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 the limited space inside the vehicle. In recent years, vehicle interior 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 or the like, whereas the third-row lower rails are largely exposed, and there is a possibility that foreign objects may enter through slits in the upper surfaces of the lower rails. In particular, when the third-row seats can be flipped up to the side of the vehicle interior, the slits in the lower rails may be widened by using a structure in which the foot rests on the seat side are detachably attached with hooks or the like to the upper rails that engage with the lower rails, raising concerns that foreign objects such as electronic lighters may become trapped inside.

[0004] If a foreign object gets inside the lower rail, it may cause problems such as the seat becoming difficult to slide. If the foreign object is an electronic lighter, it will be 60 to 80 mm in length, which increases the possibility of problems with the seat sliding. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 5348069 Summary of the Invention [Problem to be solved by the invention]

[0006] On the other hand, the second and third lower rails are usually arranged in a straight line, and a certain amount of gap occurs at the butt point where the rear end of the second lower rail and the front end of the third lower rail meet due to their structure. Therefore, from the perspective of appearance quality and preventing the intrusion of foreign objects, a cover that can conceal the gap at the butt point and prevent the intrusion of foreign objects is required. Furthermore, it is desirable for this cover to have the function of easily removing foreign objects even if they do get into the lower rails.

[0007] SUMMARY OF THE INVENTION An object of the present invention is to provide a multifunctional slide rail cover and slide rail structure for a vehicle seat, which covers the gap between the ends of the slide rail of the vehicle seat. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0011] First and second embodiments of the present invention will be described with reference to FIGS. 1 to 7 and 8 to 11, respectively. In the drawings described below, identical or similar parts are designated by identical or similar reference numerals. It should be noted that the drawings are schematic and may differ from the actual product. Furthermore, the embodiments shown below exemplify devices and methods for embodying the technical ideas, and do not specify the materials, shapes, structures, arrangements, etc. of each component part.

[0012] (First aspect) FIG. 1 is a perspective view showing the structure of a vehicle equipped with a slide rail cover 2 (2L, 2R) for a vehicle seat according to a first embodiment of the present invention, near a luggage compartment underfloor storage area. The slide rail cover 2 (2R) is a cover that covers the joint between the rear end 61 of the second-row lower rail 6 (6R) and the front end 31 of the third-row lower rail 3 (3R), which constitute the slide rail of a vehicle seat (not shown). Of the pair of lower rails for the second row, only the right lower rail 6R is shown in FIG. 1. Because the pair of lower rails 3L, 3R have substantially the same structure, the following description will focus on the right lower rail 3R as a representative, and in cases where it is not necessary to distinguish between left and right, the letters L and R will be omitted.

[0013] In this embodiment, the second-row lower rail 6 (6R) and the third-row lower rail 3 (3L, 3R) are arranged in a straight line, and structurally, there is a gap where they meet. Therefore, to improve the appearance and prevent the intrusion of foreign matter, a slide rail cover 2 (2R) is attached to cover the gap at the meet and to prevent foreign matter from entering through the gap. Hereinafter, the front second-row lower rail 6 will also be referred to as the first lower rail 6, and the rear third-row lower rail 3 will also be referred to as the second lower rail 3.

[0014] 1 is a perspective view of the slide rail structure RK when the rear door of a vehicle M is opened and the view is seen diagonally downward from behind the third-row seats. Below the third-row seats (not shown), a trunk underfloor storage area 51 capable of accommodating luggage and the like is formed as a portion hollowed out downward at the rear of the vehicle interior. The trunk underfloor storage area 51 is covered with a deck board 5.

[0015] In FIG. 1, the floor surface in front of the luggage compartment under-floor storage section 51 is covered with a covering material 52 such as a carpet made of nonwoven fabric. For the sake of simplicity, FIG. 1 shows a lower rail 3 (3R) for the right seat (not shown) in the third row and a lower rail 6 (6R) for the right seat (not shown) in the second row. An upper rail 71 connected to the bottom of the left footrest 7 of the right seat in the second row engages with and slides on the lower rail 3R. An upper rail (not shown) on the right side of the left seat in the second row (not shown) engages with and slides on the lower rail 3L.

