DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting a driving position of an automobile, and more particularly, the field of view of the front of the automobile is substantially constant even when drivers of different sizes sit in a driver's seat. The present invention relates to a driving position adjusting device for an automobile as described above.

[0002]

2. Description of the Related Art Conventionally, positions of a driver's seat (hereinafter, also simply referred to as "seat"), a steering wheel, and a driving pedal (hereinafter, also simply referred to as "pedal") are separately controlled by driving means. There have been proposed various devices that automatically move a driver to set a driving position (driving posture) of the driver in a favorable state.

For example, Japanese Patent Laying-Open No. 62-74766 discloses a device in which a driver takes a driving posture by gripping a steering wheel, turns on a switch, and moves and sets the steering wheel to an optimum position. . It is also conceivable that the position of the seat or the like for setting the driver to the optimal driving position is stored in the memory for each driver, and each time the driver changes, the position of the seat or the like is automatically adjusted based on the stored information. Have been.

[0004]

By the way, for example, when considering a person having a medium physique as a reference, when a driver having a small physique sits in a driver's seat, his eye position is too low, and an Whatever the size of the driver sitting in the driver's seat,
View ahead of the car (eg, how to see the hood), how to see meters, side view (how to see the beltline),
It is desired that the rear view is substantially common.

When the driving position is automatically set, the joint angles at various parts of the driver's body (wrists, elbows, hips, knees, ankles, etc.) must be controlled in order to ensure safe driving and prevent fatigue. It is also very important to maintain a stable state.

However, the above-described conventional driving position adjusting device cannot satisfy both of these requirements. In particular, in the conventional driving position adjusting device, the former requirement is not considered at all. Therefore, the present invention can automatically adjust the driving position so that the field of view in front of the vehicle as viewed from the driver's seat is substantially the same even if the physique of the driver changes, and the joint angle of the driver is reasonably stable. It is intended to provide a device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 shows the basic structure of a driving position adjusting device for an automobile according to a first embodiment of the present invention, and FIG. 2 shows a driver's seat provided with the adjusting device. As shown in FIG. 2, a driver 12 sitting on a driver's seat 11 of a vehicle 10 grasps a steering wheel 13 and desires to look outside the vehicle through a hood 15 through a front window 14. In FIG. 2, the driver 12 is schematically indicated by a skeleton, and a solid line, a broken line, and a dashed line indicate a driver having a relatively large, medium, and small physique, respectively.
12 (the same applies hereinafter).

In this embodiment, the driving operation pedal (in FIG. 2, an accelerator pedal is shown as an example) does not change its position or angle other than its original movement.

On the other hand, the driver's seat 11 has a mechanism shown in detail in FIG. 3 and is movable in the vehicle longitudinal direction. That is, a pair of left and right sliders 20 are held movably in the front-rear direction with respect to the vehicle body.
A seat bottom 21 is held against 20. Since the mechanism for holding the seat bottom 21 with respect to the slider 20 is bilaterally symmetric and equivalent to each other, only the mechanism on the left side of the vehicle body is shown in detail in FIG. 3 and will be described below.

Bearings 22 and 23 are joined to the upper surface of the slider 20 at a front portion and a rear portion, respectively. Seat bottom
The front part of 21 is rotatably attached to the bearing 22 by a bolt 24. On the other hand, a rear portion of the link 26 is rotatably attached to a rear portion of the seat bottom 21 by a bolt 25. The central portion of the link 26 is rotatably held by the bearing 23 by a bolt 27 and a nut 28.
A pin 31 passed through the guide groove 30 of the guide rail 29 is fixed to a front portion of the link 27. The guide groove 30 has a shape extending horizontally except for a front end portion extending forward and downward.

A block 32 having a female thread is fixed to the slider 20, and the block 32 is screwed to a screw rod 33 extending parallel to the slider 20. The screw rod 33 is rotated forward and reverse by a seat moving motor 35 via a gear box 34.

When the screw rod 33 rotates forward and backward as described above, the block 32 advances and retreats, and the slider 20 moves forward and backward. When the slider 20 moves back and forth, the seat bottom 21 and the seat back 36 held by the slider 20 move back and forth integrally. Here, when the seat bottom 21 is moved forward and the above-mentioned pin 31 gradually descends in the guide groove 30, the link 26 rotates around the bolt 27 in the direction of arrow A. So, the seat bottom 21 is bolted
It rotates about 24, and as shown by the dashed line in FIG.

