Abstract: A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

Abstract: The disclosure concerns a seal, in particular a rod seal for sealing an axially movable rod in a guide cylinder, in particular a piston seal for a pneumatically, electrically or hydraulically driven coating agent pump for pumping coating agent, having an annular sealing element for sealingly resting on a circumferential surface of an axially movable rod, and having at least one elastic annular pretensioning element, the annular pretensioning element surrounding the annular sealing element radially on the outside and pretensioning it radially to the inside. The disclosure provides an annular seal base body which externally surrounds and holds the sealing element and the pretensioning element. In addition, the disclosure also comprises an inverted variant in which the seal is arranged in an annular groove in a lateral surface of a piston and lies sealingly against the cylinder running surface.

Abstract: A seating arrangement for a motor vehicle having at least one front vehicle seat and at least one rear vehicle seat in which the front vehicle seat has a backrest provided at a backrest frame as a unit which can be attached at least indirectly on the backside of the seat back and receives the headrest. A display screen or monitor can be mounted in that frame in a field or space specifically provided for that unit.

Abstract: Electrical knife having an elongate cutting device and an electric motor, the cutting device having a first blade and a second blade which is arranged parallel to said first blade, which blades are suitable for the electric motor to importing them a counter-rotating oscillating movement in the direction of their longitudinal axis, the cutting device also being equipped with a fixed guide tongue which at least partly extends along the blades and which is suitable for guiding the blades in the longitudinal direction.
