A vehicle includes a vehicle body and a vehicle door connected to the vehicle body. The vehicle door includes an interior trim panel including an upper board and an ornament member that is connected to an interior surface of the upper board. The ornament member has a front edge, a rear edge and side edges that extend from the front edge to the rear edge. The ornament member includes an interference member that extends outwardly from at least one of the front edge, the rear edge and the side edges and extends under the upper board to interface with the upper board during a side impact event.

A vehicle door includes a door box with first and second walls and a second wall and a window frame module, in which a window frame, a first window shaft reinforcement and a second window shaft reinforcement are connected into a structural unit. The first window shaft reinforcement features a groove that accommodates an upper edge of the first wall. An upper edge of the second wall is covered by the second window shaft reinforcement.

A convertible door assembly includes (a) an upper door section, defining a window opening, (b) a lower door section, (c) a releasable locking feature, retaining the upper door section to the lower door section, and (d) a window. The window is displaceable between a raised position, closing the window opening and a lowered position, concealed within an internal door cavity formed in the upper door section and the lower door section.

A vehicle may include a vehicle body, a door, a window frame, a window panel, a lower support and an anti-vibration member. The window panel may be provided in the window frame, configured to be manually raised and lowered, and supported to movable between an upper limit position where the window panel closes an opening of the window frame and a lower limit position where the window panel opens the opening of the window frame. The lower support may include a groove. The groove may be configured to receive a lower edge of the window panel when the window panel is located at the lower limit position. The anti-vibration member may have viscoelasticity, disposed in the groove of the lower support, and configured to hold the window panel from both sides of the window panel.

A convertible door assembly includes (a) an upper door section, defining a window opening, (b) a lower door section, (c) a releasable locking feature, retaining the upper door section to the lower door section, and (d) a window. The window is displaceable between a raised position, closing the window opening and a lowered position, concealed within an internal door cavity formed in the upper door section and the lower door section.

A front door frame includes an upper sash and a lower member. The upper sash has a first end face being one flat, longitudinal end crossing a longitudinal direction, and a lower outer face. The lower member includes a second end face that abuts on the first end face, and a projection that projects along the outer face in a direction where the second end face faces, to support the upper sash. The first end face abuts on the second end face but does not abut on a tip of the projection.

A convertible door assembly includes (a) an upper door section, defining a window opening, (b) a lower door section, (c) a releasable locking feature, retaining the upper door section to the lower door section, and (d) a window. The window is displaceable between a raised position, closing the window opening and a lowered position, concealed within an internal door cavity formed in the upper door section and the lower door section.

A door structure for a vehicle that includes a door outer panel; a door inner panel including a first join-receiving portion protruding to the vehicle upper side relative to a vehicle upper side end of the door outer panel, and a second join-receiving portion protruding to the vehicle upper side relative to the vehicle upper side end of the door outer panel and being disposed to be spaced apart from the first join-receiving portion in a vehicle horizontal direction along the vehicle upper side end of the door outer panel; and a frame portion formed using a material with a different thermal expansion coefficient from the door inner panel, the frame portion including a first joining portion joined to the first join-receiving portion by a rivet and a second joining portion joined to the second join-receiving portion by a rivet.
