Abstract:
A gas bag restraining module having a housing (10), an inflation device (12) located in the latter, said inflation device providing a volume of pressurized gas after activation, and having a folded gas bag (50), which has an attachment section fixed to the housing (10) and surrounding an inflation aperture, should be adapted to the use of an inflation device, which is known in the form of a "heated gas inflator". For this purpose, the invention provides that the inflation device has a cylindrical pressurized gas container (12), the housing (10) is formed with a trough-shaped base to accommodate the pressurized gas container (12) and a box-shaped upper section, the attachment section of the gas bag (50) is provided with an attachment frame (40) and the attachment frame (40) is inserted in the upper section of the housing (10).
Abstract:
A vehicle occupant safety apparatus (10) for mounting on a portion of a vehicle (12) includes an inflatable vehicle occupant protection device (40). An inflator (30) is actuatable to supply inflation fluid to inflate the inflatable device (40). A cover (70) has a closed condition when the inflatable device (40) is in the deflated condition. The cover (70) is movable from the closed condition to an open condition upon inflation of the inflatable device (40). A wrap (100) is disposed within the cover (70) for maintaining the inflatable device (40) in the deflated condition prior to actuation of the inflator (30). The wrap (100) includes a portion (110) operable to actuate an electrically actuatable device of the vehicle, such as a vehicle horn (102).
Abstract:
A vehicle occupant safety device using: an air bag module (22) including: a housing (24) having a plurality of walls (26a,b) defining a cavity (32) and an open end (30); an air bag (50) received within the cavity, and within the open end in a folded configuration and when inflated by inflation gas expands through the open end to an inflated configuration sufficient to protect the occupant; an inflator (40) operatively received with the housing (24) for providing inflation gas to inflate the air bag; and an external tether (70) enveloping the air bag, including at least one open sided breakable band for initially retarding the forward motion of the inflating air bag toward the occupant and for permitting the inflating air bag to inflate laterally or sideways while its forward motion is retarded and thereafter after the band is fully opened, to permit the air bag to inflate forwardly without retardation.
Abstract:
A gas bag restraint module is provided which comprises a housing provided with a generally hollow accomodation part and with two axially extending attachment strips extending outwards from the accomodation part. A bottle-shaped pressurized gas container is axially inserted into the accomodation part, the gas container providing a volume of pressurized gas after actuation. The gas bag restraint module further comprises a folded gas bag provided with an attachment section surrounding an inflation aperture. The attachment section is connected to the housing by means of an attachment frame which is accomodated between the attachment strips and which comprises at least one through passage.
Abstract:
An airbag cushion assembly including a horn switch unit secured to an airbag cushion with a cushion strap, with the cushion strap and horn switch unit cooperating to retain the airbag cushion in a deflated, folded position prior to mounting the airbag cushion assembly within an airbag module and prior to inflation of the airbag cushion. The horn switch unit defines a first elongated slot, a second elongated slot and a weakened portion rupturable upon a force created by inflation of the airbag cushion to break the horn switch unit between a first and a second elongated slots defined by the horn switch unit. The horn switch unit is positioned on the folded airbag cushion opposite the collar, with a first elongated tether of the cushion strap extending through the first slot of the horn switch unit to a distal end secured to the collar of the airbag cushion, and a second elongated tether extending through the second slot of the horn switch unit to a distal end secured to the collar of the airbag cushion.
Abstract:
In a steering wheel with an air bag device, a horn pad is provided above the air bag device. The air bag device is arranged above a boss plate provided at the center of the steering wheel. Further, a horn switch mechanism operated by depressing the horn pad is provided. In the steering wheel, the horn pad is integral with a core covering portion of a steering wheel body, and a depressing plate is provided immediately below the horn pad. The air bag device is fixedly secured to the boss plate. The depressing plate is preferably substantially rigid, and is so shaped as to straddle the air bag. Resilient members resist the depression of the depressing plate, and pairs of contacts of the horn switch mechanism are provided between the depressing plate and the boss plate to actuate the horn.
Abstract:
An inflatable restraint system assembly and method of operation are provided wherein a compliance chamber pressure vessel formed about the gas exit area of an inflator appropriately and desirably moderates the inflation gas output from the inflator into an associated inflatable device such as inflatable vehicle occupant restraint. The invention has particular utility for use in conjunction with high mass flow rate inflators.
Abstract:
A side impact airbag module assembly adapted to mount on the exterior of the side of a seat back of an automobile seat back having an access opening and receiving means within a internal structural member. The side impact airbag module assembly includes an airbag module frame having a mounting flange adapted to extend through the access opening in the seat cover and having thereon self fasteners that secure the flange in the receiving means of the internal structural member of the seat. An airbag cushion and inflator assembly is secured to the frame, and an airbag module cover is also secured to the airbag module frame to conceal and protect the airbag cushion and inflator assembly and the airbag module frame. The airbag module is provided in one variation with depth limiters that prevent the mounting flange from being inserted too far into the receiving means, and clamp supports which further secure the mounting flange to the internal structural member. In another variation, the airbag module has two spaced apart mounting flanges.
Abstract:
A method of folding an airbag is provided for limiting allowable travel of the first portion of the airbag face panel as the airbag is deployed and for causing complete filling of the airbag prior to engagement with a vehicle occupant. The airbag includes a first end adapted to envelop an inflator. The airbag is laid substantially flat, with the first portion of the airbag face panel closely adjacent the first end. The remainder of the airbag is subsequently collapsed over the first portion while the first portion remains closely adjacent the first end.
Abstract:
An airbag restraint trait forming part of an airbag restraint system mounted on an automotive vehicle. The airbag restraint unit comprises a storage container having an upper section defining a gas ejection opening. A gas generator is disposed inside the storage container. An airbag is fastened to the upper section of the storage container so that gas from the gas generator flows through the gas ejection opening into the airbag when the gas generator is operated. Additionally, a support sheet is disposed between the gas generator and the airbag to support the airbag in a folded state. The support sheet is fastened at its end sections to the storage container and adapted to break under the action of high temperature and pressure gas from the gas generator.
