The suspension has a horizontal band portion for extending around a user's head, and the suspension is positioned within a hardhat shell. At least one hanger is connected to the suspension for securing the suspension to the shell. Each hanger has a hook at a first end of the hanger, a latching surface located towards the middle of the hanger, and a lever arm at a second end of the hanger. At least one mount is formed on the inner surface of the shell. Each hanger is configured to securely engage a respective one of the mounts, with the latching surface of the respective hanger being in frictional engagement with the respective ledge surface of the mount. By manually pivoting the hanger, a user can cause the latching surface to disengage from the ledge surface. ## Claims ### Claim 1 A hardhat comprising: a shell having an outer surface and an inner surface; a suspension comprising a horizontal band that is configured to at least partially encircle a user's head; a hanger connected to the suspension for securing the suspension to the shell, the hanger further comprising: a hook at a first lower end of the hanger; a latching surface located towards a middle of the hanger; a lever arm at a second upper end of the hanger; a mount formed on the inner surface of the shell, the mount having a mount platform toward a first lower end of the mount and a ledge surface at a second upper end of the mount; wherein the hanger is configured to securely engage the mount with the latching surface of the hanger being in frictional engagement with the ledge surface of the mount and the mount platform being in direct facing relation with a surface on the hook, thereby positionally securing the hanger to the shell, and further wherein the first lower end of the hanger is the lower end thereof when the suspension is secured to the shell and the shell is in an upright position. ### Claim 2 (depends on 1) The hardhat of claim 1, the hanger further comprising a support arm having a free portion for connecting the hanger to the suspension, the support arm being connected to the lever arm by a spring. ### Claim 3 (depends on 1) The hardhat of claim 1, wherein the latching surface is formed on a latching body that extends radially outwardly from the hanger when the suspension is secured within a hardhat, and a user can disengage the latching surface from the ledge surface by deflecting the second upper end of the hanger radially inwardly. ### Claim 4 (depends on 1) The hardhat of claim 1, wherein the ledge surface of the mount faces upwardly, and the latching surface of the hanger faces downwardly. ### Claim 5 (depends on 1) The hardhat of claim 1 comprising four hangers, and four mounts spaced about the inner surface of the shell. ### Claim 6 A hardhat for supporting a suspension, the suspension having a horizontal band that is configured to at least partially encircle a user's head, the hardhat comprising: a shell having an outer surface and an inner surface; a hanger configured to be connected to said suspension for securing said suspension to the shell, the hanger further comprising: a hook at a first lower end of the hanger; a latching surface located towards a middle of the hanger; a lever arm at a second upper end of the hanger; a mount formed on the inner surface of the shell, the mount having a mount platform toward a first lower end thereof and a ledge surface at a second upper end thereof; wherein the hanger is configured to securely engage the mount with the latching surface of the hanger being in frictional engagement with the ledge surface of the mount and the mount platform being in direct facing relation with a surface on the hook, thereby positionally securing the hanger to the shell, and further wherein the first lower end of the hanger is the lower end thereof when the suspension is secured to the shell and the shell is in an upright position. ### Claim 7 (depends on 6) The hardhat of claim 6, the hanger further comprising a support arm having a free portion for connecting the hanger to the suspension, the support arm being connected to the lever arm by a spring. ### Claim 8 (depends on 6) The hardhat of claim 6, wherein the latching surface is formed on a latching body that extends radially outwardly from the hanger when a suspension is secured within a hardhat, and a user can disengage the latching surface from the ledge surface by deflecting the second end of the hanger radially inwardly. ### Claim 9 (depends on 6) The hardhat of claim 6, wherein the ledge surface of the mount faces upwardly, and the latching surface of the hanger faces downwardly. ### Claim 10 (depends on 6) The hardhat of claim 6 comprising four hangers, and four mounts spaced about the inner surface of the shell. ### Claim 11 A hardhat suspension assembly configured for being secured within a hardhat shell, the hardhat shell having a mount formed on an inner surface of the shell, the mount having a mount platform toward a first lower end of the mount and a ledge surface at a second upper end of the mount, the hardhat suspension comprising: a suspension comprising a horizontal band that is configured to at least partially encircle a user's head; a hanger connected to the suspension for securing the suspension to the shell, the hanger further comprising: a hook at a first lower end of the hanger; a latching surface located towards a middle of the hanger; a lever arm at a second upper end of the hanger; wherein the hanger is configured to securely engage the mount, with the latching surface of the hanger being in frictional engagement with the ledge surface of the mount and the mount platform being in direct facing relation with a surface on the hook, thereby positionally securing the hanger to the shell, and further wherein the first lower end of the hanger is the lower end thereof when the suspension is secured to the shell and the shell is in an upright position. ### Claim 12 (depends on 11) The hardhat suspension assembly of claim 11, the hanger further comprising a support arm having a free portion for connecting the hanger to the suspension, the support arm being connected to the lever arm by a spring. ### Claim 13 (depends on 11) The hardhat suspension assembly of claim 11, wherein the latching surface is formed on a latching body that extends radially outwardly from the hanger when the suspension is secured within a hardhat, and a user can disengage the latching surface from the ledge surface by deflecting the second end of the hanger radially inwardly. ### Claim 14 (depends on 11) The hardhat suspension assembly of claim 11 wherein the ledge surface of the mount faces upwardly, and the latching surface of the hanger faces downwardly. ### Claim 15 (depends on 11) The hardhat suspension assembly of claim 11 comprising four hangers and four mounts spaced about the inner surface of the shell.
