The vehicle body 2 is reinforced by 4.

The first reinforcing member 51 extends in the vehicle width direction and is erected on the left and right panel side portions 45, 45 of the instrument panel 42 on the side of the vehicle body 2 and is a long support body 55 supported at both ends. And a large number of polymers 56 arranged side by side in the vehicle width direction and superposed on each other in the vehicle width direction and supported by the support body 55.
By reinforcing the instrument panel 42, the vehicle body 2 in the front part of the vehicle compartment 13 is indirectly reinforced.

Each of the polymers 56 is plate-shaped, and has an axis centering in an annular shape extending in the vehicle width direction and arranged substantially coaxially, and the polymer 56 group has a rod shape extending in the vehicle width direction. Has been done. The support 55 has a support pipe 57 having a circular cross section for containing the polymer 56 group therein, and a support rod 58 having a circular cross section fitted in the inner hole of each polymer 56. The polymers 56, the support pipe 57, and the support rod 58 are made of metal or resin.

The midway portion of the first reinforcing member 51 in the longitudinal direction is supported and reinforced by the support bracket 59 and the fastener 60 on the tunnel 15 side of the vehicle body 2, and the midway portion of the support body 55 is downward. It is prevented from being largely bent. In addition, the first reinforcing member 51 includes a pair of left and right cylindrical buffer members 6 that are fitted onto the support pipe 57 of the support member 55.
1, 61 are provided.

On the other hand, the second reinforcing member 52 is displaced in the front-rear direction with respect to each of the pillars 21 to 23, and in the front-rear direction,
It is located approximately in the center between the front pillar 21 and the middle pillar 22.

Therefore, both pillars 2 adjacent to each other in the front-rear direction
Between the first and second pillars 21, the reinforcement of the vehicle body 2 by these pillars 21 and 22 tends to be relatively low, but between the two pillars 21 and 22, the second reinforcement member 52 reinforces and The strength of the vehicle body with respect to the external force on the side portions of the vehicle body 2 is made more uniform in each portion in the front-back direction of the vehicle body 2.

The second reinforcing member 52 is formed by bending a single metal pipe member having a rectangular cross section so as to have a flat gate shape in a front view. That is, the second reinforcing member 52
Is a reinforcing member main body 64 extending in the vehicle width direction over substantially the entire width of the vehicle compartment 13 at a position slightly apart from the upper surface of the floor panel 12, and is directed downward from each longitudinal end of the reinforcing member main body 64. And a lower end portion of each of the reinforcing material side portions 65 is joined to the floor panel 12.

For this reason, in the vicinity of the upper surface of the floor panel 12, the space 66 along the upper surface forms the reinforcing member main body 6
It is prevented from being divided into front and back by 4.

Therefore, as described above, even when the vehicle body strength is made more uniform, a long object which is long in the front-rear direction is housed in the space 66 along the upper surface near the upper surface of the floor panel 12 of the vehicle body 2. Therefore, the degree of freedom of storage in the vehicle compartment 13 is improved.

The third reinforcing material 53 is the second reinforcing material 5 described above.
2 is formed of a metal pipe material having the same shape and the same size as the cross section, and the reinforcing material main body 64 of the second reinforcing material 52 and the third reinforcing material 53.
The upper surfaces of the are substantially the same height.

On the other hand, the fourth reinforcing member 54 is formed of a metal pipe material having a circular cross section, and the front end of the storage cover 18 is detachably attached to the fourth reinforcing member 54.

The vehicle compartment 13 is provided with a seat device that allows the occupant 68 to be seated. This seat device includes a pair of left and right seats 69, 69 provided in the front portion of the vehicle compartment 13, a seat 70 provided in the rear portion of the vehicle compartment 13, and the front seats 6 of the seats 69, 70.
Supporting means 71 for detachably supporting 9 so as to straddle the second reinforcing material 52 and the third reinforcing material 53, and another supporting means 72 for supporting the rear seat 70 on the rear portion of the floor panel 12. Is equipped with.

