Abstract:
1. A seat assembly, comprising: a seat configured to be installed in a motor vehicle, the seat including a seat cushion and a seat back; a first heating element provided in an upper section of a backrest in the seat back and configured to have a first thermal conductance to a passenger; a second heating element provided in a lower section of the backrest in the seat back and configured to have a second thermal conductance to the passenger that is lower than the first thermal conductance; and a third heating element provided in a seat front section of the seat cushion and configured to have a third thermal conductance to the passenger that is higher than the second thermal conductance, wherein a heat generation density of the first heating element is lower than a heat generation density of the second heating element such that power consumption of the first heating element is reduced relative to power consumption of the second heating element to conserve motor vehicle power, and wherein the heat generation density of the second heating element is lower than a heat generation density of the third heating element such that power consumption of the second heating element is reduced relative to power consumption of the third heating element to conserve motor vehicle power.
