Description

[Technical Field]

[0001] The present invention relates to a slide rail cover that is attached to the end of a slide rail of a vehicle seat, and a slide rail structure of a vehicle seat that uses the same. [Background technology]

[0002] In vehicles, especially automobiles, seats are designed to slide on lower rails that make up the vehicle's slide rails to accommodate different body types and to make effective use of limited cabin space. In recent years, cabin layouts have become more diverse, with three-row seats becoming more common.

[0003] In this case, as shown in Patent Document 1, the third-row seats may get caught on the top of the luggage compartment underfloor storage compartment when slid toward the rear end of their sliding range. The lower rails for sliding the second-row seats are located near the center of the vehicle interior and are covered with floor coverings, whereas the third-row lower rails are largely exposed, which could allow foreign objects to enter through slits in the upper surface of the lower rails. In particular, if the third-row seats can be flipped up to the side of the vehicle interior, the slits in the lower rails may be wider due to a structure in which the seat-side foot rests are detachably attached with hooks or the like to the upper rails that engage with the lower rails, raising concerns about the possibility of foreign objects, such as electronic lighters, getting inside.

[0004] A structure that is said to be able to remove foreign objects that have gotten into a lower rail is described in Patent Document 2. In the structure described in Patent Document 2, a leaf spring that slopes upward as it moves rearward is attached to the rear end of the bottom of the lower rail. As a result, when foreign objects that have gotten into the lower rail are pushed rearward by the sliding rearward of the upper rail, they are lifted upward by the leaf spring, allowing them to be smoothly removed.

[0011] The first, second, third, and fourth aspects of this embodiment will be described with reference to Figures 1 to 6, Figures 8 and 9, Figures 10 and 11, and Figures 12 to 16, respectively. In the drawings described below, identical or similar parts are designated by identical or similar reference numerals. However, it should be noted that the drawings are schematic and may differ from the actual product. Furthermore, the embodiments described below are intended to exemplify devices and methods for embodying the technical ideas, and do not specify the materials, shapes, structures, arrangements, etc. of each component. Various modifications can be made to this embodiment within the scope of the claims.

[0012] (First aspect) 1 to 3 are perspective views of the vicinity of a luggage compartment underfloor storage section 2 in which a slide rail cover 1 according to one embodiment of the present invention is used. FIG. 1 is a perspective view showing a slide rail structure RK according to a first aspect of an embodiment of the present invention, illustrating a vehicle body structure in the vicinity of the luggage compartment underfloor storage section equipped with slide rails for a vehicle seat to which a slide rail cover is attached. FIG. 2 is a perspective view showing a state in which the slide rail cover is not attached, as compared to FIG. 1. FIG. 3 is a perspective view of the vicinity of the luggage compartment underfloor storage section, illustrating a state in which the vehicle body structural material has been covered with a covering material and a deck board has been fitted, as compared to the state in FIG. 1. In the following description, the front-rear, left-right, up-down directions are defined as F for the front, B for the rear, L for the left, R for the right, U for the top, and D for the bottom, as shown by arrows in FIG. 1.

[0013] First, we will explain the third-row seats of an automobile. Figures 1 and 2 show only the luggage compartment underfloor storage area 2 and the left slide rail 3S (3SL) of the pair of left and right slide rails that slide the third-row right seat. Figure 3 also shows the left slide rail 6S (6SL) of the pair of left and right slide rails that slide the second-row right seat and the right slide rail 3S (3SR) of the pair of left and right slide rails that slide the third-row left seat. The luggage compartment underfloor storage section 2 is a portion hollowed out downward at the rear of the vehicle interior and is capable of storing luggage and the like.

[0014] 3, the upper rail (not shown) of the right seat in the third row slides by engaging with a lower rail 81 (81R) laid in the wheelhouse 8 of the right rear wheel. Similarly, the left upper rail (not shown) of the left seat slides by engaging with a lower rail laid in the left wheelhouse (not shown).

[0015] In FIG. 3, a footrest 7 attached to the left bottom of the right seat in the third row can be connected to and disconnected from an upper rail 71 slidably engaged with a lower rail 3L. A footrest (not shown) attached to the right bottom of the right seat is supported rotatably about an axis extending in the front-to-rear direction relative to an upper rail (not shown) engaged with a lower rail 81R laid in a wheelhouse 8. This allows the right seat to be raised (flipped up) against the right side wall of the passenger compartment, opening up the luggage compartment. The left seat in the third row has a similar, symmetrical structure. By flipping up the left and right seats in the third row, the center of the passenger compartment is opened, allowing for the loading of large luggage. A larger passenger compartment can be secured by moving the second-row seats rearward and tilting the seatbacks at a large angle.

