[0054] The first lower rail section (50) and the second lower rail section (52) are distinguished for ease of understanding, and their configurations are identical, but there is a difference in their shape and mounting position.

[0055] A seat rail system (10) according to an embodiment of the present invention may include a brush assembly (90) comprising a brush (92) that is mounted on each of the first upper rail portion (82) and the second upper rail portion (84) and contacts the busbar (60).

[0056] The poles of the power supplied to the busbar (60) mounted on the first lower rail section (50) and the second lower rail section (52), respectively, may be different from each other.

[0057] In FIG. 1, the power supplied to the busbar (60) mounted on the first lower rail section (50) is shown as a positive pole, and the power supplied to the busbar (60) mounted on the second lower rail section (52) is shown as a negative pole, but this is not limited thereto, and it is also possible to supply power in the opposite direction.

[0058] Generally, bus bars are in the form of metal strips or rods and have sufficient rigidity.

[0059] Accordingly, the busbar (60) is applied to the first lower rail section (50) and the second lower rail section (52) where the seat assembly (190) moves, thereby preventing deformation or damage and enabling a stable power supply.

[0060] The insulator (70) can wrap around the busbar (60) to block electric leakage to the lower rail (20).

[0061] The first lower rail section (50) and the second lower rail section (52) may include at least one curved section (32).

[0062] That is, as described in FIG. 1, the rail (12) may include the straight section (30) and the curved section (32), and the seat rail system (10) according to an embodiment of the present invention can stably supply electric power even when the seat assembly (190) moves along the curved section (32).

[0063] FIG. 4 is a perspective view of a brush assembly of a seat rail system according to an embodiment of the present invention, and FIG. 5 is a partial perspective view of a seat rail system according to an embodiment of the present invention.

[0064] FIG. 6 is an exploded perspective view of a slide bushing and a slide housing of a seat rail system according to an embodiment of the present invention, and FIG. 7 and FIG. 8 are partially exploded perspective views of a seat rail system according to an embodiment of the present invention.

[0065] FIG. 9 is an exploded perspective view of a brush assembly of a seat rail system according to an embodiment of the present invention.

[0066] Referring to FIG. 4, the brush (92) can be mounted to be rotatable relative to the brush assembly (90) so as to be in constant contact with the busbar (60). Here, relative rotation refers to a change in position or rotation of the brush (92) relative to the brush assembly (90) so as to be in constant contact with the busbar (60), and this will be explained later.

[0067] The brush (92) may include a front brush (94) mounted so as to be rotatable relative to the brush assembly (90), and a rear brush (96) mounted separately from the front brush (94) so ​​as to be rotatable relative to the brush assembly (90).

[0068] Although the front brush (94) and the rear brush (96) are shown in the drawing, they are not limited thereto, and the brush (92) may be mounted in one or more than two places so as to be rotatable relative to the brush assembly (90).

[0069] Additionally, the front brush (94) and the rear brush (96) are distinguished by name for ease of understanding and are not limited to their direction of movement or mounting position.

[0070] Referring to FIGS. 4 and 9, the brush (92) may include a brush contact portion (98) that contacts the busbar (60), and a brush body (100) supported by a brush elastic portion (130) to ensure the brush contact portion (98) is in close contact with the busbar (60).

[0071] That is, the brush assembly (90) may include a brush bracket (110), a brush case (120) mounted on the brush bracket (110) and to which the brush (92) is mounted so as to be rotatable relative to it, and a brush elastic part (130) that elastically supports the brush (92).

[0072] The brush case (120) can be mounted to the brush bracket (110) through a bracket fastener (132). Additionally, the brush case (120) includes a front case (121) and a rear case (122), and the brush elastic part (130) can be mounted between the front case (121) and the rear case (122).

[0073] The brush elastic member (130) may have various elastic configurations that support the brush (92). For example, the brush elastic member (130) may include at least one compression spring. And, when the seat assembly (190) passes through the curved section (32), the brush elastic member (130) may push the brush (92) toward the busbar (60) to maintain contact between the brush (92) and the busbar (60). Additionally, the brush elastic member (130) may elastically support the brush (92) so that the brush elastic member (130) rotates relative to the brush assembly (90).

[0074] The brush case (120) may have a cable hole (124) through which a cable (140) electrically connected to the brush (92) passes.

[0075] A brush hole (101) is formed in the brush (92), and a cable (140) can be inserted into the brush hole (101).

[0076] The power transmitted to the busbar (60) can be reliably transmitted to the sheet assembly (190) through the brush (92) and the cable (140).

[0077] Referring to FIGS. 2 to 6, a seat rail system (10) according to an embodiment of the present invention may further include a slide rail (40) mounted on the first lower rail section (50) and the second lower rail section (52), respectively, and a slide bush (150) mounted on the brush assembly (90) to move along the slide rail (40).

[0078] The slide bush (150) can move along the slide rail (40) which is mounted on the first lower rail section (50) and the second lower rail section (52), respectively, so that the brush assembly (90) can move stably along the first lower rail section (50) and the second lower rail section (52).

[0079] The brush assembly (90) may further include a slide housing (152) on which the slide bush (150) is mounted. The slide bush (150) may be rotatably mounted within the slide housing (152).

[0080] The slide housing (152) stably supports the slide bush (150) so that even if the brush assembly (90) moves along the first lower rail section (50) and the second lower rail section (52), the brush assembly (90) does not shake, thereby enabling a stable power supply without a short circuit.

