ABSTRACT:
A single fasten/release point is provided in a combined shoulder harness/lap belt restraint of the type having a pair of shoulder straps that extend from a behind-the-head anchor point (or points) down over the occupant's shoulders to side anchors located adjacent opposite sides of the seat, and a center-buckled lap belt that passes between the side anchors across the occupant's lap. The ends of the shoulder straps are looped through friction guides provided on corresponding side anchors and joined to an intermediate fastening point on the adjacent portion of the lap belt in a manner that allows for both slackening of the shoulder straps when the lap buckle is released, and adjustability of the lap belt length when the buckle is fastened. Additionally, breast-high shoulder strap adjusters are provided with auxillary connectors to which the separated, complementary parts of the belt buckle can be releasably attached, for stowing such buckle parts and the adjoining portions of the shoulder straps and lap belt in an orderly configuration, ready for quick donning.
