Abstract:
A device for fastening side impact supports, and door or flap hinges (10) to the doors (12) or flaps or to the bodywork of motor vehicles, with a screw (141) which extends through an opening in the door (12), the flap or the bodywork sheet and through an opening in the side impact support or hinge (10), and is secured by a nut (16), in which a hollow absorber element (18) is arranged between the nut (16) and the sheet of the door (12), the flap or the bodywork or the side impact support or the hinge (10), which absorber element is penetrated by the screw (14') and has side walls (20) which run substantially parallel to the axis of rotation of the screw (14'), and two abutment surfaces (22, 26, 34) each running perpendicularly to the axis of rotation of the screw (14'), wherein the one abutment surface (26, 34) is supported on the sheet of the door (12), the flap or the bodywork or the side impact support or the hinge (10) while the other abutment surface (22) bears the nut (16). The invention also relates to similar devices in which an inner thread is provided on the absorber element instead of the nut.
Abstract:
The invention relates to a self-locking nut (10) having an internal thread (12) with a core hole which has one or a plurality of regions (14) having a reduced internal diameter.

A device for fastening side impact supports, and door or flap hinges (10) to the doors (12) or flaps or to the bodywork of motor vehicles, with a screw (14') which extends through an opening in the door (12), the flap or the bodywork sheet and through an opening in the side impact support or hinge (10), and is secured by a nut (16), in which a hollow absorber element (18) is arranged between the nut (16) and the sheet of the door (12), the flap or the bodywork or the side impact support or the hinge (10), which absorber element is penetrated by the screw (14') and has side walls (20) which run substantially parallel to the axis of rotation of the screw (14'), and two abutment surfaces (22, 26, 34) each running perpendicularly to the axis of rotation of the screw (14'), wherein the one abutment surface (26, 34) is supported on the sheet of the door (12), the flap or the bodywork or the side impact support or the hinge (10) while the other abutment surface (22) bears the nut (16).
Abstract:
A self-tapping screw (10) having a head (12) and an outer thread carrier (16) with an end (20) at which the outer thread (18) has an outer diameter decreasing towards the end (20), at least over a part (K) of the length thereof ending at the end (20), and the outer diameter of the outer thread (18) decreases according to the draft angle of holes in which the screw (10) is to be set.
Abstract:
The invention relates to a device for fastening plastic parts (10) to a motor vehicle body (12), having an internal thread (14) which is formed on the body (12) and having a screw (16) which has an external thread (18) and which is provided with an oversized head (20), which screw (16) is inserted into the internal thread (14), wherein a cylindrical sleeve (22) is placed between the screw head (20) and the body (12), the inner diameter of which cylindrical sleeve (22) is significantly larger than the outer diameter of the external thread (18) of the screw (16), and wherein a cylindrical sleeve (24) is attached coaxially, by means of its inner edge which faces toward the body (12), to the outer edge, which faces away from the body (12), of the sleeve (22), the inner diameter of which cylindrical sleeve (24) forms a fit with the outer diameter of the sleeve (22), and which cylindrical sleeve (24) ends, at its body-side end, in an outwardly extending disk (26), the outer diameter of which corresponds approximately to the outer diameter of the screw head (20), wherein an opening (28) for receiving the device is provided in the plastic part (10), the inner diameter of which opening (28) is larger than the outer diameter of the sleeve (24) but smaller than the outer diameter of the flat washer or of the oversized screw head (20) and of the disk (26) which is attached to the sleeve (24).
