Description

Technical Field

[0001] The present invention relates to a vehicle floor structure having a front row seat that can be bounced from a seating position to a bouncing position.

Background Art

[0002] Patent Document 1 includes a front row seat in which left and right seats can be bounced from a seating position to a bouncing position around a front rotation axis, and a rear row seat disposed behind the vehicle, and a plurality of gussets that protrude upward are provided at intervals in the vehicle left-right direction, thereby disclosing a floor structure capable of securing a footrest space for a passenger sitting in the rear row seat between adjacent gussets.

[0003] However, the technology disclosed in the above publication has the following problems. (i) Since the floor surface between adjacent gussets is flat, the footrest position of the rear seat passenger is not restricted in the vehicle front-rear direction. Therefore, when the rear seat passenger places their feet forward of the vehicle between adjacent gussets, there is a risk that the front row seat will interfere with the feet when the front row seat is returned from the bouncing position to the seating position. (ii) In order to secure a footrest space for the rear seat passenger in the vertical direction so that the front row seat does not interfere with the feet, the height of the gusset from the floor surface must be set relatively high, and for this reason, it is necessary to lower the floor surface. Therefore, it may be difficult to secure a mounting space for underfloor components such as a fuel tank, an exhaust pipe, a battery mounted on a BEV (Battery Electric Vehicle) or a HEV (Hybrid Electric Vehicle).

Summary of the Invention

Problems to be Solved by the Invention

[0005] The object of the present invention is to provide a vehicle interior floor structure that can suppress interference between the front seats and the legs, and facilitate the securing of space for mounting underfloor components, at least one of the above. [Means for solving the problem]

[0006] The present invention, which achieves the above objective, is as follows. (1) Front seats that can be folded up from the seated position to the folded-up position, Rear seats are positioned behind the front seats of the vehicle, A striker is provided on the floor of the passenger compartment and engages when the front seats are in the seated position, A resin cover is provided around the striker and fixed to the floor, It has, The aforementioned striker comprises a right striker and a left striker located to the left of the vehicle relative to the right striker. The cover comprises a right cover disposed around the right striker and a left cover disposed around the left striker. A passenger compartment floor structure in which a convex portion extending in the left-right direction of the vehicle is provided on the floor portion located between the right cover and the left cover, with the convex portion extending upward. (2) The cover further has a cover connecting portion that extends in the left-right direction of the vehicle between the right cover and the left cover and connects the right cover and the left cover, The vehicle interior floor structure according to (1), wherein the protrusion is provided by the cover connecting portion. (3) The vehicle interior floor structure according to (1), wherein the protrusion is provided by making the floor carpet or floor panel located between the right cover and the left cover convex upward. (4) The vehicle interior floor structure according to (1), wherein a recess is provided on the underside of the front seat in the seating position to increase the vertical distance between it and the floor portion located between the right cover and the left cover. (5) The vehicle floor structure as described in (1), wherein the front seats are either tumble seats, jump-up seats, or space-up seats. [Effects of the Invention]

[0007] According to the vehicle interior floor structure described in (1) above, a convex portion extending in the left-right direction of the vehicle is provided on the floor area located between the right and left covers, so that the feet of rear-seat passengers cannot or cannot be placed further forward than the convex portion of the vehicle. As a result, when returning the front seats from the folded-up position to the seated position, interference between the front seats and the feet of rear-seat passengers can be suppressed.

[0008] According to the vehicle interior floor structure described in (2) above, since the protrusions are provided by the cover connecting parts, unlike cases where the protrusions are provided by the floor panels or floor carpets, the protrusions can be provided without changing the floor panels or floor carpets. In addition, since the right cover and the left cover are connected by the cover connecting parts, the right cover and the left cover can be made into a single component, thereby reducing the number of parts.

[0009] According to the vehicle interior floor structure described in (3) above, the protrusion is provided by making the floor carpet or floor panel located between the right cover and the left cover convex upwards. Therefore, the protrusion can be provided simply by making the floor carpet or floor panel convex, without increasing the number of parts.

