Abstract

Abstract An occupant restraint system for a vehicle body includes a manifold provided by an elongated shallow trough having flanged walls which define an opening in general alignment with an elongated opening in the upper portion of the instrument panel adjacent the windshield. An oval-shape slotted diffuser seats on the base wall of the trough and is bolted through the trough to brackets on the cowl structure of the body to mount the trough and diffuser in place. One end of the diffuser is closed and the other end communicates with a source of pressure fluid such as a pressure vessel or gas generator. An occupant restraint cushion is of T cross section and includes an elongated tapered umbilical portion having one open side thereof receiving the opening of the trough and secured to the flanged walls thereof. An elongated pillow portion of the cushion communicates with the other open side of the umbilical portion and extends transversely of the umbilical portion. The pillow portion extends peripherally beyond the umbilical portion on all sides. When the cushion is in stored position, it is rolled upon itself and received within the trough. A cover for the opening in the instrument panel has flanges releasably clamped between the flanged walls of the trough and the upper portion of the instrument panel. One or more valves in the walls of the trough close openings which communicate with the interior of the vehicle or with ambient atmosphere. The trough brackets, additional brackets from the cowl structure, and tie bars support a lower knee panel which extends transversely of the vehicle underneath the instrument panel. The knee panel includes a perforated steel base covered with semi-rigid resilient material and an outer decorative covering. When the source of pressure fluid is communicated with the diffuser, the diffuser expands from oval shape toward a round shape and relocates the slots during such change in shape. The pressure fluid flows from the diffuser into the trough and then into the cushion to inflate the cushion. The umbilical portion is projected rearwardly and generally upwardly of the body through the opening in the upper portion of the instrument panel and is located between the windshield and such upper portion. The pillow portion is erected generally vertically of the body rearwardly of the frontal portion of the instrument panel and of the steering wheel. The tapered umbilical portion locates the pillow portion angularly of the frontal portion of the instrument panel so that its right-hand side is located adjacent the right-hand side of the frontal portion of the instrument panel and its left-hand side clears the steering wheel.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 134 words
The combination comprising, a vehicle body having an instrument panel including a generally transversely extending upper portion having a forward periphery of generally U shape, a generally T-shaped inflatable occupant restraint cushion including an elongate umbilical portion and a pillow portion located laterally of the umbilical portion, and means mounting the umbilical portion on the upper portion of the instrument panel in chordal relationship to the bight portion of the periphery thereof, the umbilical portion having a lesser extent transversely of the body than the upper portion of the instrument panel and extending rearwardly thereof, the pillow portion being located rearwardly of the upper portion of the instrument panel generally vertically of the body and having an extent transversely of the body generally equal to that of the upper portion of the instrument panel.
Claim 2
Dependent Claim 134 words
The combination comprising, a vehicle body having an instrument panel including a generally transversely extending upper portion having a forward periphery of generally U shape, a generally T-shaped inflatable occupant restraint cushion including an elongate umbilical portion and a pillow portion located laterally of the umbilical portion, and means mounting the umbilical portion on the upper portion of the instrument panel in chordal relationship to the bight portion of the periphery thereof, the umbilical portion having a lesser extent transversely of the body than the upper portion of the instrument panel and extending rearwardly thereof, the pillow portion being located rearwardly of the upper portion of the instrument panel generally vertically of the body and having an extent transversely of the body generally equal to that of the upper portion of the instrument panel.
Claim 3
Dependent Claim 106 words
The combination comprising, a vehicle body having an instrument panel including a rearward portion and an upper portion, a generally T-shaped inflatable occupant restraint cushion including an umbilical portion and a pillow portion, means mounting the forward terminus of the umbilical portion on the upper portion of the instrument panel, the umbilical portion extending rearwardly of the upper portion of the instrument panel and having the rearward terminus thereof located angularly to the rearward portion of the instrument panel and secured to the pillow portion, the pillow portion being thus located angularly of the rearward portion of the instrument panel and generally vertically of the body.
Claim 4
Dependent Claim 106 words
The combination comprising, a vehicle body having an instrument panel including a rearward portion and an upper portion, a generally T-shaped inflatable occupant restraint cushion including an umbilical portion and a pillow portion, means mounting the forward terminus of the umbilical portion on the upper portion of the instrument panel, the umbilical portion extending rearwardly of the upper portion of the instrument panel and having the rearward terminus thereof located angularly to the rearward portion of the instrument panel and secured to the pillow portion, the pillow portion being thus located angularly of the rearward portion of the instrument panel and generally vertically of the body.
Claim 5
Dependent Claim 125 words
The combination comprising, a vehicle body having an instrument panel including an upper portion, a rearward portion and a steering wheel located adjacent the rearward portion to one side of the body, a generally T-shaped inflatable occupant restraint cushion including an umbilical portion and a pillow portion, means mounting the forward terminus of the umbilical portion on the upper portion of the instrument panel, the umbilical portion extending rearwardly of the upper portion of the instrument panel and having the rearward terminus thereof located angularly to the rearward portion of the instrument panel and secured to the pillow portion, the pillow portion being thus located angularly of the rearward portion of the instrument panel and rearwardly of the steering wheel generally vertically of the body.
