[Prior Art] The joint between the windshield support part of the front pillar and the fender plate or dash plate is also the part where the upper hinge of the front door is attached.
Sufficient strength is required. However, since the structure generally consists of only one reinforcing plate superimposed between the pillar outer plate and the pillar inner plate, when the front door is opened and is blown by the wind, the hinge support of the vehicle body There is a risk that it may become twisted and deformed. Furthermore, even if the fender plate is crushed rearward during a frontal collision, which is relatively minor, the front pillar may be deformed and the windshield may be damaged.

As a reinforcement structure for a front pillar, for example, as disclosed in Japanese Utility Model Application Publication No. 55-36055, there is a structure in which a plate material constituting a front deck is joined to the outside of a front pillar with a closed cross section to form a closed cross section. However, this has the disadvantage that the cross-sectional shape of the front pillar becomes larger, which spoils the appearance of the car body.

In the front pillar disclosed in Japanese Patent Application Laid-Open No. 54-146321, an inner pillar plate is superimposed on the inside of a pillar outer plate (vehicle body side wall plate) that partitions the door opening, and a reinforcing plate is superimposed on the outer side of the pillar outer plate. They are simply connected to form a closed cross section. Pillar outer plate,
The pillar inner plate and the reinforcing plate are continuous from the roof portion to the side sill portion, and reinforcement is not focused on areas where it is particularly necessary. Therefore, to prevent the front pillar from twisting when the front door is blown by the wind, or from deforming the front pillar and damaging the windshield during a frontal collision,
No structure for reinforcing the front pillar is disclosed.

[Effects of the invention] As described above, the present invention includes an upper reinforcing plate disposed from the lower half of the front pillar to the upper door hinge attachment area, and an upper reinforcing plate disposed from the lower end of the front pillar to the side sill area. The lower part of the upper reinforcing plate and the upper part of the lower reinforcing plate overlap each other, and the edges of the inner pillar plate, upper and lower reinforcing plates, and outer pillar plate are separated at the overlapped part. Since the four panels are stacked together and combined into three closed cross sections, the rigidity of the front pillar against torsion and bending is strengthened, and the front door is pushed forward and the area around the hinge support of the front pillar is twisted, and in the event of a frontal collision, the front pillar will be able to withstand the twisting and bending of the front pillar. This prevents the front pillar from being crushed and damaging the windshield.

The stress that acts on the hinge support when opening and closing the front door is dispersed between the upper and lower reinforcement plates, reducing the strength burden on the vehicle body and preventing the front door from overlapping due to deformation of the hinge support when the front door is opened. Strokes are prevented.