[0010] According to the vehicle interior floor structure described in (4) above, a recess is provided on the underside of the front seats at the seating position, which widens the vertical distance between the floor area located between the right and left covers. This allows for increased legroom for rear passengers in the vertical direction. In this structure, the underside of the front seats is raised by providing a recess without lowering the floor surface. Unlike when the floor surface is lowered, this makes it easier to secure space for underfloor components located beneath the floor.

[0011] According to the vehicle cabin floor structure described in (5) above, regardless of whether the front row seat is a tumble seat, a jump-up seat, or a space-up seat, the same effects as those obtained in (1) above can be obtained.

[Figure 6] It is an enlarged plan view of the striker and the cover in a modified example of the embodiment of the present invention.

Modes for Carrying Out the Invention

[0013] 〔Example〕 Hereinafter, referring to the drawings, the vehicle cabin floor structure (simply referred to as the floor structure) 10 of the embodiment of the present invention will be described. In the drawings, UP indicates upward (above the vehicle), FR indicates the front of the vehicle, and RH indicates the right side in the vehicle's left-right direction.

[0014] The floor structure 10 of the embodiment of the present invention is applied to an automobile with three rows of seats provided in the vehicle's front-rear direction. As shown in FIG. 1, the floor structure 10 has a front row seat 20, a rear row seat 30, a striker 40, a cover 50, a first convex portion (corresponding to the convex portion in the claims) 60, a second convex portion 70, and a floor 80.

[0015] The front row seat 20 is the seat in the second row of the three-row seat. The rear row seat 30 is the seat in the third row of the three-row seat, and is a two-person seat arranged behind the front row seat 20 in the vehicle.

[0016] The front row seat 20 is capable of flipping up from the seating position 20a to the flipped-up position 20b. When the front row seat 2 is in the seating position 20a, a passenger (not shown in the figure) can sit on the front row seat 20. When the front row seat 20 is in the flipped-up position 20b, a passenger (not shown in the figure) cannot sit on the front row seat 20. The front row seat 20 is a tumble seat. After the seat back 22 is folded onto the seat cushion 21, the seat cushion 21 is flipped up forward in the vehicle together with the seat back 22, enabling it to flip up from the seating position 20a to the flipped-up position 20b.

[0017] However, although not shown in the figure, the front row seat 20 may be a space-up seat or a jump-up seat. A space-up seat is a seat with a mechanism that flips up laterally with respect to a tumble seat. After the seat back 22 is folded onto the seat cushion 21, the seat cushion 21 is flipped up laterally (horizontally) outside the vehicle in the left-right direction together with the seat back 22, enabling it to flip up from the seating position 20a to the flipped-up position 20b. A jump-up seat is a seat with a mechanism in which the seat back 22 is not folded. Only the seat cushion 21 can be flipped up without the seat back 22 being folded.

[0018] The front row seat 20 is a left-right split seat having a right seat 23 and a left seat 24 on the left side of the vehicle of the right seat 23. The front row seat 20 may be of a bench seat type with a substantially zero interval between the left and right seats 23 and 24, or of a split seat type with an interval between the left and right seats 23 and 24 larger than that of the bench seat type.

[0019] The striker 40 is made of metal and is fixed to the floor 80 of the passenger compartment. The striker 40 engages when the front row seat 20 is in the seated position 20a. The striker 40 has a rod-shaped portion 41 that is exposed from the cover 50 and extends in the left-right direction of the vehicle, and the front row seat 20 engages with this rod-shaped portion 41.

[0020] Strikers 40 are provided for the right seat 23 and for the left seat 24. For both the right seat 23 and the left seat 24, the striker 40 has a right striker 40a and a left striker 40b located to the left of the right striker 40a in the vehicle. All strikers 40 are in the same position in the front-rear direction of the vehicle.

