Embodiment Construction

[0033] figure 1 The right front side of the motor vehicle (in particular a passenger car) is shown prominently and schematically. The body 10 encloses a motor compartment 12 and a passenger compartment 14 . Wheel housings 15 are adjacent to motor compartment 12 and passenger compartment 14 . Located inside the wheel housing 15 is a wheel 16 from which an axle 17 and steering linkage 18 extend.

[0034] In order to prevent the wheels 16 from penetrating into the passenger compartment 14 in the event of a frontal or side collision, an airbag unit 20 is provided, the airbag 24 of which is placed between the wheels 16 and the passenger compartment 14 . as will subsequently be based on Figure 3-Figure 5 As depicted, the airbag 24 comprises two parts 24a, 24b, each part 24a, 24b enclosing a chamber. Each of these chambers is in gas flow connection with an inflator (ie, gas generator). figure 1 and 2 One of these gas generators, the first gas generator 22, is shown in .

Abstract

An airbag unit is described comprising an airbag and at least one inflator. The airbag of such an airbag unit is particularly suitable for preventing elements located outside the passenger compartment of the vehicle from penetrating into the cabin during an accident. The airbag is made of a hose extending from a first end to a second end, the hose comprising a one-piece braided hose element extending from the first end to a second end. Two ends. The hose is bent or folded so that two parallel sections (24a, 24b) of the airbag are formed, each section (24a, 24b) enclosing a chamber. The airbag is very durable and can be designed such that its thickness is large relative to its volume in its deployed state.

Description

technical field [0001] The invention relates to an airbag unit and a motor vehicle with such an airbag unit. Background technique [0002] Airbag units are widely used in today's automotive technology. An airbag unit often comprises at least one airbag surrounding at least one chamber, and at least one inflator, in most cases in the form of a gas generator, for filling the at least one chamber in order to deploy the airbag. [0003] Currently, most airbag units are used to protect an occupant (driver or passenger) seated inside a passenger cabin of a motor vehicle. This means that the airbag of this type of airbag unit deploys into the passenger compartment in order to restrain the occupants. Therefore, the airbag of this type of airbag unit must be relatively soft and the airbag usually must contain a ventilation device so that the kinetic energy can be dissipated. [0004] So-called pedestrian airbags have recently been proposed, which serve to protect pedestrians invol...
