Abstract: An impact protection system is provided for a door of a motor vehicle and extends between upright door frames of a door body. On one side the impact protection system is connected with a hinge column by way of hinges and, on the other side, adjacent to a lock of the door, is connected with an additional column. The hinge column and additional column are integrated in a body structure of a body of the motor vehicle. In order to optimize this impact protection system, the lock is mounted on the latter and, in the closed condition of the door, an engaging device of the door interacts with a receiving device of a deformation device which is fastened to the additional column of the vehicle body structure.

Abstract: A door suitable for a motor vehicle is inserted in a recess of a body and includes a door body braced on upright columns of the body. The door body has an internal member and an external member and possesses frame elements bordering on the columns between which an impact protection device extends. In order to optimize this door, the external element connected to the internal element interacts with the impact protection device on an interior between the frame elements of the door body by way of a support apparatus.

Abstract: A removable roof is provided for a passenger car of the sports car type, between a windshield frame and a rollover bar system, which roof is made of a plastic material and includes an exterior wall as well as an interior wall. In order to create a highly stressable, light-weight and space-saving roof, the exterior wall as well as the interior wall are made of a high-strength plastic material and form a rigid member connection, the exterior wall and the interior wall meeting essentially only at edge zones.

Abstract: A removable roof is provided which intended for a motor vehicle passenger car, which covers roof and opening between a windshield frame and a body structure of a vehicle body which extends, for example, behind vehicle occupants seats. The removable roof is formed of a dimensionally stable material and is held in position, on the one side, by means of a form-lockingly acting fixing system and, on the other side, by means of a locking system. So that, while the mounting and demounting are simple, the roof is securely fastened to the vehicle body, the roof comprises two roof elements which are fitted together without hinges in a longitudinal center plane, each roof element cooperating with the windshield frame, by means of a first fixing device and a second fixing device of the fixing system, and with the vehicle body frame structure by means of a locking device of the locking system.

Abstract: A locking device suitable for a removable top of a motor vehicle, which extends between fixed structures, such as a windshield frame and an anti-roll bar of a vehicle body, includes a locking element on the roof, which works together with a mounting that is attached, for example, to the anti-roll bar, is directed towards the passenger compartment, and is provided in a fastening plate. The fastening plate, which may be attached to the anti-roll bar, includes a cover element, which can be displaced from a first position into a second position covering the mounting of the fastening plate and vice versa.

Abstract: A lock suited for a removable roof of a motor vehicle, especially a passenger car, is held against a fixed structural part such as a rollover bar of a body of the motor vehicle by way of a locking member of the lock. The lock has a first actuating element and a second actuating element, and the first actuating element is surrounded by the second actuating element surface-flush. The actuating elements act in conjunction with each other such that only upon operating the first actuating element can the second actuating element be moved from a closed position into an open position. To ensure that the lock has a simple design and good functionality while requiring little space, the first actuating element effects the open position of the lock with a lifting motion and the second actuating element with a rotary motion. The locking member of the lock is connected torsion-resistant by way of a bearing shaft to the second actuating element.

Abstract: A removable roof is provided for a motor vehicle, particularly a passenger car, and covers an opening between a windshield frame and a body frame structure of a vehicle body extending, for example, behind vehicle occupant seats. The roof comprises a dimensionally stable material and cooperates by means of a form-lockingly operating fixing system with the windshield frame. For optimizing the connection of the roof with the windshield frame, the fixing system of the roof has a first fixing device and a second fixing device. The two fixing devices are arranged offset with respect to one another in the vertical direction of the vehicle by a distance measurement and are caused to engage by means of a movement of the roof in the driving direction.

Abstract: A removable roof intended for a motor vehicle, particularly a passenger car, covers an opening between a windshield frame and a body frame structure of a body of the passenger car extending, for example, behind vehicle occupant seats. On the one hand, the roof is held in position by a form-lockingly operating fixing system and, on the other hand, by a locking system, which locking system is operative between the roof and the vehicle body frame structure constructed as a rollover bar system. In order to advantageously fasten the roof by the fixing system and the locking system on the windshield frame and the rollover bar system respectively, the locking system has at least one locking device cooperating with the rollover bar system and including an operating device with a locking pin which engages in a closing crank.

Abstract: This removable roof, which is suited for a motor vehicle such as a passenger car, overarches a passenger space in a body of the passenger car and is held on fixed body structures of the body. The roof is provided with at least one locking device, is made of dimensionally rigid material, and includes two roof elements assembled in a median longitudinal plane of the passenger car. For optimization of the roof, each roof element has a locking apparatus and cooperates with a bracing apparatus which counteracts moments on a bracing apparatus lying on one of the fixed body structures, such as a roll bar device, upon actuation of a locking part of the locking apparatus to which a boundary wall of the roof element running adjacent to the locking apparatus is exposed.

Abstract: A removable roof designed for a motor vehicle can be inserted into a stowage space of a body of the motor vehicle in a state detached from the body of the motor vehicle and is held in position using receptacles and holding devices. In order to optimize accommodation, two roof elements, which are separable on a median longitudinal plane of the body, are fixed in position, superposed as a first roof element and as a second roof element, into the receptacles of the stowage space using holding devices.

Abstract: A body of a motor vehicle, particularly a passenger car of the sports car type, equipped with a windshield frame, a rollover bar system and a removable roof covering an area between the windshield frame and the rollover bar system. The roof on one side follows a convex shaping course of the windshield frame and, on the other side, follows a shaping course of the rollover bar system such that, viewed in the longitudinal direction of the passenger car, the roof has two lateral roof sections and a center roof section which extends between the lateral roof sections in the manner of a crease-type indentation shaped in the direction of the vehicle occupant compartment.