Of the two seats 69, 69 on the front side, the seat 69 on the right side is the driver's seat.
An occupant 68 seated on the steering wheel 49 can steer the steering wheel 49. The left seat 69 is an auxiliary seat, and the front and rear directions of the seat 69 can be selected by the supporting means 71.

Each of the seats 69 has a seat cushion 74 supported by the supporting means 71 so as to straddle the second reinforcing material 52 and the third reinforcing material 53, and is rotated forward and backward by a rear end portion of the seat cushion 74. The seat back 75 is rotatably supported. The seat 70 on the rear side also has the same seat cushion 7 as the seat 69.
4 and a seat back 75, the seat cushion 74 is supported on the upper rear surface of the floor panel 12 by the other supporting means 72.

According to the above configuration, the seat 69 is supported on the floor panel 12 of the vehicle body 2 by utilizing the second reinforcing member 52 having sufficient strength as described above.

Therefore, the support of the seat 69 with respect to the floor panel 12 of the vehicle body 2 is achieved by a simple structure because the second reinforcing member 52 is used.

Between the above-mentioned front seats 69, 69, a shift operating lever 77 of a shift operating device is provided on the upper surface of the tunnel 15, and a parking operation is provided behind the shift operating lever 77. A brake operating lever 78 of the brake device is pivotally supported so as to be vertically rotatable.

A cover body 79 is provided for covering the longitudinal middle portions of the second reinforcing material 52 and the third reinforcing material 53 and the base portions of the gear shift operating lever 77 and the brake operating lever 78. 79 is detachably and firmly attached to the second reinforcing member 52 and the third reinforcing member 53. The support bracket 59 and the fastener 60 that support the middle portion of the first reinforcing member 51 in the longitudinal direction are supported by the cover body 79, that is, the support bracket 59 and the fastener 6 are supported.
It is firmly supported by the second reinforcing member 52 and the third reinforcing member 53 via the cover member 0.

As described above, the first reinforcement member 51 extends in the vehicle width direction and is supported at both ends on the vehicle body 2 side by the support member 55.
And a large number of polymers 5 arranged side by side in the vehicle width direction and superposed on each other in the vehicle width direction and supported by the support body 55.
6 and.

Therefore, the strength of the first reinforcing member 51 with respect to the external force from the radial direction thereof depends only on the supporting member 55 and is low, while the strength from the outer side of the vehicle body 2 is small. The strength of the external force in the axial direction, which is the external force, depends on both the support 55 and the group of rod-shaped polymers 56 superposed on each other in the vehicle width direction.
High strength is secured.

Therefore, when the occupant 68 seated on the seat 69 comes into contact with the first reinforcing member 51 at the time of "front collision",
The direction of the external force applied to the first reinforcing member 51 is in the radial direction (normal direction) of the first reinforcing member 51, and the strength in this direction is low as described above,
The first reinforcing member 51 is easily bent or deformed, or bent, so that the occupant 68 is prevented from receiving a large load from the first reinforcing member 51.

On the other hand, on either the left or right side portion of the vehicle body 2, at the time of "side collision", the side portion of the vehicle body 2 receives an external force directed from the outside toward the vehicle width direction. Is the same as the axial direction of the first reinforcing member 51, and since the strength in this direction is high as described above, the first reinforcing member 51 opposes the external force with the high strength, Therefore, the strength of the vehicle body with respect to the above-mentioned "side impact" can be sufficiently improved.

In the vertical direction, the first reinforcing member 51
Is positioned near the upper surface of the seat cushion 74 of the seat 69, that is, the first reinforcing member 51 is positioned near the front of the knee of the occupant 68 seated on the seat cushion 74 of the seat 69.

