1. A vehicle seat flip-up mechanism that is capable of switching a posture of a seat cushion between a normal sitting posture and a stowed posture where the seat cushion is stowed while being inclined forward, the vehicle seat flip-up mechanism comprising:
-
a pair of links that is formed by elongated bodies extending in a front to back direction while being separated from each other in a seat width direction; a pair of mounting brackets that is attached to ends of the pair of links and supports the seat cushion; a connection member that is installed in the pair of mounting brackets; a pair of support mechanisms that rotatably supports the pair of links; and a mounting plate that is disposed below the pair of support mechanisms and is locked to a vehicle body floor, wherein; the mounting plate extends rearward relative to the links and comprises; a fixing member that extends in the seat width direction; and a mounting member that; overlaps with one end of the fixing member; is disposed along an extension direction of the link; and comprises a mounting surface portion that contacts the vehicle body floor; and an intersection point in a top view between the connection member and an imaginary line connecting an apex at an inside of a rear end of the mounting surface portion in the seat width direction and an apex not overlapping the mounting member in a rear end of the fixing member is disposed nearer an other end of the fixing member compared to a center portion of the connection member in an extension direction. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
wherein; the base bracket includes a fixing portion fixed to the fixing member and an upright wall portion bent from the fixing portion; and the guide member is disposed at an inside of the upright wall portion in the seat width direction.

12. A vehicle seat comprising:
-
the vehicle seat flip-up mechanism according to claim 1; and a cover member that covers the flip-up mechanism.
-
-
13. The vehicle seat according to claim 12, wherein:
-
a stowed position in which the seat cushion is held in the stowed posture is located at a front side relative to a sitting position in which the seat cushion is held at the sitting posture; the flip-up mechanism includes a biasing member that biases the link and performs an operation of rotating the link forward by a biasing force of the biasing member as an operation of moving the seat cushion from the sitting position toward the stowed position; and the cover member includes a biasing member cover portion that covers the biasing member.
-
-
14. The vehicle seat according to claim 13,
wherein the biasing member cover portion is mounted to be rotatable forward along with a forward rotation of the link. -
15. The vehicle seat according to claim 14, further comprising:
-
a biasing spring that biases the biasing member cover portion, wherein; the link contacts the biasing member cover portion during the forward rotation; when a forward direction is set as a first direction and a rearward direction is set as a second direction in a rotation direction of the biasing member cover portion, the biasing spring biases the biasing member cover portion in the second direction; and when the link further rotates forward while contacting the biasing member cover portion, the link presses the biasing member cover portion in the first direction to rotate the biasing member cover portion forward against a biasing force of the biasing spring.
