Description

Technical Field

[0001] The present invention relates to a seat for a vehicle to be mounted on a vehicle, and in particular to a seat for a vehicle having a base cover covered with a skin on the back side. Background Art

[0002] In the fixing structure of the end of the skin, the structure of inserting the decorative rope into the groove for fixing is well known. For example, there is an automotive interior decoration accessory described in Patent Document 1. In the automotive interior decoration accessory of Patent Document 1, a dividing line is set on the skin to divide the product surface into multiple areas, and a fitting groove is formed along the dividing line. The skin is sealed by pressing and fixing the insertion leg of the clip strip in the fitting groove. Patent Document 1: Japanese Patent Publication No. 2005-53435 Summary of the invention

[0003] However, in the case of a conventional decorative cord that fixes the end of the surface, there is a problem that the cord becomes larger due to the formation of the insertion portion.

[0004] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a seat for a vehicle having a structure for preventing the skin from falling off without increasing the size of the decorative cord.

[0005] The above-mentioned problem is solved by the following method. A passenger seat comprises a seat frame, a cushion wrapping the seat frame, and a skin covering the seat frame and the cushion, a base cover mounted on the back of the seat frame and having a skin locking portion for locking the skin, and a panel fixed to the base cover, wherein a skin fixing portion at the back side end of the skin is locked to the skin locking portion, and the panel is fixed to the base cover in a manner that the end of the panel and the skin fixing portion overlap in the front-rear direction.

[0006] Since the end of the panel is fixed to the base cover so as to overlap with the surface fixing portion (decorative string) in the front-rear direction, it is possible to suppress the surface fixing portion from coming off.

[0007] In the above-mentioned passenger seat, it is preferred that the base cover has an upper skin locking portion which is arranged on the upper side of the base cover and locks the skin as the skin locking portion, and the opposite surface of the upper skin locking portion has a first guide portion arranged in the center of the base cover and a second guide portion arranged on the right and left sides of the first guide portion, and the skin fixing portion is guided by the first guide portion and the second guide portion and locked by the upper skin locking portion.

[0008] Since the skin fixing portion is guided by the central first guide portion and the second guide portions arranged on the right and left sides of the first guide portion, the skin fixing portion can be easily locked.

[0009] In the above-mentioned passenger seat, it is preferred that the base cover has a side skin locking portion as the skin locking portion, which is arranged on the left or right side of the base cover and locks the skin, and the side skin locking portion is arranged in such a way that the top end of the side skin locking portion faces the center of the base cover, and the skin fixing portion is formed with a hole at a position corresponding to the top end of the side skin locking portion, and the skin fixing portion is locked by inserting the top end into the hole.

[0010] By inserting the hole of the epidermis fixing portion into the tip end portion of the side epidermis locking portion, the epidermis fixing portion can be stabilized and fixed.

[0011] In the above-mentioned passenger seat, it is preferred that the base cover has a lower fixing portion arranged on the lower side of the base cover as a panel fixing portion for fixing the panel, and a portion of the lower fixing portion is arranged on the left or right side of the base cover at a position overlapping with the side skin locking portion in the height direction.

[0012] By arranging the side skin locking portion and the lower fixing portion at a position where they overlap in the height direction, the rigidity of the mounting portion of the base cover can be increased.

[0013] In the above-mentioned passenger seat, it is preferred that the base cover has a groove as the skin locking portion, the skin fixing portion of the skin is arranged on the bottom side of the groove, and the lower end of the panel is arranged at a position overlapping with the skin fixing portion in the groove.

[0014] Since the lower end of the panel and the skin fixing portion overlap in the groove portion, it is possible to more firmly suppress the skin fixing portion from falling off.

[0015] Since the end of the panel is fixed to the base cover so as to overlap with the surface fixing portion (decorative string) in the front-rear direction, it is possible to suppress the surface fixing portion from coming off.

[0016] In addition, since the skin fixing portion is guided by the central first guide portion and the second guide portions arranged on the right and left sides of the first guide portion, the skin fixing portion can be easily locked.

[0017] In addition, by inserting the hole of the epidermis fixing portion into the tip end portion of the side epidermis locking portion, the epidermis fixing portion can be stabilized and fixed.

