  In the driving posture adjusting device for a vehicle disclosed in Patent Document 1 above, for example, the seat position adjusting means moves the driver's seat back and forth according to the height of the driver sitting on the driver's seat, and in response to this, Because the seat cushion can be adjusted in the vertical position and the tilt angle, the accelerator pedal or the brake pedal is arranged in front of the driver seat while maintaining the seating posture of the driver seated on the driver seat. It is possible to properly perform the depressing operation of the operation pedal composed of the above, and to adjust the driver's seating posture so that the front view can be appropriately secured. In addition, if the driver sitting on the driver's seat changes to a person with a different height and the length of the foot, the size of the sole, etc. changes, the floor panel position adjusting means will respond to this by moving the top and bottom of the movable floor. Since the position can be adjusted, the lever ball portion of the pedal operation foot can be properly brought into contact with the pedal surface portion of the operation pedal in a state where the heel portion of each driver is placed on the floor panel. There is an advantage that the depression characteristic of the operation pedal can be adjusted as possible.

  However, as described above, the front and rear position of the driver's seat and the vertical position and inclination angle of the seat cushion can be adjusted by the seat position adjusting means, and the vertical position of the movable floor panel is adjusted by the floor panel position adjusting means. If it is possible, there is a problem that the structure of the adjusting device is complicated and the manufacturing cost is increased. In particular, since the floor panel position adjusting means must be installed in a narrow gap formed between the movable floor and the floor panel located below the movable floor, it is possible to sufficiently secure the installation space. There were problems such as difficulty. Even when the vertical position of the movable floor panel is adjusted to an appropriate value by the floor panel position adjusting means, the driver's pedal is affected by the adjustment of the position and angle of the driver's seat by the seat position adjusting means. Since operability and the like change, it is extremely difficult to adjust all of the position and angle of the driver seat and the vertical position of the movable floor panel to appropriate values.

  On the other hand, in the floor structure of the driver's seat disclosed in Patent Document 2, a short stature seated on the driver's seat places the buttocks of the pedal operation feet on the first heel mounting portion. While maintaining the ankle angle and the inclination angle of the sole of the foot at an appropriate angle, the lever ball portion of the pedal operation foot can be brought into contact with the stepping point of the accelerator pedal. There is an advantage that it is possible to effectively prevent the delicate pedal operation from becoming impossible due to the accelerator pedal depressing operation being performed in a state separated from the vehicle. In the case of a tall person, the heel portion of the pedal operation foot is positioned behind the rear end portion of the first heel placement portion and on the side side portion of the second heel placement portion. In this state, it is possible to perform a pedal switching operation or the like for the accelerator pedal and the brake pedal. Therefore, it is possible to effectively prevent occurrence of a situation where the pedal switching operation is inhibited by the first and second heel mounting portions. There are advantages such as prevention.

  Further, as the drive shaft 70 is rotationally driven, the center link 67 is swung and displaced, and the driving force is transmitted to the rear link 65 via the connecting link 69, so that the rear link 65 is swung. In addition to the dynamic displacement, the tilt angle of the seat cushion 1a is adjusted by the swinging displacement of the front link 63 corresponding thereto. That is, at the retracted position where the seat cushion 1a of the driver's seat 1 moves to the rear side of the vehicle body, as shown in FIG. 6, the front link 63 and the central link 67 are inclined backward, and the rear link 65 Since the connecting shaft 66 provided at the rear end of the seat cushion is positioned below, the seat surface of the seat cushion 1a is held in a state of being largely inclined backward.

  In the above configuration, when an operation for moving the driver's seat 1 to the front side of the vehicle by the front / rear adjustment switch is performed, the drive motor 75 of the tilt angle adjustment mechanism 3 is adjusted based on the preset drive characteristics. A control signal for driving the rotation is output from a control means (not shown), and the normal driving force of the driving motor 75 is transmitted through the gear mechanism 76, the screw shaft 74, the connecting pin 73, the driving lever 71 and the driving shaft 70 to the central link. 67, the central link 67 shifts from the rearward tilt state to the standing state shown in FIG. Then, as the central link 67 shifts to the standing state, the driving force is transmitted to the rear link 65 via the connecting link 69, and the front end portion of the rear link 65 is pulled to the front side of the vehicle. The connecting shaft 66 provided at the rear end portion of the rear link 65 is raised, and the rear end portion of the seat cushion 1a is driven to be pushed up accordingly.

  In addition, since the front link 63 shifts from the rearward tilted state to the standing state in conjunction with the swinging displacement of the rear link 65, the front end portion of the seat cushion 1a is moved upward while being pushed up accordingly. When driven, the seat cushion 1a is displaced from the lower position to the upper position shown in FIG. Furthermore, the rearward movement angle of the seat cushion 1a is set to be larger than the upper movement amount of the front end portion of the seat cushion 1a, so that the rearward inclination angle of the seating surface is increased according to the upward movement of the seat cushion 1a. It changes so that it may become small gradually, and it is comprised so that it may approach a horizontal state. In conjunction with this, the inclination angle of the seat back 1b changes and is displaced so as to approach the vertical state.