[0016] 3, the luggage compartment underfloor storage section 2 shown in FIGS. 1 and 2 is shown with its upper portion closed by a deck board 5. The floor surface in front of the luggage compartment underfloor storage section 2 is covered with a covering material 21 such as a carpet made of nonwoven fabric.

[0017] 1 to 3, the lower rail 3L has a front portion 31 fixed to the vehicle floor and a rear portion 32 fixed to a bridge frame 4 that spans the luggage compartment underfloor storage section 2. As shown in FIG. 2, the bridge frame 4 is fastened to a front frame 202 and a rear frame 201 of the luggage compartment underfloor storage section 2 in the vehicle body 20, thereby contributing to improving the strength of the vehicle body 20.

[0018] The bridge frame 4 is formed from sheet metal in the shape of a long, narrow plate and has longitudinally extending ribs 43 for increased rigidity. The bridge frame 4 has front and rear end portions 41, 42 fastened to the frames 202, 201 with screws 46, and a longitudinal center portion 44 to which a rear end portion 322 of the lower rail 3L is fastened.

[0019] The lower rail 6 (6L) of the second-row seat shown in Fig. 3 is firmly fastened to the vehicle body at the center in the longitudinal direction of the vehicle interior. In contrast, the lower rail 3 (3L) of the third-row seat is directly fastened to the vehicle body at the front portion 31 side (approximately two-thirds of the total length in the example of Fig. 3), but the rear portion 32 side (approximately the remaining one-third of the total length in the example of Fig. 3) extends into the area where the luggage compartment underfloor storage section 2 is formed. By interposing a bridge frame 4 in the mounting structure of the lower rail 3L to the vehicle body, the front and rear of the luggage compartment underfloor storage section 2 are firmly connected, and a high-strength vehicle seat slide rail can be realized at low cost overall without excessively increasing the strength of the lower rail 3.

[0020] Next, the slide rail structure RK and the slide rail cover 1 provided in the slide rail structure RK will be described with reference to Figs. 4 to 7. Fig. 4 is a perspective view of the slide rail cover 1 mounted on the bridge frame 4 described above, Fig. 5 is a longitudinal cross-sectional view thereof, Fig. 6 is an enlarged perspective view of a portion near the slide rail cover 1, and Fig. 7 is a wide longitudinal cross-sectional view including the portion shown in Fig. 6. The slide rail cover 1 in Figs. 4 to 7 is the slide rail cover 1L corresponding to the lower rail 3L. The slide rail cover 1R (Fig. 3) corresponding to the lower rail 3R on the right side of the left seat has a shape symmetrical to the slide rail cover 1L. Hereinafter, the slide rail cover 1L will be described as the slide rail cover 1 unless otherwise specified.

[0021] As shown in Figures 3 to 7, slide rail cover 1 is made of resin and has an elongated shape, and includes an introduction section 11, an ejection section 12, and a support section 13. As shown in Figure 7, slide rail cover 1 is attached to bridge frame 4 with resin rivets 16 or the like, with its longitudinal direction aligned in the front-to-rear direction.

[0022] 7, the introduction portion 11 is formed in a rectangular tubular shape having an internal space 111 that communicates with the space inside the rear end portion 322 of the lower rail 3. A front end surface 112 of the introduction portion 11 abuts against or is close to the rear end surface 323 of the lower rail 3.

[0023] The discharge section 12 is connected to the rear side of the introduction section 11 and has an internal space 121 that communicates with the internal space 111. The discharge section 12 has, in the internal space 111, an inclined surface 1211 that is connected to a bottom surface 1111 that forms the internal space 111 of the introduction section 11 and that slopes upward toward the rear. The discharge section 12 has, at its rear end, an opening 122 that opens into the upper surface of the slide rail cover 1 at a position higher than the height position of the upper surface 33 of the lower rail 3. That is, the rear side of the internal space 121 communicates with the opening 122 and opens upward.

[0024] Support section 13 extends from the bottom of introduction section 11 and discharge section 12 outward to the left, right, and rear so as to have flat support surface 13a (see also FIG. 4). As is clear from FIGS. 3 and 4, support surface 13a supports deck board 5 that is placed on it. Deck board 5, together with support section 13, is placed and supported on a step (not shown) formed on the periphery of luggage compartment underfloor storage section 2, including frames 201, 202.