[0018] Furthermore, by arranging the side skin locking portion and the lower fixing portion at a position where they overlap in the height direction, the rigidity of the mounting portion of the base cover can be increased.

[0019] Since the lower end of the panel and the skin fixing portion overlap in the groove portion, it is possible to more firmly suppress the skin fixing portion from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

Regarding the configurations of a pair of left and right settings, they are marked with common numbers, and when specifically referring to left and right, the characters left (L) or right (R) are marked in the name of the configuration. In addition, regarding the shapes and configuration positions of the various components described below, except for special statements, they are all the shapes and configuration positions when the passenger seat is in a seatable state.

[0039] First, refer to Figure 1-Figure 3 A first embodiment of the present invention, that is, an overall structure of a vehicle seat 100 including a seat frame 101 will be described. Figure 1 1 is a perspective view showing the appearance of the vehicle seat 100 as seen from the rear. Figure 2 It is a perspective view showing the appearance of a seat frame 101 constituting the framework of the vehicle seat 100 .

[0040] The passenger seat 100 is composed of a seat back S1 for supporting the passenger's back, a seat cushion S2 for supporting the passenger's buttocks, and a headrest S3 for supporting the passenger's head. Each part is constructed by placing cushions S1a, S2a, S3a on a frame as its skeleton and covering them with skins S1b, S2b, S3b.

[0041] Here, if Figure 2 As shown, in the seat frame 101, the seat back frame 1 constituting the frame of the seat back S1 is connected at its lower end to the rear end of the seat cushion frame 2 constituting the frame of the seat cushion S2. In addition, a tilt mechanism (not shown) is provided between the seat back frame 1 and the seat cushion frame 2. According to this, the seat back frame 1 can rotate around the tilt axis 71 relative to the seat cushion frame 2, and the tilt angle (back angle) of the seat back S1 relative to the seat cushion S2 can be freely adjusted. In addition, the tilt axis 71 passes through the lateral lower end of the seat back frame 1 and the lateral rear end of the seat cushion frame 2 and protrudes slightly outward in the width direction.

[0042] A pair of cylindrical headrest guide holders 6 are mounted at the center of the upper end of the seat back frame 1. The headrest support S3c extending from the lower end of the headrest S3 is inserted into the headrest guide holders 6, so that the headrest S3 is mounted to the seat back S1.

[0043] Next, refer to Figure 2 A configuration example of the seat back frame 1 will be described. Figure 2 This is a perspective view showing the appearance of the seat back frame 1 according to the present embodiment. In this figure, the width direction and the height direction are indicated by arrows.

[0044] like Figure 3 As shown, the seat back frame 1 is a substantially rectangular frame body made of metal parts, and includes a pair of side frames 3 provided at both ends in the width direction, an upper tube 4 provided at the end in the height direction, and a lower frame mounting portion 5 provided at the lower end as its main components. In addition, in the present embodiment, the seat back frame 1 is formed by combining and integrating the side frames 3, the upper tube 4, and the lower frame mounting portion 5 in a state of being separated from each other, but it may also be formed integrally from the beginning, that is, integrally formed from a resin material.

[0045] The pair of side frames 3 are separated in the left-right direction to define the width of the seat back S1, and are provided so as to extend in the vertical direction together. When the posture of the passenger seat 100 is in a state where the passenger can sit, the upper end of each side frame 3 is located slightly rearward than the lower end. In addition, the lower end of each side frame 3 is formed to be wider than the upper end in the front-rear direction.

[0046] The upper tube 4 connects the upper ends of the pair of side frames 3, forms an inverted U shape when viewed from the front, and includes a pair of longitudinal frames 4a and a transverse frame 4b connecting the longitudinal frames 4a. The upper tube 4 according to the present embodiment is formed by bending a steel pipe, and both ends thereof are attached to the upper ends of the side frames 3. In addition, in the center of the upper tube 4, the pair of headrest guide holders 6 (sometimes also referred to as pillar support portions) are installed at intervals from each other.