  On the other hand, when an operation for moving the driver's seat 1 to the rear side of the vehicle body is performed by the front / rear adjustment switch, the drive motor 75 of the tilt angle adjustment mechanism 3 is driven in reverse based on a preset drive characteristic. A control signal is output from the control means, and the forward drive force of the drive motor 75 is transmitted to the central link 67 through the gear mechanism 76, the screw shaft 74, the connecting pin 73, the drive lever 71 and the drive shaft 70. As a result, the seat cushion 1a is displaced from the upper position to the lower position shown in FIG. 8, and the rearward inclination angle of the seat surface gradually increases as the seat cushion 1a moves downward. The back 1b is configured to be largely inclined backward.

  When the driver sitting on the driver's seat 1 changes to a person with a different height, the driver's seat height, arm length, foot length, etc. change in proportion to the height. Thus, the operability of the driver sitting on the driver's seat 1 with respect to the eye point and the operation pedal also changes. Therefore, the driver who newly sits on the driver's seat 1 holds the steering handle 48 in an appropriate state while maintaining the comfortable posture and, for example, the accelerator pedal 4 including the convex portion 23 of the pedal body 18 and the like. The front / rear position adjustment mechanism 2 and the tilting mechanism are arranged so that the lever ball portion of the pedal operation foot is brought into contact with the proper position of the pedal in an appropriate state and the eye point is aligned with the appropriate line L so that the front view can be properly secured. An attempt is made to adjust the front-rear position and the like of the driver seat 1 by operating the angle adjustment mechanism 3.

  There is a possibility that drivers having various heights and shapes from the person with a height of 150 cm or less to a person with a height of 190 cm or more may be seated on the driver seat 1. It is necessary to configure so that the user can sit down and perform a proper driving operation. For example, as a result of statistically analyzing the comfort posture of the average height M, which is considered to be 174 cm, and the average height M of the average height M that is most likely to sit on the driver's seat 1 is obtained, the following data is obtained. It was.

  The comfortable posture of the occupant seated on the driver's seat 1 means a seating posture that can stably maintain the seated state for a long period of time and is suitable for handle operation, pedal operation, and the like. Specifically, as shown in FIG. 14, the ankle angle θ1 of the pedal operation foot is about 85 ° to 95 °, the knee angle θ2 is about 115 ° to 135 °, and the upper body and the thigh from the hip to the shoulder. And the bending angle θ3 is about 95 °. In the case of the average height person M, the appropriate angle of the rhino angle θ4, which is the angle formed by the thighs with respect to the horizontal line, is a value obtained by adding approximately 1.5 ° to the inclination angle of the seat cushion 1a. This has been confirmed by ergonomic experiments. Further, the elbow angle θ5 at which the steering handle 48 can be properly operated is about 100 ° to 130 °, and the side angle θ6 is about 20 ° to 45 °.

  Therefore, the average height person M sets, for example, the ankle angle θ1 to 90 °, the knee angle θ2 to 125 °, the bending angle θ3 between the upper body and the thigh from the hip to the shoulder to 95 °, and When sitting on the driver's seat 1 with the rhino angle θ4 set to 17 °, the eye point Im of the average height person M may be made to coincide with the appropriate line L inclined forward and downward at an angle of about 8 °, for example. The front and rear reference position, the vertical reference height, and the reference inclination angle of the seat cushion 1a are set so as to be able to do so.

  In the standard sitting state of the average height person M as described above, the elbow angle θ5 and the side angle θ6 are set within the above range, and the steering handle 48 can be properly gripped. Further, as shown in FIG. 15, the heel portion Km of the pedal operation foot is placed at a predetermined position on the inclined floor portion 15, and the inclination angle θ7 of the sole surface with respect to the horizontal line is set to about 59.5 °, for example. In this state, the lever position Bm can be brought into contact with an appropriate position of the accelerator pedal 4, for example, an upper portion of the convex surface portion 23 close to the flat surface portion 24 provided on the pedal body 18. Further, the accelerator pedal 4 is provided.

  In FIG. 14, Hm is the hip point (sitting reference point) of the average height person M seated on the driver's seat 1. Further, in this embodiment, as shown by the solid line in FIG. 15, the intermediate height 15 c provided on the inclined floor portion 15, for example, the reference position where the average height person M places the heel portion Km of the pedal operation foot, Or it is set on the front part of the driver seat side part 15b provided in the back side.

  When the driver seated on the driver seat 1 changes from the average stature M to the short stature S composed of a female driver or the like, as shown by the phantom line in FIG. 14, the short stature S The front / rear position adjusting mechanism 2 and the inclination angle adjusting mechanism 3 are operated to ensure that the eye point Is can be matched with the appropriate line L while ensuring the handle operability and the pedal operability. The seat cushion 1a is moved forward, and in response to this, the installation height of the seat cushion 1a is raised, and the inclination angle of the seat cushion 1a with respect to the horizontal line is decreased.

