Description

  The present invention relates to a vehicle cabin structure.

  For vehicles that can be used by a large number of passengers, such as one-box cars, a seat that has a generally rectangular shape when viewed in plan is traditionally used to improve passenger convenience and comfort. Various ingenuity has been applied, such as seat arrangement for seats with cushions. Patent Document 1 discloses a typical example of a vehicle cabin structure in which three rows of seats are arranged in the longitudinal direction of the vehicle body. That is, two rows of front and rear seats are arranged behind the independent driver seat and passenger seat on the left and right of the first seat row, and the second seat row is composed of two independent seats separated on the left and right. The third seat row is composed of bench seats that are continuous in the vehicle width direction, and the occupants of the second seat row and the third seat row open a pair of left and right rear side doors arranged on the sides of the second seat row. Getting on and off.

  Patent Document 1 also discloses a structure that allows the seats in the second seat row to slide in the front-rear direction and also in the vehicle width direction, and further includes a fourth that can be folded rearward of the third seat row. It proposes to add seat rows.

  In this type of one-box car, the driver's seat and the passenger's seat are separated from each other in order to move from the driver seat and the passenger seat in the first seat row to the seat row. When the second sheet row is composed of left and right independent sheets as in Document 1, the left and right sheets of the second sheet row are separated from each other so that the third sheet row can be accessed through the sheets. It is preferable that they can be arranged. As a result, a walk-through passage is formed that is movable from the first sheet row to the rearmost seat row located at the rear end of the vehicle body.

  In the one-box car, the passenger in the first seat row gets in and out of the passenger compartment by opening the left and right front side doors, and the passenger in the rear row of the first seat row, that is, the second to fourth seat rows, A pair of left and right rear side doors arranged on the rear side of the front side door, that is, on the side of the second seat row, or the rear side door provided on only one of the left and right sides is opened to get in and out of the passenger compartment. That is, the passenger in the seat row behind the first seat row is set to get on and off through the rear side door opening located on the side of the second seat row.

  From this, when the left and right seats constituting the second seat row positioned on the side of the rear side door are provided with a sliding mechanism in the vehicle width direction as disclosed in Patent Document 1, the third seat row is provided. When the passenger in the fourth row of seats gets on and off, it slides inward in the vehicle width direction to enlarge the floor area near the door opening of the rear side door, thereby improving the boarding / exiting ability. is there.

  Patent Document 2 relates to a second sheet row immediately after the first sheet row, adopts a relatively large sheet and a relatively small sheet division structure, and provides a front and rear slide mechanism for the relatively small sheet. Therefore, we have proposed a vehicle cabin structure that can realize various seat arrangements.

Japanese Patent Laid-Open No. 11-245695 JP 2000-62502 A

  As can be seen from the conventional example described above, techniques such as seat front / rear slide, vehicle width direction slide, seat folding, and seat back forward have been used to improve passenger occupancy, convenience, and comfort. However, in a small vehicle having a short front and rear length of the passenger compartment, the seat sliding mechanism and the folding mechanism become a problem that leads to an increase in the weight of the vehicle.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger compartment structure that can improve the comfort of passengers from a different viewpoint including the shape and movement of seats.

According to the present invention, the above technical problem is
A vehicle cabin structure comprising a rear seat row and a front seat row located in front of the rear seat row,
The front seat row is composed of left and right seats that are independent of each other and spaced from each other in the vehicle width direction.
The seat cushions of the left and right seats of the front seat row have arcuate outer contours that bulge rearward in a plan view, and thereby have a substantially trapezoidal shape that is widened toward the rear in front of the rear seat row. This is achieved by providing a passenger compartment structure characterized in that a floor area is formed.

  That is, in the present invention, paying attention to the shape of the seat cushion, the seat cushions of the left and right seats of the front seat row have arcuate outer contours that bulge rearward in plan view, whereby the rear seat row By forming a substantially trapezoidal floor area with a spread toward the rear in front of the vehicle, the foot space of the occupant seated in the rear seat row can be expanded without providing a front / rear slide mechanism or the like in the front seat row be able to. Therefore, it is possible to achieve both the technical demand for reducing the weight of the vehicle body and the demand for passenger comfort in order to reduce the size and fuel consumption of the vehicle.

