Abstract:
The invention relates to an actuator for a rear panel (4), on a motor vehicle, for a lid (3) on a boot (2) and a convertible roof, which moves from a position covering the cabin of the vehicle to a position in which it is stored in the boot (2), said roof comprising at least one rear roof part (5). The above comprises a panel support connected to the vehicle chassis (1) by pivots, such that said panel (4) moves from an open position to one of two closed positions, means displacing said panel (4) relative to the support body, elastic retainers for said panel (4) in the direction of the lid (3) and stops (13, 14) between-said panel (4) and said rear piece (5) of the roof when the above is in the closed position.
Abstract:
A device comprising, additionally to the main jack, a balancing jack designed to facilitate manual opening of the hood from the in a forward movement for storing luggage in the trunk, and manual closure of hood in the opposite direction. The balancing jack has its base linked to the main jack and the free end of its piston rod fixed in articulation to the hood. It is designed so as not to obstruct the operation of the main jack for automatically opening or closing the hood. The device further comprises means for actuating the balancing jack to enable the hood to be manually opened or closed.
Abstract:
The rear roof element includes a central element that is movable relative to said rear roof element. The central element is connected on either side of the vehicle to the bodywork by two pivot arms comprising a front arm and a rear arm, and is hinged about respective front and rear hinge axes carried by respective ends of the corresponding pivot arms whose respective opposite ends are hinged to the bodywork of the vehicle.
Abstract:
The invention concerns a rollbar integral with the vehicle body and mobile between a retracted position and a position wherein, when the roof is open, the rollbar projects sufficiently above the vehicle back shelf to protect the passengers in case the vehicle overturns. The rollbar consists of two rollbar elements mutually articulated at the top of the rollbar, the lower ends of each rollbar element capable of sliding along a straight line parallel to the vehicle back shelf and located beneath the shelf.
Abstract:
A trunk lid for a convertible vehicle with a folding roof can be opened on the one hand for stowing the folded roof in the trunk and on the other hand to obtain access to the trunk from the rear for stowing luggage. The front and rear edges of the trunk lid are connected to the bodyshell of the vehicle by latches which either lock or articulate the trunk lid so that it can open either from the front toward the rear or from the rear toward the front.
Abstract:
The present invention relates to a roof opening device, such as a sunroof, comprising a plurality of panels that open at least partially, these panels being adapted for maneuvering into an opened or closed position, either simultaneously or selectively, by means of a series of cams and followers. Preferably, this device is mounted in the roof of a motor vehicle.
Abstract:
A drive and control system for articulated vehicles which normally operates in an efficient push-mode with only the wheels of the rear section being driven, but which operates in a hybrid mode when the vehicle has a tendency to jackknife wherein a controlled torque is applied to the rear wheels of the forward section. The value of the torque is determined as a predetermined increasing function of the magnitude of the connection force at the articulation connection and the magnitude of the articulation angle. In a preferred embodiment of the invention, the drive shaft to the differential which drives the wheels of the rear section also drives a variable displacement hydraulic pump which feeds fixed displacement hydraulic motors connected by overrunning clutches to the rear wheels of the forward section. Thus the average displacement of the hydraulic pump is constant and the torque applied to the middle wheels of the rear section is proportional to the hydraulic pressure, which may be adjusted by temporarily increasing or decreasing the pump displacement. The preferred system may easily be modified to compensate for loss of rear tire traction and to accommodate an hydraulic accumulator for energy storage and dynamic braking.
