  • Patent number: 5372401
    Abstract: A sliding roof includes a light transmitting sliding sunroof and a light isolating sliding sunshade disposed beneath the sunroof. The light transmitting sliding sunroof opens a roof opening only while the light isolating sliding sunshade is in its open position. Also, the light isolating sliding sunshade closes the roof opening only while the light transmission sliding sunroof is in its closed position. Damage to the light isolating sliding sunshade, therefore, is prevented.

  • Patent number: 5310241
    Abstract: Disclosed is a flexible top vehicle with its flexible top so disposed as to open or close both the forward portion and the rearward portion of a roof opening separately. The flexible top is disposed at the roof opening portion and it has a forward slider disposed at its forward end portion and a rearward slider disposed at its rearward end portion, thereby capable of opening the forward and/or rearward portion of the roof opening of the roof by folding or extending the flexible top from or to both end portions thereof. The forward slider is engaged with a forward stopper mounted on a member of the vehicle body, thereby closing the forward portion of the roof opening with the forward end portion of the flexible top, and vice versa. When the flexible top is extended to its maximum length and closes the entire length of the roof opening, the distance between the forward and rearward sliders is set to be smaller than the distance between the forward and rearward stoppers.

  • Patent number: 5169206
    Abstract: A slidable roof control device for a motor vehicle wherein a roof panel opening of a motor vehicle is covered with a slidable roof which can be opened both in forward and rearward directions of the vehicle body. The control device includes a first forwardly located ON/OFF command mechanism operable from the driver seat for commanding a drive mechanism to open or close the flexible member, a second rearwardly located ON/OFF command mechanism operable from the rear seat for commanding the drive mechanism to open or close the flexible member, and a control mechanism. The control mechanism is responsive to outputs from the first and second ON/OFF command mechanisms for controlling the activation of the drive mechanism and for restricting the closing motion of the rear portion of the slidable roof as a result of commands from the first ON/OFF command mechanism.

  • Patent number: 5152577
    Abstract: A flexible top vehicle or canvas top vehicle is provided with a flexible top or canvas top made of a flexible member so as to cover its roof opening. The flexible top is so disposed as to allow both of its front end and rear end to be transferred forwards or rearwards. The front end of the flexible top is associated with a first driving motor while the rear end thereof is associated with a second driving motor. The first and second driving motors are arranged to be operated by turning a forward-moving switch or a rearward-moving switch on, thereby transferring the flexible top placed in a middle position of the roof opening in a folded state in forward and rearward directions. The flexible top maintains its folded state prior to transfer even after it has been transferred.
