Abstract

Abstract A vehicle safety arrangment comprising a seat back support (4a) adapted to be attached to the back of a vehicle seat (50) and a side impact protective air bag module comprising an inflator (1) and a folded inflatable air bag (8). The seat back support (4a) is formed with integrally moulded or extruded flanges forming a housing for the inflator (1) and the air bag (8), and with a gas channle (16) linking the inflator (1) with the air bag (8). The arrangement can be placed outside the seat structure and sill not conflict with occupant comfort. Furthermore since it is independent of the seat structure it can be manufactured separately. The arrangement also comprises fewer component parts with attendant cost and weight savings and making it easier to manufacture. The seat back support (4a) is a plastic module which can be snapped or bolted onto the back of a front seat (50) and is generally used to prevent injury to rear passengers such as from submarining. The present invention provides a seat back support (4a) integrated air bag (8) arrangement with either a plastics extruded or a plastics moulded housing design and provides a side impact system that is compact in design and lightweight, easy to assemble and inexpensive.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 75 words
A vehicle safety arrangement comprising a sat back support (4a, 17) adapted to be attached to the back of a vehicle seat (50) and a side impact protective airbag module comprising an inflator (1) and a folded inflatable airbag (8) characterised in that the seat back support (4a, 17) is formed with integral flanges (7, 18, 19) providing a housing for the inflator, and providing a gas channel (16) linking the inflator with air bag.
Claim 2
Dependent Claim 75 words
A vehicle safety arrangement comprising a sat back support (4a, 17) adapted to be attached to the back of a vehicle seat (50) and a side impact protective airbag module comprising an inflator (1) and a folded inflatable airbag (8) characterised in that the seat back support (4a, 17) is formed with integral flanges (7, 18, 19) providing a housing for the inflator, and providing a gas channel (16) linking the inflator with air bag.
Claim 3
Dependent Claim 27 words
A vehicle safety arrangement according to claim 1, characterised in that the integral flanges (7, 18, 19) are formed by moulding the seat back support (4a, 17).
Claim 4
Dependent Claim 28 words
A vehicle safety arrangement according to claim 1, characterised in that the integral flanges (7, 18, 19) are formed by extrusion of the seat back support (4a, 17).
Claim 5
Dependent Claim 49 words
A vehicle safety arrangement according to claim 1, characterised in that the flanges (7, 18, 19) further provide a housing for the folded airbag (8), and define a fixed direction of inflation opening for the inflating airbag (8), generally in a direction toward the front of the seat (50).
Claim 6
Dependent Claim 76 words
A vehicle safety arrangement according to claim 4, characterised in that integral flanges (7, 18, 19) comprise two side walls, relatively closely spaced and generally parallel to each other and to the side of the seat (50) and extending at least partially at the side of the vehicle seat (50) and wherein at least the outwardly positioned side wall (7) is resilient so as to flex outwardly under pressure exerted by an inflating air bag (8).
Claim 7
Dependent Claim 34 words
A vehicle safety arrangement according to claim 1, characterised in that the flanges (7, 18, 19) form a generally cylindrical, vertically extending chamber in the region of their connection to the seat back support.
Claim 8
Dependent Claim 54 words
A vehicle safety arrangement according to claim 1, characterised in that the seat back support (4a, 17) has snap-fit or bolting means for connection to a vehicle seat in a position on the seat (50) which provides stiffness to the back of the seat to resist a rear occupant sliding under the seat (50).
Claim 9
Dependent Claim 29 words
A vehicle safety arrangement according to claim 1, characterised in that the air bag module has a length shorter than the height of the back of the seat (50).
Claim 10
Dependent Claim 19 words
A vehicle safety arrangement according to claim 1, characterised by an air bag (8) of an elongate arcuate shape.
Claim 11
Dependent Claim 18 words
A vehicle safety arrangement according to claim 1, characterised by an air bag (8) of a sausage shape.
Claim 12
Dependent Claim 33 words
A vehicle safety arrangement according to claim 1, characterised by an air bag (8) of a shape which protects both head and torso of a vehicle occupant in response to a crash situation.
Claim 13
Dependent Claim 42 words
A vehicle safety arrangement according to claim 1, characterised in that the air bag (8) comprises a plurality of mechanical attachment means spaced along its inflation opening and the peripheral edges of the flanges (7, 18, 19) comprise cooperative mechanical attachment means.
Claim 14
Dependent Claim 23 words
A vehicle safety arrangement according to claim 1, characterised in that the air bag module is covered by a vehicle seat cover (3).
Claim 15
Dependent Claim 28 words
A vehicle safety arrangement according to claim 13, characterised in that the folded air bag (8) is contained within a flexible fabric pocket (5) within the housing (25).
Claim 16
Dependent Claim 24 words
A vehicle safety arrangement according to claim 14, characterised in that fabric pocket (5) is attached to a seam of the seat cover (3).
Claim 17
Dependent Claim 32 words
A vehicle safety arrangement according to claim 15, characterised in that the pocket (5) has a seam (6) which is coextensive with a portion of the seam of the seat cover (3).
Claim 18
Dependent Claim 29 words
A vehicle safety arrangement according to claim 15, characterised in that the seam (6) is stitched with a thread having a tear strength of between 100 and 500 Newtons.
Claim 19
Dependent Claim 34 words
A vehicle safety arrangement according to claim 1, characterised in that the air bag module is covered with a dust protector sealing the open edges of the seat back support flanges (7, 18, 19).