  For example, when a short stature person S having a height of 150 cm sits on the driver's seat 1, the hip point Hs located on the seat cushion 1a is set to, for example, 105 mm from the front and rear reference position Hm for the average height person M. The hip point Hs is moved about 25 mm upward in conjunction with the movement, and the inclination angle of the seat cushion 1a is changed so that the rhino angle θ4 is about 10.5 °. Manipulate. As a result, the upper body of the short stature S with short arms compared to the average height M can be moved forward to grip the steering handle 48 in an appropriate state, and the sitting height compared to the average height M can be increased. By moving the eye point Is of the low short stature S to the upper front side of the vehicle body, it can be matched with the appropriate line L.

  Further, since the pedal operating foot of the short stature S tends to move upward in the front part of the vehicle body in accordance with the forward movement and upward movement of the seat cushion 1a, the knee angle θ2 is set to about 130 ° correspondingly. In this way, the ankle angle θ1 is maintained at about 90 °, and the lever ball portion Bs of the pedal operating foot made up of the right foot of the short stature S is provided on the pedal body 18 of the accelerator pedal 4. It is possible to make it abut on an appropriate position including the upper part of the convex surface portion 23 close to the surface portion 24.

  Since the distance (about 160 mm) from the buttocks Ks of the short stature S to the palm ball Bs is about 30 mm shorter than the same distance (about 190 mm) of the average stature M, the short stature S An attempt is made to bring the lever ball part Bs of the pedal operation foot into contact with the appropriate position of the accelerator pedal 4 while maintaining the sole inclination angle θ7 at the same angle as the average height (59.5 °). The buttocks Ks is positioned approximately 26 mm (= sin 59.5 ° × 30 mm) above the buttocks Km of the average tall person M. For this reason, if the short stature S does not allow the pedal-operated foot's heel Ks to float above the floor panel 9, the pedal-operated foot's lion sphere Bs is set to an appropriate value of the convex-shaped portion 23. When the heel portion Ks of the pedal operating foot cannot be accurately brought into contact with the upper portion or the like, and the heel portion Ks of the pedal operation foot is floated above the floor panel 9, a delicate pedal with the heel portion Ks as a fulcrum is used. It becomes difficult to perform the operation properly.

  However, when the inclination angle α2 of the operation pedal side portion 15b provided on the front side of the intermediate area 15c of the inclined floor portion 15 is set to 20 °, for example, as shown by a virtual line in FIG. The short stature person S changes the inclination angle θ7 of the sole of the foot from, for example, about 59.5 ° to 67 °, and the heel portion Ks of the pedal operation foot is set to the reference position on the inclined floor portion 15 (the average height M's heel By moving about 27 mm forward from the mounting position of the portion Km), the collar Ks is placed on the operation pedal side portion 15b of the inclined floor portion 15 located about 10 mm above the rear horizontal plane portion. The accelerator ball operation can be performed by bringing the lever ball portion Bs into contact with an appropriate position including an upper portion of the convex surface portion 23 provided on the accelerator pedal 4 in the mounted state.

  Note that the ankle angle θ1 of the pedal operation foot tends to be smaller than 90 ° in response to the inclination angle θ7 of the foot sole changing from 59.5 ° to 67 °. In response to the increase of θ7, the short stature S increases its knee angle θ2 to be greater than 130 ° and stretches the knee to make it look like it (see the phantom line in FIG. 14), so that the ankle angle θ1 exceeds the appropriate range. Can be prevented, for example, 85 ° or less.

  On the other hand, as shown in FIG. 16, when a tall person T having a height of, for example, 189 cm sits on the driver's seat 1, the hip point Ht located on the seat cushion 1a is used for the average height person M. The seat cushion is moved backward from the front and rear reference position Hm, for example, by about 85 mm, and in conjunction with this, the hip point Hs is moved downward by about 20 mm, and the rhino angle θ4 is set to about 20.0 °. It operates so that the inclination angle of 1a may be changed. As a result, the upper body of the tall person T having a long arm compared to the average tall person M can be moved rearward to hold the steering handle 48 in an appropriate state, and the sitting height is higher than that of the average tall person M. By moving the eye point It of the tall person T to the lower rear side of the vehicle body, it can be matched with the appropriate line L.

  Further, since the pedal operation foot of the tall person T tends to move downward in the rear part of the vehicle body in accordance with the backward movement and downward movement of the seat cushion 1a, the knee angle θ2 is set to about 120 ° correspondingly. By reducing the height, the tall person T maintains the ankle angle θ1 at about 90 °, while the lever ball portion Bt of the pedal operation foot is made up of the accelerator pedal 4 including the upper portion of the convex surface portion 23 and the like. It can be brought into contact with an appropriate position.

  Since the distance (about 206 mm) from the buttocks Kt of the tall person T to the egg ball part Bt is about 16 mm longer than the same distance (about 190 mm) of the average tall person M, the height of the tall person T When the sole inclination angle θ7 is maintained at the same angle (59.5 °) and the mounting position of the buttocks Kt is set to the same position, the insulator ball with respect to the convex surface portion 23 of the accelerator pedal 4 and the like It is necessary to displace the contact position of the part Bt by about 14 mm (= sin 59.5 ° × 16 mm) below the average height person M.

