Abstract

The application discloses a seat, which comprises a seat cushion body, a backrest body and a locking assembly. The seat cushion body is adapted to be slidably connected with a vehicle body, and the backrest body is rotationally connected with the seat cushion body. The locking assembly comprises a first connecting rod, a second connecting rod and a backrest lock. The two ends of the first connecting rod are respectively hingedly connected with the seat cushion body and the second connecting rod. The end of the second connecting rod, which is away from the first connecting rod, is adapted to be hingedly connected with the vehicle body. The backrest lock is arranged on the backrest body and has a locking state of being connected with the first connecting rod and an unlocking state of being separated from the first connecting rod. When the backrest lock is in the unlocking state, the backrest body rotates around the seat cushion body, so that the backrest body is forwardly turned. After the backrest body is lifted, the backrest lock can be locked with the first connecting rod without moving the position of the seat cushion body in the vehicle body, so that the operation is convenient and simple.