[0081] Referring to FIGS. 4 to 8, the brush assembly (90) applicable to the seat rail system (10) according to an embodiment of the present invention may include an upper bracket plate (160) that is rotatably mounted on the upper part of the brush bracket (110).

[0082] A brush assembly hinge hole (162) is formed on the upper part of the brush assembly (90), and a bracket plate hinge hole (161) is formed in the upper bracket plate (160), and a hinge pin (164) is inserted into the brush assembly hinge hole (162) and the bracket plate hinge hole (161) so that relative rotation of the upper bracket plate (160) is possible.

[0083] The brush assembly (90) may further include a brush carrier (170) mounted on the upper bracket plate (160).

[0084] For example, a carrier coupling hole (165) is formed in the upper bracket plate (160), and a carrier fastener (172) is fastened to the carrier coupling hole (165) so that the brush carrier (170) can be mounted on the upper bracket plate (160). The brush carrier (170) can support the seat assembly (190).

[0085] FIG. 10 is a partial cross-sectional view of a seat rail system according to an embodiment of the present invention.

[0086] Referring to FIGS. 2 and FIGS. 10, the insulator (70) may include an insulator elastic part (72) that pushes the busbar (60) in the direction of the brush (92).

[0087] For example, the insulator elastic part (72) is formed of a material with elasticity different from that of the insulator (70) so as to be able to push the busbar (60) toward the brush (92). Additionally, the insulator elastic part (72) may be a single space, or the busbar (60) may be pressed into the insulator (70) to maintain the force of the busbar (60) pushing toward the brush (92).

[0088] For example, an insulator housing (62) may be formed on the brush bracket (110), and the insulator (70) may be inserted into the insulator housing (62). An insulator housing protrusion (64) may be formed on the insulator housing (62), and an insulator protrusion (75) may be formed on the insulator (70) to be pressed in by the insulator housing protrusion (64). Through this configuration, separation between the insulator (70) and the brush bracket (110) can be prevented.

[0089] In addition, an insulator projection (74) that elastically supports the busbar (60) is formed at one end of the insulator (70) to prevent separation between the busbar (60) and the insulator (70).

[0090] FIG. 11 is a drawing illustrating the operation of a seat rail system according to an embodiment of the present invention.

[0091] Referring to FIGS. 1, 10 and 11, the brush elastic part (130) can push the brush (92) toward the busbar (60) to maintain contact between the brush (92) and the busbar (60).

[0092] When the above sheet assembly (190) passes through the curved section (32), the brush elastic part (130) also elastically supports the brush (92), so that the brush elastic part (130) can rotate relative to the brush assembly (90), thereby maintaining contact between the brush (92) and the busbar (60). Additionally, the front brush (94) and the rear brush (96) can be separated and rotated independently, so that contact between the brush (92) and the busbar (60) can be maintained even when the above sheet assembly (190) passes through the curved section (32).

[0093] FIG. 12 is a partial plan view of a seat rail system according to an embodiment of the present invention.

[0094] Referring to FIGS. 2, 4, 8 and 12, a seat rail system (10) according to an embodiment of the present invention may further include a brush connect bracket (180) connecting each of the upper bracket plates (160) on the first upper rail portion (82) and the second upper rail portion (84).

[0095] Each of the above upper bracket plates (160) and the brush connect bracket (180) can be connected so as to allow relative rotation.

[0096] A seat rail system (10) according to an embodiment of the present invention further includes a connecting pin (182) connecting each upper bracket plate (160) and the brush connect bracket (180), and the brush connect bracket (180) may have a fixed hole (184) and an elongated hole (186) into which each connecting pin (182) is inserted.

[0097] A connect bracket connection hole (181) is formed in the upper bracket plate (160), and a connecting pin (182) is inserted into the connect bracket connection hole (181) to connect the upper bracket plate (160) and the brush connect bracket (180).

[0098] The brush connect bracket (180) can connect the upper bracket plates (160) on both sides to prevent the upper bracket plates (160) from tilting.

[0099] Additionally, the hole (184) shown in FIG. 12 can be connected to one, for example, the upper bracket plate (160) on the right side of the drawing, through the connecting pin (182), and the elongated hole (186) can be connected to the other, for example, the upper bracket plate (160) on the left side of the drawing, through the connecting pin (182).

[0100] This configuration stably supports the brush assembly (90) even if there is a distance difference between the first lower rail section (50) and the second lower rail section (52), thereby preventing a short circuit of the power supply and enabling stable movement of the seat assembly (190).

[0101] A seat rail (196) is mounted on the brush carrier (170), and the seat assembly (190) can be coupled to the seat rail (196).

[0102] As explained above, according to the seat rail system of the embodiment of the present invention, integrated wiring is not applied and separate busbars are applied, thereby suppressing the occurrence of problems such as injury or disconnection caused by the exposure of wiring.

[0103] In addition, according to the seat rail system of the embodiment of the present invention, integrated wiring is not applied, so the stroke is not limited.

[0104] According to the seat rail system of the embodiment of the present invention, a chain for wiring protection is not applied, so the weight of the vehicle can be reduced and the production cost can be lowered.

[0105] According to the seat rail system of the embodiment of the present invention, contact between the busbar and the brush is maintained, so power can be supplied stably and safely.

[0106] In addition, according to the sheet rail system of the embodiment of the present invention, power can be supplied stably and safely even on a rail that includes a curved section.

[0107] Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and includes all modifications within the scope recognized as equivalent that can be easily made by those skilled in the art from the embodiments of the present invention.
