An airbag unit having an airbag and at least one inflator. The airbag unit is especially suitable for preventing an element located outside the passenger compartment of a vehicle from intruding into the passenger compartment during an accident. The airbag is made of a hose formed of a one-pieced woven element extending from a first end to a second end. The hose is bent or folded, such that two parallel sections () of the airbag are formed with each section () enclosing a chamber. The airbag is very robust and can be designed such that in its deployed state its thickness is large in relation to its volume.

Airbag unit and motor vehicle

A side airbag unit for a vehicle seat including a generally cylindrical gas generator unit having a longitudinal axis. The vehicle seat has a backrest with a front surface and a side surface. In order to achieve the result that the airbag requires little additional space and nevertheless is relatively easy to mount on the vehicle seat, the longitudinal axis extends generally parallel to the front surface and perpendicular to the side surface of the vehicle seat.

Vehicle seat unit

Described is a gas generator unit comprising of a cylindrical gas generator (), the lateral surface () of which demonstrates emission holes () arranged in a thrust-neutral manner within a ring-shaped area (), and a deflector element (), which is rigidly connected to the gas generator () and is made of a heat resistant material and at least surrounds the ring-shaped area () at least partially. To make the gas generator harmless in the event of a fire, the deflector element () demonstrates, in an inflow area () opposite the ring-shaped area (), borings (), which are sealed by at least one blocking element () made of a meltable or combustible material, the borings being arranged in such a manner that the gas generator unit is thrust-neutral in the absence of the blocking element ().

Gas generator unit

An airbag for use in motor vehicles having two or more chambers, which is simple to manufacture, low-cost and not susceptible to disturbances. The airbag is configured such that the chambers can have different internal pressures in case of airbag activation since a dividing seam between the chambers of the airbag is configured to act as a gas stream divider and direct differing quantities of gas into the chambers.