[0021] The cover 50 is made of resin and is fixed to the floor 80. The cover 50 is positioned around the striker 40. Like the striker 40, there are separate covers 50 for the right seat 23 and the left seat 24. For both the right seat 23 and the left seat 24, the cover 50 has a right cover 50a and a left cover 50b located to the left of the right cover 50a in the vehicle. All covers 50 are in the same position in the front-rear direction of the vehicle. The right cover 50a is positioned around the right striker 40a, and the left cover 50b is positioned around the left striker 40b.

[0022] The right cover 50a and the left cover 50b each have a concave shape that is recessed downwards and opens upwards, and their opening edges have a front end 51 that is in front of the vehicle beyond the rod-shaped portion 41 of the striker 40 and extends in the left-right direction of the vehicle, a rear end 52 that is behind the vehicle beyond the rod-shaped portion 41 of the striker 40 and extends in the left-right direction of the vehicle, a right end 53 that extends in the front-rear direction of the vehicle and connects the right-side ends of the front end 51 and the rear end 52 of the vehicle, and a left end 54 that extends in the front-rear direction of the vehicle and connects the left-side ends of the front end 51 and the rear end 52 of the vehicle. The rod-shaped portion 41 of the striker 40 extends in the left-right direction of the vehicle so as to cross the midpoint between the front end 51 and the rear end 52.

[0023] As shown in Figure 5, the upward projection height (amount of projection into the passenger compartment) of the rear end 52 is higher than that of the front end 51, the right end 53, and the left end 54. When viewed from the left-right direction of the vehicle, the shape of the rear end 52 should preferably be triangular (including a roughly triangular shape) with the distance in the front-rear direction of the vehicle decreasing towards the top, in order to suppress damage and deformation when struck by the feet F of rear-seat passengers. In Figure 5, the projection heights of the front end 51, the right end 53, and the left end 54 are shown to be equal, but the front end 51 may be the lowest, and the projection heights of the right end 53 and the left end 54 may gradually increase from the front end 51 towards the rear end 52.

[0024] Returning to Figure 1, the first protrusion 60 is provided on the floor 80 located between the right cover 50a and the left cover 50b, extending in the left-right direction of the vehicle with an upward convex shape. The first protrusion 60 is provided between the front ends 51 of the right cover 50a and the left cover 50b. The front end 60a of the first protrusion 60 is at the same (or approximately the same) position in the longitudinal direction of the vehicle as the front end 51a of the front end 51. The rear end 60b of the first protrusion 60 is located further rear than the rear end 51b of the front end 51, and further forward than the center of the longitudinal direction of the vehicle of the left end 54 and the right end 53.

[0025] The height of the first protrusion 60 from the floor 80 should preferably be set relatively high in order to prevent rear-seat occupants' feet F from being placed beyond the first protrusion 60 and further forward in the vehicle. However, the higher it is, the greater the possibility that occupants will trip over the first protrusion 60, so it is preferable that it be set to, for example, about 10 mm.

[0026] The cover 50 extends in the left-right direction of the vehicle between the right cover 50a and the left cover 50b and further has a cover connecting portion 55 that connects the right cover 50a and the left cover 50b, and the first protrusion 60 is provided by this cover connecting portion 55.

[0027] As shown in Figure 3, the cover connecting portion 55 has a cross-sectional shape perpendicular to the vehicle's left-right direction, which is its extension direction, that is U-shaped or hat-shaped, opening downwards, and both ends 55a and 55b in the cross-sectional view are in contact with the floor 80. Note that the illustrated example shows the case where it is U-shaped.

[0028] As shown in Figure 2, the second protrusion 70 is provided on the floor 80 located between the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24, extending in the left-right direction of the vehicle with an upward convex shape. The second protrusion 70 is provided between the front ends 51 of the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24. The front end 70a of the second protrusion 70 is at the same (or approximately the same) vehicle longitudinal position as the front end 51a of the front end 51. The rear end 70b of the second protrusion 70 is located further rear than the rear end 51b of the front end 51, and further forward than the vehicle longitudinal center of the left end 54 and right end 53.

