A vehicle door according to an exemplary embodiment enhances coupling strength through structural coupling by molding a window frame of a door module assembled between a door trim and the door panel with a separate aluminum injection product, and insert-injection molding a coupling portion of the window frame to a module body, and a groove is formed along the coupling portion of the window frame coupled to the module body to easily distinguish respective parts and serve to carry out sealing in injection molding.

A customer-specific vehicle door leaf, in particular a customer-specific rail-vehicle door leaf, preferably an inwardly opening customer-specific vehicle door leaf for an entry door. The door leaf includes a panel and a general vehicle door leaf, wherein the general vehicle door leaf preferably has a supporting vehicle door leaf frame, and the general vehicle door leaf itself is pressure-tight and/or waterproof, and the panel is provided on the vehicle door leaf frame.

A door assembly for a motor vehicle comprised of an outer door panel and an inner door panel interconnected to define a door panel structure having an internal door cavity. A collapsible carrier module is configured to be oriented in a collapsed arrangement to facilitate installation into the door cavity through an opening in the inner door panel. The collapsible carrier module can be moved from its collapsed arrangement into an expanded arrangement upon installation within the door cavity to facilitate subsequent mounting to the door panel structure. The collapsible carrier module includes a barrier configured to close off the opening in the inner panel.

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 frame includes an upper frame having a first end face at a longitudinal end, and a lower external face; and a lower member of a plate form bonded to the upper frame. The lower member includes a second end face facing the first end face, a projection projecting from the second end face in a longitudinal direction below the upper frame, and a third end face located at an upper end of the projection, extending in the longitudinal direction, and facing a lower side of the external face of the upper frame.

A vehicle door includes a window area and a hollow door body underneath the window area. A web divides the window area into a front and rear window, and extends into the door body. At least one of the windows has a movable pane, one edge of which engages into a groove of the web. A web holder is anchored on a wall of the door body, and plug connected with a lower end of the web in the longitudinal direction of the web.

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.

Described herein is a structure of a motor-vehicle door including a multi-thickness metal sheet pressed and shaped to define: a hinge area configured for fastening one or more hinges for connection to the body of a motor vehicle; a panel area configured for receiving an upholstery-trim element for the door; and a frame area configured for receiving a window of the door. The above multi-thickness metal sheet has a first thickness in said hinge area, a second thickness in said panel area, and a third thickness in said frame area.
