The unit (1) is further provided with coupling means (56), which can be selectively activated for coupling together the actuator (22) and the actuating mechanism (21) so as to enable opening of the door (2) via the actuator (22) itself.
Abstract:
A drive system for swiveling a panel of a vehicle about a swivel axis includes a reversible drive motor, a rotor which can be driven to rotate about an axis of rotation by the drive motor, and a coil through which current can flow to produce an axial magnetic field, the coil being arranged coaxially to the axis of rotation. An armature arranged to move axially with respect to the rotor and the coil can be moved axially into contact with the rotor to produce an interlocking connection or a friction connection between the rotor and the armature. A drive wheel is arranged to rotate with the armature via a drive train, the drive wheel being arranged to swivel the panel.
Abstract:
An opening and closing member control apparatus includes: an open-command receiving portion for receiving a first open command of a first open and close command inputting member and a second open command of a second open and close command inputting member, which performs a second open command input and a second close command input by a unique operation thereof, a close-command receiving portion for receiving a first close command of the first open and close command inputting member and a second close command of the second open and close command inputting member, and a controlling portion for performing an opening operation and a closing operation of an opening and closing member based on a condition of the opening and closing member, in response to the unique operation of the second open and close command inputting member.
Abstract:
A device for automatically controlling a slide door for a vehicle, wherein the slide door is adapted to open and close along a guide track installed in a vehicle body, the device having a door drive device, a motor load detection device, a door position detection device adapted to detect a position of the slide door guided by the guide track within a range from a position where the slide door is fully opened to a position where the slide door is fully closed, a door speed detection device, a memory device adapted to store the motor load at each position of the slide door of the vehicle standing at a horizontal level, and a motor control device adapted to automatically control power supplied to the motor for moving the slide door based on a difference between a detected motor load and a stored motor load at a corresponding position
Abstract:
An automatically opening/closing apparatus for vehicle of rack-and-pinion type is reduced in size and weight. The automatically opening/closing apparatus for vehicle is automatically opened/closed, by transmitting rotation of an electric motor to a back door through a drive power transmitting mechanism comprising a pinion and a rack. The rack is supported linearly reciprocably by a slide mechanism comprising a slide block and a guide rail. The slide block is formed to be sufficiently short to the entire length of the rack and the guide rail is accordingly formed to be short. Further, the rack is provided with a groove portion, and a holding member contacting with a holding face is disposed in the groove portion. Then, an interval between the rack and the opinion is maintained by the holding member, whereby engagement of the pinion therewith is ensured.
Abstract:
A cable drive unit for opening and closing a sliding door on a vehicle (not shown) has a cup-shaped front drum having a helical front cable groove and a rear cup-shaped drum having a helical rear cable groove. The front drum is rotated about a longitudinal axis in a first direction to open the sliding door. The rear drum is partially nested in the front drum and rotated about the longitudinal axis in an opposite direction to close the sliding door. The front drum and the rear drum are drivingly connected to each other via a tension spring that biases the front drum and the rear drum in opposite directions when in tension. The front and rear drums are rotated by a concentric clutch that is nested in the rear drum. The clutch includes a drive member that is drivingly connected to the front drum via a first lost motion connection and drivingly connected to the rear drum via a second lost motion connection. The first drum has an arcuate slot forming part of the first lost motion connection, the rear drum has an arcuate slot forming part of the second lost motion connection, and the drive member has a tab that projects through both arcuate slots to form part of the first lost motion connection and part of the second lost motion connection.
Abstract:
A lock latch mechanism disposed within a powered locking device of a transit vehicle door system for maintaining a lock lever in an unlock position without the aid of the lock actuator. The lock latch mechanism includes a lock latch lever biased for engagement with an unlock cam through the use of a bias spring. The lock latch mechanism further includes a reset lever assembly engaging such lock latch lever during the door closing motion to allow movement of the lock lever form such unlocking position into such locking position to maintain at least one door of the transit vehicle in the fully closed and lock position. A manual release lever is provided to move the lock lever from such locking position into such unlocking position enabling the lock latch mechanism to maintain the lock lever in such unlocked position.
Abstract:
A driving apparatus for a movable member of an automobile comprises a housing, a dram for driving the movable member, the dram being rotatably supported on the housing, and a clutch for selectively transmitting a driving torque to the dram, wherein the clutch is accommodated in a space of the dram.
Abstract:
A fire door control system permits user input during regular use and during alarm conditions. The system utilizes primary and secondary power sources and incorporates a variety of preventive safeguards assuring that functionality of the fire door control system will not be lost. The system utilizes primary power when possible in all alarm conditions. However, during alarm conditions when primary power is lost or when a hand crank hoist remains dangerously engaged, the system is bumplessly connected to a secondary power source and a fire door of the system is closed with the aid of a clutch that directly connects the drive input with an axle that supports the fire door. The clutch pulses on and off to control the descent of the door. The system includes an electronic controller for coordinating the operation of elements of the system and for implementing a method of controlling a fire door system.
Abstract:
A rear gate opening and closing apparatus includes a gas stay for biasing a rear gate in an opening direction, a motor for actuating to open or close the rear gate, a clutch for connecting or disconnecting the motor with the rear gate, an encoder for detecting the position of the rear gate, an operating switch for operating an opening and closing motion of the rear gate, and a control means for controlling the motor and clutch to automatically open and close the rear gate. The opening and closing speed of the rear gate is controlled based on a detection signal of the encoder.
