A backboard for immobilizing and transporting injured persons and a head restraining device for employment with such a backboard is provided. The backboard includes a rigid support member, two head engaging members which are slidably received in a track attached to the rigid support member and latching assemblies to hold the head support members in a fixed position relative to the rigid support board. The head support members are designed to be positioned adjacent the head of an injured person who has been placed on the backboard, one head support member on each side of the head. The head support members may be completely removed from the track when not in use. The latching assemblies include a spring biased member which engages the track, due to the spring bias, and holds the head engaging member in a fixed position. The backboard may include body strapping members which include a cloth strap, a ring slidably and rotatably retained by one end of the strap and a snap hook swivelly connected to each ring. The snap hooks are connectable to rods embedded in the hand holds of the support board or to the rings of other strapping members. The backboards may include a foot support assembly which includes a foot plate and two extension members. The foot plate is rotatably attached to two extension members which in turn are slidably attached to the support board.
