Description

[Technical Field]

[0001] The present invention relates to a vehicle seat, and more particularly to a hinge cover assembly that covers a side frame of a seat cushion. [Background technology]

[0002] In the vehicle seat disclosed in Patent Document 1 below, a locking bracket (electrical component cover) that covers electrical components attached to a shield (hinge cover) of the seat cushion from the inside in the seat width direction has a connecting protrusion (claw) that is inserted into a locking hole in the side frame of the seat cushion. The inclined structure of the tip of this claw guides the claw into the locking hole. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-30491 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art, when inserting the claws of the electrical equipment cover into the locking holes of the side frame, the trim cover and hinge cover of the seat cushion get in the way, making it difficult to see the claws and locking holes, making the insertion process complicated.

[0005] An object of the present invention is to provide a hinge cover assembly and a vehicle seat that facilitate the insertion of the claws of an electrical component cover into the locking holes of a side frame. [Means for solving the problem]

[0006] The hinge cover assembly of the first aspect comprises a hinge cover that covers the side frame of the seat cushion of a vehicle seat from the outside in the seat width direction, electrical equipment attached to the hinge cover and positioned between the side frame and the hinge cover, and an electrical equipment cover that is attached to the hinge cover and covers the electrical equipment from the inside in the seat width direction, wherein the front part of the electrical equipment cover is provided with an insertion portion into which an insertion piece provided at the front end of the side frame is inserted from the rear side in the seat front-to-rear direction, and the rear part of the electrical equipment cover is provided with a claw portion that protrudes toward the inside in the seat width direction and is inserted into a locking hole formed in the side frame, and the tip surface of the claw portion is inclined so that it faces outward in the seat width direction as it moves toward the rear side in the seat front-to-rear direction.

[0007] In a first aspect of the hinge cover assembly, the side frames of the seat cushion of a vehicle seat are covered from the outer side in the seat width direction by the hinge cover. Electrical equipment attached to the hinge cover is disposed between the side frame and the hinge cover and is covered from the inner side in the seat width direction by the electrical equipment cover attached to the hinge cover. The front part of the electrical equipment cover is provided with an insertion portion into which an insertion piece provided at the front end of the side frame is inserted from the rear side in the seat front-rear direction. The rear part of the electrical equipment cover is provided with a claw portion that protrudes toward the inner side in the seat width direction and is inserted into a locking hole formed in the side frame. The tip surface of the claw portion is inclined so that it approaches the outer side in the seat width direction as it approaches the rear side in the seat front-rear direction.

[0008] To assemble the hinge cover assembly to the side frame, simply insert the insertion piece at the front end of the side frame into the insertion portion of the electrical equipment cover and rotate the hinge cover inward in the seat width direction around the insertion portion. This allows the claw portion of the electrical equipment cover to be aligned with the locking hole in the side frame in the seat's fore-and-aft direction. Even if there is some misalignment between the claw portion and the locking hole in the seat's fore-and-aft direction, the inclined tip surface of the claw as described above slides against the edge of the locking hole, guiding the claw portion into the locking hole. This simplifies the process of inserting the claw portion into the locking hole.

[0009] The second aspect of the hinge cover assembly is the same as the first aspect, in which the claw portion has an upper wall and a lower wall that face each other in the up-down direction of the seat, and a front wall and a rear wall that face each other in the fore-and-aft direction of the seat, and is shaped like a rectangular tube when viewed in the seat width direction, with the tip surface of the front wall extending linearly along the up-down direction of the seat.

[0010] In the hinge cover assembly of the second aspect, the claw portions of the electrical equipment cover are shaped like square tubes as described above, and the tip surfaces of the claw portions are inclined outward in the seat width direction as they extend toward the rear of the seat. Therefore, as described above, when the hinge cover is rotated inward in the seat width direction around the insertion portion of the electrical equipment cover, the tip surfaces of the front walls of the claw portions may come into contact with the side frame. However, the tip surfaces of the front walls extend linearly in the up-down direction of the seat. By the tip surfaces of the front walls coming into linear contact with the side frame, deformation of the tip surfaces of the claw portions can be prevented or effectively suppressed.

[0011] The hinge cover assembly of the third aspect is the first or second aspect, in which the dimensions of the electrical equipment cover are set so that when the insertion piece is fully inserted into the insertion portion, the claw portion is shifted rearward in the fore-and-aft direction of the seat relative to the locking hole.

