Since the control switch 13 which can be pressed on is provided in each heating zone 12, the corresponding heating unit 11 can be selectively switched on according to the control switch 13 which is switched on. The heating unit 11 may cover as many heating zones 12 as possible so that the heating zones 12 generating heat may be controlled, and the heating zones 12 may be activated in tandem to accommodate the sitting region of the occupant. In principle, the more areas of sitting contact, the more parts are automatically activated, greatly improving the intelligence.
