[0001] The present invention relates to a vehicle floor structure.

Background Art

[0002] It is common practice to lay a floor mat on the floor of a vehicle such as an automobile. Also, it is common practice to provide a seat rail on the vehicle floor for supporting and guiding a vehicle seat. When a seat rail is provided on the vehicle floor, for the convenience of supporting and guiding the vehicle seat by the seat rail, the floor mat is provided so as not to cover the upper part of the seat rail (see, for example, Patent Document 1).

[0003] In the vehicle floor structure described in Patent Document 1, a locking member is provided at a portion of the end of the floor mat that faces the seat rail in the vehicle width direction. This locking member is structured to be locked to the seat rail by moving so as to be close to the seat rail when the floor mat is attached. In the above vehicle floor structure, by locking the locking member to the slide rail, the floor mat is attached around the slide rail so as not to cover the upper part of the slide rail.

[0004] Also, in the above vehicle floor structure, the floor mat has a portion (hereinafter referred to as the inter-rail portion) disposed between two adjacent seat rails. Locking members are provided at both ends in the vehicle width direction, which is the arrangement direction of the two seat rails, in the inter-rail portion. By locking these locking members to the opposing seat rails respectively, the inter-rail portion of the floor mat is attached between two adjacent seat rails.

Summary of the Invention

[0006] Normally, when a floor mat is installed on a vehicle floor with seat rails, the portion of the floor mat between the rails is positioned so that it fits snugly between two adjacent seat rails without any gaps. Therefore, in the above-mentioned vehicle floor structure, the process of positioning the portion between the rails between the two seat rails is carried out in a way that involves locking the locking members at both ends in the vehicle width direction to the opposing seat rails, while there is no extra space in the vehicle width direction. This process is difficult and complicated, and in this respect, the above-mentioned vehicle floor structure has room for improvement. [Means for solving the problem]

[0007] The following describes various embodiments of the apparatus for solving the above problems. [Aspect 1] A vehicle floor structure comprising: a floor body; a plurality of seat rails provided on the floor body so as to extend in a first direction and for supporting a vehicle seat so as to be slidable in the first direction; a floor mat provided so as to cover the upper surface of the floor body and including a portion between rails positioned between two adjacent seat rails; and locking portions provided at both ends of the portion between rails in a second direction intersecting the first direction, which are locked to the seat rails by moving in the second direction so as to approach the opposing seat rails, wherein the portion between rails has a bent portion extending in the first direction, and the bent portion is configured to allow the portion between rails to bend in the second direction.

[0008] According to the above configuration, when installing the floor mat, the rail-to-rail portion of the floor mat can be bent in a second direction at the bending point, causing it to fold upwards. In this state, by positioning the rail-to-rail portion between the two seat rails, it becomes possible to position the locking parts at both ends of the rail-to-rail portion so that they are away from the seat rails but facing them, while leaving ample space in the second direction. Subsequently, while maintaining the opposing state between the locking parts and the seat rails in the second direction, the bending point is extended in the second direction, returning the rail-to-rail portion to its state before bending, thereby moving the locking parts closer to the seat rails in the second direction. As a result, each of the locking parts at both ends of the rail-to-rail portion can be locked to the opposing seat rails, allowing the rail-to-rail portion of the floor mat to fit snugly between the two seat rails without any gaps.

[0009] According to the above configuration, a floor mat that does not have sufficient space in the second direction when installed can be easily placed on the floor of a vehicle with seat rails by bending and extending the portion between the rails at the bending point.

[0010] [Aspect 2] The vehicle floor structure according to [Aspect 1], wherein the floor mat has a structure in which a base portion that constitutes the lower part and a mat portion that constitutes the upper part above the base portion and is softer than the base portion are superimposed, and the bent portion is provided on the base portion.

[0011] In the above configuration, the bending section for folding the rail section is provided in the relatively rigid base section of the floor mat, which is part of the mat section that makes up the upper part of the floor mat and the base section that makes up the lower part. This makes it possible to easily bend the relatively rigid base section, and therefore the entire floor mat, including the base section, can be easily folded.

[0012] [Aspect 3] The vehicle floor structure according to [Aspect 1] or [Aspect 2], wherein the bent portion is composed of a groove that opens on the lower surface of the floor mat, and the cross-sectional shape of the groove is tapered, becoming narrower as it approaches the upper surface of the floor mat.

