## Background
SUMMARY OF THE INVENTION
Three-point seat belts may be retrofitted to a seat belt ready seat frame. In the specification that follows the following terminology will be utilized. The term “seat belt ready” means a seat frame, which without any substantial modification is adapted to be used with a seat belt assembly. The term “connector” as referred to at various times is intended to include commonly used connector components such as a tongue, a buckle, a clasp, or a post-type configuration. The term “Y-junction” will refer to the location at which the webbing connects to a junction, which splits off into two separate directions in the approximate direction of a Y. The term “retractor belt” will refer to the webbing and single connector which extends and retracts from a retractor over the shoulder and chest of an occupant. The term “single lap belt” will refer to the webbing and single connector, which extends across from one side of the lap of an occupant. The term “multi-connecting lap and shoulder belt” will refer to the webbing, Y-junction, and two connectors (or the embodiment wherein a tongue with a male post connector is incorporated therein in lieu of the Y-junction and two connectors) is located on an opposite side of the occupant, extending across the lap of the occupant and connected to both the retractor belt and to the single lap belt. The term “lap belt assembly” refers to the webbing and connectors at the junction of the single lap and multi-connecting lap and shoulder belt. One example of these terms is illustrated by the construction shown in FIG. 3.
A first embodiment of the invention permits a school bus seat belt ready seat frame to be retrofitted with a three-point seat belt. A retractor assembly is mounted inside a housing unit, which is then mounted to the underside of the seat frame. Mounting the housing unit to the underside of the seat frame may include the use of bolts, straps, and/or other means including welding the housing unit to the underside of the seat frame. The retractor assembly mounted inside the housing unit contains a retractor mechanism, as well as the retractor belt, which has mounted on its distal end a seat belt connector, which in the first embodiment is a tongue connector. The retractor belt which serves as a shoulder and chest protective belt extends out of the housing unit and is routed up and over the back of the seat frame, over the shoulder of the occupant and at its distal end is connected to a lap belt assembly. The retractor belt with its mounted connector is preferably routed through or over the seat back cushion. Channels (which are not shown) may be created in the seat back cushion to facilitate such routing of the seat belt. A single lap belt attached to the seat frame contains a buckle connector at its end. A multi-connecting lap and shoulder belt configuration is utilized containing what is in effect a Y-junction with two connectors. The first of the two connectors is a buckle, which releasably attaches to the tongue connector on the retractor belt. The second connector is a tongue connector, which connects to the belt connector on the single lap belt. The described first as well as all other embodiments of the invention may readily be adapted for use in other vehicles, including vans, trucks and cars, with both regular and bench-type seating as well as being adaptable for use as original equipment on new school buses. Alternative embodiments also include the use of the lap belt assembly alone without the use of the retractor belt to accommodate infant or child seats. Also included would be variations where the retractor belt connects to child restraint connectors. Also recognized is that the three-way connection used in the first as well as other embodiments of the invention and which serves to join the lap and shoulder belts may also be used separately of the illustrated retrofit housing.
A second embodiment of the invention provides a retrofit design for a school bus seat belt ready seat frame with multiple seat belt assemblies per bench seat. A retractor assembly in this second embodiment is mounted to the underside of the seat frame beneath the seating area for each occupant and the retractor belt for each occupant is routed similar to the routing for the first embodiment. Such embodiment can be employed for school bus bench seats seating multiple occupants including seats of 26 inches, 32 inches, 39 inches, 45 inches, and 90 inches as well as other size bench seats. Different configurations than as illustrated in FIG. 4 may include variations for left and right seating.
A third embodiment of the invention includes a clasp connector on the retractor belt. The two connectors on the multi-connecting lap and shoulder belt in this third embodiment are a tongue connector with a male post connector. The clasp connector on the retractor belt connects to the male post connector of the multi-connecting lap and shoulder belt. The single lap belt contains a buckle, which releasably attaches to the tongue connector of the lap and shoulder belt.
A fourth embodiment of the invention includes a tongue connector on the retractor belt and the multi-connecting lap and shoulder belt contains two buckles. The first buckle releasably attaches to the tongue of the retractor belt. The second buckle releasably attaches to a tongue connector attached to the distal end of the single lap belt.
Many variations are contemplated in addition to those described above. While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
