Description

  The present invention relates to a driving posture adjusting apparatus configured to be able to adjust the driving posture of a driver seated on a driver seat.

Conventionally, for example, as shown in Patent Document 1 below, a driver operates a switch to move a driver seat to a preset standard position before sitting on the driver seat, and then sits on the driver seat. The driver operates the switch to adjust the front / rear position (longitudinal position) of the driver's seat, the inclination of the seat back, and the vertical position of the seat cushion (vertical position of the seat) The driver's seating position, seating posture, and the like are adjusted to be suitable for driving operation.
Japanese National Patent Publication No. 10-512214

  In the element position adjustment system for an automobile disclosed in Patent Document 1, for example, when the height of a driver sitting on the driver's seat is lower than the standard height, the driver's seat is moved forward from the standard position. Therefore, the front and rear positions of the driver seat are adjusted according to the length of the driver's feet so that the operation pedal including the accelerator pedal disposed in front of the driver seat can be properly operated. Thereafter, the seating posture can be made easier by adjusting the inclination of the seat back, and the front view can be appropriately secured by adjusting the vertical position of the seating surface.

  However, after adjusting the front / rear position of the driver's seat as described above, the seating posture of the driver seated on the driver's seat changes if the tilt of the seat back and the vertical position of the seating surface are adjusted. Correspondingly, the operability with respect to the operation pedal may be deteriorated, and the front and rear positions of the driver seat must be adjusted again in order to ensure the operability of the operation pedal. If the front-rear position of the driver seat is readjusted, the seating posture may deviate from the appropriate state, or the driver's eye point may deviate from the appropriate line and the forward visibility may deteriorate. Thus, there is a problem that the inclination of the seat back and the vertical position of the seat surface must be adjusted again.

  In addition, in order to avoid the complexity of the above readjustment, the front and rear position of the driver's seat, the inclination of the seat back, the vertical position of the seat surface, and the like are adjusted at the same time with a preset correspondence relationship. However, in this case, if you want a seating posture according to the user's preference, etc., that is, if you want a seating posture that deviates from the above correspondence according to long-time driving style, physical characteristics, etc. There is a problem that the sitting posture cannot be obtained.

  In view of the above circumstances, an object of the present invention is to provide a driving posture adjusting device that can easily and appropriately adjust the driving posture of a driver seated on a driver seat.

  For example, when a later-described main operation switch is operated in the forward direction, a control signal for normal rotation of the drive motor 46 is output, and the drive motor 46 rotates forward in response to the control signal. A driving force in the direction of moving the seat cushion 1a forward is transmitted to the drive shaft 47, the power transmission unit 49, and the rotation shaft 45. The rotating shaft 45 is supported by a nut block 41a fixed to the bottom of the seat slide lower rail 41, and is rotationally driven by the driving force input from the power transmission portion 49 and screwed forward to the vehicle body. As a result, the seat cushion 1a of the driver's seat 1 together with the seat slide upper rail 42 is driven to the front side of the vehicle body.

  On the other hand, when the main operation switch is operated in the backward direction, a control signal for reversely rotating the drive motor 46 is output, and the drive motor 46 reversely rotates in response to the control signal, whereby the seat cushion 1a. The driving force in the direction of reversing the vehicle is transmitted to the drive shaft 47, the power transmission unit 49, and the rotation shaft 45, and the rotation shaft 45 is driven in reverse and screwed to the rear side of the vehicle body, whereby the seat slide upper rail 42 and the seat cushion 1a of the driver's seat 1 are driven to the rear side of the vehicle body.

  Further, the seat slide lower rail 41 is installed on the vehicle body floor portion 8 in a state of being inclined forward and forward at a predetermined angle (for example, about 5 °). When the seat cushion 1a of the driver's seat 1 is moved to the front side of the vehicle body along the seat slide lower rail 41, the seat cushion 1a is pushed upward in conjunction with this. Conversely, when the seat front / rear position adjusting mechanism 2 moves the seat slide upper rail 42 and the seat cushion 1a of the driver's seat 1 to the rear side of the vehicle body along the seat slide lower rail 41, the seat is interlocked therewith. The cushion 1a is lowered.

  The seat slide upper rail 42 is provided with a seating surface adjusting mechanism 3 that drives the seat cushion 1a of the driver seat 1 to move up and down and to change the inclination angle of the seating surface. As shown in FIGS. 6 and 7, the seat surface adjustment mechanism 3 is installed on the cushion frame 51 provided on the left and right side portions of the seat cushion 1 a and the upper surface of the front portion of the seat slide upper rail 42. A front bracket 52 and a front link 53 that support the front end portion of the frame 51, a rear bracket 54 that is installed on the rear upper surface of the seat slide upper rail 42 and supports the rear portion of the cushion frame 51, and a triangular rear link 55, a connecting shaft 56 that connects the rear end portions of the left and right rear links 55 and the rear lower ends of the cushion frames 51, and an upper surface of the center portion of the seat slide upper rail 42 to be attached to the rear links 55. A central link 57 for transmitting a driving force and a central bracket 58 for supporting the central link 57; The connecting link 59 to the upper link 57 is connected to the front end portion of the rear link 55, following the drive shaft 60, and a drive lever 61 and the tilting drive unit 62.

