509,900, carries 66 sensors in the seat and drives 26 massage points from real-time posture and weight distribution. It also reads speed and steering to pre-position lateral support before a corner.

One automaker now sets the pace

Geely is the largest single named filer in the field, ahead of FAW and Hyundai Motor. Its publication count ran 1, 4, 3, 2, 8 and 19 across the six years, so almost all of it arrived in the last two. Zeekr, its brand, appears on several of the filings.
Research
The seat has stopped being the system boundary

Three migrations run in parallel, and together they turn the seat into a node on someone else's network.

The product being sold is a module, and the patents behind it repair interference between functions

Lear, Gentherm, Adient and Forvia are all now selling assembled comfort modules rather than components. Lear's ComfortMax moved the heater into the trim cover and is integrated with GM from the second quarter of 2025, and its Tunisian plant opened in January 2026 dedicated to heating, ventilation, active cooling, lumbar support, massage, heated steering wheels and occupant detection on one site. Gentherm sells ComfortScale as one thermal and pneumatic module across seat platforms. Adient put a mechanical kneading platform into production in April 2026 on two Chinese models, and Forvia's complete-seat award for the Luxeed brand starts production in August 2026.
#### An aircraft seat design pair patents a lumbar support that folds flat by itself
What it is: A lumbar panel stitched into a three-dimensional shape that the occupant pulls forward with a control on the seat cushion, plus a release that lets it spring back to its flat default position when not in use.

#### Lear's new US grant is about running seat cooling and massage at once without either losing performance
What it is: A granted US patent on a ventilated seat cushion in which the air-distribution passages and the inflatable massage cells sit in separate layers, so inflating the cells does not throttle the airflow.
