Abstract: A headrest for a vehicle. A supporting body is mounted on a backrest of the seat, and a head support is adjustable and arrestable relative to the supporting body along a horizontal axis. The headrest includes a first arresting mechanism and second arresting mechanism that is disposed parallel to the horizontal axis and is provided with arresting stages. For an arresting of the head support on the supporting body, the first arresting mechanism is configured to engage into the second arresting mechanism under the effect of a biasing force. The first arresting mechanism is further configured such that it can travel over an angle of rotation about the horizontal axis counter to the biasing force.

Abstract: A support pin component for attachment to a reclining part of a vehicle seat and for insertion into a support receiver of a support frame, and a vehicle seat having a support pin component. The support pin component comprises an attachment region configured for attachment to a reclining part of a vehicle seat, and a pin, preferably having an internal thread, configured for pivotable insertion into a support receiver of a seat frame. The support pin component is a shaped part of sheet steel.

Abstract: A slide fastener element, cushion arrangement, vehicle seat or interior covering part. The slide fastener element includes a flexible, foamable lattice that is provided with a plurality of holes, and a plurality of slide fastener teeth secured directly to the lattice.

Abstract: A method of controlling conveyance of the debris, extracted by working machines in underground mining operations, via conveyors and bunker units. The lowest available conveying capacity of the conveyors and buffer capacity of the bunker units are determined based on continuously detected actual data and are compared in a computer-aided control unit to at least one of current actual extraction output, anticipated target extraction output, and scheduled output extrapolated from past actual data. Upon detection of deviations, the control unit automatically effects a balancing of capacities between the conveyors and bunker units connected at an output side of each individual different working machine, taking into consideration their maximum conveying capacity and buffer capacity respectively, and/or controls the extraction output of the working machines taking into consideration respectively available conveying capacity of downstream conveyors and buffer capacity of the bunker units.