  The central link 57 is fixed to a drive shaft 60 whose lower end extends in the vehicle width direction, and is rotatably supported by the central bracket 58 via the drive shaft 60. A drive lever 61 is fixed to the drive shaft 60 so as to rotate and displace the drive shaft 60. Further, the central bracket 58 provided on one of the pair of left and right seat slide upper rails 42 (the outer side in the vehicle width direction) is provided with a tilt drive unit 62 that drives the drive lever 61 fixed to the drive shaft 60. Is provided.

  As shown in FIGS. 9 and 10, the tilt drive unit 62 includes a screw shaft 64 having a front end portion connected to a tip end portion (lower end portion) of the drive lever 61 via a connection pin 63, and the screw shaft 64. And a guide bracket 67 fixed to the front surface of the gear mechanism 66, and a base end portion of the guide bracket 67 is connected to the central bracket 58 via a support bracket 68. It is supported by. The gear mechanism 66 is provided with a worm gear 69 fixed to the output shaft 65a of the drive motor 65, and a worm nut 70 that is rotationally driven by the worm gear 69. A screw hole that is screwed into the shaft 64 is formed.

  Then, as the worm nut 70 is rotationally driven by the driving force input from the drive motor 65 through the worm gear 69, the screw shaft 64 screwed to the worm nut 70 is rotated and screw-fed. It has become so. As the screw shaft 64 is screwed, the connecting pin 63 provided at the tip of the screw shaft 64 moves back and forth along the support groove 71 formed in the guide bracket 67, and the driving force thereof is connected to the connecting pin 63. By being transmitted to the drive lever 61 via this, the drive lever 61 is oscillated and displaced, and the drive shaft 60 is rotationally driven.

  Further, as the drive shaft 60 is rotationally driven, the central link 57 is oscillated and displaced, and the driving force is transmitted to the rear link 55 via the connecting link 59, and the rear link 55 is oscillated. In addition to the dynamic displacement, the front link 53 is oscillated and displaced in response to this, whereby the seat cushion 1a is driven up and down to adjust the vertical position of the seat surface. That is, in the state where the seat cushion 1a of the driver's seat 1 is located on the rear side of the vehicle body, the front link 53 and the center link 57 are inclined rearward as shown in FIG. When the connecting shaft 56 provided at the rear end portion is positioned below, the seat surface of the seat cushion 1a is held in a state of being inclined backward at a predetermined angle.

  In the above configuration, as will be described later, when the operation of moving the driver's seat 1 to the front side of the vehicle body is performed by the main operation switch, the seat surface adjustment is performed based on the basic control characteristics described later. A control signal for normally driving the drive motor 65 of the mechanism 3 is output from the main control means, and the forward drive force of the drive motor 65 is the gear mechanism 66, the screw shaft 64, the connecting pin 63, the drive lever 61, and the drive shaft. The central link 57 is transmitted to the central link 57 through 60, and the central link 57 shifts from the rearward tilt state to the standing state as shown in FIG. Then, as the central link 57 shifts to the standing state, the driving force is transmitted to the rear link 55 via the connecting link 59, and the front end portion of the rear link 55 is pulled to the front side of the vehicle body. The connecting shaft 56 provided at the rear end portion of the rear link 55 is lifted as indicated by an arrow, and the rear end portion of the seat cushion 1a is driven to be pushed forward obliquely in accordance with this.

  Further, when the front link 53 shifts from the rearward tilted state to the standing state in conjunction with the swinging displacement of the rear link 55, the upper end pivotal support portion is driven in the direction indicated by the arrow. The front end of the seat cushion 1a is driven to move forward while being pushed up, and the seat cushion 1a is displaced from the lowered position shown in FIG. 6 to the raised position shown in FIG. Furthermore, the backward movement angle of the seat surface according to the upward movement of the seat cushion 1a is set by setting the upward movement amount of the rear end part larger than the upward movement amount of the front end part of the seat cushion 1a. The driver's hip point (seat center point) H located on the seat surface of the driver's seat 1 is slanted as shown by an arrow while being gradually reduced and driven to approach the horizontal state. The seatback 1b is driven so as to move forward, and in conjunction with this, the inclination angle of the seat back 1b changes 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 main operation switch, a control signal for driving the drive motor 65 of the seat surface adjustment mechanism 3 in the reverse direction based on the basic control characteristics. Is output from the main control means, and the forward driving force of the driving motor 65 is transmitted to the central link 57 via the gear mechanism 66, the screw shaft 64, the connecting pin 63, the driving lever 61 and the driving shaft 60. As a result, the seat cushion 1a is displaced from the raised position shown in FIG. 11 to the lowered position shown in FIG. 6, and the rearward inclination angle of the seat surface is gradually increased in accordance with the downward movement of the seat cushion 1a. In addition, the seat back 1b is configured to be largely inclined backward.

  As shown in FIG. 12, the driving posture adjusting device instructs the main operation switch 81 that instructs to move the driver's seat 1 back and forth and finely adjust the vertical position of the seat surface of the driver's seat 1. The vertical position adjustment switch 82, the front / rear position adjustment switch 83 for instructing fine adjustment of the front / rear position of the seat surface of the driver's seat 1, and the tilt angle of the seat back 1b of the driver's seat 1 are adjusted by tilting displacement. And a seat back switch 84 for supporting the operation, and these are arranged on a switch panel provided in a console box or an instrument panel.

