Abstract
Abstract A bleed cap for a vehicle air cushion inflator includes an elongated receptacle whose ends define first and second aligned apertures that carry respective annular seal arrangements. The seal arrangement at the first end of the receptacle is adaptable to seal with the inflator and encompass the inflator outlet so that pressurized gas discharged from the inflator is received by the receptacle. A headed attachment bolt with an elongated shank is received within the receptacle extending between the seal arrangement at the second aperture and an externally threaded member at the inflator outlet. The unheaded end of the bolt includes a threaded counterbore that threads onto the externally threaded member so as to seal the headed end of the bolt against its adjacent seal arrangement and to secure the cap to the inflator. A passage in the bolt communicates the interior of the receptacle with the environment and includes an outer frustoconical end portion that is axially aligned with the shank of the bolt and threaded so as to receive an orificed frustoconical plug for bleeding the pressurized gas received within the receptacle to the environment.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
188 words
A bleed cap for the outlet of a vehicle air cushion inflator, the cap comprising, a generally enclosed receptacle having opposed portions defining first and second apertures in alignment with each other, the receptacle being adaptable to engage the inflator in a generally sealing manner with the first aperture encompassing the inflator outlet so that pressurized gas discharged from the inflator is received by the receptacle, an elongated attachment member received within the receptacle so as to extend between the outlet of the inflator and the second aperture of the receptacle, the end of the attachment member adjacent the outlet being threaded so as to thread to a cooperable threaded member on the inflator, sealing means extending between the other end of the attachment member and the receptacle so as to generally seal this aperture and to secure the cap to the inflator, and a bleed passage defined by the attachment member so as to communicate the interior of the receptacle and the environment through the second aperture of the receptacle such that pressurized gas received by the receptacle from the inflator is slowly bled to the environment.
Claim 2
Dependent Claim
188 words
A bleed cap for the outlet of a vehicle air cushion inflator, the cap comprising, a generally enclosed receptacle having opposed portions defining first and second apertures in alignment with each other, the receptacle being adaptable to engage the inflator in a generally sealing manner with the first aperture encompassing the inflator outlet so that pressurized gas discharged from the inflator is received by the receptacle, an elongated attachment member received within the receptacle so as to extend between the outlet of the inflator and the second aperture of the receptacle, the end of the attachment member adjacent the outlet being threaded so as to thread to a cooperable threaded member on the inflator, sealing means extending between the other end of the attachment member and the receptacle so as to generally seal this aperture and to secure the cap to the inflator, and a bleed passage defined by the attachment member so as to communicate the interior of the receptacle and the environment through the second aperture of the receptacle such that pressurized gas received by the receptacle from the inflator is slowly bled to the environment.
Claim 3
Dependent Claim
204 words
A bleed cap for the outlet of a vehicle air cushion inflator, the cap comprising, an elongated receptacle whose ends define first and second apertures that are aligned with each other, first annular sealing means mounted on the receptacle adjacent the first aperture thereof and adaptable to sealingly engage the inflator while encompassing the inflator outlet so that pressurized gas discharged from the inflator is received by the receptacle, second annular sealing means mounted on the receptacle adjacent the second aperture, a headed attachment bolt having an elongated shank received within the receptacle so as to extend between the inflator outlet and the second aperture, the end of the attachment member adjacent the outlet being threaded so as to thread to a cooperable threaded member on the inflator, the headed end of the bolt sealing with the second annular sealing means as this threading proceeds so as to seal the second aperture and to secure the cap to the inflator, and a bleed passage defined by the bolt so as to communicate the interior of the receptacle and the environment through the second aperture of the receptacle such that pressurized gas received by the receptacle from the inflator is slowly bled to the environment.
Claim 4
Dependent Claim
204 words
A bleed cap for the outlet of a vehicle air cushion inflator, the cap comprising, an elongated receptacle whose ends define first and second apertures that are aligned with each other, first annular sealing means mounted on the receptacle adjacent the first aperture thereof and adaptable to sealingly engage the inflator while encompassing the inflator outlet so that pressurized gas discharged from the inflator is received by the receptacle, second annular sealing means mounted on the receptacle adjacent the second aperture, a headed attachment bolt having an elongated shank received within the receptacle so as to extend between the inflator outlet and the second aperture, the end of the attachment member adjacent the outlet being threaded so as to thread to a cooperable threaded member on the inflator, the headed end of the bolt sealing with the second annular sealing means as this threading proceeds so as to seal the second aperture and to secure the cap to the inflator, and a bleed passage defined by the bolt so as to communicate the interior of the receptacle and the environment through the second aperture of the receptacle such that pressurized gas received by the receptacle from the inflator is slowly bled to the environment.
Claim 5
Dependent Claim
250 words
A bleed cap for the outlet of a vehicle air cushion inflator, the cap comprising, an elongated receptacle whose ends define first and second apertures that are aligned with each other, first annular sealing means mounted on the receptacle adjacent the first aperture and adaptable to sealingly engage the inflator while encompassing the inflator outlet so that pressurized gas discharged from the inflator is received by the receptacle, second annular sealing means mounted on the receptacle adjacent the second aperture, a headed attachment bolt having an elongated shank received within the receptacle and extending between the inflator outlet and the second aperture, the unheaded end of the bolt having a threaded counterbore for threading on a cooperable externally threaded member of the inflator adjacent the outlet thereof, the headed end of the bolt seating with the second annular sealing means as this threading proceeds so as to seal the second aperture and to secure the cap to the inflator, the bolt defining a passage communicating the interior of the receptacle and the environment through the second aperture of the receptacle, the outer end of the passage being axially aligned with the shank of the bolt and having a frustoconical configuration that tapers inwardly and is threaded, and a threaded frustoconical plug threadingly received by the outer end of the passage and defining a bleed orifice in communication with the passage and the environment such that pressurized gas received within the receptacle from the inflator is slowly bled to the environment.
