Method for producing a reinforcement beam for a vehicle, comprising at least one weak zone arranged in such a way that the bending resistance of the beam is less in said weak zone than in the rest of the beam, characterized in that it comprises, in order, a step (A) of extruding a profile part, a step (B) of cutting the profile part so as to obtain at least one profile segment, a step (C) of locally deforming the segment of the profile part in order to create the weak zone or zones.

A door beam including an aluminum alloy extrusion extended in a longitudinal direction and having a pair of webs and a pair of flanges to be positioned on an inside and an outside in a vehicle width direction. The pair of webs connect the pair of flanges at joint portions of each of the pair of webs such that the pair of webs and the pair of flanges form a closed cross section in a direction perpendicular to the longitudinal direction, and each of the pair of webs has a welded portion in a vicinity of a neutral axis passing through a centroid of the closed cross section and parallel to the pair of flanges.

A vehicle side section structure capable of stabilizing the deployment behavior of an airbag that inflates and deploys from a side door toward a vehicle width direction outer side is obtained. An impact beam is attached to a door inner panel. The impact beam includes a support portion that supports an inflator and that includes a side-wall portion disposed at the vehicle width direction inner side of the inflator. Accordingly, reaction force from the deployment of the airbag is able to be supported by the support portion of the impact beam when the airbag inflates and deploys.

A main body (2) has door attaching portions respectively formed on both end sides of a long longitudinal direction thereof and a bending deformation generation portion (3) disposed between the door attaching portions, and the bending deformation generation portion (3) has a groove bottom portion (4), two edge line portions (5a, 5b), two vertical wall portions (6a, 6b), two curved portions (7a, 7b), and two flanges (8a, 8b). There is provided a bead (13) which is formed toward the longitudinal direction of the main body (2) in a part of the groove bottom portion (4) in a manner to project in a shape having a curved surface toward the outside of a cross-sectional shape of the bending deformation generation portion (3) so as to oppose an impact load acting on a door impact beam (1).

A method includes molding an outer impact beam made of carbon fiber reinforced plastics (CFRP) and separately molding an inner impact beam made of CFRP. The outer impact beam and the inner impact beam are coupled to each other to form an impact beam and the impact beam is coupled to an inner panel of a vehicle door.

To make it possible to make impact absorption at the time of a collision even when there is no sufficient space.

[Solution] An impact absorption member according to the present invention includes: a member that is placed adjacent to an exterior material 110 of an automobile and in which a height in a direction orthogonal to the exterior material is larger than a width in a direction along the exterior material in a cross section orthogonal to an extending direction of the member. By this configuration, a first member 122 and a second member 124 are arranged so as to extend in different directions and be adjacent to the exterior material 110 of an automobile, and therefore impact absorption at the time of a collision can be made even when there is no sufficient space.

A door beam for a vehicle may include a beam portion having a rod shape which extends along a longitudinal direction of a vehicle body, a front mounting portion disposed at a front end portion of the beam portion to mount the front end portion of the beam portion to the door, and a rear mounting portion disposed at a rear end portion of the beam portion to mount the rear end portion of the beam portion to the door.

A door beam includes an aluminum alloy extrusion body extended in a longitudinal direction and having a pair of webs and a pair of flanges to be positioned on an inner side and an outer side in a width direction of a vehicle body. The pair of webs connect the pair of flanges at joint portions of each of the pair of webs such that the pair of webs and the pair of flanges form a closed cross section in a direction perpendicular to the longitudinal direction, and the pair of webs do not have a welded portion.

A mounting structure for mounting an interior component to a door trim body includes: a rear locking protrusion including a first portion protruding from a back surface of the interior component and a second portion extending from a distal end of the first portion toward a front of a vehicle; a rear mounting hole in a rear edge section of the door trim body and opposed to the rear locking protrusion; a locking protrusion protruding from the back surface toward the door trim body and is disposed closer to a front of the vehicle relative to the rear locking protrusion; and a mounting hole in a section of the door trim body at a position closer to the front relative to the rear mounting hole and opposed to the locking protrusion. The second portion of rear locking protrusion is locked to a hole edge of the rear mounting hole.

An impact beam structure of a CFRP door for a vehicle is disclosed. A outer impact beam and an inner impact beam are separately molded and then coupled to each other such that an impact beam is formed. The impact beam is coupled to an inner panel of the CFRP door for the vehicle.
