Description

at The invention is based on an open passenger car with a rollover protection device, according to the generic term of claim 1

A generic passenger car is from the DE-OS 17 55 619 known. It has a movable vehicle roof that can be removed by hand. In a closed position, the vehicle roof is located above a passenger compartment, while it is stored in a storage position in a storage compartment of the passenger car. Furthermore, the passenger car comprises a rear element adjoining the vehicle roof when the vehicle roof assumes its closed position. The rear element is fixed and completely formed as a rear window and thus takes both in the closed position and in the storage position of the vehicle roof always the same normal position above a waistline. In addition, the passenger car has a rollover protection device in the form of a fixed, immovable roll bar, which completely spans the passenger compartment in the vehicle width and also firmly connected to the frame of the passenger car and thus is an integral part of the shell.

A similar passenger car is out of the DE 196 49 751 A1 known. The roll bar shown there is also fixedly connected to the shell. However, the vehicle roof is movably held on the vehicle and can be moved automatically or by means of external drive between its closed position and its storage position.

Both known passenger cars are by definition open vehicles because no firm connections between the upper transverse leg of the leg Windscreen frame and the rear element are present.

For a cabriolet is out of the EP 1 510 412 A1 an extendable protective element is known, which is suitable to break the rear window of the hood. In the storage position, the rear window - as usual in convertibles - as part of the top and stored together with this.

Solved This task is done with an open passenger car, which is the Having mentioned in claim 1 features. Embodiments of the invention are the subject of the dependent claims.

Thereby, that the open, inventive passenger cars a rollover protection device with a protective element which extends from a lowered rest position to an extended one Protective position is movable, the following advantages are achieved: The movable vehicle roof does not have to be over a fixed roll bar to be moved. This comes with a lateral linkage for the vehicle roof without long and particularly curved handlebars from what increases the stability of the vehicle roof. All in all the vehicle can be designed optimized. Furthermore can be a desired storage position for the vehicle roof be achieved if the lateral linkage not on a fixed roll bar must be agreed. In addition, elaborate joining steps avoided in the shell, if no fixed roll bar is provided. Furthermore, it is advantageous that the movable protective element the rollover protection device the weight of the passenger car not in the roof area, but lower lying, especially below the waistline, what affects the vehicle's center of gravity and the balance of the motor vehicle while driving cheap effect.

Prefers is an embodiment in which in the extended Protective position, the protective element projects beyond the rear element. Thus, the shelter can be increased below the protection element become. In particular, this extended protection position can be achieved be when the rear element has a rear window. This can are broken by the extending protective element, so that the increased protective position occupied by the protective element can be. This allows the invention Housing protection element relatively far in the rear of the passenger compartment and affects the space in the passenger compartment barely. In this case, the rollover protection device on the vehicle body or the shell may be appropriate.

In order to the protective element, the rear element or a sunroof functionally reliable can break through, it has in a preferred embodiment a manipulator for this. This manipulator can for example, as a mandrel, generally as a punch-through element formed be.

Instead of the destruction of the rear window can this by the outgoing Protective element arranged releasably attached to the rear element be. This releases an opening in the rear element, so that the protective element occupy the elevated protective position can.

According to another embodiment, it can be provided that the protective element in the protective position reaches as far as the rear element when the rear element is in its normal position occupies. Thus, it is advantageously possible that the protective element supports the rear element and forms together with this the rollover protection device. In the protective position, the protective element reinforces the rear element. This is particularly advantageously possible with a rear element, which comprises at least one frame part in addition to the rear window.

In Particularly preferred embodiment is the rear element a movable trunk lid, which between an open position of his Normal position is adjustable. This is possible, that Put the vehicle roof under the boot lid when it is in its open position occupies. If the vehicle roof is stored, the boot lid is back moved back to the normal position.

at a particularly preferred embodiment is at the closed passenger car a windshield frame reinforced, for example, with an internal reinforcement executed. The extendable rollover protection element then acts with the reinforced windshield frame together such that rigid, upwardly projecting components the underlying shelter for define the vehicle occupants.

Prefers Further, an embodiment in which the vehicle roof two movable roof sections, in particular shell-like roof segments, comprises, which lie one above the other in the storage position are arranged. This results in the storage position a in the vehicle longitudinal direction short version of Vehicle roof, so that the protective element in front of or behind the stored Drive over the vehicle roof in the protective position. Prefers the vehicle roof is in the storage position behind the rollover protection device, then arranged in particular immediately behind a vehicle seat is.

In a side view is in 1 an open passenger car 1 The following is merely a car 1 referred to as. He has a structure 2 with a body 3 and various attachments 4 such as side doors, nose and tail fairings and the like. Above a waistline 5 the body 2 extends a windshield frame 6 holding a windshield 7 surrounds. The windshield frame 6 has a transverse frame leg, also referred to as upper cowl 8th , towards the rear of the vehicle 9 a between a closed position ST and a storage position AT and vice versa movable vehicle roof 10 connects, in a rear-side storage room 11 ( 3 ) can be stored in the storage position AT. At a rear end edge 12 of the vehicle roof 10 closes with its front transverse edge 13 a rear element 14 on which a rear window 15 can have. In particular, the rear element 14 movable on the body 3 stored and designed as a movable trunk lid, which is between a in 1 Normal position NP and an open position OP can be moved, this being a suitable linkage (not shown) between the rear element 14 and the body 3 is provided. The rear window 15 is provided by at least laterally provided frame parts 11 ' of the rear element 14 edged between the vehicle roof 10 and the waistline 5 extend.

