In an embodiment, a side door for a vehicle, includes: a structure comprising a shell comprising a shell support beam positioned across a main body portion of the shell, wherein the shell support beam comprises substantially unidirectional fiber strip sections; wherein the shell comprise a inner shell and a outer shell; and wherein the side door has a score of at least 4 points in a side impact test conducted according to European New Car Assessment Protocol (Euro NCAP) Side Impact Testing Protocol Version 5.2 (November 2011).

The disclosure provides a vehicle side structure. The vehicle side structure is for being mounted near a door, and includes: an electric motor disposed inside the door to drive a door glass up and down; a fitting member, fitting the door and a vehicle body; and a connecting member, connecting the fitting member and the electric motor.

A vehicle door structure has: a door inner panel that is made of resin and that, together with a door outer panel, structures a door main body portion having a substantially closed cross-sectional shape; a beam having a main body portion, that extends in a door longitudinal direction, and an extended portion that is made of metal and is provided in continuation with a length direction end portion of the main body portion, the beam being disposed within the closed cross-section of the door main body portion; and a bent portion that is bendingly formed at the extended portion, and that, as seen in plan view, is disposed further toward a door thickness direction outer side than the frame main body portion.

A motor vehicle includes a body that has a doorway. A side door is moveably held on the doorway and displaceable between a closed position and an open position. The side door has an inner door part, a reinforcement element, and a planking element. The reinforcement element has an upper deformation region and a lower deformation region. An impact damper that is a foam part is disposed inside the side door between the reinforcement element and the inner door part. The impact damper extends over at least a partial length of the reinforcement element and substantially completely fills a cavity delimited between the reinforcement element and the inner door part.

A side door structure includes an inner panel, an outer panel, a drain hole, and an impact absorbing member. The inner panel covers a vehicle-widthwise outer side of a side sill extending in a front-rear direction of a vehicle body of a vehicle. The outer panel is disposed at a position facing the inner panel and joined, at an edge part of the outer panel, to the inner panel to constitute a side door of the vehicle together with the inner panel. The drain hole is provided in a lower end part of the inner panel. The drain hole is designed to rainwater entering an internal space of the side door from an outside of the vehicle. The impact absorbing member is disposed on a vehicle-widthwise inner side of the inner panel. The impact absorbing member extends in the front-rear direction at a position facing the side sill.

A side door structure includes an inner panel, an outer panel, a drain hole, an impact absorbing member, and a fixing member. The inner panel covers a vehicle-widthwise outer side of a side sill. The outer panel faces the inner panel and constitutes a side door together with the inner panel. The drain hole is provided in a lower end part of the inner panel and formed to drain rainwater entering the inside of the side door. The impact absorbing member is disposed inside the side door and extends in a front-rear direction of a vehicle body. The fixing member fixes the impact absorbing member to the inner panel at a position higher than a position facing the side sill. The fixing member is set to have a fixing strength at which the impact absorbing member is releasable upon input of an impact load of a predetermined load or more.

A vehicle door assembly is constructed with improved rigidity, which ensures sufficient rigidity even without the formation of pillars in a vehicle. The door assembly includes a front door and a rear door, which each include an outer panel and an inner panel coupled to the outer panel. The door assembly further includes an outer member having upper and lower ends coupled to upper and lower ends of the outer panel, respectively, and spaced apart from the outer panel between the upper and lower ends. The door assembly also includes an inner member having upper and lower ends coupled to upper and lower ends of the inner panel, respectively, and spaced apart from the inner panel between the upper and lower ends. The outer member and the inner member are coupled to each other along the height direction of the vehicle. This forms a closed cross-section between the outer member and the inner member.