In a preferred embodiment of the present invention, the rear seat row is composed of left and right seats that are independent from each other and spaced apart in the vehicle width direction.
An arcuate contour on the vehicle interior side at the rear edge of the left and right seats constituting the front seat row, and an arcuate contour on the vehicle interior side at the front edge of the left and right seats constituting the rear seat row, By forming a star-shaped foot floor area, the area for placing the hip on the seat cushion of the rear seat row is secured as before, and the front seat row does not have a front / rear slide mechanism or seat folding mechanism. However, it is possible to further increase the foot space of the occupant seated in the rear seat row, thereby providing a degree of freedom of the occupant's seating posture, for example, the occupant seated in the rear seat row assembles a foot. .

  In a preferred embodiment of the present invention, the front seat row and / or the rear seat row are arranged at a first position where the seat backs of the left and right seats constituting them face the front, and toward a vehicle longitudinal center line. It is possible to displace between the second position facing diagonally forward, so that the occupant seated on the seat with the seat back facing diagonally forward can extend its legs between the left and right seats positioned forward. it can.

  Further, by configuring the front seat row and the rear seat row with left and right seats, it is possible to walk through between the left and right seats of the front seat row and the left and right seats of the rear seat.

  In a preferred embodiment, the front seat row and / or the rear seat row rotate the left and right seat cushions constituting the front seat row and / or the rear seat row so that the seat backs of the left and right seats are integrated with the seat cushion. Can be displaced between the first position and the second position, so that when the occupant wants to extend his / her legs, the seat back can be moved to the second position to take a posture in which the legs are extended. Become.

  In the most typical embodiment, the seat cushions of the left and right seats included in the front seat row and the rear seat row are circular in a plan view, so that even if the seat cushion is rotated, There are advantages such as avoiding such interference, the advantage of being able to walk through easily from the front to the rear of the passenger compartment, and the ability to expand the foot space of the occupant. This has a great significance for light weight in a small vehicle with a short front and rear length of the passenger compartment, and can be an elemental technology that achieves both weight reduction and convenience and ease of getting on and off.

  The above-described rotatable seat back of the first row of seats may realize the rotation of the seat back by being integrated with the rotatable seat cushion, or if it is a separate seat back from the seat cushion The seat back itself may be designed to be rotatable. If the seat back is a seat integrated with the seat cushion, the vertical axis of the seat cushion may be set at the center of the seat cushion.

  The seat in which the seat back is displaceable is most preferably circular when the seat cushion is viewed in plan. According to this, even when the seat cushion is rotated, unlike the conventional rectangular seat cushion in plan view, there are no corners. There will be no problem of interference.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a side view showing an outline of a cabin structure of a one-box car, and FIG. 2 is a plan view thereof. The one-box car 1 has a passenger compartment 3 that extends to the rear end of the vehicle body behind the engine room 2, and the passenger compartment 3 includes second, third seat rows L2, L3 is disposed. Reference numeral 4 denotes a handle, 5 denotes left and right front wheels, and 6 denotes left and right rear wheels. In the drawings, “L” is added on the left side and “R” is added on the right side to identify left and right.

  The foremost first seat row L1 is composed of a driver seat 10 and a passenger seat 11, and these seats 10, 11 are composed of independent seats and are spaced apart in the vehicle width direction. . Similarly, the second sheet row L2 is also composed of two sheets 12 and 13 that are independent of each other, and the two sheets 12 and 13 are spaced apart from each other in the vehicle width direction. The third seat row L3 may be a bench seat type seat that is continuous in the vehicle width direction, but is preferably composed of two seats 14 and 15 that are independent of each other. It is better to arrange them apart in the direction.

  As can be seen from FIG. 2, the driver seat 10 and the passenger seat 11, the left and right intermediate seats 12 and 13, and the left and right rearmost seats 14 and 15 constituting each seat row L1 to L3 are all seat rows L1. ~ L3 are spaced apart from each other in the vehicle width direction and have a separation distance through which an occupant can pass between them. A walk-through passage WP extending in the front-rear direction is formed.

  The one-box car 1 includes a front side door 21 that opens and closes a pair of left and right front side door openings 20 at a position corresponding to the first seat row L1 in the front row, and a position corresponding to the center seat row, that is, the second seat row L2. A rear side door 23 that opens and closes each pair of left and right rear side door openings 22, and the occupant of the rearmost seat row, that is, the third seat row L3 shares the left and right rear side door openings 22 with the occupants of the second seat row L2. Thus, it is possible to get on and off through the rear side door opening 22.

