Abstract: A tongue assembly for use in an occupant restraint system also having a buckle mechanism and a webbing. The tongue assembly includes a tongue member configured to selectively engage the buckle mechanism, a body formed over a portion of the tongue member, a cam, and a biasing member configured to rotationally bias the cam. The body includes a contact surface. The cam includes a cam surface and is configured to rotate about an axis of rotation between a first locking position and a second free position. When the cam is positioned in the second free position the tongue assembly is free to slide along the length of the webbing, and when the cam is positioned in the first locking position a portion of the webbing is clamped between the cam surface and the contact surface thereby preventing the tongue assembly from sliding along the length of the webbing.
