[0043] In addition, the seat back (20) may include a bolster (230) that is detachably installed with the back frame (200) at a position corresponding to the arm portion of the human body. The bolster (230) may be fixed to the back frame (200) through a magnet inserted into the inside of the bolster (230), and although not shown in the drawing, it is also possible to firmly fix it using a screw-type bolt.

[0044] In addition, the back frame (200) may be formed as a hollow frame structure overall so that air can flow inside, and at least one back air vent (202) may be formed so that air can be sprayed in a direction toward the passenger's upper body. The back air vent (202) may be installed at a location corresponding to the shoulder or waist area of ​​the human body.

[0045] In addition, as illustrated in FIG. 5, the seat back (20) may include a headrest (240) that is detachably installed with the back frame (200) at a position corresponding to the head of the human body.

[0046] The headrest (240) is composed of a lower frame (241), an upper frame (242) coupled to the lower frame (241), and a mesh fabric (243) coupled to the upper frame (242), and can be coupled to the headrest mounting portion (203) of the back frame (200). At this time, the headrest mounting portion (203) can rotate left and right, so that the headrest (240) can rotate left and right on the back frame (200).

[0047] In addition, as illustrated in FIG. 6, the seat back (20) may include a map pocket (250) that is detachably installed at the rear of the back frame (200). The map pocket (250) may include a plate-shaped support member (251) and at least one band (252) that is fixed to extend in the area direction of the support member (251).

[0048] Accordingly, passengers can customize the seat by easily replacing the bands (252) of various colors and store various items in the space between the support member (251) and the band (252).

[0049] In addition, as shown in FIGS. 7 and 8, the seat cushion (20) may include a cushion assembly (110) that is detachably installed with the cushion frame (100) at a position corresponding to the hip area of ​​the human body.

[0050] More specifically, the cushion assembly (110) may have a cushion-side heating wire (112) or a cushion-side air vent (111) formed in an area corresponding to the buttocks of the human body so as to perform a heating or ventilation function. The cushion-side air vent (111) may have a type of manifold shape and may discharge air drawn in from the inlet side to multiple outlet sides facing the outside of the cushion.

[0051] In addition, although not shown in the drawing, the cushion assembly (110) may include a covering that is formed in a shape corresponding to the outer surface and is installed to be detachable while surrounding the cushion assembly (110). The covering can be easily attached to and detached from the cushion assembly (110) using a structure such as a zipper or button.

[0052] In addition, the cushion assembly (110) may be composed of a plurality of types of pads having an appropriate shape or appropriate density and hardness according to the passenger's preference, and coverings of various colors and textures. For example, it may be composed of a soft type pad having a density of 50 kg / m3 and a hardness of 15 kgf, a normal type pad having a density of 50 kg / m3 and a hardness of 30 kgf, a hard type pad having a density of 50 kg / m3 and a hardness of 45 kgf, etc., and a pad that suits the passenger's preference among various types of pads with different heights of the bolster surface or flatness of the seating area that the buttocks of the human body touches can be selected and applied to the seat.

[0053] At this time, the cushion frame (100) may include a second cushion air vent (102) formed at a position corresponding to the inlet side of the cushion-side air vent (111) of the cushion assembly (110). Accordingly, air may be introduced from a separately installed blower through the flow path (120) and supplied to the pad-side air vent flow path (111) of the cushion assembly (110) to perform a ventilation function.

[0054] In addition, the cushion frame (100) may be formed as a hollow frame structure overall so that air can flow inside, and a first cushion air outlet (101) may be formed at a connection portion with the back frame (200) so that air can be sprayed in a direction toward the passenger's waist.

[0055] Therefore, the ventilation function can be performed more effectively on the passenger's back through the triangular ventilation structure formed by the back air vent (202) of the back frame (200) and the first cushion air vent (101) of the cushion frame (100).

[0056] The back vent (202) and the first cushion vent (101) can be supplied with cold air or hot air through separate blowers, or cold air or hot air can be supplied to all of the back vent (202), the first cushion vent (101), and the second cushion vent (102) using one integrated blower to provide ventilation or warm air to passengers.

[0057] In addition, the cushion frame (100) may include a front cushion insertion hole (103) and a rear cushion insertion hole (104), and the cushion assembly (110) may include a front cushion insertion protrusion (113) and a rear cushion insertion protrusion (114) formed at positions corresponding to the front cushion insertion hole (103) and the rear cushion insertion hole (104).

[0058] The front cushion insertion protrusion (113) can be formed with a glommet assembly structure, and the rear cushion insertion protrusion (114) can be formed with a hook assembly structure so that passengers can conveniently attach and detach the cushion assembly (110) to the cushion frame (100).

[0059] Additionally, as illustrated in FIG. 9, the seat cushion (10) may include a floor (130) that is combined with a cushion frame (100) to support the foot portion of the human body.

[0060] More specifically, the floor (130) may have a floor-side heating wire (132) installed in an area corresponding to the foot of the human body, or a floor-side air vent (131) formed therein, so as to perform a heating or ventilation function. The floor-side air vent (131) may also be supplied with cold air or hot air through a separate blower, or the aforementioned integrated blower may be used to supply cold air or hot air to all of the back air vent (202), the first cushion air vent (101), the second cushion air vent (102), and the floor-side air vent (131), so as to perform a ventilation or heating function for passengers.