[0047] like Figure 2 As shown in FIG. 1 , a cable 20 is mounted on the upper tube 4 and is laid between a pair of longitudinal frames 4a. The cable 20 is provided to fix the 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 viewed from the center front, and a pair of connecting portions 22 connecting an upper end portion 21a of the bent portion 21 and the longitudinal frames 4a. The bent portion 21 includes a pair of first portions 23 extending downward, and a second portion 24 extending in the left-right direction and connected at the lower ends of the pair of first portions 23.

[0048] like Figure 2 As shown, the seat back frame 1 includes a pressure receiving member 70 formed of an S spring. The pressure receiving member 70 supports the waist of the passenger from behind. The cable 20 and the base cover 10 are provided so as to be located above the pressure receiving member 70.

[0049] In addition, if Figure 1 As shown, the passenger seat 100 of this embodiment is provided with a lighting device 50 on the upper back side of the seat back S1. The lighting device 50 is used to illuminate the foot of the rear seat passenger. A base cover 10 and a panel 30 are provided for fixing the lighting device 50 to the back side of the seat S.

[0050] like Figure 2 As shown, the base cover 10 includes a cover body 15 , a pair of left-right cable fixing portions 11 , 11 for attaching the cover body 15 to the cable 20 , a pair of up-down cable fixing portions 12 , 12 , and a pair of lower claws 14 , 14 .

[0051] The cover body 15 is formed so as to cover a part of the back surface of the seat back, and since it functions as a lighting device 50 , a lighting fitting 51 is mounted inside.

[0052] like Figure 2 and Figure 3 As shown, a pair of left and right cable fixing portions 11 , 11 extend forward from the cover body 15 , and respective top ends 11 a , 11 a hold the connecting portions 22 , 22 of the cable 20 .

[0053] like Figure 2 and Figure 4As shown, a pair of up-and-down cable fixing portions 12 , 12 extend forward from the cover body 15 , and the respective top ends 12 a , 12 a hold the first portions 23 , 23 of the cable 20 , respectively.

[0054] In addition, if Figure 5 As shown, the vertical cable fixing portion 12 has a pair of horizontal restriction portions 13, 13, which are provided at positions adjacent to the first portions 23, 23 in the inner direction of the curved portion 21 and restrict the horizontal movement of the base cover 10. The horizontal restriction portions 13, 13 restrict the horizontal movement by contacting the first portions 23, 23 of the cable 20.

[0055] like Figure 2 and Figure 6 As shown, a pair of lower claws 14 , 14 extend forward from the cover body 15 , and the tips thereof are engaged with the second portion 24 near the bent portions 23 a , 23 a located below the bent portion 21 .

[0056] When the base cover 10 is mounted on the longitudinal frame 4a, the lower claws 14, 14 extending forward from the cover body 15 are hung on the second portion 24 near the curved portions 23a, 23a of the cable 20. In this way, temporary positioning in the left-right direction can be achieved. The base cover 10 is rotated in a state of being hung on the second portion 24, and the top ends 12a, 12a of the vertical cable fixing portions 12, 12 are mounted on the first portions 23, 23 of the cable 20, and the left-right cable fixing portions 11, 11 are mounted on the connecting portions 22, 22 of the cable 20. The left-right movement of the base cover 10 is restricted by making the left-right restriction portions 13, 13 of the vertical cable fixing portions 12, 12 abut against the cable 20.

[0057] like Figure 2 As shown, the left-right cable fixing portions 11, 11 are arranged closer to the vertical frame 4a than the up-down cable fixing portions 12, 12 and the lower claws 14, 14. By configuring in this way, the mounting rigidity can be improved.

[0058] In addition, if Figure 2 As shown, the pair of lower claws 14, 14 are arranged outside the center position of each headrest guide holding portion 6. Thus, even if the headrest support S3c is inserted into the headrest guide holding portion 6 and extends downward, interference with the lower claws 14, 14 can be avoided.

[0059] In addition, in this embodiment, if Figure 2As shown, the left-right direction restriction parts 13, 13 are arranged between the vertical direction cable fixing parts 12, 12 and the lower claws 14, 14 in the height direction. By arranging in this way, when the base cover 10 is installed, the lower claws 14, 14 are used to temporarily position the left-right direction, and by rotating around the lower claws 14, 14, the left-right direction restriction parts 13, 13 abut against the cable 20, the left-right direction position of the base cover 10 is corrected, and the base cover 10 can be fixed by the vertical direction cable fixing parts 12, 12.

