James Martin, Higher Denham, near Uxbridge, England Application August 28, 1950, Serial N0..181,7`4l9l In Great Britain May 15, `1950 p The present invention relates to improvements` in/ parachute equipmentfor'use in aircraft.
-An object `of the-present inventionris toV provide an eicient apparatusas hereinafter set forth,V which can -bere'adily' operated by an airman at will and to suit his requirements. I
According to the present invention there is provided `a container mounted on an aircraft seat adapted tocontain and support the airmans parachute pack while the latter is carried behind his back attached to his harness. The container with the parachute pack forms an adjustable `back rest for` the airman allowing him readily to adopt anumber of seating positionswithout readjustment of hisrseat harness While remaining `iirmly held to his scat against-thevmovements of theairc'raft. j
Broadly vthe invention consists of a container for holding a parachute pack carried by the airman attached-to vhis harness, lthe container being so mounted on an aircraft seat structure and combined with a control actuatedV bythe airman that the container and pack form an adjustable back rest for the airman.
Thus a parachute pack container is attached to the seat structure at its lower end by a hinge connection or the like and at its upper end by a pair of adjustable radius arms the setting of which is controlled by the airman by means of ya hand control and control cable run. The airmans shoulder harness straps are attached to shackles or loops mounted on the upper front edge of the container at, or substantially at, thepoint of attachment of the radius arms, so that the loads from the shoulder straps are transmited direct to the radius arms and thence to the seat structure. The upward component of the loads is passed down through the container frame to the lower hinges aforesaid.
The invention will now be described in detail, and by way of example, with reference to the accompanying drawings, in which:
Fig. 1 is a side view of the general arrangement.
Fig. 2 is a part front view. y
Fig. 3 a sectional side view of radius arms and co-operating parts hereinafter referred to.
Fig. 4 is a section on the line A-A of Fig. l.
Fig. 5 is a View showing the parachute pack container in relation to the seat structure.
Referring to the drawings, a parachute pack container I is attached to the seat structure 2 at its lower end by hinges 3. The container I is shaped at its part 4 so as to receive and `hold a parachute pack. This pack with the parachute therein is carried on the back of the air- 5 Claims. (Cl. 244-122) manland is attached `to his' harness. tainer` with' the `pack forms a back rest for the airman.` As the container is hinged at 3 it is possible for this to be adjusted to various positions. The airmans shoulder harness straps are attached to shackles 2|4 mounted on theupper frontedge ofthe container at the point of attachment of-radius arms 5 `referred to later. Such an attachment allows the loads from the shoulder straps to be transmited direct to the radiusarms and thence to the seat structure.
The upward component `of the loads is passed down through the container frame to the lower hinge`s'3. It will be seen from` the drawings that the container I is a rivetedframe-like structure. I
A llever B is mounted on a cross shaft 'I. This latter carries a similar lever at its other end` to operate the oppositeradius arm. The radius arms 5 each comprise a sliding member 8 and a rlxed'member 9. The member 9 is pivotedv to the seat structure1 2 at the radius arm pivot I0; The lever B operates a spring loaded latch II which `engages until withdrawn, in notches I2 and I3 in the sliding member 8. These notches may be of the :fixed type as shown at I2 or of the self-return type as shown at I3, or a suitable combination of both.
The lever 6 is actuated by an airman through `a cable assembly I4 of any suitable construction. At the end of the cable assembly I4 is an actuating device attached to the seat pan and comprising a hand lever I5, a hand knob I6, a spindle spool I'I, an outer spool I8, a coupling I9 and a cover plate 20.
2I is the cable conduit, 22 a stop and 23 clips of the cable assembly.
In the event of an airman desiring a change of seating position, operation of the hand lever I5, through the cable assembly I4 draws down the lever 6 and withdraws the spring loaded latch II from one of the notches I2 in the sliding member 8. It will be understood that there are two radius arms, one at each side of the seat structure. The withdrawal of the latches allows the sliding members 8 of the radius arms 5 to move endways in the xed members 9. As previously mentioned the members 9 are pivoted to to the seat structure at I0 so that the members 9 can accommodate themselves to any change in position of the container due to the sliding movement of the members 8.
A slot 25 in the sliding member and a pin 26 in the fixed member prevent complete separation of the two members even should the spring The con` 3 loaded latch be kept in the disengaged position.
When the spring loaded latch is engaged in a xed type of notch I2, the airman to move .his seating position fore and aft must operate separate container for holding a parachute.l
pack carried by the airman, means for pivoting CII said container to the seat structure, means for Y adjusting the container in relation to the seat back, and a control actuated by the airmarr for operating saidadjusting means,vthe container andA packl forming an adjustable back restfor the airman.
1 2. In, Acombination with an aircraftl seat, a separate container for holding a parachute pack carried by the airman, a hinge connection to the seat structure at the lower end of said container, adjustable radius arms connected to the upper end of said container, and a hand actuated control for adjusting said container through saidY arms in relation to the seat back. d
3. In combination with an aircraft seat, a separate adjustable container for holding a parachute pack carried by the airman, means for pivoting the container at its lower end to the seat structure, radius arms comprising fixed members, and sliding members, a pivotal connection for the xed members to the seat back, a connection for the sliding members to the upper end of said container, a latch-device cooperating With said sliding members, and means for operating said latch device for adjusting said container, through said arms, in relation to the seat back. 1
4. A combined adjustable parachute pack container and back rest for use by an aircraft seat occupant wearing a back parachute pack, means on said container for pivoting this to the seat back, a pair of adjustable radius arms, each of said arms comprising a xed member pivoted to the seat back, and alsliding member connected to said container, and a'control operated by the ocupant for moving the sliding members relatively to the xed members so as to set the container in predetermined positions in. relation to the seat back.
5. A combined adjustable parachute pack container and back rest for use by an aircraft seat occupant wearing a back parachute pack, means on said container for pivoting this to the-seat back, a pair of adjustable radius arms, each of said arms comprising a fixed member pivoted to the seat back and a sliding member connected to said container, a latch device cooperatingwith Asaid sliding members, and a hand` actuated controlvfor said latch ,device` so that the sliding members can be moved relatively `to the xed members. to set the container through said arms at predetermined positions in relation tothe back of the seat.
