DESCRIPTION:
BRIEF SUMMARY
The invention relates to an actuating device for a pivotal closure member such as a window or pivotal roof of a vehicle of the type comprising a rod articulated at one end on said closure member and whose other end is connected to a rotatable member carrying one end of a cable arranged to roll onto and off at least a portion of said rotatable member, the other end of said cable being secured to a drive means.
The manually controlled actuating devices adapted to move a closure member of a vehicle, so as to bring it by pivotal movement from the open position to the closed position, or vice versa, whether by a device disposed in the vicinity of the element to be moved or by means of a remote actuating means, are known.
There is also known for opening side rear windows conventional systems of ball and socket joints which unfortunately are not accessible to the driver while driving. It has therefore been proposed to provide remote control devices which are for example disclosed in U.S. Pat. No. 3,740,093, FR-A-80.03229 and U.S. Pat. No. 4,918,865.
U.S. Pat. No. 3,740,093 relates to a device comprising a crank disposed on the side panel of the vehicle and connected to the actuating mechanism of the closure member by means of a flexible cable. The crank drives in rotation the cable which effects rotation of the actuating mechanism for opening and closing the forward window of the vehicle confronting that of the driver.
For its part, FR-A-80.03229 describes a device comprising two identical actuating members spaced from each other and interconnected by a flexible cable. The first actuating member is driven in rotation by a manual control handle directly accessible to the driver. The actuating member converts this movement of rotation into linear movement of the flexible member which then drives the rear actuating member which effects a new conversion of the movement and transmits this rotation movement to an articulated rod system of the overcenter type which connects the actuating member to the glass.
The devices described in these documents are relatively bulky and require effort by the user who must exert a rotative movement to actuate the assembly of the device.
There has also been proposed, in U.S. Pat. No. 4,918,865, a remote control system in which an end of a ball and socket joint for opening and closing the closure member is controlled by a drive means comprising an electric motor disposed remotely and two transmission cables rolling up on and unrolling from a drum according to the direction of rotation of the motor. The axle of the drum is fixed to the free end of the ball and socket joint. This known assembly is undesirably large as to the actuating mechanism. The mounting is extremely complicated because the motor is for example mounted at the bottom of the panel. Moreover, the length of flexible cable necessarily introduces imprecision of operation because of the play thus provided.
One of the objects of the invention is therefore to provide an actuating device with pneumatic control, of small size, permitting remotely controlling, by an occupant in the front of the vehicle, a pivoting movement of a closure member such as a window or pivoting roof of the vehicle, between a closed and an open position.
To this end, the control device according to the invention is characterized in that the connection between the rod articulated to the rotatable member is effected by means of a conical pinion meshing with a toothed sector of said rotatable member, the axis of said conical pinion being substantially orthogonal to the axis of rotation of said rotatable member, the drive means being constituted by a linear pneumatic actuator mounted on the support secured to said rotatable member.
To permit the rotation of the rotatable member in both directions, the first cable can be prolonged by a second cable whose one end is carried by the rotatable member and whose other end is secured to a second actuator with linear movement or a double acting actuator. It is also possible to provide an elastic return means in the v
