Abstract

A seat belt assembly has an inertia reel belt (10) whose ends are anchored (5) low down to one side of a seat position and which can be pulled out to go over the seat occupant in two strands and be secured by an intermediate fitting (9), to an anchorage (6) at the other side. One strand will go over a shoulder, and to relieve the weight it is supported by a strap (13) which clips to another intermediate fitting (11). The strap may be adjustable in length, it may be formed into a loop for 'strap-hanging' and its anchorage (14) may be adjustable in the fore and aft directions of the seats.

Description

"Improvements relating to Vehicle Seat Belts" This invention relates to vehicle seat belts. It concerns a development of an assembly similar to that described in GB-B-2200529. In that previous assembly, there is a pair of inertia reels with a floor anchorage to one side of a seat position, a belt common to the reels, and means for securing an intermediate point on the belt, when at least partially withdrawn from both reels, to a further floor anchorage on the other side of the seat position. Thus a wheelchair can be moved into position without being obstructed by the belt, which is self-stowing neatly into the reels on the first floor anchorage.
However, in use, the pull of the belt is predominantly downwards, and the portion that goes over the user's shoulder may be heavy and uncomfortable.
It is the aim of this invention to relieve that possible burden, and further to increase the strength and security of the restraint. According to the present invention there is provided a seat belt assembly comprising an inertia reel belt with a main anchorage for both ends to one side of a seat position, first means for securing a first intermediate point on the belt, when at least partially unreeled, to a first, floor anchorage on the other side of the seat position and second means for securing a second intermediate point on the belt co-operable with a second, above shoulder height anchorage laterally of the seat position. Conveniently, the second anchorage wili be on the same side as the main floor anchorage.
By "shoulder height" is meant the level of the shoulders of the occupant of a wheelchair, so that the second anchorage is above the belt as it curves over. Thus the belt is attached in such a manner that it is supported against the downward pull of the reels and its own weight, relieving the pressure on the occupant.
The second anchorage may have an adjustable length strap with means at its free end for releasable attachment to said securing means. These may be a tongue and socket with press-button release as is familiar on seat belts, and the tongue may be freely slidable along the belt, as is also common. Generally, it will be between the first securing means (usually another slidable tongue) and the rearward of the two main belt anchorage points, as that will be the portion of the belt which will go over the user's shoulder.
The second anchorage may have a fitting corresponding to the second securing means (normally another tongue) so that the strap can be formed into a loop with the socket at its free end releasably attached to this fitting. It thus forms a hand hold for "strap-hanging".
The second anchorage will preferably be adjustable in the fore and aft direction of a seat in said seat position, as will the other anchorages. The main one will generally have two inertia reels, as described in GB-B-2200529.
For a better understanding of the invention, one embodiment will now be described, by way of example, with reference to the accompanying drawing, in which:
Figure 1 is a rear perspective view of a seat belt assembly in use, and
Figure 2 is an enlarged exploded detail of that assembly.
In Figure 1, two floor tracks 1 and 2 run in the fore- and-aft direction along the floor of a vehicle and a third track 3 is parallel to them just above the windows 4. The track 1 nearest the side has an adjustable double reel anchorage 5 similar to that described in GB-B-2200529, while the other floor track 2 has an adjustable anchorage 6 with a stalk 7 having a socket 8 at its free end to receive and make captive a sliding tongue 9 on the belt 10. There will be conventional press-button release. A further tongue 11 is slidable on the belt 10 between the tongue 9 and the rearward of the two reels on the anchorage 5. It can clip into a socket 12, similar to the socket 8, at the free end of an adjustable length strap 13. This is bolted at its other end to an anchorage 14 which can be fixed at desired positions along the track 3. Near this other end the strap carries a tongue 15 similar to the tongue 9 and, as shown at the top right of Figure 1, this enables the strap to be formed into a loop by engaging the tongue 15 in the socket 12. It can then serve as a hand hold.
But the main function of the strap 13 is to relieve the weight of the belt 10 over the shoulder of the wheelchair occupant, and this is simply done by engaging the tongue 11 in the socket 12, the strap 13 being adjusted to a suitable length and the anchorage 14 being set at an appropriate position along the track 3.

Claims

1. A seat belt assembly comprising an inertia reel belt (10) , with a main floor anchorage (5) for both ends to one side of a seat position and first means (9) for securing a first intermediate point on the belt, when at least partially unreeled, to a first, floor anchorage (6) on the other side of the seat position, characterised by second means (11) for securing a second intermediate point on the belt co-operable with a second, above shoulder height anchorage (14) laterally of the seat position.
2. An assembly as claimed in Claim 1, characterised in that said second anchorage (14) is on said one side of the seat position.
3. An assembly as claimed in Claim 1 or 2, characterised in that said second anchorage (14) includes a strap (13) with means (12) at its free end for releasable attachment to said second securing means (11) .
4. An assembly as claimed in Claim 3, characterised in that said second securing means (11) is freely slidable along said belt (10) .
5. An assembly as claimed in Claim 3 or 4, characterised in that said strap (13) is adjustable in length.
6. An assembly as claimed in Claim 3, 4 or 5, characterised in that said second anchorage (14) has a fitting (15) corresponding to said second securing means (11) so that the strap (13) can be formed into a loop with its free end releasably attached to this fitting.
7. An assembly as claimed in any preceding claim, characterised in that the second securing means (11) is intermediate the first securing means (9) and the rearward of the two main belt anchorage points.
8. An assembly as claimed in any preceding claim, characterised in that said second anchorage (14) is adjust¬ able in the fore and aft direction of a seat in said seat position.
9. An assembly as claimed in any preceding claim, characterised in that said main and first anchorages (5,6) are adjustable in the fore and aft direction of a seat in said seat position.
10. An assembly as claimed in any preceding claim, characterised in that said main anchorage (5) carries two inertia reels from which respective portions of the belt (10) issue. Reference has been made throughout to seat belts. This may not strictly speaking be the correct nomenclature in some countries in which case the term 'safety belt1 or disabled belt1 may be preferred.
