Abstract: A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle frame and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a bracket that is secured to the vehicle body for supporting several parts including a reversible electric motor, a gear train, a rack and a cradle that are mounted on the bracket. The electric motor drives the rack via an the output gear of the gear train that has an axis. The rack slides in the cradle which is pivotally mounted on bracket so that cradle pivots about the axis of the output gear to hold the teeth of the rack in engagement with the teeth of the output gear to accommodate rocking movement of rack as it moves from a retracted position to an extended position. An arcuate track that is fixed to the vehicle body, and an arcuate link slides in the arcuate track. The arcuate link has an inboard end that is pivotally connected to an end of the rack and an outboard end that is pivotally connected to the liftgate.

Abstract: Constant balance of a varying load, particularly a window shade or blind, is maintained by providing a lifting force, preferably from a spring, through a mediating mechanism including a variable pitch screw arrangement, such that the mechanical advantage of the mediating mechanism changes to allow the continuously decreasing spring force to apply an appropriate lifting force at all times. The variable pitch screw preferably takes the form of a twisted bar.

Abstract: A multiple spring counterbalance includes a torsion spring and a tension spring for exerting a combined lifting force on a window sash. A spiral rod is threadably engaged with a follower nut for converting a torque applied by the torsion spring into a lifting force on the window sash. The spiral rod has a pitch that is varied along one part of its length to produce a substantially constant combined lifting force throughout most of a range of sash travel between a lowered position and an intermediate position. However, the pitch is further varied along another part of the length of the spiral member to produce a larger combined lifting force within a remaining portion of the range of sash travel from the intermediate position to the raised position.

Abstract: A swinging-sliding door for vehicles, particularly for passenger vehicles, includes two door leaves positioned outside and within the wall of the vehicle in a closed state. For the door, a driving device for operating the door leaves includes pivotable, roller carrying levers which swing the door leaves from the closed position into a ready-to-open position; in addition, the driving device exerts a reaction force onto the pivotable roller carrying levers which, in closed position, results in locking them, a driving device includes a single electro-motor and gearing unit positioned laterally above the opening of the door, further having a case and a driving pulley, a traction belt is guided through a deflection pulley and couples the drive pulley to the door leaves via the roller carrying levers; the case has a flange carrying an eccentric control pin engaging a control lever fastened to a door post carrying the pivotable roller-carrying lever, and the control pin in a door closing position being held in a dead center position in a curved contour of the control lever so that the door is safely locked and can neither be opened manually nor by forces of the wind.

Abstract: An improved straight line motion gate mechanism which translates gate position to an open/closed position without any perceptible vertical motion and without any moving contact with either the ground or the use of a track. The gate may assume a wide range of widths and the mechanism may be self locking in the closed and open positions. A very small vertical motion of the mechanism provides for minimal input energy requirements and is relatively insensitive to gate weight.
