FIELD OF THE INVENTIONSThe embodiments described and claimed herein relate generally to wheelchair securement devices for vehicles. More specifically, at least some of the embodiments described herein relate to a “drop-in” wheelchair securement system for a transit vehicle, such as a bus, train, aircraft, boat or the like.
BACKGROUND OF THE INVENTIONSIt is very commonplace for modern transit vehicles to incorporate wheelchair-friendly seating arrangements. For example, most transit vehicles utilize at least some side-facing seating to increase the aisle-width, whereby the side-facing seating is arranged so that the back of the seated passenger is against a side wall. Generally, the side facing seating is located near the front of the bus. In this way, the width of the aisle is much greater near the front (or the entrance) of the bus to allow wheelchair passengers to easily navigate down the aisle. Usually, the side-facing seating areas incorporate fold-up seats so that the side-facing seating area can easily be converted from a seating or standing area to a wheelchair securement area.
Most transit vehicles which have both forward facing and side facing seating usually include barriers or the like to separate the forward facing seating areas from the side facing seating areas. These barriers are generally vertical panels which are secured to either the floor or the sidewall of the bus. Often times, these barriers are “drop-in” systems which are pre-configured to include wheelchair restraints. As such, the drop-in barriers simplify installation of wheelchair restraints for transit vehicle manufacturers. One example of such a barrier is disclosed in U.S. Pat. No. 6,575,677 (“Craft”). Craft discloses a wheelchair restraint system which mainly comprises a barrier. The Craft barrier divides a forward-facing seating area from a side-facing seating area. The Craft restraint system also includes a wheelchair attachment assembly for anchoring the wheelchair and retractable lap belts which mount to the legs of the barrier. The Craft restraint system further comprises a shoulder belt which mounts to a sidewall of the bus. For other examples of prior art wheelchair restraint systems, see U.S. Pat. Nos. 4,103,934; 6,113,325; 6,428,254; 6,524,039; and 6,966,733.
While the prior art systems may be successful in providing a wheelchair restraint solution for transit vehicles, a number of pressing problems remain with the prior art securement technology. For example, while many of the prior art systems include shoulder belts, the shoulder belt assemblies of the prior art are adapted to be mounted to a sidewall of the transit vehicle. This arrangement requires substantial labor to install in a transit vehicle; not only must the transit vehicle manufacturer mount the barrier to the floor, the manufacturer must also mount the shoulder belt to the wall. This two-step installation process can also be complicated by the layout of the transit vehicle. In some cases, wall space may not be available for the shoulder belt assembly in the area selected for the wheelchair securement system. This could happen if the area selected to be the wheelchair restraint area is not aligned with a pillar between windows. As a result, the prior art systems limit the number of possible seating configurations for a bus.
Furthermore, the prior art barriers include belt retractors which are usually attached to the legs of the barrier. The prior art belt retractors stick outwardly from the barrier and, as such, encroach into an area which otherwise could be occupied by seated or standing passengers when not utilized by wheelchair passengers and present a tripping hazard.
SUMMARY OF THE INVENTIONSThe embodiments described and claimed herein solve at least some of the problems of the prior art wheelchair restraint systems. For example, a first embodiment comprises a barrier having an integrated shoulder belt assembly. Rather than being mounted to a sidewall of the transit vehicle, like the prior art, the shoulder belt assembly of the first embodiment is integrated into the barrier whereby the shoulder belt extends from an upper corner of the barrier near a side wall for convenient access by the wheelchair passenger. As a result, the first embodiment provides a “drop-in” wheelchair securement system that includes most of the necessary restraints for wheelchair passenger (usually, additional wheelchair restraints are required which attach to the front side of the wheelchair thereby preventing rearward movement of the wheelchair). For this reason, a vehicle manufacturer can install the first embodiment much more easily and much more quickly as compared to the installation of the prior art systems. Unlike the prior art, the system of the first embodiment requires only one installation step to install the rear wheelchair restraints, the lap belt and the shoulder belt; i.e., the first embodiment of the barrier need only be mounted to the interior of the bus. In addition, the first embodiment provides greater flexibility for the interior designer. Since the first embodiment does not incorporate a sidewall mounted shoulder belt assembly, the first embodiment need not be located near a pillar.
A second embodiment, like the first embodiment, comprises a barrier which includes an integrated shoulder belt assembly. However, the shoulder belt assembly of the second embodiment is adjustable to accommodate wheelchair passengers of varying size.
A third embodiment comprises a barrier which incorporates an integrated telescoping shoulder belt assembly. In this embodiment, the shoulder belt extends from or through a top end of a vertically mounted telescoping member. The telescoping member is movable from a first position, wherein the telescoping member is disposed generally inside of the barrier, to a second position, wherein the telescoping member is in an extended position. In the first position, the telescoping member is in a storage position, wherein the telescoping member does not greatly encroach into space which could otherwise be used by a standing or seated passenger. In the second position, the telescoping member is in an operable position for a wheelchair passenger, whereby a distal end of the shoulder belt (i.e. the pin connector) is disposed approximately above a shoulder of the wheelchair passenger, within easy reach.
