An automotive glove box assembly. The glove box assembly includes a storage bin and a door disposed in hinging relation to the storage bin. The door includes an expansible body having a face portion facing towards a vehicle occupant and a back portion in opposing relation to the face portion. The expansible body is operatively connected to at least one gas emitting unit such that upon discharge of gas from the gas emitting unit, the expansible body is pressurized and the face portion is projected outwardly to an extended position so as to intercept lower extremities of the occupant.

Passenger side active knee bolster

An inflatable knee bolster for a vehicle occupant is mounted in opposing relation to the knees of a vehicle occupant. The bolster is an expansible chamber of multipiece construction having a face portion and a separate three dimensional expansible body portion. The face portion and body portion are joined about their peripheries to define and substantially enclose the chamber. The expansible body portion is formed from injection molded polymeric material and has one or more integrally molded at least partially collapsible pleated profile elements disposed along the sides and across the top of the body portion in raised and lowered profile with respect to the face portion. Deformable mounting brackets extend outwardly from the body portion for attachment to the vehicle. The materials forming the face and body portions are of either similar or dissimilar chemical and physical character. Actuation of an inflator in fluid communication with the bolster pressurizes the expansible body causing at least a portion of the pleated profile elements to collapsibly deform such that the volume of the enclosed chamber is expanded and the face portion is thrust outwardly to an extended position.

An inflatable knee bolster for a vehicle occupant is mounted to the bottom of the vehicle's instrument panel, having an outer wall that is projected outwardly from a stored position to an extended position adjacent the occupant's knees by inflation of an expansible chamber by an inflator, characterized by. The bolster is an expansible chamber comprising a unitary hollow blow molded polypropylene body that has an outer wall and an inner wall which are interconnected at their bottoms by a bottom wall and at their tops and sides by U-shaped normally folded accordion pleats. These pleats extend from the bottom side corners of the body up the sides and across the top of the body. A pair of spaced attachment tabs extend from the bottom wall for attachment to vehicle structure, and a pair of spaced frangible tabs extending from the top of the outer wall for attachment to vehicle structure to maintain the outer wall in stored position. An inflator is mounted on the hollow body in fluid communication with the interior of the body and, when activated, pressurizes the expansible body to unfold the accordion pleats to expand the body. This breaks the frangible tab and projects the front wall outwardly to extended position adjacent the occupant's knees. A pair of vent holes formed in the inner wall enable controlled depressurization of the bolster.

An air bag module includes an air bag and an inflator for generating gas to inflate the air bag. The module further includes a bias apparatus including first and second bias flaps being separate and independent from each other. The bias flaps cooperatively define an overlapped portion located atop the air bag prior to inflation such that the inflating air bag is biased when the overlapped portion is restricted and the inflating air bag is unrestrained when the overlapped portion is unrestricted. Preferably, the first and second flaps each have a fixed edge attached to the vehicle and each have a free edge opposite the fixed edge. The free edges of the first and second bias flaps overlap each other to define the overlapped portion.

A supplemental inflatable restraint is provided including an air bag housing positioned in an instrument panel lower surface with an open end extending toward the seated occupant, the open end having a top and a bottom; and an air bag which has a lower lobe for contact with lower extremities of a seated occupant and an upper lobe for contact with the torso of a seated occupant. The upper and lower lobes are separated by a first tether extending from an area generally adjacent to the top of the housing projecting generally toward the seated occupant. The air bag has a pressure restrictor creating a pressure differential between the upper and lower lobes. The upper lobe is subdivided by a second tether from an area adjacent to the top of the housing to an end of the upper lobe generally opposite the lower lobe.

Vehicle body/supplemental inflation restraint arrangement

A particulate impingement device is carried by the air bag and has an impingement surface overlying the vent hole at a spaced relationship away from the vent hole so that the inflation gas exiting the air bag through the vent hole impinges on the impingement surface to deposit particulate by-products within the inflation gas upon the impingement surface.

A restraint cushion is comprised of first and second fabric panels. Each of the two fabric panels is folded and interleaved with the other to form the restraint cushion. A single continuous seam interconnects the mating edges of the two panels. The restraint cushion has a generally cubic shape defined by top, bottom, forward, rearward, left, and right side. Each of the two fabric panels is a generally elongate continuous strip folded to a U-shape and interleaved with the other to form the cubic shape of the restraint cushion. The restraint cushion minimizes the number of panels used in forming the restraint cushion and minimizes the number of seams sewn to interconnect the panels so that the assembly costs of the restraint cushion are reduced.
