Abstract

The invention relates to a vehicle door for a convertible with a door handle (2) with a handle part (5) which can be pivoted from its rest position into an actuating position for opening the vehicle door (1) and a window pane (13) which can be moved by means of an electric window motor (12) is sealed in the closed state by a seal of the vehicle roof. In order to achieve in a simple manner that when the vehicle door (1) is opened, the window pane (13) is lowered from the seal of the vehicle roof as early as possible, the invention proposes that the handle part (5) be operatively connected to an electrical switch ( 9; 9 ') and this is connected via an electrical connection (10) to a control device (11) controlling the window lift motor (12), such that when the handle part (5) is pulled, the switch (9) activating the control device (11) ; 9 ') is actuated and the control device (11) generates a control voltage which activates the window lift motor (12) until the window pane (13) is no longer inside the seal of the vehicle roof. <IMAGE>

Description

The invention relates to a vehicle door for a convertible with a door handle with its Resting handle part pivotable into an actuating position for opening the vehicle door and a window pane which can be moved by means of an electric window lifter according to Features of the preamble of claim 1.

Since the side doors of passenger vehicles with a folding top (convertibles) usually do not have an upper pane frame, the sealing takes over against the possible penetration of moisture on the roof, etc. Vehicle roof gasket.

To avoid problems with opening and closing the side vehicle door, though the disc is in its upper position, it has already been proposed lower the respective window slightly before opening the vehicle door. For this, a Switches arranged in the area of the rotary latch of the door lock. Once the door opened and thereby the rotary latch is pivoted, the switch generates a pulse and activates an electrical control device. This affects the window motor, which then lowers the pane by a few centimeters.

A disadvantage of this known vehicle door has been that the lowering of the The window and the opening of the vehicle door take place practically simultaneously, which in particular can cause problems when opening the door if it opens very quickly becomes.

The invention has for its object a vehicle door of the type mentioned specify in which it is achieved in a simple manner that in the opening process Lowering of the side window takes place earlier than this for the vehicle doors mentioned above the case is.

This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the subclaims.

The invention is essentially based on the idea that the control of the switch, which activates the window lift motor via the control device, not through the Rotary latch in the door lock, but by the handle part of the door handle or by one with the Handle part connected part takes place.

The attachment of the switch and its specific control by the handle part can done in different ways and depends on the door handle used and the space inside the vehicle door.

When using a door handle with a bracket that can be attached from inside the door it has proven to be advantageous to also attach the switch to the bracket. It has proven to be practical for reasons of space, the switch on the outside to be arranged on the bracket. The handle part and the switch are in such a Embodiment advantageously over a pivotable and two axially spaced Lever arms having lever arrangement connected to each other. The first is here Lever arm directly or via another lever with the handle part in operative connection, and the second lever arm acts on the pivoting movement caused by the handle part the switch. The axis of rotation connecting the two lever arms is through an opening of the corresponding side wall of the bracket is pivoted through.

The handle part can be both a bow handle and a flap handle act. It can also activate the window motor to lower the Washer from the seal of the vehicle roof through both on the door outside and switches also arranged on the inside door handle.

Both electrical and optical or magnetic switches can be used as switches become.

The control device for controlling the window lift motor can both inside and also arranged outside the vehicle door and part of a central control device of the Vehicle.

Further details and advantages of the invention result from the following exemplary embodiments explained with reference to figures. Show it:

1 shows a schematic representation of the detail of a vehicle door according to the invention with a door handle, a control device and a window regulator;

2 shows the view of a bracket shown in dashed lines for an outside door handle with a switch attached to it and a lever arrangement for transmitting the pivoting movement of the handle part to the switch, seen from the inside of the door, and

3 shows a side view of the lever arrangement shown in FIG. 2, omitting the bearing bracket.

In Figure 1, 1 denotes a vehicle door for a convertible and 2 denotes an outer door handle. The door handle 2 comprises a bearing bracket 3, via which it on the outer skin 4 of the Vehicle door 1 is fastened, and a handle part 5 designed as a bow handle.

The handle part 5 has at its front end a handle dome, which in the interior 7 of the Vehicle door 1 is sufficient and is provided with a cam 8, the function of which follows is still described.

A microswitch 9 is attached to the bearing bracket 3 and is connected via an electrical connection 10 is connected to a control device 11 located in the vehicle door 1.

The control device 11 is in turn one with a window regulator motor 12 not in detail shown window lifter for lifting and lowering a side window 13 an electrical connection 14 connected. In the closed state of the disc 13 is this into a not shown e.g. U-shaped seal of the corresponding vehicle roof postponed.

If the vehicle door 1 is now to be opened from the outside, the vehicle owner pulls it Handlebar outwards in the direction of arrow 15. As a result, the cam 8 presses against the Microswitch 9, which generates a corresponding switching signal. This is from the Control device 11 received, which in turn the window motor 12 for a predetermined Period activated, such that the side window 13 from the closed position is lowered so far that the upper edge of the disc 13 below the seal of the vehicle roof. Then the vehicle door opens.

The invention is of course not based on the embodiment described above limited. In particular, it will often not be possible for an on the handle dome attached cam acts on a corresponding microswitch, since the handle dome e.g. also acts on a lock linkage or on a spring-loaded rotating bracket etc. As a rule, it will therefore be necessary to use a handle and switch to connect pivoting lever assembly. A corresponding embodiment is shown in Figures 2 and 3.

The bearing bracket indicated by dashed lines is designated 3 '. Inside the bearing bracket 3 'there is a rotating bracket 16 which is pivotable about a first axis of rotation 17 in the bracket 3 'is mounted. On the rotary bracket 16, the grip dome 6 'engages one behind the bow handle located on the image plane. The rotary bracket 16 is of a not shown Torsion spring acts and serves primarily to the bow handle in its rest position hold, unless it is operated. Of course, it can also be used as Release lever used to operate a lock linkage or a Bowden cable become.

On the rotary bracket 16, a driver 18 is arranged, which has a two-armed transmission lever 19 on a microswitch attached to the outside 20 of the bracket 3 ' 9 'acts. The two lever arms 21, 22 of the transmission lever 19 face each other an axial distance, which is selected such that the first lever arm 21, the is rotatably connected to the driver 18 via a fork-shaped end 23, located within of the bracket 3 'and the second lever arm 22 outside the bracket 3' in the area of the microswitch 9 '. It is the one that connects the two lever arms second axis of rotation 24 through an opening 25 of the side wall 26 which acts as a bearing bush of the bracket 3 'passed pivotally.

If the handlebar is now open to the outside of the vehicle door (i.e. in Fig. 2 to the opposite Side of the image plane and down in Fig. 3), the rotating bracket 16 in Fig.2 pivoted down about the axis of rotation 17. The driver 18 pivots then the first lever arm 21 also down about the second axis of rotation 24, and the second lever arm 22 is pressed upwards against the microswitch 9 ′, so that this one corresponding switching signal generated. The switching signal is then in turn sent to a control device to operate a window regulator motor.