[0012] In the hinge cover assembly of the third aspect, when the insertion pieces of the side frames are fully inserted into the insertion portions of the electrical component cover, the claw portions of the electrical component cover are shifted rearward in the seat fore-and-aft direction relative to the locking holes of the side frames. In this state, by rotating the hinge cover inward in the seat width direction around the insertion portions of the electrical component cover, the tip surfaces (i.e., inclined surfaces) of the claw portions can be easily engaged with the rear edges of the locking holes, and the sliding contact between the tip surfaces of the claw portions and the rear edges of the locking holes makes it easier to guide the claw portions into the locking holes.

[0013] A fourth aspect of the vehicle seat includes a seat cushion on which a vehicle occupant sits, a seat back that supports the back of the occupant, and a hinge cover assembly of any one of the first to third aspects, in which the side frame of the seat cushion is covered from the outside in the seat width direction with the hinge cover.

[0014] In the vehicle seat of the fourth aspect, the back of an occupant seated on a seat cushion is supported by the seat back. The side frames of the seat cushion are covered from the outside in the seat width direction by hinge covers provided in a hinge cover assembly. This hinge cover assembly is one of the first to third aspects, and therefore the above-mentioned effects can be obtained. [Effects of the Invention]

[0015] As described above, the hinge cover assembly and vehicle seat according to the present invention facilitate the operation of inserting the claws of the electrical component cover into the locking holes of the side frames. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0017] First Embodiment A vehicle seat 10 according to a first embodiment of the present invention will be described below with reference to Figures 1 to 14. Note that in each figure, some reference numerals may be omitted to make the drawings easier to understand. Arrows FR, LH, RH, and UP, which are appropriately shown in each figure, respectively indicate the front, left, right, and top of the vehicle seat 10. Hereinafter, when the front-rear, left-right, top-bottom directions are used in the description, they will indicate directions relative to the vehicle seat 10.

[0018] 1, a vehicle seat 10 according to the first embodiment includes a seat cushion 12 on which a vehicle occupant sits, a seatback 14 that supports the back of the occupant, a headrest 16 that supports the head of the occupant, and a hinge cover assembly 30. This vehicle seat 10 is, for example, a front seat located on the left side of the front part of the vehicle compartment. When this vehicle seat 10 is located on the right side of the front part of the vehicle compartment, the configuration is symmetrical to that of this embodiment.

[0019] 2 and 3, a cushion frame including the side frames 18, a cushion pad 24 (see FIG. 1) attached to the cushion frame, and a trim cover 26 (see FIG. 1) covering the cushion pad 24. The cushion pad 24 is made of a foam such as urethane foam, and the trim cover 26 is made into a bag shape by sewing together multiple skin pieces made of, for example, cloth, leather, synthetic leather, or the like.

[0020] The cushion frame has a pair of left and right side frames 18 (the right side frame 18 is not shown), a front frame (not shown) that connects the front portions of the left and right side frames 18 in the left-right direction, and a rear frame (not shown) that connects the rear portions of the left and right side frames 18 in the left-right direction. The left and right side frames 18 and the front frame are made of, for example, press-formed metal plate material, and the rear frame is made of, for example, metal pipe material. A back frame (not shown) that forms the framework of the seat back 14 is connected to the rear portions of the left and right side frames 18 via a reclining mechanism (not shown).

[0021] The hinge cover assembly 30 is disposed on the left side of the seat cushion 12. As shown in Figures 2 to 4, the hinge cover assembly 30 includes a hinge cover 32, a switch unit 34 which is an electrical component, a harness 46 connected to the switch unit 34, and a switch cover 50 which is an electrical component cover.

[0022] The hinge cover 32 is manufactured by, for example, resin injection molding and has an elongated shape with its longitudinal direction extending in the front-to-rear direction. The hinge cover 32 is attached to the left side frame 18 (hereinafter simply referred to as the "side frame 18") and covers the side frame 18 and the reclining mechanism from the outer side in the seat width direction (here, the left side).

[0023] A switch unit 34 is attached to the inner surface in the seat width direction (here, the right surface) of the hinge cover 32 at the middle portion in the front-rear direction. The switch unit 34 has a long switch case 36 whose longitudinal direction is in the front-rear direction. The switch case 36 is fixed to the hinge cover 32 with a plurality of screws 38 (here, three). A plurality of switches (here, three) not shown are provided inside the switch case 36. These switches are configured to be turned on and off by operating knobs 40, 42, and 44 shown in FIG. 1.

