ABSTRACT:
A spring assembly of the kind having a coiled strip spring member (34) supported at one end on an arcuate drum portion (16) about which it is reverse wound and coiled at its other end about an abutment (20) further includes a base plate (10) mounting the drum portion (16) and a second base plate (18) mounting the abutment (20), the base plates (10) and (18) being interconnected by pins (32) attached to base plate (18) running in slots (26, 28) provided on base plate (10) so as to prevent relative movement of the base plates which would allow the spring to coil further about the abutment (20). The base plate (10) is provided with a cover (40) with which it forms a housing portion and the base plate (18) is provided with a cover (38) with which it forms a second housing portion. The assembly can be dropped on to support pins (14, 22) attached to respective halves (42, 44) of a hinge, e.g. of an automobile trunk or lid.
