Abstract

A seat air conditioner for a vehicle has a seat having a pad and a blower unit for forcibly blowing conditioned air toward the seat. The pad has an introduction passage for introducing blown air toward a surface of the pad, plural distribution passages communicating with and radially extending from the introduction passage and plural communication passages causing communication among the distribution passages. Each of the distribution passages and the communication passages is formed as a groove in the surface of the pad. Therefore, even when a passenger is seated on the seat, air does not stagnate but flows into the distribution passages extending outside a portion of the seat which contacts with the passenger through the communication passages. As a result, air is smoothly blown out from the seat, and the passenger immediately feels sufficiently warm and comfortable.
