[0035] FIGS. 1A, 1B, 2, and 3 illustrate a ventilation and heating apparatus for a child seat according to the present disclosure. In each drawing, reference numeral 10 denotes a seat body of the child seat.

[0036] The seat body 10 may be injection-molded using a plastic material in a shape that allows a child to sit thereon, and a cover plate 11 that is separately manufactured may be mounted on a rear surface of the seat body.

[0037] A ventilation mat 40 which is made of a ventilatable material and in which heating wire is embedded is attached to a front sitting portion of the seat body 10.

[0038] Particularly, as illustrated in FIG. 4, the ventilation mat 40 may include a breathable mesh material layer 41 of a predetermined thickness, a heating wire 42 embedded in a front side of the mesh material layer 41 in a predetermined arrangement, and a vinyl layer 43 coated on a surface of the mesh material layer 41 to block air flowing to the mesh material layer 41 from escaping to an outside.

[0039] Here, a plurality of air discharge holes 44 is formed through the vinyl layer 43 coated on the front portion of the mesh material layer 41, so air flowing in the mesh material layer 41 may be intensively discharged through the air discharge hole 44.

[0040] Preferably, the ventilation mat 40 is formed by integrating a back pad 40-1 with which a child's upper body is in close contact and a cushion pad 40-2 with which a child's lower body is in close contact. A buckle-avoiding cutout 46 is concavely formed in a front end of the cushion pad 40-2 of the ventilation mat 40 to avoid interference with a buckle of the child seat.

[0041] Thus, the buckle for fastening a 5-point belt for the child seat is mounted at a central position on the front end of the seat body 10. Since the buckle may be easily exposed through the buckle-avoiding cutout 46 of the cushion pad 40-2 of the ventilation mat 40, a tongue of the 5-point belt of the child seat may be easily fastened to the buckle.

[0042] A ventilation blower 20 for supplying ventilation air to the ventilation mat 40 is mounted in a back portion of the seat body 10.

[0043] Preferably, the ventilation blower 20 is fixedly mounted on a frame 12 installed in the seat body 10.

[0044] For example, in a state where the cover plate 11 mounted on the rear portion of the seat body is opened, the ventilation blower 20 may be introduced into the seat body 10, and then the frame 12 may be mounted on the ventilation blower 20.

[0045] At this time, a duct support hole 14 through which a duct 30 connected to a discharge part of the ventilation blower 20 passes is formed in a predetermined position on the front portion of the seat body 10.

[0046] Further, a duct fastening groove 45 to which the front end of the duct 30 is fastened is formed in the rear portion of the ventilation mat 40.

[0047] Thus, after the duct 30 connected to the discharge part of the ventilation blower 20 passes through the duct support hole 14 of the seat body 10, the front end of the passing duct 30 is air-tightly inserted and fastened to the duct fastening groove 45 formed in the rear portion of the ventilation mat 40, so blowing air caused by the driving of the ventilation blower 20 may be easily supplied along the duct 30 to the ventilation mat 40.

[0048] A base plate 50 which is configured to be seated on the rear seat and to make the inside of the seat body 10 and outdoor air communicate with each other is mounted on the bottom of the seat body 10.

[0049] In detail, the base plate 50 has an opening formed thereon to mount mechanism components for swiveling and reclining the seat body 10. Further, the bottom of the base plate 50 is formed as a flat surface to be seated on the rear seat, and a grill 52 is formed on a side of the base plate to draw outdoor air.

[0050] Further, an opening is formed on the bottom of the seat body 10 to mount mechanism components for swiveling and reclining, thus allowing the interior of the base plate 50 to communicate with the interior of the seat body 10.

[0051] Thus, when the ventilation blower 20 is driven, outdoor air is sucked through the grill 52 of the base plate 50 to easily flow to an intake side of the ventilation blower 20 in the seat body 10, thus allowing the air intake and blowing operation of the ventilation blower 20 to be efficiently performed.

[0052] A connector 54 connected to a power supply so as to supply power to the heating wire 42 and the ventilation blower 20 is mounted on the rear end of the base plate 50. Further, although a switch for turning on and off the heating wire 42 and the ventilation blower 20 is not shown, the switch may be installed at a predetermined position of the child seat.

[0053] Here, the operation flow for the ventilation and heating apparatus for the child seat according to the present disclosure configured as described above is as follows.

[0054] FIG. 5 is a perspective view illustrating a state in which the child seat having the ventilation and heating apparatus according to the present disclosure is seated on the rear seat for the vehicle, and FIG. 6 is a sectional view illustrating the operating state of the ventilation and heating apparatus for the child seat according to the present disclosure.

[0055] The child seat having the ventilation and heating apparatus according to the present disclosure is fixedly seated on the rear seat of the vehicle.

[0056] In other words, when the base plate 50 is seated and fixed on the rear seat, the seat body 10 is disposed in a state where a child may sit.

[0057] When the child sits on the seat body 10, the child's upper body may be in close contact with the back pad 40-1 of the ventilation mat 40, and the child's lower body may be in close contact with the cushion pad 40-2 of the ventilation mat 40.

[0058] In this case, in summer, the child may feel hot or feel discomfort such as sweating due to a long ride.

[0059] In order to solve this problem, the ventilation blower 20 in the seat body 10 is driven. Then, outdoor air is sucked through the grill 52 of the base plate 50 and flows to the intake side of the ventilation blower 20, and the sucked air is blown to the ventilation mat 40 through the discharge part of the ventilation blower 20.

[0060] In more detail, after the blowing air generated by the driving of the ventilation blower 20 is supplied and diffused to the mesh material layer 41 of the ventilation mat 40 along the duct 30, the air flowing in the mesh material layer 41 may be intensively discharged through a plurality of air discharge holes 44 formed in the vinyl layer 43.

[0061] At this time, the blowing air flowing to the mesh material layer 41 is not discharged to the outside by the vinyl layer 43, but is intensively discharged through the plurality of air discharge holes 44 formed in the vinyl layer 43, thus allowing the ventilation air to intensively act on the child's body.

[0062] As such, in summer or when ventilation is required, ventilation air is discharged toward a child's body through the ventilation mat 40, thus resolving discomfort such as sweating or feeling hot and thereby providing a pleasant seating environment for the child.

[0063] In winter, a child sitting on the child seat may feel cold.

[0064] In order to solve this problem, the heating wire 42 embedded in the ventilation mat 40 may be driven, so it is possible to resolve the discomfort of the child sitting on the child seat, such as feeling cold, thus providing a comfortable seating environment for the child.

[0065] Although the present disclosure was described with reference to specific embodiments shown in the drawings, it is apparent to those skilled in the art that the present disclosure may be changed and modified in various ways without departing from the scope of the present disclosure, which is described in the following claims.
