Differential thermal conditioning of a vehicle seat

摘要

Differential thermal conditioning of vehicle seat zones is achieved with convenient adjustment of a seat temperature differential for optimizing the thermal comfort of the seat occupant. Two or more thermoelectric units (16, 18, 20, 50) supply conditioned air to different zones of the seat (10), and the temperature differential between specified zones of the seat (10) is set by an occupant-adjustable control input (40).
