ABSTRACT:
A spring retainer 10 comprises a housing 12, a spring 14 and an actuator 16.
The housing 12 is formed with a bore 20 and an opening 22 which extends transversely of and intersects the bore 20. The actuator 16 is snap engaged with the housing 12 to retain the spring 14 within the opening 22. At least a part of the actuator 16, such as arm 30, is movable inwardly and outwardly of the opening 22 to alter the extent to which the spring 14 obstructs the bore 20.
The spring retainer 10 finds particular application in allowing removal or adjustment of head rests on vehicle seat backs. The arm 30 can be readily squeezed, even when shielded by padded upholstery on the vehicle seat back, to release the spring 14 from a spigot extending downwardly from the head rest.
