Definitions

  • the invention relates to an apparatus and a method to open and close a moving part after the Genre of independent claims.
  • DE 199 13 106 C1 is an anti-trap device with a hollow profile for a power operated Locking device has become known in which one as Hollow profile shaped terminal strip along a frame, for example, a sunroof opening is arranged.
  • the Hollow profile has two electrically spaced apart conductive areas whose contact is a switching operation triggers to actuate the motor of the locking device.
  • the production of such a safety edge is right complex, and the application is such a system susceptible to false triggers, particularly caused by the permanent deformation or wear of the electrically conductive areas is caused.
  • the inventive device with the features of Claim 1 has the advantage that a simple and robust Pinch protection is created, the little additional Has components and is simply in current Sealing profiles can be integrated.
  • the mechanical principle that the rope in the seal in the presence of a Obstacle is very reliable and deflected susceptible to interference.
  • the force acting on the rope can be simple and varied ways to be measured and posed directly represents a quantitative measure for predeterminable spring rates, which are observed by the anti-trap device should. Since there are no electrical ones inside the seal Lines or contacts are necessary System-related susceptibility to malfunction of electrical safety edges prevented and an extremely inexpensive and anti-pinch protection implemented.
  • the Measuring device has a sensor which the spatial displacement of one end of the rope that measures through the pinching event is caused. Is the rope in his Approximately stiff in the longitudinal direction, one has an effect Displacement of the rope perpendicular to the rope longitudinal direction in the seal - caused by an obstacle - directly in a displacement of the rope end along its longitudinal direction out.
  • the tension in the Rope can be detected by means of a sensor, the Change in tension is also a measure of the deflection of the Rope through an obstacle and therefore also for the Pinching force acting on the seal represents.
  • the anti-trap device uses the flexible design conventional seals to deflect the rope approximately perpendicular to its longitudinal direction at To enable a pinching event to occur. For example, a deflection of 5 mm is sufficient to this at the end of the rope using a sensor demonstrated. To a defined deflection of the rope To ensure an obstacle, it is advantageous to use the rope to be arranged in a cable guide in or on the seal, this being simply a channel within the Seal can be molded.
  • the channel can be very inexpensively as a cavity in the Create the inside of the seal. It offers especially the extrusion process, with which the Rope guidance in one operation with the seal without any additional effort is made.
  • the wall of the The rope guide is also part of the Sealing profile and can with respect to the required Movability of the rope and the necessary stiffness requirements be optimized.
  • the rope guide can deflect the rope reliably detected an obstacle at the end of the rope become.
  • a lubricant for example talc.
  • the rope guide is on the side facing the part stiffened, it prevents the rope from being where there is no obstacle, is moved sideways. This is particularly necessary in the areas of sealing which the frame and the seal are not straight runs, but is rounded due to the shape of the part or kinks.
  • one end of the rope is on the frame, for example fixed, is only to determine the deflection of the rope a measuring device at the other end of the rope is necessary.
  • a spring means is arranged on the rope, to keep the rope taut. Through this bias it is guaranteed that the rope will become trapped after a trap moved back to its starting position and also Long-term expansion due to temperature changes or Signs of aging can be compensated.
  • the rope is particularly cheap as a core made of flexible Wire made of a friction-reducing sleeve Plastic, especially made of Teflon, is surrounded. Thereby one achieves a high rigidity in the longitudinal direction with a great flexibility for lateral deflections.
  • the inventive method with the features of Claim 13 has the advantage that by measuring the temporal change in the measured variable, from that to the rope acting force depends, slow changes in the measured variable due to external influences such as temperature, aging or Sun exposure can be eliminated. With that short-term changes in the measurand for the Pinch protection function evaluated with a previously determined threshold value of the change in the measured quantity over time be compared and if the value falls below or falls below the Threshold the part is stopped or reversed.
