Description of the Related Art A seat provided in a vehicle compartment forming portion of a vehicle is designed to be capable of maintaining a proper driving posture of a seated occupant, especially when the seat is intended for a driver. desired. The proper driving posture for the occupant seated on the driver's seat is such that the occupant's eye point is the front view of the vehicle, the rear view of the vehicle obtained through the rearview mirror, and the left and right fender mirrors or door mirrors. The vehicle's left and right sides of the vehicle can be easily and surely obtained by driving the steering wheel and the steering column , Operation of various operation parts arranged on the dashboard, console, etc., operation of shift lever, operation of hand brake, operation of operation pedals such as accelerator pedal, brake pedal, clutch pedal, etc., easily and It is a posture that allows smooth operation, especially for accelerator pedals, brake pedals, clutch pedals, etc. It can be performed the operation of the operation pedal to reasonably ensure it is important.

The driver's seat is usually supported via a slide mechanism including rails extending and fixed in the front-rear direction of the vehicle on a floor portion of a vehicle compartment forming portion of the vehicle, and an operation provided for the slide mechanism is provided. By operating an operating member such as a lever, the slide mechanism is moved in the front-rear direction, whereby the arrangement position can be adjusted. Therefore, the occupant seated on the driver's seat can adjust the position of the driver's seat mainly so that the operator can operate the operation pedal without difficulty according to his / her body size. . However, even in the driver's seat in which the arrangement position of the vehicle in the front-rear direction can be adjusted, the adjustment range is naturally limited to a certain range due to the positional relationship with each part in the vehicle interior forming part. Therefore, the arrangement position of the driver's seat and its adjustment range are usually set by assuming an occupant having an average physique and a physique relatively close to it. Therefore, if the occupant sitting on the driver's seat has an average physique or a physique that is not relatively close to the average physique, the position of the driver's seat is adjusted so that the proper eye point position is obtained. There is a possibility that it may be difficult to take the desired desired driving posture.

In order to alleviate some of the inconvenience associated with the driver's seat in which the arrangement position of the vehicle in the front-rear direction can be adjusted, not only the arrangement position in the front-rear direction but also the up-down direction of the vehicle can be adjusted. There is also known a driver's seat in which the arrangement position adjustment is also possible. According to the driver seat capable of adjusting the arrangement position in each of the front-back direction and the vertical direction, the possibility of the arrangement position adjustment in which the occupant seated on the seat can place the eye point at an appropriate position is expanded. However, from the viewpoint of whether or not the driver can take a driving posture in which the operation pedals such as the accelerator pedal, the brake pedal, and the clutch pedal can be operated reasonably and reliably,

According to the above, a vehicle equipped with a vehicle that can be moved in the front-rear direction and the up-down direction and whose arrangement position can be adjusted has been proposed.
In a vehicle equipped with such an operation pedal capable of adjusting the arrangement position, the occupant seated on the driver's seat is
This makes it possible to cause the operation pedal to assume an arrangement position where it is easy to perform the operation within a predetermined adjustment range without changing the position of the eye point.

[0006]

However, as described above, the driver's seat in the vehicle and the operation pedals arranged in front of the driver's seat are separately provided in the front-rear direction and the up-down direction of the vehicle. In the case where the occupants seated on the driver's seat can obtain the proper eye point position and the operation pedal When performing the posture adjustment for taking the desired driving posture that allows the operation of the above, the first step is to adjust the position of the driver's seat in the front-back direction and the vertical direction, and then It is necessary to adjust the arrangement position of the operation pedal in the front-back direction and the vertical direction. Therefore, for the occupant sitting on the driver's seat,
There is the inconvenience that complicated and troublesome adjustment work is required each time.

Further, when the arrangement position adjustment of the driver's seat or the operation pedal is performed in the vehicle, the movement of the arrangement position of the driver's seat or the operation pedal accompanying the adjustment of the arrangement position, in particular, the operation pedal. Since there is a possibility that the driving posture of the driver will be temporarily disturbed due to the movement of the arrangement position of the operation pedal accompanying the adjustment of the arrangement position of the driver seat and the operation pedal. It is necessary to consider the movement of the respective arrangement positions in order to be performed efficiently.

In view of such a point, the present invention provides a driver's seat arranged on a floor portion of a vehicle compartment forming portion of a vehicle, an accelerator pedal, a brake pedal, etc. arranged in front of the driver's seat. Take the desired driving posture that allows the operation pedals to be operated reasonably and reliably with an appropriate eye point position by the occupant sitting on the driver's seat, which is due to the arrangement position adjustment of each of the operation pedals. Except for exceptional cases, the posture adjustment for the operation is extremely easy without any troublesome and troublesome adjustment work for the occupant, regardless of the physical size of the occupant, and the operation accompanying the position adjustment It is an object of the present invention to provide a driving posture adjusting device for a vehicle, in which the respective positions of the passenger seat and the operation pedal are moved efficiently and accurately. To.
