摘要:
A gas bag module (10) includes a gas bag (12), the gas bag having a front wall (14) facing an occupant (16) in an inflated state of said gas bag (12) and being engaged by a first end (18) of a destructible retaining element (20), the retaining element (20) at least partially preventing an unhindered motion of the front wall (14) when the gas bag (12) is inflated. The gas bag module further includes a gas generator (22) for filling the gas bag (12), the gas generator (22) having a first discharge section (24) for a through flow of a first quantity of gas. The gas generator (22) has a separate, second discharge section (26), 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 (20) through the second discharge section (26) so as to cause a destruction of the retaining element (20).

An assembly of a steering wheel base body (12) and a gas bag module (14), the gas bag module (14) being able to be detachably latched with the steering wheel base body (12). A group of first latching elements (18; 318) is provided on the gas bag module (14) or the steering wheel base body (12), and at least one second latching element (22; 322), able to be brought into reversible locking engagement with the first latching elements (18; 318), is provided on the steering wheel base body (12) or the gas bag module (14). When the assembly (12, 14) has been put together, the first latching elements and the at least one second latching element (18, 22; 318, 322) are arranged so as to be movable with respect to each other in an unlocking direction (R; R′). The first and second latching elements (18, 22; 318, 322) are designed such that through a movement of the second latching element (22; 322) relative to the first latching elements (18; 318) in the unlocking direction (R; R′) all latching connections (18, 22; 318, 322) are released simultaneously in a non-destructive manner.
摘要:
A gas bag of a restraint device has a first wall part (14) and a second wall part (16), the first wall part (14) and the second wall part (16) being joined at an attachment section (18) by an adhesive. A bonding agent (20) is added to the attachment section (18) in order to improve the adhesive connection.
摘要:
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.
摘要:
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.
摘要:
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 (4), for it to be possible for the motor (1) to be fixed to a printed circuit board (6, 32) by the expanding dowel or dowels (4) being expanded, and by it being possible for the expanding dowel or dowels (4) to be secured at least by a pin (7).
摘要:
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.
摘要:
A gas bag for a vehicle occupant restraint system has a pre-cut section forming a lower part, and an upper part connected to the lower part. The pre-cut section forming the lower part, when spread out flat, is substantially one of trapezoidal and ring segment-shaped, and the lower part is funnel-shaped in the inflated state of the gas bag.
摘要:
A gas bag module for a vehicle occupant restraint device includes a rigid component (10). The rigid component (10) has a discharge opening (12) formed therein through which gas can escape. The discharge opening (12) is covered by a flat covering part (14). The flat covering part (14) includes an extensible material and has at least one hole (16).
摘要:
A vehicle steering wheel includes a gas bag module which has a gas generator (14) for filling a gas bag. The steering wheel has at least one discharge opening (12; 34) formed in a rigid component (10) of the steering wheel or of the gas bag module, through which opening gas generated by the gas generator (14) can partially discharge. The steering wheel further includes at least one electrically controllable closure element (14; 26; 28), by which the discharge opening (12; 34) can be opened. The closure element (14; 26, 28) is designed and controllable such that it is movable several times into an open position and into a closure position.
