Problems solved by technology

However, as the top plate grows, the center of the top plate becomes less rigid (therefore, the size of the top plate is limited to approximately 100mm in length and 100mm in width)
In addition, since an initial load is generated on the device and start absorbing collision energy only when the peripheral wall contacts the door trim, when a side collision occurs and the collision energy is generated, the collision energy is unabsorbable

no. 1 approach

[0031] The following will refer to Figure 1 to Figure 10 The first embodiment according to the present invention will be described in detail. like figure 1 As shown, the door trim panel 2 in this embodiment includes a door storage bag 21 , an armrest 22 , an inner handle 23 and the like. like figure 2 As shown, the door trim panel 2 is fixed on the interior side of the door panel 3 . The door panel 3 includes an inner door panel 31 provided on the inner side of the vehicle compartment and an outer door panel 32 provided on the outer side of the vehicle compartment.

[0032] The resin collision energy absorber 1 is an example of a resin collision energy absorber for absorbing side collision energy. If the door trim 2 has a surface close to the outside of the vehicle compartment, the resin collision energy absorbing device 1 is installed on the surface of the door trim 2 close to the outside of the vehicle compartment. In addition, "outside of the compartment and inside o...

no. 2 approach

[0051] Refer to the attached Figures 11 to 13 , the second embodiment of the present invention will be described. Unlike the resin collision energy absorbing device 1 , the resin collision energy absorbing device 4 in this embodiment further includes a restricting portion 41 . The restricting portion 41 is formed by connecting the outer walls 12 extending from the outer edge of the top plate 13 in an L-shape. In this embodiment, the same configurations as those in the first embodiment are assigned the same reference numerals, and descriptions of overlapping configurations, operations, and effects are omitted here.

[0052] Each corner portion 13A of the top plate 13 is connected to a restricting portion 41 . Therefore, in the event of a side collision, even if one corner 13A of the top plate 13 is impacted, the corner 13A of the top plate 13 can be prevented from being bent and deformed, so that the impact can be transmitted to the cross rib 11 . Figure 12 The dotted line...

Embodiment approach

[0054] The present invention is not limited to the embodiments described above with reference to the accompanying drawings, and the following embodiments are all included within the technical scope of the present invention, for example:

[0055] (1) In the above-described embodiment, the resin collision energy absorbing device 1 is mounted on the flat surface of the door trim 2 . According to the present invention, the resin collision energy absorbing device 1 can also be installed on the uneven part of the door trim 2 and arranged across the uneven surface. Alternatively, the resin collision energy absorbing device 1 may also be provided on an inclined surface or a curved surface on the door trim 2 .

[0056] (2) In the above-described embodiment, the opposite sides 11C of the cross ribs 11 are connected to the contact sides 12A of the respective outer walls 12 . According to the present invention, the opposite side 11C of the cross rib 11 may also be connected to a part of ...

Abstract

A resinous impact-energy absorber 1 includes a cross rib 11 that includes four ribs 11A and a connected portion 11B. The four ribs 11A are connected with each other in a single cross shape by the connected portion 11B. Each of the ribs 11A has an opposed edge 11C and a side edge. The opposed edge has a distance S1 from the door trim 2. The resinous impact-energy absorber also includes one outer wall 12 connected with one of the side edges of the ribs. The at least one outer wall 12 has a contact edge 12A capable of making contact with an outside surface of the door trim. The resinous impact-energy absorber also includes at least one seating face 14 for securing the cross rib to the outside surface of the door trim via the at least one outer wall.

Description

technical field [0001] The invention relates to a resin collision energy absorbing device, which is installed on the outer surface of a door trim relative to a vehicle compartment and is used for absorbing side collision energy. Background technique [0002] Various resin collision energy absorbers for absorbing side collision energy are known. The door trim panel has a surface close to the outside of the vehicle compartment, and the resin collision energy absorbing device is installed on the surface of the door trim panel close to the outside of the vehicle compartment. In Japanese Patent Laid-Open Publication No. Hei 8-142234, there is disclosed a resin collision energy absorbing device comprising a bottom plate and a plurality of ribs. The plurality of ribs protrudes from a base plate mounted on a surface of the door trim on the outside of the vehicle compartment and forms a lattice shape. On the other hand, in Japanese Invention Patent Laid-Open Publication No. 2007-55...
