Abstract: In order to improve a carrier device for motor vehicles which is designed to support loads such that the loads acting on it can be detected, it is suggested that the carrier device be provided at the least with a first sensor at a first installation point and with a second sensor at a second installation point, that a section of the carrier device be located between the installation points, its deformations caused by a load being detected by the sensors at least in part and that an evaluation unit be provided which records measurement values of the sensors and determines a borne load from them.

Abstract: For a trailer coupling, the fixing unit has a stationary first toothed segment which is fixedly connected to the pivot bearing base. A first toothed segment which in the working position is connected to the pivot element in a rotationally fixed manner and pivots together with same and is engageable by displacing the pivot element from the pivot position into the fixed position, and is disengageable by displacing the pivot element from the fixed position into the pivot position.

Abstract: In order to improve a support unit for motor vehicles comprising a supporting structure mounted on a rear end portion of the motor vehicle a sensor unit is provided for detecting forces acting on the supporting structure and elastically deforming the same. The sensor unit is provided with a sensor base, comprising two fixation regions which are spaced apart and can be fixed to mounting regions of an elastically deformable supporting structure portion. A transformation region disposed between the fixation regions mechanically converts the movements of the mounting regions, and thus also of the fixation regions relative to one another. Movements are generated by the elastic deformation of the supporting structure portion, into a movement of measuring points of the transformation region relative to one another. The movement of the measuring points can be detected by the sensor unit.

Abstract: In a wind deflector for installation in a vehicle roof in a front area, comprising a wind deflector body which extends in a direction of extension transversely to a direction of travel, a lifting device, with which the wind deflector body can be moved between a position retracted into the vehicle roof and a position extended out of the vehicle roof and projecting beyond a contour of the upper side of the vehicle roof and thus deflecting wind, wherein the lifting device has at least one lifting unit with a mounting base and a lifting arm which is mounted with a lifting arm bearing for pivoting about a first pivot axis relative to the mounting base and engages on the wind deflector body at an end located opposite the lifting arm bearing, in order to achieve a reliable movability of the wind deflector body with devices which are as mechanically simple as possible it is suggested that an actuating unit which is supported on the mounting base and engages on the lifting arm be provided for moving the lifting arm an

Abstract: A carrier device for mounting at a rear side of a body of a vehicle, said carrier device comprising, a receiving element, adapted to be fixed to the body of said vehicle, said receiving element comprising a receiving channel with an insert opening, a carrier element, adapted to be releaseably received in said receiving element in a mounted position, said carrier element being insertable into said receiving channel to arrive at its mounted position by movement through said insert opening in direction parallel to a longitudinal direction of said receiving channel, a locking unit for locking said carrier element in said mounted position in said receiving element, a key unit comprising a first key element arranged on said receiving element and a second key element arranged on said carrier element said first and second key elements cooperating in a keying position of said carrier element in order to only allow said carrier element provided with said second key element to arrive at the mounted position when inserte
