In a guiding device for a vertically adjustable window pane of vehicle doors, two holding parts, which each have an upper and a lower sliding block and are spaced away from one another, are provided at a lower edge of the window pane, these holding parts being in operative connection with U-profiled tracks of guide rails mounted in the door body. So that, for framelessly guided window panes having a pronounced lateral drop with respect to the door body located underneath, a guiding device is provided which, while it has a simple construction, ensures a functionally appropriate holding of the window pane in all positions, two tracks are constructed at each guide rail. The upper sliding block interacts with the first track, and the lower sliding block interacts with the second track. The tracks of one guide rail and the two sliding blocks of each holding piece are arranged at opposite longitudinal sides of a common connecting web of the guide rail extending transversely to the longitudinal direction of the vehicle.

A motor vehicle door lock is equipped for cooperation with a central locking system able to lock all doors of a vehicle from a single control. The lock also has a pull closed mechanism which is driven by the same motor driving the locking elements in response to a signal from the central locking system. The pull closed mechanism cooperates with a fork latch for bringing the fork latch from a preliminary latching position into a main or final latching position, whereby door slamming for properly closing a vehicle door is not necessary. It is now sufficient if the user closes the door so that the fork latch is in its preliminary latching position since the present invention mechanism will then close the vehicle door completely.

A floor group for a vehicle, especially for a motor vehicle includes a tunnel arranged in the floor center and extending in the vehicle longitudinal direction, whereby power plant parts and at least one line for the heating and/or ventilation of the motor vehicle are provided inside or adjacent the tunnel and the tunnel is closed off in the direction toward the road surface by a cover element. In order to so construct a line for the heating and/or ventilation which is arranged adjacent a tunnel that together with a simple construction it can be assembled and disassembled with low expenditure, the line is construcuted in one piece with the cover element at least over a partial area of its longitudinal extent.

A control mechanism for a door of a motor vehicle is described that is actuated via an inside and outside handle and comprises a piston-cylinder unit arranged between a door post and the vehicle door. It has a piston provided with passage openings for a pressure medium, the piston interacting with an interior valve that separates two working chambers of the cylinder from one another. The control mechanism is equipped with a blocking valve controlling the medium flow, this blocking valve being arranged in a control circuit connecting the two working chambers of the cylinder, acting against the flow direction. This blocking valve, via a control element at a door handle, can be controlled in such a way that the door is blocked in at least one intermediate position. The cylinder has at least one overflow duct between the two working chambers, the flow-through of which is controlled by the piston of the unit. The duct extends over an area into which the piston dips, up to a door opening angle of about 30.degree., during the initial opening of the door from the closed position. This opens the duct between the working chambers and an unhindered opening of the door becomes possible without an actuating of the door handle.

Adjusting device for a vehicle door

The door system for a motor vehicle comprises essentially a basic frame and an interior and an exterior part of the door. Between these parts, installation aggregates are held at a cross member connected with the basic frame. A first door subassembly comprises a pre-assembled basic body consisting of carriers and column parts (door frame, cross member, hinge column, lock post, upper exterior door part, door shaft carrier); the individual parts of said basic body are connected with one another in a material-locking way. They form a one-piece carrying structure that is open to the interior and exterior side of the door for the mounting of installation aggregates located on the inside (window control mechanism, window). This carrying structure, via a second, detachably fastened subassembly consisting of an interior part of the door and a lower exterior part of the door, is enclosed in an encapsulating way on the exterior side and on the interior side. The interior part of the door consists of a plastic shell that is detachably connected with the lower exterior part of the door that also consists of plastic. The exterior part of the door is constructed to be divided in an approximately horizontal longitudinal plane, the upper exterior part of the door being an integrated undetachable component of the basic body, and the lower exterior part of the door being detachably fastened, via a holding device, at the upper exterior part of the door.

Door system for motor vehicles

A control mechanism for a door of a motor vehicle is suggested that is coupled at a door post on the side of the body so that it can be swung, is actuated via an inside and outside handle and comprises a piston-cylinder unit arranged between the door post and the vehicle door. The unit has a piston provided with passage openings for a pressure medium, the piston interacting with an interior valve that separates two working chamber of the cylinders from one another. The mechanism has an exterior blocking valve controlling the medium flow, this blocking valve being arranged in a control circuit connecting the two working chambers of the cylinder, acting against the flow direction. The blocking valve is controlled by a door handle in such a way that the door can be blocked in at least one intermediate position. The interior valve is held on the piston under the tension of a spring in such a way that when the vehicle door is opened, the passage openings are closed, and when the vehicle door is closed, the passage openings are passable for the medium. The blocking valve is controlled in such a way that, when the door handle is actuated, it takes up a release position, and when the door handle is not actuated, it takes up a closing position in the control circuit.

A reinforced support member structure for a front part of a motor vehicle is described which, in a wall of the wheel housing of the motor vehicle body, has an opening for cooling air. This wall of the wheel housing is delimited by an upper and a lower side bearer member, in which case the members are connected with a floor, a transverse wall as well as a front bearer cross member. They form a spatial frame system at which a wheel guiding member, in particular a lower wishbone, is held in a supported manner. The lower side bearer member of the floor, in the corner area of the opening for cooling air, is supplemented by a reinforcing unit which connects to the transverse wall and the wall of the wheel housing. It includes support sections that are combined into a structural unit, said support sections forming a U-profile-shaped rigid swinging arm receiving means.

Vehicle body support structure

A body structure in which a transverse wall, that bounds an end of a vehicle passenger compartment, is extended to fender walls and is provided with shock absorber mounts, two upper and lower longitudinal bearers and a floor plate being attached to the transverse wall and the fender walls. To provide high rigidity, the top of the transverse wall has a parallel reinforcing element which interconnects opposite shock absorber mounts and the upper longitudinal bearers. At the bottom of the transverse wall, there is provided a frame system consisting of hollow members formed by the transverse wall and the bottom plate, and by reinforcing elements connecting the longitudinal bearers to the floor plate and a support element.

Passenger car body structure

A passenger car is provided with a body wall which preferably limits the engine space and consists of a frame system comprising an upper transverse member and a lower transverse member, the frame system being attached to fender walls and longitudinal supports. To attach unit mounts to the body end wall and satisfactorily absorb and transmit loads to the fender walls or the longitudinal supports, the frame system comprises an upper transverse member, a lower transverse member, and flanged vertical metal plates joined to a transverse wall at a distance from the median longitudinal plane of the vehicle, and the lower transverse member is connected by reinforcing elements to the higher level longitudinal supports of the fender walls.