[0013] According to the above configuration, the section between the rails can be bent at the bend by deforming the section between the rails so as to narrow the width of the groove, with the bottom of the groove constituting the bend as the pivot point. Alternatively, the section between the rails can be extended at the bend by deforming the section between the rails so as to widen the groove, with the bottom of the groove constituting the bend as the pivot point.

[0014] In the above configuration, the wider the groove, the greater the allowable bending angle between the rails. However, widening the groove tends to reduce the strength of the upper part of the floor mat, making it easier for recessed and protruding areas to appear on the top surface of the floor mat.

[0015] With the above configuration, the width of the groove can be narrowed in the upper part of the floor mat where a decrease in strength is a concern. This suppresses the decrease in strength of the upper part of the floor mat, thereby suppressing the deterioration in appearance caused by the appearance of recessed or protruding parts. Moreover, the width of the groove can be widened in the lower part of the floor mat. This allows for a larger amount of deformation, i.e., a larger bending angle, when deforming the section between the rails to narrow the width of the groove in order to bend the section between the rails. [Effects of the Invention]

[0016] According to the present invention, a floor mat can be easily placed on the floor of a vehicle having seat rails. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0018] Hereinafter, the vehicle floor structure of one embodiment will be described with reference to FIGS. 1 to 7. Hereinafter, the front-rear direction, vehicle width direction, and up-down direction of the vehicle will be simply described as the "front-rear direction X", "vehicle width direction Y", and "up-down direction Z", respectively. Also, the front and rear in the front-rear direction X will be simply described as "front" and "rear", respectively. Also, the upper and lower in the up-down direction Z will be simply described as "upper" and "lower", respectively.

[0019] <Floor main body> As shown in FIGS. 1 and 2, the vehicle to which the vehicle floor structure of the present embodiment is applied includes a floor main body 10. The floor main body 10 is a part that forms the base of the vehicle floor and extends in the front-rear direction X and the vehicle width direction Y.

[0020] <Seat rail> Multiple seat rails 20 are provided on the floor body 10. Note that only two seat rails 20 are shown in Figures 1 and 2. The seat rails 20 support a vehicle seat (not shown) so that it can slide in the front-rear direction X. As shown in Figures 1 to 3, the seat rail 20 has a rail portion 21, an end cap 22, and a rail-side locking member 23.

[0021] The rail section 21 extends linearly in the longitudinal direction X. In this embodiment, the longitudinal direction X corresponds to the first direction. As shown in Figures 2 and 3, the rail section 21 has a pair of side walls 211 spaced apart in the vehicle width direction Y and a bottom wall 212 connecting the lower ends of the side walls 211. The rail section 21 has an opening 213 in the central part in the vehicle width direction Y that opens upward. The opening 213 extends in the longitudinal direction X. In this embodiment, the lower part of a vehicle seat (not shown) is connected to the rail section 21 via the opening 213. The vehicle seat is supported and guided by this rail section 21.

[0022] As shown in Figure 1, the end caps 22 are provided at both ends of the rail section 21 in the front-rear direction X. The end caps 22 are provided so as to cover the upper part of the rail section 21. The end caps 22 protect the ends of the rail section 21 in the front-rear direction X.

[0023] <Rail-side locking member 23> As shown in Figures 2 and 3, the rail-side locking member 23 has a substantially T-shaped cross-section and extends in the front-rear direction X along the rail portion 21. The rail-side locking member 23 is fixed to the rail portion 21. As shown in Figure 3, the rail-side locking member 23 includes a fixing portion 231 and a locking piece 232.

[0024] The fixing portion 231 is used to fix the rail-side locking member 23 to the rail portion 21. The fixing portion 231 is composed of the portion of the rail-side locking member 23 that is on the rail portion 21 side, which has a roughly T-shaped cross-section, and more specifically, the portion that has a roughly L-shaped cross-section. The fixing portion 231 is fixed to the end of the rail portion 21 in the vehicle width direction Y. In this way, the rail-side locking member 23 is fixed to the rail portion 21.

[0025] The locking piece 232 is the part used to attach the floor mat 30, which will be described later, to the rail portion 21. The locking piece 232 is composed of the portion of the rail-side locking member 23, which has a roughly T-shaped cross-section, that is furthest from the rail portion 21, more specifically, the portion that has a roughly I-shaped cross-section. The locking piece 232 has a canopy-like shape that protrudes in the vehicle width direction Y from the upper end of the fixing portion 231.