  The output signal of the main operation switch 81 is input to the main control means 85, and the driver's seat 1 is moved back and forth based on basic control characteristics preset in the main control means 85 and the vertical position of the seat surface is adjusted. Control to be executed. Further, the output signal of the vertical position adjustment switch 82 or the front / rear position adjustment switch 83 is input to the sub-control means 86, and the sub-control means 86 sets the seat surface of the driver's seat 1 in the first and first preset positions. Control that moves along two reference lines is executed.

  The main operation switch 81 includes a toggle switch that can be operated in two directions to instruct the driver seat 1 to move forward or backward when the operation unit is pushed in the front-rear direction. Further, the vertical position adjustment switch 82 and the front / rear position adjustment switch 83 instruct to move the seat cushion 1a of the driver's seat 1 back and forth or up and down by operating the operation unit in the up and down direction or the front and back direction. It consists of a toggle switch that can be operated in four directions. Further, the seat back switch 84 is a toggle switch that can be operated in two directions to instruct to displace only the seat back 1b of the driver's seat 1 independently by tilting the operation lever in the front-rear direction. Etc.

  While the main operation switch 81 is being pushed, an operation command signal for causing the drive motor 46 of the seat front / rear position adjustment mechanism 2 to rotate forward or reverse is output from the main control means 85. Further, the main control means 85 operates the seat surface adjustment mechanism 3 in conjunction with the front and rear position of the driver seat 1 in accordance with the operation of the main operation switch 81, thereby operating in advance. Based on the set basic control characteristics, the seat surface of the driver's seat 1 is moved up and down to adjust its vertical position, and the seat cushion 1a and the seat back 1b are tilted and displaced integrally to change the tilt angle. It is configured as follows.

  That is, 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. Corresponding to the above, the operability of the driver sitting on the driver's seat 1 with respect to the eye point I, the operation pedal, and the like also changes. Therefore, the driver who newly sits on the driver's seat 1 can hold the steering handle 20 in an appropriate state while maintaining the comfortable posture, and the operating foot of the operating pedal including the accelerator pedal 5 can be depressed. The insulator ball part can be brought into contact in an appropriate state, and the eye point I is made to coincide with an appropriate line L set so as to connect the lower end part of the windshield and the upper surface of the bonnet, for example. The front and rear position adjustment mechanism 2 and the seat surface adjustment mechanism 3 are operated to adjust the front and rear position of the driver's seat 1 and the like so as to ensure appropriateness.

  Since the driver seat 1 may be seated by drivers having various heights from those with a height of less than 150 cm to those with a height of 186 cm or more, these people can sit on the driver seat 1 in an easy posture. Therefore, it is necessary to configure so that the driving operation can be performed properly. For example, in the United States, the height of the average height person M who is considered to have the most opportunity to sit on the driver's seat 1 is set to 173 cm based on the average value of American men, and the comfort posture of the average height person M is statistically determined. As a result of analysis, the following data was obtained.

  The comfortable posture of the driver seated on the driver seat 1 is a seating posture that can 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. 13, the ankle angle θ1 of the operating 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 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 20 can be properly operated is about 100 ° to 130 °, the side angle θ6 is about 20 ° to 45 °, and the accelerator pedal 5 can be appropriately operated. The sole angle of the operating foot, that is, the inclination angle θ7 of the sole with respect to the horizontal line is about 52 °.

  Accordingly, the average height person M sets, for example, the ankle angle θ1 of the operation foot to 90 °, the knee angle θ2 to 125 °, and the bending angle θ3 between the upper body and the thigh from the hip to the shoulder to 95 °. In addition, 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 is made to coincide with the appropriate line L inclined forward and downward at an angle of about 8 °. In addition, the elbow angle θ5 and the armpit angle θ6 are set within the above range so that the steering handle 20 can be properly gripped, and the buttocks Km of the operating foot are set in advance as a reference position. The seat cushion 1a can be brought into contact with the stepping point 5a of the accelerator pedal 5 at the appropriate angle θ7 (52 °) while the seat cushion 1a is placed on the accelerator pedal 5, and the vertical height thereof. And tilt angle , Calculated based on the design data of the human body model and driving posture adjusting device, before and after the reference position of the value driver seat 1 is set as a reference vertical position and the reference tilt angle of the seat surface. Then, using the hip point (sitting reference point) Hm of the average height person M seated on the seating surface installed at the reference position as the reference position of the basic control characteristics, the reference control characteristic P is set as shown in FIG. To plot it on the graph.

  When the driver sitting on the driver's seat 1 changes from the average stature M to a short stature S consisting of a female driver or the like, as shown by the phantom line in FIG. 13, the short stature S The seat front / rear position adjustment mechanism 2 and the seat surface adjustment mechanism 3 are operated so that the eye point Is can coincide with the appropriate line L while ensuring the handle operability and the pedal operability, and the seat cushion of the driver's seat 1 While moving 1a ahead, the operation which raises the installation height of the seat cushion 1a corresponding to this, and reduces the inclination-angle of the seat cushion 1a with respect to a horizon is performed.

