Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door for protecting an occupant from an impact from the outside of the vehicle body.

[0002]

2. Description of the Related Art Conventionally, a door inner panel is arranged inside a door outer panel of a vehicle body, and a side beam is arranged inside the door outer panel along the front-rear direction of the vehicle body. A car door is known in which a guide rail of a window regulator is provided on the inside, a door trim that accommodates a shock absorber is provided inside the door inner panel, and the periphery of the door inner panel is fixed inside the periphery of the door outer panel. ..

[0003]

However, in the conventional automobile door, since the guide rail of the window regulator is attached to the outside of the door inner panel, the inside of the side beam between the door outer panel and the door inner panel is eliminated. There is no space for the shock absorber, and the shock absorber must be placed inside the vehicle body of the door inner panel, and the place where the shock absorber of the door trim is stored bulges inward more than the door inner panel. As a result, the thickness of the entire door is increased due to the shock absorber.

The object of the present invention is to solve the above-mentioned problems, and when the outer door panel is impacted from the outside of the vehicle body, the side beams are subjected to the impact from the outer side of the vehicle body to the inside of the vehicle body of the outer door panel. It suppresses invasion to people, secures the occupant's living space with side beams, the impact absorber stored in the door trim absorbs impact energy from the outside of the vehicle body, protects the occupant from the impact energy with the impact absorber,
Install the guide rail of the window regulator inside the side beam to allow space inside the side beam between the door outer panel and the door inner panel, and place the shock absorber between the door outer panel and the door inner panel. Placed in the space inside the side beam, the place where the shock absorber of the door trim is stored does not bulge inwardly of the car body than the inner door panel as in the past, and the thickness of the entire door absorbs shock. An object of the present invention is to provide an automobile door that can effectively utilize the space inside the side beam between the door outer panel and the door inner panel without increasing the size of the body.

[0005]

A vehicle door according to the present invention has a door inner panel disposed inside a door outer panel of the vehicle body, and is provided inside the door outer panel along the front-rear direction of the vehicle body. With side beams,
A guide rail of a window regulator is provided inside the side beam, and a door trim that accommodates a shock absorber facing the inside of the guide rail is provided inside the door inner panel. is there.

[0006]

When the door outer panel of the vehicle body receives an impact from the outside of the vehicle body, the side beams arranged inside the door outer panel along the front-rear direction of the vehicle body cause the outside beam of the vehicle body to be affected by the impact from the outside of the vehicle body. The shock absorber is stored inside the door trim on the door trim inside the door inner panel, which is located inside the door outer panel to prevent the vehicle from entering the inside. Protects passengers by absorbing impact energy from outside.

[0079]

As described above, according to the door of the automobile of the present invention, when the door outer panel is impacted from the outside of the vehicle body, the side beam is caused by the impact from the outside of the vehicle body. Since the inside of the car body is suppressed, the living space for the occupant can be secured by the side beam, and the shock absorber housed in the door trim absorbs the impact energy from the outside of the car body, so The absorber can protect against impact energy.

Further, since the guide rail of the window regulator is attached to the inside of the side beam, a space is obtained inside the side beam between the door outer panel and the door inner panel, and the shock absorber is used as the door outer panel. It can be placed in the space inside the side beam between the door inner panel and the place where the shock absorber of the door trim is stored can bulge more inward than the door inner panel. Since the thickness of the entire door does not increase due to the shock absorber, the space inside the side beam between the door outer panel and the door inner panel can be effectively used.
