Abstract: The invention relates to a pipette with a body for receiving a displacement device, the displacement device comprising a displacement chamber and a movable boundary element for bounding a pipetting stroke of the pipette. The pipette furthermore has an operating element for setting the pipetting volume of the pipette by movement of the boundary element in the body and for performing a pipetting operation, the operating element being in operative connection with a piston movable in the displacement chamber of the displacement device. The pipette furthermore comprises a counter for displaying the set pipetting volume and a locking mechanism for locking and/or unlocking volume setting by the operating element. It is provided that, on actuation of the operating element, the operating element is configured to perform a pipetting operation, to transfer the locking mechanism into a locked position and to lock adjustment of the pipetting volume.

Abstract: A self-locking belt retractor for a seat belt device of a motor vehicle with a belt shaft body and a profile head, and a blocking device with a blocking catch mounted on the profile head. When activated, the blocking device engages in a blocked position with a vehicle-affixed interlock for the purpose of blocking the belt shaft in the belt extension direction. A force-limiting device is disposed in the force transmission path from the belt shaft body to the blocking catch. The profile head is made as two parts, with a carrier component and an insert component which are affixed together. The insert component exhibits a higher resistance to deformation than the carrier component and, when the belt shaft is blocked, forms part of the force transmission path between the blocking catch and the force-limiting device.

Abstract: A seat belt (2) for motor vehicles, has a restraining element (4) for a seat belt tongue (3). The restraining element protrudes from the seat belt (2), from only on one side thereof and the seat belt (2) may be configured as a multi-layer seat belt (2) forming a hollow space (5) between the seat belt layers (21, 22).
