Abstract

PURPOSE: To provide an automotive door reinforcing device facilitating opening a door while protecting an occupant at collision time. CONSTITUTION: A grooved streak 31 in a horizontal direction is formed in the external surface of a door trim 3, and a reinforcing member of pipe 4 or the like is fitted, so as to prevent dislocating it in an ordinary use condition, into this grooved streak 31.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door reinforcing device, and more particularly to a vehicle door reinforcing device which can open a door and rescue an occupant even if the vehicle body is deformed due to a collision.

[0002]

2. Description of the Related Art When a right front or a left front of a vehicle collides, the front bulkhead moves from the engine room to the foot
It may rise toward the room and seriously damage the legs of the occupant, or the vehicle may be deformed and moved inward to be seriously damaged by the side impact of the vehicle.

[0003]

In order to reduce the damage to the occupant, a reinforcing member such as a pipe is built in the door. If the reinforcing member is built in, the deformation of the door and the swelling of the foot room can be prevented, but the door often fails to open at the time of a collision, and it is difficult to rescue the occupant.

Therefore, the present invention was devised to facilitate the opening of the door in the event of a collision even if a reinforcing member is attached to the door.

[0005]

SUMMARY OF THE INVENTION The vehicle door reinforcing device of the present invention has a lateral groove formed on the outer surface of the door trim so that the reinforcing member does not come off in this groove in normal use. It is something that has been fitted.

[0006]

EXAMPLE A side view of FIG. 1 showing the inner surface of a door and FIG.
As shown in the vertical sectional view of FIG. 1, the door body includes an outer plate 1, an inner plate 2, a door trim 3 to which an arm rest 33, a door handle 34 and the like are attached, a door glass 5,
It is composed of a mechanism for moving the door glass 5 up and down.

In the automobile door reinforcing apparatus of the present invention, the door trim 3 attached to the inner plate 2 is made of synthetic resin and has the groove 31 formed in the lateral direction. As shown in the cross sectional view of FIG.
The projection 32 is provided so as to project in the direction in which the 31 is narrowed. A reinforcing pipe 4 for reinforcing the door opening is fitted in the groove 31, and the reinforcing pipe 4 is supported by the projection 32 so as not to fall off from the groove 31. When the reinforcing pipe 4 is strongly pulled, the groove 31 and the protrusion 32 expand and can be removed. That is, the reinforcing pipe 4 is held in the groove 31 by the click / stop mechanism.

As shown in the transverse sectional view of FIG. 3, holes 41 are formed at both ends of the reinforcing pipe 4 along an arc centered on the hinge 8 and holes 42 in a direction orthogonal to the axis. There is.
The front pillar 6 and the center pillar 7 that hold the door body with the hinges 8 have reinforcing pipes 4
Members 63 and 73 having protrusions 61 and 71 that fit into the holes 41 and 42 are provided, respectively. Small protrusions 62, 72 are formed at the tips of these protrusions 61, 71.

When the door is closed, the reinforcing pipe 4 is held in the groove 31 of the door trim 3, and the holes 41 and 42 at both ends of the pipe are protruded from both pillars 6 and 7.
It is fitted with 61 and 71. When the door is opened, the reinforcing pipe 4 is held by the groove 31 of the door trim 3, so that it does not hinder the opening and closing of the door and the entry and exit of the door.

When a vehicle collides and an abnormal force is applied to the door opening, the reinforcing pipe 4 prevents deformation of the door opening and protects an occupant. Even if the reinforcing pipe 4 bites into both pillars 6 and 7 and does not come off due to a collision, the reinforcing pipe 4 is not affected by the groove of the door trim 3.
Since it can be easily removed from 31, the door can be easily opened without using a special tool, and even if the reinforcing pipe 4 remains between the pillars 6 and 7, a sufficient gap can be secured, which facilitates the occupant. Can be rescued.

Even when the front body 6 is deformed and the vehicle body is deformed to widen the distance between the front pillar 6 and the center pillar 7, small projections 62, 72 are formed at the tips of the projections 61, 71. Since the reinforcing pipe 4 does not come off, it is possible to prevent the expansion between the pillars 6 and 7 and prevent the door from being released.

If a turnbuckle is used as the reinforcing pipe 4, even if the door opening is deformed due to a collision, it can be easily removed by rotating and loosening the turnbuckle.

[0013]

As is apparent from the description based on the above embodiments, the vehicle door reinforcing apparatus of the present invention has a small number of parts and prevents deformation of the door when an automobile collides to protect an occupant. You can easily open the door and rescue the occupants.
