1. An airbag comprising:
- an airbag body defining an interior of the airbag; and
at least one substantially sinusoidal seam joining together portions of the airbag body to partition the airbag interior into a plurality of fluidly communicating chambers, the seam being constructed so as not to tear during inflation of the airbag.

Abstract
An airbag (10) for a vehicle occupant restraint system. The airbag includes an airbag body (12) defining an interior (15) of the airbag (10). A series of substantially sinusoidal seams (20) join together portions of the airbag body (12) to partition the airbag interior (15) into a plurality of fluidly communicating chambers (22). It is believed that characteristics of the airbag (10) during inflation and after inflation may be controlled by varying the characteristics of the sinusoidal seams (20).