[0024] A connector 48 provided at one end of a harness 46 is connected to the front end of the switch case 36. The harness 46 extends forward from the front end of the switch case 36 and then extends inward in the seat width direction (to the right in this case). The switch unit 34, the connector 48, and a portion of the harness 46 are covered from the inside in the seat width direction by a switch cover 50 attached to an inner surface in the seat width direction (to the right in this case) of a middle portion of the hinge cover 32 in the front-rear direction.

[0025] 3 to 6, the switch cover 50 is manufactured by, for example, resin injection molding and has an elongated shape with its length extending in the front-to-rear direction. The switch cover 50 has an upper wall 52 and a lower wall 54 that face each other in the vertical direction, and a side wall 56 that connects the inner ends (here, right ends) of the upper wall 52 and the lower wall 54 in the seat width direction in the vertical direction, and has an open cross-sectional shape that is open on the outer side (here, left side) in the seat width direction when viewed from the front-to-rear direction.

[0026] A plurality of (three in this example) mounting pieces 58 protruding upward are provided on the outer end of the upper wall 52 in the seat width direction, and a plurality of (two in this example) mounting pieces 58 protruding downward are provided on the outer end of the lower wall 54 in the seat width direction. Each of these mounting pieces 58 has a circular mounting hole 60 formed therein, and a screw 62 (see FIG. 3) inserted into each mounting hole 60 is threaded into a screw hole (reference number omitted) formed in the hinge cover 32. In this way, the switch cover 50 is fixed to the hinge cover 32.

[0027] The front portion 50A of the switch cover 50 covers the connector 48 and part of the harness 46 from the inside in the seat width direction, and the rear portion 50B of the switch cover 50 covers the front portion of the switch unit 34 from the inside in the seat width direction. The middle portion of the switch cover 50 in the front-to-rear direction is bent in a crank shape, and the front portion 50A of the switch cover 50 is positioned higher than the rear portion 50B of the switch cover 50.

[0028] An insertion portion 64 is provided on the inner surface (here, the right surface) in the seat width direction of the front portion 50A of the switch cover 50, into which the insertion piece 20 formed on the front end of the side frame 18 is inserted from the rear side. The insertion piece 20 has an oblique extension portion 20A that extends obliquely to the left and forward from the front end of the side frame 18, and a front extension portion 20B that extends forward from the front end of the oblique extension portion 20A. An insertion hole 66 that opens toward the rear side is formed in the insertion portion 64, and the front extension portion 20B of the insertion piece 20 is inserted into the insertion hole 66. This allows the front portion 50A of the switch cover 50 to be engaged with the front end of the side frame 18.

[0029] 4 to 7, a protrusion 68 that protrudes inward in the seat width direction is formed on the inner surface (here, the right surface) of the rear portion 50B of the switch cover 50 in the seat width direction. The protrusion 68 is generally box-shaped with an open lower side. A claw 70 that protrudes inward in the seat width direction is formed on the tip surface of this protrusion 68.

[0030] The claw portion 70 has an upper wall 72 and a lower wall 74 that face each other in the vertical direction, and a front wall 76 and a rear wall 78 that face each other in the front-rear direction, and has a rectangular cylindrical shape when viewed in the seat width direction (left-right direction). The dimension of the claw portion 70 in the front-rear direction is set to be larger than the dimension of the claw portion 70 in the vertical direction. Two front and rear ribs 80 are provided on the upper surface of the upper wall 72, and two front and rear ribs 82 are provided on the lower surface of the lower wall 74. Two upper and lower ribs 84 are provided on the front surface of the front wall 76, and two upper and lower ribs 86 are provided on the rear surface of the rear wall 78. These ribs 80, 82, 84, and 86 are integrally connected to the tip surface of the protrusion 68. The front and rear ribs 80 have a step 80A on the protrusion 68 side, and the step 80A increases the upward protrusion height.

[0031] The tip surface TS of the claw portion 70 is inclined toward the outer side in the seat width direction (here, toward the left side) as it extends toward the rear, and the tip shape of the claw portion 70 is single-edged when viewed in the vertical direction. A tip surface TS1 of the front wall 76 that constitutes a part of the tip surface TS of the claw portion 70 is located more inward in the seat width direction than other parts of the tip surface TS of the claw portion 70. The tip surface TS1 of the front wall 76 extends linearly in the vertical direction. The tip surface TS1 is formed in a flat shape that extends in the vertical and front-to-rear directions.

