Abstract

A vehicle seat includes a seat cushion and a seatback. The seat cushion includes a pad having a groove, a plurality of seat covers for covering the pad surface, and a suspending member for connecting two of the plurality of seat covers, and fixing the two seat covers to the pad inside the groove formed in the pad. A plurality of minute holes are formed in the suspending member between a part connected to one of the two seat covers and a part connected to the other seat cover for ventilation between an inside and an outside of the groove formed in the pad with respect to the suspending member. This secures ventilation performance of the seat cover surface even when the occupant is seated on the vehicle seat.

Claims

1. A vehicle seat, comprising:

a seat cushion, and

a seatback,

wherein the seat cushion includes;
