Claims11
A vehicular seat comprising:
- a seat cushion including a pad, the pad including a foamed elastic material;
- a skin member covering a surface of the pad;
- and
- a groove defined in the surface of the pad, the groove having an opening portion and a bottom portion,
- wherein the groove is inclined to a line orthogonal to the surface of the pad,
- wherein the groove is formed proximate a front side of the pad extended in a width direction,
- wherein the bottom portion of the groove extends, relative to the opening portion of the groove, in a direction towards a rear side of the pad such that the bottom portion is closer to the rear side of the pad than the opening portion,
- wherein the groove is configured as a plurality of rows positioned at a front side portion of the seat cushion and extend in a width direction and are aligned in a front and rear direction, and
- wherein a depth of the row is tapered from a front side to a rear side of the seat cushion, the row closest to the front side of the seat cushion has the largest depth.
