To ensure good seating comfort by preventing a crewman's body from wobbling.SOLUTION: In a seat cushion 12 of a vehicle seat 10, a spring unit 34 is located on a lower side of a cushion pad 30, and the spring unit 34 is provided with a spring body 50 having a rebound resilience modulus higher than the cushion pad 30. The spring body 50 has both ends in a front-back direction locked to the cushion pad 30, and tightly contacts and covers an undersurface of the cushion pad 30. Consequently, an apparent bound resilience modulus of the cushion pad 30, which is felt by the crewman when seating can be increased, and when the crewman seats and the cushion pad is deformed downward, deformation of the cushion pad is suppressed and the rebound resilience modulus is increased, whereby the crewman's body is prevented from wobbling and good seating comfort can be ensured.SELECTED DRAWING: Figure 2

    【課題】乗員の体のぐらつきを防止して良好な座り心地を確保する。【解決手段】車両用シート10のシートクッション12には、クッションパッド30の下側にバネユニット34が配置されており、バネユニット34には、クッションパッド30よりも反発弾性率の高いバネ体50が設けられている。バネ体50は、前後方向両端がクッションパッド30に係止され、クッションパッド30の下面に緊密に接触して覆っている。これにより、乗員が着座した際に感じる見かけのクッションパッド30の反発弾性率を高くでき、乗員が着座してクッションパッドが下方に変形された際、クッションパッドの変形が抑制され、反発弾性率が高くなることで、乗員の体のぐらつきを防止して良好な座り心地を確保できる。【選択図】図2
