Abstract

A vehicle seat includes a support leg connected to a floor to be pivotable about a first axis extending in a horizontal direction; a seat cushion connected to the support leg to be pivotable about a second axis which is parallel to the first axis; a first coupling device provided on the support leg and configured to be detachably coupled with a first coupling part provided on the floor; and a second coupling device provided on the seat cushion and configured to be detachably coupled with a second coupling part provided on the floor. The seat cushion is movable between a stowed position in which the seat cushion is in a lowest position, a first use position in which the first coupling device is coupled with the first coupling part, and a second use position in which the second coupling device is coupled with the second coupling part.

First claim

1 . A vehicle seat, comprising:
a support leg connected to a vehicle body to be pivotable about a first axis extending in a horizontal direction; a seat cushion connected to the support leg to be pivotable about a second axis which is parallel to the first axis; a first coupling device provided on the support leg and configured to be detachably coupled with a first coupling part provided on the vehicle body; and a second coupling device provided on the seat cushion and configured to be detachably coupled with a second coupling part provided on the vehicle body, wherein the seat cushion is movable between a stowed position in which the seat cushion is in a lowest position, a first use position in which the first coupling device is coupled with the first coupling part, and a second use position in which the second coupling device is coupled with the second coupling part.

2 . The vehicle seat according to claim 1 , wherein the seat cushion in the second use position is disposed higher than the seat cushion in the stowed position, and
the seat cushion in the first use position is disposed higher than the seat cushion in the second use position.

3 . The vehicle seat according to claim 2 , wherein the vehicle body includes a floor,
the floor includes a floor front portion, a floor middle portion which extends downward from a rear end of the floor front portion, and a floor rear portion which extends rearward from a lower end of the floor middle portion and is disposed lower than the floor front portion, a lower end of the support leg is connected to the floor rear portion to be pivotable about the first axis which extends laterally, the first coupling part is provided on the floor middle portion, and a large part of the seat cushion is disposed above the floor rear portion when in the stowed position and is disposed above the floor front portion when in the first use position.

4 . The vehicle seat according to claim 3 , wherein the second coupling part is provided on a rear end part of the floor front portion or an upper end part of the floor middle portion.

5 . The vehicle seat according to claim 4 , wherein the seat cushion includes a base member connected to the support leg and an upper member supported on the base member, and
the second coupling device is movable in a front-rear direction relative to the base member.

6 . The vehicle seat according to claim 5 , wherein the upper member is supported on the base member via a slide device to be movable in the front-rear direction, and
the second coupling device is provided on the upper member.

7 . The vehicle seat according to claim 5 , wherein the second coupling device is configured to be coupled with the second coupling part when the second coupling device is in a predetermined coupling position with respect to the base member and the seat cushion is in the second use position, and
the second coupling device is configured not to be coupled with the second coupling part when the second coupling device is not in the coupling position and the seat cushion is in the second use position.

8 . The vehicle seat according to claim 3 , wherein when the seat cushion is in the stowed position, an upper surface of the seat cushion is positioned lower than an upper surface of the floor front portion, and
when the seat cushion is in the second use position, the upper surface of the seat cushion is positioned higher than the upper surface of the floor front portion.
