Abstract

The invention relates to an anti-jamming device in the field of motor vehicles, which is used for preventing an object from getting caught. Said anti-jamming device comprises an actuating means (1) which can be coupled to a body part (3) of a vehicle and can be moved relative to said body part (3) by resting the same against the object, and an apparatus for detecting a relative movement between the actuating means (1) and the body part (3).

Claims

1. An anti-trap device in the field of motor vehicles for preventing trapping of an object, having:

an actuating means (1) which can be coupled to a body part (3) of a vehicle and, as a result of contact against the object, is movable relative to the body part (3); and

having

a detection device for detecting a relative movement between the actuating means (1) and the body part (3).

2. The anti-trap device as claimed in claim 1, characterized

in that the anti-trap device has a fastening strip (2) which can be fixedly attached to the body part (3) of the vehicle and to which the actuating means (1) is articulatedly connected so as to be pivotable about a rotary axle (20).

3. The anti-trap device as claimed in claim 2, characterized

in that the fastening strip (2) has the rotary axle (20) and a guide means (21), which is spaced apart from the rotary axle (20), for the mounting and pivoting guidance of the actuating means (1).

4. The anti-trap device as claimed in claim 3, characterized

in that the guide means (21) is embodied as a guide bolt (21) which can be mounted on the fastening strip (2) and which engages into a slot (11) which is provided in the actuating means (1) and which is aligned in the direction of the pivoting movement.

5. The anti-trap device as claimed in claim 3 or 4, characterized

in that the rotary axle (20) is assigned to that region (31) of the body part (3) on which relatively low trapping forces act, and in that the guide means (21) is assigned to that region (32) of the body part (3) on which relatively large trapping forces act.

6. The anti-trap device as claimed in at least one of claims 1 to 5,

characterized

in that the actuating means (1) can be preloaded with respect to the fastening strip (2) by means of a spring device (13).

7. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that the actuating means (1) is embodied as a leader strip (1) which is pivotable relative to the body part (3) about a rotary axle (20).

8. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that in each case one leader strip (1) is pivotably attached, for example by means of in each case one associated fastening strip (2), in the region of each longitudinal side (30) of a rear flap (3) of a vehicle.

9. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that the detection device is embodied as an electric switch, for example proximity switch, as a mechanical switch, as an electromechanical switch, for example a microswitch, as an inductive or as some other type of switch or sensor which can be suitably attached to the body part (2), to the fastening strip (2) and/or to the actuating means (1) corresponding to its respective use.

10. The anti-trap device as claimed in at least one of claims 3 to 9,

characterized

in that the detection device is embodied as a switch of which the guide means (21) forms a constituent part, for example the mating contact face of a microswitch or a constituent part of a Hall sensor.

11. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that the detection device is embodied as a tactile sensor strip which can be attached to the face, which comes into contact with the object, of the actuating means (1).

12. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that the detection device is embodied as a sensor which can be attached to a mating contact section (40), which is assigned to the body part (3), of the vehicle body (4).

13. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that, when a relative movement between the actuating means (1) and the body part (3) or the fastening strip (2) is detected, the drive mechanism of the body part (3) can be deactivated in the case of an automatically actuable body part (3), and a warning signal can be generated in the case of a manually actuable body part (3).

14. The anti-trap device as claimed in at least one of the preceding claims,

characterized

in that the actuating means (1) and/or the fastening strip (2) are produced from plastic.