[0025] With this configuration, as shown in FIG. 7 , a foreign object C, such as an electronic lighter, that has entered the internal space of the lower rail 3L is pushed by the rearward sliding of the upper rail 71 and moves to the rear of the lower rail 3L. The foreign object C moves smoothly from the inner surface 321 of the rear end portion 322 of the lower rail 3, through the internal space 111 of the introduction portion 11 that communicates with the inner surface 321, and reaches the internal space 121 of the discharge portion 12. Furthermore, because the inclined surface 1211 of the discharge portion 12 is inclined upward from the bottom surface 1111 of the introduction portion 11, if the foreign object C is long, it is lifted upward by the inclined surface 1211. In either case, the foreign object C can be seen from the outside through the opening 122, making it easy to detect the presence of the foreign object C. Furthermore, because the opening 122 opens upward, the foreign object C can be easily removed to the outside by inserting a finger or a holding tool such as tweezers through the opening 122 and sliding it along the inclined surface while holding it down, or by grasping it.

[0026] In this way, the slide rail cover 1 has the function of safely and easily expelling foreign matter C that has entered the inner space of the lower rail 3 behind the upper rail 71 from the rear end portion 322 of the lower rail 3.

[0027] The slide rail cover 1 also has support portions 13 and functions to support the deck board 5 placed on the support portions 13. As shown in FIG. 4 , the slide rail cover 1 has a pair of extension portions 132, 133 formed on each of the left and right sides so as to extend forward from a base portion 131 that forms the periphery of the lead-in portion 11 and the discharge portion 12. That is, as shown in FIG. 1 , the slide rail cover 1 is formed in an elongated U-shape in plan view and has a cutout portion 17 that is cut out to accommodate the entry of the rear end portion 322 of the lower rail 3 and expose the portion that is attached to the bridge frame 4. This allows the deck board 5 to be supported over a longer distance by the pair of elongated left and right extension portions 132, 133, which stabilizes the placement of the deck board 5 and further reduces internal stress in the slide rail cover 1 that occurs in accordance with the mass of the supported deck board 5, improving long-term reliability.

[0028] 4, the slide rail cover 1 has an attachment piece 113 near the rear end of the cutout portion 17 at the introduction portion 11. As shown in FIGS. 6 and 7, a locking member 15 is fixed to the attachment piece 113 by a fastener 14 so as to sandwich a rail cover 35 (described in detail later). More specifically, the rail cover 35 is placed over the upper surface 33 of the lower rail 3 as described later, and the rear end of the rail cover 35 is attached by being sandwiched between the attachment piece 113 and the lower rail 3.

[0029] The rail cover 35 is a replaceable component also referred to as a finisher. The rail cover 35 is laid on the upper surface 33 of the lower rail 3 to improve the appearance. As shown in FIG. 6 , the rail cover 35 has a pair of left and right lips 351 that face each other across the center in the left-right direction (width direction) and extend along the lower rail 3. The portions of the pair of lips 351 that do not correspond to the upper rail 71 ( FIG. 7 ) generally close the upper opening of the lower rail 3 in a generally horizontal position, while the portions that correspond to the upper rail 71 bend upward in accordance with the shape of the upper rail 71. This allows the rail cover 35 to close the upper opening of the lower rail 3 as much as possible while allowing the upper rail 71 to slide. The rail cover 35 thus functions to secure the rail cover 35 by being configured so that the end portions 352 of the rail cover 35 can be pressed by the locking members 15.

[0030] A protrusion 151 that protrudes downward and bites into an end 352 of the rail cover 35 is formed on the back surface of the front end of the locking member 15. Correspondingly, the locking member 15 is attached to the mounting piece 113 with a fastener 14 such as a screw or a plastic fastener, and has a locking claw 152 that hooks into a hole 113b on the rear end side of the mounting piece 113. As a result, even if the rail cover 35 gets caught on the upper rail 71, the foot base 7, or the like, the protrusion 151 and the locking claw 152 can prevent the rail cover 35 from shifting.

[0031] Such a vehicle seat slide rail cover 1 is attached to the bridge frame 4, thereby not only improving the aesthetic appearance but also providing additional functions such as making it easy to remove foreign objects that have entered the lower rail 3 and supporting the deck board 5.