Next, a mechanism for moving the steering wheel 13 for adjusting the driving position will be described with reference to FIG. As shown, the steering column 40 is swingable in the direction of arrow B about the tilt fulcrum 41. An upper tube outer tube 42 is slidably held in the longitudinal direction with respect to the steering column 40, and the upper tube inner tube 44 rotates via a bearing 43 with respect to the upper tube outer tube 42. It is kept possible. An upper shaft 45 is fitted and fixed to the upper tube inner tube 44, and the steering wheel 13 is attached to the upper shaft 45.

A lower shaft 46 is housed inside the upper tube inner tube 44, and both are engaged with serrations. Therefore, when the steering wheel 13 is rotated, the rotational force is transmitted to the lower shaft 46 via the upper shaft 45 and the inner tube 44 of the upper tube, and the rotation of the lower shaft 46 is transmitted to a steering gear or a joint (not shown). Is transmitted to the tie rod for turning the steered wheels.

On the other hand, a bracket 47 is fixed to the vehicle body. The bracket 47 has a curved guide groove 48 extending substantially in the front-rear direction of the vehicle body and gradually inclined upward toward the rear side. Another bracket 49 is fixed to the vehicle body, and a steering wheel moving motor 50 is attached to the bracket 49. The rotation shaft 50a of this motor 50 is
The rotation shaft 50a is connected to a shaft 52 through a shaft 51.
When the shaft rotates forward and backward, the shaft 52 moves in the front-back direction (the left-right direction in FIG. 4).

The shaft 52 has a pin extending in the vehicle width direction.
A pin 53 is fixed, and the pin 53 is inserted through a bracket 54 fixed to the steering column 40. A plate 55 is fixed to the tip of the shaft 52, and the plate 55 is connected to the upper tube outer tube.

In the above configuration, when the rotating shaft 50a of the steering wheel moving motor 50 rotates in one direction,
The shaft 52 moves forward to a position where the pin 53 contacts the front end of the guide groove 48 (position shown). In this state, the upper tube outer tube 42 and the inner tube 44 assume the front end position, and the steering wheel 13 comes to the position indicated by the one-dot chain line in FIG.

When the rotating shaft 50a of the steering wheel moving motor 50 rotates in the direction opposite to the above, the shaft 52 moves backward, so that the upper tube outer tube 42 and the inner tube
44 is pushed backward, and the steering wheel 13 gradually moves backward, that is, moves closer to the driver 12. At the same time, the pin 53 is guided by the guide groove 48 and moves upward, so that the steering column 40 swings around the tilt fulcrum 41 counterclockwise in the drawing. Therefore, the steering wheel 13 is displaced upward as it moves rearward.

Next, referring to FIG. 1, a description will be given of how the driver's seat 11 and the steering wheel 13 are moved in conjunction with each other. As shown, the sheet moving motor 35 is driven by a motor drive circuit 59, and the operation of the drive circuit 59 is controlled by a control unit 56 including, for example, a microprocessor or the like. control unit
To 56, a seat position operation switch 57 arranged, for example, on the side of the driver's seat 11 is connected, and by operating this switch 57, the driver 12 appropriately operates the motor 35, thereby driving the driver's seat. The position in the front-rear direction of the seat 11 can be set to an optimum position that matches the user's physique.

Driver's seat operated as described above
11 is detected by a linear gauge 58 (see FIG. 3) disposed below the seat bottom 21. The linear gauge 58 inputs a signal S1 indicating the position of the driver seat 11 in the front-rear direction to the control unit 56. The control unit 56 controls the position of the steering wheel 13 in the front-rear direction according to the signal S1.

That is, the control unit 56 stores the relationship between the seat front-rear position and the steering wheel front-rear position as shown in FIG. 5, for example, in the form of a map, and according to the map, the seat front-rear position indicated by the signal S1. Find the position of the steering wheel in the front-rear direction corresponding to. The control unit 56 sends an operation control signal S2 for setting the steering wheel 13 to this position to the motor drive circuit 60, controls the operation of the steering wheel moving motor 50 driven by the drive circuit 60, and The position in the front-rear direction of the wheel 13 is set to the position determined according to the above map.

As described above, the front-rear position of the steering wheel 13 is automatically adjusted in accordance with the front-rear position of the driver's seat 11 which can be changed according to the physique of the driver 12, as shown in FIG. The line of sight C of the driver 12 forms an almost constant angle with the hood 15 regardless of the physique. In such a case, the view ahead of the vehicle desired by the driver 12 does not change uniquely depending on the physique of the driver 12. The same applies to the side view and the rear view. And the wrist of driver 12,
The joint angles at the elbows, hips, knees, etc. can be maintained in a reasonably stable state.

