[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a passenger compartment of an automobile, and more particularly to a floor structure of a front seat of a passenger compartment.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a passenger compartment floor 1 at the foot of a passenger seat such as a semi-bonnet type wagon vehicle is
A vertical wall-shaped dash portion 2 that separates the engine room from the vehicle compartment is erected in the front, and is separated from the floor on the driver's side by a center lower portion 60 of an instrument panel 6 provided in the central portion in the vehicle width direction. Has been. In addition, a wheel house 4 that bulges toward the vehicle compartment side in an arch shape is formed along the lower end of the cowl side portion 3 that is a side wall of the front portion of the vehicle body on the floor 1 near the passenger seat. Further, the bent portion between the front end of the floor 1 and the lower end of the dash portion 2 forms a toeboard portion 5 having a front rising slope between the wheel house 4 and the center lower portion 60. The floor 1, the wheel house 4, and the toe board portion 5 are covered with a floor carpet having a felt material joined to the back surface thereof, and the dash portion 2 is covered with a dash silencer which is a sound absorbing material.

[0003]

By the way, in the conventional floor structure of the front passenger's seat, when the passenger sitting in the passenger's seat extends his or her legs, the right foot of the passenger can be placed on the toe board portion 5, but the left foot is the wheel. It hits the house 4 and the foot placement is not good. If the left foot is also placed on the toe board section 5 while avoiding the wheel house 4,
The width is narrow and cramped because the wheel house 4 is overhanging.

Further, as shown in FIG. 5, the toe board section 5
Has a short front-back length L ₀ of about 200 mm, and when you put your foot on it, the toes rest on the toe board 5, but the heel contacts the floor 1 and the middle between the toes and the heel floats. The foot placement property on the part 5 is also insufficient. Toe board section 5
Since the lower end of the dash panel of the dash portion 2 is bent and inclined, the toe board portion 5 is erected and deformed to the passenger compartment side at the time of a frontal collision of the vehicle, and the angle formed by the occupant's foot and the shin portion is It may decrease and damage the shin.

Therefore, the present invention eliminates the step of the wheel house, expands the toe board surface to improve the foot placement of the occupant, and reduces the damage to the shin of the occupant during a frontal collision of the vehicle. The challenge was to realize a floor structure that is close to the seats.

[0006]

DISCLOSURE OF THE INVENTION The present invention is a vehicle compartment floor near the front seats of an automobile, in which a dash portion for partitioning the vehicle compartment and the engine room is provided in the front, and the vehicle interior is arched in the front side. In an automobile floor structure in which a wheel house that bulges into is formed, a pad member that forms a flat inclined surface that rises forward from the passenger compartment floor to the dash portion is installed at the front of the passenger compartment floor. The pad member covers the wheel house, and a flat toe board surface is formed by the inclined surface of the pad member (claim 1). Since the step difference in the wheel house can be eliminated and the front-rear length of the toe board surface can be set to be long, it is possible to improve the foot placement of the occupant. Further, even if the dash portion is displaced rearward in the event of a vehicle collision, the pad member prevents the angle formed between the occupant's foot and the shin portion from decreasing and prevents the occupant from damaging the shin portion.

The pad member is a shock-absorbing pad made of synthetic resin, and has a substantially triangular cross section including a bottom surface along the passenger compartment floor, a vertical surface along the dash portion, and the inclined surface forming the upper surface, and side ends. A notch is formed which substantially coincides with the wheel house (claim 2). The pad member has a good sense of stability, and the foot placement of the occupant is further improved.

The inclined surface of the pad member is covered with a floor carpet (claim 3). Does not impair the appearance of the passenger compartment floor.
