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 on a vehicle for preventing trapping of an object between two parts of the vehicle, comprising:

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

a detection device for detecting a relative movement between the actuating means and the body part;

a rotary axle mounted on the body part, and wherein the actuating means is pivotally mounted to the rotary axle; and

a fastening strip which is fixedly attached to the body part of the vehicle and to which the actuating means is articulatedly connected by the rotary axle, the fastening strip further comprising a guide means, which is spaced apart from the rotary axle, for mounting and pivoting guidance of the actuating means;

wherein the guide means is embodied as a guide bolt which is mounted on the fastening strip and which engages into a slot which is provided in the actuating means and which is aligned in the direction of the pivoting movement.

2. The anti-trap device of claim 1,

wherein the rotary axle is assigned to that region of the body part on which lower trapping forces act relative to regions of the body part on which higher trapping forces act, and in that the guide means is only assigned to that region of the body part on which the higher trapping forces act.

3. The anti-trap device of claim 1 wherein the actuating means can be preloaded with respect to the fastening strip by means of a spring device.

4. The anti-trap device of claim 1, wherein the actuating means is embodied as a leader strip which is pivotable relative to the body part about the rotary axle.

5. The anti-trap device of claim 1 being disposed in the region of each longitudinal side of a rear flap of the vehicle.

6. The anti-trap device of claim 1, wherein the detection device is at least one of:

an electric switch,

a proximity switch,

a mechanical switch,

an electromechanical switch,

a microswitch,

an inductive switch, and

a sensor.

7. The anti-trap device of claim 1 wherein the detection device is at least one of:

a switch of which the guide means forms a constituent part, a microswitch having a mating contact surface formed by the guide means, and

a Hall sensor partially formed by the guide means.

8. The anti-trap device of claim 1, wherein the detection device is embodied as a tactile sensor strip at the actuating means.

9. The anti-trap device of claim 1, wherein the detection device is embodied as a sensor which can be attached to a mating contact section, which is assigned to the body part, of the vehicle body.

10. The anti-trap device of claim 1, wherein the vehicle has an automatically actuable body part with a drive mechanism, and wherein when a relative movement between the actuating means and the body part is detected, the drive mechanism of the body part can be deactivated.

11. The anti-trap device of claim 1, wherein the actuating means has a main body made of plastic material.

12. The anti-trap device of claim 1, wherein the vehicle has a manually actuable body part and is configured to emit a warning signal, and wherein when a relative movement between the actuating means and the body part is detected, the vehicle emits the warning signal.

13. An anti-trap device on a vehicle for preventing trapping of an object between two parts on the vehicle, comprising:

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

a detection device for detecting a relative movement between the actuating means and the body part; and

a fastening strip which can be fixedly attached to the body part of the vehicle, the fastening strip having a rotary axle defining a direction of pivoting movement, the actuating means being articulatedly connected to the rotary axle to pivot about the rotary axle, and

the fastening strip having a guide means, which is spaced apart from the rotary axle, for the mounting and pivoting guidance of the actuating means, wherein the guide means comprises a guide bolt mounted on the fastening strip and which engages into the slot, the slot being aligned in the direction of the pivoting movement.