  In the first embodiment, the sole inclination angle θ7 of the tall person T is changed from, for example, about 59.5 ° to 57 °, and, as shown in FIG. If it is made to move on the horizontal plane part which consists of the installation part of the floor carpet 12 provided in the driver seat side part 15a provided in the back part of the rear part, the palm ball part Bt of the tall person T It is possible to perform a proper depressing operation in a state in which is in contact with the appropriate position of the accelerator pedal 4. Note that the ankle angle θ1 of the pedal operation foot tends to be larger than 90 ° in response to the inclination angle θ7 of the foot sole changing from about 59.5 ° to 57 °. Corresponding to the decrease in the angle θ7, by making the knee angle θ2 smaller than 120 ° and bending the knee (see FIG. 16), the ankle angle θ1 increases beyond the appropriate range, for example, 95 °. This can be prevented.

  As described above, the driver's seat 1 is disposed above the floor panel 9 that forms the bottom of the passenger compartment, and an operation pedal including an accelerator pedal 4 and a brake pedal 5 is disposed in front of the driver's seat 1. In the installed vehicle, an inclined floor portion 15 inclined upward is provided in the heel portion mounting region on the floor panel 9 on which the heel portion of the pedal operation foot is placed when the operation pedal is depressed. In addition, since a horizontal plane portion 16 serving as a mounted portion to which the front portion of the floor mat 14 is attached is provided between the front end portion of the inclined floor portion 15 and the operation pedal installation portion including the accelerator pedal 4 and the like, With such a configuration, the pedal operability can be effectively improved, and the floor mat 14 can be stably installed.

  In other words, the horizontal surface portion 16 is omitted, and the floor mat 14 is fixed to the surface material 11 of the floor carpet 12 in a state where the front portion of the floor mat 14 is placed on the inclined surface portion inclined upward. Such a configuration is also conceivable. However, when configured in this manner, the front portion of the floor mat 14 easily slides or separates from the inclined surface portion, so that it is difficult to stably install the floor mat 14. On the other hand, as shown in the first embodiment, an attached portion including a horizontal surface portion 16 to which the front portion of the floor mat 14 is attached is provided, and the front portion of the floor mat 14 is placed on the horizontal surface portion 16. When configured to do so, there is an advantage that the floor mat 14 can be stably fixed on the floor panel 9.

  And since the inclined floor part 15 which the upper surface inclined forward is formed in the collar part mounting area | region located in the back side of the operation pedal which consists of the said accelerator pedal 4, as shown to the virtual line of FIG. 15 and FIG. Even if the sole height is short compared with the average height person M, by placing the heel part Ks of the pedal operation foot on the front part of the first inclined floor part 15, While the ankle angle θ1 and the inclination angle θ7 of the foot sole are maintained at appropriate angles with the heel portion Ks positioned relatively upward, the insulator ball portion Bs is provided on a flat surface provided on the accelerator pedal 4, for example. It can be brought into contact with an appropriate position composed of the upper portion of the convex surface portion 23 and the like close to the surface portion 24.

  Therefore, the above-mentioned short stature S becomes in a state where the heel portion Ks of the pedal operation foot is separated from the floor surface, so that the subtle pedal operation becomes impossible, or the ankle angle θ1 and the inclination angle of the sole of the foot In a state where the buttocks Ks of the short stature S is placed on the inclined floor portion 15 without making it difficult to quickly depress the operation pedal due to the great deviation of θ7 from the appropriate angle, There is an advantage that the delicate pedal operations of the accelerator pedal 4 and the like can be appropriately performed by bringing the above-described insulator ball portion Bs into contact with an appropriate position.

  Further, in the case of a tall person T, for example, as shown in FIG. 16, if the sole inclination angle θ7 of the pedal operation foot is decreased and the knee angle θ2 is decreased, the buttocks Kt is moved downward as much. Without this, the lever ball portion Bt of the pedal operation foot can be easily and properly brought into contact with an appropriate position of the accelerator pedal 4 or the like. Therefore, as shown in FIG. 17 and the like, the tall person T places the heel part Kt of the pedal operation foot on the rear part of the inclined floor part 15 or on the horizontal surface part provided on the rear side thereof. In a state where the above-mentioned insulator ball part Bt is brought into contact with an appropriate position of the operation pedal, it is possible to appropriately perform a delicate depression operation of the operation pedal.

  In the first embodiment, as shown in FIG. 3 and the like, the floor panel on which the buttocks of the pedal operation foot made up of the right foot of the driver is placed when the operation pedal made up of the accelerator pedal 4 or the like is depressed. 9 is provided with an inclined floor portion 15 whose upper surface is inclined forwardly upward, and an inclination angle α2 of the inclined floor portion 15 at the operation pedal portion 15b is defined as an inclination angle of the driver seat portion 15a. Since the angle is set steeper than α1, even if the sole dimensions change according to the physique of the driver seated on the driver's seat 1, the pedal operation can be performed more appropriately with a simple configuration. There is an advantage.

