Folding seat apparatus for vehicle
A folding seat apparatus for a vehicle comprising a slide mechanism for slidably moving a seat in a front-and-rear direction, and a pop-up mechanism for popping up a seat cushion. The slide mechanism and pop-up mechanism are connected to the control lever. The controller controls the actuator so that the control lever rotates in the forward or reverse direction. The pop-up mechanism is unlocked by rotating the control lever in a first direction, and the slide mechanism is unlocked by rotating the control lever in a second direction.
1. A folding seat apparatus for a vehicle, comprising:
a slide mechanism for moving a seat having a seatback and a seat cushion in a front-and-rear direction of the vehicle; and
a pop-up mechanism for popping the seat cushion upward,
the apparatus further comprising:
a control lever connected to the slide mechanism and pop-up mechanism;
an actuator for rotating the control lever in a first direction in order to unlock the pop-up mechanism, and for rotating the control lever in a second direction in order to unlock the slide mechanism;
a pop-up detector for detecting that the seat cushion has popped up; and
a controller for controlling the actuator such that the control lever rotates in the first direction, and controlling the actuator so as to switch the rotation of the control lever from the first direction to the second direction on the basis of a detection signal from the pop-up detector; wherein
the controller controls the actuator so as to unlock the pop-up mechanism and then to unlock the slide mechanism.
2. The seat apparatus of claim 1 , further comprising a forward-tilt mechanism for tilting the seatback in the forward direction of the vehicle, wherein
the control lever comprises first, second, and third branching arms connected to the forward-tilt mechanism, the pop-up mechanism, and the slide mechanism, respectively; and
the pop-up mechanism is unlocked by the second branching arm, and the forward-tilt mechanism is unlocked by the first branching arm when the control lever is rotated in the first direction.
3. The seat apparatus of claim 1 , wherein the seat cushion is moveably disposed in slide rails by way of a base, so as to slidably move the seat in the forward direction of the vehicle, and the control lever is disposed on the base.
4. The seat apparatus of claim 2 , wherein the control lever is formed so that the first, second, and third arms form a Y-shape.
5. The seat apparatus of claim 2 , wherein the control lever is disposed on an output shaft of the actuator, and the forward-tilt mechanism, the pop-up mechanism, and the slide mechanism are connected to the first, second, and third branching arms by way of control cables, respectively.
