Each of the suspension lines may include an elastomeric insert coupled between a first portion of the suspension line and a second portion of the suspension line. At least a portion of the elastomer insert may be located within an internal volume of the suspension line. ## Claims ### Claim 1 A parachute assembly, comprising: a suspension line; a first elastomeric insert coupled between a first portion of the suspension line and a second portion of the suspension line, wherein at least a portion of the first elastomeric insert is located within an internal volume of the suspension line. ### Claim 2 (depends on 1) The parachute assembly of claim 1, further comprising: a first stitching coupling a first segment of the first elastomeric insert to the first portion of the suspension line; and a second stitching coupling a second segment of the first elastomeric insert to the second portion of the suspension line. ### Claim 3 (depends on 2) The parachute assembly of claim 2, wherein a third segment of the first elastomeric insert is located external to the suspension line, the third segment extending between the first segment and the second segment. ### Claim 4 (depends on 3) The parachute assembly of claim 3, wherein a length of the first segment of the first elastomeric insert is at least 6 inches, the length of the first segment being measured between the first stitching and an opening in the suspension line through which the first elastomeric insert is located. ### Claim 5 (depends on 1) The parachute assembly of claim 1, wherein the first elastomeric insert includes: a first segment located within the internal volume of the suspension line; a second segment located within the internal volume of the suspension line, the portion of the first elastomeric insert comprising at least one of the first segment and the second segment; a third segment located external to the suspension line and extending between the first segment and the second segment; a fourth segment located external to the suspension line and extending from the first segment to a first end of the first elastomeric insert; and a fifth segment located external to the suspension line and extending from the second segment to a second end of the first elastomeric insert. ### Claim 6 (depends on 5) The parachute assembly of claim 5, wherein the fourth segment is coupled to the suspension line by at least one of an adhesive or a heat bonding. ### Claim 7 (depends on 5) The parachute assembly claim 5, wherein the fourth segment includes at least one of a crimp or a knot configured to block the fourth segment from translating into the internal volume of the suspension line. ### Claim 8 (depends on 1) The parachute assembly claim 1, further comprising a second elastomeric insert coupled to the suspension line. ### Claim 9 A parachute assembly, comprising: a canopy; and a plurality of suspension lines coupled to the canopy, wherein each suspension line of the plurality of suspension lines includes an elastomeric insert coupled between a first portion of the suspension line and a second portion of the suspension line, and wherein at least a portion of the elastomeric insert is located within an internal volume of the suspension line. ### Claim 10 (depends on 9) The parachute assembly of claim 9, wherein each suspension line of the plurality of suspension lines further includes: a first stitching coupling a first segment of the elastomeric insert to the first portion of the suspension line; and a second stitching coupling a second segment of the elastomeric insert to the second portion of the suspension line. ### Claim 11 (depends on 10) The parachute assembly of claim 10, wherein a third segment of the elastomeric insert is located external to the suspension line, the third segment extending between the first segment and the second segment. ### Claim 12 (depends on 9) The parachute assembly of claim 9, the elastomeric insert includes: a first segment located within the internal volume of the suspension line; a second segment located within the internal volume of the suspension line, the portion of the elastomeric insert comprising at least one of the first segment and the second segment; a third segment located external to the suspension line and extending between the first segment and the second segment; a fourth segment located external to the suspension line and extending from the first segment to a first end of the elastomeric insert; and a fifth segment located external to the suspension line and extending from the second segment to a second end of the elastomeric insert. ### Claim 13 (depends on 12) The parachute assembly of claim 12, wherein the fourth segment is coupled to the suspension line by at least one of an adhesive or a heat bonding. ### Claim 14 (depends on 12) The parachute assembly of claim 12, wherein the fourth segment includes at least one of a crimp or a knot configured to block the fourth segment from translating into the internal volume of the suspension line. ### Claim 15 A method of testing a parachute assembly, comprising: deploying a canopy of the parachute assembly; increasing a tensile load applied to a suspension line coupled to the canopy; and stretching an elastomeric insert coupled between a first portion of the suspension line and a second portion of the suspension line, wherein at least a portion of the elastomeric insert is located within an internal volume of the suspension line. ### Claim 16 (depends on 15) The method of the claim 15, wherein the elastomeric insert is coupled to the suspension line at a first attachment point and at a second attachment point, and wherein a length of the elastomeric insert, as measured between the first attachment point and the second attachment point, is configured to allow the elastomeric insert to stretch to a length of the suspension line, as measured between the first attachment point and the second attachment point, without breaking. ### Claim 17 (depends on 16) The method of claim 16, wherein the elastomeric insert includes: a first segment located within the internal volume of the suspension line; a second segment located within the internal volume of the suspension line, the portion of the elastomeric insert comprising at least one of the first segment and the second segment; and a third segment extending between the first segment and the second segment and located outside to the suspension line. ### Claim 18 (depends on 17) The method of claim 17, wherein the elastomeric insert further includes: a fourth segment located outside the suspension line and extending from the first segment to a first end of the elastomeric insert; and a fifth segment located outside the suspension line and extending from the second segment to a second end of the elastomeric insert.
