Patent number: 4649669Abstract: Construction of a door frame in a motor vehicle including a first channel for holding a door weather strip and a second channel contiguous to the first channel on the outboard side for holding a door glass run. The first and the second channels are formed by a continuously bending plate member. A bottom portion of the first channel is a double-ply structure having a rear surface directed toward a compartment and an outer end section. The second channel is formed by a pair of bent extensions extended in two directions, thereby separating each other from the outer end section of the bottom portion. The pair of bent extensions are arc-welded at respective bending corner portions positioned along the outer end section of the bottom portion of the first channel, to integrally connect the pair of bent extensions. The door glass run is mounted along the pair of bent extensions substantially covering and concealing the bending corner portions.Type: GrantFiled: August 15, 1985Date of Patent: March 17, 1987Assignees: Toyota Jidosha Kabushiki Kaisha, Aishin Seiki Kabushiki KaishaInventors: Yuji Okamoto, Shunichi Nakamura

Patent number: 4635398Abstract: A watertight window assembly adapted to be mounted in an automobile comprises a window frame, two sliding panes, weather strips which are mounted in a guide groove formed in the frame and which abut on the panes in a watertight manner, frame members mounted to the opposite ends of the panes, and a seal member of a resilient material. The seal member is mounted to one of the frame members and abuts on the other in a watertight manner. The end portions of the frame members and of the seal member are received in the weather strips. The portions of the frame members which bear on the weather strips are inclined to the direction in which the panes slide. These inclined portions face the panes.Type: GrantFiled: March 25, 1985Date of Patent: January 13, 1987Assignee: Aisin Seiki Kabushiki KaishaInventor: Shunichi Nakamura
