ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a door of a vehicle, and more particularly to a door structure of vehicle adapted to install a pushing member in a door to reduce a damage to sides of a passenger during side collision of a vehicle, thereby providing a maximum safety to the passenger.
2. Description of the Prior Art
Generally, a vehicle is equipped with a door hinged to a body of the vehicle for a passenger to get in and out of the vehicle and the door
10
is manufactured as illustrated in
FIGS. 1 and 2
with an outer panel
11
and an inner panel
12
. The inner panel
12
is attached with a trim material
13
as inside material, which is then assembled with an arm rest
14
of protruding shape and the arm rest
14
is attached thereunder with a door pocket
15
for accommodating less voluminous small stuffs.
Meanwhile, the door
10
is so manufactured as to reinforce a structural strength to provide a safety to a passenger when a vehicle is laterally collided. In other words, an inner space formed by the outer panel
11
and the inner panel
12
is arranged with a reinforcing member
16
which is vertically attachable along a horizontal direction of the door
10
, as illustrated in FIG.
3
. The reinforcing member
16
vertically arranged along the horizontal direction of the door
10
serves to absorb an external shock applied from the door
10
when a vehicle is side-collided and to reduce deformation of the door
10
, thereby promoting safety of a passenger.
However, there is a problem in that, even when the vehicle is equipped with the reinforcing member
16
at the door
10
, some safety regulations regarding the sides of the upper torso of a passenger during a side collision of a vehicle (a European regulation limiting to within 42 mm of a deformation relative to a side of a dummy corresponding to ribs of a human body during a side collision of a vehicle) cannot be fully satisfied. This is because a two-panel door comprised of an outer panel
11
and an inner panel
12
is essentially compressed into a single-panel door instantaneously by the shock force created by a side impact collision. The resulting single-panel door transmits the shock force of the side impact collision directly to the upper torso of a passenger.
In other words, there is a limit in satisfying the related regulations by reducing injuries to the human body according to reinforcement of structural strength to the door
10
. There is a need to satisfy the related regulations by reducing injuries to the human body during side collision of a vehicle through other countermeasures outside of the reinforcement of the structural strength and to promote safety to the passenger as well.
SUMMARY OF THE INVENTION
The present invention is disclosed to solve the aforementioned problems and it is an object of the present invention to provide a door structure of a vehicle adapted to transmit a mild shock first to a passenger before a two-panel door is transformed to a one-panel door by shock during a side collision of a vehicle, pushing the position of the passenger, such that a further stronger shock thereafter cannot reach the human body directly thereby reducing injury to the passenger.
In accordance with the objection of the prevent invention, there is provided a door structure of a vehicle, the structure comprising:
a main body unit frontly opened at an inner side surface of an outer panel at the door;
a bent side wall unit extended from a periphery of the main body unit to form a predetermined space;
a pushing member integrally formed with a flange unit extended from the bent side wall unit and bent outwardly, so as to face the torso of a passenger.
