Abstract

The present invention has an object to provide a seat for vehicles in which a seat cushion flip-up mechanism can be space-saving. In a seat for vehicles which has a flip-up mechanism to shift a seat cushion frame (200) disposed on a base part (5) from a normal seating posture (200-1) to a flipped-up posture (200-2), the flip-up mechanism includes: a support leg part (301) having one end connected to the seat cushion frame (200) rotatably around a first rotation shaft (303) and the other end connected to the base part (5) rotatably around a second rotation shaft (302); a guide part (201a) to be engaged with the one end of the support leg part (301) to guide the one end so as to lift the one end; and a coil spring (305) applying a biasing force so as to have the one end guided by the guide part (201a) and flip up a portion (303) connected with the seat cushion frame (200).

Claims

1. A seat for vehicles having a flip-up mechanism to shift a seat cushion disposed on a base part from a normal seating posture to a flipped-up posture, the flip-up mechanism comprising:

a support leg part having one end connected to a frame of the seat cushion rotatably around a first rotation shaft and another end connected to the base part rotatably around a second rotation shaft;

a guide part to be engaged with the one end of the support leg part to guide the one end so as to lift the one end; and

a coil spring applying a biasing force so as to have the one end guided by the guide part and flip up a portion connected with the frame.

2. The seat for vehicles according to claim 1, wherein

in the support leg part, when the seat cushion is in the seating posture, the other end is located on a front side of the base part and the one end extends toward a rear of the base part, and

the coil spring is located between the frame and the support leg part so as to bias the one end of the support leg part forward.

3. The seat for vehicles according to claim 2, wherein the coil spring is located under a seating surface of the seat cushion.

4. The seat for vehicles according to claim 3, further comprising a connecting member being fixed in a middle portion of the frame in a longitudinal direction and having the first rotation shaft and the guide part.

5. The seat for vehicles according to claim 4, wherein

when the seat cushion is in the seating posture, the connecting member has the guide part behind the first rotation shaft, and

the support leg part has a guided part to be engaged with the guide part, on an opposite side of the second rotation shaft with respect to the portion connected with the frame.

6. The seat for vehicles according to claim 5, wherein the coil spring is hooked onto the guided part of the support leg part.
