Application February 20, 1937, Serial No. 126,860 .In Sweden April 1, 1936 7 Claims.

The present invention relates to a device of support for parachutes, preferably of the harness type and fitted with a central locking device as well as two other locking devices called side locking devices, which latter are controlled by the former.

In the United States patent applications Serial Nos. 96,282 and 99,802, a device of support of this type is disclosed in which the central locking device consists of one main portion, which is indivisible when being releasably actuated. Upon the release of the said locking device, the body encircling strap and/or shoulder straps comprised in the device of support are altogether freed from their engagement in the said locking device. Further the so-called leg straps are permanently connected with the central locking device either directly or through other straps.

The principal object of the present invention is to provide a. device of support for parachutes of the type described, but with a central locking device of novel design reducing or eliminating the risk of the said locking device being damaged by striking against the ground, after it has been released.

Another-object of my invention is to provide a device of support of the type described in which the upper ends of the leg straps, upon the release of the central locking device, are freed from any connection with any other part of the device of support.

Still another object of the invention is to provide a parachute harness equally comfortable as the standard parachute harness adopted by the United States Air Corps in 1924, but with the additional facility of release by a single manoeuvre by the parachutist.

These and other objects will be apparent according as the following description proceeds. reference being had to the accompanying drawings showing by way of example an embodiment of the new device of support.

The function of the new device of support is as follows:

When the harness is to be put on, the wearer first puts his arms through the loops formed by the shoulder straps in about the same manner as a waist coat is put on. The main portions 22 and 23 of. the central locking device are then joined by inserting the protruding member 34 into the middle of the space between the two outer covers of the main portion 23. On account of the tapering shape of the member 34, the claws 48 and 4'! are thereby moved further apart, and after the member 34 has been inserted as far as possible, the claws 46 and-41, through the influence of the spring 86 as well as the spring 94 in the side locking device 24 are brought into engagement with the recesses of the said claws. The handle 13 is then laid down and secured in position by the spring 14 and the peg 19. The two main portions are further secured to each other by the peg .68. The seat portion of the harness is then placed in position, the leg straps l4 and i5 are carried upwards from between the legs of the wearer and connected with the side locking devices 24 and 25. ness may beadjusted through the buckles l8, Ii, 32, 33, 35, 39.

If the wearer wishes to get free from the barness, he first pulls the handle 13 upwards, after it has been released from the engagement of the 92 is a support for the steering If necessary, the harspring 14. The handle '13 is then turned downwards, causing the claws 46 and 41 to be moved further apart through the action of the triangular peg 5|. The members 59 and,85 are then carried upwards through the lever devices described above, the upward movement being transmitted throughthe transmission wires 39 and 40 to the side locking devices 24 and 25. The pawls 4| and 42 in the said devices are carried aside, thereby releasing the snap hooks 38 and 3|, whereby the leg straps l4 and I5 arefreed at their upper ends. Immediately afterwards, the claws 46 and 41 are carried so far apart as to cause the connecting member 34 to be altogether free from its engagement with the main portion 23. The intermediate connection between the shoulder straps l2 and I3 and the straps l8 and I9 via the central locking device then ceases, and the wearer can free himself from the device of support in the usual manner.

As described above, it is necessary that the side locking devices are released shortly before the two main portions are separated, because after 'the said separation has been effected, it is impossible to actuate the side release devices through the central locking device.

A number of variations within the scope of the invention are possible. Thus the device of support, instead of being 01' the harness type comprising shoulder straps connected with suspension straps as well as seat straps, can be of the so called life belt type, which consists of a broad waist strap and generally one strap across the oneshoulder, the suspension strap being fixed atthe back of the waist strap. Furtherihe invention can be applied to such harness, in which the suspension straps extend directly into the central locking device, thus without the branches, [2, l3 shown on Fig. 1.

Further the constructional design of the central locking device may vary. The connection between the two main parts can thus be effected by locking pistons engaging into openings of hollow devices.
