Abstract

In an aspect, a crash bag is provided, which includes an impact structure and an outlet valve. The impact structure has a first bag wall partially defining a first bag air chamber having an inlet for receiving pressurized air, and having a first operating pressure, and a second bag wall partially defining the first bag air chamber and partially defining a second bag air chamber having an inlet for receiving pressurized air and that has a second bag air chamber operating pressure. The outlet valve discharges air from the second bag air chamber upon an impact on the impact structure. The second bag air chamber includes fluidically connected projections that are adjacent one another. The first bag wall is positioned atop the projections and extends across the projections such that the operating pressure in the first bag air chamber is applied to all the projections.

Dependent claims

A crash bag, comprising:

an impact structure having a first bag wall at least partially defining a first bag air chamber that has a first bag air chamber inlet for receiving pressurized air, and a first bag air chamber operating pressure;
and
a first outlet valve having a first valve inlet in fluid communication with the first bag air chamber and a first valve outlet, and having a first peripheral valve wall that is flexible, wherein the first peripheral valve wall has an inner face that defines a first outlet valve passage through the first outlet valve between the first valve inlet and the first valve outlet, wherein the first peripheral valve wall has an outer face that is in a first valve air chamber having a first valve air chamber operating pressure,
wherein, in a setup state the first valve air chamber operating pressure is greater than the first bag air chamber operating pressure so as to drive a first length of the inner face of the first peripheral valve wall into engagement with a second length of the inner face of the first peripheral valve wall so as to inhibit air leakage from the first outlet valve,
wherein, when in the setup state, an impact at a first kinetic energy on the impact structure increases the first bag air chamber operating pressure sufficiently to drive a first portion of the first length of the inner face of the first peripheral valve wall away from the second length of the inner face of the first peripheral valve wall so as to facilitate air leakage through the first outlet valve passage,
and wherein, when in the setup state, an impact at a second kinetic energy on the impact structure that is higher than the first kinetic energy, increases the first bag air chamber operating pressure sufficiently to drive a second portion of the first length of the inner face of the first peripheral valve wall away from the second length of the inner face of the first peripheral valve wall so as to facilitate air leakage through the first outlet valve passage, wherein the second portion of the first length is greater than the first portion of the first length.

A crash bag, comprising:

an impact structure that includes a first bag air chamber that has a first bag air chamber inlet for receiving pressurized air, and that has a first bag air chamber operating pressure;
a first outlet valve positioned for discharging air from the first bag air chamber upon an impact on the impact structure by a user;
a safety peripheral structure that includes a second bag air chamber that has a second bag air chamber inlet for receiving pressurized air and that has a second bag air chamber operating pressure;
and
a second outlet valve positioned for discharging air from the second bag air chamber upon an impact thereon by the user,
wherein the safety peripheral structure extends along a periphery of the first bag air chamber, wherein the second bag air chamber is divided into a plurality of peripheral subchambers that are separated from one another by a plurality of dividers, wherein each of the plurality of dividers has a pass-through aperture, wherein the pass-through aperture on a first divider from the plurality of dividers is spaced sufficiently to be free of any overlap with the pass-through aperture on a second divider from the plurality of dividers that is subsequent to the first divider, and wherein the pass-through aperture on the second of the plurality of dividers is spaced sufficiently to be free of any overlap with the pass-through aperture on a third divider from the plurality of dividers, which is subsequent to the second divider.
