Abstract: Parallel restraint rails (20, 22) each include a hinged vertical restraint lip (32) that pivots between a vertically-extending retracted position and a horizontally-extending cargo-restraining position. Each lip (32) is hinged by pins (34) carried by spaced lugs (33) attached in openings (30) in the rail (20, 22). A torsion spring (36) surrounds each pin (34) to urge the lip (32) into the retracted position. Stop blocks (35) on each lip (32) are each free to rotate past a pawl (41) when the pawl (41) is pivoted and held by a foot pedal (44) by the interconnection of a pin (47) extending from the pawl (41) and a cam surface (45) on the pedal (44). The pedal (44) and pawl (41) are carried by pivot pins (38, 37) and biased by springs (40, 39) within a housing (31) positioned in opening (30). The pawl (41) locks the lip (32) into its restraint position and latches the lip (32) into its retracted position.