[0029] The height of the second protrusion 70 from the floor 80 should ideally be set relatively high to prevent rear-seat occupants' feet F from being placed beyond the second protrusion 70 and further forward in the vehicle. However, the higher it is, the greater the possibility of occupants tripping over the second protrusion 70, so it is desirable that it be set to, for example, about 10 mm.

[0030] The cover 50 extends in the left-right direction of the vehicle between the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24, and further has a second cover connecting portion 56 that connects to the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24, and the second protrusion 70 is provided by this second cover connecting portion 56.

[0031] The second cover connecting portion 56, although not shown in the figure, has a cross-sectional shape perpendicular to the vehicle's left-right direction of extension, which is a U-shape or hat shape that opens downwards, and both ends of its cross-sectional view are in contact with the floor 80.

[0032] As shown in Figures 3 and 4, the floor 80 has a metal floor panel 81 and a floor carpet 82 placed on its upper surface. A cross member 81a (Figure 3), which works in cooperation with the floor panel 81 to form a closed cross section structure in a cross-sectional view in the longitudinal direction of the vehicle, and a side member 81b (Figure 4), which works in cooperation with the floor panel 81 to form a closed cross section structure in a cross-sectional view in the lateral direction of the vehicle, are joined to the lower surface of the floor panel 81 in order to increase the rigidity of the floor panel 81.

[0033] The front seat 20 has a recess 26 on its underside 25 when it is in the seated position 20a, which widens the vertical distance between the seat and the floor 80 located between the right cover 50a and the left cover 50b. The recess 26 is provided to widen the vertical footrest space for the rear passenger's feet F. The recess 26 is provided only on the underside 25 when it is in the seated position 20a, on the part of the underside 25 that is further rear of the first protrusion 60. In addition, to achieve a similar effect, although not shown in the figures, it is desirable that a recess 26 be provided on the underside 25, which widens the vertical distance between the seat and the floor 80 located between the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24. This recess 26 is provided only on the underside 25 when it is in the seated position 20a, on the part of the underside 25 that is further rear of the second protrusion 70.

[0034] Next, the operation and effects of the embodiments of the present invention will be explained. (A) A first convex portion 60 is provided on the floor 80 located between the right cover 50a and the left cover 50b, extending in the left-right direction of the vehicle. As a result, the first convex portion 60 prevents or makes it difficult for the rear passenger's feet F to be placed further forward than the first convex portion 60. This prevents the front seat 20 from interfering with the rear passenger's feet F when returning the front seat 20 from the folded-up position 20b to the seated position 20a.

[0035] (B) Since the first protrusion 60 is provided by the cover connecting portion 55, unlike the case where the first protrusion 60 is provided by the floor panel 81 or floor carpet 82, the first protrusion 60 can be provided without modifying the floor panel 81 or floor carpet 82. Also, since the right cover 50a and the left cover 50b are connected by the cover connecting portion 55, the right cover 50a and the left cover 50b can be made into a single component, thereby reducing the number of parts.

[0036] (C) A recess 26 is provided on the underside 25 of the front seat 20 in the seating position 20a, which widens the vertical distance with the floor 80 located between the right cover 50a and the left cover 50b, thereby increasing the legroom for rear passengers in the vertical direction. In this structure, the underside 25 of the front seat 20 is raised by providing the recess 26 without lowering the floor surface, so unlike when the floor surface is lowered, it becomes easier to secure space for mounting underfloor components located below the floor 80.

[0037] (D) Regardless of whether the front row seat 20 is a tumble seat, a jump-up seat, or a space-up seat, the same effect as that obtained in (A) above can be obtained.

[0038] (E) The right cover 50a and the left cover 50b each have a front end 51, a rear end 52, a right end 53, and a left end 54, and the height of the rear end 52 is higher than the front end 51, the right end 53, and the left end 54, so that rear passengers cannot or cannot place their feet in front of the rear end 52. As a result, when returning the front seat 20 from the folded-up position 20b to the seated position 20a, interference between the front seat 20 and the rear passenger's feet F can be suppressed.

