Abstract

Abstract A restraint (10) comprises an inflatable curtain (14) and a deployment member (16,38). The deployment member can he an inflatable tube within a braided tube (16) or an elastic member (38). The deployment member is attached to the inflatable curtain (14) and on receipt of a signal the member (16,38) deploys the curtain into an occupant protection position in the event of a crash. The restraint is particularly intended for location on one side of a vehicle to provide protection against side impacts.

Independent Claim 24 words
An inflatable restraint for a vehicle occupant comprising an inflatable curtain and a deployment member for moving the curtain into an occupant protection position.
Claim 2
Dependent Claim 19 words
An inflatable restraint according to claim 1 in which a source of gas is provided for inflating the curtain.
Claim 3
Dependent Claim 16 words
An inflatable restraint according to claim 1 or 2 in which the deployment member is elongate.
Claim 4
Dependent Claim 23 words
An inflatable restraint according to claim 3 in which the deployment member contracts longitudinally to move the curtain into said occupant protection position.
Claim 5
Dependent Claim 21 words

Claim 7
Dependent Claim 57 words
An inflatable restraint according to claim 6 in which the deployment member comprises an outer tube of braided material enclosing an inner gas impermeable tube connected, in use, to inflating means whereby inflation of the inner tube increases the diameter of the tube and causes the outer tube to contract longitudinally so as to deploy the curtain.
Claim 8
Dependent Claim 20 words
An inflatable restraint according to any of claims 1 to 5 in which the deployment member is a resilient member.
Claim 9
Dependent Claim 40 words
An inflatable restraint according to claim 8 in which the resilient member is held in an extended state under tension when the curtain is in an un-deployed state and the deployment member is released from tension to deploy the curtain.
Claim 10
Dependent Claim 22 words
An inflatable restraint according to claim 9 in which the resilient deployment member is held in tension by a solenoid operated latch.
Claim 11
Dependent Claim 27 words

Claim 12
Dependent Claim 28 words
An inflatable restraint according to claim 10 in which the solenoid is operable on receipt of a signal, said signal also initiating inflating means for inflating the curtain.
Claim 13
Dependent Claim 17 words
An inflatable restraint according to any preceding claim in which a plurality of deployment members is provided.
Claim 14
Dependent Claim 29 words