  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 1 a is set a predetermined distance from the reference position Hm for the average height person M. In conjunction with this, the hip point Hs is moved upward by a predetermined distance, and the tilt angle of the seat cushion 1a is changed so as to decrease the roll angle θ4. By this operation, the upper body of the short stature S having a short hand compared to the average height M can be moved forward to hold the steering handle 20 in an appropriate state, and the sitting height is lower than that of the average height M. By moving the eye point Is of the short stature S to the upper front side of the vehicle body, the front / rear position, the vertical height, and the inclination angle of the seat cushion 1a that can be matched with the appropriate line L are determined based on the human body model. And obtained based on the design data of the driving posture adjusting device and the like, and this value is set as the foremost position of the driver's seat 1, the uppermost position of the seat surface and the minimum inclination angle. Then, using the hip point (sitting reference point) Hs of the short stature S seated on the seating surface installed at the above position as the forefront position of the basic control characteristics, the reference control characteristic P is set as shown in FIG. Plot on the graph to do.

  Further, since the operation 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. By increasing the angle, the ankle angle θ1 of the operation foot is maintained at 90 °, and the inclination angle θ7 of the sole is maintained at an appropriate angle (52 °), while the short stature S has the palm ball portion of the operation foot. Bs can be brought into contact with the depression point 5a of the accelerator pedal 5.

  As shown in FIG. 14, the distance (about 15.5 cm) from the buttocks Ks of the short stature S to the palm ball part Bs is about the same as that of the average stature M (about 18.0 cm). Since the short stature S maintains the ankle angle θ1 of the operating foot and the inclination angle θ7 of the sole at the above angle (52 °), the lever ball portion Bs is depressed by the accelerator pedal 5 because it is 2.5 cm short. If it is going to maintain in the state contact | abutted to 5a, it is necessary to position about 2 cm (= sin52 degrees x 2.5 cm) of the heel part Ks of the operation foot from the heel part Km of the average height person M .

  In the above embodiment, since the second inclined surface portion 13 in which the upper surface 16 is inclined upwardly at an inclination angle β of 10 ° to 15 ° is formed in the heel mounting region of the operating foot located behind the accelerator pedal 5, As shown by the phantom line in FIG. 14, the short stature person S sitting on the seat seat 1 places the heel part Ks of the operation foot on the second inclined surface part 13, and the palm ball part of the operation foot By bringing Bs into contact with the stepping point 5a of the accelerator pedal 5, the stepping operation can be performed appropriately.

  On the other hand, as shown in FIG. 15, when a tall person T having a height of, for example, 186 cm sits on the driver's seat 1, the hip point Ht located on the seat cushion 1a is given to the average height person M. The seat cushion 1a is moved backward from the corresponding reference position Hm by a predetermined distance, and in conjunction with this, the hip point Hs is moved downward by a predetermined distance and the rhino angle θ4 is increased by 20.0 °. Operate to change the inclination angle. By this operation, the upper body of the tall person T having a longer hand than the average tall person M can be moved rearward to hold the steering handle 20 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, the front / rear position, the vertical height and the inclination angle of the seat cushion 1a that can be matched with the appropriate line L are determined based on the human body model and This value is determined based on design data of the driving posture adjusting device, and this value is set as the foremost position of the driver's seat 1, the uppermost position of the seat surface, and the minimum inclination angle. Then, the reference control characteristic P is set as shown in FIG. 17 with the hip point (sitting reference point) Ht of the tall T seated on the seating surface installed at the above position as the last position of the basic control characteristics. Plot on the graph to do.

  Further, since the operating foot of the tall person T tends to move downward in the rear part of the vehicle body in accordance with the backward and downward movement of the seat cushion 1a, the knee angle θ2 is reduced to about 120 ° correspondingly. As a result, while maintaining the ankle angle θ1 at 90 ° and maintaining the inclination angle θ7 of the sole at an appropriate angle of about 52 °, the accelerator ball 5 is depressed by the accelerator pedal 5. It can be brought into contact with the point 5a.

  In addition, as shown in FIG. 16, the distance (about 19.5 cm) from the buttocks Kt of the tall person T to the palm ball part Bt is larger than the same distance (about 18.0 cm) of the average tall person M. The tall person T maintains the ankle angle θ1 of the operating foot and the inclination angle θ7 of the sole of the foot at the above angles, and the lever ball portion Bt is used as a depression point 5a of the accelerator pedal 5 because the height T is about 1.5 cm long. In order to maintain the contacted state, it is necessary to position the heel part Kt of the operating foot about 1.2 cm (= sin 52 ° × 1.5 cm) below the heel part Km of the average height person M. Yes (see phantom line in FIG. 16). However, as shown by the solid line in FIG. 16, the tall person T operates the tall person T by changing the sole inclination angle θ7 of the tall person T from the appropriate angle (52 °) by about 4 ° to about 48 °. With the heel part Kt of the foot placed on the substantially horizontal floor mat surface 21 located behind the first inclined surface part 12, the lever ball part Bt abuts on the stepping point 5a of the accelerator pedal 5. It is possible to make it.

  Further, the ankle angle θ1 of the operating foot tends to be larger than 90 ° corresponding to the change in the inclination angle θ7 of the sole from 52 ° to 48 °. Correspondingly, by making the knee angle θ2 smaller than 120 ° and bending the knee, it is possible to prevent the ankle angle θ1 from increasing beyond an appropriate range, for example, 95 ° or more. it can. Furthermore, if the lever ball portion Bt of the operating foot is positioned slightly above the stepping point 5a of the accelerator pedal 5, there is an advantage that the change in the ankle angle θ1 can be more effectively suppressed.

