No seat belts. My dads Chevy stationwagon that my dad and mom and there 7 kids and a neighbor kid could all travel in and no one had a seat belt. Mon held the youngest baby, and the second youngest sat between them, 4 kids in the back seat, no third row seat, any kids without a seat sat in the back of the station wagon on the flat surface with the camping gear. 5.5 HP outboard in the trunk, And we had a row boat on the roof, a canoe and a small sail boat on top of the boxed in utility U-Haul trailer that my dad bought and boxed in, and all the kids bikes roped beside the canoe and small sail boat, tents and kitchen tent, and fishing gear and all camping gear and clothes and some food in the trailer, and we all went camping with only one vehicle for 2 weeks. No child seats, no seat belts. And the car had no air-conditioning, and my mother would bring a bag with ice and cold water in a baby bottle, and cold wash-cloths for the youngest if it got too hot. We would lower the back window and open windows to get air to flow through the car to cool off. And we did that many years, always in late August when the lake water had had time to warm up to a temperature that was safe if anyone flipped any of the boats.
