A support structure for a motor vehicle with a first connecting section, a second connecting section and a deformation section, which is arranged between the first connecting section and the second connecting section. The deformation section is provided in its lengthwise dimension with a recess formed from a middle web and legs joined to it by connecting regions. The deformation section is fashioned as a single piece and a) the wall thickness in the connecting regions is at least partly along the lengthwise dimension of the deformation section at least 20% larger than the wall thickness of the middle web and/or the legs and/or b) the ends of the legs have a wall thickness which for at least a portion of the lengthwise dimension of the deformation section is at least 20% greater than the wall thickness of the middle web and/or the legs.

Support structure for a motor vehicle

A front-end structure of a motor vehicle includes a transverse member and two crash boxes. In addition a transverse reinforcement member is arranged according to the invention, wherein the transverse reinforcement member is supported via coupling beams on a subframe.

Bumper system for a motor vehicle with a cross member which is arranged cross to longitudinal members and having a top side, a bottom side, a front side and a back side and with at least one means to ensure adequate energy impact into the cross membercharacterized in that at least one means on the top side and/or on the bottom side of the cross member is arranged in that way that it is pointing away from the cross member wherein air can stream at least partially through a region above and/or beneath the cross member during driving of the motor vehicle.

Bumper system for a vehicle

A bumper system for a motor vehicle includes a bumper cross member which is arranged transversely to a travel direction and has two attachment zones for connection to two side rails arranged in parallel relationship to the travel direction. The bumper cross member has a center portion extending between the attachment zones and two end zones to close off the bumper cross member to vehicle sides. A deformation element is arranged behind each of the end zones and constructed to support in the event of a head-on collision with slight overlap the end zone which undergoes a buckling as a result of the head-on collision. At least one belt element at least partly surrounds a circumference of the deformation element and is secured to at least one of the side rails.

A convertible vehicle with a roof can be folded down under a cover part in a rear section of the vehicle. The cover part can be opened in a first direction to release an opening for luggage and in a second direction to release an opening for the roof. The vehicle includes a movement mechanism to hold the cover part and further includes at least one multi-link chain. The multi-link chain includes a plurality of hinges for the movement of the cover part. At least one of the plurality of hinges is held in an idle state when the cover part is opened in the first direction and the second direction.

The present invention relates to a roll-over protection device for a motor vehicle, particularly for a convertible, comprising a roll bar (). This roll bar is provided with an at least nearly U-shaped design having a transverse yoke () and lateral limbs (A,B) while leaving a loading opening () unobstructed, and extending such that it essentially spans the width of the vehicle. The lateral limbs (A,B) can be displaced along fixed guiding devices () in order to transfer the roll bar () out of a lowered non-operational position and into a raised supporting position. To this end, a central retaining and activating device () for the roll bar (), said device being controlled by an actuator (), is provided and/or a device () that synchronizes the displacement of the limbs (A,B) of the roll bar () along the guiding devices () is provided.

Roll-over protection device for a motor vehicle

A vehicle roof structure (), which has at least one rear-side convertible top compartment lid () and a rigid roof part () movable between an opened- and a closed position, which roof part () extends in the closed position between a windshield frame () of the vehicle and the convertible top compartment lid () and in the opened position is stored in a space underneath the convertible top compartment lid (), is movable between the closed position and the opened position by a linkage mechanism () and is additionally provided with at least one guide device (), with which the roof part () is in contact during at least one portion of its movement path between the opened- and closed position and which effects a directional change of the movement path of the roof part () when it arrives in contact with the roof part.