[0032] In vehicles with three rows of seats, the third row seats often slide over the luggage compartment underfloor storage area 2. In such cases, the lower rail 3 is installed to straddle the front and rear of the luggage compartment underfloor storage area 2, so the multifunctional slide rail cover 1, which can eject foreign objects C and support the deck board 5, is suitable.

[0033] When the third-row seats can be lifted up to the left or right, the seat bases 7 are detachable from the upper rails 71, which tends to widen the groove width of the lower rails 3. Therefore, the slide rail cover 1 of this embodiment, which has good foreign object ejection properties, is particularly suitable.

[0034] (Second aspect) Fig. 8 is a perspective view of a slide rail cover 1a according to a second embodiment of the present invention, and Fig. 9 is an enlarged cross-sectional view of a portion of the slide rail cover 1a. The slide rail cover 1a has a similar shape to the slide rail cover 1 described above, and corresponding parts are given the same reference numerals and their description will be omitted. Figs. 8 and 9 correspond to Figs. 1 and 5 described above, respectively.

[0035] In this slide rail cover 1a, the introduction section 11a is shorter in the front-to-rear direction than in the slide rail cover 1, and does not have a bottom surface 1111, as if it were a cut-out tube. Instead, the discharge section 12a is provided with a horizontal bottom surface 1213 that connects to the rear inclined surface 1211. An opening 124 on the introduction section 11a side of the bottom surface 1213 has a wider gap from the rear end surface 323 of the lower rail 3 than in the slide rail cover 1, and is used for removing dust, etc.

[0036] The introduction portion 11a has a contact piece 114 that protrudes upward and a pressing piece 115 that extends forward from the upper edge of the contact piece 114. The contact piece 114 faces the rear end surface 353 of the rail cover 35 and is formed as a wall that can be pressed against as needed. The pressing piece 115 protrudes forward beyond the rear end portion 322 of the lower rail 3 and is the portion into which the end portion 352 of the rail cover 35 is inserted. In other words, this introduction portion 11a can hold and press the rear end portion of the rail cover 35 without using the above-mentioned locking member 15. Like the slide rail cover 1, the slide rail cover 1a is also highly functional.

[0037] (Third aspect) Fig. 10 is a partial perspective view of a slide rail cover 1b according to a third embodiment of the present invention, and Fig. 11 is a cross-sectional view taken along the line S11-S11 in Fig. 10. The slide rail cover 1b has a similar shape to the slide rail cover 1a described above, and corresponding parts are designated by the same reference numerals and will not be described again. Figs. 10 and 11 correspond to the vicinity of the discharge section 12a in Figs. 8 and 9, respectively.

[0038] Slide rail cover 1b has discharge portion 12b corresponding to discharge portion 12a of slide rail cover 1a. Discharge portion 12b has opening 124b, which has walls that protrude in the vertical and horizontal directions and narrows the opening portion relative to opening 124 in discharge portion 12a. That is, the slide rail cover 1b has a lower extending wall 114b extending downward from the contact piece 114, and a left wall 114c and a right wall 114d extending inward from the left and right walls. Furthermore, the bottom surface 1213 and the inclined surface 1211 of the discharge portion 12b are connected by a curved connection portion 1214 with a smaller curvature than the discharge portion 12a.

[0039] The lower rail 3 has an extension portion 3231 whose bottom portion extends tongue-like further rearward from the rear end surface 323 to the vicinity of the opening 124b. The extension portion 3231 may extend so as to enter the interior of the opening 124b, as shown in Fig. 11. The width and position of the opening 124b in the left-right direction generally coincide with the width of the space in the lower rail 3 through which the foreign object C can move in the front-rear direction.

[0040] With these configurations, foreign object C, such as an electronic lighter, that is pushed rearward by upper rail 71 (see FIG. 7) of base 7 is supported by extension 3231 and guided into opening 124b without getting caught on stopper piece 114, with a leading portion passing through opening 124b. After passing through opening 124b, the leading portion of foreign object C is guided along curved connecting portion 1214 and raised, as shown in FIG. 11. This allows foreign object C to be easily picked up with fingers or the like and removed.

