A head restraint assembly 10 is disclosed having an adjustable head restraint member 11 which is securable in position between a forward position and a rearward position by a helical coil locking member 14. The locking member 14 is, in a normally relaxed state, of smaller internal diameter than the external diameter of a transverse support rod 24 with which it is engaged. By rotation of one end portion 19 of the locking member 14 with respect to the other end portion 21 the locking member 14 is partially unwound thereby releasing its locking grip on the support rod 24.
