A gas bag module () includes a gas bag (), the gas bag having a front wall () facing an occupant () in an inflated state of said gas bag () and being engaged by a first end () of a destructible retaining element (), the retaining element () at least partially preventing an unhindered motion of the front wall () when the gas bag () is inflated. The gas bag module further includes a gas generator () for filling the gas bag (), the gas generator () having a first discharge section () for a through flow of a first quantity of gas. The gas generator () has a separate, second discharge section (), which can have a second quantity of gas flow through it in a way that is selectively independent of a release of the first quantity of gas or has a time delay with respect to the release of the first quantity of gas, the second quantity of gas being hot gas, which flows to the retaining element () through the second discharge section () so as to cause a destruction of the retaining element ().

Gas bag module

A gas bag module includes a gas generator (), a gas bag () in flow connection with the gas generator, and a module covering. The module covering covers the gas bag and has a separate central part () after opening of the module covering. The gas bag module further has a holding device () for the central part.

A group of first latching elements () is provided on the gas bag module () or the steering wheel base body (), and at least one second latching element (), able to be brought into reversible locking engagement with the first latching elements (), is provided on the steering wheel base body () or the gas bag module (). When the assembly () has been put together, the first latching elements and the at least one second latching element () are arranged so as to be movable with respect to each other in an unlocking direction (R; R'). The first and second latching elements () are designed such that through a movement of the second latching element () relative to the first latching elements () in the unlocking direction (R; R&#x2032;) all latching connections () are released simultaneously in a non-destructive manner.

An assembly comprises a gas generator with a flange and a generator holder, on which the flange is fastened. The generator holder has a cylindrical peripheral wall, the peripheral wall at least partially surrounding the gas generator peripherally. At least one clamping extension is provided in the peripheral wall, which is formed by partial lateral deformation of the peripheral wall. The clamping extension is delimited by at least one slit in the peripheral wall. The slit runs substantially in peripheral direction and defines a side of the clamping extension, the side of the clamping extension constituting a stop for the flange.

A gas bag for a vehicle occupant restraint system comprises a gas bag wall, which in the unfolded state of the gas bag () delimits an indentation () with an orifice () or an opening, and a closure piece () fastened to the gas bag wall, which in the inflated state moves in front of the orifice (:) of the indentation or in front of the opening and covers it. The closure piece () is formed from at least two covering pieces, arranged one over the other, overlapping each other, which respectively have a margin section which is not fastened to the gas bag wall.

An airbag module comprises a housing and an airbag that is arranged in the housing and, at least in sections, folded into a package. A deflection device is provided for the package. The deflection device, the housing and the package are coordinated with each other in such a way that the folded package emerges from the housing in a first direction and is then deflected by means of the deflection device by a predefined angle. There is also proposed a steering wheel including such an airbag module.

The humidifying device for a fuel cell has a membrane, one side of which is exposed to cathode exhaust gas of a fuel cell for extracting water vapor from the exhaust gas. A connecting element connects the other side of the membrane to an anode or cathode gas supply to the fuel cell. In operation, water vapor permeates through the membrane and passes on through the connecting elements to humidify the gas being supplied to the fuel cell. A vacuum pump may additionally be provided to enhance the extraction of water vapor from the exhaust gas. A no metering unit allows accurate metering of the humidity of the cathode or anode gas supply.

A fuel tank, in particular for fuel-cell systems, which can feed fuel into a system via a mechanism without a pump or the like. This is achieved by a fuel tank with a fuel cavity of variable size and a mechanism for compressing the fuel cavity. The fuel cavity is preferably bounded by a cylindrical inner wall of the fuel tank, by a circular end surface of the fuel tank and by a circular, displaceable intermediate wall. The intermediate wall is forced essentially in the direction of the fuel cavity by a spring and has a form fit with the cylindrical inner wall. A feed device and a discharge device allow incorporation in a fuel line. The system also includes a control device and a method for this fuel container, which is thus enabled to have the following operating states: A. fuel-cell system is switched on: discharge valve open, feed valve closed; B. fuel-cell system is in operation: discharge valve open, feed valve open; C. fuel-cell system is switched off: discharge valve closed, feed valve open; and D. fuel-cell system is off, fuel cavity is full: discharge valve closed, feed valve closed.

In an electric motor intended to be fixed to a printed circuit board, provision is made for it to have at least one expanding dowel ( ), for it to be possible for the motor ( ) to be fixed to a printed circuit board ( ) by the expanding dowel or dowels ( ) being expanded, and by it being possible for the expanding dowel or dowels ( ) to be secured at least by a pin ( ).

A fuel cell system which has a fuel cell with a supply line and a discharge line for a fuel as well as a supply line and a discharge line for an oxidizing agent. Also provided is a fuel tank which contains, for example, benzene or methanol for producing the fuel for the fuel cell. To avoid the release of hydrocarbons from the fuel contained in the tank, a filter element, for example an active carbon filter, is connected to the fuel tank. To be able to regenerate the filter element, the filter element is connected to the discharge line for the oxidizing agent and/or the discharge line for the fuel. The filter element is regenerated by the flow of exhaust gas from the fuel cell. The filter element is preferably connected via a connecting line to a burner, with the result that the hydrocarbons taken up by the flow of exhaust gas can be burned in the burner. Furthermore, by designing the fuel cell system appropriately, a leakage diagnosis can also be performed in the fuel tank.

A coil assembly has a coil form on which the coil winding is arranged as well as a method of contacting the coil assembly on a support member. The coil assembly is easy to produce and also permits electrical contacting, namely, the provision of electrical contacts between terminals of the coil and an external circuit in a simple and reliable manner. The coil assembly has a coil form on which two contact feet are arranged, the ends of the coil winding being fastened to the respective contact feet.

An electric motor has two exciter windings, independent of each other, on a stator, by which windings a resultant magnetic field can be produced. The motor includes a permanently magnetized rotor which has at least one pair of poles, the rotor changing its position as a function of the magnetic field, and the rotor being arranged axially on a rotor shaft. In the case of an electric motor which is of a small size and easy to manufacture, the stator is developed with several arms, and has an opening present at the center to receive the rotor. The individual arms are arranged around the opening and, there are, two pairs of opposite arms. The opposite arms are so bent towards each other so that, upon their receiving a respective exciter winding, they produce magnetic vectors which are perpendicular to each other.
