Abstract

Abstract A vehicle occupant shoulder restraint (51c) is located on a vehicle door and is inflatable from a stored condition on the door to an inflated condition between the door and the shoulder area of an occupant. When inflated, the occupant shoulder restraint (51c) engages the shoulder of the occupant. A vehicle occupant upper rib restraint (52c,53c) is located on the vehicle door and is inflatable from a stored condition on the door to an inflated condition between the door and the upper rib area of the occupant. When inflated, the shoulder restraint (51c) extends further into the vehicle passenger compartment than the upper rib restraint (52c,53c). When inflated, the occupant rib restraint (52c,53c) engages the upper rib area of the occupant. In another embodiment of the invention a vehicle occupant head restraint (210) is located on the vehicle door and is inflatable from a stored condition on the door to an inflated condition between the door and the head of the occupant. When inflated, the occupant head restraint (210) engages the head of the occupant. The occupant head restraint (210) is inflated into position to restrain the head of the occupant after the occupant shoulder restraint (51c) has been inflated and has restrained the shoulder of the occupant.

Claim 5
Dependent Claim 103 words
An apparatus according to claim 4 wherein (i) said first portion of said occupant shoulder restraint means is located adjacent the shoulder area of the occupant to resist movement of the shoulder area of the occupant when said first portion is inflated and the shoulder area of the occupant engages said first portion, and (ii) said second portion of said occupant upper rib restraint means is located adjacent the upper rib area of the occupant to resist movement of the rib area of the occupant when said second portion is inflated and the upper rib area of the occupant engages said second portion.
Claim 6
Dependent Claim 38 words
An apparatus according to claim 5 wherein each of said first and second portions, when inflated, is tubular in shape and has its longitudinal central axis extending along the forward and rearward directions of travel of the vehicle.
Claim 7
Dependent Claim 28 words
An apparatus according to claim 5 further comprising pad means associated with said first and second portions for acting between said first and second portions and the occupant.
Claim 8
Dependent Claim 48 words
An apparatus according to claim 7 further comprising at least one tether strap interconnecting the vehicle side and said pad means and for limiting movement of said pad means and said first and second portions into the vehicle passenger compartment when said first and second portions are inflated.
Claim 9
Dependent Claim 40 words
An apparatus according to claim 4 wherein each of said first and second portions includes vent valve means for releasing inflation fluid from the chamber of the respective portion to control the pressure in the chamber of the respective portion.
Claim 10
Dependent Claim 60 words
An apparatus according to claim 9 wherein (i) said vent valve means of said first portion opens when the pressure in said first chamber reaches a first predetermined pressure, and (ii) said vent valve means of said second portion opens when the pressure in said second chamber reaches a second predetermined pressure which is lower than said first predetermined pressure.
Claim 11
Dependent Claim 52 words
An apparatus according to claim 5 further comprising vehicle occupant head restraint means located on the vehicle side and inflatable from a stored condition on the vehicle side to an inflated condition between the vehicle side and the head of the occupant and for, when inflated, engaging the head of the occupant.
Claim 12
Dependent Claim 46 words
An apparatus according to claim 11 wherein said occupant head restraint means includes a third inflatable portion defining a third chamber into which inflation fluid from said first chamber of said first portion flows to inflate said third portion after said first portion has been inflated.
Claim 13
Dependent Claim 36 words
An apparatus according to claim 12 wherein said third portion is located adjacent the head of the occupant to protect the head of the occupant when said third portion is inflated from forcibly striking an object.
