Patent number: 5310241Abstract: 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.Type: GrantFiled: January 21, 1992Date of Patent: May 10, 1994Assignee: Mazda Motor CorporationInventors: Seiichi Omoto, Kenji Matsumoto

Patent number: 5152577Abstract: 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.Type: GrantFiled: November 29, 1990Date of Patent: October 6, 1992Assignee: Mazda Motor CorporationInventors: Seiichi Omoto, Kenji Matsumoto
