  • Patent number: 5932931
    Abstract: When a closing end of a vehicle windowpane is located at the upper side of a preset point P1 while the windowpane is closing, an obstacle pinched between a window frame and the windowpane is detected by a window frame sensor. When the closing end of the vehicle window is located at the lower side of a preset point P2, the pinched obstacle is detected by the window frame sensor and a motor rotation speed sensor, which indicates changes in motor driving load. This prevents a vehicle window control system from operating erroneously when an obstacle is pinched at a slope portion of the window frame.

  • Patent number: 5880421
    Abstract: To provide a power window apparatus which can reliably actuate an anti-pinching mechanism even in a window provided with a side visor, a cord switch operable in response to a specific external force is mounted in a joining part of a side visor between a window frame and the side visor. The cord switch senses the external force acting on the side visor, reliably detecting a foreign object pinched between a window glass and the side visor.

  • Patent number: 5774046
    Abstract: In a power window apparatus, an external force which develops at the time of catching foreign objects in a window is detected directly by a window frame sensor and indirectly by a motor load detection circuit. Automatic window closing operation is disabled when the external force exceeds a first and a second predetermined levels of the window frame sensor and the motor load detection circuit, respectively. When the window frame sensor fails, the window closing operation is disabled and a warning is provided at the time the external force detected by the load detection circuit reaches a third predetermined level. Alternatively, the automatic window closing operation is disabled when the external force exceeds the first or the second predetermined levels of the window frame sensor or the motor load detection circuit, respectively. When the window frame sensor fails, the window closing operation is disabled and the warning is provided at the time the external force reaches the second predetermined level.

  • Patent number: 5754017
    Abstract: To improve the detection reliability in the detection of sticking of a foreign matter and minimize a sticking load, a power window is provided with a window frame sensor disposed along the inner peripheral edge of a window frame and a drive motor for advancing and retreating a window glass in accordance with an external signal. A control circuit makes a duty control for a transistor to decrease the operating speed of the window glass when the pressure detected by the window frame sensor becomes larger than a predetermined value during a closing operation of the window glass. Thereafter, when the drive load of the drive motor exceeds a predetermined value, a relay is switched over to operate the window glass reverse in the opening direction.

  • Patent number: 5728983
    Abstract: A pressure-sensitive cable switch includes a pair of metallic conductors arranged in opposing relation to one another on the neutral axis for bending within the cross section of a rubber tube, and extend in the longitudinal direction of the tube. A pair of belt-shaped electrodes made of conductive rubber material or other conductive materials and embedding the metallic conductors therein, are disposed to oppose each other on the inner circumferential surface of the robe with respect to the neutral axis for bending. The electrodes extend in the longitudinal direction of the tube. Therefore, an erroneous operation of the cable switch at a part where the switch is bent is prevented, and furthermore the cable switch operates while coping with a wide range of load application angles.