  Next, a reference length in which the height of the driver sitting on the driver's seat 1 is set to about 4.5 cm by dividing the front end position Hs and the rear end position Ht of the recommended line P into, for example, eight equal parts. After obtaining the front and rear positions of the driver's seat 1 when sequentially increasing in units of height, the eyepoint (viewpoint height) is maintained while each driver having a predetermined height maintains a comfortable seating posture. The front / rear position, the vertical height, and the inclination of the seat cushion 1a that can be matched with the appropriate line L and can make the optimum position (the palm ball portion) of the sole contact the stepping point of the operation pedal. The angle is obtained based on the human body model and the design data of the driving posture adjustment device, and the hip points of each driver corresponding to this value are plotted on the graph shown in FIG. By connection, setting the basic control characteristic P.

  The seat front / rear position adjustment mechanism 2 that adjusts the front / rear position of the driver seat 1 as described above, the seat surface adjustment mechanism 3 that adjusts at least the vertical position of the seat surface of the driver seat 1, and the driver seat 1 are seated. When adjusting the front / rear position of the driver's seat 1 in a vehicle having an operation pedal including an accelerator pedal 5 or the like that is depressed by a driver, the seat adjustment mechanism 3 is operated in conjunction with the adjustment. Thus, since the main control means 85 is provided for controlling the vertical position of the seat of the driver seat 1 to be raised and lowered based on the preset basic control characteristic P, the user seated on the driver seat 1. There is an advantage that the driving posture of the driver can be adjusted easily and appropriately.

  In other words, when the driver's height changes, the driver's seat height, foot length, and the like change in proportion to this, so that the driver's steering wheel 20 seated on the driver's seat 1 and the operation pedal Because the operability and the height of the eye point I change, the steering wheel 20 can be properly operated while the driver seated on the driver seat 1 is seated in an easy posture, and the operation pedal is The seat front / rear position adjusting mechanism 2 is actuated so that the front / rear position of the driver seat 1 is adjusted.

  By operating the seat surface adjustment mechanism 3 in conjunction with an operation for adjusting the front / rear position of the driver seat 1, the seat surface of the driver seat 1 is moved up and down based on a preset basic control characteristic P. By executing the control for adjusting the vertical position in the main control means 85, the majority of drivers seated on the driver's seat 1 maintain the comfortable posture and operate the steering wheel operability. In addition, it has been confirmed by experiments conducted by the inventors that it is possible to effectively perform the operations of ensuring the front view properly by matching the eye point I with the appropriate line L while maintaining pedal operability. Yes.

  In particular, in the above-described embodiment, when the driver seat 1 is automatically moved back and forth according to the driver's switch operation by the seat adjustment mechanism including the seat front / rear position adjustment mechanism 2 and the seat surface adjustment mechanism 3. The seat surface of the driver's seat 1 is moved up and down in conjunction with the vehicle seat, and the vertical position thereof is adjusted, and the inclination angle of the seat cushion 1a and the inclination angle of the seat back 1b are changed at the same time. The operation of making the eye point I coincide with the appropriate line L corresponding to the seat height of the driver seated on the driver's seat 1 while suppressing an increase in the forward / backward movement distance of 1 and the raising / lowering distance of the seat surface. And it can be done properly.

  For example, a driver sitting on the driver's seat 1 changes from a tall person T to a short person S, and the driver's seat 1 is moved back and forth due to the low seat height of the short person S. When the operation of raising the seat surface of the seat 1 is performed, the inclination angle of the seat cushion 1a and the seat back 1b is changed in the direction in which the upper body of the short stature S is raised in conjunction with the operation. It is possible to effectively match the eye point Is of the short stature with the appropriate line L inclined downward. As a result, there is an advantage that the driving posture can be adjusted quickly and appropriately so as to ensure the driver's field of view without largely moving the driver seat 1 and its seating surface.

  A very small part of the driver seated on the driver seat 1 positions the eye point I above or below the appropriate line L in accordance with long-time driving style, physical characteristics, etc. May want. For example, a driver who prefers sports driving performs an operation of moving the front and rear positions of the driver's seat 1 and its seating surface up and down based on the basic control characteristics P in order to ensure the handle operability and pedal operability. After doing so, it may be desired to place the eye point I below the appropriate line L to avoid a feeling of hip height. On the contrary, it is desired to position the eye point I above the appropriate line L after performing an operation based on the basic control characteristic P with the intention of improving the visibility of the front lower part of the vehicle body. There is also a driver.

  In the driving posture adjusting apparatus according to the present invention, after the control operation by the main control means 85 is finished, the seat adjustment mechanism 3 is operated in accordance with the operation of the vertical position adjusting switch 82 by the driver, so that the driver seat. The seat surface of the driver's seat 1 is moved rearward by raising and lowering the seat surface of 1 and positioning it above or below the basic control characteristic P and operating the seat front-rear position adjusting mechanism 2 in conjunction therewith. Alternatively, since the sub-control means 86 that finely adjusts to move forward is provided, the eyepoint I is appropriately adjusted while maintaining the comfort posture of the driver seated on the driver's seat 1 and the handle operability and pedal operability. There is an advantage that an operation of positioning above or below the line L can be executed.

  For example, the driver seated on the driver's seat 1 operates the seat position adjustment mechanism 3 by operating the vertical position adjustment switch 82 with the intention of positioning the eye point I above the appropriate line L. When a fine adjustment operation for moving the hip point H of the driver above the vertical position set based on the basic control characteristic P and moving the eye point I above the appropriate line L is performed. The control of moving the seat surface (hip point H) of the driver's seat 1 diagonally rearward along a preset first reference line by operating the seat front / rear position adjusting mechanism 2 in conjunction with this. The sub-control means 86 is configured to execute.

