• a cam member rotatably coupled to the frame, wherein the cam member extends along a central axis and includes a first engagement feature positioned at a first radial distance from the central axis and a second engagement feature positioned at a second radial distance from the central axis, larger than the first radial distance, wherein the web extends between the cam member and the base portion, and wherein the cam member is rotatable to drive at least one of the first engagement feature and the second engagement feature toward the base portion to engage the web and restrict movement of the web through the opening in at least one direction.

A restraint system comprising:

• a web;
• a frame having a first end portion, a second end portion, and an opening between the first end portion and the second end portion, wherein the first end portion includes an upper surface portion, a curved surface portion forming an edge of the opening, and a lower surface portion, and wherein the web extends along the upper surface portion, through the opening, and along the lower surface portion;
• and
• a cam member rotatably coupled to the frame, wherein the cam member extends along a central axis and includes a cam surface portion having a plurality of protrusions, wherein the cam surface portion is eccentrically oriented relative to the central axis, and wherein the cam member is rotatable to move an individual protrusion toward the horizontal surface portion to engage the web and restrict movement of the web.