  The front side door 21 typically employs a door type that opens at the front end and has a front end hinged to the rear side. The rear side door 23 is guided by a guide rail 24 extending in the longitudinal direction of the vehicle body and is moved rearward along the side wall of the vehicle body to open the rear side door opening 22, but is the same as the front side door 21. A door type with a front hinge and a rear opening may be adopted.

  As the sheets 10 to 15 constituting the three front and rear sheet rows L1 to L3, basically, it is preferable to adopt the sheets having the same configuration. Each of the seats 10 to 15 includes a seat cushion 16 and a seat back 17.

  Each sheet 10-15 is installed in floor F via pedestal 30 provided with height. As can be seen from FIG. 2, the pedestal 30 has, for example, a hexagonal column shape. The pedestal 30 extends along a longitudinal direction of the vehicle body along a pair of opposite sides and has a pair of opposite sides facing each other. It arrange | positions so that it may extend along the width direction. The seat cushion 16 is installed on the pedestal 30, but the pedestal 30 is smaller than the seat cushion 16 in a plan view and is positioned at the center of the seat cushion 16.

  At least the driver's seat 10 is preferably movable in the longitudinal direction of the vehicle body by a sliding mechanism extending in the longitudinal direction, but the other seats 11 to 15 may be fixed without the longitudinal sliding mechanism. Further, the seats 10 to 15 constituting the front row seat row L1 and the third seat row L3 may be arranged with their seat backs 17 facing directly in the same manner as the driver seat 10, but for example the second seat row L2 The right and left seats 12 and 13 are preferably arranged so that their seat backs 17 are slightly inclined forward from the front to the vehicle longitudinal direction center line (FIG. 2).

  Referring to FIG. 3, FIG. 3 shows an example in which the seat backs 17 of all the seats 10 to 15 are arranged directly in front, and the occupant seated in the second seat row L2 The rear end edges of the seat cushion 16 of the driver seat 10 and the passenger seat 11 in the foremost seat row L1 positioned at the front are not rectangular in a plan view as in the prior art, but at least the corners on the vehicle interior side. Since the cut-out shape is typically an arc shape, a margin can be provided around the knee and the foot with respect to the margin relating to the foot 32 of the occupant seated in the second seat row L2. The same applies to the occupant seated in the third seat row L3, with the rear end edge of the arc shape in which the vehicle interior side of the seat cushion 16 of each seat 12, 13 of the second seat row L2 bulges rearward. The occupant seated in the third seat row L3 can be given a margin around the knee and the feet.

  Further, the pedestal 30 of each sheet 10-15, in particular, the pedestal 30 of the sheets 10-13 of the foremost sheet row L1 and the second sheet row L2, has a shape with a corner portion called a hexagonal column cut out and having a height. Therefore, the space for placing the feet of the passengers seated in the second seat row L2 and the third seat row L3 can be expanded. That is, for example, an occupant seated in the second seat row L2 can place his / her feet under the seat cushion 16 in the foremost seat row L1, so that there is a further margin at the foot of the occupant in the second seat row L2. Can be provided. If it is a passenger | crew of the 3rd seat row | line | column L3, since a leg | foot can be put under the seat cushion 16 of the 2nd seat row | line | column L2, it is possible to provide a further margin for the feet of the occupant of this third seat row L3. it can.

  It goes without saying that the shape of the hexagonal column of the pedestal 30 is merely an example. For at least the pedestal 30 of the foremost sheet row L1 and / or the second sheet row L2, for example, if it is the pedestal 30 of the second sheet row L2, the third sheet row L3 located behind the rear end surface, that is, the second sheet row L2. By adopting a hexagonal column, a cylinder, or the like in which the left and right sides are cut out, the foot space of the occupant seated in the third seat row L3 can be expanded. This means that in a relatively small vehicle having a short front and rear length of the passenger compartment, it is possible to widen the suspension of the occupants located in the second and third seat rows L2 and L3, thereby the second and third seat rows. The front and rear slide mechanism can be omitted from the L2 and L3 sheets 12-15.

  As described above, the pedestal 30 is preferably smaller than the seat cushion 16 in plan view. However, the diameter of the pedestal 30 is a design matter, and for example, it is considerably larger than the seat cushion 16 like a support column. It may be small.

  As illustrated in FIG. 2, when the left and right seat backs 17, 17 of the second sheet row L <b> 2 are inclined in a direction away from each other, as shown by reference numeral 34, the third sheet row A trapezoidal foot space can be provided for the L3 occupant.

