The cable 20 is provided to fix a base cover 10 described later to the seat back frame 1. The cable 20 includes a bent portion 21 bent in a U-shape when seen from the front in the center, and a pair of connecting portions 22 connecting an upper end portion 21a of the bent portion 21 and the longitudinal frame 4 a. The bending portion 21 has a pair of first portions 23 extending downward, and a second portion 24 extending in the left-right direction at the lower end thereof and connecting the pair of first portions.

As shown in fig. 2, the seat back frame 1 is provided with a pressure receiving member 70 constituted by an S spring. The pressure receiving member 70 supports the waist of the passenger from the rear. The cable 20 and the base cover 10 are disposed above the pressure receiving member 70.

As shown in fig. 1, the vehicle seat 100 according to the present embodiment is provided with a lighting device 50 on the upper side of the back surface of the seat back 1. The lighting device 50 is used to illuminate the underfoot of the rear seat occupant. A base cover 10 and a panel 30 for fixing the illumination device 50 to the back surface of the seat back S1 are provided.

As shown in fig. 2, the base cover 10 includes a cover main body 15, a pair of left-right direction cable fixing portions 11, a pair of up-down direction cable fixing portions 12, and a pair of lower claw portions 14, 14 for attaching the cover main body 15 to the cable 20.

The cover main body 15 is formed to cover a part of the back surface of the seat back, and a lighting fitting 51 is mounted therein to function as the lighting device 50.

As shown in fig. 2 and 3, the pair of left-right cable fixing portions 11, 11 extend forward from the cover main body 15, and the distal ends 11a, 11a hold the connection portions 22, 22 of the cable 20.

As shown in fig. 2 and 4, a pair of vertical cable fixing portions 12, 12 extend forward from the cover main body 15, and the distal ends 12a, 12a hold the first portions 23, 23 of the cable 20.

As shown in fig. 5, the vertical cable fixing portion 12 includes a pair of right-left direction regulating portions 13, 13 which are provided at positions adjacent to the first portions 23, 23 in the inner direction of the bent portion 21 and regulate the movement of the base cover 10 in the right-left direction. The left-right direction regulating portions 13, 13 regulate movement in the left-right direction by abutting against the first portions 23, 23 of the cable 20.

As shown in fig. 2 and 6, the pair of lower claw portions 14, 14 extend forward from the cover main body 15, and the tip ends are locked to the second portion 24 in the vicinity of the bent portions 23a, 23a located below the bent portion 21.

When the base cover 10 is attached to the longitudinal frame 4a, the lower claw portions 14, 14 extending forward from the cover main body 15 are hung on the second portion 24 near the bent portions 23a, 23a of the cable 20. Accordingly, temporary positioning in the left-right direction is achieved. The base cover 10 is rotated while being suspended from the second portion 24, the distal ends 12a, 12a of the vertical cable fixing portions 12, 12 are attached to the first portions 23, 23 of the cable 20, and the horizontal cable fixing portions 11, 11 are attached to the connecting portions 22, 22 of the cable 20. By the right-left direction regulating portions 13, 13 of the up-down direction cable fixing portions 12, 12 being brought into contact with the cable 20, the right-left direction of the base cover 10 is regulated.

As shown in fig. 2, the left-right direction cable fixing portions 11, 11 are disposed closer to the longitudinal frame 4a than the up-down direction cable fixing portions 12, 12 and the lower claw portions 14, 14. By constituting in this way, the mounting rigidity is improved.

As shown in fig. 2, the pair of lower claw portions 14, 14 are disposed further outside than the center positions of the headrest guide holding portions 6. Accordingly, even when the headrest stay S3c is inserted into the headrest guide holder portion 6 and extends downward, interference with the lower claw portions 14, 14 can be avoided.

In the present embodiment, as shown in fig. 2, the left-right direction regulating portions 13, 13 are disposed between the vertical cable fixing portions 12, 12 and the lower claw portions 14, 14 in the height direction. By arranging in this manner, when the base cover 10 is mounted, the lower claws 14 and 14 temporarily position in the left-right direction, and the left-right direction cable fixing portions 13 and 13 are brought into contact with the cable 20 by rotating about the lower claws 14 and 14, so that the position of the base cover 10 in the left-right direction is corrected, and the base cover 10 can be fixed by the up-down direction cable fixing portions 12 and 12.

