Abstract
An inflatable bolster for use in a passenger compartment of a vehicle comprises a hollow body having a first wall having a central area and a circumferential area surrounding the central area, a second wall opposite the first wall, and an air chamber formed between the first and second walls. The inflatable bolster also comprises an inflator for injecting a pressurized fluid into the air chamber which is mounted to the hollow body. The inflatable bolster also comprises a plurality of concentric extension pleats formed in the first wall. The extension pleats extend around a major part of the circumferential area. The extension pleats contact the second wall at a plurality of contact points which are distributed across the second wall. The plurality of contact points is sufficient in number to at least partially suppress audible vibration of the second wall.
