Vehicular passive safety device
First Claim
1. A vehicular passive safety device for inflating a portion of a webbing diagonally arranged to be in front (B) of an occupant so as to bind the occupant on a seat with a high pressure gas generated by an inflator when a vehicle collides comprising:
- an upper portion of the webbing to be inflated is located in a position wherein a side of a head (H) and a neck (N) of an occupant can be protected, wherein the inflator is mounted on a cross member adjacent to the upper portion of the webbing to be inflated, the cross member being a tubular member connecting to struts on both sides of the seat.

Abstract
To enable effectively binding the front, the head and the neck of an occupant in a vehicular passive safety device that binds the occupant by inflating the webbing. As an upper portion of an inflated portion of webbing of an air belt system is located in a position in which each side of the head H and the neck N of an occupant can be protected, it is needless to say that the front B of the occupant can be softly bound with the inflated portion in a head-on collision. The head H and the neck N of the occupant are softly bound in a side impact and the air belt system can also function as a side air bag system and an air curtain system. In addition, as the thickness of the portion to be inflated becomes thinner downwardly from the upper portion, the required capacity of an inflator can be reduced by reducing the volume of a lower portion of the inflated portion in which required binding force can be easily acquired even if the lower portion is thinned.

9. A vehicular passive safety device comprising:
-
a webbing adapted for restraining a passenger relative to a vehicle, said webbing including a portion adapted to be selectively inflated with a gas generated by an inflator based on a predetermined condition; and
an upper portion of the webbing to be inflated being located adjacent to a side of a head (H) and a neck (N) of an occupant for protecting a head (H) and a neck (N) upon the occurrence of said predetermined condition, wherein the inflator is mounted on a forward side of a cross member and is rigidly connected by a high pressure gas pipe to the upper portion of the webbing to be inflated, the upper portion of the webbing being inward of the inflator. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
