Abstract: A safety belt retractor, especially in vehicles, is provided that includes a belt shaft as a carrier for a belt that is wound thereon and a vehicle sensitive and/or belt sensitive controllable block device for the belt shaft. The block device includes a force limiting device, effective in the event of a block event, the force limiting device having a viscous medium-filled housing with at least one fixedly positioned contour and a counter-contour that is rotatably displaceable in response to a block event, so that the relative movement between the contour and the counter-contour forces the viscous medium between the surfaces arranged for this purpose. The level of the force limitation applied by the force limitation device is adjustably settable as a function of the parameters associated with the buckled-in passengers via a variation of the inner pressure in the viscous medium-filled housing.

Abstract: A motor vehicle includes a body structure that has a lateral structure, a vehicle seat that is mounted on the body structure, and a side impact protection device for a passenger in the vehicle. The side impact protection device includes a head airbag with a first inflation device that can deploy upward in the region of the breastwork of the lateral structure, and a side airbag with a second inflation device that can deploy laterally out of the seat. In order for the side impact protection device to be used for different body structures, the side airbag is designed as a thorax airbag, which, in its ready state, is positioned, together with the second inflation device, inside the seat back of the vehicle seat, and can deploy essentially toward the front out of the side wall of the seat back. When the thorax airbag is in its deployed state, its upper edge comes to rest next to the breastwork of the lateral structure.

In a moved-in condition, the bag is folded together in a packet and, in an inflated condition, the bag extends along an interior side of a side window in order to protect a head region of an adjacent sitting occupant against an impact. To improve functioning of the safety device and reduce a space requirement, the packet is fully immersed in a door body of the door, and the protective bag unfolds during inflation from the door body, in a direction of a roof, essentially along the door window.

The unit is adapted to become of increased length in response to a signal from a sensor and may comprise a bellows-sleeve and a gas generator. The unit has a catch arrangement adapted to engage part of the bonnet structure so that part of the bonnet structure is engaged and retained when the length of the unit is increased.

Abstract: The present invention relates to a method and a device for making the combustion of a pyrotechnic compostion independent of the ambient temperature when combusting a pyrotechnic composition in a preinflator or combustion chamber (2) incorporating outlets but being otherwise enclosed. As claimed in the present invention this is enabled by controlling the burning pressure of the pyrotechnic composition so that it does not exceed a predetermined value. The characteristic feature of the present invention is that the preinflator (2), in which combustion of the pyrotechnic composition takes place, incorporates a plurality of gas discharge perforations (6–9) or outlets, each of which is initially sealed by a bursting disc or foil seal (10) that is designed to rupture when the said burning pressure in the combustion chamber (2) is exceeded.

Abstract: An inflatable air-bag (1) is disclosed which defines an inflatable chamber (3). The air-bag comprises an inner elastic membrane (5) provided in the peripheral wall of the air-bag, there being a vent-hole (7) formed through the elastic membrane (5). An outer membrane (8) is provided on the outside of the air-bag which extends across at atleast part of the inner membrane (5) and the vent-hole (7). The outer membrane defines a pucker (10) over the inner membrane and the vent-hole (7). The pucker (10) is open so as to define an outlet flow path from the vent-hole (7) when the inner membrane (5) is spaced from the pucker (10). The inner membrane (5) is configured to stretch and seal against the pucker (10) around the vent-hole (7) when tile internal pressure within the inflatable chamber (3) exceeds a predetermined value.