  That is, in the first embodiment, the inclination angle α1 at the driver seat portion 15a of the inclined floor portion 15 is set within the range of 15 ° to 5 °, and the inclination angle α2 of the operation pedal portion 15b is set to 25 ° to 25 °. Since the angle is set within the range of 15 °, even if the height of the short S is shorter than that of the average height M, the heel Ks of the pedal operation foot is closer to the operation pedal of the inclined floor 15. By placing on the part 15b, the ankle angle θ1 and the inclination angle θ7 of the sole are maintained at appropriate angles while the hip Ks is positioned relatively upward. For example, it can be brought into contact with an appropriate position composed of an upper portion of the convex surface portion 23 adjacent to the flat surface portion 24 provided on the accelerator pedal 4. Therefore, when the short stature person S places the heel part Ks of the pedal operation foot on the operation pedal side portion 15b of the inclined floor part 15, the above-mentioned palm ball part Bs is brought into contact with an appropriate position. There is an advantage that the accelerator pedal 4 and the like can be easily and accurately depressed.

  On the other hand, as shown in FIGS. 16 and 17, in the case of a tall person T, if the sole inclination angle θ7 of the pedal operation foot is decreased and the knee angle θ2 is decreased, the heel part Kt is lowered downward. Without moving, the lever ball part Bt of the pedal operation foot can be easily and properly brought into contact with an appropriate position of the accelerator pedal 4 or the like. Therefore, as described above, the inclination angle α1 in the driver seat portion 15a of the inclined floor portion 15 is set to a smaller value than the inclination angle α2 of the operation pedal portion 15b, and the tall person T Even when the area for placing the heel part Kt is set on the driver's seat side portion 15a or on a horizontal surface provided on the rear side thereof, the operability of the accelerator pedal 4 or the like is adversely affected. There is no.

  Even in the operation pedal side portion 15b of the inclined floor portion 15, if the inclination angle α2 is too steep, the collar portion placed on the operation pedal side portion 15b easily slips down when the pedal is operated. If α2 is too small, it is impossible to effectively prevent the short stature S from having the buttocks Ks of the pedal operation foot separated from the floor surface, and the operability of the accelerator pedal 4 and the like can be reduced. Since the effect of improving cannot be obtained sufficiently, it is desirable to set the inclination angle α2 within a range of 25 ° to 15 °.

  When the portion where the tall person T places the heel part Kt of the pedal operating foot as described above is set on the driver seat side portion 15a of the inclined floor portion 15, the accelerator pedal 4 is depressed. Since the collar portion Kt is placed at a position away from the support shaft 17 installation portion, which is the pivot point of the pedal body 18 during operation, the amount of depression of the accelerator pedal 4 increases. As indicated by 17 imaginary lines, the insulator ball part Bt tends to shift to a lower position Bt ′ from an appropriate position formed by the upper part or the like on the convex surface part 23.

  For this reason, the tall person T tries to keep the buttocks Kt in contact with the proper position by moving the buttocks Kt forward, but at that time, the buttocks Kt When the inclination angle α1 at the driver seat side portion 15a of the inclined floor portion 15 that is the mounting position of the driver is large, the driver's buttocks Kt are pressed against the upper surface of the driver seat side portion 15a and a large sliding resistance acts. The driver may feel uncomfortable. However, as described above, the inclination angle α1 at the driver seat side portion 15a of the inclined floor portion 15 is set within a range of, for example, about 15 ° to 5 °, and the upper surface of the driver seat side portion 15a is set to the operation pedal side portion 15b. In contrast, when it is gently inclined, there is an advantage that it is possible to effectively prevent a sense of incongruity caused by a large sliding resistance acting on the flange Kt.

  Further, if the inclination angle α1 at the driver seat side portion 15a of the inclined floor portion 15 is too steep, the effect of reducing the sliding resistance when the heel portion Kt of the tall person T moves forward during the pedal operation is sufficient. On the other hand, if the inclination angle α1 at the driver seat portion 15a is too small, when the tall person M, whose sole dimensions are slightly smaller than the tall person T, operates the pedal, Since Km is in a state of being separated from the floor surface, there is a possibility that a delicate pedal operation may be hindered. Therefore, it is desirable to set the inclination angle α1 of the driver seat side portion 15a within the range of 15 ° to 5 °. .

  Moreover, in the said 1st Embodiment, since it was set as the structure which provided the intermediate | middle area | region 15c in which an inclination | tilt angle increases gradually as it shifts from the driver seat side part 15a of the inclination floor part 15 to the operation pedal side part 15b, in this intermediate | middle area 15c. Accordingly, when the tall person M moves the heel part Km back and forth and adjusts the placement height of the heel part to an appropriate value, the adjustment operation of the heel placement height can be performed without a sense of incongruity. That is, without providing the intermediate region 15c, when the driver's seat side portion 15a with a gentle angle and the operation pedal side portion 15b with a steep angle are directly connected, the inclination angle of the upper surface suddenly changes at the connecting portion. When the tall person M moves the heel part Km back and forth along the upper surface of the inclined floor part 15 and adjusts the placement height of the heel part, there is a sense of incongruity due to the occurrence of catching at the connection part. However, as described above, by providing the intermediate region 15c in which the angle gradually increases between the driver-side portion 15a having a gentle angle and the operation-pedal portion 15b having a steep angle, the above-mentioned uncomfortable feeling can be effectively prevented. can do.