[0032] 2 and 9 to 12, the claw portion 70 is inserted from the outer side in the seat width direction (here, the left side) into a locking hole 22 formed in a longitudinally intermediate portion of the side frame 18. The locking hole 22 is formed in a generally rectangular shape (a generally oval shape) with its longitudinal direction extending in the longitudinal direction when viewed from the left and right. As shown in FIG. 10, upper and lower ribs 84 formed on the front wall 76 of the claw portion 70 engage (contact or closely face each other; the same applies below) with the front edge of the locking hole 22 from the rear side, and upper and lower ribs 86 formed on the rear wall 78 of the claw portion 70 engage with the rear edge of the locking hole 22 from the front side.

[0033] As shown in Figures 9, 10, and 12, the front and rear ribs 80 formed on the upper wall 72 of the claw portion 70 engage from below with the upper edge of the locking hole 22, and the step portions 80A of the front and rear ribs 80 engage with the upper edge of the locking hole 22 from the left side. The front and rear ribs 82 formed on the lower wall 74 of the claw portion 70 engage from the left side with the lower edge of the locking hole 22, and the elastic claw 88 formed on the lower wall 74 engages from the right side. This locks the claw portion 70 to the side frame 18 in the left-right direction. The elastic claw 88 is elastically deformable upward. When the claw portion 70 is inserted into the locking hole 22, the elastic claw 88 is elastically deformed and then elastically returns to its original shape.

[0034] In the hinge cover assembly 30 configured as described above, the hinge cover 32, to which the switch unit 34 and the switch cover 50 are attached, is assembled to the side frame 18 via the switch cover 50. When this hinge cover assembly 30 is assembled to the side frame 18, first, the front extension portion 20B of the insertion piece 20 provided at the front end portion of the side frame 18 is inserted from the rear side into the insertion hole 66 formed in the insertion portion 64 of the switch cover 50.

[0035] 13 , when the insertion piece 20 is fully inserted into the insertion portion 64, the rear end of the insertion portion 64 comes into contact with the obliquely extending portion 20A of the insertion piece 20 from the front side. This restricts rearward displacement of the switch cover 50 relative to the side frame 18. In this state, when the switch cover 50 (i.e., the hinge cover assembly 30) is rotated inward in the seat width direction (here, to the right) around the insertion portion 64, the tip end surface TS of the claw portion 70 is configured to come into contact with the vicinity of the rear edge of the locking hole 22 of the side frame 18. In other words, the front-to-rear dimension of the switch cover 50 is set so that the claw portion 70 is displaced rearward relative to the locking hole 22 when the insertion piece 20 is fully inserted into the insertion portion 64.

[0036] When the switch cover 50 (i.e., the hinge cover assembly 30) is pushed inward in the seat width direction with the tip surfaces TS of the claw portions 70 abutting against the rear edges of the locking holes 22, the tip surfaces TS of the claw portions 70 slide against the rear edges of the locking holes 22, and the inclination of the tip surfaces TS guides the claw portions 70 into the locking holes 22. As a result, as shown in FIG. 14 , the claw portions 70 are inserted into the locking holes 22. At this time, the switch cover 50 is displaced slightly forward relative to the side frames 18, and the rear ends of the insertion portions 64 are separated forward from the obliquely extending portions 20A of the insertion pieces 20. Note that, as shown in FIGS. 13 and 14 , the insertion holes 66 are formed so that their width in the left-right direction increases as they extend forward. This allows the switch cover 50 to rotate about the insertion portions 64 as described above.

[0037] 15 and 16 , if the claw portion 70 is displaced upward or downward relative to the locking hole 22 during the insertion of the claw portion 70 into the locking hole 22, the tip surface TS of the claw portion 70 will abut against the side frame 18. At this time, because the tip surface TS of the claw portion 70 is inclined so as to be directed outward in the seat width direction as it extends toward the rear, the tip surface TS1 of the front wall 76 (the portion marked with a dot in FIG. 8) abuts against the side frame 18. The tip surface TS1 of the front wall 76 extends linearly in the up-down direction and is therefore configured to abut against the side frame 18 in a linear manner.

[0038] In the vehicle seat 10 configured as described above, the back of an occupant seated on the seat cushion 12 is supported by the seat back 14. The seat cushion 12 is covered from the outside in the seat width direction by the side frames 18 and the resin hinge cover 32 provided on the hinge cover assembly 30. The switch unit 34 attached to the hinge cover 32 is disposed between the side frames 18 and the hinge cover 32 and is covered from the inside in the seat width direction by a switch cover 50 attached to the hinge cover 32. A front portion 50A of the switch cover 50 is provided with an insertion portion 64 into which an insertion piece 20 provided at the front end of the side frame 18 is inserted from the rear side. A rear portion 50B of the switch cover 50 is provided with a claw portion 70 that protrudes toward the inside in the seat width direction and is inserted into a locking hole 22 formed in the side frame 18. A tip surface TS of the claw portion 70 is inclined so as to be outward in the seat width direction as it approaches the rear side in the seat front-rear direction.

