An airbag device includes an airbag module that is located behind a multipart dashboard. An opening device opens the multipart dashboard in a manner similar to that of the mouth of a fish. An operating method for an airbag device with an airbag module located behind a multipart dashboard includes opening the dashboard in a manner similar to that of the mouth of a fish before, during, or after the triggering of the airbag device. According to another embodiment, a dashboard includes at least one fabric flap or foil flap which is integrated into the dashboard on at least one side by using detachable retaining devices in order to close an opening in the dashboard. The airbag module is positioned behind the opening in such a way that an airbag opens the retaining devices when it is triggered and emerges through the opening.

Airbag device and method for operating an airbag device

An airbag device includes an airbag module and at least one airbag cover which is connected to a piston via pulling devices. The piston can be subjected to pyrotechnical action in order to produce a linear movement of the piston. When the piston is caused to move, the airbag cover moves from a closed position, in which the airbag cover blocks an exit path of the airbag out of the airbag module, into an open position, in which the airbag cover clears the exit path of the airbag out of the airbag module. The piston is forcibly guided to perform a helical movement so that the piston, when caused to move, performs a rotational movement during its linear movement, thus winding up the pulling devices. A method for operating an airbag device is also provided.

Airbag device and method of operating an airbag device

An airbag device includes a gas generator and an airbag to be accommodated behind at least one cover that can be displaced from a closed position, in which it is integrated into the vehicle's paneling, into an open position, in which it is disposed behind the paneling, when the airbag device is activated by driving devices. In the open position, the cover does not substantially project beyond the vehicle's paneling in the direction toward a passenger. The driving devices include at least one rolling piston that can be rolled in a guide chamber along a rolling path from a starting position into an end position when being subjected to compressed gas. The rolling piston thus causes the cover to move from the closed position to the open position. A method for operating an airbag device is also provided.

Airbag configuration and method for operating an airbag configuration

An airbag arrangement has an airbag flap which is arranged in a closed position in an airbag outlet opening in a vehicle interior paneling, and which, as a consequence of triggering of the airbag arrangement, can be moved with respect to a vehicle occupant out of the airing outlet opening into an open position behind the vehicle interior paneling by driving devices. The airbag flap is held in its closed position in the airbag outlet opening in a form-fitting manner by engagement devices and locking devices. The engagement devices are assigned only to one side of the airbag flap and the airbag outlet opening, and as a consequence of triggering of the airbag arrangement the locking devices can be released by the driving devices. A vehicle interior paneling and an operating method for an airbag arrangement are also provided.

Airbag device and operating method for it as well as vehicle interior paneling with it

An airbag system includes at least one cover configuration movable from a closed position to an open position. An airbag is disposed behind the at least one cover configuration when the at least one cover configuration is in the closed position. The airbag is configured to expand when being filled with gas. A control device includes a gas generating configuration and a mechanical configuration. The gas generating configuration and the mechanical configuration operate as a drive configuration for moving the at least one cover configuration from the closed position to the open position for allowing the airbag to expand.

Airbag system with a controlled cover configuration

The invention pertains to an airbag device for a motor vehicle with at least one cover flap, behind which is a gas generator with which a gas bag can be inflated, and also moving drive devices that can be actuated by and are connected to each cover flap, where the latter is moved before or during triggering of the gas generator within the airbag device or within a part of the motor vehicle containing the airbag device. Furthermore, it is provided that the drive devices contain at least one piston running within a channel.

Airbag device

The invention relates to an air bag arrangement in vehicle, having a gas bag which, as the result of a triggering by a sensor, can be inflated with gas by a gas generator and, during the inflating, can be advanced into an interior of the vehicle, the gas generator having at least two driving stages with propellant charges which can be ignited in a time-related succession and of which the first propellant charge is ignited by a triggering by a sensor and the second propellant charge being ignited facultatively when the gas bag moves beyond a defined advancing position. In addition, the invention relates to a triggering process for an air bag arrangement, wherein, as a function of the driving situation, a first stage of at least one gas generator or at least a first gas generator is triggered, the gas generated in this manner is guided into at least one gas bag for its partial filling, at least one possible hindering of the expansion of the gas bag is detected, and in the case of an unhindered expansion of the gas bag at least one additional stage of the gas generator or at least one additional gas generator is triggered for the further or complete filling of the gas bag.