[0060] The claws 11 b, 11 b holding the connection portion 22 of the cable 20 at the tip 11 a of the horizontal cable fixing portion 11 are formed to be less easily bent than the claws 12 b, 12 b holding the first portion 23 at the tip 12 a of the vertical cable fixing portion 12 .

[0061] The claws 11b, 11b holding the connection portion 22 of the cable 20 at the tip 11a of the horizontal cable fixing portion 11 are set to have a larger insertion load than the claws 12b, 12b holding the first portion 23 at the tip 12a of the vertical cable fixing portion 12.

[0062] By providing the left and right cable fixing portions 11, 11 in this manner, since the portion (claws 11b, 11b) with a large insertion load is set near the vertical frame 4a, the base cover 10 can be stably mounted.

[0063] Next, a structure for attaching the panel 30 to the base cover 10 will be described. The panel 30 is a plate-shaped member attached to the back surface of the base cover 10 .

[0064] In order to mount the panel 30 on the base cover 10, a plurality of panel fixing portions 19 need to be provided. Figure 3 and Figure 8 As shown, the panel fixing portion 19 is provided with a plurality of clips 191 (upper fixing portion) provided on the upper side of the panel 30 , and a plurality of lower claws 192 (lower fixing portion) are provided on the lower side of the panel 30 .

[0065] A metal SK clip is used as the clip 191 provided on the upper side of the panel 30. However, the clip 191 is not limited to the SK clip, and may be a clip made of resin.

[0066] 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. 1 ) provided on the back side of the panel 30. Figure 3). The base cover 10 is provided with four clips 191, and the holes 37 of the panel 30 are formed at four locations corresponding to the positions of the clips 191. As described above, the clip 191 is a metal SK clip, and the base cover 10 is provided with a base for mounting the SK clip, that is, the clip 191.

[0067] The base cover 10 is provided with a groove 164 along the lower end of the panel 30, and an insertion piece 32 is provided along the lower end and extends forward at the same time. 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 192 has a lower claw 192U with a U-shaped cross section and a lower claw 192J with a J-shaped cross section. Fig.11 As shown, the lower surface of the lower claw portion 192J contacts the lower end of the panel 30. When the insertion piece 32 is inserted into the surface S1b and the groove portion 164 at the same time, the insertion piece 32 is pressed by the lower claw portion 192J and the insertion piece 32 is fixed.

[0068] like Figure 8 As shown, the horizontal positions of the plurality of clips 191 do not overlap with the horizontal positions of the plurality of lower claws 192J and 192U in the vertical direction, but are staggered in the horizontal direction. By staggering in the horizontal direction, the vertical space efficiency is improved.

[0069] Furthermore, since the lower end of the panel 30 is fixed by the lower claw portion 192J having a J-shaped cross section and the lower claw portion 192U having a U-shaped cross section in the groove portion, the panel 30 is fixed while being restricted in the up-down direction, thereby achieving a strong fixation.

[0070] In addition, the back surface of the panel 30 is fixed by the plurality of clips 191 , and the lower end portion (insertion piece 32 ) of the panel 30 is fixed by the groove 164 and the lower claws 192J and 192U of the base cover 10 , so that stable installation can be performed.

[0071] Skin installation structure.

[0072] Next, the structure for attaching the skin S1b to the base cover 10 will be described.

[0073] As described above, the seat frame 101 includes a pad S1a that wraps the seat frame 101 and a skin S1b that covers the seat frame 101 and the pad S1a. In the passenger seat 100 of the present embodiment, in addition to the portion where the panel 30 is installed, the pad S1a that wraps the base cover 10 and the skin S1b that covers the pad S1a are installed on the surface of the base cover 10. In addition, a skin stopper 16 that stops the skin S1b is provided around the portion where the panel 30 is installed on the base cover 10. The decorative string 40 at the end of the back side of the skin S1b is stopped by the skin stopper 16, and the panel 30 is fixed to the base cover 10 in such a manner that the end of the panel 30 overlaps with the device string 40 of the skin S1b in the front-rear direction.

