  • Patent number: 4559740
    Abstract: A slider assembly for an automotive sliding door is more compact than conventional ones. This compact slider assembly can be obtained by overlapping part of one of vertical and horizontal rollers and the plane of the other in order to reduce the distance between the rotational axles thereof. A bracket supporting the rollers is formed with a recess receiving part of one of the rollers. In the preferred structure, the periphery of the recess is essentially concentric to the chosen one of the rollers.

  • Patent number: 4541201
    Abstract: A sealing structure for an automotive sliding door comprising a lower seal attached to the lower edge of the sliding door. The lower seal is adapted to contact a lower vertical edge portion of a lower guide rail upon which the sliding door is slidably suspended to establish a water-tight seal between the guide rail and the lower edge of the sliding door. The guide rail is mounted on a lower side frame of the automotive vehicle, and a weatherstrip is also installed on the vehicle body lower side frame. The weatherstrip is adapted to contact the inner surface of the sliding door to establish another water-tight seal. In this way a double seal is obtained around the lower edge of the sliding door, and the lower guide rail is satisfactorily isolated from leaking moisture.

  • Patent number: 4496186
    Abstract: A sealing structure for an automotive vehicle prevents turbulent air flow around a front pillar and thus reduces noise due to wind. This seal is provided by a weatherstrip which also seals the space between the front pillar and a front door against water. The weatherstrip is provided with an extension extending towards the opening of the above space to close same. The extension lies approximately flush with the outer surfaces of the front pillar and the front door to form a substantially continuous external surface. This continuous external surface around the front pillar improves the aerodynamics of the vehicle.

  • Patent number: 4364601
    Abstract: A sun roof is arranged to descend without tilting (thus avoiding abrasion of the weather stripping) into a space below the roof panel and thereafter to slide into a housing for same. The actuating mechanism either reduces or maintains the distance between the shoes, which serve as bogies for the roof, to induce smooth sliding of the unit when moving in and out of the storage position, and applies the driving force to the leading pair of shoes to further increase the smoothness of the sliding when moving the unit from the storage housing. When tilting the sun roof for ventilation, the mechanism lifts one end and maintains the other end essentially stationary by applying a slight lift which offsets the tendency for the other end to sink due to the tilting. Again the weather strip is protected from abrasion.

  • Patent number: 4351561
    Abstract: A locking device for an openable automobile roof lid is provided. The base plate of the device is fixed to the edge of an opening formed in the roof panel. It is further formed with a hook portion at its one end. The lid to close the opening carries a handle at a portion corresponding to the hook portion of the base plate. To this handle, one end of a link is pivotally connected. From the other end of the link, a shaft pin projects and is rotatably fitted in the hook portion. To hold the shaft pin in the hook portion the base plate is provided with a stopper which is adapted to retract and release the shaft pin from the hook portion.

  • Patent number: 4346932
    Abstract: A hinge device is provided for an openable automobile roof having a detachable lid. The device includes a hinge housing at an edge portion of the opening in the automobile roof panel, a linear passage formed in the hinge housing, a guide portion projected in front of the entrance to the linear passage, a hinge tongue attached to the lid at its front edge, a linear fitting part formed on the hinge tongue and adapted to fit the passage, and a stopper part formed also on the hinge tongue and adapted to abut the guide portion when the lid is placed at the closing position.

  • Patent number: 4337975
    Abstract: A sunshine roof structure of a vehicle, comprising a roof panel having an opening formed therein, a light-transmitting panel pivotally movable between an angular position closing the opening and an angular position allowing the opening to be open, a light-shield panel underlying and pivotally movable with the light-transmitting panel, and a latch mechanism for providing releasable engagement between the light-transmitting and light-shield panels so that the light-shield panel can be detached from the vehicle body by unlatching the latch mechanism.

  • Patent number: 4258950
    Abstract: Disclosed are a roof panel and a rear fender outer panel have flange portions, respectively. The flange portions define sides of a back door receiving opening. The roof panel and the rear fender outer panel are respectively fitted with support members which are constructed and arranged to cooperate with the flange portions, a weather strip and a frame of a back door assembly to define adjacent said receiving opening a drip trough the depth of which is larger than its width. The frame of the back door assembly is constructed and arranged to have a box-like section including a bottom side and to engage the weather strip at the wall portion defining the bottom side whereby the frame is markedly reduced in width, resulting in an increased vision area of a glass panel of the back door assembly and therefore an improved visibility as well as an improved appearance.

  • Patent number: 4168594
    Abstract: A remote controller for remotely controlling the opening position of a hinged window of a vehicle, which comprises a flexible cable with one end operatively connected to a free end portion of the window, a cable guide member for guiding the cable, an operating device connected to the cable to longitudinally move the same causing opening and closing movements of the window when operated, and a one-way braking mechanism for braking the longitudinal movements of said cable induced by the opening and closing movements of the window while freely permitting the movements of the cable via the operation of the operating device.