  Furthermore, as shown in the first embodiment, a convex surface portion 23 made of a curved surface having a curvature radius R1 of, for example, about 100 mm to 200 mm, bulging to the driver's seat side (rear side) in a side view is used as the accelerator pedal. In the case of the provided structure, the pressing position of the accelerator pedal 4 can be changed smoothly and continuously by rolling the contact position of the shoe back surface along the convex surface portion 23. Accordingly, the lever ball portion of the accelerator pedal 4 is separated from the installation portion of the support shaft 17 provided at the lower end portion of the pedal body 18 of the accelerator pedal 4. Even if the convex portion 23 is displaced in the vertical direction according to the stepping operation, it is possible to effectively prevent the driver from feeling uncomfortable.

  As described above, a flat surface portion having a radius of curvature larger than that of the convex portion 23, for example, a flat surface extending linearly obliquely upward in a side view when the radius of curvature is set to infinity. Instead of the first embodiment in which the convex portion 24 is connected to the upper end portion of the convex surface portion 23, the entire upper portion of the pedal body 18 that constitutes the accelerator pedal 4 is changed as in the modification shown in FIG. It is also possible to form the convex portion 23a made of a curved surface having a predetermined radius of curvature R1. However, according to this configuration, when a tall person T whose foot sole size is large and whose toe portion is separated above the pedal body 18 depresses the accelerator pedal 4 with the pedal operation foot. In addition, since the toe portion and the lower portion are largely separated from the upper portion of the pedal body 18, it is impossible to perform the stepping operation in a state where the foot back surface is in contact with the pedal body 18 in a side view. In some cases, the driver may feel uneasy when operating the pedal.

  On the other hand, as shown in the first embodiment, when the flat surface portion having a larger radius of curvature than the convex surface portion 23 is provided at the upper end portion of the convex surface portion 23, the high As shown in FIG. 17, the tall person T performs the pedal depressing operation in a state where the back surface is in contact with both the convex surface portion 23 and the flat surface portion 24 of the pedal main body 18 as shown in FIG. 17. Therefore, the driver can depress the accelerator pedal 4 with a sense of security.

  The brake pedal 5 may have a so-called organ-type pedal structure that includes a lower end pivot part and a pedal body that swings and displaces with the lower end pivot part as a fulcrum, like the accelerator pedal 4. As shown in FIG. 5, when a so-called suspension pedal type brake pedal 5 having a pedal body 46 supported so as to be swingable with the upper end pivot portion 44 as a fulcrum is provided, the brake pedal can be configured with a simple configuration. 5 can be supported stably, and the operability can be maintained in a good state.

  Further, in the first embodiment, as shown in FIG. 6, at least the rear part of the floor mat 14 is fixed to the floor panel 9 by, for example, being locked to the surface material 11 of the floor carpet 12 by the fastening tool 41. Therefore, there is an advantage that the floor mat 14 can be stably installed with a simple configuration. That is, in a state where the driver's lower limb is placed on the floor mat 14, a load in the direction of mainly pushing the floor mat 14 acts forward, so that at least the rear portion of the floor mat 14 is fastened to the fastener. For example, there is an advantage that a stable installation state can be obtained by effectively restricting the movement of the floor mat 14 by locking with 41 or the like.

  In addition, the front portion of the floor mat 14 may be configured to be fixed to the floor panel 9 via a predetermined fastening device or the like in a state where the front portion of the floor mat 14 is placed on the attached portion including the horizontal surface portion 16. Of course. Even in this case, it is possible to easily perform the fixing work with the fastening tool or the like in a state where the front portion of the floor mat 14 is stably placed on the attached portion including the horizontal surface portion 16.

  Further, in place of the mounted portion composed of the horizontal plane portion 16, a reverse inclined floor portion whose upper surface is inclined forward and downward is provided on the front side of the inclined floor portion 15, or the inclination is higher than the inclined floor portion 15. A gently inclined floor portion having a small angle may be provided, and the reversely inclined floor portion or the gently inclined floor portion may be configured as an attached portion to which the front portion of the floor mat 14 is attached. However, as shown in the first embodiment, when the structure is provided with a mounted portion made up of a horizontal surface portion 16 whose upper surface is formed horizontally, the front portion of the floor mat 14 is appropriately configured with a simple configuration. Can be attached.

  Moreover, in the said 1st Embodiment, the accelerator pedal 4 requested | required to perform delicate pedal operation in the state which mounted the buttocks of the pedal operation leg | foot on the upper side of the floor panel 9 of a compartment is provided in the floor panel 9. A so-called organ-type pedal comprising a fixed pedal base 19 and a pedal body 18 supported pivotally on a pivotal support portion 17 formed on the pedal base 19 and having a support shaft 17 is provided. Since the inclined floor portion 15 is disposed in the buttock placement region on the floor panel 9 on which the heel portion of the pedal operation foot is placed, regardless of the physique of the driver seated on the driver seat 1. There is an advantage that the pedal operation of the accelerator pedal 4 can be appropriately performed with a simple configuration.

