    • A method and apparatus for compactly folding an airbag of an airbag apparatus adapted for use in motor vehicles. One side of the airbag has a central opening for connection to a gas generator, with a reinforcement preferably around the central opening. The airbag is laid out flat, is held at its center and the zones lying radially outside of the center are turned in around an axis extending at least substantially perpendicular to the flatly laid out gas bag through the central firm holding zone in at least one direction of rotation until a compact airbag package is formed. One embodiment of the invention includes radially disposed axial shifting members, which leave a reception space radially inward and which displace the flexible material of the flatly laid out airbag alternatively, as seen in the circumferential direction in the one or other axial direction before the airbag is wound up. This is done in such a way that the airbag adopts a corrugated or zigzag like course when seen in the circumferential direction, with the wave-shape and wavelength being selected such that with a synchronous rotation of the axial shifting members about the axis, the zones of the wave-like or zigzag folded airbag lying radially outside of the central firm holding zone are at least substantially taken along in the circumferential direction by the axial shifting members. The winding takes place until the compact airbag package is formed and located radially within the axial shifting members with the formation of radial folds pointing alternatively in opposite axial directions in the receiving space.

    • The invention relates to a method for accommodating an airbag of an airbag apparatus into a container. The folding method employed allows the airbag to folded into a small container, yet ensures that the airbag will inflate in a substantially uniform and jerk-free manner. The method is still fairly cost effective. A preferred embodiment encompasses inserting a first plunger into an opening in a lower half of the airbag such that it pushes the upper part away from the lower part. The upper part is then clamped between the first plunger and a second plunger. Next, the airbag is folded upward such that a plurality of radial folds is created, which are then folded inward. A hollow die is then placed over the folded airbag. The upper end of the airbag and a central portion of the airbag are twisted in different directions while a third plunger is placed over the end face of the folded airbag. The third plunger is then used to compress the airbag. The third plunger is then removed while a container is placed over the compacted airbag and the die is removed.
    • 本发明涉及一种将气囊装置的气囊容纳在容器中的方法。 所使用的折叠方法允许气囊折叠成小容器,但是确保气囊将以基本上均匀且无混乱的方式膨胀。 该方法仍然具有成本效益。 优选的实施例包括将第一柱塞插入气囊的下半部分的开口中,使得其将上部部分推离下部。 然后将上部夹紧在第一柱塞和第二柱塞之间。 接下来,气囊向上折叠,使得产生多个径向折叠,然后将其向内折叠。 然后将空心模具放置在折叠的气囊上。 气囊的上端和气囊的中心部分在不同的方向上被扭转,同时第三柱塞被放置在折叠的气囊的端面之上。 然后将第三柱塞用于压缩气囊。 然后在将容器放置在压实的气囊上并移除模具的同时移除第三柱塞。