[0026] <Floor Mat 30> As shown in Figures 1 to 4, a vehicle to which the vehicle floor structure of this embodiment is applied is equipped with a floor mat 30. The floor mat 30 is provided so as to cover the upper surface of the floor body 10. As shown in Figures 2 and 3, the floor mat 30 has a mat body 31. The mat body 31 includes a base portion 32 and a mat portion 33. Both the base portion 32 and the mat portion 33 are plate-shaped and extend in the longitudinal direction X and the vehicle width direction Y. The mat body 31 has a structure in which the base portion 32 and the mat portion 33 are superimposed in the vertical direction Z.

[0027] The base portion 32 constitutes the lower part of the floor mat 30. The base portion 32 constitutes the part of the floor mat 30 that is supported by the floor body 10, and also constitutes the part that supports the mat portion 33 from below. The base portion 32 is made of a soft resin material such as soft polyurethane foam.

[0028] The mat portion 33 constitutes the upper part of the floor mat 30. The upper surface of the mat portion 33 constitutes the floor surface of the vehicle floor. The mat portion 33 is made of a soft resin material such as soft polyvinyl chloride. In this embodiment, the mat portion 33 is softer than the base portion 32. The outer edge of the mat portion 33 is provided with a reinforcing portion 34 to reinforce the outer edge.

[0029] As shown in Figures 1 and 4, the floor mat 30 is composed of a portion positioned between two adjacent seat rails 20 (hereinafter referred to as the inter-rail portion 30A) and a portion other than the inter-rail portion 30A (hereinafter referred to as the other portion 30B). The inter-rail portion 30A constitutes the rear portion of the floor mat 30. The inter-rail portion 30A has a roughly rectangular shape in plan view. The other portion 30B constitutes the front portion of the floor mat 30, more specifically the portion in front of the seat rails 20.

[0030] <Mat-side locking member 35> As shown in Figures 2 and 3, the floor mat 30 has a mat-side locking member 35. The mat-side locking member 35 is used when attaching the floor mat 30 to the rail portion 21. In this embodiment, the mat-side locking member 35 corresponds to the locking portion that locks to the seat rail 20.

[0031] The mat-side locking members 35 are provided at both ends in the vehicle width direction Y of the rail-to-rail portion 30A of the floor mat 30. As shown in Figure 3, the mat-side locking members 35 include a fixing portion 351 and a fitting portion 352. The fixing portion 351 and the fitting portion 352 are integrally formed from a resin material. In this embodiment, the vehicle width direction Y corresponds to a second direction intersecting the first direction.

[0032] The fixing portion 351 is the part used to fix the mat-side locking member 35 to the mat body 31. The fixing portion 351 is plate-shaped and extends in the front-rear direction X and the vehicle width direction Y. The fixing portion 351 constitutes the part of the mat-side locking member 35 that is farther from the seat rail 20. At the end of the rail-to-rail portion 30A on the seat rail 20 side, the fixing portion 351 is fixed to the mat body 31 by being sandwiched between the mat portion 33 and the base portion 32 that make up the mat body 31. By fixing the fixing portion 351 to the mat body 31 in this way, the mat-side locking member 35 is fixed to the floor mat 30, more specifically to the mat body 31.

[0033] The fitting portion 352 is the part into which the locking piece 232 of the rail-side locking member 23 fits when the floor mat 30 is installed in the vehicle. The fitting portion 352 constitutes the part of the mat-side locking member 35 that is closer to the seat rail 20. The fitting portion 352 has a substantially U-shaped cross-section and extends in the front-rear direction X. The fitting portion 352 opens toward the opposing seat rail 20. In this embodiment, when the floor mat 30 is installed in the vehicle, the locking piece 232 of the rail-side locking member 23 enters the interior of the fitting portion 352 of the mat-side locking member 35 through the opening of the fitting portion 352 and fits into it.

[0034] <Bent section 36> As shown in Figures 1, 2, and 4, the floor mat 30 has a bent portion 36. The bent portion 36 is provided on the base portion 32. The bent portion 36 extends in the longitudinal direction X at a position corresponding to the center of the vehicle width direction Y on the base portion 32. The bent portion 36 extends continuously from the front end to the rear end of the base portion 32. As shown in Figure 2, the bent portion 36 is composed of a groove that opens on the lower surface of the base portion 32. The cross-sectional shape of the groove constituting the bent portion 36 is tapered, becoming narrower as it approaches the upper surface of the floor mat 30. More specifically, the cross-sectional shape of the inner surface of the groove constituting the bent portion 36 is V-shaped.

