Abstract

A vehicle seat includes a seat back, a seat cushion, and a base. The seat cushion has a rear cushion portion, a front cushion portion, and a shaft support portion. The rear cushion portion has a rear upper surface and a front surface. The front cushion portion has a front upper surface and a rear surface. The shaft support portion extends in a seat width direction at a position below the front upper surface and forward of the rear surface. The shaft support portion is configured to support the front cushion portion so as to be pivotable. The front cushion portion pivots upward around the shaft support portion as the center of rotation, so that the front cushion portion is positioned in a tipped-up state.

a shaft support portion extending in a seat width direction at a position below the front upper surface and forward of the rear surface, the shaft support portion being configured to support the front cushion portion so as to be pivotable, wherein

in a sittable state in which the rear surface faces the front surface, the front upper surface and the rear upper surface form a sitting face, and
when the front cushion portion pivots upward around the shaft support portion as a center of rotation between the sittable state and a tipped up state, a front end surface of the front cushion portion is moved rearwardly and a rear surface of the rear cushion portion is spaced apart from the front surface of the rear cushion portion.

2. The vehicle seat according to claim 1 , wherein
when the front surface and the rear surface are seen from a direction parallel to the seat width direction,
the front surface has a concave surface shape that is curved such that an intermediate portion in an up-down direction of the front surface is recessed rearward, and
the rear surface has a convex surface shape that is curved such that an intermediate portion in an up-down direction of the rear surface bulges rearward.

the rear surface comprises:
a second upper portion extending downward from the rear end of the front upper surface, a second intermediate portion extending rearward from an end of the second upper portion that is located on an opposite side of the front upper surface, and a second lower portion extending downward from an end of the second intermediate portion that is located on an opposite side of the second upper portion,

and
in the sittable state, the first upper portion and the second upper portion face each other, the first intermediate portion and the second intermediate portion face each other, and the first lower portion and the second lower portion face each other.