  Further, the driver seated on the driver seat 1 operates the vertical adjustment switch 82 to operate the seat adjustment mechanism 3 with the intention of positioning the eye point I below the appropriate line L. When the fine adjustment operation for moving the hip point H of the driver below the vertical position set based on the basic control characteristic P and moving the eye point I below the appropriate line L is performed. In conjunction with this, the seat front / rear position adjusting mechanism 2 is operated to move the seat surface (hip point H) of the driver's seat 1 diagonally forward along a preset first reference line. The sub-control means 86 executes this.

  In this embodiment, as shown in FIG. 18 and FIG. 19, the seat surface of the driver's seat 1 is specifically defined with the first reference line Q as a fulcrum at the driver's knee N seated on the driver's seat 1. Is set in a direction in which the hip point H of the occupant seated on the driver's seat 1 is oscillated and displaced. Then, according to the operation of the vertical position adjustment switch 82 by the driver, the seat surface of the driver's seat 1 is oscillated and displaced with the knee portion N of the driver as a fulcrum to adjust the vertical position. Control for operating both the surface adjustment mechanism 3 and the seat front-rear position adjustment mechanism 2 at a predetermined ratio is executed by the sub-control means 86.

  That is, when it is configured to raise and lower the hip point H of the driver seated on the driver seat 1 by operating only the seat surface adjustment mechanism 3 in accordance with the operation of the vertical position adjustment switch 82, Corresponding to the swinging direction of the front link 53 and the rear link 55 of the seat surface adjusting mechanism 3, as shown by the broken line Q1 in FIGS. When the hip point H is lowered, the hip point H moves obliquely backward. When the hip point H moves in this direction, the driver's knee N seated on the driver's seat 1 also moves in an oblique direction as shown by a broken line Q1 in FIG. In addition, since the sole angle θ7 varies significantly, it is inevitable that the operability with respect to the operation pedal including the accelerator pedal 5 and the like deteriorates.

  On the other hand, by operating both the seat surface adjustment mechanism 3 and the seat front / rear position adjustment mechanism 2 in accordance with the operation of the vertical position adjustment switch 82 by the driver as described above, as indicated by a broken line Q1 in FIG. Next, the seat surface of the driver's seat 1 is raised and lowered to position the hip point H above or below the basic control characteristic P, and in conjunction with this, as shown by a virtual line Q2 in FIG. When the sub-control means 86 is configured to perform fine adjustment to move the seat surface of the seat 1 backward or forward, the knee portion N of the driver seated on the driver seat 1 moves. The hip point H is moved above or below the position corresponding to the basic control characteristic P while the eye point I is moved along the appropriate line L. As is located in a square or lower is advantageous in that it can be finely adjusted.

  In particular, as shown in the above-described embodiment, the seat surface of the driver seat 1, specifically the hip point H of the passenger seated on the driver seat 1, with the knee N of the driver seated on the driver seat 1 as a fulcrum. When both the seat surface adjustment mechanism 3 and the seat front / rear position adjustment mechanism 2 are configured to operate at a predetermined ratio based on the first reference line Q set in the direction of swinging displacement, The driver's eye point I can be moved above or below the appropriate line L as desired without moving the knee portion N of the driver seated on the driver seat 1 at all. Accordingly, by accurately maintaining the driver's ankle angle θ1 and sole angle θ7 set to appropriate values according to the control operation by the main control means 85, the operability of the operation pedal including the accelerator pedal 5 and the like can be improved. There is an advantage that it can be maintained in a good state.

  As shown in the above embodiment, the hip point H is based on the basic control characteristic P as shown by the solid line Q in FIG. 19 without moving the knee N of the driver sitting on the driver seat 1. When the operation of moving above or below the set position is performed, the knee angle θ2 and the elbow angle θ5 of the driver seated on the driver seat 1 change in response to this operation. The knee angle θ2 and the elbow angle θ5 have a greater degree of freedom than the ankle angle θ1 and the sole angle θ7, and even if the knee angle θ2 and the elbow angle θ5 slightly change, the driver's comfort posture is impaired. There is a low possibility that adverse effects such as damage to pedal operability will occur.

  However, when the driver feels uncomfortable due to changes in the knee angle θ2 and the elbow angle θ5, the seat front / rear position adjustment mechanism 2 is operated by operating the front / rear position adjustment switch 83. In addition to moving the seat surface of the driver's seat 1 back and forth, and operating the seat surface adjustment mechanism 3 in conjunction with this, the control to move in the oblique direction along the preset second reference line is performed as described above. If it is executed by the sub-control means 86, it is possible to eliminate the uncomfortable feeling.

  As shown in FIG. 20 and FIG. 21, the second reference line R is a direction inclined forward and downward at an angle of about 8 °, that is, an appropriate line L of the eye point I of the driver seated on the driver's seat 1. It is set in parallel. Then, according to the operation of the front / rear position adjustment switch 83 by the driver, the front / rear position is adjusted by moving the seat surface (hip point H) of the driver's seat 1 parallel to the appropriate line L of the eye point I. In addition, the sub-control means 86 is configured to execute control for operating both the seat front / rear position adjusting mechanism 2 and the seat surface adjusting mechanism 3 at a predetermined ratio.

