Embodiment Construction

[0071] The invention will be illustrated by way of examples below. It is to be understood, however, that the included examples are included merely to illustrate the principles of the invention and not to limit the scope of the invention, which is defined by the appended claims. Details from two or more embodiments may be combined with each other.

[0072] figure 1 with 2a - b schematically shows an airbag assembly 102 used as a side airbag assembly according to the prior art. figure 1 is a side view with the airbag of the airbag assembly 102 removed for better visibility. Figure 2a -b is a top sectional view where the airbag 104 is visible. The airbag assembly 102 includes a gas generator 106 coupled to a seat frame 108 of a vehicle seat 110 . Once the gas generator 106 is activated, gas flow expands radially away from the top 112 of the gas generator 106 in multiple directions. The airbag 104 is intended to protect an occupant 114 seated in the seat 110 from being stru...

Abstract

The invention relates to an airbag assembly (2) for a vehicle, the airbag assembly comprising: deployed airbags (4, 4', 4'', 4'''), the airbags having a packaged state and a deployed state, suitable for supplying gas to deploy the airbag from a packaged state to a gas generator (6) in a deployed state, the gas generator being adapted to emit a flow of gas substantially in a preselected direction at least during initial deployment of the airbag, wherein when in In its packaged state, a portion of the airbag forms a starting pocket (20) comprising two panels (22, 24) with a middle apex (26), the starting pocket being positioned with the middle apex aligned with a preselected orientation , such that the initial pocket is the first to receive airflow during initial deployment of the airbag, thereby deploying the initial pocket in a preselected direction. The invention further relates to a vehicle seat (10) comprising such an airbag assembly and a method of packaging the airbag.

Description

technical field [0001] The invention relates to a safety airbag assembly. The invention also relates to a vehicle seat comprising such an airbag assembly and a method of packaging a vehicle airbag. Background technique [0002] Inflatable airbags are commonly used to protect occupants in vehicles such as cars, buses, trucks or vans in the event of an accident. The airbag assembly includes a deployable airbag and a gas generator configured to supply gas to deploy the airbag. [0003] Known types of airbag assemblies according to the prior art incorporating figure 1 and 2 are as follows, wherein the airbag assembly is used as a side airbag assembly. Once the gas generator is activated, gas flow expands radially away from the top of the gas generator in a number of arbitrary directions. During deployment, the airbag pushes against support mechanisms attached to the seat frame and the seat frame itself, and expands laterally and longitudinally within the vehicle. The airbag...
