Arm net system for ejection seats

Claim 2

A seat mounted arm restraint net system for restraining an ejection seat occupant's arm during a seat ejection sequence comprising a seat mounted for ejection from a vehicle, said seat having a back portion and a seat pan portion, a net having one side fixedly secured along its length to said seat proximate to each of said back portion and said seat pan portion, said net normally being in a stowed position, a static line attached to a free side of said net and having one end anchored to said seat and its other end capable of being releasably secured to a vehicle from which said seat is to be ejected, and means connected with said static line and net interjacent the ends of said free side of said net and operable to deploy said net to cast said free side of said net laterally outward from said seat and then inwardly toward said seat to encompass a seat occupant's arm.

Claim 3

A seat mounted arm restraint net system as defined in claim 1 including means on said seat for releasably securing said net in its stowed position.

Claim 4

A seat mounted arm restraint system as defined in claim 1 wherein the anchoring of said static line to said seat is releasable to allow for occupant disengagement from said net and egress from said seat.

Claim 5

A seat mounted arm restraint net system as defined in claim 1 including snubber means between said net and said other end of said static line for preventing movement of said line therethrough in one direction toward said seat, and means for releasing the snubbing action of said snubber means.

Claim 6

A seat mounted arm restraint net system as defined in claim 1 wherein the release of the securing of said other end of said static line is operable upon the obtaining of a predetermined force exerted upon said line as said seat is ejected.

Claim 7

A seat mounted arm restraint net system as defined in claim 1 where said last-mentioned means comprises a toggle secured to said static line, and a toggle arm releasably secured to said toggle at one end and inclined and pivotally mounted at its other end to said seat such that motion from a rearwardly directed position with respect to said seat causes an upward, forward, outward and then inward movement of said toggle with respect to said seat to cause the net secured to said static line to follow said movements to encompass a seat occupant's arms, said toggle being arranged to release from said toggle arm at a predetermined position of said toggle arm.

Claim 8

A seat mounted arm restraint net system for restraining an ejection seat occupant's arm during a seat ejection sequence comprising, a seat mounted for ejection from a vehicle, said seat having a back rest position, a head rest portion and seat pan side portions forming arm rests, a net having one side fixedly secured along its length to said seat at one side of said back rest portion and said seat pan side portion, said net normally being in a stowed position, a static line attached to a free side of said net and having one end anchored to said seat at the one side of said head rest portion and its other end capable of being releasably secured to a vehicle from which said seat is to be ejected, and means connected with said static line and net interjacent the ends of said free side of said net and operably by the ejection movement of said seat for deploying said net to cast said free side of said net laterally outward from said seat and then inwardly toward said seat to encompass a seat occupant's arm.

Claim 9

A seat mounted arm restraint net system for restraining an ejection seat occupant's arm during a seat ejection sequence comprising, a seat mounted for ejection from a vehicle, said seat having a back rest position, a head rest portion and seat pan side portions forming arm rests, a net having one side fixedly secured along its length to said seat at one side of said back rest portion and said seat pan side portion, said net normally being in a stowed position, a static line attached to a free side of said net and having one end anchored to said seat at the one side of said head rest portion and its other end capable of being releasably secured to a vehicle from which said seat is to be ejected, and means connected with said static line and net interjacent the ends of said free side of said net and operably by the ejection movement of said seat for deploying said net to cast said free side of said net laterally outward from said seat and then inwardly toward said seat to encompass a seat occupant's arm.

Claim 10

A seat mounted arm restraint net system as defined in claim 7 including means on said seat arm rest for releasably securing said net in its stowed position.

Claim 11

A seat mounted arm restraint system as defined in claim 7 wherein the anchoring of said static line to said seat at the side of said head rest portion is releasable to allow for occupant disengagement from said net and egress from said seat.

Claim 12

A seat mounted arm restraint net system as defined in claim 7 including snubber means between said net and said other end of said static line for preventing movement of said line therethrough in one direction toward said seat, and means for releasing the snubbing action of said snubber means.

Claim 13

A seat mounted arm restraint net system as defined in claim 7 wherein the release of the securing of said other end of said static line is operable upon the obtaining of a predetermined force exerted upon said line as said seat is ejected.

Claim 14

A seat mounted arm restraint net system as defined in claim 7 where said last-mentioned means comprises a toggle secured to said static line, and a toggle arm releasably secured to said toggle at one end and inclined and pivotally mounted at its other end to the said seat side portion such that motion from a rearwardly directed position with respect to said seat causes an upward, forward, outward and then inward movement of said toggle with respect to said seat to cause the net secured to said static line to follow said movements to encompass a seat occupant's arms, said toggle being arranged to release from said toggle arm at a predetermined position of said toggle arm.

Claim 15

A seat mounted arm restraint net system for restraining an ejection seat occupant's arm during a seat ejection sequence comprising, a seat mounted for ejection from a vehicle, said seat having a back portion and a seat pan portion, a net having one side fixedly secured along its length to said back portion and said seat pan portion, said net normally being in a stowed position, a static line attached to a free side of said net and having one end anchored to said seat and its other end secured to a means for exerting a pull on said static line, and means connected with said static line and net interjacent the ends of said free side of said net and operably to deploy said net to cast said free side of said net laterally outward from said seat and then inwardly toward said seat to encompass a seat occupant's arm.

Claim 16

A seat mounted arm restraint net system for restraining an ejection seat occupant's arm during a seat ejection sequence comprising, a seat mounted for ejection from a vehicle, said seat having a back portion and a seat pan portion, a net having one side fixedly secured along its length to said back portion and said seat pan portion, said net normally being in a stowed position, a static line attached to a free side of said net and having one end anchored to said seat and its other end secured to a means for exerting a pull on said static line, and means connected with said static line and net interjacent the ends of said free side of said net and operably to deploy said net to cast said free side of said net laterally outward from said seat and then inwardly toward said seat to encompass a seat occupant's arm.
