Abstract:

A child safety seat is generally formed of one piece molded material having slots through the back wall of the seat. The harness for securing the child in the seat passes through slots in the seat and is anchored to the rear of the seat at selected vertical locations. The harness is connected to a hook plate having a hook thereon and the anchoring means on the rear of the seat includes a plurality of vertically spaced openings for receiving the hook at selected vertical positions. Means are provided in the receiving opening in the rear of the seat to prevent insertion or removal of the hook except when the hook is in a particular orientation with respect to the receiving opening.

Abstract:

A safety belt tensioning and rewinding retractor has a safety belt storage reel rotatably mounted to a retractor frame, emergency locking means for locking the reel against belt protraction, a member rotatably mounted in the retractor frame and means for limiting rotation of such member in a first rotative direction, a first biasing means connected between such member and reel for biasing the member toward the limiting means and the reel in an opposite belt rewinding direction, means for releaseably connecting the member to the reel to block the bias of the first biasing means when the belt is placed in a position of use and second biasing means for biasing the member in a belt rewind direction such that when the bias of the first biasing means is blocked through the connection of the member and reel, a reduced lower tension is applied to the seat belt in use due to the bias of the second biasing means applied to the reel in a rewind direction. The first and second biasing means include coil springs positioned laterally of one another in a narrow housing positioned against one side wall of the retractor frame with means for interconnecting the second laterally disposed coil spring to the aforementioned member through a serpentine spring connection in a preferred embodiment or a gear drive connection in a second embodiment for driving the member and reel when the bias of the main rewind spring is blocked.
