VEHICLE DOOR STRUCTURE

摘要

The frontal crash load is transmitted from a front pillar to a center pillar in a reliable manner so that a bending moment caused by the frontal crash load is favorably supported, and the deformation of the door is avoided. A beam member attached to an inner panel includes a S shaped cross section member. An upper channel section of the S shaped cross section member extends along the lower edge of a window opening, and a lower channel section extends adjacent to and in parallel to the lower edge of a window opening in a rear part of the door and is offset toward a lower part of the vehicle body in a rear part of the door, with a front end being located at a same elevation as an upper door hinge.

主权项

1. A vehicle door structure comprising:
an outer panel disposed on an outboard side; an inner panel disposed on an inboard side; and a beam member attached to the inner panel so as to extend in a fore-and-aft direction of a vehicle body, wherein: a cross section of the beam member comprises an S-shaped cross section part; the S-shaped cross section part is formed by a pair of channel sections each having a C-shaped cross section with a convex side thereof facing sideways, the two channel sections being connected one above the other in a mutually laterally reversed configuration; and at least one access hole is formed in a part of a vertically extending portion of the beam member that is vertically enlarged than another part of the vertically extending portion adjacent thereto in the fore-and-aft direction.