[0035] In this embodiment, the floor mat 30 including the rail-to-rail portion 30A is configured to bend in the vehicle width direction Y at the bent portion 36. Specifically, as shown by the solid line in Figure 5, by deforming the floor mat 30 so as to narrow the width of the groove that constitutes the bent portion 36, with the bottom 37 of the groove as the pivot point, the floor mat 30 can be folded at the bent portion 36 as indicated by arrow M1 in the figure. Also, as shown by the dashed line in Figure 5, by deforming the floor mat 30 so as to widen the width of the groove that constitutes the bent portion 36, with the bottom 37 of the groove as the pivot point, the floor mat 30 can be stretched at the bent portion 36 as indicated by arrow M2 in the figure.

[0036] <Operation of this embodiment> The following describes the procedure for installing the floor mat 30 so as to cover the upper surface of the floor unit 10.

[0037] As shown in Figure 6, when installing the floor mat 30 in the vehicle, first, the floor mat 30 is bent in the vehicle width direction Y at the bending portion 36, so that the floor mat 30 is folded so that it is convex upwards. In this state, the floor mat 30 is placed on the floor body 10 such that the rail-interval portion 30A of the floor mat 30 is positioned between the two seat rails 20. As a result, with ample space in the vehicle width direction Y, each of the mat-side locking members 35 provided at both ends of the rail-interval portion 30A is positioned away from the rail-side locking members 23 of the seat rails 20 and facing the rail-side locking members 23.

[0038] Here, if the mat body 31 is not provided with a bending portion 36, then when the floor mat 30 is bent in the vehicle width direction Y, the floor mat 30 will be in a curved state in the vehicle width direction Y. In this case, the angle (indicated as "AL" in Figure 5) between the end of the floor mat 30 in the vehicle width direction Y and the surface extending in the front-rear direction X and the vehicle width direction (hereinafter referred to as the horizontal plane H) becomes larger compared to the case where the floor mat 30 is in a curved state in the vehicle width direction Y. Therefore, in this case, the difference (corresponding to the above angle AL) between the attitude angle of the mat-side locking members 35 provided at both ends of the rail-to-rail portion 30A and the attitude angle of the rail-side locking members 23 provided on the seat rail 20 becomes larger. As a result, when installing the floor mat 30, it becomes difficult to fit the locking piece 232 of the rail-side locking member 23 into the fitting portion 352 of the mat-side locking member 35.

[0039] In this embodiment, since the mat body 31 is provided with a bent portion 36, the floor mat 30 can be folded at this bent portion 36 so as to bend in the vehicle width direction Y. Therefore, compared to the case where the bent portion 36 is not provided, the angle AL can be made smaller, and the angle difference between the attitude angle of the mat-side locking member 35 and the attitude angle of the rail-side locking member 23 (corresponding to the angle AL in this embodiment) can be made smaller. As a result, the locking piece 232 of the rail-side locking member 23 can easily enter the fitting portion 352 of the mat-side locking member 35, so that the locking piece 232 can be easily fitted into the fitting portion 352.

[0040] Subsequently, as shown in Figures 2 and 7, the floor mat 30 is returned to its pre-folded state by extending the bent portion 36 in the vehicle width direction Y, while maintaining the state in which the fitting portion 352 of the mat-side locking member 35 and the locking piece 232 of the rail-side locking member 23 face each other in the vehicle width direction Y. At this time, as indicated by arrow M3 in Figure 7, the mat-side locking member 35 moves in the vehicle width direction Y so as to approach the rail-side locking member 23. Then, the locking pieces 232 of the rail-side locking member 23 provided on the opposing seat rail 20 enter into each of the fitting portions 352 of the mat-side locking member 35 provided at both ends of the rail-to-rail portion 30A. After that, as shown in Figure 2, the locking pieces 232 of the rail-side locking member 23 of the opposing seat rail 20 fit into each of the fitting portions 352 of the mat-side locking member 35. In this embodiment, the rail-side locking members 23 of the opposing seat rails 20 are locked to each of the mat-side locking members 35 at both ends of the rail-interval portion 30A. As a result, the rail-interval portion 30A of the floor mat 30 is positioned to fit snugly between the two seat rails 20 without any gaps.

[0041] According to this embodiment, the floor mat 30, which does not have sufficient space in the vehicle width direction Y when installed, can be easily placed on the vehicle floor having the seat rail 20 by bending and straightening it at the bending portion 36.

