CONSTITUTION: An impact pad assembly for a vehicle(10) comprises a foam impact pad(11) and a steel plate(12). The foam impact pad is installed in the inner surface of the door trim, thereby absorbing. The steel plate is inserted to the inner side of the foam impact pad, thereby being installed. The steel plate disperses the impact to the foam impact pad.

Description

Impact pad assembly for vehicle

The present invention relates to a side shock absorbing assembly of a vehicle, and more particularly, to an impact pad assembly for a vehicle installed inside the door of a vehicle.

In general, the door of the vehicle comprises a door trim and a door panel. When an impact is applied to the door of the vehicle, the door trim and the door panel of the door are all impacted. At this time, the door trim or door panel constituting the door enters the interior of the vehicle, causing injury to the occupants.

Therefore, in order to absorb the amount of impact applied to the door of the vehicle, a cushioning member is provided between the door trim of the door of the vehicle and the door panel. At this time, the shock absorbing member installed in the door is removed from the door when the shock is applied to the door side of the vehicle. The foam cushioning member serves to reduce the impact on the body of the occupant.

However, such a conventional shock absorbing member has a relatively good dispersion of impact force when the impact force is perpendicular to the center of the shock absorbing member. However, when the amount of impact on the shock absorbing member is inclined to or surrounds the shock absorbing member, the shock absorbing amount of the shock absorbing member is good. There is a problem that could not be.

To this end, an impact dispersion panel formed of hard plastic or metal is attached to one side of the buffer member in contact with the door panel using an adhesive or the like. However, the impact dispersion panel attached to one side of the shock absorbing member is contaminated by dust and moisture introduced into the door, thereby deteriorating impact absorption performance.

In addition, when the impact dispersion panel is a hard plastic material, the impact dispersion panel is broken due to the applied shock. On the other hand, when the impact dispersion panel is made of a metal material, corrosion occurs due to moisture, and rust is generated, thereby causing a problem of deteriorating the appearance of the room by flowing down the generated rust.

Therefore, even if the impact force is applied to any position of the cushioning member to be foam-molded, the deformation is made uniform so that the shock absorption is good and the performance of the side shock absorbing assembly of the vehicle is improved, without deterioration in performance due to contamination or corrosion. need.

Embodiments of the present invention provide a impact pad assembly for a vehicle that facilitates shock absorption by dispersing an impact regardless of a location where an impact is applied during a side collision of the vehicle.

In addition, it is to provide a vehicle impact pad assembly with improved durability by preventing performance degradation due to contamination or corrosion.

According to an aspect of the present invention, the impact pad is attached to the inner surface of the door trim absorbs the impact force, and is disposed and inserted into the foam impact pad, and includes a steel plate for dispersing the impact force applied to the impact pad An impact pad assembly for a vehicle may be provided.

Embodiments of the present invention can protect the occupant's body by dispersing the impact force by the steel plate arranged to be inserted into the foam impact pad during the side impact of the vehicle.

In addition, by preventing the contamination of the steel plate from dust and moisture can be significantly improved impact absorption.

In addition, it is possible to prevent the separation of the steel plate from the foam impact pad to significantly improve the durability.

1 is a state diagram of a door trim mounted with an impact pad assembly for a car according to an embodiment of the present invention.
FIG. 2 is a cross-sectional view taken along line AA of FIG. 1.

1 is a state diagram of a door trim 20 in which an impact pad assembly 10 for a vehicle is installed according to an embodiment of the present invention. 2 is a cross-sectional view taken along the line A-A of FIG.

1 and 2, the impact pad assembly 10 for a vehicle includes a foam impact pad 11.

The foam impact pad 11 is disposed on the inner surface of the door trim 20 of the vehicle. In this case, the foam impact pad 11 may be disposed to correspond to a position where the occupant is likely to be injured during a side collision of the vehicle. For example, the pelvis and the thigh portion of the occupant may be disposed to correspond, but are not limited thereto.

On the other hand, the foam impact pad 11 may be formed with at least one fastening hole (13). In addition, at least one boss portion 14 which may be deformed by heat may be formed on an inner surface of the door trim 20. Therefore, at least one boss 14 formed on the inner surface of the door trim 20 may be inserted into the at least one fastening hole 13 of the foam impact pad 11 to be fastened by heat fusion.

The impact pad assembly 10 for a vehicle includes a steel plate 12. At this time, the area of the steel plate 12 may be formed smaller than the area of one side of the foam impact pad (11). That is, the area of the steel plate 12 may be an area of a size obtained by reducing the size of the area of the one side of the foam impact pad 11 at a predetermined ratio.

The steel plate 12 is disposed in a predetermined depth S from the one side of the foam impact pad 11.

At this time, the method of drawing the steel plate 12 into the foam impact pad 11, the groove (not shown) is formed in the foam impact pad 11 to insert the steel plate 12, or the steel in the molding die The plate 12 may be formed in the foam impact pad 11 so as to be drawn at a predetermined depth S from the one side, and may be foam molded, but is not limited thereto.

Hereinafter, a method in which the steel plate 12 is inserted into the foam impact pad 11 for convenience of description may include a steel plate 12 in a molding die from the one side of the foam impact pad 11 at a predetermined depth S. It will be mainly described that the foam molded after the arrangement so as to be drawn into.

The steel plate 12 may be foam-molded after arranging the steel plate 12 to be introduced into the molding die of the foam impact pad 11 so as to be drawn in a predetermined depth S from the one side.

At this time, the depth (S) that the steel plate 12 is drawn in the foam impact pad 11 may be at least the steel plate 12 thickness (T) from the one side. Thus, the steel plate 12 is not exposed to the outside.

When the impact pad assembly 10 for a vehicle as described above is applied to the impact pad 11, the impact force is dispersed by the steel plate 12 is inserted into the foam impact pad 11 to a predetermined depth (S) do.

Therefore, even when the impact force applied to the foam impact pad 11 does not act perpendicular to the one side, it is evenly distributed on the entire surface of the foam impact pad 11 by the steel plate 12 to protect the occupant. have.

In addition, as the steel plate 12 is disposed in a predetermined depth S into the foam impact pad 11, the steel plate 12 may be prevented from being rusted by corrosion or dust, which is introduced into the door trim 20. Can be. Therefore, the impact force absorption can be significantly improved, and rust generated in the steel plate 12 can also be prevented from flowing into the room.

In addition, the steel plate 12 may be prevented from being separated from the foamed impact pad 11 in the process of absorbing the impact applied by the foamed impact pad 11 to reduce the amount of impact. Therefore, durability of the impact pad assembly 10 for a vehicle may be improved.

As mentioned above, although embodiment of this invention was described, the person of ordinary skill in the art should add, change, delete, add, etc. the component within the range which does not deviate from the idea of this invention described in the claim. The present invention may be modified and changed in various ways, which will also be included within the scope of the present invention.
