Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a side body structure of an automobile.
[0002]
[Prior art]
Conventionally, in a vehicle in which the side door formed on the side of the vehicle, such as a three-door vehicle or a two-door vehicle, is configured with only one door on one side, the passenger can enter and exit the rear seat and load and unload the luggage. The access uses a seat walk-in structure in which the front seat is slid forward and the back of the front seat is tilted to access the rear seat. A narrow space with the end will be used. In addition, this series of operations is necessary and complicated even when a small load is taken in and out of the rear seat (for example, see Japanese Patent Application Laid-Open No. 59-216738).
[0003]
For this reason, it is conceivable to widen the door opening rearward to improve the accessibility to the rear seat.However, when the door opening widened rearward is provided, the pillars are lowered rearward accordingly. Since there is no rigid member corresponding to the side collision on the side of the seat, the safety against the side collision of the front seat occupant is reduced. And in order to ensure the safety of the side collision, a reinforcing structure is required, which causes problems such as an increase in the weight of the door and an increase in cost.
[0004]