[0074] If you specify, Fig. 9 and Fig.10 As shown, the base cover 10 has an upper skin stopper 161 disposed on the upper side of the base cover 10 and locking the skin as the skin stopper 16. A first guide 17 disposed in the center of the base cover 10 is provided on the opposite surface opposite to the upper skin stopper 161 (see Figure 8 ), and a second guide portion 18 disposed on the right and left sides of the first guide portion 17. The first guide portion uses the wall surface to guide the decorative rope 40 of the skin S1b to the upper skin stop portion 161, and the second guide portion 18 uses the ribs to guide the decorative rope 40 of the skin S1b to the upper skin stop portion 161. By using the first guide portion 17 and the second guide portion 18 to guide the decorative rope 40 below the upper skin stop portion 161, the skin S1b is stopped at the upper skin stop portion 161.

[0075] In addition, the base cover 10 includes side skin locking portions 162 disposed on the left and right sides of the base cover 10 and locking the skin as the skin locking portions 16. The side skin locking portions 162 are disposed so that the top ends 162a of the side skin locking portions 162 face the center of the base cover 10 (see Figure 8 and Fig.12 ).

[0076] A through hole 41 is formed at a position of the decoration string 40 corresponding to the tip 162 a of the side cover locking portion 162 . The decoration string 40 can be locked to the side cover locking portion 162 by inserting the tip 162 a into the through hole 41 .

[0077] The lower claw portion 192 of the insertion piece 32 at the lower end of the fixing panel 30 is arranged at a position that overlaps with the side skin stopper 162 of the base cover 10 in the height direction. This improves the rigidity of the side skin stopper 162.

[0078] In addition, 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 to fix the panel 30. By overlapping and inserting the insertion piece 32 with the decorative string 40, the decorative string 40 is not easy to fall off from the groove 164, and the skin S1b can be firmly fixed. Since the fixing of the skin S1b does not require the use of other parts, the anti-falling structure of the skin S1b can be miniaturized.

[0079] lighting fixtures.

[0080] The vehicle seat 100 includes a lighting device 50 on the back surface of a seat back.

[0081] In the automobile interior lamp disclosed in Utility Model Publication No. 161834, a lighting device is provided on the back of the seat back of the vehicle seat to illuminate the rear seat passengers directly from the front. In the vehicle seat disclosed in Utility Model Publication No. 134946, a lighting device is provided under the seat cushion to illuminate the rear seat passengers' feet.

[0082] In the lighting device for the seat back described in Utility Model Publication No. 161834, the lighting is directed to the rear seat passengers, so the area under the rear seat passengers' feet is not illuminated. In the vehicle seat described in Utility Model Publication No. 134946, the lighting device is short from the lighting device to the feet, so the lighting distance cannot be set, so only a small area under the feet can be illuminated. On the other hand, for example, when the lighting device is installed on the ceiling, the entire area under the rear seat passengers' feet will be illuminated, and it is difficult to illuminate only a part.

[0083] Therefore, the vehicle seat of the present embodiment has been obtained in view of the above-mentioned problems, and provides a vehicle seat including a lighting device capable of easily setting the illumination range under the feet of a rear seat passenger.

[0084] The above-mentioned problem is solved by the following method: a seat back, a lighting device provided on the back side of the seat back and illuminating the area under the feet of a rear seat passenger, the lighting device comprising a base cover mounted on a seat back frame constituting a skeleton of the seat back, a panel mounted on the base cover, and a lighting accessory mounted on the base cover, the base cover having a first opening portion as a light irradiation hole formed below the mounted lighting accessory through which light irradiated from the lighting accessory passes, the panel having a second opening portion as a light irradiation hole formed at a position opposite to the first opening portion when the lighting accessory is mounted on the base cover, the second opening portion being arranged at a position offset by a specific distance from the first opening portion.

[0085] Since the second opening is arranged at a predetermined distance from the first opening, the irradiation range can be easily set with a simple structure.

[0086] In the above-mentioned passenger seat, it is preferred that the seat back frame is wrapped with a pad, the seat back frame and the pad are covered with a skin, and the first opening portion and the second opening portion are arranged below the first opening portion and the second opening portion at a position further rearward than the skin covering the back side of the seat back.

