Abstract: An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction.  This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded.  The velocity of motion is controllable preferably around the resonant frequency of the driven structure by adjusting the frequency of the AC power which operates the electromagnetic drive motor of the welder.  A plate which carries one of the parts to be welded and which is driven is flexurally mounted for movement in an orbital plane or planes containing the interfaces without substantial tilting by an array of stiff members, such as rods, located around the drive motor, attached to the plate at one end and to a tubular structure at the opposite ends thereof.  The tubular structure is desirably attached to a massive support carried by the frame of the welder.

Abstract: A vehicle occupant restraint having an adjustable web tether utilizes a first section of webbing that is tautly positioned between the vehicle floor and an upper mounting location. A second section of webbing extends from a floor-mounted (or wall- or seat-mounted) emergency locking retractor (ELR) and through a turning point at the upper mounting location, after which the second webbing section transitions to a shoulder belt for the occupant. In order to provide a pivot point for the shoulder belt, an adjustable web tether is mounted to the first webbing section and captures the second webbing section in sliding engagement by means of a ring. The ring of the web tether therefore provides a pivot point for the shoulder strap.      The vertical position of the web tether upon the first webbing section is adjustable, so that the height of the shoulder strap pivot point, and therefore the trajectory of the shoulder strap across the occupant, is adjustable.
