Abstract

To enable the easy adjustment of the height of the upper end of a shoulder belt of webbing utilizing a shoulder guard provided to a strut provided on both right and left sides of a seat. An air belt system is provided with webbing in which a lap belt that cannot be inflated and a shoulder belt that can be inflated are connected to each other. A retractor is provided to one side of a seat for winding the end of the lap belt. A tongue is supported in an intermediate part of the webbing so that the tongue can slide relative thereto. A buckle is provided on the other side of the seat for connecting the tongue so that the tongue can be detached. An inflator is connected to the end of the shoulder belt for supplying high pressure gas to the shoulder belt. Right and left shoulder guards are respectively provided to the struts provided on both right and left sides of the seat so that the upper and lower positions can be adjusted. The upper end of the shoulder belt and the inflator are attached to right or left shoulder guards.

Claims

1. A vehicular passive safety device comprising:

a lap belt;

a shoulder belt capable of being inflated;

a retractor provided on one side of a seat for winding an end of the lap belt;

a tongue supported on an intermediate portion of the lap belt wherein the tongue can slide relative thereto;

a buckle provided on the other side of the seat for detachable connecting the tongue relative thereto; and

an inflator operatively connected to said shoulder belt for restraining an occupant by inflating the shoulder belt with high pressure gas from the inflator when a vehicle collides;

an end of said shoulder belt being disposed adjacent to the inflator is attached to a first strut provided on a side of the seat wherein the upper and lower positions can be adjusted for protecting the shoulders of an occupant.

2. The vehicular passive safety device according to claim 1, and further including a first shoulder guard operatively connected to said first strut for protecting the shoulder of an occupant.

3. The vehicular passive safety device according to claim 1, wherein said shoulder belt includes a bag operatively connected to said inflator, said bag being inflated by said inflator upon actuation.

4. The vehicular passive safety device according to claim 1, and further including a second strut, said first strut being disposed on one side of an occupant and the second strut being disposed on an opposite side of an occupant, said shoulder belt being attached to a first shoulder guard and a second shoulder guard being operatively connected to said second strut.

5. The vehicular passive safety device according to claim 4, wherein said first shoulder guard operatively connected to said first strut includes said inflator operatively mounted therein, said end of said shoulder belt being in communication with said inflator being mounted on said second shoulder guard.

6. The vehicular passive safety device according to claim 4, wherein said first strut includes a plurality of apertures space along a length thereof for adjustably mounting said first shoulder guard relative thereto.

7. The vehicular passive safety device according to claim 4, wherein said second strut includes a plurality of apertures space along a length thereof for adjustably mounting said second shoulder guard relative thereto.

8. The vehicular passive safety device according to claim 4, wherein said first shoulder guard includes a groove for mounting relative to said first strut, said first strut including a plurality of slots disposed along a length thereof and further including a connector secured to said first shoulder guard and adapted to be selectively mounted relative to one of said plurality of slots for adjusting the height of said first shoulder guard.

9. A passive safety device adapted for use in a vehicle comprising:

a shoulder belt capable of being inflated;

an inflator operatively connected to said shoulder belt for inflating the shoulder belt with high pressure gas from the inflator upon the occurrence of a predetermined condition; and

an end of said shoulder belt being disposed adjacent to the inflator and being attached to a first strut wherein an upper and lower position is adjustable for adjusting a height of said end of said shoulder belt.

10. The passive safety device according to claim 9, and further including a first shoulder guard operatively connected to said first strut, said end of said shoulder belt being mounted on said first shoulder guard.

11. The passive safety device according to claim 9, wherein said shoulder belt includes a bag operatively connected to said inflator, said bag being inflated by said inflator upon actuation.

12. The passive safety device according to claim 9, and further including a second strut, said first strut being disposed on one side and the second strut being disposed on an opposite side, said shoulder belt being attached to a first shoulder guard and a second shoulder guard being operatively connected to said second strut.

13. The passive safety device according to claim 12, wherein said first shoulder guard operatively connected to said first strut includes said inflator operatively mounted therein, said end of said shoulder belt in communication with said inflator being mounted on said second shoulder guard.

14. The vehicular passive safety device according to claim 12, wherein said first strut includes a plurality of apertures space along a length thereof for adjustably mounting said first shoulder guard relative thereto.

15. The vehicular passive safety device according to claim 12, wherein said second strut includes a plurality of apertures space along a length thereof for adjustably mounting said second shoulder guard relative thereto.

16. The vehicular passive safety device according to claim 12, wherein said first shoulder guard includes a groove for mounting relative to said first strut, said first strut including a plurality of slots disposed along a length thereof and further including a connector secured to said first shoulder guard and adapted to be selectively mounted relative to one of said plurality of slots for adjusting the height of said first shoulder guard.
