A drive device for a pivotable vehicle flap includes a flap part associated with the vehicle flap, a body part associated with a vehicle body and a hinge arrangement which hingedly connects the flap part and the body part. The hinge arrangement allows the flap part to be pivoted about a first axis of rotation for opening and closing the vehicle flap and about a second axis of rotation for raising the vehicle flap into a pedestrian protection position. The drive device further includes a first actuator for opening and closing the vehicle flap in normal operation, a second actuator for raising the vehicle flap into a pedestrian protection position and a coupling device for coupling the first actuator to one of the flap part and the vehicle flap, including a fastening part which is fixedly connected to the one of the flap part and the vehicle flap. The coupling device includes at least one first lever coupled to the first actuator. During normal operation of the coupling device, the first lever is releasably secured against rotation relative to the fastening part via a mechanical securing element.

A scissor drive includes two legs which can be pivoted relative to one another about a pivot axis, each having a longitudinal axis and designed to be connected to an external component, and a motor/gear assembly that drives the relative pivoting movement of the two legs. The first leg includes a housing that is hollow at least in portions, a cavity defined in the hollow housing extending at least in portions along the longitudinal axis of the first leg, and the motor/gear assembly being received in the housing of the first leg at least in portions in the portion of the cavity that extends along the longitudinal axis of the first leg.

A drive arrangement for a door device which includes a door member. The drive arrangement includes a door shaft, a driven shaft which is operatively connected to the door shaft, a transmission arrangement which drives the door shaft, and at least one electric motor which is coupled to the transmission arrangement to move the door member of the door device from a closed state to an open state and vice versa. The at least one electric motor has at least one eccentric drive shaft. The transmission arrangement includes an eccentric gear transmission which has at least two orbiting toothed disks, each of which have an internal toothing. The at least two orbiting toothed disks are driven by the at least one eccentric drive shaft of the at least one electric motor, and, via the internal toothing, engage with the driven shaft.

An automatic door opening apparatus for a vehicle. Two and three hinge joint embodiments with motors at each hinge joint to control motion of the door opening apparatus relative to the vehicle at that hinge joint. The motors are individually programmable to customize the door opening apparatus and movement to different vehicles. The motors can be in alignment or out-of-alignment with the hinge joints, but in either case the motor controls motion of the hinged components at the associated hinge joint. When a motor is out-of-alignment with the hinge joint it controls, then pulley wheels and belts can be used to connect the motor to the hinge joint. The door opening apparatus can also include a floor track, and a door arm that connects the door to the floor track.

A system for detecting the movement conditions of the leaf closing a barrier, the leaf being able to occlude a delimited opening or passage and in which the leaf itself is moved by a motor whose rotation shaft is associated with a motion transmission mechanism to the leaf. On the motor is present a first device for measuring the rotation of the rotation shaft, and a second measuring device is associated with a second rotation shaft being connected to the first shaft by a reduction gear with a reduction ratio that is non-integer.
