## Background
FIELD OF THE INVENTION
The present invention relates to a system for securing medical oxygen cylinders, specifically to systems for securing medical oxygen cylinders for aircraft seats.
BACKGROUND
Persons suffering from respiratory dysfunctions require respiratory assistance from auxiliary oxygen cylinders. When providing medical assistance inside means of transport, how the oxygen cylinders are secured is a matter of great importance in order to deliver oxygen to the patients without any risk of the cylinders moving about or falling onto the patient, as well as to ensure that the cylinders are held in vertical position during the entire journey. U.S. Published Patent Application 2012/0139304 discloses a seat for ambulances or the like which is specifically designed to hold oxygen tanks.
In the case of air transport, various systems are currently known for the administration of auxiliary oxygen during decompression events in aircraft, such as those described in U.S. Pat. No. 5,154,374, but in the case of medical care aircrafts, the oxygen cylinders must be capable of being removed from the aircraft along with the patient, which requires the provision of adequate systems for securing the cylinders if need be, especially when the patient is seated, in which the securing system can also be applied or removed as required.
SUMMARY OF THE INVENTION
The present invention relates to a system for securing medical oxygen cylinders for aircraft seats. A novel securing system has been invented and is disclosed herein. The securing system is a collapsible universal securing system which can adapt to the majority of the seats on the market and is quick and easy to install.
The fact that the securing system is collapsible facilitates the storage and transport thereof when not in use, just like an ordinary suitcase, via a series of pivots of the parts strategically arranged on the securing system. Moreover, the securing system enables the attachment of two oxygen cylinders for administration of oxygen to two patients, one on either side of the securing system.
In one embodiment, the novel securing system for securing medical oxygen cylinders comprises three main parts and a fitting system: (i) a base configured such as to be positioned on the passenger seat; (ii) an intermediate structure for securing the oxygen cylinders which is parallel to the base and connected to the base by three legs, each comprising a first end connected to the intermediate structure, and a second end connected to the base, with at least one of the two ends of each leg comprising a pivot in common with the base or the intermediate securing structure; and (iii) a gripping structure which comprises an opening connected to the intermediate securing structure by at least one pivot in common with the intermediate securing structure.
When the securing system is in a deployed position thereof, the intermediate securing structure is arranged at an intermediate height of the oxygen cylinders and the gripping structure is perpendicular to the base thereof. When the securing system is collapsed, the intermediate securing structure and the gripping structure are positioned parallel next to the base.
The securing system being fixed to the seat by a fitting system comprising the seatbelt of the passenger's seat and two straps secured from one end to the gripping structure and from the other end to the fitting of the seatbelt to the actual seat.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 to 4 show a novel securing system for securing medical oxygen cylinders for aircraft passenger seats. The securing system includes a base (1), an intermediate securing structure (2) and a gripping structure (3).
The base (1) is positioned on the base of the passenger seat (23), and comprises two cylindrical recesses (12, 12′) for the bases of each of the oxygen cylinders (11, 11′).
The intermediate securing structure (2) for the oxygen cylinders (11, 11′) is arranged parallel to the base (1) and comprises two U-shaped recesses (13, 13′) and a locking part (14, 14′) for each recess (13, 13′), each U-shaped recess (13, 13′) and the locking part (14, 14′) thereof being configured to encircle each oxygen cylinder (11, 11′). In fact, the locking parts (14, 14′), as shown in FIG. 3, comprise two ends, one of which (16) is stationary with a pivot in common with the U-shaped recess, and the other one of which (17) is extendable, which enables the oxygen cylinder to be placed and, once the cylinder is correctly positioned, the locking part is locked, securing the extendable end thereof, so as to prevent the oxygen cylinder from moving or shifting from the position thereof. The intermediate securing structure also comprises two slots (26, 26′) for holding two straps (27, 27′) secured from one end to the slots (26, 26′) and from the other end thereof to the fitting (28) of the seatbelt (25) to the passenger seat (23).
The intermediate securing structure (2) is connected to the base (1) by three legs, (4, 5 and 6) each of which comprises a first end connected to the intermediate structure (2) and a second end connected to the base (1). The first stationary leg (4) comprises a first end connected to the intermediate securing structure (2) by a common pivot, and a second end connected to the base (1) by a pivot (8) in common with said base (1). This first leg also comprises a notch (22) for holding the seatbelt (25) of the passenger seat, when the securing system is in the deployed position thereof. The second and third legs (5, 6) are extendable and each comprise one end attached to the base (1) by a pivot (8′, 8′′) in common with said base (1) and a second end connected to the intermediate securing structure by a removable pin (9).
The gripping structure (3) comprises (i) a main member connected to the intermediate securing structure (2) by two common pivots (7, 7′); (ii) two latches (10, 10′) for securing the top of the oxygen cylinders (11, 11′); and (iii) an adjustment part (18) which consists of a bolt (19) passing through the gripping structure (3), comprising a first end attached to a cone (21) for resting on the backrest (24) of the seat, configured to rest on the backrest (24) of the seat when the securing system is in the deployed position thereof, and a second end attached to an adjustment wheel (20) provided on the side of the gripping structure that is opposite the backrest (24) of the seat; and (iv) a flexible handle (15) which facilitates the transport of the securing system, in both the collapsed and deployed positioned thereof.
When the securing system is in the deployed position thereof, as shown in FIG. 3, the intermediate securing structure (2) is located at an intermediate height of the oxygen cylinders (11, 11′), and the gripping structure (3) is located perpendicular to the base (1); however, when the securing system is collapsed, as shown in FIG. 4, the intermediate securing structure (2) and the gripping structure (3) are both located parallel next to the base (1).
While at least one exemplary embodiment of the present invention(s) is disclosed herein, it should be understood that modifications, substitutions and alternatives may be apparent to one of ordinary skill in the art and can be made without departing from the scope of this disclosure. This disclosure is intended to cover any adaptations or variations of the exemplary embodiment(s). In addition, in this disclosure, the terms “comprise” or “comprising” do not exclude other elements or steps, the terms “a” or “one” do not exclude a plural number, and the term “or” means either or both. Furthermore, characteristics or steps which have been described may also be used in combination with other characteristics or steps and in any order unless the disclosure or context suggests otherwise.
