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.

Vertical frame portions provided at both side portions of a door frame are a light-metal casting, plural connecting frames, which are a light-meal hollow extrusion molding, connect the vertical frame portions, the vertical frame portions are provided with protrusion portions which engage with inward connecting frames in a longitudinal direction, plural attachment portions which attach the outward connecting frames and the vertical frame portion are provided at different points in the longitudinal direction, and an outward connecting frame is provided with an upper rib which engages with an engagement recess portion provided at an upper portion of a door outer panel formed in a non-planar shape.

A vehicle side portion structure that includes: a pair of rockers that, at vehicle side portions, respectively extend along a vehicle longitudinal direction at both outer sides in a vehicle transverse direction of a floor panel that is a floor portion of a vehicle cabin interior, first impact absorbing portions that form closed cross-sectional structures and that, at a time of a side collision of a vehicle, plastically deform and absorb collision energy being provided at interiors of the pair of rockers; and side doors that open and close door opening portions of the vehicle side portions, second impact absorbing portions, which form closed cross-sectional structures and, at the time of a side collision of the vehicle, plastically deform and absorb collision energy, being provided at lower portions of interiors of the side doors.

A vehicle side portion structure includes a front side door and a rear side door of a vehicle that does not have a center pillar. A lock member is disposed at a vertical direction lower portion of one side door of the front side door and the rear side door. When the one side door is closed, the lock member engages with the other side door to lock the one side door. A reinforcement member is provided inside the one side door at the vertical direction lower portion. A part of the reinforcement member is disposed on an upper side of the lock member so that the lock member is surrounded by the reinforcement member and the peripheral edge portion of the one side door as seen in a side view of the vehicle.

A seat belt apparatus provided in a front door of a vehicle, comprises a retractor provided in the front door and configured to retract a webbing for constraining an occupant so as to be pulled out, a belt anchor provided in the front door and attached with one end of the webbing, and a latch configured to engage the front door to a vehicle body. The latch is provided between the retractor and the belt anchor in a longitudinal direction of the vehicle body.

A vehicle body side structure includes: a side sill extending in a longitudinal direction of a vehicle at a side bottom of the vehicle and having a recess sagging inward in a width direction of the vehicle; a door being hollow, having a door bottom portion disposed so as to overlap the side sill when seen from a side, and being arranged at an outer side of the side sill in the width direction; and a force transferring member having a projection protruding inward in the width direction, being disposed in a hollow interior of the door bottom portion, and being configured to transfer force acting inward in the width direction to the side sill.

A vehicle side portion structure including: a rocker that extends in a vehicle longitudinal direction at a vehicle transverse direction outer side of a vehicle body lower portion; a sliding door that slides in the vehicle longitudinal direction, includes a door inner panel, which is connected to the rocker by a door hinge slidable in the vehicle longitudinal direction and which has a mounted-to portion that is lined up in a vehicle transverse direction with the rocker, and includes a door outer panel that is disposed further toward a vehicle transverse direction outer side than the door inner panel; and a load transmitting member that is mounted to the mounted-to portion and transmits a collision load, which is input to the door outer panel from a vehicle side, to a region of the rocker that is different from a region to which the door hinge is connected.

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 motor vehicle door and a method for producing the motor vehicle door is disclosed having a frame plate coupled to reinforcement components and at least half of all of the reinforcement components are produced as extruded profiles which are subsequently press-formed three-dimensionally. The extruded profiles have different wall thicknesses.

A vehicle side portion structure including: a rocker that extends in a vehicle longitudinal direction at a vehicle transverse direction outer side of a vehicle body lower portion; a sliding door that slides in the vehicle longitudinal direction, includes a door inner panel, which is connected to the rocker by a door hinge slidable in the vehicle longitudinal direction and which has a mounted-to portion that is lined up in a vehicle transverse direction with the rocker, and includes a door outer panel that is disposed further toward a vehicle transverse direction outer side than the door inner panel; and a load transmitting member that is mounted to the mounted-to portion and transmits a collision load, which is input to the door outer panel from a vehicle side, to a region of the rocker that is different from a region to which the door hinge is connected.