[0039] (F) Because the cover connecting portion 55 has a U-shape or hat shape with a cross-sectional shape perpendicular to the extension direction that opens downwards, the rigidity in the direction perpendicular to the extension direction can be increased compared to when it has a planar shape. Also, because it has a U-shape or hat shape that opens downwards, unlike when it has a U-shape or hat shape that opens upwards, forwards, or backwards, the ends 55a and 55b in the cross-sectional view can be prevented from protruding into the passenger compartment. As a result, the risk of occupants' shoes or other items getting caught on and damaged by the ends 55a and 55b in the cross-sectional view can be prevented.

[0040] (G) The cover connecting section 55 connects the front ends 51 of the right cover 50a and the left cover 50b, so that the legroom for rear passengers can be increased in the front-to-rear direction of the vehicle compared to when the rear ends 52 are connected to each other, or when the front ends 51 are not connected to each other.

[0041] (H) A second convex portion 70 is provided on the floor 80 located between the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24, extending in the left-right direction of the vehicle. As a result, the feet F of the rear seat occupants cannot or cannot be placed further forward than the second convex portion 70 between the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24. As a result, interference between the front seat 20 and the feet F of the rear seat occupants can be suppressed even between the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24.

[0042] (I) Since the second protrusion 70 is provided by the second cover connecting portion 56, unlike the case where the second protrusion 70 is provided by the floor panel 81 or floor carpet 82, the second protrusion 70 can be provided without modifying the floor panel 81 or floor carpet 82. Also, since the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24 are connected by the second cover connecting portion 56, the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24 can be made into a single component, thereby reducing the number of parts.

[0043] (J) Because the second cover connecting portion 56 has a U-shape or hat shape with a cross-sectional shape perpendicular to the extension direction that opens downwards, the rigidity in the direction perpendicular to the extension direction can be increased compared to the case of a planar shape. Also, because it has a U-shape or hat shape that opens downwards, unlike the case of a U-shape or hat shape that opens upwards, forwards, or backwards, the end in the cross-sectional view can be prevented from protruding into the passenger compartment. This prevents occupants' shoes, etc. from getting caught on the end in the cross-sectional view and getting damaged.

[0044] (K) The second cover connecting section 56 connects the front ends 51 of the left cover 50b for the right seat 23 and the right cover 50a for the left seat 24, so that the legroom for the rear seat occupants can be increased in the front-to-rear direction of the vehicle compared to when the rear ends 52 are connected and the front ends 51 are not connected.

[0045] [Example] (Figure 6) In the above embodiment of the present invention, the case in which the first protrusion 60 is provided by the cover connecting portion 55 of the cover 50 and the second protrusion 70 is provided by the second cover connecting portion 56 of the cover 50 was described. However, the first protrusion 60 and the second protrusion 70 may be configured as follows. In this modified example, the components corresponding to the above-described embodiment of the present invention are given a reference numeral that is the same as the reference numeral of the component plus 100. As shown in Figure 6, the first protrusion 160 and the second protrusion 170 may be provided by making the floor panel 181 or floor carpet 182 of the floor 180 convex upward. With this configuration, the first protrusion 160 and the second protrusion 170 can be provided simply by making the floor panel 181 or floor carpet 182 convex upward without increasing the number of parts.

[0046] Alternatively, it could be done as follows: (i) In the above embodiment of the present invention, the left and right covers 50a and 50b (four covers) for the left and right seats 23 and 24 are shown to be integrated, but it is also possible to have a configuration in which the covers are divided into two parts, one for the left and one for the left and one for the 24 seats (not shown). (ii) Although not shown in the figures, the first and second convex portions 60 and 70 may not be provided, but the color of the floor 80 at the locations where the first and second convex portions 60 and 70 would be provided may be made different from the surrounding area to alert rear-seat occupants. (iii) Although not shown in the illustration, the rear end 52 of the cover 50 may be made to stand out from the surrounding area, or a "no footrest" mark may be added to alert rear-seat passengers.
