The present disclosure relates to a drive screw for connecting a carrier formed of foamed material to a part to be affixed to the carrier. In one implementation, the drive screw includes a threaded pin with a first end having shaped elements configured to connect to a tool that transfers torque and a second end configured to penetrate into the carrier. In addition, the first end of the threaded pin may be surrounded by and connected to an interlock component, and the part to be affixed may have an interlock receiving space corresponding to the interlock component.

Drive screw

The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to affix the support component to the additional component. The support component comprises a tube made of plastic to accommodate the screw in a friction and positive fit, wherein the tube comprises a thermoplastic foam. The screw comprises a blunt-edged screw thread. The foam is compacted as the screw is driven into the tube. The present disclosure further relates to a corresponding screw and to a method of connecting a support component to an additional component using the screw.

Screw connection for a component made of thermoplastic material

The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to fasten the support component to the additional component. The support component has a tube made of thermoplastic foam to accommodate the screw in a friction and positive fit. The screw has a blunt-edged thread, enabling the screw to compress the foam in the tube as it is driven in. The ratio of the inner diameter of the tube to the diameter of the screw depends on the degree of foaming of the tube and decreases as the degree of foaming increases. In comparison to conventional screws, the threads of the screw of the present disclosure penetrate less deeply into the foam or they displace it, preventing damage to the tube while enabling a tight fit.

Screw and screw connection for components made of foamed plastic

The present disclosure shows an anti-rotation device for a lock system in a motor vehicle, comprising a base cover unit having an opening for passage of a lock system; a cover unit; a rotor rotatably attached to a back side of the base cover unit by a latch mechanism, in which the rotor has a radial rib structure; a hollow receiving body accommodating the rotor and having a recess; and an interlock system on a circumferential line of the recess of the receiving body. On rotation of the rotor in the receiving body the position of the rotor in the receiving body is ascertained by the contact of the interlock system with the rib structure.