A fourth embodiment comprises a barrier having integrated lap belt assemblies which are mounted at least partially inside of the barrier such that the lap belt assemblies do not significantly protrude beyond an outside surface of the barrier. As compared to the prior art lap belt assemblies, which are mounted to an outside surface of the barrier legs, the fourth embodiment is not obtrusive and does not encroach in space that could otherwise be used by standing and seated passengers. Furthermore, the internally-mounted lap belt assemblies do not present a tripping hazard like the prior art systems.
Other embodiments, which include some combination of the features discussed above and below and other features which are known in the art, are contemplated as falling within the claims even if such embodiments are not specifically identified and discussed herein.
These and other features, aspects, objects, and advantages of the embodiments described and claimed herein will become better understood upon consideration of the following detailed description, appended claims, and accompanying drawings where:
It should be understood that the drawings are not necessarily to scale and that the embodiments are sometimes illustrated by graphic symbols, phantom lines, diagrammatic representations and fragmentary views.

The barrier 20 also includes two integral lap belt assemblies 24 and two integral wheelchair restraint assemblies 26, which are mounted internal to the barrier 20 and at least partially within the two legs 22. Although
The barrier 20 also includes an integrated shoulder belt assembly and telescoping member 28. As depicted, the shoulder belt assembly includes a shoulder belt 44 and a connector 58 for connecting to either or both of the male and female connectors 50, 54. Alternatively, the shoulder belt 44 could attach at any point on the lap belt assemblies 24. Although the shoulder belt assembly 28 would be functionally operable if fixed in the lowered position as depicted in
The telescoping member 29 could be manually operable, wherein the user would pull the member 29 upwardly to the extended position. In such a case, locking members could be used to lock the telescoping member in the extended position and/or at the retracted position. In addition, the locking members could be adapted to lock the telescoping member 24 at varying heights to accommodate passengers of varying height.
The barrier could also include mechanical means for extending and/or retracting the telescoping member 24. For example, a gas or coiled spring could be used to bias the telescoping member 24 towards the extended or retracted position. If towards the extended position, a locking member could be used to lock the telescoping member 24 in the retracted position. To extend the telescoping member 29, the user would simply release the locking member through a hand or foot release lever or through electronic means. To retract the telescoping member, the user would simply push the telescoping member 29 to the retracted position and engage the locking member. The opposite would apply if the spring biased the telescoping member towards the retracted position.
Alternatively, a two-way pneumatic cylinder or an electric motor could be used to extend and retract the telescoping member 29. Controls for the member 29 could be provided near the barrier 10, or at a remote location such as the driver's station.

The wheelchair securement system 110 comprises a barrier 120 with two flanges or brackets 122 for engagement with a floor of a vehicle 80. Although shown with two flanges 122, any number of flanges(s) is contemplated including a single flange. Furthermore, although the figures depict the barrier being engaged with a floor of the vehicle 80, it is contemplated that the barrier could include flanges which engage with a sidewall or even a ceiling of the vehicle.
The barrier 120 also includes two integral lap belt assemblies 124, two integral wheelchair restraint assemblies 126, and an integral shoulder belt assembly 128, each of which are disposed generally inside of the barrier. As shown in
Referring again to both
As shown, the only portion of the assemblies 124, 126, 128 that protrude from the barrier 120 are the lap belts 140, 142, the lap belt buckle (or connector) 150, 152, the shoulder belt 144, the shoulder belt connector 158, the restraint belts 130, 132, and the wheelchair fasteners 134, 136. One of the lap belt assemblies 124 includes a male connector 150 and the other lap belt assembly 124 includes a female connector 154. With regards to the restraint assemblies 126, each of the assemblies includes a wheelchair fastener 134, 136, which could be any type of fastener known to a person of ordinary skill in the art. The shown fastener is an anchor 134, 136, which can be easily attached to and easily removed from any portion of wheelchair 70, such as a structural member.
The wheelchair barrier includes retaining members 170, 172, 174, 176, 178 to hold the belts and straps 130, 132, 140, 142, 144 when not in use. The retaining members 170, 172, 174, 176, 178 not only reduce the noise associated with the connectors 150, 154, 158 and fasteners 134, 136 but also reduces potential damage to the barrier. Without the retaining members, the connectors and fasteners would otherwise be free to vibrate and bang up against the barrier as the vehicle was in use. Moreover, the retaining members hold the connectors and fasteners flush up against the barrier, thereby reducing any potential tripping hazard for passengers. As shown in the figures, the retaining members 170, 172 are peg-like structures, while the retaining member 174 is a male connector, the retaining member 176 is a female connector, and the retaining member 178 is a pin connector like structure.
The wheelchair barrier 120 also includes a remote control device with a release latch 190 for releasing one or more of the retractors 180, 182, 184, 186, 188. For example, the embodiments could include the system described in provisional application No. 60/705,452 and PCT application Ser. no. PCT/US06/30085 (which are incorporated herein by reference).
