  • Publication number: 20130270802
    Abstract: A knee airbag module (200) has an airbag (201), an inflator (206) and a housing (202). The knee airbag module (200) is a self-contained assembly for mounting to a vehicle frame part (108) under the instrument panel (106). The housing (202) contains the airbag (201) and inflator (206) within a hollow interior of the housing formed by a first housing part (300) and a second housing part (302). The first and second housing parts are joined together. The housing (202) includes a deployable door cover (220) formed in the second part that articulates about a hinge (222) as the airbag (201) is inflated. The airbag (201), when inflated, extends upward relative to the lower portion of the instrument panel (106) between the instrument panel (106) and an occupant's knees (120). The door cover (220) is partially separated from the second housing part (302) by a tear seam (320). The hinge (222) is near a portion of the tear seam (320).

  • Patent number: 8556294
    Abstract: An airbag inflator has a primary igniter and a secondary igniter. The primary igniter ignites an ignition enhancer material, which in turn ignites a primary supply of a gas generant material in a first chamber. A secondary supply of the gas generant material is located in a second chamber that is closed and is not in contact with any ignition enhancer material. Activation of the secondary igniter does not ignite the secondary supply of gas generant material, but does cause the second chamber to be opened. Combustion products from the primary supply of gas generant material enter the chamber and ignite the secondary supply of the gas generant material.

  • Patent number: 8491005
    Abstract: An inflator for producing inflation gas from a propellant has a housing for storing the propellant, a diffuser for attachment to the inflator housing and a sealing member. The diffuser has one or more open passages for passing inflation gas upon ignition of the propellant and a plurality of sealed passages oriented opposite to the one or more open passages. The sealing member covers the sealed passages. The sealing member is consumed when exposed to an open flame thereby opening the sealed passages to vent inflation gases opposite the opposed one or more open passages to create a thrust neutral exhaust upon an inadvertent ignition of the propellant due to exposure to fire.

  • Patent number: 8429799
    Abstract: An improved seat belt buckle assembly (10) for use with a tongue (2) of a seat belt during use, locking the latch (20) and control lever (40) in the unlatched position, but when the buckle is latched and exposed to a rapid deceleration a mass (60) slides compressing a lower spring (52) into the frame (12) moving the mass (60) to occupy the space directly under stop surfaces (45) of control lever arms (42, 43) of a control lever (40) blocking downward movement and preventing a locking bar (18) from leaving a horizontal portion of L-shaped slots (9) preventing movement of the latch (20) into the unlatched position. The mass (60) is preferably attached to an ejector (30), the ejector (30) fits into a slot (62) in the mass (60) and extends into a pair of horizontal slots (31) on the frame, one horizontal slot (31) being on each vertical side (6, 7) of the frame (12). The ejector (30) secures the mass (60) in the frame (12) limiting the mass (60) to horizontal forward and rearward sliding movements.
