Techniques for controlling a protection apparatus are provided. An example method includes detecting an offset collision or diagonal collision, and activating a suitable protection apparatus for protecting the side or head of a passenger at a timing in accordance with the degree of collision. An example controller may include a level calculation part for calculating a level of a front face collision, a ΔV.sub.offset calculation part for making an offset adjustment of a speed (ΔV), and a determination part for determining an offset collision or diagonal collision based on the level of the front face collision and the ΔV.sub.offset.

An airbag module for an automotive vehicle is disclosed. The airbag module comprises a folded inflatable airbag, a fastening element for mounting the airbag on the vehicle, a mounting jacket in which the folded airbag is received and fixed, as well as an elongate flexible holding strap for positioning the airbag in its deployed inflated state. The holding strap extends from a first strap end fastened on the airbag to an opposite second strap end to which the fastening element is attached. In the folded state of the airbag, the holding strap is connected to the mounting jacket or is received in the mounting jacket.

Proposed is a roof airbag that is disposed at the roof of a vehicle and is deployed into an interior space of the vehicle. A bracket is provided to the roof. An inflator is connected to the bracket and configured to discharge an inflation gas when operated. An airbag cushion is provided to an airbag cover connected to the bracket in a foldable way and deployed into an interior space of the vehicle by the inflation gas supplied by the inflator. A tether is configured such that one end thereof is fixed to the roof side, and the other end of which is connected to the airbag cushion. The tether supports the airbag cushion so that, when the airbag cushion is deployed, the airbag cushion is deployed toward a seat.

The disclosure relates to an airbag module that comprises an inflatable airbag, an inflator for inflating the airbag and a plurality of securing units for attaching the airbag module to a vehicle. The airbag has a C-shaped configuration including two juxtaposed legs in an imaginary cross-sectional plane that is transverse to its longitudinal extension. The disclosed design of the airbag is configured to improve deployment behavior such that in a mounting situation of the airbag 10 a central plane defined between the two legs intersects a vertical plane extending through the longitudinal extension of the airbag. A manufacturing method for an airbag module is disclosed.

In a method of folding a curtain-type side airbag to form an elongate airbag package which defines a longitudinal direction, in one folding step at least portions of the side airbag are rolled around a first winding axis. In another folding step, at least portions of the side airbag are rolled around a second winding axis which is at an angle between 0° and 180° with the first winding axis.