[0016] The right upper rail (not shown) of the third-row right seat slides by engaging with a lower rail 81 (81R) laid in the rear wheel house 8. The left upper rail of the third-row left seat also slides by engaging with a lower rail laid in the wheel house (not shown).

[0017] The footrests 7 can be engaged with and disengaged from the upper rails 71, and the footrests (not shown) on the wheelhouse 8 side can rotate about the front-to-rear axis. Therefore, the left and right seats in the third row can be flipped up to the left and right, respectively, opening up the center of the passenger compartment. This frees up the center of the passenger compartment, making it possible to load large luggage, and also ensuring a large seating space by lowering the second-row seats backward or laying them flat.

[0018] Fig. 2 is a perspective vertical cross-sectional view of the slide rail structure RK, showing the butt joint between the rear end 61 of the second-row lower rail 6R and the front end 31 of the third-row lower rail 3R. Fig. 3 is a perspective view, seen from diagonally above left, of the slide rail structure RK with the slide rail cover removed from Fig. 2. A gap S is formed at this butt joint, and the slide rail cover 2 is fitted in to cover the gap S.

[0019] Fig. 4 is a first perspective view of the slide rail cover 2 seen from the upper left rear, Fig. 5 is a second perspective view of the slide rail cover 2 seen from a higher position than in Fig. 4. Fig. 6 is a third perspective view of the slide rail cover 2 seen from slightly above the left, and Fig. 7 is a fourth perspective view of the slide rail cover 2 seen from the lower left rear.

[0020] The slide rail cover 2 includes a cover body 21, a pair of arms 22, 23, and a bottom 24. The cover body 21 is a plate-like member formed to be sufficiently longer than the longitudinal distance between the butt joints so as to cover the gap S at the butt joints. The cover body 21 is fixed to the lower rail 6 or the lower rail 3. The cover body 21 may also be fixed to the vehicle body. In either case, the cover body 21 may be fixed to the fixed member directly or indirectly via an intermediate member. In this embodiment, the cover body 21 is attached to the rear end 61 of the second-row lower rail 6 via a mounting bracket 63, which is an intermediate member fastened and fixed by a bolt 62.

[0021] In this embodiment, the cover body 21 is attached to the mounting bracket 63 by a pair of resin fasteners 64. Other fixing members, such as screws, may be used instead of the resin fasteners 64. As shown in FIGS. 2 and 4, the top surface of the cover body 21 is formed with a recess 211 into which a head 641 of the resin fastener 64 fits, and a hole 212 into which a shaft 642 is loosely inserted. Edges 213 and 214 in the front-rear direction of the cover body 21 are portions that cover the ends of the lower rails 6 and 3, respectively. Notches 215 and 216 are formed in the left-right centers of the edges 213 and 214, respectively, to prevent interference with the foot rest 9 of the second-row seat and the foot rest 7 of the third-row seat, which are moving. A stopper 611 and a stopper 311 for restricting the movement of the upper rail 91 and the upper rail 71 are provided near the rear end 61 of the lower rail 6 and the front end 31 of the lower rail 3, respectively.

[0022] The pair of arms 22, 23 hang down from the bottom surface of the cover body 21 so as to extend in the up-down and front-rear directions when attached to the mounting bracket 63. The bottom 24 connects the lower end portions of the arms 22, 23 in the left-right direction, so that the slide rail cover 2 is surrounded by the cover body 21, the pair of arms 22, 23, and the bottom 24, and forms an internal space V2 that communicates with the internal spaces V6 and V3 of the lower rails 6 and 3. The inner surface 24a of the bottom 24 is an inclined surface that slopes upward as it extends forward.

[0023] As described above, the internal space V2 of the slide rail cover 2 is in communication with the internal space V3 of the lower rail 3. Therefore, when a foreign object that has entered the internal space V3 of the lower rail 3 is pushed forward by the upper rail 71, a front portion of the foreign object enters the internal space V2 of the slide rail cover 2.

[0024] Furthermore, the inner surface 24a of the bottom 24 of the slide rail cover 2 is an inclined surface that slopes upward as it moves further forward from the lower rail 3. Therefore, if a foreign object enters the internal space V2, the front end of the foreign object will be raised, preventing it from being pinched from both the front and rear sides and being compressed and crushed. Furthermore, since the foreign object C is less likely to fall downward through the gap S, the foreign object C will not fall downward through the gap S and become impossible to collect.