  • the actual value of the at least one measured variable measured continuously and with a stored Setpoint of the measured variable of the unloaded seal at compared to the open part, can at a certain Deviation from the target value also on the presence of a Trapping can be closed.
  • Figure 1 is a side window of a motor vehicle shown, as between a window pane movable part 10 and a window opening 12th enclosing frame 14 substantially parallel to this a flexibly shaped seal 28 is arranged.
  • the Disk 10 can be pulled by means of a motor 20 22 moves up and down along the direction of movement 24 become.
  • 28 as a pinch protection device a rope 16 arranged at one end 38 on the frame is attached and at the other end 40 with a Measuring device 30 is connected.
  • the measuring device 30 has a sensor 34 for determining the spatial Displacement of the rope end 40 on the one Control unit 32 of the motor drive 20 is connected.
  • An ohmic strain gauge sensor serves as a measuring sensor, due to a local expansion of a Semiconductor element generates an electrical signal.
  • the Absolute value of the measured variable constantly with a given one Setpoint compared, which was previously in an unloaded state the seal 28 is stored.
  • Setpoint at predefinable intervals, for example at at least partially opened pane 10, always new stored. If the measured quantity exceeds a predefinable one Difference to the setpoint, this is recognized as a trapping event and the motor 20 stopped or reversed.
  • FIG. 2 shows a further inventive Embodiment in which the rope 16 in a Cable guide 18 is arranged as a channel in the seal 28 is formed.
  • the rope 16 consists of a flexible Core 56 made of wire and a sleeve 58 made of Teflon, which the Friction between the rope 16 and the wall of the rope guide 18 minimized from rubber.
  • a Lubricants such as talc, can be used to control the To reduce friction between the rope 16 and the rubber.
  • the rope 16 has at one end 38 a spiral spring executed spring means 42 with which the rope 16 on Frame 14 is attached.
  • a sensor 34 for determining the tension in the rope 16 arranged, also on the frame 14 or a fixed Part of the vehicle door is fixed.
  • the sensor 34 has For example, a piezoelectric element 44 that the tensile stress 46 occurring in the rope 16 into an electrical one Signal converts and feeds a measuring device 30.
  • the The signal is evaluated in accordance with exemplary embodiment 1 either via the change in the measured variable over time or the Comparison with a preset threshold.
  • the Spring element 42 serves to maintain a predeterminable preload force, through the long-term influences of Change in length of the rope 16 can be compensated. To a Deflection of the rope 16 towards a pinching area restrict, the cable guide 28 in the kink area of the Seal 28 on the side facing the disc 10 Stiffening 50 on.
  • Figure 3 shows a section through the frame 14 of the Side window 10 with one inserted into the frame 14 Seal 28.
  • the seal 28 has two flexible sealing lips 48 on.
  • Within the seal 28 are two as a rope guide 18 Channels arranged, for example, by extrusion are integrally formed with the seal 28. Thereby forms the material of the sealing lip 48, usually rubber, at the same time the wall of the rope guide 18. If the Disc 10 when undisturbed, i.e. if no If there is a jam, closed, the changes spatial position of the rope guides 18 and 16 ropes not. The disc 10 only presses against the sealing lips 48, but not against the rope guides 18.
  • the maximum possible displacement of the ropes 16 along the Closing direction 24 of the disc 10 is due to the flexible Execution of the seal 28 given. This contributes to the one hand the elastic material, usually rubber, the seal 28, but also the specific shape of the side Sealing sections 52, as well as the distance 54 between the rope 16 and frame 14 and is, for example, 5 mm.
  • sensors 34 can also be used capacitive or inductive sensors are used which a displacement of the rope end 40 or a change in Detect tension 46 in rope 16.
  • the sensors 34 are preferably arranged at a location that is only exposed to minor vibrations, so at the motor vehicle door, for example, in the vicinity thereof Hinges.
  • the signal evaluation can be in the sensor 34 or can also be integrated into the control unit 32.