The claw portions 11b, 11b of the connecting portion 22 holding the cable 20 at the distal end 11a of the left-right direction cable fixing portion 11 are formed so as to be less likely to bend than the claw portions 12b, 12b of the first portion 23 held by the distal end 12a of the up-down direction cable fixing portion 12.

The claw portions 11b, 11b of the connecting portion 22 holding the cable 20 at the distal end 11a of the left-right direction cable fixing portion 11 are set to insert a load larger than the claw portions 12b, 12b holding the first portion 23 at the distal end 12a of the up-down direction cable fixing portion 12.

By providing the left-right direction cable fixing portion 11 in this manner, the portions (the claw portions 11b, 11 b) where the large insertion load is provided are disposed in the vicinity of the longitudinal frame 4a, and therefore stable mounting of the base cover 10 is enabled.

Next, a structure in which the panel 30 is attached to the base cover 10 will be described. The panel 30 is a plate-like member attached to the back surface of the base cover 10.

A plurality of panel fixing portions 19 are provided for attaching the panel 30 to the base cover 10. As shown in fig. 3 and 8, as the panel fixing portion 19, a plurality of clips 191 (upper fixing portion) provided on the upper side of the panel 30 are attached to the base cover 10 of the present embodiment, and a plurality of lower claw portions 192 (lower fixing portion) are provided on the lower side of the panel 30. The clip 191 provided on the upper side of the panel 30 uses a metal SK clip. However, the clip 191 is not limited to the SK clip, and may be a resin clip.

The clip 191 extends rearward from the cover body 15, and the tip of the clip 191 is inserted into the hole 37 (see fig. 3) provided in the rear surface of the panel 30. The base cover 10 is provided with 4 clips 191, and 4 holes 37 of the panel 30 are formed corresponding to the positions of the clips 191. The clip 191 is the metal SK clip described above, and a base for attaching the clip 191 as the SK clip is provided on the base cover 10.

The base cover 10 has a groove 164 formed along the lower end of the panel 30, and an insertion piece 32 formed along the lower end and extending forward is provided at the lower end of the panel 30. The groove 164 of the base cover 10 is formed corresponding to the shape of the lower end of the panel 30. The lower claw portion 192 has a lower claw portion 192U having a U-shaped cross section and a lower claw portion 192J having a J-shaped cross section. As shown in fig. 11, the lower surface of the lower claw portion 192J contacts the lower end portion of the panel 30. When the insert piece 32 is simultaneously inserted into the skin S1b and the groove 164, the insert piece 32 is pressed by the lower claw portion 192J, and the insert piece 32 is fixed.

As shown in fig. 8, the positions of the plurality of clips 191 in the left-right direction are arranged so as not to overlap with the positions of the plurality of lower claw portions 192J, 192U in the left-right direction in the up-down direction. By being arranged in a staggered manner in the left-right direction, the space efficiency in the up-down direction is improved.

Further, since the lower end portion of the panel 30 is fixed by the lower claw portion 192J and the lower claw portion 192U having the J-shape in the inner cross section of the groove portion, the claw portion is fixed while restricting in the up-down direction, and stable fixation can be performed.

The rear surface of the panel 30 is fixed by the plurality of clips 191, and the lower end portion (the insertion piece 32) of the panel 30 is fixed by the groove 164 and the lower claw portions 192J, 192U of the base cover 10, whereby stable attachment is enabled.

Skin mounting structure.

Next, a structure in which the skin S1b is attached to the base cover 10 will be described.

