Abstract

A roof panel connected to a vehicle body through at least a pair of front pillars and a pair of rear pillars is provided with a large aperture on the roof with a front header and a pair of roof side rails. A rear window glass panel is fixed to the rear pillars and the rear header. A flexible top is contractible or expandable in a longitudinal direction of the vehicle and disposed so as to uncover or cover the roof aperture. When the flexible top closes the roof aperture, it is abutted at its front end portion with the front header, at its side end portions with the roof side rails, and at its rear end portion with the rear header. When the top is in a folded state, it is located in a second posture nearby the trunk lid. The top can be transferred up to its third posture in a position nearby a lower end portion of the rear window glass panel. Vertical movement of the top at least between the second and third postures can automatically be performed by a control unit in condition where the vehicle halts. The vertical movement of the top can be continued when the vehicle is shifted to its running state in the course of a transfer thereof between the second and third postures, thereby ensuring a transfer to the second posture or to the third posture.

Claims

1. A flexible top apparatus of a vehicle having:

a roof panel connected to a vehicle body through at least a pair of left-hand and right-hand front pillars and a pair of left-hand and right-hand rear pillars;

said roof panel being provided around its perimeter with a front header, a pair of left-hand and right-hand roof side rails, and a rear header, said front header, pair of left-hand and right-hand roof side rails and rear header defining a roof opening formed in said roof panel; and

a rear window glass panel fixed to said rear pillars and said rear header;

comprising;

a flexible top having a size as substantially large as the roof opening in a state in which said flexible top is longitudinally unfolded and expanded and being disposed to selectively take a first posture in which the roof opening is closed and a second posture in which said flexible top is longitudinally contracted at a position in the vicinity of said rear header to open the roof opening;

a guide means disposed between said flexible top and the vehicle body for guiding said flexible top in a contracted state between said second posture and a third posture located in a vicinity of a lower end portion of said rear window glass panel, said guide means extends from the lower end portion to in front of the rear header;

a driving means for transferring said flexible top between the second posture and the third posture;

a switch for selectively giving an instruction to start transferring said flexible top between the second posture and the third posture;

a state detecting means for detecting a presumed standing state in which the vehicle halts;

a first control means for controlling the transfer of the flexible top when the vehicle is in the presumed standing state; and

a second control means for continuing control of the transfer of the flexible top regardless of whether or not the vehicle is shifted from said presumed standing state to a presumed running state after the flexible top starts transferring between the second posture and the third posture.

2. A flexible top apparatus as claimed in claim 1, wherein said driving means is a first driving means, and said flexible top apparatus further comprising:

a second driving means for transferring the flexible top between the first posture and the second posture;

a second switch for selectively instructing start of transferring the flexible top between the first posture and the second posture;

a third control means for controlling the transfer of the flexible top between the first posture and the second posture in response to a control start signal from the second switch; and

a fourth control means for inhibiting the control for transfer of the flexible top when the vehicle is shifted from said presumed standing state to said presumed running state after the flexible top starts transferring between the first posture and the second posture.

3. A flexible top apparatus as claimed in claim 1, further comprising:

a second driving means for transferring the flexible top between the first posture and the second posture;

a second switch for selectively instructing start of transferring the flexible top between the first posture and the second posture;

a third control means for controlling the transfer of the flexible top between the first posture and the second posture in response to a control start signal from the second switch; and

a fourth control means for continuing the control for transfer of the flexible top when the vehicle is shifted from said presumed standing state to said presumed running state after the flexible top starts transferring between the first posture and the second posture.

4. A flexible top apparatus as claimed in claim 2, wherein the third control means starts transferring said flexible top between said first posture and said second posture when the vehicle is in said presumed standing state.

5. A flexible top apparatus as claimed in claim 3, wherein the third control means starts transferring said flexible top between said first posture and said second posture when the vehicle is in said presumed standing state.

6. A flexible top apparatus as claimed in claim 3, wherein the third control means includes means for closing said flexible top from said second posture to said first posture regardless of said presumed standing state or said presumed running state.

7. A flexible top apparatus as claimed in claim 2, wherein the second driving means and the first driving means for transferring said flexible top between the second and the third posture are constituted by different electrically-driven motors.

8. A flexible top apparatus as claimed in claim 2, wherein the second driving means and said driving means for transferring said flexible top between the second posture and the third posture are driven by a common electrically-driven motor.

9. A flexible top apparatus as claimed in claim 1, wherein the flexible top is in a state in which it is longitudinally folded when it assumes the second posture.

10. A flexible top apparatus as claimed in claim 9, wherein the guide means comprises a pivotable link member.

11. A flexible top apparatus as claimed in claim 10, further comprising a hard board member, on which the flexible top in the second posture is placed, in a position nearby the rear header;

wherein the hard board member is mounted to the vehicle body through the link member; and

wherein the flexible top is transferred between the second posture and the third posture, together with the hard board member, in accordance with a pivotal movement of the link member.
