Abstract
A submarine escape suit is made longitudinally adjustable by elastic adjustment members (20a, 20b) that extend along the sides of the suit between the ankle region and the arms of the suit. This provides a long adjustment length which allows a wide range of wearer heights to be accommodated. The members (20a, 20b) are encased in non-snag covers (29). A central adjustment strap (21) is also provided and is also partially encased in a non-snag cover (35).
Claims19
A submarine escape suit made from a flexible material and comprising a body portion, left and right leg portions and left and right arm portions, and an elastic adjustment member extending from a first point on the suit adjacent an ankle of a wearer to a second point on the suit adjacent an arm of a wearer, the adjustment member having a first contracted disposition in which the first and second points are drawn together to provide a shortened length between said first and second points and a shortened length of both the leg portions and the body portion, and the adjustment member having a first extended position in which the distance between said first and second points is increased to provide increased length of the leg portions and the body portion to fit the suit to wearers of differing heights.
A submarine escape suit made from a flexible material and comprising a body portion, left and right leg portions and left and right arm portions, and an elastic adjustment member extending from a first point on the suit adjacent an ankle of a wearer to a second point on the suit adjacent an arm of a wearer to contract the suit between the points to allow the suit to fit wearers of differing heights, wherein the adjustment member is enclosed in a tube extending between the first and second points and fixed relative to the suit to ensure even contraction of the suit by the elastic adjustment member, and wherein the tube is formed by an elongate cover and the material of the suit, the elongate cover extending over the adjustment member and having spaced side edges connected to said material.
A submarine escape suit of flexible material, comprising:
- a body portion;
- a hood attached to the body portion;
- left and right leg portions connected to the body portion;
- left and right arm portions connected to the body portion;
- a first cover attached to the suit and cooperating with the flexible material of the suit to define a first tube;
- a second cover attached to the suit and cooperating with the flexible material of the suit to define a second tube;
- a first elastic adjustment member attached directly to the suit and extending from an end point on the suit adjacent a first ankle of a wearer to an end point on the suit adjacent a first arm of the wearer, the first elastic adjustment member being substantially confined in the first tube;
- and
- a second elastic adjustment member attached directly to the suit and extending from an end point on the suit adjacent a second ankle of the wearer to an end point on the suit adjacent a second arm of the wearer, the second elastic adjustment member being substantially confined in the second tube,
- wherein each of the adjustment members has:
- a contracted disposition in which the respective end points are drawn together to provide a shortened length therebetween and a shortened length of both the leg portions and the body portion;
- and
- an extended disposition in which the distance between the respective end points is increased to provide increased length of the leg portions and the body portion to fit the suit to fit wearers of differing heights.