[0087] Since the second opening is arranged at a position further rearward than the surface skin, the light irradiation to the surface skin is not inhibited, and the area under the feet of the rear seat passenger can be irradiated.

[0088] In the above-mentioned vehicle seat, it is preferable that the first opening and the second opening are arranged above a pressure receiving member arranged at a center of the seat back.

[0089] Since the first opening and the second opening are arranged above the pressure-receiving member, the lighting device is not easily affected even if the pressure-receiving member moves rearward.

[0090] In the above-mentioned vehicle seat, it is preferable to include a wall portion extending in the vertical direction around the second opening portion.

[0091] Since the wall portion is provided around the second opening portion, leakage of light from between the first opening portion and the second opening portion can be suppressed, and the distance between the first opening portion and the second opening portion can be easily set.

[0092] In the above-mentioned vehicle seat, it is preferable that, among the wall portions formed around the second opening portion, an upper end of a front wall portion located on the front side is located higher than an upper end of a rear wall portion located on the rear side.

[0093] By changing the height of the wall located on the front side and the wall located on the rear side, it is possible to suppress the generation of noise caused by the first opening being in contact with the entire upper surface of the wall.

[0094] In the above-mentioned vehicle seat, it is preferable that a gap is formed between a rear wall portion located on a rear side of the wall portion formed around the second opening and a lower surface of the base cover.

[0095] Since the gap is formed, it is possible to suppress the generation of noise caused by contact between the first opening of the base cover and the wall on the rear side of the second opening of the panel.

[0096] In the above-mentioned vehicle seat, it is preferable that the lower surface and the rear surface of the panel are formed so as to cover from the lower side to the rear side of the gap.

[0097] By covering the light from the gap with the lower surface and rear surface of the panel, it is possible to suppress light leakage.

[0098] In the above vehicle seat, it is preferable to include an inclined surface that is inclined downward and rearward from the rear of the periphery of the second opening.

[0099] By providing the inclined surface, the light irradiated to the rear can be directed downward, and the light under the feet of the rear seat passengers can be illuminated as indirect lighting.

[0100] In the above-mentioned passenger seat, it is preferred that the lighting accessory has an LED and a light guide. When the lighting accessory is installed on the base cover, the light guide is arranged below the LED, and the light guide is arranged in a manner such that at least a portion overlaps with the first opening in a height direction.

[0101] Since a portion of the light guide overlaps with the first opening in the height direction, miniaturization in the height direction can be achieved, and the amount of light leakage can be suppressed.

[0102] The vehicle seat 100 of this embodiment is as follows: Figure 1 As shown in FIG. 1 , a lighting device 50 is provided on the back of the seat back S1. Figure 1 and Figure 14-16 The lighting device 50 will be described. Figure 1 As shown, the lighting device 50 is a lighting device for illuminating the area under the feet of the rear seat passengers. Fig.14 As shown, the lighting device 50 includes a seat back frame 1, a base cover 10 mounted on the seat back frame 1, and a panel 30 mounted on the base cover 10 (see Fig.16 ), a lighting accessory 51 installed on the base cover 10.

[0103] like Fig.14 As shown, the base cover 10 is provided with a flat support portion 64 for placing the lighting fixture 51, and the lighting fixture 51 is held by an LED holding portion 63 erected from the support portion 64. Fig.15 As shown, the lighting fixture 51 is mounted on the support portion 64 from above. Since the lighting fixture 51 is mounted above the base cover 10, it is possible to suppress damage to the lens of the lighting fixture 51 compared to the case of mounting from the lateral direction or the front-back direction.

[0104] The support portion 64 includes a harness holding portion 61 for holding the harness 60 extending from the lighting fixture 51 and a harness fixing portion 62 for fixing the harness held by the harness holding portion 61. The harness holding portion 61 is provided above the LED holding portion 63, thereby being able to hold a harness of an extra length, thereby improving assembly workability.

[0105] In the base cover 10, a light irradiation hole 52 is formed below the mounted lighting fixture 51, through which light irradiated from the lighting fixture 51 passes. The light irradiation hole 52 is composed of a first opening 53 formed in the base cover 10 and a second opening 54 formed in the panel 30. When the panel 30 is mounted on the base cover 10, the second opening 54 is formed at a position opposite to the first opening 53. Fig.16 As shown, the second opening 54 is arranged at a position offset behind the first opening 53 by a certain distance.

