(40 ILCS 5/8-160) (from Ch. 108 1/2, par. 8-160)
    Sec. 8-160. Duty disability benefit - Child's disability benefit. An employee who becomes disabled after the effective date while under age 65 and prior to January 1, 1979 or while under age 70 after January 1, 1979 as the result of an accidental injury incurred - on or after the date he has been included under this Article - in the performance of duty shall receive duty disability benefit, during any period of such disability for which he receives no salary. The benefit shall be 75% of salary at date of injury; provided, that if disability, in any measure, has resulted from any physical defect or disease which existed at the time such injury was sustained the duty disability benefit shall be 50% of salary.
    If the employee's duty disability benefit continues for more than 5 years, on January 1 of the sixth year such benefit shall be increased by 10%.
    The employee shall also have a right to receive child's disability benefit of $10 a month on account of each child less than age 18. Child's disability benefit shall not exceed 15% of the salary as aforesaid; nor shall the total duty disability benefit and child's disability benefit combined exceed 90% of the salary of such employee in his position held at the time of the injury.
    The first payment of duty disability or child's disability benefit shall be made not later than one month after such benefit is granted and each subsequent payment shall be made not later than one month after the last preceding payment.
    Duty disability benefit is payable during disability until the employee attains age 65 if the disability commences prior to January 1, 1979. If the disability commences on or after January 1, 1979 the benefit prescribed herein shall be payable during disability until the employee attains age 65 for disability commencing prior to age 60, or for a period of 5 years or until attainment of age 70, whichever occurs first, for disability commencing at age 60 or older and on or after January 1, 1979, and child's disability benefit shall be paid to the employee parent of any unmarried child less than age 18, during such time until the child marries or attains age 18. The employee shall thereafter upon withdrawal from service receive such annuity as is otherwise provided in this Article.
    Any employee whose duty disability benefit was terminated on or after January 1, 1979 by reason of his attainment of age 65 and who continues to be disabled after age 65 may elect before July 1, 1986 to have such benefits resumed beginning at the time of such termination and continuing until termination is required under this Section as amended by this amendatory Act of 1985. The amount payable to any employee for such resumed benefit for any period shall be reduced by the amount of any retirement annuity paid to such employee under this Article for the same period of time or by any refund paid in lieu of annuity.
