Abstract
Abstract A respirator for emergency oxygen supply for passengers in aircraft, with a mounting container (1), which can be closed with a lid (2), is fastened above the row of seats, and accommodates at least one breathing mask and an exothermic chemical oxygen generator (3) connected to the breathing mask in a holder (4, 5). The pivotability of the lid of the mounting container is improved by rigidly arranging the holder on the mounting container (1) such that it permits the oxygen generator (3) to change its place by pivoting in the case of use.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
99 words
Respirator for emergency oxygen supply for passengers in aircraft, comprising: a mounting container; a lid for closing the mounting container; a breathing mask positionable within the mounting container; an oxygen generator positioned within said mounting container, said oxygen generator being connected to said breathing mask; holding means rigidly connected to said mounting container for permitting a position of said oxygen generator to change by pivoting between a readiness position and a use position, a distance between said oxygen generator and an inner wall surface of said mounting container being greater in said use position than in said readiness position.
Claim 2
Dependent Claim
99 words
Respirator for emergency oxygen supply for passengers in aircraft, comprising: a mounting container; a lid for closing the mounting container; a breathing mask positionable within the mounting container; an oxygen generator positioned within said mounting container, said oxygen generator being connected to said breathing mask; holding means rigidly connected to said mounting container for permitting a position of said oxygen generator to change by pivoting between a readiness position and a use position, a distance between said oxygen generator and an inner wall surface of said mounting container being greater in said use position than in said readiness position.
Claim 3
Dependent Claim
42 words
A respirator according to claim 1, wherein: said oxygen generator includes an activating device coupled with said holding means of said oxygen generator, said oxygen generator moving from said readiness position to said use position only upon activation by said activating device.
Claim 4
Dependent Claim
19 words
A respirator according to claim 2 wherein: said holding means includes a pivoting holder for mounting said oxygen generator.
Claim 5
Dependent Claim
16 words
A respirator according to claim 3, wherein: said pivoting holding includes a hinge and spring mechanism.
Claim 6
Dependent Claim
25 words
A respirator according to claim 1 further comprising: fixed stop means for limiting a range of movement of said oxygen generator in said use position.
Claim 7
Dependent Claim
20 words
A respirator according to claim 5, further comprising: locking connection means for locking said oxygen generator in said use position.
Claim 8
Dependent Claim
88 words
A respirator according to claim 3, wherein: said activating device includes a spring-pretension striking pin, said oxygen generator including two jointing sleeves wherein said spring-pretension striking pin is positioned in one of said two jointing sleeves, a locking pin being provided engaging said striking pin wherein upon removal of said locking pin, said striking pin is released for activation of said oxygen generator, said pivoting holder is released whereby said oxygen generator will pivot out of said readiness position into said use position under the force of gravity.
Claim 9
Dependent Claim
19 words
A respirator according to claim 7, including a pretensioned spring to assist in pivotal movement of said oxygen generator.
Claim 10
Dependent Claim
16 words
A respirator according to claim 1, further comprising: a cartridge shaped housing accommodating said oxygen generator.
Claim 11
Dependent Claim
42 words
A respirator according to claim 1, wherein: said holding means is formed as a hinged holder attached to said oxygen generator for pivoting said oxygen generator around a fixed axis on said mounting container, between said readiness position and said use position.
Claim 12
Dependent Claim
41 words
A respirator according to claim 10, further comprising: said hinged holder, clamping straps, and cartridge mounts including cartridge holders attached to said oxygen generator by said clamping straps and mounted rotatably around axes in said cartridge mounts on said mounting container.
Claim 13
Dependent Claim
21 words
A respirator according to claim 11, wherein: said clamping straps include projections for locking said oxygen generator in said readiness position.
Claim 14
Dependent Claim
44 words
A respirator according to claim 10, further comprising: a strap compiling said oxygen generator with said hinged holder, said strap releasing said hinged holder during activation of said oxygen generator whereby said oxygen generator is moved from said readiness position into said use position.
Claim 15
Dependent Claim
34 words
A respirator according to claim 13, further comprising: strap mounts for mounting said strap axially rotatably and has strap right-angle bends and projectors engaged by said strap right-angle bends to lock said oxygen generator.
Claim 16
Dependent Claim
23 words
A respirator according to claim 10, wherein: said hinged holder includes a locking device limiting a range of movement in said use position.
Claim 17
Dependent Claim
32 words
A respirator according to claim 15, wherein: said locking device includes flattened areas on an axial shaft portion of said hinged holder and slotted holes of corresponding shape in said cartridge holders.