  In this way, in order to create a state in which the left and right seat backs 17, 17 of the second seat row L2 are displaced in a direction away from each other, for example, the seats 12, 13 constituting the second seat row L2 are replaced with the driver seat 10 Similarly, between the first position in which the seat back 17 faces directly in front and the second position in which the left and right seat backs 17 and 17 are obliquely forward toward the center line in the longitudinal direction of the vehicle body. It may be designed to be rotatable. Regarding the rotation of the seats 12 and 13 in the second seat row L2, the seat back 17 may be able to take the first position and the second position by rotating the seat cushion 16, but a circular seat The seat back 17 may be rotated along the rounded outer contour of the seat cushion 16 with the cushion 16 in a stationary state so that the first position and the second position can be taken.

  FIG. 4 shows an example in which the seat back 17 is set so as to be rotatable along an arc-shaped contour bulging rearward of the seat cushion 16 while the seat cushion 16 of the second seat row L2 is fixed. It is. In FIG. 4, an arrow is attached to the seat cushion 16 of the driver seat 10 in the front-rear direction. This indicates that the driver seat 10 can slide in the front-rear direction together with the seat back 17. It is shown.

  As described above, by designing the seat back 17 of the second seat row L2 to be rotatable to the retracted position displaced toward the vehicle interior independently of the seat cushion 16, as shown in FIG. Even when the occupant is seated in the second seat row L2 when opening the seat 23 and trying to get into the third seat row L3, the seat back 17 is rotated to the vehicle interior side to rotate the third seat row L3. It is easy to get into the seat row L3. This is the same when the passenger seated in the third seat row L3 gets out of the vehicle. That is, by designing the seat back 17 of the second seat row L2 so as to be rotatable to the retracted position along the outer contour that bulges behind the rear end edge of the seat cushion 16, the seats 12 of the second seat row L2, The passenger can get in and out of the third seat row L3 by rotating the seat back 17 toward the vehicle interior side while the occupant is seated in the second seat row L2, without sliding the seat 13 forward or moving the seat back 17 forward. Can be improved.

  From the viewpoint of improving the ease of getting on and off the seat rows L2 and L3 behind the first seat row L1, the seat back 17 of the seats 12 and 13 in the second seat row L2 adjacent to the rear side door 23 is placed in the vehicle interior. When the rear side door 23 is installed only on one side of the vehicle body and the other side is a vehicle without a door, the seat back of the seat 12 or 13 on the side of the rear side door 23 is used. Of course, only 17 may be designed to be rotatable.

  FIG. 5 shows a modification example in which the left and right seat backs 17, 17 are displaced in a direction away from each other and set to a second position obliquely forward toward the center line in the longitudinal direction of the vehicle body with respect to the third seat row L3. FIG. 6 is a diagram corresponding to this. As can be seen best from FIG. 6, the seat backs 17 of all the seats 12 to 15 constituting the rear seat, that is, the second and third seat rows L2 and L3, which are located behind the front row seat row L1, are the first. By installing at two positions, for the occupant seated in the third seat row L3, an arcuate contour on the vehicle interior side at the rear edge of the left and right seat cushions 16, 16 of the second seat row L2, A star-shaped foot space 36 can be provided by the arcuate contours on the vehicle interior side at the front end edges of the left and right seat cushions 16, 16 of the third seat row L3. As a result, the occupant seated in the third seat row L3 can take an arbitrary sitting posture (FIG. 7). Further, even for the passenger in the second seat row L2, the trapezoidal foot space between the driver's seat 10 and the passenger seat 11 in the front row seat row L1 (see the trapezoidal space indicated by reference numeral 34 in FIG. 4) It is possible to provide a foot space with a margin for the passenger in the second seat row L2 (FIG. 7). Of course, even in this case, the seat back 17 of the sheets 12 and 13 in the second sheet row L2 can be rotated to the retreat position as described with reference to FIG. It is preferable to provide convenience for passengers to get on and off.

  Further, the second and third sheet rows L2, L3 are provided by installing the seat backs 17 of the seats 12-15 of the second and third seat rows L2, L3 behind the front row seat row L1 in the second position. Since the front view of the occupant seated slightly diagonally forward is performed through the space between the driver's seat 10 of the front row seat row L1 and the seat backs 17, 17 of the passenger seat 11, the second, second It is possible to reduce the front view of the occupants in the three seat rows L2 and L3 from being narrowed by the front seat back 17, and thus it is possible to widen the front view of the occupants in the seat rows L2 and L3.

