There is provided an automotive vehicle which comprises a side door, impact bars provided at the side door, a side inner panel, a first reinforcing member provided to extend along a rear side of a peripheral portion of an entrance portion and joined to an outside of the side inner panel so as to form a first closed cross section together with the side inner panel, and second reinforcing members joined to an outside of the first reinforcing member so as to form second closed cross sections together with the first reinforcing member, the second reinforcing members being configured to overlap with the impact bars, in a side view, when the side door closes the entrance portion.

A door beam includes an outer flange, an inner flange, and a pair of webs connecting the outer flange and the inner flange. The outer flange, the inner flange, and the pair of webs define a closed cross-sectional portion. The outer flange includes an outer central portion constituting the closed cross-sectional portion, and outer protruding portions protruding outward from the closed cross-sectional portion. The inner flange is formed with an attachment press working portion having been subjected to press working so as to serve as an attachment portion with respect to the inner panel at both end portions in the longitudinal direction. The outer protruding portion is formed with a mastic press working portion having been subjected to press working so as to serve as an attachment portion with respect to the outer panel.

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 vehicle door structure includes a reinforcing member that is extended along a side sill on an inner door panel side of a lower portion of an outer door panel. The reinforcing member has a first side surface that faces the side sill in the vehicle width direction, and a second side surface that extends from the first side surface to the outer door panel, and the first side surface and the second side surface are joined to the inner door panel.

A vehicle door including a door inner and a reinforcing beam fixed to the door inner. The reinforcing beam includes a first layer and a second layer bonded to each other. The first layer includes a polymer and fibers impregnated in the polymer and extending continuously across the polymer of the first layer. The first layer extends along an axis and has first and second ends spaced from each other on the axis. The second layer includes a polymer and fibers impregnated in the polymer and extending continuously across the polymer of the second layer. The second layer has first and second ends spaced from each other on the axis. The first and second ends of the second layer are each disposed between the first and second ends of the first layer along the axis.

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.

A door for a motor vehicle that includes at least one thermoformed panel part, a supporting structure to support the panel part, and a holder fastened to the panel part. The holder is to engage in a shaped portion of the supporting structure or in a support element fastened to the supporting structure, so that the panel part may slide on the shaped portion and/or the support element in a direction perpendicular to the direction of engagement.

A strengthening member for a motor vehicle and a vehicle including a strengthening member are provided. The strengthening member can have a cross-section that has twenty-four corners and includes sides and corners creating sixteen internal angles and eight external angles. The vehicle may include a strengthening member that has twenty-four corners and includes sides and corners creating sixteen internal angles and eight external angles.

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, characterised 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 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.
