초록 ▼

A bushing assembly for use in a hinge for an automotive vehicle seat assembly comprises a pair of identical interlocking sleeves, each having a pair of opposing tangs extending in an axial direction from an annular portion. Each of the tang portions has a shoulder which is radially outwardly directed and is deflectable. The shoulders on the tang portions engage corresponding recessed ledges on the interior wall of the annular portion of the opposite sleeve so as to snap fit together to form an integral bushing assembly through which a hinge pin is passed. The bushing assembly is positioned around the hinge pin and between the hinge pin and the frame members of the vehicle seat assembly to allow rotation of the upright back of the seat. The sleeves may also be stacked together such that each of the tang portions snap into engagement with the annular portions of the adjacent sleeve to form a flexible bushing assembly of variable length.
