A safety device for a vehicle seat

摘要

A safety device for a vehicle seat comprises a lap belt 2, which may be part of a three point harness (see figure 2) or may be solely a lap belt as shown, having a folded inflatable air bag 7 secured to one end thereof. On inflation the air bag will expand towards the buckle end 5 of the lap belt beyond the location of the air bag when folded (see figures 20 to 22). The length and location of the folded air bag is such that the folded air bag will not engage means located at the other end of the lap belt for releasably connecting to the buckle 5 even when the lap belt is buckled and extends substantially tightly across the occupant less seat. The air bag may be folded in a particularly defined manner (see figures 4 to 16).
