DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a footrest used by a driver or the like in a vehicle to put his / her feet on.

[0002]

2. Description of the Related Art In a conventional vehicle, as shown in FIG. 3, a toe board 1 is composed of a vertical wall surface 4 separating an engine room 2 and a vehicle room 3 and an inclined portion 5 therebelow. With the footrest 6 fixed, the driver 8 sitting in the driver's seat 7 puts his sole on the footrest 6 and
It is common to put the heel on the floor 9 in the passenger compartment 3,
In this case, when the toeboard 1 moves rearward during the collision of the vehicle, as shown in FIG. 4, the inclination of the tread surface of the footrest 6 changes, and the toe of the driver 8 is pushed rearward, while the heel of the driver 8 is raised. As a result of being fixed on the floor 9, a bending moment centered on the ankle acts on the toe of the driver 8 as shown by the arrow, and the toe is bent backward, so that the bending at the ankle is performed. When the corner reaches that limit, a large bending moment may be generated at the shin of the driver 8.

In the footrest described in Japanese Utility Model Laid-Open Publication No. 4-59532, the entire foot of the driver is placed on the upper surface of the footrest. Since both are fixed to the vehicle body side, if the toeboard moves rearward during a vehicle collision, the rearward inclination of the upper surface of the footrest will also increase,
A bending moment centered on the ankle acts on the driver's toe, and the same problem as described above is concerned.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to apply a large bending moment to the shin of an occupant due to displacement of the footrest during a vehicle collision, even if the occupant's toe of the vehicle is placed on the footrest. Is to suppress.

[0005]

Therefore, a footrest of a vehicle according to the present invention is formed so as to be connected to an upper portion having an inclined surface on which a sole of a vehicle occupant is placed, and to be connected to a lower end of the inclined surface. Has a lower portion having a tread surface on which the heel of the vehicle is mounted, the upper portion is fixed to the passenger compartment side of a vertical wall surface of a toeboard that separates an engine room and a passenger compartment of the vehicle, and the lower portion is restrained in the front-rear direction of the vehicle It is located on the vehicle floor without.

That is, since the lower portion of the footrest having the tread on which the heel of the occupant is placed is disposed on the vehicle floor without being restrained in the front-rear direction of the vehicle, the vertical wall surface of the toeboard moves rearward in the event of a vehicle collision. If the upper part of the footrest fixed to the cabin side of the toe board vertical wall displaces rearward due to the above movement, the lower part of the footrest will also be displaced in the same way, but the sole of the occupant will be inclined at the upper part of the footrest. At the same time, the heel of the occupant is placed on the tread below the footrest, so that the occupant's toe is urged backwards in a constant state, and the toe is The application of a bending force centering on the ankle is restricted, so that the generation of a large bending moment on the shin of the occupant can be reliably suppressed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described by assigning the same reference numerals to the same parts as those of the conventional device. In FIG. 1, a toe board 1 of a vehicle includes a vertical wall surface 4 separating an engine room 2 and a vehicle compartment 3 and an inclined portion 5 therebelow. A floor 9 in the vehicle compartment 3 is connected to a lower end of the inclined portion 5. .

The footrest 10 comprises an upper part 11 and a lower part 12 extending rearward from the lower end of the upper part 11. The upper part 11 of the footrest is bolted to the toe board vertical wall surface 4, and the sole of the occupant's foot 14. On the upper surface of the lower portion of the footrest 12, there is formed a tread surface 16 on which the heel of the occupant's toe 14 is placed, and the back surface of the inclined surface 15 in the upper footrest 11 and the lower surface of the lower portion 12 of the footrest. Are simply placed on the toeboard slope 5 and the floor 9, respectively, none of which is restrained in the vehicle longitudinal direction.

In the above-mentioned apparatus, as shown in FIG. 2, when the toeboard vertical wall surface 4 moves rearward due to the collision of the vehicle and the toeboard inclined portion 5 and a part of the floor 9 are deformed accordingly, the upper end portion is moved. The footrest 10 whose bolt 13 is bolted to the toeboard vertical wall surface 4 moves rearward together with the toeboard vertical wall surface 4. In this case, the upper part 11 and the lower part 12 are displaced integrally rearward, and the inclined surface 1 of the upper part 11 is moved.
The relative angle between 5 and the tread 16 of the lower part 12 is kept constant.

Therefore, the relative condition of the sole and heel of the occupant's toe 14 placed on the inclined surface 15 and the tread surface 16 can be prevented from being noticeably changed, and the bending angle of the toe 14 around the ankle can be avoided. Can easily be kept within an allowable range, so that a large bending moment centered on the ankle acts on the toe 14 as in the conventional device, and generates a large bending moment on the shin of the occupant. In this respect, the occupant's legs can be protected from a vehicle collision.

In the above embodiment, the upper portion of the footrest is placed on the toeboard inclined portion, and the lower portion of the footrest is placed on the passenger compartment floor. Even if the upper end of the footrest is fixed to the toeboard vertical wall surface so as to provide a vertical gap between the lower surface of the toeboard and the lower part of the footrest and the cabin floor, respectively, It goes without saying that the same operation and effect as the above embodiment can be obtained.

[0012]

In the vehicle footrest according to the present invention, the lower part of the footrest having the tread on which the heel of the occupant is placed is disposed on the vehicle floor without being restrained in the longitudinal direction of the vehicle. Even if the vertical wall surface of the toeboard moves rearward and the footrest displaces rearward in the event of a vehicle collision, the occupant's toe placed on the footrest is urged rearward as a whole in a fixed state and bent to its ankle. Is restricted, the generation of a large bending moment in the shin of the occupant can be reliably suppressed, and the leg of the occupant can be protected.
