BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, referring to FIGS. 1 to 5, FIG. 1 shows a developed state before attaching and fixing the side impact cushioning pad 1 to the inner side surface 2a of the lining substrate 2. Among the members, the side impact cushioning pad 1 is resin-molded from synthetic resin such as polypropylene and polyester. The lining substrate 2 is injection-molded from a synthetic resin such as polypropylene or ABS resin.

The side impact cushioning pad 1 is formed in a bottomed casing shape in which the tip end side is open and the side faces 10 to 13 are quadrilateral.
The inner surface of the lining substrate 2 is formed to have a predetermined rising dimension toward the door inner panel (not shown). The side collision cushioning pad 1 is provided with a stop hole 14 on a lower side surface 13 for engaging a hooking claw of a projection piece described later.

The lining substrate 2 is provided with a rising plate 20 having plate surfaces applied to side surfaces 20a ... 20c extending over a plurality of surfaces of the side impact cushioning pad 1 to receive and support each side surface, and a hook claw 21a on the side of the protrusion. A projection piece 21 that meshes with the remaining side surface 20d of the bump cushioning pad 1 to receive and support the side surface is integrally resin-molded so as to project from the inner surface. The rising plate 20 and the protruding piece 21 are each formed to have a rising dimension smaller than the rising dimension of the side impact cushioning pad 1.

The rising plate 20 is formed in a frame shape in which three sides 20a to 20c are fitted to the upper side surface 10 and the left and right side surfaces 11 and 12 of the side impact cushioning pad 1. Further, lower end sides 20d and 20e for continuously receiving and supporting the lower side surface end portions of the side impact cushioning pad 1 from the left and right side edges 20b and 20c are continuously formed. The rising plate 20 has both lower end sides 20d and 20e.
Are formed to be spaced apart from the inner bottom surface 2b of the lining substrate 2.

The projecting piece 21 has a hook 2a that rises from the rising portion 2a.
It is formed so as to project laterally upward on the tip end side of 1d. In addition, the protrusion 21 is formed such that the upper side surface of the rising portion 21d is flush with the inner surfaces of the lower end sides 20d and 20e of the rising plate 20 and within the interval between the lower end sides 20d and 20e. It is preferable that two or more protrusions 21 are provided in parallel to each other, and that they are integrally formed so that the longitudinal direction of the rising portion 21b is supported by the rib 2c protruding from the inner surface of the lining substrate 2.

In order to attach the side impact cushioning pad 1 to the automobile door lining based on the above-mentioned lining substrate 2, the side impact cushioning pad 1 is provided inside the rising plate 20 continuous from both lower end sides 20d and 20e in a frame shape. Forcibly press in from the bottom side. During this process, the protruding piece 21 has the rising portion 21.
b is supported by the ribs 2c and does not flex and deform, and the latching claws 21a slide along the lower side surface 13 of the side impact cushioning pad 1, and the lower side surface 13 of the side impact cushioning pad 1 flexibly deforms. Stop hole 1 of side impact buffer pad 1
4 can be moved to the latch claw 21a.

When the hooking claw 21a of the protruding piece 21 meshes with the stop hole 14 of the side impact cushioning pad 1, the lower side surface 13 of the side impact cushioning pad 1 is elastically restored to its original shape as shown in FIG.
The side impact cushioning pad 1 is fitted into the inside of a standing plate 20 that is continuous in a frame shape from both lower ends 20d and 20e. Further, since the hooking claws 21a of the projecting pieces 21 are engaged with the stopper holes 14 of the lower side surface 13, the peripheral side surfaces 10 to 13 are raised.
0 and the protruding piece 21 are pressed and attached and fixed to the inner surface of the lining substrate 2.

In the mounting structure of the side impact cushioning pad 1, the side impact cushioning pad 1 does not use any member other than the door lining for automobiles, and the side impact cushioning pad 1 is simply press-fitted into the rising plate 20 to line the lining. It can be stably attached and fixed to the inner surface of the substrate 2. Further, at the time of a side collision, the side impact cushioning pad 1 is deformed or crushed between itself and the door inner panel under the load of the occupant, so that the impact applied to the occupant can be alleviated. At this time, since the rising size of the rising plate 20 and the protruding piece 21 is smaller than that of the side impact cushioning pad 1, the side impact cushioning pad 1 is not affected by deformation or crushing of the side impact cushioning pad 1. Buffer measures can be taken.

Although the side impact cushioning pad 1 described above has a bottomed casing type, it is also possible to use a resin which is simply molded into a quadrangular cylindrical frame shape without providing a bottom portion. In the case of the tubular frame-shaped side impact cushioning pad 1, the rising plate 20 and the protruding piece 2
In addition to being fitted on the outside of the side impact cushioning pad 1, 1 can also be fitted on the inside of the side impact cushioning pad 1 by forming the hooking claw 21a of the protrusion piece 21 downward. Further, the projection piece 21 can be meshed with the upper side surface of the side collision cushioning pad 1 from the inside by forming the hooking claw 21a upward.

The rising plate 20, like the protruding piece 21, can be reinforced by forming ribs on the outside of each of the side faces 20a to 20e. Instead of forming the rising plate 20 into a continuous frame shape, each side surface 1 of the side impact cushioning pad 1
You may separate and form every 0-13. Also, both lower end sides 20
It is also possible to form the side impact cushioning pad 1 by receiving it on at least three side surfaces of the side impact cushioning pad 1 to receive and support the side impact cushioning pad 1 without providing d and 20e.

In order to mold the above-mentioned projection piece 21, a core for restricting the standing surface of the latching claw 21a is formed on the mold surface so as to project, and the punched hole 2d is formed on the plate surface of the lining substrate 2 as shown in FIG. It is good to have it occur in. In this mold structure, since it is not necessary to provide the slide mold part in the mold, not only the mold cost can be prevented from increasing, but also the claw-shaped undercut part can be eliminated.

The hole 2d can be located inside the door pocket 3 attached to the front side of the door lining substrate 2 so as not to be seen from the outside, as shown in FIG. Further, as shown in FIG. 5, the separate door pocket 3 is formed by projecting the welding pin 4 on the inner surface near the end and inserting the welding pin 4 into the receiving hole of the door lining substrate 2 to crush and deform the projecting end side. It can be attached and fixed to the door lining substrate 2. Instead of the welding pin 4, a tapping screw that is screwed in from the inner surface side of the door lining substrate 2 may be tightened and fixed.