  That is, when the hip point Hm of the average height person M seated on the driver's seat 1 is moved back and forth by operating only the seat front / rear position adjustment mechanism 2 according to the operation of the front / rear position adjustment switch 83. When the hip point H is moved forward in accordance with the inclination angle of the seat slide lower rail 41, the hip point H moves obliquely upward as indicated by a broken line R1 in FIG. Further, when the hip point H is moved backward, the hip point moves obliquely downward along the broken line R1. When the hip point H moves as described above, the driver's eye point I seated on the driver's seat 1 is also displaced in the above direction as indicated by a broken line R1 in FIG. The height of the eye point I positioned above or below the appropriate line L in accordance with the operation of the adjustment switch 82 inevitably deviates from the desired position.

  On the other hand, by operating both the seat front / rear position adjustment mechanism 2 and the seat surface adjustment mechanism 3 in accordance with the operation of the front / rear position adjustment switch 83 by the driver as described above, the broken line R1 in FIG. Further, the control for finely adjusting the seat surface of the driver's seat 1 to move back and forth, and moving the seat surface of the driver's seat 1 upward or downward as shown by an imaginary line R2 in conjunction with this is described above. When configured to be executed by the sub-control means 86, as shown in FIG. 21, the seat surface (hip point H) of the driver's seat 1 is suppressed while suppressing the vertical displacement of the driver's eye point I. By moving back and forth, there is an advantage that it is possible to effectively eliminate the uncomfortable feeling caused by the driver's knee angle θ2 changing greatly.

  In particular, as shown in the above embodiment, along the second reference line R set in parallel with the appropriate line L of the eye point I, the seat surface of the driver seat 1, specifically, the driver seat 1. When the seat front / rear position adjustment mechanism 2 and the seat surface adjustment mechanism 3 are both operated at a predetermined ratio in the direction in which the hip point H of the seated occupant is moved, the solid line R in FIG. As shown, the seat surface of the driver's seat 1 can be moved back and forth as desired without changing the relationship between the driver's eye point I and the appropriate line L at all. Therefore, the seat of the driver seat 1 is accurately maintained while maintaining the height of the eye point I positioned above or below the appropriate line L according to the operation of the vertical position adjustment switch 82 at a desired position. By moving the surface back and forth, there is an advantage that the uncomfortable feeling caused by the change in the knee angle θ2 and the like can be surely eliminated.

  Further, for example, a driver having a physical feature that the limb is long but the seat height is low as compared with an average human body model or the like can change the front-rear position of the driver seat 1 according to the handle operability and the pedal operability. Even when a situation occurs in which the eye point I is located below the appropriate line L when set, or in the opposite situation, after the control operation by the main control means 85 ends. The seat surface adjustment mechanism 3 is operated to raise and lower the seat surface of the driver's seat 1, and the seat front / rear position adjustment mechanism 2 is operated in conjunction with this to move the seat surface of the driver seat 1 backward or forward By making the fine adjustment to be moved to the sub-control means 86, the driver's eye point I is made to coincide with the appropriate line L, so that the front view can be properly secured. There is a point.

  The sub-control means 86 performs control for operating the seat back switch 84 to adjust the tilt angle by tilting and displacing the seat back 1b of the driver's seat 1 as necessary. There is an advantage that the seating posture can be adjusted more appropriately according to the preference.

  Further, in the above embodiment, in the driving posture adjusting device in which the operation pedal including the brake pedal 4 and the accelerator pedal 5 that are depressed by the operating feet of the driver sitting on the driver's seat 1 is disposed in the front part of the passenger compartment. The driver's seat floor mat 11 is laid on the vehicle body floor portion 8 located at the feet of the driver seated on the driver's seat 1, and the upper surfaces 15, 16 are lifted forward on the driver seat floor mat 11. By providing the inclined first and second inclined surface portions 12 and 13, a bulging portion whose thickness increases toward the front is formed, and the bulging portion including the first and second inclined surface portions 12 and 13 is formed. Since it is disposed in the heel-mounting area of the operation foot located behind the operation pedal, the driving posture can be maintained with a simple configuration so that the driver sitting on the driver's seat 1 can operate the operation pedal properly. And it can be appropriately adjusted.

  For example, as shown in FIG. 4 and the like, the first inclined surface portion 12 is provided behind the brake pedal 4, the second inclined surface portion 13 is provided behind the accelerator pedal 5, and front and rear of the first inclined surface portion 12. When the dimension is set to be shorter than the front and rear dimension of the second inclined surface portion 13, the driver seats on the driver seat 1 without adversely affecting the pedal switching operation by the tall person T sitting on the driver seat 1. The short stature person S, with the heel part Ks of the operating foot placed on the second inclined surface part 13 as shown by the phantom line in FIG. By abutting on 5a, there is an advantage that the stepping operation can be appropriately performed.

  That is, three subjects having a height of 150 cm, six subjects having a height of 160 cm, and three subjects having a height of 170 cm, each having a normal heel placement position in plan view. As a result, the data as shown in FIG. 22 was obtained. From this data, in the subject having a height of 150 cm, the normal saddle placement position is concentrated on the rear side of the accelerator pedal 5 and relatively in front of the accelerator pedal 5, and in the subject having a height of 170 cm. In the case of a subject having a normal heel mounting position concentrated on the rear side between the brake pedal 4 and the accelerator pedal 5 and relatively rearward, and having a height of 160 cm, It can be seen that the positions are dispersed over a wide range.

