Description

  The present invention relates to a vehicle seat mounting structure including a slide rail that slidably supports a vehicle seat back and forth, and a carpet laid under the slide rail.

  For example, many vehicle seats such as a front seat are installed on a slide rail, and a passenger can adjust the position of the seat according to his / her physique. The slide rail is fixed to a floor portion composed of a floor panel or the like mainly by bolt fastening. In this case, the floor is usually covered with an interior material such as a carpet, and the carpet is often interposed between the slide rail and the floor panel.

  For example, in the seat rail portion mounting structure described in Patent Document 1, the carpet is fixed by sandwiching and fixing the carpet between the seat rail (slide rail) and the floor panel. More specifically, the front end of the slide rail is extended, a recess is provided in the floor panel below the extended slide rail, and the carpet is sandwiched in the recess.

Japanese Utility Model Publication No. 6-904

  Although not specified in Patent Document 1, many slide rails are fastened and fixed by inserting bolts into the bolt holes of a floor panel or the like through cutout holes provided in the carpet. However, since the carpet is made of cloth and is a soft material as compared with a floor panel or the like, there is a situation that it is difficult to improve the processing accuracy when the above-described cutout holes are provided and the positioning accuracy when the carpet is laid on the floor. Therefore, there is a possibility that the carpet is installed slightly deviated from the position planned for the floor panel. Even in such a case, the notch hole needs to have a large margin from the beginning and be provided in a wide shape so that the edge of the notch hole is not caught under the bolt to be fastened.

  Incidentally, a general slide rail is composed of a lower rail fixed on the carpet and an upper rail fixed on the lower surface of the seat and moving on the lower rail to slide the seat. The slide rail has a long shape, and in many cases, the lower rail is fixed to the floor panel in the vicinity of the end portion by the above bolt. Therefore, the end portion of the lower rail to be bolted overlaps with the cutout hole of the carpet. Here, the carpet has a function of adjusting the beauty of the interior of the vehicle, and is required to be installed in an orderly manner so as not to cause wrinkles.

  However, since the notch hole is provided in a wide shape with a large margin as described above, the edge of the notch hole easily protrudes around the slide rail and is likely to be wrinkled. In particular, if the edge of the front end of the cutout hole protrudes from the front end of the lower rail and wrinkles are generated there, the upper rail may be caught by the wrinkles when the seat is slid, and the sliding operation may be hindered.

  In view of such a problem, an object of the present invention is to provide a vehicle seat mounting structure that can suppress generation of wrinkles on a carpet with a simple configuration without adding other members.

  In order to solve the above problems, a typical configuration of a vehicle seat mounting structure according to the present invention includes a floor portion of a vehicle having a bolt hole, and a cutout hole that is laid on the surface of the floor portion and overlaps the bolt hole. A vehicle including a carpet, and a long slide rail that is installed on the floor with the carpet interposed therebetween and slidably supports a seat, and has a bolt that is inserted into the bolt hole through the notch hole in the vicinity of the end. In the seat mounting structure for a vehicle, the notch hole has a wide portion that overlaps the bolt hole and is wider than the slide rail, and a tapered portion that tapers from the wide portion toward the end of the slide rail. At least one of the edges is laid under the slide rail.

  If it is the said notch hole, even if it protrudes from the slide rail in the edge part side, since a taper-shaped part is pinched | interposed under the slide rail, an edge will not turn up and a wrinkle will not be caused. Therefore, there is no possibility of hindering the sliding operation of the seat, and it is possible to keep the aesthetic appearance in the passenger compartment.

  The slide rail is provided on either side of the lower surface of the seat in the vehicle width direction so as to extend in the vehicle front-rear direction. Of the tapered portion, the edge of the seat center side in the vehicle width direction is more than the edge of the seat outer side. It should be tapered with a large gradient. For example, by positioning the slide rail so as to match the outer edge of the wide seat in the cutout hole, first, the outer edge (outer edge) of the tapered portion can be securely sandwiched by the slide rail. On the other hand, the inner edge of the taper-shaped seat (inner edge) is also tapered with a larger gradient than the outer edge, so that this inner edge absorbs misalignment regardless of the positional relationship with the slide rail. And can be sandwiched by slide rail at any point. Furthermore, even if the floor is exposed from the inner edge side due to the position shift, it is a place that is difficult to see inside the seat, which is convenient in terms of aesthetics.

