SELF-ADJUSTING VEHICLE SEAT

摘要

Described are seat units with a seat pan (2) coupled to a seat back (3), inflatable cushions (5) positioned proximate the seat pan and/or the seat back, inflatable airbags (6) positioned proximate the inflatable cushions (5), and a pressure sensor (9) positioned over at least one of the seat pan (2) and the seat back (3) so that the inflatable cushions (5) and the inflatable airbags (6) are substantially covered by the pressure sensor (9). The pressure sensor (9) is configured to generate a pressure map, and a control unit (11) is configured to analyze the pressure map for at least one pressure irregularity within a pressure distribution, and adjust a pressure inside at least one of the inflatable cushions (5) and/or the inflatable airbags (6) to minimize the pressure irregularity within the pressure distribution.
