A vehicle window system includes a vehicle door that has a window region. The system includes a fixed window having an exterior surface and an interior surface, a division bar, and a movable window. The fixed window is arranged in a first portion of the window region, and the division bar is arranged along a first region of the interior surface. The movable window is arranged in a second portion of the window region and is configured to close against the division bar. The division bar is not directly visible from outside of the vehicle door when viewed at an elevation of the fixed window. To illustrate, the movable window can be configured to move vertically within the first portion of the window region and the fixed window arranged at the top of the window region and the division bar is arranged substantially horizontally along the interior surface.

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 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 connecting device for coupling first and second members includes a body having a first leg and a second leg integrally connected to the first leg. The first leg and the second leg are oriented at an angle with respect to each other. A rigid material core extends through both the first leg and the second leg, the core including a first core member integrally connected to a second core member. The first core member is angularly oriented with respect to the second core member such that the core defines a geometric shape. A resilient material sleeve commonly covers the core of both the first leg and the second leg. The first leg is frictionally received in a first member and the second leg is frictionally received in a second member to couple the first member to the second member.

A door of a vehicle may include a first door module forming a door skeleton; a second door module coupled with the first door module and forming a door window; and a door frame coupled to the first door module and engaged with the second door module; wherein the second door module may include a relatively lightweight material as compared to the first door module, reducing weight and cost of the door for the vehicle.

A joint assembly comprising at least one extruded profile member and at least one molded member connected to the profile member by an injection molding process. The extruded profile member comprises at least one pre-processed structured surface area adapted to increase grip between the profile member and a molding tool during the molding process. A method for forming a joint assembly is also disclosed, comprising the steps of comprising: inserting an extruded profile member in a molding tool, the extruded profile member and/or the molding tool having a structured surface area to increase the friction between the molding tool and the extruded profile member; clamping the molding tool and bringing the structured surface in contact with the molding tool and/or the extruded profile member to hold the profile member in place, and injecting material into the molding tool to produce a molded member connected with the extruded profile member.

A window frame assembly for a vehicle has a cage frame segment connectable to a roll cage, a door frame segment connectable to a door having a hinged end and an opening end such that its first end is disposed proximate the opening end and its second end is disposed proximate the hinged end, and a linking frame segment having a first end pivotable about a pivot axis for pivoting the linking and door frame segments relative to the cage frame segment and a second end movably connected to the door frame segment such that the linking frame segment moves relative to the door frame segment as the linking and door frame segments pivot about the pivot axis, the cage, door and linking frame segments together forming a frame. Door assemblies for vehicles, window frame kits for vehicles, and vehicles provided with same are also disclosed.
