Abstract

A reclining apparatus for a rear seat in a car may include a plurality of links provided on both sides of a cushion frame and each being rotatably coupled at both sides to the cushion frame or a car floor, and a locking module configured to couple a back frame hinge-connected to the cushion frame with a car body and slidably and rotatably connected with the back frame so as to allow the back frame to tilt at a variable angle in response to movement of the cushion frame by the rotation of the links.

First claim

What is claimed is:

1. A reclining apparatus for a rear seat in a car, the apparatus comprising:
a plurality of links provided on both sides of a cushion frame and each being rotatably coupled at both sides to the cushion frame or a car floor;
a locking module configured to couple a back frame hinge-connected to the cushion frame with a car body and slidably and rotatably connected with the back frame so as to allow the back frame to tilt at a variable angle in response to movement of the cushion frame by the rotation of the links,
wherein the locking module comprises:
a striker coupled to at least one of the back frame and the car body; and
a latch coupled to another of the back frame and the car body so as to engage with or disengage from the striker, and

wherein the striker is rotatably and slidably coupled to the back frame and the latch is coupled to the car body; and

a connection bracket that is fixed to the back frame and is rotatably and slidably coupled to the striker at one side thereof.

2. The reclining apparatus according to claim 1 , wherein at least one link of the plurality of links is provided, on one side thereof to be coupled with the floor, with an elastic part serving to assist in rotation of the link.

3. The reclining apparatus according to claim 2 , wherein the back frame is coupled to one side of the both sides of the cushion frame at one end thereof, and the elastic part assists in the rotation of the link for the movement towards another side of the both sides of the cushion frame.

4. The reclining apparatus according to claim 1 , further comprising:
a lead screw provided between the cushion frame and the floor; and
a drive apparatus coupled with one side of the lead screw so as to rotate the lead screw according to an operating signal,
wherein another side of the lead screw and the drive apparatus are respectively coupled to either the cushion frame or the floor so as to move the cushion frame as the lead screw rotates.

5. The reclining apparatus according to claim 1 , wherein the connection bracket is provided on an end thereof with a vertical slit, and the striker is slidably and rotatably coupled to the end of the connection bracket by a hinge pin to be inserted into the slit.

6. The reclining apparatus according to claim 1 , wherein the back frame is rotatably coupled to the cushion frame at a lower end thereof, and is foldable when the striker and the latch are disengaged from each other.