[0042] <Effects of this embodiment> The effects of this embodiment will now be explained. (1) The vehicle floor structure comprises a floor body 10, a plurality of seat rails 20, a floor mat 30, and a mat-side locking member 35. The seat rails 20 are provided on the floor body 10 so as to extend in the longitudinal direction X, and support the vehicle seat so as to be slidable in the longitudinal direction X. The floor mat 30 is provided so as to cover the upper surface of the floor body 10 and includes a rail-interval portion 30A positioned between two adjacent seat rails 20. The mat-side locking member 35 is provided at both ends of the rail-interval portion 30A in the vehicle width direction Y, and locks onto the seat rails 20 by moving in the vehicle width direction Y to approach the opposing seat rail 20. The floor mat 30 including the rail-interval portion 30A has a bent portion 36 extending in the longitudinal direction X. The bent portion 36 is configured to allow the floor mat 30 to bend in the vehicle width direction Y.

[0043] According to the above configuration, the floor mat 30 can be easily placed on the floor of a vehicle having a seat rail 20. (2) The floor mat 30 has a structure in which a base portion 32 that constitutes the lower part and a mat portion 33 that constitutes the upper part above the base portion 32 are superimposed. The mat portion 33 is softer than the base portion 32. The bending portion 36 is provided in the base portion 32.

[0044] According to the above configuration, the bending portion 36 for folding the floor mat 30 can be provided in the relatively rigid base portion 32 of the floor mat 30, which consists of the mat portion 33 that constitutes the upper part of the floor mat 30 and the base portion 32 that constitutes the lower part. As a result, the relatively rigid base portion 32 can be easily bent, and therefore the entire floor mat 30, including the base portion 32, can be easily folded.

[0045] (3) The bent portion 36 is formed by a groove that opens on the lower surface of the floor mat 30, more specifically on the lower surface of the base portion 32. The cross-sectional shape of the groove that constitutes the bent portion 36 is tapered, becoming narrower as it approaches the upper surface of the floor mat 30.

[0046] With the above configuration, the floor mat 30 can be folded at the bent portion 36 by deforming it so as to narrow the width of the groove, using the bottom 37 of the groove that constitutes the bent portion 36 as a fulcrum. Alternatively, the floor mat 30 can be stretched at the bent portion 36 by deforming it so as to widen the width of the groove, using the bottom 37 of the groove that constitutes the bent portion 36 as a fulcrum.

[0047] In the above configuration, the wider the groove, the greater the bending angle that the floor mat 30 can be allowed to bend. However, widening the groove tends to reduce the strength of the upper part of the floor mat 30, making it easier for recessed or protruding parts to appear on the upper surface of the floor mat 30.

[0048] According to the above configuration, the cross-sectional shape of the groove is tapered, becoming narrower as it approaches the top surface of the floor mat 30. Therefore, the width of the groove can be narrowed in the upper part of the floor mat 30 where a decrease in strength is a concern. This suppresses the decrease in strength in the upper part of the floor mat 30, making it less likely for recessed or protruding parts to appear on the top surface of the floor mat 30. Consequently, the deterioration of the appearance of the floor mat 30 due to recessed or protruding parts can be suppressed. Moreover, the width of the groove can be widened in the lower part of the floor mat 30. This allows for a larger amount of deformation, specifically a larger bending angle, when the floor mat 30 is deformed to narrow the width of the groove in order to fold it.

[0049] <Example of changes> The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0050] The plan view shape and arrangement of the other portion 30B of the floor mat 30, which is the portion other than the rail-to-rail portion 30A, can be arbitrarily changed. For example, the outer edge of the other portion 30B may be shaped to extend along the inner wall of the passenger compartment. In addition, the other portion 30B can be provided in a part other than the front of the rail-to-rail portion 30A, such as the rear side of the rail-to-rail portion 30A.

[0051] The other portion 30B of the floor mat 30, which is the portion between the rails 30A, can be omitted. The floor mat 30 may be composed only of the portion between the rails 30A.

[0052] The structure of the rail-side locking member 23 can be arbitrarily changed as long as it is a structure that can fix the rail-side locking member 23 to the rail section 21 and can lock the mat-side locking member 35 with the rail-side locking member 23.

