In a protective helmet comprising a rigid shell having a lower periphery and a suspension system, which may have two crossed straps mounted within the rigid shell, at spaced intervals around a lower periphery of the rigid shell, an array of inflatable pads is carried by the suspension system, within the rigid shell, above the lower periphery. The inflatable pads are joined by and between two fabric sheets. If the suspension system has two crossed straps, as preferred, some of the inflatable pads are disposed directly below the cross ed straps, between a central region of the rigid shell and the lower periphery, while another of the inflatable pads is disposed in the central region. The crossed straps may extend through slits in the fabric sheets. The respective pads are inflated with a suitable gas, such as air, with a suitable liquid, such as water, with a suitable foam, or with a suitable gel.