  The wide part may have a rectangular shape, and the tapered part may have a trapezoidal shape. Also with this configuration, it is possible to prevent wrinkles from occurring at the edge of the notch hole by sandwiching the tapered portion with the slide rail.

  The notch hole is preferably provided in the carpet so that the bolt hole is located at the center of the wide portion. The notch hole is a part formed with a margin so that the edge is not caught in the bolt fastening, and it is preferable that the notch hole is provided based on the position where the bolt hole comes to the center of the wide part as described above.

  According to the said structure, it becomes possible to provide the vehicle seat attachment structure which can suppress generation | occurrence | production of the wrinkle etc. to a carpet with the simple structure which does not add a member.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are not illustrated. To do.

  FIG. 1 is a diagram showing an outline of a vehicle seat mounting structure according to an embodiment of the present invention. The vehicle seat mounting structure (hereinafter referred to as mounting structure 100) shown in FIG. 1 is intended for a front right seat of a vehicle, and a light truck is assumed as an applied vehicle. In light trucks, an engine (not shown) is located below the seat 104, and the floor panel 106 below the seat 104 is often raised one step as shown in the figure. The mounting structure 100 described below can suppress wrinkles and the like of the carpet 108, and the effect can be exhibited particularly effectively in a light truck.

  In the mounting structure 100, the floor is composed of a floor panel 106 and a riser panel 110 covered with a carpet 108. FIG. 2 is an exploded view of the vicinity of the riser panel 110 of FIG. The riser panel 110 is a part that becomes a floor below the seat 104 (see FIG. 1). The riser panel 110 is installed on the floor panel 106 (see FIG. 1) by hinge portions 114a and 114b of the two slide rails 112a and 112b so as to be openable and closable, and also serves as a lid for the opening 116 of the floor panel 106. When the vehicle is being maintained, the engine panel (not shown) can be easily operated by opening the riser panel 110.

  A carpet 108 is laid on the surface of the riser panel 110, and slide rails 112a and 112b are installed thereon. The slide rails 112a and 112b are portions that support the seat 104 (see FIG. 1) in a slidable manner and have a long shape. Taking the slide rail 112a as an example, the slide rail 112a includes a lower rail 118a fixed to the riser panel 110 and an upper rail 118b fixed to the seat 104. The slide rails 112a and 112b are provided to one seat 104 so as to extend in the vehicle front-rear direction on both ends of the lower surface of the seat 104 in the vehicle width direction.

  A bolt 120 (see FIG. 4) is used in the vicinity of the front end 130 of the slide rail 112a, and the bolt 120 is fixed by being inserted into the bolt hole 122a of the riser panel 110 (the slide rail 112b is not shown). The bolt is fastened and fixed to the bolt hole 122b). At that time, the carpet 108 is provided with notches 124a and 124b, and the bolts are fastened to the riser panel 110 through the notches 124a and 124b. The cutout holes 124a and 124b are provided at positions overlapping the bolt holes 122a and 122b in the carpet 108.

  FIG. 3 is a schematic diagram of the carpet 108 of FIG. FIG. 3A shows the entire carpet 108 as viewed from above. As shown in FIG. 3A, the notch holes 124a and 124b have bolt holes 122a and 112b of the riser panel 110 of FIG. 2 so that the edges thereof are not caught in the fastening of the bolt 120 (see FIG. 4A). It is provided larger than. If the cutout holes 124a and 124b are thus provided in large sizes, the edges may protrude from the slide rail 112a (see FIG. 2) and wrinkles may occur. However, in this embodiment, the shape of the cutout holes 124a and 124b is devised. This reduces wrinkles.

  FIG.3 (b) is an enlarged view of the notch hole 124a of Fig.3 (a). The cutout holes 124a are formed in a polygonal shape as a whole, and are roughly composed of a wide portion 126 and a tapered portion 128. The wide portion 126 is a rectangular portion that mainly overlaps the bolt hole 122a (see FIG. 2), and is provided with a large margin so that the edge thereof is not caught in the bolt fastening. It is preferable to provide the wide portion 126 so that the bolt hole 122a comes to the center P1 because an error is easily allowed when an error occurs in the installation position of the carpet 108.

