Abstract:
One end of a toothed cable is connected to a rear door of a vehicle. The toothed cable moves forward and backward, thus opening and closing the rear door. A drive motor imparts a moving force to the toothed cable. An electromagnetic clutch connects the drive motor to the toothed cable and disconnects the drive motor from the toothed cable. A speed sensor detects the movement of the toothed cable when the electromagnetic clutch is set to a disconnected state. A control unit sets the electromagnetic clutch to a connected state when the movement of the toothed cable is detected and actuates the drive motor to allow the toothed cable to move in the same direction at that in which the toothed cable is moving. When the completely opened or closed rear door is moved to some extent in a closing direction or an opening direction by an operator's hands, the rear door is automatically closed or opened by the drive motor.
Abstract:
A powered sliding-door system of an automobile with a sliding-door drive device A and an automatic door closer B. The sliding-door drive device A has a box-like case body 1 opening downward, a case cover 2 covering the opening of the case body 1. A pair of guide pulleys are rotatably supported by axes, and each axis stands on the front end and the rear end of the case in slanting posture. A loop of cable is arranged between the pair of guide pulleys so that a working side is arranged outside of the case body and a return side is arranged in the case body. The loop of cable is driven by an motor driven actuator 12.
Abstract:
A packing mounting structure for a vehicle door powered sliding device comprises an elongated guide rail fixed to a side panel of a vehicle body, a sliding door mounted on the body, a powered sliding unit arranged on an interior side of the side panel, a wire cable provided between the sliding door and the powered sliding unit, a pulley holder provided in the vicinity of one end of the guide rail and having a first pulley around which the cable wire is set, a cable hole formed on the side panel in the vicinity of the one end of the guide rail for passing the wire cable through the side panel, a flexible packing member mounted in the cable hole to close a gap between the cable hole and the wire cable. The pulley holder is fixed to the side panel by either of a screw or bolt. The packing member has an inserting portion which is inserted into the cable hole, and a large-diameter portion which has a diameter sufficiently larger than that of the cable hole and abuts on an inside surface of the side panel when the inserting portion is inserted into the cable hole. The large-diameter portion is firmly sandwiched between the pulley holder and the side panel.
Abstract:
A window regulator for raising a lowering a window pane in a motor vehicle. The regulator includes a scissors linkage including crossed lever arms connected at a pivot axis. The lever arms are attached at their upper ends to spaced points on the lower edge of the window pane and a cable is connected to the linkage at the pivot axis of the crossed arms. The cable is wrapped around a drum driven by a motor and is further trained over an upper pulley positioned above the pivot axis of the linkage and a lower pulley positioned below the pivot axis of the linkage. The regulator further includes a lower cross rail defining a rear pivot pivotally mounting the lower end of one of the lever arms, an intermediate pivot pivotally mounting the lower pulley, and a forward slot slidably mounting the lower end of the other lever arm. The arrangement is such that movement of the cable through a first distance results in movement of the windowpane through a second distance greater than the first distance, thereby providing a speed multiplier effect.
Abstract:
The invention relates to a cable-tensioning device associated with a rail (3) having at its ends (4, 5) two points for returning at least one cable (8), characterized in that one (4) of the said ends of the rail includes: a rotary cam (12); a cam-support element (7); a spring (13) coaxial with the cam (12) and having two angularly offset radial tabs (32, 33), a first tab (33) bearing on a stop (19) formed on the support element (7), and the second tab (32) extending inside the cam (12) and being designed to slide over a non-return means (20) arranged on the support element (7) after the cam has rotated through a first travel, this non-return means being shaped to prevent any return of the second tab (32) after the tabs of the spring (13) have become angularly separated by at least the length of the arc between the non-return means (20) and the stop (19), the cable (8) being engaged in grooves (30, 31) formed at the periphery of the cam. This invention has application to motor vehicle door window lifters.
Abstract:
A tension apparatus of a vehicle door powered sliding device comprises a motor fixed to a base plate, a wire drum mounted to the base plate by a first shaft and rotated by the motor, a wire cable provided between a vehicle sliding door and the wire drum for pulling the sliding door forward or rearward when the wire drum rotates, first and second tension arms rotatably mounted on the first shaft and having tension rollers which makes contact with the wire cable, an intermediate lever rotatably mounted on the first shaft, an adjusting member for fixing the first tension arm and the intermediate lever so that an angle of the first tension arm and the intermediate lever can be adjusted, a tension spring provided between the intermediate lever and the second tension arm.
Abstract:
A window regulator employs a drive cable to regulate opening and closing of a window in a vehicle. The drive cable is attached to a glider which is attached to the window, and extends around a first and second guide means and a drive drum. Rotation of the drive drum causes movement of the cable which in turn causes movement of the window. One of the guide means is slidably mounted and coupled to a spring which causes the guide means to apply tension to the drive cable. The spring is positioned along substantially the same axis along which the slidably mounted guide means may travel.
Abstract:
A cable window lifter with a driving unit includes a drive housing having an internal cavity therein. A cable drum is disposed within the internal cavity and has an internal gear provided along an internal portion of the drum. A pinion gear is disposed within the internal portion of the cable drum and includes teeth that engage the internal gear of the cable drum. The pinion gear is driven manually or by a motor. A support core is disposed between a portion of the internal gear of the cable drum and a portion of the pinion gear teeth. The support core prevents the lateral deflection of the pinion gear teeth out of the internal gear of the cable drum during imposition of an overload force onto the pinion gear, thereby assuring improved running quality of the driving unit and reducing the forces occurring in the driving unit.
Abstract:
An operator for a window has a chain as an operating member, a sprocket wheel for advancing and retracting the chain, and a counterbalancing spring operatively connected to a shaft of the sprocket wheel.
Abstract:
A base member and a fascia are assembled to form a hollow door section which is filled with insulative material. Adjacent sections are coupled along respective longitudinal edges for angular and spatial displacement. The base member is extended from a selected plastic with male and female coupling components extending continuously along respective longitudinal edges. A plurality of mounting members projecting from the lateral edges of the sections matingly and slidably engage the semi-cylindrical guide surface of a tract for reciprocal vertical movement of the door. The door may be partially raised for spatial displacement of the sections whereby flow-through ventilation openings are exposed. In a specific embodiment, a flexible drive screw is rotatably carried within the track for powered operation of the door.
