  • Patent number: 5141283
    Abstract: A slidable roof device for a motor vehicle is provided wherein a roof panel opening of a motor vehicle is openably covered by a flexible member. A front portion of the roof panel opening can be uncovered when a front portion of the flexible member is moved in the rearward direction of the vehicle body. A tilt mechanism is provided at a rear portion of the flexible member so as to tilt up the rear portion thereof and to form at least a clearance between the rear portion of the flexible member and the vehicle roof panel, thereby making sure that rear seat passengers can enjoy more a comfortable ride in the vehicle. Further, the tilt mechanism can be made to operate when the front portion of the flexible member is moved rearwardly so as to tilt up the rear portion of the flexible member to form at least a clearance between the rear portion thereof and the vehicle roof panel when the front portion of the flexible member is opened.

  • Patent number: 5080429
    Abstract: A slidable roof device for a motor vehicle wherein a roof panel opening of the vehicle body is openably and closeably covered with a flexible member. For opening both front and rear portions of the roof panel opening of the vehicle body, the device includes a first drive mechanism which is operatively interconnected with the front portion of the flexible member for moving the front portion thereof to the rearward direction of the vehicle body, and a second drive mechanism which is operatively interconnected with the rear portion of the flexible member for moving the rear portion thereof to the forward direction of the vehicle body. The first and the second drive mechanisms are provided at the rear end of the roof panel opening of the vehicle body.

  • Patent number: 4991903
    Abstract: A drive device for opening and closing a vehicle top includes a pair of control devices each fixed in the side of the vehicle body, a falling pillar swingably supporting the vehicle top on the vehicle body and a pair of extendable link mechanisms that include link rods which are inclinable and which couple a swinging arm of the respective control device with the falling pillar. Each of the control devices includes a housing in which is rotatably positioned at least a portion of an output shaft for rotating the swinging arm, a driving device attached to the housing and generating a rotary driving force, a first reduction gear stage formed as a worm drive which is coupled with the driving device and which is housed in the housing, and a second reduction gear stage formed as a spur gear drive which is coupled with the worm drive for driving the output shaft and which is housed in the housing.

  • Patent number: 4918360
    Abstract: An electric driving device for openable members in which an openable member is opened and closed by rotation of driving shafts provided on right and left sides. The device includes a motor which rotates the driving shafts via a reduction mechanism, and switching relays which switch the rotational direction of the motor. Open and close command switches command the opening and closing of the openable member and a rotation synchronization sensor associated with the motor generates pulses synchronized with the rotation of the motor. A mechanical stopper limits the rotation of the driving shaft which is rotated via the reduction mechanism of the motor and a motor lock detecting means detects locking of the motor by detecting the pulse width generated by the rotation synchronization sensor. Also, an actuation stopping arrangement stops the actuation of an actuation device which supplies current to the motor if a signal is generated by the detection apparatus that detects locking of the motor.
