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 method for manufacturing a door sash formed from a single plate material includes: a roll-forming step of providing a gap portion between the plate materials forming a stepped section and roll-forming a periphery of an end portion of a plate material extending from a tubular section, so as to come into contact along the plate material forming the stepped section; a press working step of pressing the end portion of the plate material to a position where the end portion does not protrude further toward the side on which a weather strip is fitted than a surface of an overlapping section and a surface of the tubular section on the side on which the weather strip is fitted, while crushing the gap portion; and a welding step of continuously laser-welding the overlapping section along a longitudinal direction of the door sash.

A door sash which is formed by roll-forming from a single plate material and in which a weather strip is fitted includes: an overlapping section formed by making the plate materials overlap each other; a tubular section formed to extend from a car-interior-side end portion of the overlapping section; and flange sections and respectively formed to protrude from a car-exterior-side end portion of the overlapping section to both sides, in which a periphery of an end portion of the plate material extending from the tubular section is formed so as to come into contact along a plate material forming the overlapping section on the side on which the weather strip is fitted, and the vicinity of an end portion of the plate material forming the overlapping section, in which deformation has occurred during the roll-forming, protrudes to the inside of the tubular section.

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 door frame includes: a column, wherein the column includes: an outer member; and an inner member, which is attached to the outer member and of which at least a part is located at an inner side of the vehicle, wherein the outer member includes: a base portion; and a first bent portion that is bent at an end portion of the base portion and extends to the inner side of the vehicle, wherein the inner member includes: a side portion that has faces, which respectively face the base portion and the first bent portion, and wherein the first bent portion of the outer member is welded to the side portion of the inner member in a state where a gap is formed between the base portion of the outer member and the face of the side portion of the inner member, which faces the base portion.

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.

A molding configured not to be misaligned with a predetermined mounting position provides a vehicle with good appearance, avoids in advance interference with other parts when a door is opened or closed, and reduces wind noise while the vehicle is running. An end cap having a locking part is crimped to a rear end of a molding. An upper glass run has, at its rear end, an insertion slot into which the locking part is inserted. The locking part is inserted in the insertion slot and locked to the rear end of the upper glass run.

A lateral impact retention system for a vehicle door includes a door window frame retainer configured for mounting to the vehicle body and a pivoting catch configured for mounting to a window frame of the door. The pivoting catch engages the retainer when the door is subjected to a door-displacing lateral impact, but is not connected to any door-operating mechanism of the door. During normal operation of the door between the fully closed and open configurations, the pivoting catch automatically inserts into and displaces from the retainer.

A vehicle door frame includes a pillar, a frame molding, and a welded part. The pillar has a first abutting surface and a first outer surface. The upper frame has a second abutting surface and a second outer surface. The frame molding extends along the upper frame to cover an outside of the upper frame in the lateral direction of a vehicle, and has an inner surface facing the first outer surface and the second outer surface with a gap. The welded part is located at a boundary between the first outer surface and the second outer surface, extends along the first abutting surface and the second abutting surface, faces the inner surface, and bonds the pillar and the upper frame together.
