Claims
1. A material cover (27) for a vehicle seat (22), the seat having a seat back (26) having a front surface (28), a rear surface (32) and a side surface (30),
the material cover (27) which when in place, covers the front (28), rear (32) and side (30) of the seat back, wherein the cover includes a side panel (30' ) ;
first means (50,50') for effectively decreasing the elongation of the side panel (30' ) to localize stress in the side panel (30') to encourage the side panel to tear along a generally predetermined line in response to the action of an inflating air bag (46) .

2. The device as defined m Claim 1 wherein the first means includes a flexible, multi-sided
reinforcement panel (50) secured to the inside of the side panel (30').

3. The device as defined in Claim 1 wherein the first means includes a plurality of thin,
lightweight, flexible pieces of material (70a-c) joined together as a panel having an elongation less than the elongation of the side panel of the seat cover.

4. The device as defined in Claim 1 wherein the first means comprises a panel (50") having a narrowed front edge (52a).

5. The device as defined in Claim 1 wherein the panel is coextensive with the side panel (32' ) .

6. The device as defined in Claim 1 wherein the side panel (30') is a low elongation material.

7. A vehicle seat (22) including a seat back (26) having a front surface (28), a rear surface (32) and a side surface (30) ,
the material cover (27) which when m place, covers the front (28) , rear (32) and side (30) of the seat back, wherein the cover includes a side panel (30');
first means (50,50') for effectively decreasing the elongation of the side panel (30' ) to localize stress in the side panel (30') to encourage the side panel to tear along a generally predetermined line in response to an inflating air bag (46) ;
the air bag located proximate a side of the seat back and
and mflator for providing inflation gas to the air bag.

8. The device as defined in Claim 7 wherein the first means includes a flexible, multi-sided
reinforcement panel (50) secured to the inside of the side panel (30' ) .

9. The device as defmed in Claim 7 wherein the first means includes a plurality of thm,
lightweight, flexible pieces of material (70a-c) joined together as a panel having an elongation less than the elongation of the side panel of the seat cover.

10. The device as defined in Claim 7 wherein the first means comprises a panel (50") with a narrowed front edge (52a).

11. The device as defined m Claim 7 wherein the panel is coextensive with the side panel (32' ) .

12. The device as defined in Claim 1 wherein the side panel (30') is a low elongation material.

13. The device as defined in Claim 1 wherein the air bag impinges on the first means with a forward component of force and a perpendicular component to open a forward side of the first means.

14. The device as defined m Claim 7 wherein the air bag impinges on the first means with a forward component of force and a perpendicular component to open a forward side of the first means.

15. The device as defined m Claim 1 wherein the elongation of the first means is less than 16%.

16. The device as defined in Claim 1 wherein the elongation of the first means is less than or equal to the elongation of one of a nylon film, a
polypropylene sheet, a seat belt webbing.
