Vehicle driving posture adjusting device

Abstract

A driving position adjusting device comprises a seat-position adjusting mechanism to adjust height and seat-face angle of a seat cushion in accordance with longitudinal movement of a driver's seat, and a floor adjusting mechanism to adjust a height of a floor board in accordance with the operation of the longitudinal adjustment of the driver's seat, wherein the seat-position adjusting mechanism is configured so that an inclination angle of the seat cushion becomes smaller as the driver's seat is moved forward from a middle position, and the floor adjusting mechanism is configured so that the height of the floor board becomes higher as the driver's seat is moved forward from the middle position. Accordingly, the sitting position of the driver and the operational function of the operational pedal can be provided properly regardless of the body size of the driver.

Description

technical field [0001] The present invention relates to a driving posture adjustment device for appropriately adjusting the driving posture of a driver seated in a driver's seat. Background technique [0002] Conventionally, for example, Japanese Patent Laid-Open Publication No. 2006-44422 (hereinafter referred to as "Patent Document 1") discloses a driving posture adjustment device for adjusting the driving posture of a driver seated in the driver's seat. In the device, there is a physique detection device for detecting the physique of the driver; a foot pedal composed of a brake pedal for the above-mentioned driver to step on; a movable floor part that can be raised and lowered provided near the foot pedal The floor adjustment device for adjusting the lifting position of the movable floor part, through the floor adjustment device, corresponding to the driver's physique measured by the above-mentioned physique detection device, the smaller the physique, the more the above-m...

Problems solved by technology

However, if the front-rear position, the up-and-down position, and the inclination angle of the seat cushion are respectively changed according to the physique of the driver as described above, the sitting posture of the driver will change significantly accordingly, so it is difficult to adapt the seat cushion accordingly. If the lifting displacement of the above-mentioned movable floor part is set incorrectly, the driver's sitting posture becomes unstable, or the operability of the pedals etc. deteriorates.

[0004] That is, when replacing the driver seated in the above-mentioned driver's seat, the driver who is seated later moves the driver's seat forward and backward through the seat position adjustment mechanism, so that the height of the viewpoint is consistent with the reasonable line of sight to ensure the front view. The up and down position and inclination angle of the driver's seat change simultaneously with the forward and backward movement of the driver's seat. Therefore, the driver's sitting posture relative to the driver's seat, specifically, the erection angle of the upper body relative to the horizontal line and the height of the thighs and knees The bending angle of the upper part, that is, the knee angle, etc. will change, and correspondingly, the operability of the above-mentioned pedals will also change.

Therefore, even if the above-mentioned movable floor portion is raised and lowered only by focusing on the difference in the size of the feet corresponding to the change in the physique of the driver, it is difficult to properly balance the driver's sitting posture and the operability to the pedals.
