Abstract: A headrest includes a first configuration section comprising a hard urethane and formed with an indentation in a front face, the indentation enabling entry of a supported portion, and the supported portion being a location corresponding to an occipital bone of the head of the seated occupant; and a second configuration section comprising a soft urethane having a lower rigidity than the hard urethane, the second configuration section being provided at the indentation so as to be deformed by the supported portion. Part of the first configuration section, which is a bottom face of the indentation, is configured by a left-right pair of head support faces that support the supported portion and that are connected together at a connection location having a straight line shape. An angle formed between cross-sections of the left and right head support faces when sectioned along a plane perpendicular to the connection location is a first angle that is from 37.2° to 143°.

Abstract: A vehicle seat includes a seat cushion, a seatback, a headrest, and a head support section. The seat cushion is configured so as to support the buttocks of a seated occupant from a seat lower side. The seatback is configured so as to support the back of the seated occupant from a seat rear side. The headrest is configured so as to support the head of the seated occupant from the seat rear side. The head support section is provided to the headrest and is configured so as to support a location corresponding the occipital bone of the head of the seated occupant from a seat left-right direction, and is also configured so as to support the location in a forward direction and in a seat obliquely upward direction from the seat rear side.

Abstract: A hand rest device, including: a hand rest that is disposed at a front side of a seat of a vehicle, the hand rest being disposed at a usage position for supporting a hand of a vehicle occupant seated at the seat and an adjustment mechanism that adjusts a height of the usage position of the hand rest.

Abstract: The armrest of a vehicle seat is provided with a first armrest and a second armrest. The first armrest includes a first end portion rotatably supported by a side portion of a seatback, and selectively adopts a not-in-use position in which the first armrest is positioned so as to extend toward a seat upper side at the seatback side portion, and an in-use position in which the first armrest is positioned so as to be rotated from the seatback side portion toward a seat front side, so as to extend toward the seat front side.

Abstract: At a vehicle seat, resistance to relative displacement of a passenger in a left-right direction is larger at both left-right direction side portions of a front surface of an upper portion of a backrest than at a left-right direction central portion. Further, a seat cushion has left and right side reinforcing portions that reinforce portions of a cushion pad from outer sides in a left-right direction, and from obliquely lower sides, of front-rear direction central portions of thigh portions of the passenger, and left and right lower surface reinforcing portions that reinforce portions of a lower surface of the cushion pad at outer sides in a left-right direction, and at obliquely lower sides, of buttock portions of the passenger.
