1. A vehicle seat comprising:
- a seat cushion, which is configured for an occupant to be seated thereon;
a seat back, which is configured for an occupant seated on the seat cushion to lean against;
a blower; and
a duct connected to the blower, that sends or exhausts air from the blower to the seat cushion or the seat back,wherein the seat cushion has a urethane pad and a seat cover which covers a surface of the urethane pad,wherein in the urethane pad, a through hole with one end connected to the duct, and a groove extending in a longitudinal direction with a longitudinally extending opening extending continuously in the longitudinal direction of the groove along a surface covered with the seat cover, connected to another end of the through hole, are formed,wherein the groove has a cross-sectional shape in a plane perpendicular to the longitudinal direction where the longitudinally extending opening has a width narrower than a space part inside the groove on an inner side of the urethane pad, andwherein large opening-size parts are provided spaced along the longitudinal direction of the longitudinally extending opening at the surface of the urethane pad covered with the seat cover, the large opening-size parts having a width larger than parts of the longitudinally extending opening not provided with the large opening-size parts.

Abstract
To make a vehicle seat having functionality for blowing air from the surface of the seat feel comfortable for an occupant to sit on without feeling recesses of opening parts of air-blowing grooves thereon, while ensuring that the efficiency of blowing air to the seat surface is kept high. In the vehicle seat, a urethane pad of a seat cushion and a urethane pad of a seat back have through-holes and groove parts formed thereon, wherein the through-holes are connected to a duct at one end, and the groove parts have openings along a surface covered by a seat cover and are connected to the other ends of the through-holes. Each groove part is formed such that the respective opening has a narrower cross-sectional shape than an internal space of the groove part on the inner side of the urethane pad for the seat cushion/seat back.
