A device for moving a window glass for a vehicle, may include a glass holder disposed on a door panel for the vehicle and supporting the window glass, and a curved rail guiding vertical movement of the glass holder and curved to form a hinge shaft.

A vehicle door assembly includes a first molding, a second molding and an end cap. The first molding is configured to be installed to a first door component. The second molding is configured to be installed to a second door component. The first and second moldings at least partially define a vehicle window opening. The end cap supports an end of the first molding to an end of the second molding. The end cap has an extension extending across a gap at least partially defined by the first and second moldings to fill the gap.

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 system for reducing strain on a vehicle door comprises the vehicle door. The vehicle door comprises an inner panel and a division bar comprising a first portion and a second portion. The system further comprises a relief bracket configured to reduce strain on the inner panel when the vehicle door is closed. The relief bracket comprises a first portion coupled to the second portion of the division bar, a second portion coupled to the inner panel, and a relief portion extending between the first portion and the second portion.

A vehicle door structure that suppresses a situation in which the door window detaches from the above-mentioned guide rail includes a front guide rail that holds a door window while allowing a raising and lowering operation of the door window, and a guide rail support portion that fixes the front guide rail to a door inner panel, wherein the guide rail support portion includes a first section that is fixed to a front face portion of a door inner panel, a second section that extends rearward from a vehicle-width-direction inner side of the first section, and a third section that is provided at a rear end portion of the second section and that is fixed to the front guide rail, and the second section and the third section are configured to be supported in a cantilever manner with respect to the first section.

A multi-component door assembly for a vehicle includes a lower door portion rotatably coupled to a body of the vehicle and including at least one receiving aperture defined therein, and an upper door portion selectively removable from the lower door portion and including at least one post configured to be received within the at least one receiving aperture for removably coupling the upper door portion to the lower door portion. At least one trim cap is configured to selectively cover and conceal the at least one receiving aperture.

A vehicle described in the present specification is configured such that a door includes an outer panel, a door trim, window glass configured to be manually raised and lowered, a belt molding, and a knob. The window glass is supported movably between an upper limit position at which the window glass closes an opening of a window frame and a lower limit position at which the window glass opens the opening of the window frame. The knob is configured to be gripped by a user who operates the window glass. The door trim includes a recess configured to face the knob and form a space when the window glass is placed at the lower limit position, the space being formed to receive a hand of the user, the hand gripping the knob.

A vehicle door includes a window frame and a lower surface portion formed jointly with the window frame in one piece from a hot formed and press hardened sheet metal plate which is made of a steel alloy which includes, in weight-%: Carbon 0.33-0.38, Silicon 0.2-0.7, Manganese 0.7-1.2, Phosphorus max. 0.03, Sulfur max. 0.02, Boron 0.002-0.005, Chromium 0.6-1.0, Copper max. 0.12, Nitrogen max. 0.005, Titanium 0.015-0.025, Nickel 1.5-2.0, Molybdenum 0.2-0.6, Tin max. 0.04, and as optional components Aluminum 0.006-0.08, Niobium 0.02-0.05, with a balance being iron and incidental impurities. At least the lower surface portion has a Brinell hardness of 500 to 600 HB and a yield strength of 1,200 to 1,450 MPa, wherein the lower surface portion and/or the window frame has a wall thickness of at least 6 mm.

A vehicle door assembly includes a first molding, a second molding and an end cap. The first molding is configured to be installed to a first door component. The second molding is configured to be installed to a second door component. The first and second moldings at least partially define a vehicle window opening. The end cap supports an end of the first molding to an end of the second molding. The end cap has an extension extending across a gap at least partially defined by the first and second moldings to fill the gap.

A multi-component door assembly for a vehicle includes a lower door portion rotatably coupled to a body of the vehicle and including at least one receiving aperture defined therein, and an upper door portion selectively removable from the lower door portion and including at least one post configured to be received within the at least one receiving aperture for removably coupling the upper door portion to the lower door portion. At least one trim cap is configured to selectively cover and conceal the at least one receiving aperture.
