Abstract
Provided in this disclosure is an adaptable vehicle seat belt for wheelchair that can be selectively modified to provide a pin connector mode and alternatively a three-point connector mode that provides safe restraint to non-compliant wheelchairs. The present adaptable wheelchair vehicle seat belt includes a height adjuster belt and a retractor belt that terminates with a female buckle. The height adjuster belt and the retractor belt both slideably engage a dual slot tongue. A pin connector tongue is adapted to freely slide along the retractor belt between the female buckle and the dual slot tongue. The pin connector tongue is adapted to selectively engage an extension belt, used in the three-point connector mode, or a pin connector mounted to the wheelchair in a pin connector mode. In the latter aspect, the dual slot tongue securely connects with the female buckle.

Description
IV. DETAILED DESCRIPTION
[0035] Referring now to the drawings wherein the showings are for purposes of illustrating aspects of the article only and not for purposes of limiting the same, and wherein like reference numerals are understood to refer to like components:
[0036]
[0037] As particularly shown in
[0038] As particularly shown in
[0039] In a pin connector mode of the adaptable wheelchair vehicle seat belt 10, the keyhole 32e is configured for optional secure engagement with a pin connector 62 mounted on the wheelchair 52 when deployed in the pin connector mode (described in detail hereinbelow). The enlarged, triangular portion is sized to easily admit and receive the pin connector 62, and then the pin connector 62 is slid downward for secure engagement with the round end. The clip end 32c also includes an aperture 32f that engages a mating structure inside the second female buckle 44 in order to securely retain the clip end 32c within the second female buckle 44 until selectively released in a three-point connection mode of the adaptable wheelchair vehicle seat belt 10, as will be explained in detail hereinbelow.
[0040] In particular reference now to the partially exploded perspective view of
[0041] The upper wall anchor point 12 supports the height adjuster belt 22. As shown in
[0042] With continued reference to
[0043] With continued reference to
[0044] The length of the first belt 42 is varied by selectively sliding the end 42b of the first belt 42b through the second adjustable buckle 46 until the desired length is obtained for securement of the wheelchair in the three-point connection mode, as will be described in detail hereinbelow. The end 42b can be retained from free movement by a second hook-and-loop fastener section 42c attached thereto which is securely engaged to a second mating hook-and-loop fastener section 48a attached to the second belt 48.
[0045] In particular reference now to the partially exploded perspective view of
[0046] A third female buckle 50 of the belt extension 40 is connected to a first male floor buckle portion 54a secured to the floor of the vehicle behind the wheelchair 52 so that the belt extension 40 is located between the wheelchair 52 and its wheel. The length of the belt extension 40 is adjusted by varying the length of the first belt 42 by sliding through the second adjustable buckle 46, so that the second female buckle 44 is set at the desired location by the hip of the wheelchair occupant. The retractor belt 24 is extended so that the clip end 32c of the pin connector tongue 32 engages with the second female buckle 44.
[0047] The retractor belt 24 is further extended so that the first female buckle 28 engages with a second male floor buckle portion 54b secured to the floor of the vehicle on the opposite side of the wheelchair 52 from the first male buckle portion 54a, alongside and behind the wheelchair 52. In this manner, the portion of the retractor belt 24 between the pin connector tongue 32 and the first female buckle 28 is between the wheelchair 52 and its opposite wheel so that the portion of the retractor belt 24 functions as a lap belt 24c for the wheelchair occupant. Similarly, the portion of the retractor belt 24 between the pin connector tongue 32 and the dual slot connector 30 functions as a shoulder belt 24b for the wheelchair occupant, thereby providing the three-point connection.
[0048] In particular reference now to the partially exploded view of
[0049] The belt extension 40 is removed for this mode. A wheelchair WC/19 lap belt 60 is installed on the wheelchair 52. As shown in
[0050] The retractor belt 24 is extended so that the keyhole 32e of the pin connector tongue 32 engages with the pin connector 62a on the opposite side of the wheelchair 52 from the adaptable wheelchair vehicle seat belt 10. The enlarged head 62ai of the pin connector 62a is received into the enlarged, triangular portion 32ei of the keyhole 32e and the tapered shank 62aii slides into the round end 32eii of the pin connector tongue 32, where the round end 32eii has a diameter that mates with the diameter of the polymer sleeve 62aiii of the tapered shank 62aii. In this manner, the pin connector tongue 32 securely engages the enlarged head 62ai of the pin connector 62a and thereby retains the wheelchair 52. The retractor belt 24 is further extended so that the first female buckle 28 engages with the clip end 30c of the dual slot tongue 30. In this manner, the retractor belt 24 functions as a shoulder belt 24b for the wheelchair occupant. The wheelchair WC/19 lap belt 60 is directly secured to the wheelchair 52 and thereby provides effective restraint.