  Thus, regarding the installation of the seats 12 to 15 in the second and third seat rows L2 and L3 located behind the foremost seat row L1, the seat backs 17 of these seats 12 to 15 are disposed. It may be designed to be rotatable so that the first position and the second position can be taken by the operation of the occupant. In this case, the seat backs 17 of the seats 12 to 15 may be designed to rotate independently from the seat cushion 16, but as a modification, the seat cushion 16 is designed to be rotatable, and the seat cushion 16 Alternatively, the seat back 17 may be designed to rotate integrally. Here, since the seat cushion 16 is circular in plan view, that is, not rectangular in plan view, but has a shape in which the four corners are notched, even if the seat cushion 16 is rotated on a horizontal plane, the seat cushion 16 There is no problem that the front edge of the door interferes with, for example, the vehicle interior wall.

  As described above, the seat cushion 16 may be designed to rotate on a horizontal plane and the seat back 17 may be rotated along with the rotation of the seats 12 and 13 of the second seat row L2. However, the vertical axis 38 of the seat cushion 16 of the second seat row L2 is offset forward from the center O of the circular seat cushion 16, so that the seat back 17 is greatly displaced by a slight rotation of the seat cushion 16. Also good.

  One example of the offset arrangement of the vertical shaft 38 is shown in FIGS. 8 and 9, and another example is shown in FIGS. 10 and 11. In the example of FIGS. 8 and 9, when the seats 12 and 13 of the second seat row L2 are in the first position, that is, in a state where the seat back 17 is directed directly in front, the imaginary extending right side through the center O of the seat cushion 16. Of the four regions defined by the horizontal line and the virtual vertical line extending in the front-rear direction orthogonal to the virtual horizontal line, the vertical axis 38 of the seat cushion 16 is located outside the virtual vertical line and in front of the virtual horizontal line. Is installed. By setting such an offset position of the vertical shaft 38, as shown in FIG. 9, when an occupant riding in the one-box car 1 gets into the third seat row L3 through the rear side door opening 22, the second seat row L2 When the seat 12 or 13 is rotated, as can be seen from FIGS. 8 and 9, the seat 12 or 13 of the second seat row L2 is displaced toward the vehicle interior and the seat cushion 16 is moved to the vehicle. It is possible to increase the width dimension of the entrance region to the third sheet row L3 by being displaced indoors and forward. Therefore, the boarding / exiting property to the third sheet row L3 can be improved.

  Regarding the improvement of passenger occupancy of the third seat row L3 by offsetting the vertical shaft 38, the seat cushion 16 of the seats 12, 13 of the second seat row L2 adjacent to the rear side door 23 is centered on the vertical shaft 38. When designing to be rotatable, for example, when the rear side door 23 is installed only on one side of the vehicle body and the other side is a vehicle without a door, only the seat cushion 16 of the seat 12 or 13 on the rear side door 23 side is provided. Of course, it may be designed to be rotatable.

  In the example of FIGS. 10 and 11, with respect to the setting of the vertical axis 38 of the seats 12 and 13 of the second seat row L2, a virtual horizontal line extending right side through the center O of the seat cushion 16 and orthogonal to the virtual horizontal line The vertical axis 38 of the seat cushion 16 is installed inside the virtual vertical line and in front of the virtual horizontal line among the four regions partitioned by the virtual vertical line extending in the front-rear direction. By setting such an offset position of the vertical shaft 38, as shown in FIG. 11, the second position, that is, the seat back 17 is centered in the longitudinal direction of the vehicle body from the first position where the occupant of the second seat row L2 faces the front. When the seats 12 and / or 13 are rotated to a position facing diagonally forward toward the line, the seats 12 or 13 of the second seat row L2 are displaced outward and forward of the passenger compartment, and left and right of the second seat row L2 The distance between the seats 12 and 13 is increased, and the distance between the second seat row L2 and the third seat row L3 is increased, thereby increasing the foot space of the passenger in the third seat row L3. Yes (FIG. 11). 8 to 10, the sheets 14 and 15 of the third sheet row L3 are illustrated at the first position facing directly in front, but may be at the second position facing obliquely. As described above, it may be rotatable between the position and the second position.
