Abstract

PROBLEM TO BE SOLVED: To provide a footrest of a low cost which is made possible to suppress the erection of the foot loading surface of the foot rest in a collision. SOLUTION: Weakened holes 42 are formed to the upper half part of the side plate 41 of a box form footrest made of a resin having a foot loading surface 40, and the buckling strength of the upper part area of the main body 4 is made weak. The upper part area of the main body 4 is smashed by the load in the colliding time, so as to suppress the erection of the foot loading surface 40. In this case, the shearing strength of the upper part area of the foot loading surface 40 may be made weak, so as to break the upper part area by the load in the colliding time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footrest for an automobile on which an occupant's foot rests.

[0002]

2. Description of the Related Art In general, a footrest is disposed on a toeboard surface which rises obliquely forward from a floor surface of a vehicle cabin in a forwardly inclined position.

[0003] By the way, in the event of a collision, the footrest may rise from an inclined posture due to the rearward deformation of the toeboard. When the footrest stands, the angle between the occupant's foot and the shin is reduced, and it is desired to suppress the standing of the footrest, particularly the standing of the footrest surface of the footrest during a collision.

Conventionally, Japanese Patent Application Laid-Open No. Hei 8
According to Japanese Patent No. -164782, in a cross-sectional shape viewed from the vehicle width direction, a first member made of a substantially triangular soft material having an upper end surface of a footrest as a base and a substantially triangular first member having a lower end surface of a footrest as a base. A footrest formed by bonding a second member made of a hard material to a second member is known.
In this case, the first member is compressed by the load at the time of the collision, and the compression allowance is increased on the upper side of the footrest, so that the standing surface of the footrest of the footrest is suppressed.

[0005]

In the above-mentioned prior art, the footrest is composed of two members, which increases the cost. In addition, the first member made of a soft material is elastically deformed even in a normal state, so that the footrest has a small size. There is a problem that stability is impaired.

In view of the above, it is an object of the present invention to provide a low-cost footrest capable of suppressing standing of a footrest surface at the time of a collision and ensuring stability during normal operation. I have.

[0007]

Means for Solving the Problems In order to solve the above problems,
According to the first aspect of the present invention, in a footrest for an automobile, which is disposed in a forwardly inclined position on a toeboard surface rising diagonally forward from a floor surface of a passenger compartment, a resin having a footrest surface for placing a foot of an occupant is provided. The buckling strength of the upper region of the molded footrest body is made weaker than that of the lower region.

According to a second feature of the present invention, there is provided an automobile footrest which is arranged in a forwardly inclined position on a toe board surface rising diagonally forward from a floor surface of a vehicle compartment.
The shear strength of the upper region of the footrest surface of the box-shaped footrest body made of resin having the footrest surface on which the occupant's foot rests is made lower than the shear strength of the lower region of the footrest surface.

According to the first feature, the upper region of the footrest body is crushed by the load at the time of the collision, whereby the footrest surface is tilted from the upwardly inclined position to the horizontal position, and the footrest surface is lowered. Standing is suppressed.

[0010] In the second aspect, the upper region of the footrest surface is broken by the load at the time of collision, and the standing of the footrest surface is substantially suppressed.

In any of the first and second aspects, the foot rest surface is held in a fixed position unless the foot rest body is crushed or the foot rest surface is broken. Secured. Further, the cost can be reduced because the footrest can be formed of a resin integrally molded product.

If there is a space between the footrest and the floor surface, the heel of the foot may enter this space at the time of a collision. Therefore, it is desirable to form the footrest so that the lower end of the footrest surface reaches the floor surface, and to prevent the heel portion from entering the lower side of the footrest.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a floor panel forming a floor surface 1a of a cabin of an automobile, and a toe board 2 rising diagonally forward from a front end of the floor panel 1.
And a dashboard 3 extending upward from the toe board 2 to form a partition at the lower front of the cabin.
The footrest is arranged on the toeboard surface 2a, which is a surface on the vehicle interior side, in a forwardly inclined position.

The footrest is composed of a box-shaped footrest body 4 having a footrest surface 40 on which an occupant's foot a rests and formed of a resin such as polypropylene. The footrest body 4 is formed such that the lower end of the footrest surface 40 reaches the floor surface 2a. Also, the footrest body 4
A plurality of weakening holes 42 are formed in the upper half of the left and right side plate portions 41, and the buckling strength of the upper region of the footrest body 4 is made weaker than the buckling strength of the lower region by the weakening holes 42. . The weakening hole 42 may be formed over the upper end plate 43 of the footrest main body 4. Also, the side plate portion 4
It is also possible to reduce the buckling strength of the upper region of the footrest main body 4 by forming the upper half portion 1 and the end plate portion 43 to be thin.

According to the above configuration, the foot rest surface 40 is normally used.
Is held at the fixed position shown in FIG. 2 (A), and the stability of the footrest is ensured. Further, even if the toeboard 2 is deformed rearward as shown in FIG.
That is, the upper region of the footrest body 4 is crushed by the load from the toe board 2 and the load due to the occupant's inertia, and the footrest surface 4
0 is suppressed. Further, the heel portion of the foot a is prevented from entering the lower side of the footrest.

FIG. 3 shows a second embodiment, in which the footrest body 4 is made of a solid resin product having a footrest surface 40 and has a through hole in an upper region of the footrest body 4. By forming a plurality of weakening holes 44, the buckling strength of the upper region is made weaker than the buckling strength of the lower region, and the upper region of the footrest main body 4 is crushed by a load at the time of a collision similarly to the above embodiment. I have to.

FIG. 4 shows a third embodiment. In this embodiment, a plurality of weakening holes 45 are formed in an upper region of a footrest surface 40 of a footrest body 4 formed of a resin in a box shape. The shear strength in the upper region of the mounting surface 40 is lower than the shear strength in the lower region.

According to this, the foot resting surface 4 is provided by the load at the time of collision.
The upper region 0 is broken, and the standing of the footrest surface 40 is substantially suppressed. In addition, it is also possible to make the upper region of the footrest surface 40 thin so as to reduce the shear strength.

[0019]

As is apparent from the above description, according to the present invention, the standing of the footrest surface at the time of a collision can be suppressed without impairing the stability of the footrest during normal operation, and the footrest is integrally formed. Because it is possible, cost reduction can be achieved.
