While the partial travel Si is covered, the cam 60 thus prevents the blocking lever 35 from becoming effective, and thus permits a relative pivoting of the coupling lever 23 relative to the closing part 11 in the event of an obstacle entering the path of movement of the vehicle door.
- FIG. 26 shows the operating state of the device during a normal closing operation without the result of a pinching protection situation.
- the drive pulley 28 rotates clockwise and takes over the coupling pin 26, the drive lever 52 counterclockwise around the pivot axis 12 with. This transmits the force on the pivot axis 56 on the coupling pin 57 of the pawl 55th
- the connecting line between the pivot axis 56 and the pivot axis 12 is denoted by R.
- the direct connection line between the pivot axis 56 of the pawl 55 and the coupling pin 57 of the pawl 55 is designated K.
- the connecting line between the coupling pin 57 and the pivot axis 24 of the coupling lever 23 is designated T.
- the drive lever 52 exerts on the pawl 55 via the pivot axis 56 a force which is tangent to the connecting line R.
- the connection line K is in the normal operating state of the device 10 according to FIG. 26 essentially perpendicular to the connecting line T. This causes the force-resulting force exerted by the coupling pin 57 on the coupling lever 23 substantially along the arrow N, ie in the Extension of the line K runs. The force directions remain substantially retained during a closing operation and rotate in total about the pivot axis 12.
- the angle ⁇ between the connecting lines K and T always remains about 90 °.
- Fig. 20 shows a later operating state at a
- Fig. 20 shows the situation in which the coupling pin 57 a Shoulder 77 of the coupling lever 23 has already happened.
- the drive 27, not shown in FIG. 20, can no longer exert any force on the coupling lever 23 or the closing part 11 and is completely decoupled from the closing part 11.
- the device 10 After completion of the anti-trap situation, the device 10 reverses automatically.
- the drive 27 returns to its initial position and the spring 30 pivots the coupling lever back to its original position.
- FIG. 16 shows, in a further, supplemented exemplary embodiment, a circuit arrangement 62, which has a switch 63 indicated schematically.
- the switch assembly 62 is associated with a pivotable about a body side pivot axis 64 pivotable switch lever 65 having a control surface 66.
- the switch lever 65 is pivotable between the normal position NO shown in dashed lines and the operating position B shown in solid lines.
- the switch lever 65 located in the normal position NO has a control surface 66, which corresponds to a circular arc around the pivot axis 12.
- the control cam 58 is displaced out of its circular path and actuates the switch lever 65 in such a way that it rotates clockwise from its normal position NO Swivel axis 64 pivoted in its operating position B.
- the switch 63 is actuated.
- Actuation of the switch may generate a signal that is passed to a controller.
- the controller can switch off or interrupt the drive 27 and thus prevent an obstacle which is clamped in the path of movement of the movable vehicle part from being subjected to further forces.
- FIG. 17 the composite device 10 with the two assemblies of FIG. 6 and according to FIG. 10 is apparent from a very flat perspective view, this illustration illustrates the two different, spaced function levels.
- the upper functional plane with respect to FIG. 17 is essentially formed by the closing part 11 and the coupling lever 23, and the lower functional plane with respect to FIG. 17 is essentially formed by the drive lever 52 and the pawl 55.
- FIG. 17 additionally shows an emergency locking lever or emergency decoupling lever 67, which will be explained below with reference to FIGS. 17 to 19 with respect to its function:
- the emergency locking lever 67 serves on the one hand an emergency decoupling and on the other hand an emergency lock.
- the emergency locking lever 67 is pivotable about the body-mounted pivot axis 68, as best shown in FIG. It has a first actuating end, which ends at an actuating pin 75, on which a user can manually attack if necessary. On the actuating pin 75 but also the end of a Bowden cable or other mechanical actuator can be connected.
- the second arm of the emergency locking lever 67 terminates at a locking nose or claw 72, which can cooperate with a latching recess 73 on the closing part 11.
- a spring element 69 is fastened to the vehicle body at an attachment point 70 and connected at its other end in the region 76 to the emergency locking lever 67.