[0041] (Fourth aspect) Fig. 12 is a perspective view of a slide rail cover 1A according to a fourth aspect of the embodiment of the present invention, viewed from diagonally above and behind the right. Fig. 13 is a partial perspective view of the rear of the slide rail cover 1A of Fig. 12, viewed from diagonally below and behind the right. Fig. 14 is a partial cross-sectional perspective view of a slide rail structure RKA including a slide rail 3SA for a vehicle seat according to the fourth aspect, viewed from diagonally above and behind the right. Fig. 15 is a cross-sectional view of the slide rail structure RKA shown in Fig. 14, cut along a horizontal plane at height position S15-S15. Fig. 16 is a perspective view of the slide rail structure RKA of the fourth aspect, viewed from diagonally above and behind the right.

[0042] A slide rail structure RKA according to a fourth embodiment of the present invention includes a slide rail cover 1A. The slide rail cover 1A has a foreign object C ejection section provided at one of the left and right rear corners of the rear portion. Specifically, as shown in FIGS. 12 and 13, the slide rail cover 1A is formed in a generally U-shape with a notch 11A3 in a top view. The rearmost portion of the slide rail cover 1A has an uppermost portion 11A1 that protrudes upward and forms the rear edge of the notch 11A3, and a stepped portion 11A2 that is connected to the rear side and is one step lower. An ejection section 12A is formed at the lower edge of the right rear corner of the slide rail cover 1A, notched upward.

[0043] 13, a rib-like guide plate 18A that extends obliquely from the front left to the rear right and protrudes downward is formed on the underside of the slide rail cover 1A. The guide plate 18A has first to fourth guide portions 18A1 to 18A4 with different inclination angles, and is formed so that the width of the inside of the slide rail cover 1A in the left-right direction as it approaches the discharge portion 12A as a whole.

[0044] As shown in Fig. 14, a bridge frame 4A similar to the bridge frame 4 of the first embodiment (see Fig. 1) is disposed above the luggage compartment underfloor storage section 2 so as to extend in the front-to-rear direction. Similarly to the first embodiment, a lower rail 3A (see Fig. 15) extending in the front-to-rear direction is fixed to the front of the bridge frame 4A. A slide rail cover 1A is fixed to cover the rear of the lower rail 3A. As shown in Fig. 14, a pair of rail covers 35, 35 are attached to the upper surface of the slide rail cover 1A.

[0045] As shown in Fig. 15, a slide rail 3SA is engaged with the lower rail 3A so as to be slidable in the front-rear direction, and a foot stand 7 fixed to the slide rail 3SA and extending upward extends upward from a gap between a pair of rail covers 35, 35 (see Fig. 14). As a result, the foot stand 7 and the slide rail 3SA slide in the front-rear direction as indicated by an arrow DR1 in Fig. 14.

[0046] In the above-described configuration, a foreign object C (dash-dotted line) that has entered the interior of the lower rail 3A behind the slide rail 3SA is pushed rearward as the slide rail 3SA moves rearward (see arrow DR20) as shown in Fig. 15. The foreign object C pushed rearward comes into contact with the guide plate 18A that is installed at an angle, and is guided so as to be deflected to the right (see arrow DR2), and is then discharged to the outside from the discharge portion 12A formed at the right rear edge of the slide rail 3SA (see arrow DR3 in Figs. 14 and 15).

[0047] Foreign object C discharged from discharge portion 12A falls directly into the luggage compartment underfloor storage section 2. As shown in FIG. 16, the luggage compartment underfloor storage section 2 is covered by fitting divided deck boards 5A1, 5A2 of deck board 5A so as to conceal discharge portion 12A. In other words, only the top portion 11A1 of slide rail cover 1A and rail covers 35, 35 are exposed from deck board 5A. As a result, the slide rail structure RKA has no exposed openings around slide rail cover 1A, achieving a high level of appearance quality.

[0048] Furthermore, with the slide rail structure RKA, foreign object C that has entered the lower rail 3A naturally falls into the luggage compartment underfloor storage area 2 as the foot rest 7 moves rearward, and the fallen foreign object C can be easily removed by removing the separate deck boards 5A1, 5A2. In other words, foreign object C that has entered the interior of the lower rail 3A is easily ejected and can be easily collected. The position of the ejection portion 12A is not limited to the right rear corner, but may also be the left rear corner.

[0049] As described above in detail, the slide rail structures RK, RKA, which are one embodiment of the present invention, the slide rail covers 1, 1a, 1b provided in the slide rail structure RK, and the slide rail cover 1A provided in the slide rail structure RKA can easily expel foreign matter C that has entered the interior of the lower rail 3, and because the slide rail cover 1 is multifunctional, parts solely for expelling foreign matter C are not required, thereby suppressing cost increases.
