Abstract: A device for preventing or extinguishing a fire in an electrochemical energy storage system comprising storage cells arranged in a storage housing, in particular lithium-ion cells, wherein a composition of expandable volume, containing a chemical compound for preventing or extinguishing a fire, is disposed with limited volume in one or a plurality of hollow spaces in or on the storage housing, and expansion of the volume of the composition can be activated by sensors.

Abstract: A device for preventing or extinguishing a fire in an electrochemical energy storage system comprising storage cells arranged in a storage housing, wherein the energy storage system is connected to a discharge unit for discharging energy from the energy storage system, the discharge unit comprising: at least one anchor, and a drive assembly for driving the at least one anchor to the ground, the anchor being electrically connected to the energy storage system, such when the anchor is driven to the ground, the energy storage system is grounded.

Abstract: An airbag arrangement for closeable or openable roof opening 2 of a motor vehicle has a gas cushion arrangement which is to be anchored to the vehicle roof 1 and which is suitable in the inflated state for covering the surface of the roof opening 2, wherein the gas cushion arrangement has two inflatable gas cushions 3, 4 which are suitable in the non-inflated state for being arranged along lateral inside edges 5, 6 of the roof opening 2, that extend in the longitudinal direction of the vehicle.

Abstract: Vehicle roof with at least one cover that, alternatively, closes or at least partially opens an opening in a fixed roof surface of the vehicle, carries a solar power source for supplying power to at least one power consuming device that is separately located from the cover, and with a contact device for producing an electrical connection between the solar power source and the consuming device. The contact device is made as a switch arrangement that incorporates the cover so that the power consuming device is connected to the solar power source in one or more predetermined cover positions and is disconnected from the solar power source in all other cover positions.

Abstract: Vehicle roof having a cover which, in a closed position, covers a roof opening in a fixed roof surface, and which can be extended above a fixed roof surface by pivotal movement about a pivotal axis which extends between its lateral edges. Below the cover, a cover liner is provided which, during upward extension of the cover, is bent about a center axis which is parallel to the pivotal axis of the cover. The liner, in a transversely extending center area, is provided with at least one cutout that extends transversely across a main portion of the liner and which reaches downwardly from the upper side of the liner, through a portion of the thickness of the liner sufficient to create a flexible hinge-like portion, thus permitting the liner to bend when the cover is extended. When the liner is in its unbent condition, the cutout has a cross-sectional shape that widens upwardly.

Abstract: Device for guiding of air flow on vehicles, especially rear spoilers, with an air deflector which, in relation to the vehicle body, can be moved between a retracted position and an extended position in which the air deflector, as a whole, is away from the vehicle body and, in relation to its orientation in retracted position, is inclined. The air deflector is supported by an arcuate adjuster that is rigidly connected to it and which is slidably guided in a correspondingly arcuate guide channel of a guide block that is fixed with reference to the vehicle body.