[0106] like Figure 1 As shown, the seat back frame 1 is wrapped with a pad S1 a , and the seat back frame 1 and the pad S1 a are covered with a skin S1 b .

[0107] like Fig.16 As shown, the first opening 53 and the second opening 54 are arranged below the first opening 53 and the second opening 54 and at a position behind the skin S1b covering the back of the base cover 10. By setting the lighting of the lighting device behind the skin S1b, for example, the light irradiation to the skin S1b is not suppressed, and the feet of the rear seat passengers can be appropriately illuminated.

[0108] The first opening 53 and the second opening 54 are arranged at a position closer to the pressure receiving member 70 (see FIG. 1 ) arranged at the center of the seat back S1. Figure 2 ) is located above the pressure-bearing member 70. For example, even if the passenger is subjected to a load in front and the pressure-bearing member moves backward, the lighting device is not easily affected.

[0109] In addition, if Fig.16 As shown, a wall portion 55 extending in the vertical direction is provided around the second opening portion 54 on the panel 30. By providing the wall portion 55, light leakage from between the first opening portion 53 and the second opening portion 54 can be suppressed, and the distance between the first opening portion 53 and the second opening portion 54 can be easily set.

[0110] The wall portion 55 is composed of a front wall portion 551 located in front of the second opening portion 54 and a rear wall portion 552 located in the rear. Fig.16 As shown, the wall portion 55 is formed in a manner that the upper end 551a of the front wall portion 551 is higher than the upper end 552a of the rear wall portion 552. By changing the height of the front wall portion 551 and the rear wall portion 552, the generation of noise caused by the first opening portion 53 contacting the entire top surface of the wall portion 55 is suppressed.

[0111] In addition, a gap 56 of a specific distance L3 is provided between the rear side wall 552 of the second opening 54 and the lower surface of the base cover 10 (the lower surface around the first opening 53). Due to the presence of the gap 56, the generation of noise caused by the contact between the surrounding of the first opening 53 of the base cover 10 and the rear side wall 552 of the second opening 54 of the panel 30 can be suppressed.

[0112] In addition, the lower surface portion 30a and the rear surface portion 30b of the panel 30 are formed from the bottom of the gap 56 to the rear so as to cover the gap 56. By forming the lower surface portion 30a and the rear surface portion 30b of the panel 30 so as to cover the gap 56, light leaking from the gap is intercepted by the lower surface portion 30a and the rear surface portion 30b, thereby preventing light from leaking.

[0113] In addition, an inclined surface 57 is provided which is inclined downward from the rear of the second opening 54. In other words, the lower surface 30a of the panel 30 is inclined downward. By providing the inclined surface 57, the light emitted from the second opening 54 can be set as indirect lighting by directing the light directed backward downward.

[0114] The lighting accessory 51 includes an LED 58 (Light Emitting Diode) and a lens 59 (light guide) for guiding the light emitted from the LED 58. Fig.16 As shown, when the lighting fixture 51 is mounted on the base cover 10, the lens 59 is arranged so as to be located below the LED 58. In addition, at least a portion of the lens 59 is arranged at a position overlapping with the first opening 53 in the height direction.

[0115] By arranging the lens 59 at a position overlapping with the first opening 53 in the height direction, it is possible to achieve miniaturization in the height direction, and by eliminating the gap between the lighting fixture 51 and the first opening 53 , it is possible to suppress the amount of light leakage.

[0116] The diameter L1 of the first opening 53 is set larger than the diameter L2 of the second opening 54. By setting the diameter L1 larger than the diameter L2, the irradiation range of the light from the first opening 53 can be easily narrowed in the second opening 54.

[0117] The embodiments of the present invention are described above with reference to the accompanying drawings. In the above embodiments, a specific example of a passenger seat mounted on a vehicle is described, but the passenger seat is not limited to a vehicle. The passenger seat of the present application can also be used as a seat for a train, a bus, etc., and can also be used as a seat for an airplane or a ship.
