Abstract

A vehicle door impact beam disposed between first and second door panels includes: a first grooved portion configured to include a bottom wall portion extending along the first door panel in a predetermined direction, and side wall portions; a second grooved portion disposed a predetermined gap away from the first grooved portion in the width direction, and configured to include a bottom wall portion and side wall portions respectively connected to both end portions of the bottom wall portion in the width direction; and a connection wall portion configured to connect one side wall portion, which is one of the side wall portions of the first grooved portion and positioned on a second grooved portion side, to one side wall portion which is one of the side wall portions of the second grooved portion and positioned on a first grooved portion side.

First claim

What is claimed is:

1. A vehicle door impact beam that is disposed between a first door panel and a second door panel of a door of a vehicle, the impact beam comprising:
a first grooved portion configured to include a bottom wall portion which extends along the first door panel in a predetermined direction, and a pair of side wall portions which are respectively connected to both end portions of the bottom wall portion in a width direction, and extend in the predetermined direction, and configured to open toward a second door panel side;
a second grooved portion that is disposed a predetermined gap away from the first grooved portion in the width direction, is configured to include a bottom wall portion which extends along the first door panel in the predetermined direction, and a pair of side wall portions which are respectively connected to both end portions of the bottom wall portion in the width direction, and extend in the predetermined direction, and is configured to open toward the second door panel; and
a connection wall portion configured to connect one side wall portion, which is one of the pair of side wall portions of the first grooved portion and is positioned on a second grooved portion side, to one side wall portion which is one of the pair of side wall portions of the second grooved portion and is positioned on a first grooved portion side, and configured to extend along the second door panel in the predetermined direction,
wherein the first grooved portion includes a protrusion that protrudes toward an inside of the first grooved portion from a second door panel side end portion of the other side wall portion of the pair of side wall portions, and that extends in the predetermined direction,
wherein the second grooved portion includes a protrusion that protrudes toward an inside of the second grooved portion from a second door panel side end portion of the other side wall portion of the pair of side wall portions, and that extends in the predetermined direction,
wherein the first grooved portion, the second grooved portion, and the connection wall portion are formed integrally with each other via extrusion forming,
wherein the first grooved portion includes a protrusion that protrudes toward an outside of the first grooved portion from another second door panel side end portion of the other side wall portion of the pair of side wall portions, and that extends in the predetermined direction, and
wherein the second grooved portion includes a protrusion that protrudes toward an outside of the second grooved portion from another second door panel side end portion of the other side wall portion of the pair of side wall portions, and that extends in the predetermined direction.

2. The vehicle door impact beam according to claim 1 ,
wherein the protrusion formed towards the inside of the first grooved portion has the same protrusion height as that of the protrusion formed towards the outside of the first grooved portion, and
wherein the protrusion formed towards the inside of the second grooved portion has the same protrusion height as that of the protrusion formed towards the outside of the second grooved portion.

3. The vehicle door impact beam according to claim 1 ,
wherein the bottom wall portion of the first grooved portion is formed to have a thickness larger than that of the side wall portions of the first grooved portion,
wherein the bottom wall portion of the second grooved portion is formed to have a thickness larger than that of the side wall portions of the second grooved portion, and
wherein the connection wall portion is formed to have a thickness larger than those of the respective side wall portions of the first grooved portion and the second grooved portion.

4. The vehicle door impact beam according to claim 1 ,
wherein respective end portions of the first grooved portion and the second grooved portion in a longitudinal direction have groove depths larger than those of respective central portions of the first grooved portion and the second grooved portion in the longitudinal direction.

5. The vehicle door impact beam according to claim 4 ,
wherein a first door panel side portion of the end portion of the first grooved portion is positioned higher than a second door panel side portion of the end portion of the first grooved portion, and
wherein a first door panel side portion of the end portion of the second grooved portion is positioned lower than a second door panel side portion of the end portion of the second grooved portion.