  This is because, as shown in FIG. 23, the short stature person S with a short sole dimension moves from the operating state of the accelerator pedal 5 to the operating state of the brake pedal 4 if the mounting position of the buttock Ks is not moved greatly. This is because, since the pedal cannot be changed, a normal saddle placement position is often set on the rear side of the accelerator pedal 5 so that the accelerator pedal 5 can be easily operated in normal times. On the other hand, as shown in FIG. 24, the tall person T having a long sole size shifts from the operating state of the accelerator pedal 5 to the operating state of the brake pedal 4 without greatly moving the mounting position of the buttocks Kt. Since it is possible to perform the pedal change operation, the normal operation is performed on the rear side between the brake pedal 4 and the accelerator pedal 5 with the intention of enabling the change operation. This is considered to be for setting the saddle placement position.

  Therefore, as shown in the above-described embodiment, the second inclined surface portion 13 having a larger front-rear dimension than the first inclined surface portion 12 is formed in a portion located rearward of the stepping point 5a of the accelerator pedal 5 in plan view. Therefore, when the upper surface 16 is inclined forward and upward toward the stepping point 5a of the accelerator pedal 5, the short stature S having a short sole dimension compared to the tall stature T or the like While the ankle angle K1 and the inclination angle θ7 of the sole are maintained at appropriate angles in a state where the heel portion Ks of the heel portion is placed on the second inclined surface portion 13, the stepping point of the accelerator pedal 5 is set to the lever ball portion Bs. 5a. For this reason, subtle pedal operation becomes impossible due to the fact that the short stature S performs the depression operation of the accelerator pedal 5 with the buttocks Ks of the operation foot separated from the floor surface, and the ankle angle The advantage that the accelerator pedal 5 can be easily and appropriately depressed without making it difficult to quickly depress the accelerator pedal 5 due to the large deviation of θ1 and the inclination angle θ7 of the sole from the appropriate angle. There is.

  When the short stature S operates the brake pedal 4 slowly, the ankle angle θ1 and the inclination angle of the sole are moved by moving the heel portion Ks of the operation foot onto the first inclined surface portion 12. There is an advantage that the lever ball portion Bs of the operating foot can be brought into contact with the stepping point 4a of the brake pedal 4 and can be appropriately operated while maintaining θ7 at a substantially appropriate angle. And since the front-back dimension of the said 1st inclined surface part 12 is set short compared with the 2nd inclined surface part 13 formed in the back of the said accelerator pedal, when the short stature S operates the brake pedal 4 suddenly Effectively prevents the heel portion Ks of the operating foot from interfering with the rear end of the first inclined surface portion 12 while making the lever ball portion Bs abut against the stepping point of the brake pedal 4 for rapid braking. The operation can be performed.

  On the other hand, in the case of a tall person T, as shown in FIGS. 15 and 16, if the sole inclination angle θ7 of the operating foot is decreased and the knee angle θ2 is decreased, the buttocks Kt is moved downward. Without this, the lever ball portion Bt of the operating foot can be easily and properly brought into contact with the stepping point 5a of the accelerator pedal 5. Therefore, by setting the front and rear dimensions of the first inclined surface portion 12 located behind the brake pedal 4 to be shorter than the second inclined surface portion 13 located behind the accelerator pedal 5, the tall person T can operate the operating foot. The accelerator pedal 5 is stepped on even if the heel mounting area for mounting the heel portion Kt is set on the substantially horizontal floor mat surface 21 (non-bulged portion) located behind the second inclined surface portion 13. The operability is not adversely affected. In addition, the heel placement area on which the tall person T places the heel portion of the operation foot is configured by the substantially horizontal vehicle body floor portion 8, so that the heel portion Kt of the operation foot is placed on the tall person T. The power position can be easily recognized.

  Further, in the case of a tall person T, the rear side portion between the brake pedal 4 and the accelerator pedal 5, that is, the rear side of the rear end portion of the first inclined surface portion 12 and the second inclined surface portion 13. Since the accelerator pedal 5 and the brake pedal 4 can be switched with the buttocks Kt of the operating foot positioned on the side portions, the pedal switching operation is the first and second pedal operations. There is an advantage that the occurrence of the situation of being obstructed by the inclined surface portions 12 and 13 can be effectively prevented.

  Moreover, in the said embodiment, inclination-angle (alpha) with respect to the horizontal surface of the inclined surface which consists of the upper surface 15 of the 1st inclined surface part 12 located in the back of the brake pedal 4 is made into the 2nd inclined surface part 13 located in the back of the said accelerator pedal 5. Since the inclination angle β of the inclined surface formed by the upper surface 16 is set to be larger, the front-rear dimension can be effectively shortened while maintaining the height of the first inclined surface portion 12. Therefore, a stepping operation on the accelerator pedal 5 or the brake pedal 4 by a tall person who may place the buttocks of the operating foot at a position close to the rear end portion of the first inclined surface portion 12 is performed by the first pedal. There is an advantage that it is possible to prevent a situation in which the inclined surface portion 12 is obstructed due to the presence of the inclined surface portion 12. Moreover, when the short person S operates the brake pedal 4 as described above, the heel part Ks of the operating foot is placed on the bulging part of the driver's seat floor mat 11 formed of the first inclined surface part 12.
