Abstract: A safety seat for land vehicles, aircraft or vessels, comprising a harness for suspension from fixed points of a vehicle and for supporting a vehicle occupant. Belt retractors are disposed at the fixed vehicle points, and fabric supporting belts extend from the harness to the retractors, which pretension the belts in a direction of retraction. A manually operable switching device allows the belt retractors to be switched into a free running state, a blocking state, or a positioning state. The free running state permits free withdrawal of the belts in a direction opposite to the pretension. The blocking state effects a complete blocking of the belts in both the withdrawal and the retraction directions. The positioning state effects blocking of the belts in only the withdrawal direction.

Abstract: The inventive device for fixing a seat belt winder is fixed to the part of a motor vehicle. The plate of the housing of the winder is provided with at lest one fixing hole for receiving a screw connection which maintains the vehicle part embodied therein. The housing of said seat belt winder is arranged in such a way that it is rotatable with respect to the fixing hole of the vehicle part, thereby enabling the winder to be automatically oriented in a direction of a force of a belt which moves at an angle with respect to the axis of the shaft. Said fixing device is characterised in that the housing (10) of the winder is rotationally maintained on the holder part (13, 19, 25) which can be firmly connected to the vehicle part (40).

Abstract: A process for treating a yarn with a gas- or steam-creating medium includes traveling the yarn between a pair of elongate yarn guide elements in a pressure chamber portion of a yarn treatment chamber that is substantially sealed off to the environment and is under an overpressure. The process further includes drawing the yarn through an additional yarn guide element. The cross section of the one pair of elongate yarn guide elements and the cross section of the additional yarn guide element correspond to the thickness (titer) of the yarn traveling through these yarn guide elements such that the yarn travels through these yarn guide elements in a substantially friction-free manner and the one pair of elongate yarn guide elements and the additional yarn guide element operate in cooperation with the yarn treatment chamber such that the yarn treatment chamber is substantially sealed off against loss of pressure.
