Knee Airbag with Passive Venting for Out of Position Occupant Protection

Номер: US20130020788A1
Автор: Brian Robert Spahn, Ian Brewster Hall, Manoharprasad K. Rao
Принадлежит: FORD GLOBAL TECHNOLOGIES LLC

A knee airbag installed in a lower portion of an instrument panel has a deployed condition wherein it extends rearward and upward. The airbag has a left lobe, a right lobe, and a central portion between and joined to the left and right lobes. A vent is formed in the reaction surface of each of the lobes to allow inflation gasses to escape from the airbag when, during a crash event, an occupant force applied forwardly against the lobes is below a threshold level. When the occupant force reaches or exceeds the threshold level, the vents are urged against the instrument panel to substantially block the escape of inflation gasses. The threshold level is selected such that a child-sized occupant standing forward of a desired passenger seating position exerts less than the threshold level.

An airbag of a side airbag apparatus includes an upstream inflation portion, which inflates by inflation gas, and deploys frontward at a side of a vehicle seat. An opening is provided at a wall portion of the upstream inflation portion. A pressure regulator valve closes before an occupant is restrained by the upstream inflation portion, thereby restricting the inflation gas in the upstream inflation portion from flowing through the opening. Upon the occupant restraint, the pressure regulator valve cancels the restriction in response to a change in a tensed state of the dividing portion by an external force applied due to the restraint. A tear seam that connects valve body portions of the pressure regulator valve delays the opening time of the pressure regulator valve upon the occupant restraint by the upstream inflation portion relative to the opening time set only by the pressure regulator valve. 121-.

A flow deflector between the opening and an exterior vent combines with the wall to define a channel therebetween. The channel directs inflation gasses exiting the opening into an upper end of the airbag, after which the gasses must flow around an upper end of the deflector (adjacent an outlet end of the channel) before reaching the exterior vent. The resulting S-shaped flow path serves to maintain the airbag in the inflated state for a longer time and urges an outboard arm of an occupant in a forward an upward direction to reduce the likelihood that that arm may be trapped between the inflating airbag and the occupant's thorax. 120-.