  The tapered portion 128 is provided on the vehicle front side of the wide portion 126 (the front end 130 side of the slide rail 112a). The original role of the tapered portion 128 is a portion provided as so-called “play” so that an error can be allowed if an error occurs in the installation position of the carpet 108. However, in the present embodiment, a trapezoidal shape is provided so as to taper toward the front side of the vehicle in order to suppress the occurrence of wrinkles on the carpet 108 described later.

  4 is a view in which the slide rail 112a of FIG. 2 is attached on the carpet 108 of FIG. In FIG. 4, only the lower rail 118a is illustrated as the slide rail 112a. As shown in FIG. 4, the wide portion 126 is provided with a margin so as to be wider than the slide rail 112a. The tapered portion 128 is tapered, and in particular, the inner edge 132 thereof is sandwiched between the slide rail 112a and the riser panel 110 (see FIG. 2).

  FIG. 5 is a view showing the vehicle seat mounting structure and a vehicle seat mounting structure which is a comparative example thereof. In the vehicle seat mounting structure (hereinafter referred to as mounting structure 10) shown in FIG. 5 (b), the notch hole 20 is provided in a simple rectangle as a whole as shown by a broken line, and a tapered portion 128 (FIG. 5 (a)). There is no reference). With this shape, when the front edge 30 of the cutout hole 20 is positioned in front of the slide rail 112a, the front edge 30 may be lifted from the riser panel 110. If such a lift occurs, when the seat 104 (see FIG. 1) is slid, the upper rail 118b is caught on the front edge 30 and the sliding motion may be obstructed, or the front edge 30 may be wrinkled. There is a risk of damaging the aesthetics.

  On the other hand, the mounting structure 100 shown in FIG. 5A is configured such that the inner edge 132 of the tapered portion 128 is laid under the slide rail 112a. As a result, even if the front edge 136 of the cutout hole 124a protrudes from the front end 130 of the slide rail 112a, the front edge 136 does not turn up. Therefore, there is no possibility of obstructing the sliding operation of the upper rail 118b, and there is no possibility of wrinkling. In this manner, in the mounting structure 100, it is possible to suppress the occurrence of wrinkles and the like of the carpet 108 with a simple configuration in which no member is added.

  As illustrated in FIG. 3B, in the present embodiment, of the edges of the tapered portion 128, the inner edge 132 located on the center side of the seat 104 in the vehicle width direction is larger than the outer outer edge 134. Tapered with a gradient. The slide rail 112a shown in FIG. 4 may be positioned in accordance with the outer edge of the wide portion 126 of the vehicle. With this configuration, the outer edge 134 can be securely sandwiched by the slide rail 112a. Therefore, the outer edge 134 may have a tapered shape with a small gradient. On the other hand, by forming the inner edge 132 in a tapered shape having a large gradient, the inner edge 132 can be sandwiched between the slide rails 112a at any position regardless of the positional relationship with the slide rails 112a. That is, the inner edge 132 has a large gradient and can absorb a positional deviation from the slide rail 112a. In addition, if a displacement occurs, the riser panel 110 (see FIG. 2) is likely to be exposed from the cutout hole 124a on the inner edge 132 side. However, since the inner edge 132 is located in an invisible place inside the seat, Convenient in terms. The edge sandwiched between the slide rails 112a may be either the inner edge 132 or the outer edge 134.

(Modification)
FIG. 6 is a view showing a modification of the cutout holes 124a and 124b in FIG. As shown in FIG. 6A, the cutout holes 200a and 200b are provided in an elliptical shape. In particular, as shown in an enlarged view in FIG. 6B, the cutout holes 200 a and 200 b are not mere ellipses, but are configured to taper toward the front. In particular, the inner edge 202 tapers with a larger gradient than the outer edge 204. It is good to have. Even with such cutout holes 200a and 200b, the inner edge 202 can be sandwiched by the slide rail 112a (see FIG. 5A), and the occurrence of wrinkles and the like of the carpet 108 can be efficiently suppressed. become. Further, since the cutout holes 200a and 200b do not have corner portions, it is possible to prevent tearing that is likely to occur from the corner portions.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
