Abstract
An apparatus (10) comprises an inflatable vehicle occupant protection device (14). The protection device (14) has a panel structure (52). The panel structure (52) has an open end portion (70) that is axially separated from a portion for attaching a body structure (50). At least one pair of axially aligned apertures (72 and 74) extends through the panel structure (52). The apparatus (10) further comprises a retainer (60) for supporting the open end portion (70) of the panel structure (52) of the protection device (14). The panel structure (52) is coiled around the retainer (60) such that the axially aligned apertures (72 and 74) become aligned on a same side of the retainer (60).

Apparatus comprising:
- an inflatable vehicle occupant protection device having a panel structure, said panel structure having an open end portion that is axially separated from a portion for attaching a body structure;
- at least one pair of axially aligned apertures extending through said panel structure;
- a retainer for supporting said open end portion of said panel structure of said protection device;
- said panel structure being coiled around said retainer such that said axially aligned apertures become aligned on a same side of said retainer.
Apparatus comprising:
- an inflatable vehicle occupant protection device;
- an inflator having a source of inflation fluid, said inflator being actuatable to release inflation fluid into said protection device to inflate said protection device;
- a sensor for sensing a vehicle crash condition and actuating said inflator in response to said vehicle crash condition;
- and
- a retainer for supporting a portion of said protection device,
- said portion of said protection device being coiled around said retainer, said coiled portion forming overlapping plies comprising an inner ply and an outer ply in contact with each other on the same side of the retainer, said outer ply moving relative to said inner ply upon inflation of said protection device which tightens said coiled portion around said retainer.