As described above, the seat frame 101 includes the cushion S1a that wraps the seat frame 101, and the skin S1b that covers the seat frame 101 and the cushion S1 a. In the seat 100 for a vehicle according to the present embodiment, the cushion S1a covering the base cover 10 and the skin S1b covering the cushion S1a are attached to the surface of the base cover 10, except for the portion to which the panel 30 is attached. A skin locking portion 16 for locking the skin S1b is provided around the portion of the base cover 10 to which the panel 30 is attached. The decorative string 40 at the rear end of the skin S1b is locked to the skin locking portion 16, and the panel 30 is fixed to the base cover 10 such that the end of the panel 30 overlaps the decorative string 40 of the skin S1b in the front-rear direction.

Specifically, as shown in fig. 9 and 10, the base cover 10 has an upper-side skin locking portion 161 as a skin locking portion 16 which is disposed above the base cover 10 and locks the skin. A first guide 17 (see fig. 8) disposed in the center of the base cover 10 and second guide 18 disposed on the right and left sides of the first guide 17 are provided on the opposite surface facing the upper surface locking portion 161. The first guide portion guides the decorative string 40 of the skin S1b to the upper skin engaging portion 161 using a wall surface, and the second guide portion 18 guides the decorative string 40 of the skin S1b to the upper skin engaging portion 161 using a rib. The first guide 17 and the second guide 18 guide the decorative rope 40 downward of the upper skin engaging portion 161, whereby the skin S1b is engaged with the upper skin engaging portion 161.

The base cover 10 further includes side skin locking portions 162 as skin locking portions 16 which are disposed on the left and right sides of the base cover 10 and lock the skin. The side skin locking portion 162 is disposed such that the distal end portion 162a of the side skin locking portion 162 faces the center of the base cover 10 (see fig. 8 and 12).

A through hole 41 is formed in the decorative string 40 at a position corresponding to the distal end portion 162a of the side skin locking portion 162, and the decorative string 40 can be locked to the side skin locking portion 162 by inserting the distal end portion 162a into the through hole 41.

The lower claw portion 192 of the insertion piece 32 for fixing the lower end portion of the panel 30 and the lateral skin locking portion 162 of the base cover 10 are disposed at positions overlapping each other in the height direction. Accordingly, the rigidity of the side skin engaging portion 162 is improved.

The insertion piece 32 of the panel 30 is overlapped with the decorative string 40 and inserted into the groove 164 of the base cover 10, thereby fixing the panel 30. By overlapping and inserting the insertion piece 32 and the decorative string 40, the decorative string 40 is less likely to separate from the groove 164, and the skin S1b can be firmly fixed. Since it is not necessary to use a separate member to fix the skin S1b, the structure for preventing the skin S1b from being detached can be miniaturized.

An illumination device.

As shown in fig. 1, the vehicle seat 100 of the present embodiment is provided with a lighting device 50 on the back surface of a seat back S1. In the following description, the lighting device 50 will be described with reference to fig. 1 and 14 to 16. As shown in fig. 1, the lighting device 50 is a lighting device that illuminates the underfoot of the rear seat occupant. As shown in fig. 14, the illumination device 50 includes the seat back frame 1, the base cover 10 attached to the seat back frame 1, the panel 30 (see fig. 16) attached to the base cover 10, and the illumination fitting 51 attached to the base cover 10.

As shown in fig. 14, the base cover 10 is provided with a flat plate-like support portion 64 for mounting the lighting fixture 51, and the lighting fixture 51 is held by an LED holding portion 63 standing from the support portion 64. As shown in fig. 15, the lighting fixture 51 is attached to the support 64 from above. By mounting the illumination fitting 51 from above the base cover 10, it is possible to suppress lens scratches of the illumination fitting 51 as compared with a case of mounting from the lateral direction or the front-rear direction.

The support portion 64 includes a harness holding portion 61 that holds the harness 60 extending from the lighting fitting 51, and a harness fixing portion 62 that fixes the harness held by the harness holding portion 61. The harness holding portion 61 is provided above the LED holding portion 63, and thus, an extra length of the harness can be held, and the assembling workability can be improved.