[0025] In this way, by attaching the slide rail cover 2 to the abutting portion between the rear end 61 of the lower rail 6 and the front end 31 of the lower rail 3, this single component can provide privacy, dust protection, and prevention of foreign objects from falling.

[0026] As shown in Figures 2 and 3, the mounting bracket 63 has a pair of mounting portions 631, a mounting portion 632, and a pair of receiving portions 633. The mounting portion 632 is a plate-shaped portion extending in the left-right and front-rear directions. The pair of mounting portions 631 are portions that extend downward from the left and right edges of the mounting portion 632. The pair of receiving portions 633 are flange-shaped portions that protrude inward and approach each other from the lower tips of the pair of mounting portions 631 (see Figure 3). The mounting portion 631 has an extending portion 6311 that extends forward (see Figure 3). A hole (not shown) is formed in the extending portion 6311, and a bolt is passed through this hole to fasten the mounting bracket 63 to the side wall 6a of the lower rail 6.

[0027] In this way, in the mounting bracket 63, the mounting portion 632 connects the upper ends of the pair of mounting portions 631 in the left-right direction, and the cover main body 21 is placed on the upper surface. The mounting portion 632 is formed with holes 6321 through which the shafts 642 of the pair of resin fasteners 64 are inserted.

[0028] 2, the receiving portion 633 is formed so as to be at approximately the same height as the front end of the inner surface 24a of the bottom portion 24 of the slide rail cover 2. Therefore, the internal space V2 of the slide rail cover 2 and the internal space V63 of the mounting bracket 63 are substantially in communication with each other. This allows the entry of the tip of a foreign object lifted by the inner surface 24a of the bottom portion 24 of the slide rail cover 2 into the mounting bracket 63, and prevents a foreign object pushed forward by the upper rail 71 from being crushed by being pinched between the front and rear ends, even if the foreign object is long in the front-to-rear direction.

[0029] 2, in this embodiment, the cover body 21 of the slide rail cover 2 is fixed to the mounting portion 632 of the attachment bracket 63 by a pair of resin fasteners 64. These fasteners protrude into the internal space V2 of the slide rail cover 2. The holes 212 of the cover body 21 and the holes 6321 of the mounting portion 632 are formed so that the distance in the left-right direction between the shaft portions 642 of the pair of resin fasteners 64 is wider than the groove width of the slide rail.

[0030] Details will be explained with reference to Figure 2. The lower rail 3 has a pair of side walls 310, each with a lower portion that protrudes inward, forming a pair of guide surfaces 313 on which wheels (not shown) of the upper rail 71 roll. The guide surfaces 313 are connected to a horizontal bottom surface 314 via a rising portion 312 that rises from the lower end. Most foreign matter is supported by its own weight when it abuts against the bottom surface 314 from the rising portion 312. The left-right distance between the shaft portions 642 of the pair of resin fasteners 64 is wider than the left-right distance between the pair of rising portions 312. The stoppers 311 of the lower rail 3 are formed by cutting and raising inward from the side walls 310.

[0031] By making the left-right inner width of the shaft portions 642 of the pair of plastic fasteners 64 wider than the left-right spacing between the pair of rising portions 312, foreign matter can be moved through the internal space V3 of the lower rail 3 and the internal space V2 of the slide rail cover 2 so that it also passes through the plastic fasteners 64 in the internal space V63 of the mounting bracket 63.

[0032] The inner width (distance between the inner surfaces in the left-right direction) between the pair of arms 22, 23 of the slide rail cover 2 may be formed so that it is wider on the lower rail 3 side and gradually narrows toward the lower rail 6. That is, the inner surface may be formed so as to slope in a V-shape in plan view. This makes it possible to center the position of a foreign object that has been pushed by the upper rail 71 and entered the internal space V2 of the slide rail cover 2 from the internal space V3 of the lower rail 3 and to adjust its posture.

[0033] 2 and 3, a rail cover 65 and a rail cover 35 are attached to the upper surfaces of the lower rail 6 and the lower rail 3, respectively. The rail covers 65 and 35 are also called finishers and are replaceable.

