Detailed Description

First, a fixing anchor 3 for a side curtain drawstring according to an embodiment of the present invention will be described with reference to fig. 1 and 2. The anchor 3 can be produced integrally from sheet metal, for example by stamping and/or machining.

The anchor 3 has a body 30, the body 30 being in the form of a sheet. The body 30 has attachment holes 31 for attaching side curtain pull straps and mounting holes 32 for receiving fastening elements. The connection hole 31 is formed as a rectangular hole, and the mounting hole 32 is formed as a circular hole. The connection hole 31 is penetrated through the mounting hole 32. The opening size of the through portion between the connection hole 31 and the mounting hole 32 is about 2/3 of the diameter of the mounting hole 32. The end region 35 of the body 30 adjacent to the connection opening 31 is bent out of the body 30. As shown in fig. 2, the end region 35 is bent at an angle of about 30 ° with respect to the body 30. The anchor 3 has a hook 33 bent out of the body 30. As shown in fig. 2, the hook 33 forms an angle of about 90 ° with the body 30. The hook 33 transitions into the body 30 via a neck 34. The hook 33 protrudes on both sides with respect to the neck 34.

Next, a connection system according to an embodiment of the present invention, which includes the anchor 3 shown in fig. 1 and 2, will be described with reference to fig. 3 and 4. The connecting system is particularly suitable for application scenes in which the side air curtain pull belt only needs to bear small pulling force during the unfolding process of the side air curtain. Fig. 3 and 4 show a partially depicted body part 1. The body component may be an integral part of the body or may be an accessory attached to the body. The body part 1 may be a sheet metal part, for example. For example, the body part 1 can be located in the region of a pillar, for example in the region of an a-pillar.

The body part 1 has a hook receiving hole 10. Hook receiving hole 10 may be a waist-shaped hole, wherein the major diameter of the waist-shaped hole has a dimension greater than the width of hook 33 of anchor 3, and the minor diameter of the waist-shaped hole has a dimension less than the width of hook 33 and greater than the width of neck 34.

The hook 33 is hooked in the hook receiving hole 10 of the vehicle body member 1. The hook 33 is held in the hook receiving hole 10 by the fixing member 4 fitted into the hook receiving hole 10. The fixing element 4 is here a tree rivet as shown in fig. 5. The tree rivet presses the hook in the hook receiving hole 10 so that the hook is held in the hook receiving hole 10 against rotation. The tree rivet has a plurality of barbs on its shank portion, which are elastic, in succession to each other in the axial direction of the shank portion.

Here, the mounting hole 32 is unused. The side curtain pull tape 2, which is formed as a webbing, is passed through the connecting hole 31 of the anchor 3 with one end section thereof and folded back and sewn, and thus the side curtain pull tape 2 is fixed to the hole edge of the connecting hole 31. As a square hole, for example, the side length of the connecting hole 31 is about 4/5 of the width of the webbing. Alternatively, the connection hole 31 may be formed as a slit or a semicircular hole.

The connection system according to fig. 3 and 4 can be assembled in such a way that: the long sides of the hook 33 of the fixing anchor 3 are first oriented parallel to the long diameter of the hook receiving hole 10, and then the hook 33 is inserted into the hook receiving hole 10; the anchor is then rotated 90 deg. so that the hook 33 hooks the hook receiving hole 10 from the back of the hook receiving hole 10, as shown in fig. 4; a tree rivet as the fixing element 4 is then inserted into the hook receiving hole 10 and pressed. The tree rivet squeezes the hanger 33 which limits the possibility of rotation of the hanger 33 in the hanger receiving hole 10. In this manner, the tie-down anchor 3 is anchored in the hook receiving hole 10. The anchor 3 provides the side curtain draw tape 2 with the required tension when the side curtain is activated, such as in the event of a vehicle collision, and does not fall out of the hook receiving hole 10.

In the following, a connection system according to another embodiment of the invention is described with reference to fig. 6 and 7, which comprises a tie-down anchor 3 as shown in fig. 1 and 2. The connecting system is particularly suitable for application scenes that the side air curtain pull belt needs to bear large pulling force in the unfolding process of the side air curtain. Fig. 6 and 7 show a partially depicted vehicle body part 1. The body component may be an integral part of the body or may be an accessory attached to the body. The body part 1 may be a sheet metal part, for example. For example, the body part 1 can be located in the region of a pillar, for example in the region of an a-pillar.

The body part 1 has a hook receiving hole 10. The hook receiving aperture 10 includes a first region having a first width that is greater than the width of the hook 33 and a second region having a second width that is less than the width of the hook 33 and greater than the width of the neck 34. It is understood that the shape of the hook receiving apertures is merely exemplary. It is also contemplated that the hook receiving apertures 10 in the two embodiments described above may be provided interchangeably. The hook 33 is hooked in the hook receiving hole 10 of the vehicle body member 1. The hook receiving hole 10 is unoccupied except for receiving the hook 33, in other words, the fixing member 4 is not disposed in the hook receiving hole 10. It goes without saying that it is also possible to provide fixing elements 4 or other elements in the hook receiving openings 10.

The vehicle body component has fastening element receiving holes 9 for receiving the fastening elements 5, and bolts as the fastening elements 5 are passed through the mounting holes 32 of the fixing anchors 3 and the fastening element receiving holes 9 of the vehicle body component 1 and fastened to the vehicle body component 1 by nuts 6, thereby firmly fixing the fixing anchors 3 to the vehicle body component 1. The nut 6 can be fixed to the body part 1 in advance, for example by gluing, welding or clinching to the body part 1. Alternatively, it is also possible for the nut 6 to be screwed onto the bolt as a separate component.

The side curtain pull tape 2, which is formed as a webbing, is passed through the connecting hole 31 of the anchor 3 with one end section thereof and folded back and sewn, and thus the side curtain pull tape 2 is fixed to the hole edge of the connecting hole 31.

The connection system according to fig. 6 and 7 can be assembled in such a way that: first inserting the hook 33 of the fixing anchor 3 into a first region of the hook receiving hole 10 having a larger width, and then moving the hook 33 into a second region of the hook receiving hole 10 having a smaller width, so that the fixing anchor 3 hooks the hook receiving hole 10 through the hook 33 thereof; next, bolts as the fastening elements 5 are inserted into the mounting holes 32 of the anchor anchors and the fastening element receiving holes 9 of the vehicle body member 1, and screwed into the nuts 6. Particularly advantageously, clinch nuts crimped onto the body part 1 or nuts welded to the body part 1 can be used, which makes the installation of the bolts easier. The non-circular hook receiving hole 10 may provide a degree of anti-rotation of the hook, which facilitates subsequent bolting, which may be accomplished electrically, for example, by a torque gun.

When the side curtain is activated, for example, in the event of a vehicle collision, the anchor 3 provides the required tension to the side curtain pull tape 2 and does not fall off the body part 1 even at high tensions.

Compared with the prior art, according to the utility model discloses a fixing anchor can match in multiple assembly demand, can select the assembly methods as required in a flexible way, especially can select an assembly method as shown in fig. 3 and 4 or an assembly method as shown in fig. 6 and 7.