  When the accelerator pedal 4 is depressed as described above, an upper surface is provided on the front side of the inclined floor portion 15 provided in the buttocks placement region on the floor panel 9 on which the buttocks of the pedal operation feet are placed. 15 is provided with a mounting portion of a floor mat 14 formed of a horizontal surface portion 16 formed on a substantially horizontal flat surface, the front portion of the inclined floor portion 15 as shown by the phantom line in FIG. A driver's buttocks Ks composed of a short stature S and the like placed on the pedal body 18 of the accelerator pedal 4 disposed on the front side of the horizontal surface portion 16 or a pedal base portion that supports the pedal body 18 A gap corresponding to the length of the horizontal plane portion 16 can be ensured between Therefore, when the short stature S or the like steps on the accelerator pedal 4 with the collar Ks placed on the inclined floor 15, the rear end of the pedal body 18 or the pedal base 19 is placed on the rear end. It is possible to effectively improve pedal operability by preventing the heel portion Ks of the pedal operation foot from interfering.

  Moreover, in the said embodiment, since it comprised so that it might install in the state which made the front-end part of the floor mat 14 contact | abut to the rear-end part of the pedal base part 19 which comprises the pedal main body 18 of the accelerator pedal 4, and positioned, There is an advantage that the fixing work can be easily and appropriately performed in a state where the movement of the front end portion of the floor mat 14 is restricted.

It is possible to perform delicate brake operation properly by touching.

  In addition, as described above, the inclination angle α1 at the driver seat portion 15a of the inclined floor portion 15 is set within a range of about 15 ° to 5 °, for example, and is gentler than the inclination angle α2 of the operation pedal portion 15b. Therefore, when the tall person T performs the depression operation of the brake pedal 5, the driver's buttocks Kt is prevented from being pressed against the upper surface of the inclined floor 15 so that the buttocks Kt There is an advantage that it is possible to prevent the occurrence of a sense of incongruity due to the large sliding resistance acting.

  For example, in the state where the tall person T places the heel portion Kt of the pedal operation foot on the driver seat portion 15a of the inclined floor portion 15, the slow brake operation state in which the depression amount of the brake pedal 5 is slightly changed. To the sudden braking operation state in which the amount of depression of the brake pedal 5 is increased, that is, at the time of braking addition operation, the depression Kt corresponding to the displacement of the depression operation portion 46a of the brake pedal 5 forward. By moving the vehicle forward, the driver ball along the upper surface of the driver-seat portion 15a when the lever ball portion Bt is kept in contact with the appropriate position of the stepping operation portion 46a. Since the driver can smoothly slide the collar portion Kt, the driver can appropriately perform the stepping operation of the brake pedal 5 without feeling uncomfortable.

  In the above embodiment, the heel portion placement area on the floor panel 9 on which the heel portion of the pedal operation foot for depressing the accelerator pedal 4 is placed, and the heel portion of the pedal operation foot for depressing the brake dall 5 are placed. Although the example which provided the inclination floor part 15 which inclined to the front rise by the same angle (alpha) 1, (alpha) 2, respectively was demonstrated in the collar part mounting area | region on the floor panel 9 in which a part is mounted is shown in FIG. 20 and FIG. As shown in the second embodiment, the inclination angle of the inclined floor portion 82 located in the accelerator pedal side region constituted by the heel pad material 13a and the inclined floor portion 83 located in the brake pedal side region are set to different values. May be.

  That is, in the second embodiment, the inclined floor portion 82 located in the accelerator pedal side region is divided into a driver seat side portion 82a and an operation pedal side portion 82b as in the first embodiment, and the front side thereof. A horizontal surface portion 16a having an upper surface formed on a substantially horizontal flat surface is formed. Then, an inclination angle α1 of the driver seat side portion (rear side portion) 82a is set within a range of 15 ° to 5 °, for example, and an inclination angle α2 of the operation pedal side portion (front side portion) 82b is set. The value is set larger than the inclination angle α1 of the driver seat side portion 15a, for example, in the range of 25 ° to 15 °.

  On the other hand, the inclined floor portion 83 located in the brake pedal side region has an overall inclination angle γ of the same angle as the inclination angle α1 of the driver seat side portion 82a in the inclined floor portion 82 of the accelerator pedal side region, That is, for example, a horizontal surface portion 16 b that is set within a range of 15 ° to 5 ° and whose upper surface is formed in a substantially horizontal flat surface is formed on the front side of the inclined floor portion 83. In this way, the inclination angle γ of the inclined floor portion 83 located in the brake pedal side region is set to a smaller value than at least the inclination angle α2 of the operation pedal side portion 82b in the accelerator pedal side region.

  In addition, between the inclined floor portion 82 located in the brake pedal side region and the driver seat side portion 83a of the inclined floor portion 83 located in the accelerator pedal side region, the difference in the inclination angles α1 and β is caused. A height difference is formed on the upper surface. A connecting portion 84 that smoothly connects the inclined floor portion 83 in the brake pedal side region and the inclined floor portion 82 in the accelerator pedal side region is formed in the operation pedal side portion 82b.

