Embodiment Construction

[0038] first reference figure 1 , which shows a balloon 1 suitable for use in the method of the invention. The particular airbag 1 shown is a so-called side airbag, a type of airbag to be mounted on the side of a vehicle seat for opening between a seat occupant and a side door or dashboard of a motor vehicle. However, it should be understood that the present invention is not limited to the type of side airbag shown, but can be used to pack virtually any type of airbag. Indeed, it has been found that, as explained in more detail below, the airbag unit and method of the present invention provide significant benefits for an inflatable curtain type airbag. Further, it should also be understood that the airbag 1 is shown in basic form in order to clearly illustrate the general concept of the invention. Other more complex airbag configurations can also be packaged by the method of the present invention.

[0039] The airbag 1 may be formed from two sheets 2, 3 of substantially ide...

Abstract

There is disclosed an airbag unit (21) for a motor vehicle safety device. The unit (21) comprises an inflatable airbag (1) formed of flexible material and provided in a rolled and / or folded package (8), which is held under compression by a cover (9) extending around at least part of the package (8). The cover (9) is formed of a moulded pulp material (13) and is configured to impart a predetermined stable shape to the unit (1). A method of packaging an airbag (1) in such a manner is also disclosed.

Description

technical field [0001] The present invention relates to an airbag unit for motor vehicle safety equipment, and a related method of packaging an airbag for motor vehicle safety equipment. Background technique [0002] It is now known to provide motor vehicles with one or more inflatable airbags to provide protection to occupants in the event of an accident involving the motor vehicle, and also arrangements to provide protection to pedestrians. Typically such airbags are constructed of flexible fabric, although some arrangements use other flexible sheet materials, such as plastic materials. Airbags can take different forms, for example, so-called driver's airbags, which are typically inflated from within the hub of the steering wheel of a motor vehicle in the event of a frontal collision to provide protection to the driver of the vehicle; The windows of the vehicle are opened downwards to protect the occupant in the event of a side collision or rollover accident; in order to ...