By the way, as described above, in the vertical direction,
The first reinforcing member 51 is used as the seat cushion 7 of the seat 69.
4 near the upper surface of the occupant 4, the occupant 6 sitting on the seat cushion 74 of the seat 69 at the time of “front collision”.
Since the knee of No. 8 has a high possibility of contacting the first reinforcing member 51 at a relatively early stage and is generally not preferable, the first reinforcing member 51 has been conventionally used in the vertical direction in the seat. The seat cushion 74 is located at a position considerably higher than the upper surface of the seat cushion 74.

However, as described above, at the time of "front collision",
When the knee of the occupant 68 comes into contact with the first reinforcing member 51, the first reinforcing member 51 is immediately deformed to prevent a large load from being applied to the knee of the occupant 68. There is.

Therefore, as described above, the first reinforcing member 51 is attached to the seat cushion 7 of the seat 69 in the vertical direction.
4 is located in the vicinity of the upper surface of the vehicle 4, that is, it is located at a low position. As a result, a surplus space is generated at the front end portion of the vehicle compartment 13, and a large storage space 46 is provided by utilizing the surplus space.

Since the outer shell of the first reinforcing member 51 is composed of the buffer 61 as described above,
It is more reliably prevented that the reinforcement member 51 applies a large load to the knees of the occupant 68.

In a side view, each end of the first reinforcing member 51 is located within the front end of the door opening 35.

Therefore, at the time of "side collision", the door opening 3
The door 36 closing 5 receives the external force and the door opening 3
When trying to enter the vehicle compartment 13 side through the door 5, the door 36 comes into immediate contact with the end portion of the first reinforcing member 51. At this time, the first reinforcing member 51 receives an external force from the door 36 in the axial direction thereof, but the first reinforcing member 51 has a high strength with respect to the external force from the axial direction as described above. Therefore, the first reinforcing member 51 sufficiently opposes the external force from the door 36.

Further, in a side view, at least a part of the side portion of the second reinforcing member 52 is located inside the lower end portion of the door opening 35.

Therefore, as described above, the door opening 35
The door 36 closing the door receives the external force and the door opening 35 is closed.
When attempting to enter the vehicle compartment 13 side through the door, the door 36 immediately contacts the side portion of the second reinforcing member 52.

At this time, the second reinforcing member 52 is used for the passenger compartment 13
Extending in the vehicle width direction over the entire width thereof, both ends thereof being supported by the floor panel 12 at both ends, and the second reinforcing member 52 is provided with respect to external force from the outside of the vehicle body 2 (external force from the door 36). Since it has sufficient strength, the second reinforcing member 52 sufficiently opposes the external force from the door 36.

Therefore, the entrance of the door 36 into the passenger compartment 13 side through the door opening 35 is more reliably prevented and the occupant 68 is protected.

Moreover, the respective end portions of the first reinforcing member 51 and the second reinforcing member 52 have respective front seats 69 in the vehicle width direction.
It is located on the outer side of the outer edge of the vehicle. Therefore, as described above, the door 36 that has entered the vehicle compartment 13 side reaches the occupant 68 seated on the seat 69 because the door 36 causes the first reinforcing member 51 and the second reinforcing member 52 to reach each other. The occupant 68 is restrained by coming into contact with the end portion, and the occupant 68 is protected more reliably.

The door 36 is inserted by the first reinforcing member 51 and the second reinforcing member 52.
Since it is prevented by two points of the front part and the lower part of 6, the door 36
Is more reliably suppressed.

Although the above is based on the illustrated example, the first
The reinforcing member 51 may be directly supported by the left and right pillars 21 and 21 of the vehicle body 2. Further, each of the polymers 56 of the first reinforcing member 51 may be connected to each other only partially in the circumferential direction, and may be, for example, a coil spring having a rectangular cross section. Further, only one of the support pipe 57 and the support rod 58 forming the support 55 of the first reinforcing member 51 may be provided.

