Abstract:
A connecting rod is provided with a bent portion in a substantially middle part thereof so that a lower section of the connecting rod below the substantially middle part in a vertical direction may be inclined, with respect to the longitudinal direction of a guide rail, toward a center of an opening, and at the same time, an upper section of the connecting rod above the substantially middle part may be substantially in parallel to the longitudinal direction of the guide rail and offset from a side face of the guide rail directed to the center of the opening toward the center of the opening, when the connecting rod is in a position corresponding to a closed position of an open/close member.

Abstract:
When a slide door stops at an intermediate position over a protection action time start time (Tβ), an electric motor is operated in closing direction in low driving force mode. When the move speed (Vc) of the slide door is a movable speed (Vα) or higher, the slide door is moved to its fully closed position by automatic closing action, and an electromagnetic clutch is disconnected. On the other hand, when the move speed (Vc) of the slide door is not made to reach the movable speed (Vα) or higher over a speed judgment time (Tj), the electric motor is operated in closing direction in the low driving force mode, and when the move speed (Vo) of the slide door is made to reach the movable speed (Vα) or higher, the slide door is automatically opened. Further, when the move speed (Vo) of the slide door is made to reach the movable speed (Vα) or higher for the speed judgment time (Tj), the electric motor is stopped, and the electromagnetic clutch is made into its disconnected status.
Abstract:
An electromechanical strut using an inline motor coupled to an inline planetary gear that are both mounted in the lower housing. The motor-gear assembly drives a worm gear and nut screw in the upper housing, extending or retracting an extensible shaft. Additionally, a power spring mounted coaxially around the worm gear provides a mechanical counterbalance to the weight of a lift gate on the shaft. As the shaft extends, the power spring uncoils, assisting the motor-gear assembly in raising the lift gate. Retracting the shaft recoils the spring, storing potential energy. Thus, a lower torque motor-gear assembly can be used, reducing the diameter of the lower housing. Preferably, the power spring can also drive the power screw to extend the strut even when the motor-gear assembly is not engaged.
Abstract:
A rear gate is constructed to be opened and closed by a driving unit installed on a vehicle body side, and the driving unit is constructed to have a motor which can rotate both in normal and reverse directions, a gearbox to which a pinion is pivotally attached for reducing the rotating speed of the motor for output, and a rack adapted to reciprocate in directions normal to an axial direction of a hinge shaft by virtue of the rotation of the pinion and connected to the rear gate at one end thereof. An electromagnetic clutch for connecting and disconnecting a power transmission path between an output shaft of the motor and the pinion is provided in the interior of the gearbox, so that the rack is disposed above or below the gearbox at a position directly above or below the clutch.
Abstract:
A drive mechanism is provided for a door operator, comprising a drive member and a driven member. The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation in a direction toward an adjacent driven surface causes rotation of the driven member for powered opening of the door from the closed position to the open position. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually from the closed position and allowed to close.
Abstract:
Methods and apparatus are provided for reducing the occurrence of vehicle door bumps against an adjacent object facing the door. The apparatus comprises one or more distance sensors mounted on the vehicle for measuring distance D from the door to the object, a brake for inhibiting outward movement of the door toward the object, a warning system and a controller coupled to the distance sensors, warning system and brake for applying the brake to inhibit further outward movement of the door when D≦D(MIN), a predetermined minimum distance away from the object. In a preferred embodiment, a first driver warning is activated when the initial door-to-object spacing D(INIT)≦D(SAFE), the maximum outward door reach. A second warning is desirably added when the door begins moving toward the object or has reached about (D(INIT))/2 and a third warning is activated when the brake is engaged.
Abstract:
A drive arrangement for a motor vehicle door or hatch which can be moved by a motor with a planet gear and a brake device with a brake. The brake device has a brake drive which is separate from the drive which drives the drive shaft and the brake is able to be moved at least from one of two positions into the other of the two positions by the brake drive. The brake can be an arc-shaped clip pivotally supported by a pivot axle with an inner periphery which is matched to an outer periphery of an element of the planet gear. The brake can be combined with the brake drive as an eddy current brake or can be operated by a further gearing or use of a permanent magnet with which an electromagnet is able to interact.
Abstract:
In a foreign material detector for a sliding door, a pressure sensor is disposed being offset toward a vehicle interior side and a substantial vehicle front side of a hem and being offset toward a substantial vehicle exterior side with respect to a position supported by a bracket as well, in order for the foreign material to be detected, even though a direction of a reaction force effected from a foreign material is tilted and intersected with respect to a moving direction of the sliding door.
Abstract:
The force from a drive rod driven by an electric motor is transmitted via a link arm pivotally linked to the drive rod and a back door. When the back door is operated in opening direction, the link arm is supported by open-side support sliders and the acting direction of the force applied to the link arm by the drive rod is shifted to the opening direction of the back door. When the back door is operated in dosing direction, the link arm is supported by closed-side support slider and a closed-side support roller and the acting direction of the force applied to the link arm by the drive rod is shifted to the closing direction of the back door. The open-side and closed side support sliders are pressed against the link arm by leaf spring members so that the link arm is prevented from oscillating between the sliders.