In this embodiment, when the driver's seat 11 is moved to a position close to the front end position in accordance with the driver 12 having a relatively small size, the seat bottom is moved as described above.
Since the rear portion 21 rises, the above-described effects can be obtained particularly well. 2, a change in the hip point of the driver 12 due to the movement of the seat bottom 21 is indicated by an arrow D.

Further, in the present embodiment, the steering wheel 13 is gradually displaced upward as it is moved rearward, so that the above-described operation and effect can be obtained particularly well.

The moving mechanism of the driver's seat 11 is constructed as in the above-described embodiment. In addition, for example, when the driver's seat 11 moves forward, the entire driver's seat 11 moves upward at a constant rate of change (that is, FIG. 2). In such a case, the trajectory of the hip point of the driver 12 may be an oblique straight line rising leftward. In addition, the moving mechanism of the steering wheel 13 is configured as in the above embodiment, and the guide groove 48 shown in FIG. May be configured to move upward.

Next, a second embodiment of the present invention will be described with reference to FIGS. In FIG. 6 and subsequent figures, the same elements as those already described are denoted by the same reference numerals, and description thereof will be omitted unless particularly necessary (the same applies hereinafter).

In this second embodiment, as shown in FIG. 7, the position of the steering wheel 13 is fixed. On the other hand, the driver's seat 11 is basically formed in the same manner as in the first embodiment, but its front-back movement stroke is set relatively short. The accelerator pedal 16 can be moved back and forth together with a brake pedal (not shown in FIG. 7).

A mechanism for moving the pedal will be described below with reference to FIGS. In this embodiment, the present invention is applied to a so-called automatic vehicle having only an accelerator pedal 16 and a brake pedal 61 as driving operation pedals. The accelerator pedal 16 and the brake pedal 61 are respectively attached to a shaft 63,
It is swingably held around 64.

The engagement portion 16a of the accelerator pedal 16 has a pin
The lower end portion of the connecting member 66 is engaged via 65. The connecting member 66 is held swingably about a shaft 67 with respect to the pedal bracket 62, and one end of a throttle wire 68 is fixed to an upper end thereof. This throttle wire
68 is inserted into a flexible tube 70 slidably held with respect to a dash lower panel 69, and the other end is connected to a throttle valve (not shown). Therefore, when the accelerator pedal 16 is depressed, the movement is transmitted to the throttle valve via the throttle wire 68.

On the other hand, a wire is
71 are linked. This wire 71 is also a flexible tube 72
It is inserted inside. One end of this tube 72 is
The other end is fixed to the outer surface of the main body of the booster 74. break pedal
When the pedal 61 is depressed, the movement is transmitted to the piston in the master cylinder 75 via the wire 71.

As an example, four hollow sliders 76 are fixed to the pedal bracket 62, and a guide rod 77 fixed horizontally to a dash lower panel 69 is slidably inserted into each of the sliders 76. ing. At the same time, guide blocks 78 and 79 fixed to the upper and lower portions of the pedal bracket 62, respectively, are slidably engaged with guide rails 80 and 81 fixed horizontally to the vehicle body, respectively. Thus, the pedal bracket 62 is movable in the front-rear direction (the left-right direction in FIG. 8) with respect to the vehicle body.

Driving members 82 and 83 having, for example, a rack portion are fixed to the upper and lower portions of the pedal bracket 62, respectively. Each of the drive members 82 and 83 is moved in the forward and backward directions by the pinions 88 and 89 meshing with the rack portion being rotated forward and reverse through gear boxes 86 and 87 by pedal movement motors 84 and 85, for example. It is possible to reciprocate. The movement of the driving members 82 and 83 causes the pedal bracket 62 to move in the front-rear direction. Note that FIG.
FIG. 9 shows a state in which the pedal bracket 62 moved as described above is at the front end position, and FIG. 9 shows a state in which the pedal bracket 62 is at the rear end position.

As shown in FIG. 6, also in this embodiment, the front / rear position adjustment of the driver's seat 11 is performed in the same manner as in the first embodiment. Then, a signal S1 indicating the position of the driver's seat 11 in the front-rear direction is input from the linear gauge 58 to the control unit 56A.
A sets the position of the pedal bracket 62 in the front-rear direction (that is, of the two pedals 16, 61) in correspondence with the detected seat front-back position.