[0034] 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. 1) are generally horizontal and close the upper opening of the lower rail 3, while the portions that correspond to the upper rail 71 are designed to 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. In this way, the rail cover 35 has the function of fixing the rail cover 35 by being formed so that the end 352 of the rail cover 35 can be pressed down by the slide rail cover 2. The same applies to the rail cover 65.

[0035] 2, the slide rail cover 2 sandwiches the rear end 61 of the rail cover 65 and the front end 31 of the rail cover 35 between the underside of the cover body 21 and the rear end 61 of the lower rail 6 and the front end 31 of the lower rail 3, respectively. In this way, the slide rail cover 2 is a multifunctional member that also has the function of sandwiching the rail covers 35 and 65.

[0036] 1, the rail covers 65, 35 are pressed down by a slide rail cover 15a on the front end 66 side of the lower rail 6, and by a slide rail cover 15 on the rear end 32 side of the lower rail 3, to prevent misalignment. The slide rail cover 15 is mounted on the cover 1 (1L, 1R) having the foreign object discharge port 1a.

[0037] The slide rail cover 2 of the vehicle seat as described above, when attached to the front end 31 of the lower rail 3, not only improves the aesthetic appearance but also performs many functions, such as making it less likely for foreign objects to get caught in the fore-and-aft direction and serving as a mounting member for the rail cover 35.

[0038] The slide rails for the third row of a vehicle M with three rows of seats are often installed so as to hang over the underfloor storage area of the luggage compartment, and the lower rails 3 that make up the slide rails are often exposed when adjusting the seat arrangements. This can lead to foreign objects getting in front of the upper rails 71 in the internal space V3 of the lower rails 3. For this reason, the multifunctional slide rail cover 2 is useful because it has many functions, such as improving the appearance, preventing foreign objects from getting caught, and attaching the rail covers 35, 65, without increasing the number of parts.

[0039] (Second aspect) Next, a slide rail cover 2A for a vehicle seat according to a second aspect of the embodiment of the present invention will be described together with a mounting bracket 63A to which it is attached, with reference to Figures 8 to 11. A slide rail structure including the slide rail cover 2A and the mounting bracket 63A is referred to as a slide rail structure RKA.

[0040] Fig. 8 is a plan view showing the mounting bracket 63A to which the slide rail cover 2A is attached, and Fig. 9 is a plan view showing the slide rail cover 2A attached to the mounting bracket 63A. Fig. 10 is a rear view showing the slide rail cover 2A attached to the mounting bracket 63A. Fig. 11 is a horizontal cross-sectional view of the slide rail structure RKA.

[0041] 8 and 10, the mounting bracket 63A has a connecting portion 63A1, a pair of left and right side standing portions 63A2, an extension arm portion 63A6, and a receiving portion 63A3. The mounting bracket 63A is formed into a generally symmetrical shape by subjecting a metal plate to processes such as punching and bending.

[0042] The side upright portion 63A2 is a portion that extends in the front-rear and up-down directions, and its lower portion is connected to the end of a rectangular connecting portion 63A1 that extends left and right. A female thread portion 63A5 is formed by burring and centered on an axis line CL63 that extends left and right at the front portion of the side upright portion 63A2 on one side in the left-right direction (the right side in this example). Furthermore, a hole 63A7 is formed in the side upright portion 63A2 on the other side (the left side in this example) through which the shank of a bolt 6B (see FIG. 11) is inserted and which threads into the female thread portion 63A5 and centered on the axis line CL63.

[0043] The rear portions of the pair of side uprights 63A2 are formed with extension arms 63A6 that are bent so as to widen to the left and right as they extend rearward. The upper edges of the tips of the extension arms 63A6 are bent outward at 90 degrees to form horizontally extending receiving portions 63A3. Mounting holes 63A4 are formed in the receiving portions 63A3. As shown in FIG. 10, the slide rail cover 2A is attached to the receiving portions 63A3, and fasteners 6F are fitted into the mounting holes 63A4.

[0044] 9 and 10 has a guide portion 2A4 instead of the arm portions 22, 23 and bottom portion 24 of the slide rail cover 2 in the first embodiment. The slide rail cover 2A is made of resin and is formed in a bilaterally symmetrical shape.

