Description

  The present invention relates to a driving posture adjusting device for a vehicle that adjusts the posture of an occupant (driver) seated in a driver seat.

  In general, as shown in FIG. 28, in the conventional vehicle, the layout of the seat 100, the floor panel 101, and the accelerator pedal 102 (or brake pedal) on which the occupants L, M, and S are seated is a standard (medium) occupant M. Designed to suit.

  The seat 100 includes a seat cushion 103, a seat back 104, and a headrest 105. As shown in FIG. 29, a seat slide device (not shown) occupants L, M, The hip points P11, P12, and P13 of S are configured to move back and forth in a substantially horizontal direction, but the position of the accelerator pedal 102, the pedal operation angle, and the seating surface angle of the seat 100 are fixed.

  For this reason, there were the following problems. That is, the passengers L, M, and S operate the accelerator pedal 102 with a heel on the floor mat 107 laid on the top surface of the floor panel 101. In this case, the occupant L having a large physique and the occupant M having a standard physique can reach the accelerator pedal 102 sufficiently, but in the case of the occupant S having a small physique, the foot does not sufficiently reach the accelerator pedal 102. When the accelerator pedal 102 is operated with a heel on, the pedal 102 is stepped on at the toe portion, and when the accelerator pedal 102 is depressed, the accelerator pedal 102 moves forward in the vehicle front-rear direction. In order to eliminate such problems, the occupant S having a small physique sits at a position closer to the front of the seat cushion 103, and after lifting the heel from the floor mat 107 surface, the accelerator pedal 102 There was a problem that it was necessary to operate.

  In addition, because of the difference in the physique of the occupants L, M, and S seated on the seat 100, the opening angle angle between the upper and lower legs of the occupant is significantly different. Since the direction in which the tread surface of the pedal 102 is depressed and the angle of the tread surface are not compatible with a state in which the (below the ankle) is bent upward, the pedal operability is poor. Therefore, conventionally, the passengers L, M, and S themselves have adjusted their driving postures in order to appropriately ensure the operability of the accelerator pedal 102 and the brake pedal.

On the other hand, a vehicle driving posture adjusting apparatus as shown in FIG. 30 has already been invented (see Patent Document 1).
This conventional apparatus shown in FIG. 30 is configured to adjust the position of the seat 200 in the inclination direction between the front upper part and the rear lower part, and adjust the front and rear positions of the brake and / or accelerator pedal 201 in a substantially horizontal direction. In addition, the positional relationship between the pedal 201 and the seat 200 is configured to be maintained substantially constant according to the occupant's physique.

  The conventional apparatus shown in FIG. 30 has an advantage that the foot of an occupant having a small physique can reach the pedal 201 sufficiently, but has the following problems.

  That is, the lower part of the human ankle (so-called foot) can move up and down with the ankle joint as a fulcrum, but does not bend upward beyond a certain level. When the occupant operates the pedal 201, the pedal 201 is operated by moving the foot downward from a state where the foot is bent upward with the ankle joint as a fulcrum. In this case, since the angle of the tread surface of the pedal 201 and the angle of the seating surface of the seat 200 are constant, when the occupant operates the pedal 201, the foot is raised with the angle of the tread surface of the pedal 201 and the occupant's ankle joint as a fulcrum. The direction of depressing the pedal tread from the bent state becomes incompatible and there is a problem that the operability of the pedal is bad, and it is difficult to optimize the leg angle and pedal operation direction of the occupant operating the pedal Met.