That is, in this case, the operation control signal S3 corresponding to the signal S1 is input from the control unit 56A to the motor drive circuit 90, and the two pedal moving motors 84 and 85 are driven in accordance with the signal S3. Thus both pedals 1
6, 61 are set to the rear position as the seat position comes to the front. Thereby, also in this case, the field of view in front of the vehicle, the side field of view, the rear field of view and the like desired by the driver 12 are kept substantially constant regardless of the physique of the driver 12, and
The joint angles at 12 elbows, hips, knees, ankles, etc. will also be reasonably stable. In addition, it is sufficient for the range of movement of the pedals in the front-back direction to be practically secured, for example, about 80 mm.

In the above embodiment, the angle between the two pedals 16 and 61 is kept constant regardless of the front and rear positions. However, generally, these pedals 16 and 61 are arranged more rearward. As the angle of the ankle of the driver 12 becomes steeper, the angle may be changed according to the position in the front-rear direction of the pedal in order to eliminate this point.

FIG. 10 shows an example of the mechanism described above. In FIG. 10, only the moving mechanism of the accelerator pedal 16 is shown. Pedal bracket 62
, A slider 91 is fixed, and the slider 91 is movable on the floor panel 92 in the front-rear direction (left-right direction in the figure) by a driving mechanism (not shown). The swing shaft 63 of the accelerator pedal 16 is movably engaged in a guide groove 93 formed in the slider 91 in the front-rear direction.

One end of a wire 94 is fixed to the swing shaft 63, and the wire 94 is connected to a pin 95 fixed to the slider 91.
And the other end is fixed to the floor panel 92. Further, the other end of the coil spring 96 having one end hooked to the lower portion of the accelerator pedal 16 is hooked to the pedal bracket 62, whereby the accelerator pedal 16 is biased in a direction in which the lower portion moves forward.

In the above configuration, when the accelerator pedal 16 is set at the front end position (the position indicated by the solid line in the drawing), the accelerator pedal 16 is in a state of standing at a relatively steep angle due to the urging action. On the other hand, as the accelerator pedal 16 is moved backward, the swing shaft 63 is pulled backward by the wire 94, so that the accelerator pedal 16 stands at a gentler angle.

The angle range of the accelerator pedal 16 that can be changed as described above is practically sufficient if, for example, about 20 ° is secured. Further, as described above, in addition to changing the angles of the pedals in the front-rear direction, the positions of the pedals in the vertical direction can be changed in the front-rear direction.

Next, a third embodiment of the present invention will be described with reference to FIGS. In this embodiment, a steering wheel moving mechanism similar to that shown in FIG.
A pedal movement mechanism similar to that shown in FIGS. 8 and 9 is provided. In the present embodiment, as shown in FIG.
The driver's seat 11 cannot move in the front-back direction, but can move in the up-down direction.

Hereinafter, the seat vertical movement mechanism will be described.
This will be described with reference to FIG. Holders 102 are fixed to a pair of left and right attachment members 101 to which the seat bottom 21 is attached, respectively, at front and rear ends.
Each of 2 has a connecting member 103 held therein. Each connecting member
103 is fixed to the tip of a vertically arranged screw rod 104. Each screw rod 104 is a gear box
Inside 105, it is screwed into a female screw member (not shown) rotated by the sheet moving motor 35B. When the female screw member is rotated forward and reverse, each screw rod 104
Reciprocates, the seat bottom 21 moves in the up-down direction.

As shown in FIG. 11, the control unit
When the seat position operation switch 57B connected to 56B is operated, the motor for driving the seat 35
B is driven, and the vertical position of the driver's seat 11 is changed. Thus, for example, the driver 12 having a relatively small physique can set the driver's seat 11 at a higher position.

The vertical position of the driver's seat 11 is determined, for example, by the linear gauge 58 incorporated in the gear box 105.
B. The signal S4 indicating the vertical position of the seat is input to the control unit 56B.
The control unit 56B outputs operation control signals S2 and S3 corresponding to the signal S4 to the motor drive circuits 60 and 90, respectively.
To adjust the position of the steering wheel 13 in the front-rear direction and the position of the pedal bracket 62 in the front-rear direction.

That is, in this embodiment, as the position of the driver's seat 11 is higher, the pedal bracket 62 (that is, both pedals 16 and 61) is set at a more rearward position, and the steering wheel 13 is set at a more rearward position. You. By doing so, also in the present embodiment, the field of vision in front of the vehicle, the side field of view, the rear field of view and the like desired by the driver 12 are kept substantially constant irrespective of the physique of the driver 12, and the wrist of the driver 12 is maintained. The joint angles at the elbows, waist, knees, ankles, etc. are also reasonably stabilized. Note that it is sufficient for the vertical movement range of the driver's seat 11 to be practically secured, for example, about 50 mm.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. In this embodiment, a seat moving mechanism similar to that shown in FIG. 3 and a steering wheel moving mechanism similar to that shown in FIG. 4 are provided.