[0053] The rail-side locking member 23 may be omitted, and the end of the seat rail 20 on the mat body 31 side may be formed in a shape that allows it to be locked to the mat-side locking member 35. The structure of the mat-side locking member 35 can be arbitrarily changed. The structure of the mat-side locking member 35 only needs to be such that it can be fixed to the mat body 31, and that it can be locked to the rail-side locking member 23 of the seat rail 20 by moving in the vehicle width direction Y so as to be close to the opposing seat rail 20.

[0054] The mat-side locking member 35 may be omitted, and the end of the mat body 31 on the seat rail 20 side may be formed in a shape that can be locked to the mat-side locking member 35. In this case, the end of the mat body 31 on the seat rail 20 side corresponds to the locking portion.

[0055] The floor mat 30 may be provided with multiple bent sections 36. Figures 8 and 9 show an example of such a floor mat 40. In the example shown in Figures 8 and 9, the floor mat 40 is provided with three bent sections 46.

[0056] As shown in Figures 8 and 9, the three bent sections 46 all extend in the longitudinal direction X and extend parallel to each other at intervals in the vehicle width direction Y. By providing the three bent sections 46, the floor mat 40 can be folded as shown in Figure 9. Specifically, at the central bent section 46 in the vehicle width direction Y (hereinafter referred to as the first bent section 461) of the three bent sections 46, the floor mat 40 can be deformed so as to narrow the width of the groove that constitutes the first bent section 461, with the bottom of the groove as the pivot point. As a result, at the first bent section 461, the floor mat 40 is folded so as to become convex upwards. On the other hand, at the remaining two bent sections 46 of the three bent sections 46 (hereinafter referred to as the second bent sections 462), the floor mat 40 can be deformed so as to widen the width of the groove that constitutes the second bent section 462, with the bottom of the groove as the pivot point. As a result, at the second bent section 462, the floor mat 40 is folded so as to become convex downwards.

[0057] By folding the floor mat 40 in this manner, as is clear from Figure 9, the angle AL between the end of the floor mat 40 in the vehicle width direction Y and the horizontal plane H can be reduced compared to the case where only one bent portion 36 is provided (see Figure 5). This makes it easier for the locking piece 232 of the rail-side locking member 23 (see Figure 3) to enter the fitting portion 352 of the mat-side locking member 35, so that the locking piece 232 can be easily fitted into the fitting portion 352.

[0058] The bent portion 36 is not limited to being provided to extend continuously from the front end to the rear end of the base portion 32, but may be provided to extend in any manner. For example, the bent portion 36 may be provided to extend intermittently in the front-rear direction X, or only in the intermediate portion between the front end and the rear end of the base portion 32, or only in the portion of the base portion 32 corresponding to the rail-to-rail portion 30A.

[0059] The cross-sectional shape of the grooves constituting the bent portion 36 can be arbitrarily changed. For example, the grooves constituting the bent portion 36 can be formed so that the cross-sectional shape of the inner surface of the grooves is U-shaped. In addition, it is also possible to make the cross-sectional shape of the grooves constituting the bent portion 36 roughly I-shaped.

[0060] The bent portion 36 can be realized using a configuration other than a groove opening on the underside of the floor mat 30. For example, the bent portion 36 can be realized by forming it from a resin material that is softer than the surrounding area (for example, a mesh foam sponge made of soft urethane foam). Alternatively, the mat body 31 can be divided in the vehicle width direction Y, and the bent portion 36 can be realized by connecting the divided parts via hinges. With such a configuration, the floor mat 30 can be folded at the bent portion 36 so as to bend in the vehicle width direction Y.

[0061] The mat portion 33 may be formed from a soft resin material, or it may be formed from a woven fabric, nonwoven fabric, or rubber material. The base portion 32 may be formed from nonwoven fabric or rubber material.

[0062] The mat body 31 may be constructed from a single plate-like member instead of having a structure in which the base portion 32 and the mat portion 33 are superimposed. The mat body 31 may also be constructed from a structure in which three or more plate-like members are superimposed in the vertical direction Z.

[0063] The vehicle floor structure according to the above embodiment can also be applied to vehicles in which the seat rails 20 are provided on the floor body 10 so as to extend in a direction other than the longitudinal direction X. For example, the vehicle floor structure according to the above embodiment can be applied to vehicles in which the seat rails 20 are provided on the floor body 10 so as to extend in the vehicle width direction Y. In this vehicle floor structure, the vehicle width direction Y corresponds to a first direction, and the longitudinal direction X corresponds to a second direction that intersects the first direction.
