Abstract

The purpose of the present invention is to obtain a vehicle body component such that problems relating to conventionally proposed technology can be solved, thereby preventing increases in the number of components or manufacturing steps for reinforcement, for example. A bumper reinforce ( 10 ) includes a first component ( 11 ) and a second component ( 21 ) that are formed from channel steel with approximately U-shaped lateral cross section, and is configured by connecting the ends of the components ( 11, 21 ). Connecting portions ( 13, 23 ) of the first component ( 11 ) and the second component ( 21 ) respectively have slits ( 31, 41 ) along a direction in which the components ( 11, 21 ) are arranged. The components ( 11, 21 ) are connected with the components ( 11, 21 ) overlapping each other in a staggered manner on both upper and lower sides across the slits ( 31, 41 ).

First claim

1 . A vehicle body component comprising:
a first component and a second component which are formed of a plate material, and configured to extend in a juxtaposition direction in which the components are arranged, by connecting end portions of the components, wherein
the connection-side end portion of the first component has a slit which opens at its end, and
the connection-side end portion of the first component and the connection-side end portion of the second component overlap each other in a staggered manner on opposite sides across the slit.

2 . A vehicle body component according to claim 1 , wherein one side of the opposite sides across the slit is retracted inward in the connection-side end portion of the first component and a step is provided between the one side and the other side across the slit.

3 . A vehicle body component according to claim 1 , wherein the slit extends in the juxtaposition direction.

4 . A vehicle body component according to claim 3 , wherein the connection-side end portion of the second component has a slit which opens at its end and extends along the juxtaposition direction; the slit overlaps the slit of the first component; and the side which is retracted inward is the opposite to the first component and a step is provided between the side and the other side across the slit of the second component.

5 . A vehicle body component according to claim 4 , wherein the first component and the second component have the same plate thickness, and the dimension of the steps are substantially equal to the plate thickness.

6 . A vehicle body component according to claim 4 , wherein the slits provided in the first component and the second component are provided at respective central portions with respect to a direction substantially orthogonal to the juxtaposition direction.

7 . A vehicle body component according to claim 4 , wherein in each of the connection-side end portions of the first component and the second component,
one of plate portions located on the opposite sides across the slit is a first flat plate portion flush with a plate portion, and the other plate portion is a second flat plate portion which forms the step in cooperation with the first flat plate portion as a result of subjection to bending while being held in parallel with the first flat plate portion.

8 . A vehicle body component according to claim 7 , wherein the second flat plate portion of the first component and the second flat plate portion of the second component are in contact with each other at their edges.

9 . A vehicle body component according to claim 7 , wherein
each of the first component and the second component has a channel-shaped cross section and has a bottom plate portion along a direction substantially orthogonal to the juxtaposition direction and a pair of side plate portions extending sideward from opposite ends in the substantially orthogonal direction of the bottom plate portion; in each of the connection-side end portions of the first component and the second component, the slit, the first flat plate portion, and the second flat plate portion are provided at the bottom plate portion; and of a pair of the side plate portions, the side plate portion connected to the second flat plate portion is subjected to bending in such a manner as to be disposed at a position shifted toward the other side plate portion.