In addition, in this embodiment, a pedal moving mechanism for changing the pedal angle is provided. Hereinafter, this pedal moving mechanism will be described with reference to FIG. The brake pedal 61 and the accelerator pedal 16 are each swingably held by pedal brackets 110 and 111 fixed to a dash lower panel 69. A bracket 112 is fixed to the vehicle body below the accelerator pedal 16. A guide groove 113 extending in the front-rear direction of the vehicle body is formed in the bracket 112, and a pin 114 fixed near the lower end of the accelerator pedal 16 is movably accommodated in the guide groove 113. .

The lower end of the accelerator pedal 16 has a shaft 11
The driving member 83 is connected so as to be able to swing around the center 5. When the driving member 83 is moved in the vehicle longitudinal direction by the pedal moving motor 85, the lower portion of the accelerator pedal 16 moves between the solid line display position and the dashed line display position, so that the pedal angle changes. .

As shown in FIG. 14, the control unit 56C inputs the operation control signals S2 and S5 corresponding to the output signal S1 of the linear gauge 58 to the motor drive circuits 60 and 90, respectively, and The position of the steering wheel 13 and the angle of the accelerator pedal 16 are changed according to the position. That is, in this case, as shown in FIG. 15, the driver's seat 11 is set at a more forward position because the physique of the driver 12 is relatively small, and therefore, the steeper the angle below the driver's knee, the more the accelerator pedal 16 Is changed to be smaller.

In the first embodiment shown in FIG. 2, the ankle joint angle of the driver 12 may be slightly unreasonable. In the fourth embodiment, the pedal angle is changed as described above. In addition, the above-mentioned slight problems can be prevented.

Next, a fifth embodiment of the present invention will be described with reference to FIGS. In this embodiment, a seat moving mechanism similar to that shown in FIG. 3, a mechanism for moving the pedals back and forth and up and down, and a mechanism for moving the steering wheel 13 in the front and rear directions while tilting are provided. Have been.

First, the pedal moving mechanism will be described with reference to FIGS.
This will be described with reference to FIG. This pedal moving mechanism is a slider

When the levers 84 and 85 are actuated and the pedal bracket 62 moves to the rear end position shown in FIG. 20, the pedal bracket 62 (that is, both pedals 16 and 61) gradually moves upward along the guide rod 77. I will be.

Next, the steering wheel moving mechanism will be described with reference to FIG. In this configuration, the upper portion of the steering column 40 can be tilted about the tilt shaft 120. A steering wheel moving (tilt) motor 121 is provided on the lower left side (front side in the figure) of the steering column 40, and the rotation of the motor 121 is transmitted via a gear box 122 to a tilt rod 125.
Is converted to forward and backward movement. This tilt rod 125 has
A connecting member 128 is connected via a swing shaft 127, and the connecting member 128 is connected to an upper portion of the steering column 40. Therefore, as described above, the tilt rod
When the 125 moves back and forth, the upper portion of the steering column 40 performs a tilt operation.

Further, on the lower right side of the steering column 40, a steering wheel moving (sliding) motor 12 is provided.
3 and the rotation of the motor 123
Is converted into forward and backward movements of the sliding rod 126. The tip of the rod 126 is connected to the outer tube 42 via a connecting member 129. Therefore, when the sliding rod 126 moves back and forth as described above,
The steering wheel 13 moves forward and backward.

As shown in FIG. 17, the control unit 56D inputs operation control signals S2 and S3 corresponding to the output signal S1 of the linear gauge 58 to the motor drive circuits 60 and 90, respectively, and the front and rear directions of the driver's seat 11 The position of the steering wheel 13 and the positions of the pedals 16 and 61 are changed according to the position. That is, in this case, as shown in FIG. 18, the smaller the size of the driver 12 and the more the driver's seat 11 is set at a more forward position, the more the steering wheel 13
Is set to a position where it slides more forward and tilts upward, while both pedals 16 and 61 are set to a position further backward and upward. By doing so, the driver 12
The joint angle of the ankle and wrist becomes more stable without difficulty.

The pedals 16, 61 may be moved back and forth and up and down as described above, or may be moved back and forth and the angle thereof may be changed.
It is also possible to configure such that both pedals 16, 61 move only in the front-back direction.

In order to raise the rear portion of the seat bottom 21 when the driver's seat 11 moves forward near the front end position, in addition to the mechanism shown in FIGS.