  When the accelerator pedal 4 and the brake pedal 5 are operated as described above, the heel portion placement area on the floor panel 9 on which the heel portion of the pedal operation foot composed of the right foot of the driver is placed is inclined upward. When the inclined floor portions 82 and 83 are provided and the inclination angle γ of the inclined floor portion 83 in the brake pedal side region is set to a smaller value compared to the inclined floor portion 82 in the accelerator pedal side region, A person who can properly depress the accelerator pedal 4 with the buttocks placed on the inclined floor portion 82, and also shifts from the operating state of the accelerator pedal 4 to the operating state of the brake pedal 5. There is an advantage that it is possible to effectively prevent the occurrence of a sense of incongruity caused by a large resistance generated at the buttocks of the pedal operating foot when the pedal is changed.

  That is, when the inclination angle γ of the saddle placement area on the brake pedal 5 side is set to be flat 0 °, when it is inclined upward 10 °, and when it is inclined upward 20 ° And a simulation analysis in which a driver having a height of about 160 cm, a driver having a height of about 170 cm, and a driver having a height of about 180 cm shift from the operating state of the accelerator pedal 4 to the operating state of the brake pedal, respectively. When the load generated on the buttocks of the pedal operating foot at that time, that is, the operation resistance was measured, data as shown in FIGS. 22 to 24 was obtained. 22 to 24, J1 indicates a time point when the pedal operation foot is released from the accelerator pedal 4, and J2 indicates a time point when the depression of the brake pedal 5 is started.

  From the above data, in the case of a driver having a height of about 160 cm, as shown in FIG. 22, it was confirmed that all can shift to the operating state of the brake pedal 5 without causing a large operating resistance in the buttocks. . This is considered to be because, in the case of the driver, since the sole dimensions are relatively short, the possibility that the buttocks are strongly pressed against the floor surface during the brake operation is low. On the other hand, in the case of a driver having a height of about 170 cm and a driver having a height of about 180 cm, the operation state of the accelerator pedal 4 is set when the inclination angle of the saddle placement region on the brake pedal 5 side is set to 20 °. It was confirmed that the driver feels uncomfortable when a large load is applied to the buttocks as shown in FIG. 23 (c) and FIG. .

  On the other hand, when the inclination angle γ of the saddle placement region on the brake pedal 5 side is set to 10 °, the operation of the accelerator pedal 4 is performed as shown in FIGS. 23 (b) and 24 (b). It has been verified that even when the state shifts from the state to the operation state of the brake pedal 5, a large load does not act on the buttocks and a sense of incongruity does not occur.

  Therefore, a driver having various physiques can appropriately depress the accelerator pedal 4 with the buttocks placed on the inclined floor portion 82, and the brake pedal 5 can be operated from the operation state of the accelerator pedal 4. In order to effectively prevent the occurrence of a sense of incongruity caused by the occurrence of a large resistance in the buttocks of the pedal operation foot when the pedal that changes to the operation state is changed, as shown in the second embodiment. Thus, it is desirable to set the inclination angle γ of the inclined floor portion 83 in the brake pedal side region to a smaller value compared to the inclined floor portion 82 in the accelerator pedal side region.

  Moreover, in the said embodiment, while moving the driver's seat 1 back and forth, the front-back position adjustment mechanism 2 and the inclination angle adjustment mechanism 3 which reduce the back inclination angle of the seat cushion 1a according to the front movement of this driver's seat 1. Therefore, the driver sitting on the driver's seat 1 appropriately sets the driving characteristics of the front / rear position adjusting mechanism 2 and the inclination angle adjusting mechanism 3 according to the height of the driver's seat 1 so that the driver's sitting posture While maintaining the above, the front and rear positions of the driver's seat 1 and the inclination angle of the seat cushion 1a are automatically adjusted so that the eye point coincides with the appropriate line L, and excellent handleability and pedal operability can be obtained. There is an advantage that it can be adjusted.

  Even when the seating position or the like of the driver seated on the driver seat 1 changes according to the adjustment operation of the front and rear position of the driver seat 1 and the inclination angle of the seat cushion 1a, the driver seat 1 is positioned at the feet of the driver. By forming the inclined floor portion 15 and the like on the floor panel 9 to be performed, the short stature person S having a short sole dimension places the heel portion Ks of the pedal operation foot on the inclined floor portion 15 and the like. In addition, while maintaining the ankle angle θ1 and the inclination angle θ7 of the sole of the foot at an angle suitable for the operation of the accelerator pedal 4 or the like, the above-mentioned palm ball portion Bs of the short stature S is applied to the convex surface portion 23 of the accelerator pedal 4 There is an advantage that the pedal operability can be secured by contact.

  In the above embodiment, the driver's seat 1 is automatically moved back and forth according to the driver's switch operation by the front / rear position adjusting mechanism 2 and the tilt angle adjusting mechanism 3, and the driver seat 1 is moved forward. In the example described above, the rearward tilt angle of the seat cushion 1a is reduced. However, the front / rear position of the driver's seat 1 and the rearward tilt angle of the seat cushion 1a are changed by the driver's manual operation. It may be configured.