[0045] The slide rail cover 2A includes a pair of left and right bases 2A1, a connecting portion 2A2 connecting the pair of bases 2A1, and a frame-like guide portion 2A4 extending downward. The bases 2A1 extend in all directions and have a nearly square shape in plan view. The rear edge of the connecting portion 2A2 is biased forward, making its front-to-back width smaller than that of the bases 2A1. Each of the pair of bases 2A1 is formed with a fixing portion 2A3 having a through hole 2A3a and a circular counterbore portion centered on the through hole 2A3a. The positions of the pair of through holes 2A3a correspond to the positions of a pair of mounting holes 63A4 of the mounting bracket 63A.

[0046] The guide portion 2A4 has a pair of left and right side wall portions 2A41 and a bottom wall portion 2A42 connecting the lower portions of the pair of side wall portions 2A41 to the left and right. The pair of left and right side wall portions 2A41 correspond to the arm portions 22, 23 of the slide rail cover 2. The bottom wall portion 2A42 corresponds to the bottom portion 24 of the slide rail cover 2. The side wall portion 2A41 is a flat wall extending downward from the lower surface of the base portion 2A1 and is formed with a slope that widens outward as it extends rearward. The bottom wall portion 2A42 is formed with a slope that slopes downward as it extends rearward and is divided into three portions depending on the slope direction. That is, a first guide portion 2A44 is a portion in the left-right center, and a pair of second guide portions 2A43 are formed on the left and right of the first guide portion 2A44 and connect to the side wall portion 2A41.

[0047] The first guiding portion 2A44 is not inclined in the left-right direction, but is inclined only in the front-to-rear direction so that the rear portion slopes downward. The left second guiding portion 2A43 is inclined in the front-to-rear direction so that the rear portion slopes downward, and is inclined upward as it extends to the left, connecting to the left side wall portion 2A41. On the other hand, the right second guiding portion 2A43 is inclined in the front-to-rear direction so that the rear portion slopes downward, and is inclined upward as it extends to the right, connecting to the right side wall portion 2A41.

[0048] 9, the slide rail cover 2A described above is attached to the mounting bracket 63A by inserting a fastener 6F into the through-hole 2A3a and a mounting hole 63A4 of the mounting bracket 63A. As a variation of this, a female thread may be formed in the mounting hole 63A4, and a bolt may be used instead of the fastener 6F to screw and fix the slide rail cover 2A to the mounting bracket 63A.

[0049] As shown in Figure 11, the mounting bracket 63A is fixed to the rear of the lower rail 6 of the second-row seats by fastening the side upright portion 63A2 together with the bolt 6B. The slide rail cover 2A fixed to the mounting bracket 63A is designed so that its guide portion 2A4 enters the gap between the lower rail 6 and the lower rail 3 located behind the lower rail 6. In this example, the width of the lower rail 3 is wider than the lower rail 6, and this difference in width is compensated for by the rearward expanding shape of the guide portion 2A4. The internal space V2A of the guide portion 2A4 communicates with the internal space V3A of the lower rail 3 and also with the internal space V6A of the lower rail 6.

[0050] As shown in FIG. 11 , a foreign object C that has fallen into the interior of the lower rail 3 or otherwise entered the interior of the lower rail 3 is pushed by the forward movement of the upper rail 71, which moves to engage with the lower rail 3, and moves to the front of the lower rail 3. At this time, the guide portion 2A4 is interposed between the lower rail 3 and the lower rail 6 so as to fill the gap between the two components, so that the front end of the foreign object C does not, for example, hit the rear end of the lower rail 6 and become pinched between the upper rail 71 and the lower rail 3. Furthermore, the guide portion 2A4 is composed of multiple surfaces that are inclined in the front-rear and left-right directions, namely, a pair of left and right side wall portions 2A41, a first guide portion 2A44, and a pair of second guide portions 2A43. Therefore, the foreign object C that has entered the guide portion 2A4 is guided toward the interior of the lower rail 6. As a result, the slide rail structure RKA is less likely to cause foreign object C to fall further downward through the gap between the lower rail 3 and the lower rail 6, and is extremely less likely to cause problems such as foreign object C getting caught between the upper rail 71 and the rear end of the lower rail 6, or being compressed and damaged while caught.
