Abstract

A foldable seat apparatus for a multi-purpose vehicle is provided. The apparatus includes a seat unit composed of a seat cushion, and a seatback rotatably coupled to the seat cushion, and configured to rotate the seatback and formed to make a horizontal state with the seat cushion according to an operation of an operation lever, a headrest unit mounted on the seatback, and provided to be separable, a mounting guide unit fixed and coupled to the seat cushion; and a pillow mounting unit positioned to be latched to the mounting guide unit to be stored in the seat cushion, drawn out to the outside of the seat cushion by selectively being latch-released from the mounting guide unit in the horizontal state, and equipped with the headrest unit to guide the headrest unit to be switched to a set pillow mode.

First claim

What is claimed is:

1 . A foldable seat apparatus for a multi-purpose vehicle comprising:
a seat unit comprising of a seat cushion, and a seatback rotatably coupled to the seat cushion, and configured to rotate the seatback and formed to make a horizontal state with respect to the seat cushion by operating an operation lever; a headrest unit mounted on the seatback, and provided to be separable; a mounting guide unit coupled to the seat cushion; and a pillow mounting unit configured to be latched to the mounting guide unit to be stored in the seat cushion, drawn out to the outside of the seat cushion by selectively being latch-released from the mounting guide unit in the horizontal state, and equipped with the headrest unit to guide the headrest unit to be switched to a set pillow mode.

2 . The foldable seat apparatus for the multi-purpose vehicle of claim 1 , wherein in the horizontal state, the seat unit is fully flat with respect to the seat cushion.

3 . The foldable seat apparatus for the multi-purpose vehicle of claim 1 ,
wherein the pillow mode is a mode in which the headrest unit is mounted on the pillow mounting unit, and selectively mounted as the seat unit makes the horizontal state so that an occupant's head is supported by the seat cushion.

4 . The foldable seat apparatus for the multi-purpose vehicle of claim 1 ,
wherein the pillow mounting unit comprises: a main body portion movably coupled to a pair of connecting portions provided in the mounting guide unit stored inside the seat cushion; a slide lever portion rail-coupled to the main body portion, and formed to slide inside the main body portion; a locking portion positioned to be latched to a latching groove provided in the mounting guide unit, and formed to be selectively rotated as the slide lever portion slides and is pressurized and latch-released from the latching groove; and a mounting portion provided to be exposed to the outside as the main body portion moves to be drawn out from the seat cushion, and configured to guide the coupling of the headrest unit for a switch to the pillow mode.

5 . The foldable seat apparatus for the multi-purpose vehicle of claim 4 ,
wherein the main body portion is adjustable in position in forward and backward directions of the headrest unit by adjusting a drawn-out position when drawn out from the inside of the seat cushion.

6 . The foldable seat apparatus for the multi-purpose vehicle of claim 4 ,
wherein the main body portion comprises: a base member comprising a pair of coupling areas for coupling the mounting portion; a cover member comprising a through hole coupled to the base member, and formed to face any one of the pair of coupling areas; and an operation member exposed to the outside in a state of being disposed to come into contact with one side of the slide lever portion, and configured to rotate axially according to a pulling operation to selectively pressurize the slide lever portion, and latch-release the locking portion.

7 . The foldable seat apparatus for the multi-purpose vehicle of claim 6 ,
wherein the main body portion further comprises a push button that is inserted into the through hole, and pressurizes a release button provided on the mounting portion to be formed so that a height of the headrest unit is adjustable and removable.

8 . The foldable seat apparatus for the multi-purpose vehicle of claim 7 , wherein the push button faces the release button.

9 . The foldable seat apparatus for the multi-purpose vehicle of claim 1 ,
wherein the headrest unit comprises: a head portion composed of a first area supporting an occupant's head in a state of being mounted on the seatback and a second area positioned above the first area; and a coupling portion provided on a lower portion of the head portion facing the second area, and mounted on the seatback or the pillow mounting unit and formed so that the head portion is fixed thereto.

10 . The foldable seat apparatus for the multi-purpose vehicle of claim 9 , wherein the coupling portion comprises an adjustment groove.

11 . The foldable seat apparatus for the multi-purpose vehicle of claim 10 , wherein the coupling portion comprises a plurality of adjustment grooves, and a height of the head portion is adjusted by an interval between the adjustment grooves.

12 . The foldable seat apparatus for the multi-purpose vehicle of claim 10 , wherein the pillow mounting unit further comprises a guide lock that latch-releases the adjustment groove.

13 . The foldable seat apparatus for the multi-purpose vehicle of claim 12 ,
wherein the head portion is formed so that the first area supports the occupant's head when the head portion is mounted on the seatback, and the second area supports the occupant's head in the pillow mode when the head portion is mounted on the pillow mounting unit.

14 . The foldable seat apparatus for the multi-purpose vehicle of claim 1 ,
wherein the mounting guide unit comprises: a coupling plate comprising a pair of latching grooves having edges coupled and fixed to a center pipe and a main pipe configuring the seat cushion, and formed to be spaced apart from each other in a drawn-out direction of the pillow mounting unit; and a plurality of compression springs coupled to the coupling plate, and configured to selectively provide an elastic force toward the pillow mounting unit that is drawn out.

15 . The foldable seat apparatus for the multi-purpose vehicle of claim 14 , wherein the compression springs are coupled to a mounting groove provided on the coupling plate.

16 . The foldable seat apparatus for the multi-purpose vehicle of claim 14 , wherein the compression springs are configured to elastically pressurize a push fin protruding from the main body portion.

17 . The foldable seat apparatus for the multi-purpose vehicle of claim 14 ,
wherein the mounting guide unit further comprises a stopper provided on the coupling plate, and formed to limit a drawn-out position of the pillow mounting unit in the drawn-out direction, and the stopper is positioned inside each of a pair of slot holes provided in the pillow mounting unit.

18 . The foldable seat apparatus for the multi-purpose vehicle of claim 17 ,
wherein the pillow mode is set so that the pillow mounting unit is positioned to be latched to the latching groove positioned at a front side among the pair of latching grooves and the stopper is positioned to be latched to one end of the slot hole.

19 . A vehicle comprising the foldable seat apparatus for the multi-purpose vehicle of claim 1 .