An illumination hole 52 through which light illuminated by the illumination fitting 51 passes is formed below the illumination fitting 51 mounted on the base cover 10. The light emission hole 52 is formed by a first opening 53 formed in the base cover 10 and a second opening 54 formed in the panel 30. The second opening 54 is formed at a position opposite to the first opening 53 in a state where the panel 30 is mounted on the base cover 10. As shown in fig. 16, the second opening 54 is disposed at a position offset rearward by a predetermined distance with respect to the first opening 53.

As shown in fig. 1, the seat back frame 1 is covered with a cushion S1a, and the seat back frame 1 and the cushion S1a are covered with a skin S1 b.

As shown in fig. 16, the first opening 53 and the second opening 54 are disposed below the first opening 53 and the second opening 54 and behind the skin S1b covering the back surface of the base cover 10. By setting the illumination of the illumination device behind the skin S1b, for example, the light irradiated to the skin S1b is not suppressed, and thus the underfoot of the rear seat passenger can be properly illuminated.

The first opening 53 and the second opening 54 are disposed above the pressure receiving member 70 (see fig. 2) disposed in the center of the seat back S1. By disposing the light emission hole 52 of the illumination device 50 above the pressure receiving member 70, for example, even when the passenger receives a forward load and the pressure receiving member moves backward, the illumination device is less likely to be affected.

As shown in fig. 16, a wall portion 55 formed to extend in the up-down direction is provided on the panel 30 around the second opening 54. By providing the wall portion 55, it is possible to easily set the distance between the first opening 53 and the second opening 54 while suppressing light from leaking between the first opening 53 and the second opening 54.

The wall portion 55 is constituted by a front side wall portion 551 located on the front side of the second opening portion 54, and a rear side wall portion 552 located on the rear side. As shown in fig. 16, the wall 55 is formed such that the upper end 551a of the front side wall 551 is positioned higher than the upper end 552a of the rear side wall 552. By changing the heights of the front side wall portion 551 and the rear side wall portion 552, the occurrence of noise due to the contact of the first opening portion 53 with the entire upper surface of the wall portion 55 is suppressed.

A gap 56 of a specific distance L3 is provided between the rear sidewall 552 of the second opening 54 and the lower surface of the base cover 10 (the lower surface around the first opening 53). The provision of the void 56 can suppress noise generation caused by contact between the periphery of the first opening 53 of the base cover 10 and the rear wall 552 of the second opening 54 of the panel 30.

Further, the lower surface portion 30a and the rear surface portion 30b of the panel 30 are formed from below the space 56 to the rear so as to cover the space 56. Since the lower surface portion 30a and the rear surface portion 30b of the panel 30 covering the void 56 are formed, light leaking from the void is blocked by the lower surface portion 30a and the rear surface portion 30b, and light leakage can be prevented.

Further, a slope portion 57 inclined downward and rearward from the rear of the periphery of the second opening 54 is provided. In other words, the lower surface portion 30a of the panel 30 is inclined downward. By providing the inclined surface portion 57, the backward light of the light emitted from the second opening 54 can be directed downward, and indirect illumination can be set.

The lighting fixture 51 includes an LED58 (LIGHT EMITTING Diode) and a lens 59 (light guide) for guiding light emitted from the LED58 in the lighting fixture 51, and as shown in fig. 16, the lens 59 is disposed so as to be positioned below the LED58 when the lighting fixture 51 is mounted on the base cover 10. At least a part of the lens 59 is disposed at a position overlapping the first opening 53 in the height direction.

By disposing the lens 59 at a position overlapping the first opening 53 in the height direction, miniaturization in the height direction can be achieved, and by eliminating the gap between the illumination fitting 51 and the first opening 53, the amount of light leakage can be suppressed.

The diameter L1 of the first opening 53 is set to be larger than the diameter L2 of the second opening 54. By setting the diameter L1 to be larger than the diameter L2, the irradiation range of light from the first opening 53 can be easily set to be reduced by the second opening 54.

The embodiments of the present application are described above with reference to the drawings. In the above-described embodiment, the vehicle seat mounted on the vehicle has been described as a specific example, but the vehicle seat is not limited to the vehicle, and the vehicle seat of the present application may be provided as a seat of a train, an automobile, or the like, or may be provided as a seat of an aircraft, a ship, or the like.
