Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates, in general, to automobiles and, more specifically, to automobiles having a convertible top.

2. Description of the Prior Art Vehicles, such as automobiles have been provided with a convertible top comprised of a fabric covered framework formed of articulatable side rails, interconnecting cross bows and an operating linkage typically powered by hydraulic cylinders for raising and lowering the top between an errected position over the vehicle body and a retracted or lowered position within a storage compartment behind the rear seat of the vehicle. Due to the lack of a rigid roof structure in such vehicles when the convertible top is in the lowered position, the thickness of the vehicle body panels must be increased or additional reinforcements or braces added to the vehicle body panels to provide the necessary structured strength for the body.

A common reinforcement added to increase the structural integrity of a vehicle body having a convertible top is a rigid cross panel member mounted within the passenger compartment behind the rear seat and extending between and joined to the quarter panels of the vehicle. The cross panel is typically solid in form and extends vertically between the compartment floor pan and the top of the rear seat of the vehicle. The cross panel member is spaced from the rear trunk support member and forms a well or storage space for the convertible top when the top is in the lowered position. While the cross panel member is effective in providing sufficient structural strength to the vehicle body, it necessarily adds considerable weight to the vehicle and, therefore, increases the cost of the convertible top option.

While the additional support structure required for a vehicle body having a convertible top can easily be provided during the design stages of the vehicle, difficulties are encountered when a vehicle having a rigid or hard top is to be converted into a vehicle with a convertible top. Since the required structural strength is not designed into the vehicle body itself, many additional support members and reinforcements are required which necessarily increases the cost and complexity of the convertible top conversion.

Thus, it would be desirable to provide a vehicle having a convertible top which overcomes the problems of previously devised vehicles having convertible tops relating to the number and size of the components needed to be added to the vehicle to provide the requisite structural strength for the vehicle body. It would also be desirable to provide a convertible top which can be installed as a conversion assembly on a vehicle initially having a rigid hard top.

SUMMARY OF THE INVENTION

The present invention is a vehicle having a convertible top. Reinforcement members are secured to certain interior body panels of the vehicle to provide the requisite structural support for the vehicle body. The reinforcement members include an upper belt line reinforcement joined to and extending across the upper portion of the body quarter panels and the rear upper back panel. Reinforcement members are also secured between the vehicle quarter panels and the wheel house. The belt line and quarter panel reinforcement members define a box-like structure with an aperture formed therein which provides communication between the trunk and passenger compartments of the vehicle so as to enable the elongated objects to be stored within the vehicle when the rear seats of the vehicle are folded down.

A header mounted on the upper edge of the windshield of the vehicle includes a laterally extending edge portion recessed below the top surface of the header. First and second seal members are mounted on the header for sealing the front edge of the convertible top. The front edge of the first cross bow of the convertible top is received in the recessed edge portion of the header such that the convertible top is mounted in a flush alignment with the top edge of the vehicle windshield.

Latches mounted on the front cross bow of the convertible top releasably engages apertures formed in the structure surrounding the windshield to lock the top in position on the vehicle. The apertures are located at the intersection of the header and windshield pillar.

The unique vehicle with a convertible top of the present invention provides several features and advantages not found with previously devised vehicles having convertible tops. The support structure added to the interior body panels of the vehicle provides the necessary structural integrity for the vehicle and uniquely enables an opening to be formed between the trunk and passenger compartments so as to enab1e elongated articles to be disposed within the interior of the vehicle when the rear seat of the vehicle is folded down. Such a capability has previously not been provided in vehicles with convertible tops due to the support panels previously utilized to provide the necessary structural strength for the vehicle body.

Furthermore, the unique header attached to the top edge of the windshield enables the first cross-bow of the convertible top to be disposed in-line with the top edge of the header so as to provide a flush, smooth appearance to the front edge of the convertible top. This compares favorably with previously devised attachment methods in which the front edge of the convertible top overlays the upper edge of the windshield of header mounted thereto.

The header and adjoining structure are provided with apertures for releasably receiving latches mounted on the front cross-bow of the convertible top. This unique arrangement eliminates the need for the costly casting that was previously mounted on the top edge of the windshield for aligning and latching the top in the raised position.
