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 device for easily opening a door and rescuing an occupant even if the vehicle body is deformed by a collision.

[0002]

2. Description of the Related Art When a right front or a left front of a car collides, a front partition is moved from an engine room to a foot partition.
The passengers may rise to the room and seriously damage the legs of the occupant, and when the vehicle collides from the side, the door may be deformed and moved inward to cause serious damage to the occupant.

[0003]

In order to reduce such damage to the occupants, a reinforcing member such as a pipe is built in the door. Incorporation of the reinforcing member can prevent deformation of the door and swelling of the foot room, but it often occurs that the door does not open at the time of collision, making it difficult to rescue the occupant.

[0004] Therefore, the present invention has been conceived to facilitate 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 An automobile door reinforcing device according to the present invention is provided with a door trim at an outer surface of a door trim.
A horizontal groove is formed and a reinforcing member is closed in this groove .
It is held by a lick stop mechanism .

[0006]

FIG. 1 is a side view of FIG. 1 showing an 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 raising and lowering the door glass 5.

[0007] In motor vehicle door reinforcement device of the present invention is intended door trim 3 which is adhered to the inner plate 2 are made of synthetic resin, the transverse <br/> groove line 31 over door openings Is formed. The groove line 31, as shown in longitudinal cross-sectional view of FIG. 2, is provided with a protrusion 32 protruding toward the direction of narrowing the groove line 31. A reinforcing pipe 4 for reinforcing the door opening is fitted into the groove 31, and the reinforcing pipe 4 is supported by the projection 32 so as not to fall off the groove 31. When the reinforcing pipe 4 is strongly pulled, the groove 31 and the projection 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 cross-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 are formed in a direction perpendicular to the axis. I have.
The front pillar 6 and the center pillar 7 that hold the door body with the hinge 8 have reinforcing pipes 4.
Members 63 and 73 having projections 61 and 71 to be fitted with the holes 41 and 42 are provided respectively. Small projections 62, 72 are formed at the tips of these projections 61, 71.

When the door is closed, the reinforcing pipe 4 is held by the groove 31 of the door trim 3, and the holes 41, 42 at both ends of the pipe are projected from the pillars 6, 7.
61 and 71 are fitted. When the door is opened, the reinforcing pipe 4 is held in the groove 31 of the door trim 3 and does not hinder opening / closing of the door and getting on / off.

When an abnormal force is applied to the door opening due to the collision of the automobile, the deformation of the door opening can be prevented by the reinforcing pipe 4 to protect the occupant. Even if the reinforcing pipe 4 does not come off the pillars 6 and 7 due to the collision, the reinforcing pipe 4 is formed in the groove of the door trim 3.
The door can be easily opened without using special tools, and a sufficient gap can be secured even if the reinforcing pipe 4 remains between the pillars 6 and 7, so that the occupant can be easily removed. Can be rescued.

Further, even if a collision occurs on the opposite side, the vehicle body is deformed and the distance between the front pillar 6 and the center pillar 7 is widened, small projections 62 and 72 are formed at the tips of the projections 61 and 71. As a result, it is possible to prevent the reinforcing pipe 4 from coming off, prevent the two pillars 6 and 7 from spreading, and prevent the door from being released.

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

[0013]

As is clear from the description based on the above embodiment, the vehicle door reinforcing device of the present invention has a small number of parts, and when a vehicle collides, prevents deformation of the door and protects the occupant. The occupants can be easily rescued by opening the door.
