Abstract
Abstract The present invention relates to a life-jacket assembly primarily intended for aircraft passengers, including a buoyant body (7) furnishing at least the principal part of the buoyancy, and straps or the like adapted to retain the life-jacket assembly in position on persons in emergency situations, said buoyant body (7) being utilized as upholstery in a chair or the like. The novel feature is that the life-jacket includes an elongated, generally flat buoyant body (7) substantially made of buoyancy material, that the life-jacket is entirely contained in an upwardly open compartment in the back-rest of a chair where the buoyant body (7) forms at least part of the upholstery, that an end surface of the life-jacket is provided with a pull handle (6) which is accessible at the top end of the back-rest, and that the generally flat body (7) has, at some distance from that end which is provided with the pull handle, an opening (8) through which the user has to pass his head.

Claim 1
Independent Claim
156 words
Life-jacket assembly primarily intended for aircraft passengers, including a buoyant body (7) furnishing at least the principal part of the buoyancy, and straps or the like adapted to retain the life-jacket assembly in position on persons in emergency situations, said buoyant body (7) being utilized as upholstery in a chair or the like, characterized in that the life-jacket includes an elongated, generally flat buoyant body (7) substantially made of buoyancy material, that the life-jacket is entirely contained in an upwardly open'compartment in the back-rest of a chair where the buoyant body (7) forms at least part of the upholstery, that an end surface of the life-jacket is provided with a pull handle (6) which is accessible at the top end of the back-rest, and that the generally flat body (7), has at some distance from that end which is provided with the pull handle, an opening (8) through which the user has to pass his head.
Claim 2
Dependent Claim
156 words
Life-jacket assembly primarily intended for aircraft passengers, including a buoyant body (7) furnishing at least the principal part of the buoyancy, and straps or the like adapted to retain the life-jacket assembly in position on persons in emergency situations, said buoyant body (7) being utilized as upholstery in a chair or the like, characterized in that the life-jacket includes an elongated, generally flat buoyant body (7) substantially made of buoyancy material, that the life-jacket is entirely contained in an upwardly open'compartment in the back-rest of a chair where the buoyant body (7) forms at least part of the upholstery, that an end surface of the life-jacket is provided with a pull handle (6) which is accessible at the top end of the back-rest, and that the generally flat body (7), has at some distance from that end which is provided with the pull handle, an opening (8) through which the user has to pass his head.
Claim 3
Dependent Claim
69 words
Life-jacket assembly as claimed in claim 1, characterized in that a displaceable material portion (9) of principally the same material as the rest of the buoyant body fills up, in the stored position of the life-jacket, the opening (8) situated at a distance from the ends of the buoyant body but in the position of use of the life-jacket said material portion (9) is removed from said opening (8).
Claim 4
Dependent Claim
71 words
Life-jacket assembly as claimed in claim 1, characterized in that a back piece (10) made of flexible fabric material adjacent the opening (8) of the buoyant body (7) is attached to said body which preferably is wrapped with a covering, and that tightenable waist straps (11) fastened to the forward end of the buoyant body which is provided with the handle (6) extend from the free end of said back piece.
Claim 5
Dependent Claim
72 words
Life-jacket assembly as claimed in claim 2, characterized in that the displaceable material portion (9) is retained in the position where it fills up the opening (8), against the action of an elastic means (13) tending to remove said portion from the opening of the buoyant body (7) by a detachable fastening means adapted to be rendered inactive as the life-jacket is pulled out from the compartment in the chair back-rest (3).
Claim 6
Dependent Claim
65 words
Life-jacket assembly as claimed in claim 4, characterized in that the displaceable material portion (9) filling up the opening (8) is pivotally attached to the rest of the buoyant body and adapted, as the fastening means is rendered inactive, to be swung into abutment against the surface of the buoyant body adjacent the opening in order to provide a concentration of buoyancy on said surface.
Claim 7
Dependent Claim
135 words
Life-jacket assembly as claimed in claim 2, characterized in that the elongated buoyant body (7') of the life-jacket has at one end a thickened portion furnishing the principal part of the buoyancy, that the opening (8) situated at a distance from said portion and the opposite end of the buoyant body is formed of a generally C-shaped slit (16) defining a withdrawable tongue (20), that between the free edge of said tongue and the buoyant body there are arranged stay bands (22) adapted to admit limited outward turning or bending of the tongue which in bent- out position serves as a neck rest in the life-jacket, and that the back piece and waist straps (10', 11') for fastening the life-jacket to the distressed person are attached to the respective end portions of the material piece.
Claim 8
Dependent Claim
42 words
Life-jacket assembly as claimed in claim 2, characterized in that the buoyant body of the life-jacket, which at least for its major part consists of buoyancy material, is adapted to be completed with cavities which can be filled with air or gas.
