Abstract

A mask stowage container is provided having a door panel coupled to a box via a securement mechanism, the securement mechanism having a striker having a neck and a protrusion, the striker mounted to the door panel, a holder, the holder including a first retainer and a second retainer, the striker configured to be laterally retained between the first retainer and the second retainer.

First claim

What is claimed is:

1. A mask stowage container comprising:
a housing;
a door assembly, the door assembly comprising a first door panel and a second door panel that define a mounting structure configured to retain an oxygen mask;
a first spring-biased hinge joint connecting the first door panel to the housing;
a second spring-biased hinge joint connecting the second door panel to the housing; and
a plurality of securement mechanisms, wherein a first securement mechanism of the plurality of securement mechanisms is coupled to the first door panel and the housing, wherein a second securement mechanism of the plurality of securement mechanisms is coupled to the second door panel and the housing, wherein each of the first securement mechanism and the second securement mechanism comprises a striker and a holder, and wherein the plurality of securement mechanisms prevent an inadvertent opening of the door assembly due to at least one of vibration or acceleration.

2. The mask stowage container of claim 1 ,
wherein the first securement mechanism comprises a first striker and a first holder, wherein the first striker comprises a first neck and a first protrusion, wherein the first striker is mounted to the first door panel; wherein the first holder is mounted to the housing and includes a first first retainer and a first second retainer, the first striker configured to be laterally retained between the first first retainer and the first second retainer, wherein the first first retainer and the first second retainer are coupled via a first U shaped bracket, wherein the second securement mechanism a second striker and a second holder, wherein the second striker comprises a second neck and a second protrusion, wherein the second striker is mounted to the second door panel; wherein the second holder is mounted to the housing and includes a second first retainer and a second second retainer, the second striker configured to be laterally retained between the second first retainer and the second second retainer, and wherein the second first retainer and the second second retainer are coupled via a second U shaped bracket.

3. The mask stowage container of claim 2 , wherein the first first retainer, the first second retainer and the first U shaped bracket are monolithic and wherein the second first retainer, the second second retainer and the second U shaped bracket are monolithic.

4. The mask stowage container of claim 3 , wherein the first first retainer, the first second retainer and the first U shaped bracket comprise an elastically deformable material and wherein the second first retainer, the second second retainer and the second U shaped bracket comprise an elastically deformable material.

5. The mask stowage container of claim 4 , wherein the first first retainer, the first second retainer and the first U shaped bracket comprise a thermoplastic and wherein the second first retainer, the second second retainer and the second U shaped bracket comprise a thermoplastic.

6. The mask stowage container of claim 5 , wherein the first first retainer defines a cylindrical geometry, wherein the first second retainer defines a cylindrical geometry, wherein the second first retainer defines a cylindrical geometry, and wherein second first second retainer defines a cylindrical geometry.

7. The mask stowage container of claim 2 , wherein the first protrusion projects distally away from the first door panel in a first direction and wherein the second protrusion projects distally away from the second door panel in a first direction.

8. The mask stowage container of claim 7 , wherein the first protrusion comprises a lateral width in a second direction, wherein the second protrusion comprises the lateral width in the second direction, the second direction orthogonal to the first direction, wherein the lateral width increases along the first direction to a maximum lateral width.

9. The mask stowage container of claim 8 , wherein the lateral width decreases along the first direction past the maximum lateral width.

10. The mask stowage container of claim 9 , wherein the first neck has a neck lateral width less than the maximum lateral width and wherein the second neck has the neck lateral width less than the maximum lateral width.
