A patient support apparatus comprising: a first frame; a second frame pivotably coupled to the first frame; a drive secured to the first frame and the second frame, the drive operable to move the second frame relative to the first frame, wherein the drive includes a release mechanism which is operable to disengage a portion of the drive to allow the second frame member to move freely relative to the first frame; and an activation assembly for activating the release mechanism of the drive, the activation assembly including: a pivot pin configured to engage with the second frame; a bracket positioned on the pivot pin and pivotable about the pivot pin relative to the second frame, the bracket including a lever arm configured to engage a motion transfer link coupled to the release mechanism such movement of the lever arm is transferred through the transfer link to the release mechanism; a bias member engaged with the bracket to move with the bracket and configured to engage a pair of spaced apart motion limiters (50, 52) secured to the second frame, the bias member including a body and a pair of arms (86, 88) positioned on opposite sides of the body, the arms (86, 88) each configured to engage a respective motion limiter (50, 52) and maintain engagement with both motion limiters (50, 52) when the activation assembly is in a neutral state; and a handle coupled to the bias member, the movement of the handle resisted by the bias member and transferred from the handle to the lever arm. a first frame; a second frame pivotably coupled to the first frame; a drive secured to the first frame and the second frame, the drive operable to move the second frame relative to the first frame, wherein the drive includes a release mechanism which is operable to disengage a portion of the drive to allow the second frame member to move freely relative to the first frame; and an activation assembly for activating the release mechanism of the drive, the activation assembly including: a pivot pin configured to engage with the second frame; a bracket positioned on the pivot pin and pivotable about the pivot pin relative to the second frame, the bracket including a lever arm configured to engage a motion transfer link coupled to the release mechanism such movement of the lever arm is transferred through the transfer link to the release mechanism; a bias member engaged with the bracket to move with the bracket and configured to engage a pair of spaced apart motion limiters (50, 52) secured to the second frame, the bias member including a body and a pair of arms (86, 88) positioned on opposite sides of the body, the arms (86, 88) each configured to engage a respective motion limiter (50, 52) and maintain engagement with both motion limiters (50, 52) when the activation assembly is in a neutral state; and a handle coupled to the bias member, the movement of the handle resisted by the bias member and transferred from the handle to the lever arm. a pivot pin configured to engage with the second frame; a bracket positioned on the pivot pin and pivotable about the pivot pin relative to the second frame, the bracket including a lever arm configured to engage a motion transfer link coupled to the release mechanism such movement of the lever arm is transferred through the transfer link to the release mechanism; a bias member engaged with the bracket to move with the bracket and configured to engage a pair of spaced apart motion limiters (50, 52) secured to the second frame, the bias member including a body and a pair of arms (86, 88) positioned on opposite sides of the body, the arms (86, 88) each configured to engage a respective motion limiter (50, 52) and maintain engagement with both motion limiters (50, 52) when the activation assembly is in a neutral state; and a handle coupled to the bias member, the movement of the handle resisted by the bias member and transferred from the handle to the lever arm.
