Abstract
Official abstract text for this publication.
An instrument panel beam is the instrument panel beam that is arranged in the width direction of an automobile, and includes: a large-diameter hollow tube having a hollow cylindrical shape; and a small-diameter hollow tube which is joined to the large-diameter hollow tube in an axial direction, has a diameter that is smaller than that of the large-diameter hollow tube, and has a hollow cylindrical shape. The small-diameter hollow tube includes two flat plates that extend in a longitudinal direction and two bends that are curved in a circumferential direction, and the flat plates and the bends are alternately arranged in the circumferential direction.
First claim
Opening claim text (preview).
The invention claimed is: 1. An instrument panel beam that extends in a width direction of an automobile, the instrument panel beam comprising: a large-diameter hollow tube having a hollow cylindrical shape; and a small-diameter hollow tube having a diameter that is smaller than that of the large-diameter hollow tube and having a hollow cylindrical shape, wherein the large-diameter hollow tube and the small-diameter hollow tube are joined to each other in an axial direction, the small-diameter hollow tube comprises at least two flat plates that extend in a longitudinal direction and at least two bends that are curved in a circumferential direction, the flat plates and the bends being alternately arranged in the circumferential direction, the large-diameter hollow tube comprises at least two flat plates that extend in a longitudinal direction and at least two bends that are curved in a circumferential direction, the flat plates and the bends being alternately arranged in the circumferential direction, and each flat plate of the small-diameter hollow tube has a width that is greater than that of each flat plate of the large-diameter hollow tube. 2. The instrument panel beam according to wherein the at least two bends of the large-diameter hollow tube have a curved surface shape that is convex outward in a radial direction. 3. The instrument panel beam according to claim 1 , wherein the at least two bends of the small-diameter hollow tube have a curved surface shape that is convex outward in a radial direction. 4. The instrument panel beam according to claim 1 , comprising a reduced diameter portion of which a diameter is reduced from one end to another end, wherein the one end of the reduced diameter portion is fixed to an end of the large-diameter hollow tube, and the other end is fixed to an end of the small-diameter hollow tube. 5. The instrument panel beam according to claim 1 , wherein a curvature radius of the bends of the large-diameter hollow tube is larger than a curvature radius of the bends of the small-diameter hollow tube. 6. A pair of brackets into which the instrument panel beam according to claim 1 is fit, the pair of brackets comprising: a first bracket comprising an opening into which the large-diameter hollow tube of the instrument panel beam is fit; and a second bracket comprising an opening into which the small-diameter hollow tube of the instrument panel beam is fit. 7. An instrument panel beam assembly comprising: the instrument panel beam according to claim 1 ; a first bracket comprising an opening into which the large-diameter hollow tube of the instrument panel beam is fit; and a second bracket comprising an opening into which the small-diameter hollow tube of the instrument panel beam is fit, wherein the instrument panel beam is fit into the first bracket and the second bracket.
