Definitions

  • the present invention relates to an opening and closing system for motor vehicles, more particularly to an automatic opening and closing system having an anti-jamming function.
  • Sliding doors are increasingly used in motor vehicles, especially in small transporters and mini-vans. Automatic opening and closing sliding doors are increasingly being used. Sliding doors are characterized by comparatively high masses, so that braking devices for braking the sliding door can be provided in order to achieve short braking times. Such braking devices can also be used as door retainers, for example in an open position of the sliding door on sloping terrain.
  • DE 31 34 093 A1 discloses a sliding door which is fixed to the guide rail by means of a longitudinally movable armature in a guide rail, wherein a brake for braking the movement of the armature in the guide rail, a release device for releasing the brake and a device for automatically releasing the brake immediately before are provided for closing the sliding door.
  • the door handle can also be designed as a release lever for releasing the brake.
  • a brake shoe is permanently biased against a support roller which engages the guide rail.
  • the door handle To open the sliding door, the door handle must be operated together with the release handle, so that the brake shoe is no longer resting against the support roller.
  • the closing of the sliding door requires actuation of the unlocking lever.
  • a reliable anti-trap protection can hardly be realized, since it is not guaranteed that the release lever is released quickly enough in the event of a pinching condition.
  • DE 198 03 709 A1 discloses an automatic opening and closing system for a vehicle sliding door, in which a holding force for holding the sliding door in a predetermined position in all operating conditions of the vehicle is to be kept constant, that is, even with inclined ground and in the event of a voltage drop of the electrical system.
  • a specially designed control circuit is provided which forcibly operates a clutch device upon a fall in a power supply voltage supplied to the control device.
  • An anti-trap function is not disclosed.
  • DE 196 81 592 B4 discloses a device for automatically controlling the opening and closing of a motor vehicle sliding door.
  • the apparatus comprises door position detecting means for detecting the position of the sliding door guided by the guide rail, door speed detecting means for measuring the moving speed of the sliding door, and motor control means for controlling the power supplied to the motor based on the difference between the stored engine load and the engine load for moving the sliding door the current position is recorded.
  • an anti-jamming function in which it is judged based on a load resistance component whether jamming state exists or not. If a pinching condition is detected, the drive is braked and / or reversed.
  • US 2004/0155617 A1 discloses a Einklemumm fertilsvoriques for an opening-closing element in the form of a motor vehicle sliding door.
  • the sliding door is a drive motor, a motion transmitting member, a deforming member configured to be deformed via the motion transmitting member in accordance with the force applied by the sliding door in an opening-closing operation, a strain gauge mounted on the deforming member, and a control mechanism associated with detecting trapping of a foreign object.
  • An elongation of the strain gauge corresponding to the deformation of the deformation element is converted into an electrical signal, on the basis of which the control mechanism then outputs an electrical signal indicative of a pinching condition. This triggers a reversing of the drive motor to decelerate the sliding door and reverse its direction of movement.
  • a bias of a braking element in a braking or blocking position is not disclosed.
  • US 2002/0189168 A1 discloses a motor vehicle hinged door having an anti-jamming function that actively activates a brake member to engage it with an adjustment member of the hinged door and thus decelerate it. This is done hydraulically, pneumatically, electrically or by means of springs. However, a bias of a braking element in a braking or blocking position is not disclosed.
  • US 2004/0046418 A1 discloses a drive having a force transmitting member and a braking member biased to a braking or blocking position and adjusted against the biasing force from the braking or blocking position to a release position when the drive mechanism transmits the biasing force and an interruption of the force acting on the Kraflübertragungskette adjusting force not available.
  • EP 0 200 115 A2 discloses a further opening and closing system for a motor vehicle sliding door, wherein a braking device comprises a biased braking element, and is designed so that it is automatically activated in an interruption or a decrease in the force acting on at least one member of the power transmission chain adjusting the braking device.

Because the braking device is automatically activated, the comparatively heavy sliding door can be decelerated quickly and without a long time delay. Thus, the risk of trapping mechanical obstacles in the sliding path of the sliding door and the risk of collisions of the sliding door with mechanical obstacles can be advantageously reduced.
  • the opening and closing system can be used both in an exclusively manually operable sliding door as well as in an optionally manually or automatically operable sliding door, ie in a sliding door, which is assigned its own drive mechanism, with a Switzerlandseilsystem to relocate the sliding door.

  • the strength of the adjusting force for moving the sliding door can signal the pinching or collision state or the pre-crash situation.
  • Elaborate further detection means for detecting a pinching condition and / or mechanical obstacles in the displacement path of the sliding door are thus not absolutely necessary.
  • the braking device may be directly or indirectly coupled to a drive train for driving the sliding door.
  • a Seillose can be used according to the invention for automatic activation of the braking device.
  • the braking device comprises at least one braking element which is biased into a braking or blocking position, wherein the braking device is coupled to the force transmission element, that the braking element is adjusted against the biasing force from the braking or blocking position to a release or friction position when the Drive mechanism transmits the adjustment and an interruption or a decrease in the force acting on the power transmission chain adjusting force is not present.
  • the power transmission element comprises a door-opening cable or a door-closing cable of a cable mechanism for opening and closing the sliding door and the brake element is automatically adjusted to the braking or blocking position when a tensile force of the door opening or door-closing cable is interrupted or subsides under falls below a predefinable value.
  • the braking device is thus directly coupled to the cable which transmits the adjustment force to the sliding door, so that the braking device can be activated even more quickly in the event that a pinching or collision state or a pre-crash situation is signaled or detected.
  • the aforementioned value can be specified by the mechanical design of the braking device, for example a cable system for actuating the same, or by a biasing means, for example a spring.

  • the pinching state detection means can detect or detect the obstacles electronically, opto-electronically or mechanically. For example, it can be concluded from the driving force, the rotational speed or comparable parameters of a drive motor and / or the drive system to a pinching or collision state.
  • the signals of the pinching state detection means can also be evaluated electronically, for example, by a control unit which is coupled to the drive motor.
  • the pinching state detection means may be formed as a switching or contact strip arranged along an edge of the sliding door.

  • the self-reinforcing braking state is taken in particular immediately before reaching an end position of the sliding door (fully closed or open position of the sliding door), so that a soft-stop function and a quiet closing of the sliding door can be achieved. This allows an overall lighter design of the sliding door system, since the invention lower impulse forces act, especially in the case of a pinching or collision condition.