[0039] When assembling the hinge cover assembly 30 to the side frame 18, the insertion piece 20 at the front end of the side frame 18 is inserted into the insertion portion 64 of the switch cover 50, and the hinge cover 32 is rotated inward in the seat width direction around the insertion portion 64. This allows the claw portion 70 of the switch cover 50 to be aligned with the locking hole 22 of the side frame 18 in the front-to-rear direction. Even if there is some misalignment between the claw portion 70 and the locking hole 22 in the front-to-rear direction of the seat, the tip surface TS of the inclined claw portion 70 as described above slides against the edge portion (here, the rear edge portion) of the locking hole 22, thereby guiding the claw portion 70 into the locking hole 22. This facilitates the insertion of the claw portion 70 into the locking hole 22, and also facilitates the assembly of the hinge cover assembly 30.

[0040] Furthermore, the claw portion 70 has a front wall 76 and a rear wall 78 that face each other in the front-to-rear direction, and an upper wall 72 and a lower wall 74 that face each other in the up-down direction, and has a rectangular cylindrical shape when viewed in the seat width direction, and the tip surface TS of the claw portion 70 is inclined so as to face outward in the seat width direction as it extends toward the rear. Therefore, when the hinge cover 32 is rotated inward in the seat width direction around the insertion portion 64 of the switch cover 50 as described above, the tip surface TS1 of the front wall 76 of the claw portion 70 may abut against the side frame 18, but the tip surface TS1 of the front wall 76 extends linearly in the up-down direction. This linear abutment of the tip surface TS1 of the front wall 76 with the side frame 18 prevents or effectively suppresses deformation of the tip surface TS of the claw portion 70.

[0041] This effect will be further explained using a comparative example shown in Figures 17 to 19. In Figures 17 to 19, the same reference numerals are used to designate the same components as in this embodiment. In this comparative example, the tip surface TS' of the claw portion 70' is V-shaped when viewed in the vertical direction, and the tip of the claw portion 70' has a double-edged shape. The front part of the tip surface TS' is inclined so that it slopes outward in the seat width direction (to the left in this case) as it moves forward, and the rear part of the tip surface TS' is inclined so that it slopes outward in the seat width direction as it moves rearward.

[0042] 18 and 19 , when the claw portion 70′ is inserted into the locking hole 22, if the claw portion 70′ is misaligned upward or downward with respect to the locking hole 22, the center portions of the tip surfaces TS′ of the claw portions 70′ in the front-to-rear direction (two locations marked with black squares in FIG. 17 ) may come into point contact with the side frame 18, causing deformation of the tip surfaces TS′. If the upper wall 72 and the lower wall 74 are separated in the vertical direction due to this deformation of the tip surfaces TS′, the claw portions 70′ cannot be inserted into the locking hole 22. However, in this embodiment, the tip surfaces TS1 of the front wall 76 come into line contact with the side frame 18, thereby preventing or effectively suppressing deformation of the tip surfaces TS. This makes it possible to avoid a situation in which the claw portions 70 cannot be inserted into the locking holes 22.

[0043] Furthermore, in this embodiment, when the insertion pieces 20 of the side frames 18 are fully inserted into the insertion portions 64 of the switch cover 50, the claw portions 70 of the switch cover 50 are shifted rearward in the seat front-rear direction relative to the locking holes 22 of the side frames 18. In this state, by rotating the hinge cover 32 inward in the seat width direction around the insertion portions 64 of the switch cover 50, as shown in Fig. 13, the tip surfaces (i.e., inclined surfaces) of the claw portions 70 can be easily engaged with the rear edges of the locking holes 22, and the sliding contact between the tip surfaces of the claw portions 70 and the rear edges of the locking holes 22 makes it easier to guide the claw portions 70 into the locking holes 22.

[0044] Although the present invention has been described above with reference to the embodiments, the present invention can be practiced with various modifications without departing from the spirit of the invention. Furthermore, it goes without saying that the scope of the present invention is not limited to the above-described embodiments. [Explanation of symbols]