In the closed position ST spans the vehicle roof 10 a passenger compartment 16 , In the storage position AT of the vehicle roof 10 is the passenger compartment 16 through a roof opening 10 ' ( 3 ) above, with the roof opening 10 ' laterally is not limited by Dachlängsholmen when the vehicle roof 10 takes the filing position. The roof opening is limited 10 ' only through the transverse frame leg 8th and the transverse edge 13 of the rear element 14 , A comparison between the 1 and 3 shows that the rear element 14 independent of the two end positions, closed position ST and storage position AT, of the vehicle roof 10 always the same normal position NP above the waistline 5 and in front of a rear cover, in particular a motor cover MD, occupies.

In the closed position ST is the vehicle roof 10 between the transverse frame leg 8th and the front transverse edge 13 of the rear element 14 , For transferring the vehicle roof 10 from the closed position ST in the storage position AT and vice versa, a lateral linkage (not shown) is provided with a linkage, which is the vehicle roof 10 movable on the body 3 holds. For storing the vehicle roof 10 will that rear element 14 from its normal position NP to its open position OP ( 2 ), so that the underlying storage space 11 is open at the top and the vehicle roof 10 can be stored in it. In this case, the vehicle roof 10 below the waistline 5 lie so that it is in 3 not visible. However, the storage position AT can be at least partially above the waistline. During the storage movement in the direction of storage position AT and vice versa passes over the vehicle roof 10 a partial opening position TE, like it 2 shows. In particular from 2 it can be seen that the vehicle roof 10 comprises two roof sections D1 and D2, which are preferably formed as dimensionally stable roof segments and the above-mentioned lateral articulation movable on the body 3 are held. The roof sections D1 and D2 lie in the storage position At identically oriented one above the other, ie, an outer skin AH of the one roof section D1 or D2 faces an inner surface ICH of the other roof section D2 or D1. In the closed position ST both roof sections D1 and D2 are in series one behind the other between the transverse frame legs 8th and the transverse edge 13 , as in 1 shown.

In the vehicle interior or passenger compartment 16 of the car 1 are one or two rows of seats 17 . 18 arranged with at least one vehicle seat per row of seats, of the vehicle seats only a backrest 19 respectively. 20 is shown. In the embodiment, the front row of seats is located 17 below the vehicle roof 10 while the back row of seats 18 at least partially below the rear element 14 is arranged.

Inside the passenger compartment 16 and especially in front of the storage room 11 is at least a rollover protection device 21 arranged behind the rear row of seats 18 , for example, approximately parallel to the backrest 20 is appropriate. The rollover protection device 21 owns according to 4 a fixed, ie by car 1 connected cassette 22 in which a movable protective element 23 is guided, which is executed here as the reverse U-shaped bracket. The movable protection element 23 could alternatively only with an upright leg, so quasi stamp-like executed, and possibly each next to a row of seats 17 . 18 to be appropriate. In 4 is the movable protection element 23 shown in a retracted or lowered rest position RS. In particular, it is provided that in the rest position RS, the protective element 23 completely in the cassette 22 is received or this only slightly surmounted. In the rest position RS is the protective element 23 Under The waistline 5 or surpasses these only slightly. In the 1 and 3 however, the protective element is 23 in a protective position SC relative to the cassette 22 moved upwards, so in particular linearly extended. Unless it is the car 1 could be a two-seater vehicle, the rollover protection 21 in an analogous way behind the front row of seats 17 be arranged, with the rear element 14 with its transverse edge 13 up to or over the backrest 19 would be enough. In the storage position AT is the vehicle roof 10 in any case before or after the rollover protection device 21 However, it prefers behind it as it does for 3 is accepted.

The rollover protection device 21 is under the rear element 14 arranged. If it is a four-seat car 1 is the rollover protection device 21 behind the second row of seats 20 in the passenger compartment or between the passenger compartment 16 and storage room 11 or in the storage room 11 placed. The lowered or retracted rest position RS of the rollover protection device 21 is - as previously described - in 4 shown. Due to the towards the vehicle rear 9 sloping line or contour of the rear element 14 would be the extension height of the protective element 23 in the protective position SC through the rear element 14 limited. Therefore, the protective element has 23 in a further embodiment of the rollover protection device 21 , especially at its upper end 24 , a manipulator 25 that makes it possible for the protective element 23 the rear element 14 , especially the rear window 15 , breaks through, and that it is the rear element 14 surmounted in the protective position SC. In a particularly preferred embodiment, this manipulator 25 realized as a tip, in particular mandrel, the extension of the protective element 23 from the rest position RS in the protective position SC on the rear window 15 meets and manipulates or manipulates them so that the rear window 15 loses strength and so on the protective element 23 can be broken. Alternatively, the protective element could 23 the rear window 15 from the rear element 14 release when it goes up to the protective position SC. The manipulator 25 would not be mandatory, but could certainly on the protective element 23 to be appropriate.

The rollover protection device 21 forms together with the reinforced windscreen frame 6 a protective device in a vehicle rollover.
