Abstract

The motor vehicle, particularly passenger car (1) comprises a scissor style door (5) whose rotational axis is provided outside of a door frame in the front vehicle area. The scissor style door is pivoted in a mudguard contour or in a curved track, where a mounting plate is provided for the scissor style door on a circular path section at a distance around the rotational axis.

Description

The The invention relates to a motor vehicle with a scissors door.

scissor doors are vehicle doors that are in the area of the A-pillar are posted and forward above by means of a pivoting movement to open an approximately horizontal and outward axis, so scissor-like, wherein the opening process normally by Gas springs is supported. They are mostly in the Car area application and are often with gullwing doors mistaken. Especially known for the use of such Doors is the Italian sports car manufacturer Lamborghini, the scissor doors used.

Around to allow the doors to open upwards, can the shape of the doors and corresponding bodies not be chosen arbitrarily. In addition, must Measures are taken to the doors after opening reliably in its final position hold (usually realized with gas springs). This means - opposite classic, side-opening doors - additional Effort and involves the danger guillotinenartig falling doors in case of failure of the holding system.

From the US 7,328,932 B2 is a car with a scissors door known in addition to the vertical opening movement additionally performs a forward movement, including the door is attached to a fitting that forms a four-bar linkage to the door. In addition, the fitting is designed so that the door on the hinge moves slightly outward.

From the US Pat. No. 6,676,193 B1 is a car with a scissors door known, in addition to the vertically directed rotary opening movement additionally performs a lateral movement, including the door is hinged to a fitting with a rearwardly and outwardly, in particular also downwardly directed pivot axis. The fitting is arranged as usual on a front portion of the door frame.

Consequently the door will open laterally and upwards and moved forward.

The The above scissor doors all have the problem that the underlying their pivotal movement mechanics consuming and complicated, especially because of the lateral movement outward. In addition, these scissor doors difficult to adjust accurately.

In contrast, The object of the present invention therefore consists in a To provide motor vehicle with a scissors door, at the scissors door with a simple mechanism is pivoted while still easy and accurate to adjust.

These The object is achieved by the recited in claim 1 motor vehicle solved.

Thereby, that the pivot axis of the scissors door outside of the door frame in the front area of the vehicle so arranged is that the pivotal movement of the scissors door of a train follows, in about the fender contour or its rounding It is possible, by the displacement of the pivot axis outside the door frame to the front an enlargement to reach the distance of the scissors door from the pivot axis, so that a more accurate or "more sensitive" reachable is because of the increase in distance one minor change in the adjustment on the pivot axis a greater effect of adjusting the scissors door effected in the area of the door frame.

The Pivot axis is preferably in the region of the front wheel.

Especially is one on a circular path section at a distance about the pivot axis Guided holder for the scissor door intended. Thus, the pivot mechanism can be made particularly simple be.

The Holder preferably comprises at least one arm, in particular two arms to which the scissors door is attached.

Of the Distance usually corresponds to the distance of the fender contour from the front wheel axle, so that the bracket performs a movement, the optically seen from the side fender contour or rounding corresponds.

All it is particularly preferred if the pivot axis along the front wheel axle of the front wheel runs. This results in addition to the already mentioned advantages in addition a particularly interesting optical impression and allows a generous Swinging away the scissors door so that they open the door almost completely free, but so close to above the vehicle survives, like the known scissor doors. This allows, if necessary, easily in parking garages to park, the ceiling height is low.

In order to achieve a seal of the scissors door in a simple manner, the scissors door can be designed to be folded over at the upper edge region, ie it overlaps in the closed position the closing area of the door opening or of the door frame, in particular on the roof. So already by the overlap sealing is achieved without the scissors door perform a lateral movement got to.

The The concept outlined above is particularly suitable for use in three-seat passenger cars with a centrally located driver's seat and two rear seats arranged behind it. In such a vehicle allows the scissors door according to the invention a good accessibility to the rear seats, though only one or two doors are provided.

Further Details, features and advantages of the invention will become apparent the following description of an embodiment based on the single drawing, in the

1 a schematic side view of a car with three seats with a scissors door in the closed position and in the open position;

2 a schematic perspective view obliquely from behind the door opening of the car 1 with opened scissors door and

3 a 2 corresponding view, for better clarity of the holder, the fender is shown transparent and both the door itself and the front wheel have been omitted.

In the figures is a three-seat car 1 with a centrally located driver's seat 2 and two rear seats arranged side by side 3 shown.

The car 1 includes a passenger compartment 4 , with two sideways about beside the driver's seat 2 arranged scissor doors 5 in corresponding doorways 6 or door frames are arranged.

In the 1 is the open position of the scissors door 5 With 5a and the closed position of the scissors door with 5b designated.

One recognizes that in such a vehicle the scissors door 5 good accessibility to the rear seats 3 although only two doors at the height of the driver's seat allowed 3 are provided.

The car 1 includes a front axle 7 for the front wheels 8th , each outside of a fender 9 are surrounded. The fender 9 is how special in 2 recognize, opposite the passenger compartment 4 outwardly projecting, so that the fender 9 Seen from above (not shown) the underlying front wheel covers almost from the "main body" protrudes.

The pivot axis 10 the scissors door 5 lies outside the door frame 6 in the front of the vehicle so that the pivoting movement of the scissors door 5 a lane follows that roughly matches the contour of the fender 9 or whose rounding corresponds. For this purpose, the pivot axis is arranged in the region of the front wheel, the pivot axis runs along the front wheel axle of the front wheel or coincides with it.

The scissors door 5 is about a bracket 11 at the pivot axis 10 hinged.

The holder 11 is designed as an angle and on the axis 10 hinged. Not shown, since without customary and known supportive gas springs etc.

The holder 11 in you through a slot 12 in the fender 9 guided to the outside, so that on the protruding leg 13 the scissors door 5 can be struck.

As the thigh 13 one on a circular path portion at a distance about the pivot axis 10 Performed guided movement, this does the scissors door 5 also.

The distance corresponds approximately to the distance of the contour of the fender 9 from the front wheel axle 8th or the pivot axis 10 ,

If necessary due to the weight of the door can also two brackets 11 be provided, which then in parallel slots 12 run side by side.

To a good seal the scissors door 5 to reach in the closed state, especially in the critical roof area, is the scissors door 5 at the upper edge area 14 , that is above the window 15 and possibly also on the side in the right side view 16 executed overturned, ie it overlaps in the closed position, the closing area of the door opening 6 or of the door frame, in particular on the roof.
