Each segment is connected to the rail at a joint OR and connected to a host frame at a joint OF. The siderail also includes an inner link longitudinally intermediate the outer link segments and connected to the rail at a joint IR and to the host frame at a joint IF. The head side outer link segment extends longitudinally from approximately the head end of the rail lower edge toward the inner link without longitudinally overlapping the inner link. The foot side outer link segment extends longitudinally from approximately the foot end of the rail lower edge toward the inner link without longitudinally overlapping the inner link. ## Claims ### Claim at position 1 -17. (canceled) ### Claim 18 A siderail for a patient bed, the siderail comprising: a rail main body having a lower edge extending longitudinally from a head end to a foot end, a first outer link segment hinged to the rail main body adjacent the head end, and a second outer link segment hinged to the rail main body adjacent the foot end, wherein the first outer link segment and the second outer link segment have a thickness that is substantially the same as a thickness of the rail main body, the first and second outer links folding in unison relative to the rail main body from a first position situated substantially vertically beneath the rail main body to a second position generally overlapping the rail main body as the rail main body is moved relative to the patient bed from a raised position to a lowered position. ### Claim 19 (depends on 18) The siderail of claim 18, wherein the first outer link segment comprises a generally L-shaped structure including a first portion extending generally parallel with the lower edge of the rail main body and a second portion extending generally perpendicular to the lower edge of the rail main body. ### Claim 20 (depends on 19) The siderail of claim 19, wherein the rail main body has a notch adjacent the head end and an end of the second portion of the first outer link segment is received in the notch. ### Claim 21 (depends on 20) The siderail of claim 20, wherein the end of the second portion of the first outer link segment is hinged to the rail main body within the notch. ### Claim 22 (depends on 19) The siderail of claim 19, wherein the first portion of the first outer link segment is spaced from the lower edge of the rail main body by a sufficient distance to prevent pinching of a user's fingers during raising and lowering of the rail main body. ### Claim 23 (depends on 18) The siderail of claim 18, wherein the second outer link segment comprises a generally L-shaped structure including a first portion extending generally parallel with the lower edge of the rail main body and a second portion extending generally perpendicular to the lower edge of the rail main body. ### Claim 24 (depends on 23) The siderail of claim 23, wherein the rail main body has a notch adjacent the foot end and an end of the second portion of the second outer link segment is received in the notch. ### Claim 25 (depends on 24) The siderail of claim 24, wherein the end of the second portion of the second outer link segment is hinged to the rail main body within the notch. ### Claim 26 (depends on 23) The siderail of claim 23, wherein the first portion of the second outer link segment is spaced from the lower edge of the rail main body by a sufficient distance to prevent pinching of a user's fingers during raising and lowering of the rail main body. ### Claim 27 (depends on 18) The siderail of claim 18, wherein the first outer link segment and the second outer link segment are shaped as mirror images of each other. ### Claim 28 (depends on 18) The siderail of claim 18, wherein the first outer link segment is separated from the second outer link segment to define a gap therebetween. ### Claim 29 (depends on 28) The siderail of claim 28, further comprising an inner link hinged to the rail main body and including a portion situated in the gap. ### Claim 30 (depends on 29) The siderail of claim 29, wherein the first and second outer link segments fold relative to the rail main body about a first axis, the inner link folds relative to the rail main body about a second axis, and the second axis is spaced from and substantially parallel with the first axis. ### Claim 31 (depends on 30) The siderail of claim 30, wherein the second axis is lower in elevation than the first axis. ### Claim 32 (depends on 18) The siderail of claim 18, wherein the first and second outer link segments each comprise an arm and a separately manufactured panel. ### Claim 33 (depends on 18) The siderail of claim 18, wherein the first and second outer link segments are connected to the rail main body near respective longitudinal ends of the rail main body.
