The present disclosure relates generally to a convertible top for a vehicle, and more particularly to convertible top assembly for a convertible vehicle.
Vehicles with a convertible top include a roof portion that is moveable between an extended position covering the interior of the vehicle, and a retracted position whereby the interior or passenger compartment of the vehicle is exposed. In an extended position, a front portion of the convertible top is aligned and locked to an adjacent header portion of a windshield, in a retracted position, the roof is disposed within a storage space, typically located behind the passenger compartment. In this example, the convertible top storage space is within the trunk compartment of the vehicle.
While conventional convertible tops work well, it is desirable to provide a convertible top that is compact when folded, operates more efficiently, is easier to assembly and less expensive to produce. Thus, there is a need in the art for a convertible top assembly that is accessible to the vehicle operator, and quickly moves between the extended and retracted positions.
Accordingly, the present disclosure relates to a convertible top assembly. The convertible top assembly includes a front panel member and a rear panel member. The convertible top assembly also includes a main pivot bracket attached to the vehicle. The main pivot bracket includes a forwardly located arm pivotally connected to a rear edge of the front panel member and a rearwardly located arm pivotally attached to a rear edge of the rear panel member, such that an inner surface of the front panel member is adjacent an outer surface of the rear panel member when the convertible top is in a retracted position. To retract the convertible top, the deck lid pivots on a rearward edge along a first pivot axis while a rear edge of the rear panel pivots upwardly about a third pivot axis. At a predetermined time, the front panel pivots rearwardly along an arc and the tonneau cover pivots upwardly about a front edge so that the front panel passes underneath the rear panel and is stowed in the storage compartment, the rear panel closes on top of the front panel, the tonneau closes and the deck lid closes and is latched.
An advantage of the present disclosure is that a convertible top assembly is provided that quickly moves between extended and retracted positions. Another advantage of the present invention is that the convertible top assembly is readily packagable into the trunk of the vehicle. A further advantage of the present invention is that the convertible top assembly is cost effective to implement.
Other features and advantages of the present disclosure will be readily appreciated, as the same becomes better understood after reading the subsequent description taken in conjunction with the accompanying drawings,

The convertible top assembly 12 may include a downstack receiver that is conventional in the art (not shown and latch assembly bat is conventional in the art (not shown) for supporting and/or retaining the retracted hardtop components in the storage area when the top is retracted. The downstack receiver receives and supports the panels 26, 28 in the stowed position. In an example, the downstack receivers are provided in the front portion of the trunk storage area 15.
The convertible top assembly 12 is controlled by a control system e.g., electronic, manual, etc.) that is conventional in the art (not shown) that operatively controls a specific sequence of operations for opening or stowing the convertible top 12 and for closing or extending the convertible top 12. Various steps in the sequence may occur simultaneously. The opening sequence is as follows. The user operates a switch (not shown) that is conventional in the art which opens a latch at a predetermined time, such as the header latches, panel latches and deck lid latches. The switch can be located at any appropriate location that is convenient such as the front console, dash, or the like. The deck lid 14 and deck lid frame 16 pivot upwardly about a rearmost edge of the deck lid 14a along the first pivot axis 22 via a connection link, to uncover the trunk compartment 15 as shown in
The convertible top assembly 12 may include other features, such as a switch (not shown) for operating the top 12. The switch may be in a remotely located, such as on a key fob, or integrally located on the vehicle 10. The control may send a command to a window controller to lower a side window prior to cycling the top. A warning chime may be provided which indicates movement of the top 12. Similarly, raising or lowering of the top 12 may only be allowed under a predetermined vehicle condition, such as when the vehicle 10 is parked. The system may include a number of sensors, such as limit switches that sense the various conditions, such as latch engagement, panel position or the like. The system may include a sensor which determines if the luggage occupies the trunk, and determines if the top 12 can cycle. The system may include an overload sensor for determining if the actuators exceed a given load. In addition, the system may cease operation if an expected condition is not sensed within a predetermined timeout period.