- the spring element 69 allows two stable positions, which are indicated in Fig. 18 with Li and L 2 .
- the emergency locking lever thus represents a Kippspanntechnik.
- the spring 69 biases the emergency locking lever 67 counterclockwise about its pivot axis 68 against a stop, not shown.
- the spring element 69 biases the emergency locking lever 67 in a clockwise direction in such a way that the latching claw 72 contacts the closing element-side control surface 74.
- the emergency lock lever 67 is normally in its position L 2 as shown in FIG. 18. By applying force to the actuating pin 75 and applying torque, the emergency lock lever 67 can pivot clockwise through an angle of about 40 ° clockwise.
- the narrow side 71 of the emergency locking lever 67 that is, in the viewing direction of Fig.
- emergency decoupling lever which may also be referred to as emergency decoupling lever
- a complete decoupling of the closing member 11 from the drive 27 takes place so that the closing member 11 is moved to the vehicle door in the fully extended position when pulling can.
- the closing part 11 has a control surface 74, which runs counterclockwise about the pivot axis 12, along the latching lug 72 during a closing operation of the door, that is corresponding to a pivoting of the closing part 11, until the latching lug 72 can engage in the latching recess 73.
- the incidence process is favored by the spring bias of the spring 69.
- the emergency locking lever 67 thus allows a manual, complete decoupling of the drive from the closing part and even in case of failure of any electrical drives manual emergency decoupling and subsequently manual emergency locking of the vehicle door.
- a damping device 88 which, as shown in FIG. 12, consists of a piston 89 shown schematically and a cylinder 90 mounted on the body side.
- the piston 89 has at its the cylinder-facing free end on a plate-like widening.
- damper 88 may be a fluid shock absorber as well known for a variety of automotive applications.
- the damper 88 may allow slow, slowed down or delayed movement of the piston 89 relative to the cylinder 90, but counteracts a very rapid impulse-like movement of the piston 89.
- the device according to the invention can be used equally for the motorized opening as well as for the motorized closing of a vehicle door. equally Each motor-driven displacement of a vehicle part can be equipped with the anti-trap function according to the invention.
- FIG. 21 shows a perspective view of the closing part 11, on whose second arm 14 a projecting projection with a lower control flange 78 and an upper control flange 79 is arranged.
- the lower control flange cooperates with a lower sensing finger 86b (FIG. 21) of a lower switch 80
- the upper control flange 79 cooperates with an upper sensing finger 86a of an upper switch 81.
- the two sensing fingers 86a, 86b which are shown only schematically, are formed for example by a leaf spring-like manner to the pivot axis 12 toward slightly biased sheet.
- FIG. 22 shows a position of the closing element 11, in which the striker is extended, that is, in which the striker is tied before the start of a closing operation in a pre-locking position of the example, the vehicle door-side catch.
- FIG. 23 shows a position of the closing part 11 during the closing process, specifically during the first part of the path Si according to FIG. 7, that is to say during that part of the closing movement during which an anti-pinch protection has to be ensured.
- FIG. 24 shows the position in which the partial section Si according to FIG.
- FIG. 7 has been completely covered.
- FIG. 25 shows the completely closed position after the total distance s 2 has been covered .
- the sensing finger 86a of the upper switch 81 is due to the bias toward the pivot axis 12 in
- Switch 80 associated sensing finger 86b runs under bias into the void, as at the corresponding lower control flange 78 no corresponding
- Control surface is arranged.
- the upper sensing finger 86a comes into contact with the control surface 83, which is shown in FIG. At this time, therefore, the upper switch 81 is turned on again.
- both switches 80, 81 are switched on. If, starting from FIG. 24, the closing operation continues, the upper sensing finger 86a enters the second recess 85 of the upper control flange 79, which is illustrated in FIG. In this state, ie during the closing operation over the last section, after the first section si has passed through, the upper switch 81 is thus in an off state and the lower switch 80 in an on state.
- each of the four different positions of the striker causes a different switching state of the two switches 80, 81.
