Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock-absorbing pad mounting structure for an automobile, and more particularly to a structure for securing the shock-absorbing function of the pad while ensuring stable mounting.

[0002]

2. Description of the Related Art Recently, there has been proposed a technique of providing an impact bar in a side door and an impact absorbing pad such as a synthetic resin foam body in order to enhance protection of an occupant in a side collision in which a vehicle collides from the side of an automobile. It is being adopted. The impact absorbing pad is usually arranged at a height position corresponding to the waist of the occupant. If this pad is not provided, the outer panel crushes during a severe side impact and reaches the inner panel through the parts installed inside the door, and at the next moment, the inner panel collides with the passenger inside the vehicle through the door trim. Therefore, the impact force on the occupant is impacted with a delay. On the other hand, in the case of providing a pad, at the time of a side collision, the pad pressed by the outer panel passes through the opening formed in the inner panel and the door trim, and the outer panel passes through the parts inside the door as described above. The occupant is pressed early before contact with the inner panel. That is, since the collision load is transmitted to the occupant at an early stage and the impact load is sufficiently absorbed by the pad, the impact force acting on the occupant is remarkably reduced.

Therefore, the mounting structure for mounting the shock absorbing pad has a stable supporting function so that the pad does not drop out due to vibration of the vehicle body and the function of allowing the pad to move relative to the panel member of the side door at the time of a side collision. And are required.
That is, as described above, it is necessary to move the pad relatively to the vehicle compartment side with respect to the door panel member, particularly the inner panel, in order to fully exert the shock absorbing function of the pad. For example, Japanese Patent Laid-Open No. 6-270681 discloses a mounting structure for mounting pads via holding members that hold the front and rear side surfaces and the upper surface of the shock absorbing pad, and the front and rear side surfaces and the left and right side surfaces of the shock absorbing pad. There are described a mounting structure for mounting the pad via a holding member for holding the pad, a mounting structure for mounting the pad via a cap-shaped holding member fitted onto the top of the shock absorbing pad, and the like.

[0004]

In the conventional pad mounting structure and the pad mounting structure of the above-mentioned publication, the holding member is large and heavy, and the manufacturing cost is disadvantageous, and the holding force for holding the shock absorbing pad is large. Since the pad is strong, it is difficult for the pad to move relative to the panel member at the time of a side collision, and the like. In particular, the conventional mounting structure employs a structure in which the outer surface of the pad is supported by a holding member, so that the holding member has a small and simple structure that is easily deformed by a small load,
It was impossible to hold the pad strongly. An object of the present invention is to miniaturize the holding member and simplify its structure, to enable the shock absorbing pad to be stably supported, and to promote relative movement of the pad with respect to the panel member of the side door at the time of a side collision. , Etc.

[0005]

According to a first aspect of the present invention, there is provided a shock absorbing pad mounting structure for a vehicle, wherein the shock absorbing pad is provided inside a side door of the vehicle. A holding member for supporting the peripheral edge portion is provided along the portion, and mounting portions for attaching to the panel member of the side door are provided at both ends of the holding member.

Since the holding member is disposed along the peripheral edge portion of the impact absorbing pad substantially orthogonal to the load receiving surface to hold the peripheral edge portion of the impact absorbing pad, the peripheral edge portion of the impact absorbing pad is easily broken during a side collision. Since the pad easily moves relative to the panel member of the side door, the shock absorption is excellent. Further, since the mounting portions at both ends of the holding member are mounted on the panel member of the side door, the shock absorbing pad can be stably supported on the side door.

It has been done. As described above, since the shock absorbing pad is embedded in the peripheral portion of the shock absorbing pad by insert molding, the binding force between the holding member and the shock absorbing pad can be secured even if the holding member is downsized to the minimum necessary. It is possible to secure the stability of support for supporting the with the holding member. In addition, the same operation as in claim 1 is achieved.

According to a third aspect of the present invention, in the second aspect of the present invention, the holding member is formed of a thin metal plate whose thickness direction is the load acting direction. Therefore, since the holding member is easily deformed with a small load, the relative movement of the impact absorbing pad with respect to the panel member of the side door can be promoted through the deformation of the holding member in the event of a side collision. Other effects are the same as those of the second aspect.

According to a fourth aspect of the invention, there is provided a shock absorbing pad mounting structure for an automobile according to the third aspect of the invention, wherein the holding member is formed as an integral part that is continuous from one mounting portion to the other mounting portion. Therefore, the number of parts of the holding member is the minimum,
The structure is simple and the manufacturing and assembly costs can be reduced. The other operation is the same as that of the third aspect.

According to a fifth aspect of the present invention, there is provided a shock absorbing pad mounting structure for an automobile according to any one of the second to fourth aspects, wherein the holding member is approximately one of the peripheral portions of the entire circumference of the shock absorbing pad. It is constructed so as to support a half portion. Therefore, the relative movement of the impact absorbing pad with respect to the panel member of the side door at the time of side collision can be further promoted, and the holding member can be reduced in size and weight. Other operations similar to those of any one of claims 2 to 4 are achieved.

According to a sixth aspect of the invention, in the fifth aspect of the invention, the holding member is provided along the lower peripheral edge of the shock absorbing pad. Therefore, the shock absorbing pad can be stably supported by the holding member.
