(1) Except as provided in subsection (2), personal protection insurance benefits are payable for a survivor's loss which consists of a loss, after the date on which the deceased died, of contributions of tangible things of economic value, not including services, that dependents of the deceased at the time of the deceased's death would have received for support during their dependency from the deceased if the deceased had not suffered the accidental bodily injury causing death and expenses, not exceeding $20.00 per day, reasonably incurred by these dependents during their dependency and after the date on which the deceased died in obtaining ordinary and necessary services in lieu of those that the deceased would have performed for their benefit if the deceased had not suffered the injury causing death. Except as provided in section (2) the benefits payable for a survivors' loss in connection with the death of a person in a single 30-day period shall not exceed $1,000.00 for accidents occurring before October 1, 1978, and shall not exceed $1,475.00 for accidents occurring on or after October 1, 1978, and is not payable beyond the first three years after the date of the accident.

The maximum shall apply to the aggregate benefits for all survivors payable under this section on account of the death of any one person.