Each end portion of the second reinforcing member 52 may be directly connected to the inner panel 10 of each side sill 8 instead of the floor panel 12 or together with the floor panel 12. By doing so, each side sill 8 has sufficient strength and rigidity, so that the second reinforcing member 5 is
The strength and rigidity of No. 2 are sufficiently improved, and the dimension of the space 66 in the vehicle width direction is further widened, so that the degree of freedom in storage is further improved. Further, the entry of the door 36 into the vehicle compartment 13 side is also prevented at an earlier stage.
However, the second reinforcing member 52 is not essential to the present invention.

[0072]

The effects of the present invention are as follows.

According to the first aspect of the present invention, there is provided a reinforcing member extending in the vehicle width direction along the front end portion of the vehicle interior inside the vehicle body, and a rear side of the reinforcing material is provided with a seat in the vehicle interior of an automobile body. In the reinforcement structure in the front of the passenger compartment,

The reinforcing material extends in the vehicle width direction and is provided in parallel with the elongated support body whose both ends are supported on the vehicle body side in the vehicle width direction and overlaps each other in the vehicle width direction. And a number of plate-like polymers supported.

Therefore, the strength of the reinforcing material with respect to the external force from the radial direction thereof is almost dependent on the support body and is low, while the strength in the axial direction which is the external force from the outer side of the vehicle body. The strength with respect to the external force depends on both the above-mentioned support and the rod-shaped polymer group superposed on each other in the vehicle width direction, and high strength is secured.

Therefore, when the occupant seated on the seat comes into contact with the reinforcing member at the time of "front collision", the direction of the external force applied to the reinforcing member is in the radial direction of the reinforcing member, Since the strength in this direction is low as described above, this reinforcing material is easily bent or deformed or bent, and the occupant is prevented from receiving a large load from the reinforcing material. .

On the other hand, at the time of "side collision", the side portion of the vehicle body receives an external force directed from the outside toward the vehicle width direction,
The direction of this external force is the same as the axial direction of the reinforcing member, and the strength in this direction is high as described above, so the reinforcing member resists the external force with its high strength,
Therefore, the strength of the vehicle body with respect to the above-mentioned "side impact" can be sufficiently improved.

According to the second aspect of the present invention, the reinforcing material is positioned in the vertical direction in the vicinity of the upper surface of the seat cushion of the seat, and has the following effect.

That is, as described above, when the reinforcing material is positioned near the upper surface of the seat cushion of the seat in the vertical direction, the knee of the occupant seated on the seat cushion of the seat at the time of "front collision" is generated. Since the possibility of contacting the reinforcing member at a relatively early stage is high and is generally unfavorable, conventionally, the reinforcing member is in the vertical direction and is considerably higher than the upper surface of the seat cushion of the seat. Is located in.

However, in the present invention, when the knee of the occupant comes into contact with the reinforcing member at the time of "front collision", the reinforcing member is immediately deformed as described above, and a large load is applied to the lap of the occupant. Are prevented from being given.

Therefore, as described above, the reinforcing member is positioned in the vicinity of the upper surface of the seat cushion of the seat in the vertical direction, that is, it is positioned lower.
A surplus space can be created at the front end of the passenger compartment, and a large storage space can be provided by utilizing this.

According to a third aspect of the present invention, there is provided a vehicle having a door opening formed in a side wall of the vehicle body and a door for opening and closing the door opening.

In a side view, the end portion of the reinforcing member is located inside the door opening.

Therefore, at the time of "side collision", when the door closing the door opening receives an external force and tries to enter the passenger compartment through the door opening, the door immediately contacts the end portion of the reinforcing member. It comes into contact. At this time, the reinforcing material receives an external force from the door in the axial direction thereof, but the reinforcing material has a high strength with respect to the external force from the axial direction as described above. It will sufficiently oppose the external force from the door.

Therefore, the entrance of the door into the passenger compartment through the door opening is more reliably prevented.
