Abstract

A configurable restraint system (10-10^vi) for a vehicle seat (12, 12′) may comprise a first restraint harness (30-30″) coupled to a first engagement member (32), a second restraint harness (34-34″) coupled to a second engagement member (36), and a third engagement member (50-50″″) configured to be movable between first and second positions relative to the vehicle seat. The first position may be located relative to the vehicle seat so that the first engagement member (32) may releasably engage the third engagement member (50-50″″) to restrain a first occupant of the vehicle seat via the first restraint harness (30-30″). The second position may be located relative to the vehicle seat so that the second engagement member (36) may alternatively releasably engage the third engagement member (50-50″″) to alternatively restrain the first occupant of the vehicle seat via the second restraint harness (34-34″).
