Abstract

Provided is a damping member for a vehicle having excellent efficiency of input energy absorption. A damping pad serving as a damping member for a vehicle includes a base plate portion having a flat plate shape, a vertical wall arranged at a rim of the base plate portion in a flange-like manner, a plurality of ribs arranged in parallel as rising from the base plate portion, each of the ribs connected to a vertical wall as extending in a direction intersecting with the vertical wall, and a fragile section arranged between adjacent two of the ribs. The fragile section includes a groove formed at the vertical wall and a slit formed at the base plate portion.

First claim

The invention claimed is:

1. A damping member for a vehicle arranged at a back face of a trim member attached to cover a vehicle body panel, and configured to absorb input energy of an input load and deformed by crush, the damping member for a vehicle comprising:
a base plate portion having a flat plate shape;
a vertical wall arranged at a rim of the base plate portion in a flange-like manner;
a plurality of ribs arranged in parallel as rising from the base plate portion, each of the ribs connected to the vertical wall as extending in a direction intersecting with the vertical wall; and
a fragile section having strength of the vertical wall locally reduced, the fragile section arranged between adjacent two of the ribs, the fragile section including,
a groove formed at the vertical wall, and
a slit formed at the base plate portion,

wherein the groove includes,
a first groove formed at a leading end part of the vertical wall, the first groove extending in a thickness direction of the vertical wall, and
a second groove communicating with the first groove, the second groove extending in a height direction of the vertical wall, and

the slit has an opening shape elongated along an extending direction of the vertical wall, the slit being in contact with the vertical wall.

2. The damping member for a vehicle according to claim 1 ,
wherein the base plate portion has an approximately rectangular shape having longer side in a vehicle lateral direction,
the vertical wall is arranged at the entire rim of the base plate portion, and
the vertical wall has partially cut out portions at four corners of the base plate portion.

3. A damping member for a vehicle arranged at a back face of a trim member attached to cover a vehicle body panel, and configured to absorb input energy of an input load and deformed by crush, the damping member for a vehicle comprising:
a base plate portion having a flat plate shape;
a vertical wall arranged at a rim of the base plate portion in a flange-like manner;
a plurality of ribs arranged in parallel as rising from the base plate portion, each of the ribs connected to the vertical wall as extending in a direction intersecting with the vertical wall; and
a fragile section having strength of the vertical wall locally reduced, the fragile section arranged between adjacent two of the ribs, the fragile section including,
a groove formed at the vertical wall, and
a slit formed at the base plate portion,

wherein the base plate portion has an approximately rectangular shape having longer side in a vehicle lateral direction,
the vertical wall is arranged at the entire rim of the base plate portion, and
the vertical wall has partially cut out portions at four corners of the base plate portion.
