摘要:
The invention relates to an airbag module having a gas generator, particularly a tubular gas generator, comprising a number of outflow openings, which are distributed over the circumference thereof and provided for gases produced after it has been triggered. The invention provides that at least one of the outflow openings inside the gas generator can be closed during installation or after installation in the airbag module, and that the gas generator is fixed inside a module housing that has a closing element in the area of each opening of the gas generator to be closed.

A device for attaching a steering wheel hub to a steering wheel column, while simultaneously fixing a contact unit to the steering wheel, includes a fastener that has a head part engaging in the hub and a shank that engages partially in the hub and partially in the shaft. In a locked position, the fastener engages a recess in the contact unit to prevent the steering wheel hub from rotating relative to the stator of the contact unit. In an unlocked position, the fastener partially engages the hub, partially engages the column, and disengages from the recess in the contact unit to fixedly connect the hub to the column and allow the hub, and therefore the rotor of the contact unit, to rotate.

An annular airbag is disclosed, of the type where the center piece (12) of the steering wheel cover (11) (mostly embodied as the emblem of the vehicle producer) remains in place during the unfolding process. In order to prevent a vehicle occupant impacting the hole arising above the center piece with an inflated airbag, the tubular region (17) of the airbag above the center piece is embodied such that the cross-sectional area thereof in the inflated state reduces in the direction of the upper plate of the airbag from the center piece (12). The above is achieved, for example, by means of a special forming of the tubular region, by provision of pockets (21) and/or folds (31), the use of special materials, a special fixing of the airbag to the airbag module (9), or the fitting of tension straps (50).

A method for folding an airbag for an airbag module is characterized in that an empty airbag is spread out and gathered in towards a center to give a folded airbag. The airbag is gathered inside a fixed vertical profiled section having a top and a bottom separated by a distance corresponding to the predetermined height of the folded airbag. Only a few gathering tools and only a few operations are necessary to gather the airbag. A device for carrying out the method is characterized by a lower part on which the airbag is spread out flat and an upper part separated from the lower part by a distance that corresponds to the vertical profile required for the gathered airbag. Gathering tools are mounted between the upper part and the lower part so that they surround the airbag and so that their position relative to the airbag can be changed.

An airbag, a process for folding same and an apparatus for carrying out the folding process are disclosed. In order to produce a folded airbag as well as a process and apparatus for manufacturing same which ensure that the airbag can unfold very quickly without obstruction evenly where possible in all directions when the associated gas generator is activated, the airbag has main fold lines which run at least in part along closed tracks around an imaginary center on the substantially empty spread-out airbag. The corresponding process ensures such a path of the main fold lines and the apparatus according to the invention has folding elements which are movable relative to each other and which have projections directed towards each other in the direction of movement wherein each projection or group of projections defines a closed track running round a center wherein tracks extending from inside to outside are provided at increasing distance from the center.

A steering wheel assembly for a motor vehicle comprising a steering wheel that can be mounted rotatably about a steering axle on a motor vehicle is provided. The steering wheel assembly comprises an airbag module disposed in a pre-determinable use position on the steering wheel, and an adjusting device disposed on the steering wheel assembly. Said adjusting device is adapted and provided for adjusting the spatial position of the airbag module relative to the steering wheel for the purposes of compensating for tolerances perpendicular to the steering axle. In the process, the adjusting device comprises adjusting means for generating an adjusting force that has at least one force component along the adjusting direction of the airbag module and also a guide device for guiding the airbag module along the adjustment direction thereof.

The invention relates to an airbag module for a motor vehicle comprising an airbag, a gas generator for inflating the airbag, and a housing for accommodating both the gas generator and the airbag. According to the invention, the airbag (1) and the gas generator (2) are arranged on opposite sides (30a, 30b) of a wall (30) of the housing (3).
摘要:
A method and device for folding an airbag having a inner main fold and an outer main fold in a folded state. The airbag is fixed to a working surface, extended along a longitudinal axis away from the working surface, and fixed in the area of the inner or outer main fold. The airbag is then expanded, or contracted, to form the outer or inner main fold, respectively, and then compressed toward the working surface. A shaping body is preferably inserted into the airbag through an inflation opening to extend the airbag so that a folding element may activated to retain the airbag against the shaping body to form the inner or outer main fold.
摘要:
A vehicle passenger safety method in which a gas bag in an airbag module is inflated in between the passenger and parts of the vehicle when a crash occurs. The cover of the gas bag moves away from the passenger before the gas bag is inflated. Preferably, the gas bag and a diffuser, located in between an inflating device and the gas bag, also move away from the passenger. Compressed gas is released from the inflating device into the gas bag only when the above mentioned groups of components have been placed in a set position.
